Analysis of Earthmoving Equipment

Analysis of Earthmoving Equipment Earthmoving equipment is typically used due to the high efficiency of the construction work. In early era human power has been used to move earth requiring plenty of time and manpower. But with the development of technology earthmoving equipment has been introduced to the construction field and nowadays more advanced and easily maneuverable earthmoving equipment are available. Thus the time consumption and manpower is greatly reduced resulting a more efficient and time saving construction methods. There are number of earthmoving equipment that can be used for the construction and each equipment provides a different purpose. (equipment, 2014) Excavators Figure 1: Excavator Excavators are mainly se to excavate soil. Excavators are very useful in deep excavations as well as it can be used for different applications by changing the bucket to different gadgets. Typically excavators are used in cutting trenches, digging holes and foundation pits, Handling of Material , Construction, General grading or landscaping work, Mining of minerals and gems, River dredging, pile driving, , shafts drilling for footings and blasting of rocks etc.(equipment, 2014) Backhoe Figure 2: Backhoe Backhoe is a versatile equipment which widely used in construction industry. It is a combination of an excavator and bulldozer. It can be used for quick earthmoving work and it can replace both excavator and bulldozer if the scale of the work is low. Also due to its 4 wheel system it can easily move through any rough terrain. Hence backhoe is typically seen on any construction field. The levers are operated by hydraulic pistons and the bucket can be replaced with other useful add-ons accordance to the requirement. (equipment, 2014) Bulldozer Figure 3: Bulldozer Bulldozer is a very powerful equipment which can be used to move earth and prepare surfaces. Due to its high power and belt wheel system it is used to move heavy soil lumps in one go. It has a large plate or blade attached to its front which facilitates pushing mechanism of large soil, rubble, gravel or other materials. By changing the blade to a ripper it can be used for farming or ground loosening work. Skid steer loader Figure 4: Skid Steer Loader Skid steer loader is a small scale equipment which can be used for quick work and for the places where large equipment cannot be accessible. Easily maneuverability is one of the main advantage of the equipment. Also it can be used to load soil into dump trucks. The main characteristic of this equipment is its wheel can be rotated independently allowing it to turn in limited spaces. (equipment, 2014) Trencher Figure 5: Trencher Trencher is another useful equipment that can be used to dig trenches in construction work.trencher has a long arm equipped with rotating belt of blades. The blades dig trenches while the equipment is moving along the required line. This can also be used for digging of irrigation channels, foundation trenches, road drainages etc. trenchers are also used in farming industry as well. (equipment, 2014) Motor Grader Figure 6: Motor Grader Motor grader is another useful earthmoving equipment. This equipment is heavily used in road construction. The main purpose of a motor grader is to prepare surfaces according to required slopes and angles. With the long blade attached to front arm of the equipment it can prepare flat surfaces. The motor grader is also referred to as road grader due to its heavy usage in road construction. This equipment is also used in irrigation construction as well. (History of the Bulldozer. Retrieved 2008-12-17.) For the given project I would use excavators, backhoes and Skid steer loader. The main reason for the excavator the amount of soil needs to be excavated to prepare the basement. Backhoes will be used to small scale work and slope preparation work. Skid steer loaders will be used for the small work where space is limited for big equipment. To ensure the equipment is used efficiently, effectively and economically I will preplan the earth moving process and schedule the work plan with allocating time for each equipment so that every equipment is not used at once wasting time. Also I will allocate specific tie limit for each equipment and the operator should be able to finish the allocated work within the given period of time. With such management mechanisms I can use the provided equipment effectively, efficiently and economically. What methods and resources will you employ to ensure safe and productive operations in deep excavations and trenching for your project? Justify your choice. Support your answer with examples. I will use shoring method to ensure the stability of soil while deep excavating and also a safety officer should be allocated for supervision of excavation work. Excavations will not be done on rainy days. Also the excavations will be done maintaining minimum slope angles for stability. There are several steps that need to be taken in order to assure safe and productive opertaions in deep excavations Preplanning of the work to be done taking following factors into account Traffic Proximity and physical condition of nearby structures Soil classification Surface and ground water Location of the water table Overhead and underground utilities Weather Quantity of shoring or protective systems that may be required Fall protection needs Number of ladders that may be needed Other equipment needs Protective Systems OSHA generally requires that employers protect workers from cave-ins by:   Sloping and benching the sides of the excavation; supporting the sides of the excavation; or Placing a shield between the side of the excavation and the work area. Define types of temporary works required to deal with stability and groundwater problems in the project. Typically during excavation process dewatering has to be done while maintaining stability of slopes. There are several practices used in industry maintain stability. Caissons Caisson is a structure that is developed at area if the   site is ashore, yet in the event that the venture site is seaward, it is built ashore and afterward skimmed to the site seaward. In the caisson technique for development, the unearthing is performed from inside the permanent structure. After the caisson is in position, uncovering from inside the caisson structure starts. As the unearthing is done, the caisson structure begins to sink by its own weight, or if fundamental, by forced burdens. This strategy proceeds until the coveted foundation level is accomplished. Figure demonstrates this procedure schematically. ( Wilson,1873) Figure 7: Caissons Installing Ground Freezing The theory of ground solidifying is to change the water in the soil into a strong mass of ice. This mass of ice is totally impermeable. Ground solidifying is utilized for groundwater cutoff, for earth bolster, for brief supporting, for adjustment of earth for passage removal, to capture landslides and to balance out deserted mineshafts. The principals of ground solidifying are undifferentiated from pumping groundwater from wells. To solidify the ground, a column of stop channels are set vertically in the soil and warmth vitality is expelled through these funnels. Isotherms (an isotherm is a line interfacing areas with equivalent temperature) move out from the stop channels with time like groundwater forms around a well. Once the earth temperature comes to 32  °F (0  °C), water in the soil pores swings to ice. At that point additionally cooling continues. The groundwater in the pores promptly solidifies in granular soils, for example, sands. For example, soaked sand accomplishes magnificent quality at just a couple of degrees underneath the point of solidification. On the off chance that the temperature is brought down further, the quality increments hardly. In strong soils, for example, muds, the ground water is molecularly fortified at any rate to some degree to the soil particles. On the off chance that delicate mud is chilled off to solidifying temperature, a few segments of its pore water to start to stop and it causes the earth to harden. With further decrease in temperature, more pore water solidifies and subsequently more quality pick up is accomplished. When planning for solidified earth structures in firm soils, it might be important to determine generously bring down temperat ures to accomplish the required quality, than in attachment less soils. A temperature of +20  °F might be adequate in sands, though temperatures as low as -20  °F might be required in delicate soils. The outline of a solidified earth obstruction is represented by the warm properties of the fundamental oils and related reaction to the solidifying framework. Arrangement of solidified earth boundary creates at various rates relying upon the warm and water powered properties of every stratum. Ordinarily, shake and coarse-grained soils solidify quicker than muds and sediments. (Jessica Morrison ,2013) Figure 8: Ground freezing method Dewatering Methods Wellpoints The wellpoint comprises of an opened or punctured pipe which is secured with a screen work. At the foot of this pipe is a hole which licenses flying of the pipe into the ground amid foundation. A well-point dewatering framework comprises of a progression of firmly set little distance across wells introduced to shallow profundities. These wells are associated with a pipe or header that encompasses the removal and is joined to a vacuum pump. The development ventures in the well point framework are: 1. The wellpoints are jetted into the ground; 2. The annulars void is filled with filter media; 3. The wellpoints are connected to a header pipe by means of a riser; 4. The header pipe is connected to suction pumps for pumping. Powers, J. Patrick (1992). Figure 9: Well points What types of plant and equipment will you use in substructure and drainage activities in your project? Justify your choice. Support your answer with examples. For the given project first thing that needs to do is providing drainage. While providing proper drainage by means of dewatering pumps and wells. Then to stabilize the earth proper shoring should be needed. Once the shoring is properly established further excavation and substructure work can be commenced. Drainage and dewatering Backhoes Dewatering pumps Drilling machines Hoses Generators etc. Earth stabilizing Shoring machines Cranes Welding plants Backhoes and excavators Substructure work Skid Steer loader Backhoe Excavator Piling machine What techniques of installing piling systems and ground stabilization activities will you use in your project? Justify your choice. Support your answer with examples. The foundation procedure and technique for foundations are similarly critical components as of the outline procedure of heap foundations. Pilefoundation techniques are foundation by heap mallet and exhausting by mechanical auger.In request to evade harms to the piles, amid plan, foundation Methods and foundation hardware ought to be precisely selected.If foundation is to be done utilizing pile pound, then the accompanying components ought to be taken into thought: Size of the pile and the weight of the pile The available head room and space The availability of supporting equipment and machinery The noise pollution and regulations. The driving resistance for the designed drilling Pile driving methods (displacement piles) Methods of pile driving can be categorised as follows: Dropping weight Explosion Vibration Jacking (restricted to micro-pilling) Jetting Drop hammers   Ã‚   A hammer with around the heaviness of the pile is brought a reasonable stature up in a guide and discharged to strike the pile head. This is a straightforward type of mallet utilized as a part of conjunction with light casings and test piling, where it might be uneconomical to bring a steam heater or compressor on to a site to drive extremely set number of piles. There are two main types of drop hammers 1. Single-acting pile hammers which operates using steam or compressed-air comprise a large weight in a cylindrical container. Steam or compressed air rises it up the fixed piston rod. At the top of the blow, or at a reduced height which can be operated by the operator, the steam is cut off and the cylinder falls freely on the pile helmet. 2. Double-acting pile hammers can be run by steam or compressed air. A pilling mount is not mandatory with this mode of hammer which can be fixed to the upperpart of the pile by leg-guides, the pile being directed by a timber structure. When used with a pile mount, back directs are fastened to the hammer to engage with leaders, and only short leg-guides are used to stop the hammer from moving relatively to the top of the pile. These type of hammers are used mainly for sheet pile driving. Pile driving by vibrating Vibratory sledges are normally electrically fueled or using pressurized water controlled and comprises of contra-pivoting unconventional masses inside a lodging connecting to the heap head. The abundancy of the vibration is adequate to separate the skin erosion on the sides of the heap. Vibratory strategies are most appropriate to sandy or gravelly soil. Jetting:to help the entrance of piles into sand or sandy rock, water streaming might be utilized. In any case, the strategy has exceptionally restricted impact in firm to solid muds or any dirt containing much coarse rock, cobbles, or stones. Boring methods (non-displacement piles) Continuous Flight Auger (CFA) Hardware contains a portable base transporter fitted with an empty stemmed flight wood screw which is pivoted into the ground to required profundity of pilling. To shape the heap, cement is put through the flight twist drill as it is pulled back from the beginning. The twist drill is fitted with defensive top on the outlet at the base of the focal tube and is pivoted into the ground by the top mounted turning pressure driven engine which keeps running on a transporter joined to the pole. On achieving the required profundity, profoundly workable cement is pumped through the empty stem of the wood screw, and under the weight of the solid the defensive top is disconnected. While pivoting the wood screw in an indistinguishable bearing from amid the exhausting stage, the ruin is removed vertically as the twist drill is pulled back and the heap is shaped by loading with cement. In this procedure, it is essential that pivot of the wood screw and stream of cement is coordinated that fall of sides of the opening above cement on lower flight of twist drill is evaded. This may prompt to voids in loaded with soil in cement. The strategy is particularly viable on delicate ground and empowers to introduce an assortment of exhausted heaps of different widths that can infiltrate a large number of soil conditions. Still, for fruitful operation of revolving twist drill the dirt must be sensibly free of tree roots, cobbles, and stones, and it must act naturally supporting. Amid operation little soil is brought upwards by the twist drill that horizontal burdens are kept up in the dirt and voiding or extreme slackening of the dirt limit. Be that as it may, if the pivot of the wood screw and the progress of the twist drill are not coordinated, bringing about evacuation of soil amid penetrating perhaps prompting to fall of the side of the gap. Figure 10: Piling and Auguring Underreaming An extraordinary component of wood screw exhausted heaps which is here and there used to empower to misuse the bearing limit of appropriate strata by giving a developed base. The dirt must be fit for standing open unsupported to utilize this method. Firm and to hard muds, for example, the London dirt, are perfect. In its shut position, the underreaming instrument is fitted inside the straight area of a heap shaft, and after that extended at the base of the heap to create the underream appeared in fig. 3.Normally, after establishment and before cement is threw, a man conveying enclosure is brought down and the pole and the underream of the heap is reviewed. (Fleming et al, 1985,) What methods and processes of constructing foundations including will you use in your project? Justify your choice. Describe the resources that you will use for the construction of foundations. Justify your choice. In the event of soils having low bearing limit, overwhelming auxiliary burdens are generally bolstered by giving Raft or tangle establishments. Likewise if the structure is defenseless against subsidence on being situated in mining range or because of questionable conduct of its sub-soil water condition, flatboat or tangle establishments ought to be favored. Raft or Mat Foundations gives an efficient answer for troublesome site conditions, where heap establishment cant be utilized profitably and free section balance gets to be distinctly impracticable. Raft or tangle establishments comprises of thick fortified solid slab covering the whole range of the base of the structure like a story. The piece is strengthened with bars running at right points to each other both close base and top face of the section. Now and again it is important to convey the over the top section stack by a course of action of reversed principle shafts and auxiliary bars, cast solidly with the flatboat piece. The Raftslab for the most part ventures for a separation of 30 cm. to 45cm. on every one of the sides of the external dividers of the structure in that capacity the region of exhuming is marginally more than the range of the structure itself. The unearthing is made to the required profundity and the whole uncovered territory is very much united. This surface, when dry, gives the base whereupon the flatboat or tangle section is laid. Every one of the precautionary measures that are important to be seen amid the strengthened solid development are entirely clung to and promote development is begun simply after the curing of the Raft has been completely done.Halpin, Daniel W.; Senior, Bolivar A. (2010). Describe methods and resources that you will use in processes, undertaking drainage works including culverts and installing services in your project. Culverts and drainage works Excavation The area of the proposed drainage will be set out on the ground by checking with paint and pegs at pit areas. Where works are along edge of existing roadway movement light or stop/go framework might be set up to do works. A trench will then be unearthed between pits utilizing an excavator with material stacked to dump truck. The trench width will differ contingent upon the measure of the pipe. Installation Where drains are being introduced a layer of geotextile material should be put along the framework of the trench and a layer of channel stone might then be put in base of trench to get pipe work. The pipe work should then be laid to the right line and level by utilizing a review laser Backfilling of Ducting The remaining stone might then be put by six ton dumper up to underside of topping where geotextile should be turned out under topping layer. The rest of the depleted might be bested up once surfacing works are done up to wearing course level. Establishment of layer of Geogrid should likewise be done at this stage. All chambers on the deplete lines might be built with pre-thrown solid catch pits and should be put as pipeline continues. (Turner-Fairbank Highway research Center ,1998) Figure 12: Culverts What types of plant and equipment will you use in the construction of superstructure your project? Justify your choice. Support your answer with examples. Construction of superstructure requires lot of machinery and equipment and the uses may vary throughout the different stages of the project. Following are a list of equipment and the uses of each equipment. Equipment Uses Batching plant Concrete Production Concrete pump Concrete pouring to higher levels Tower crane Shifting materials Elevator Shifting materials and laborers Formwork systems Form the structure Scaffolding For higher level work Poker vibrator For compaction of concrete The batching plant will produce concrete required to construction and concrete mixture truck and pump will support to pour concrete to slabs, columns and beams. Tower crane and elevator will help to move goods and laborers respectively. Scaffoldings, formwork systems and poker vibrator will be used for concrete pouring and form the columns, slabs and beams of the building. What methods and resources will you use in undertaking the main forms of structural activities in you project? Include the use of concrete in its various forms as well as the use of structural steelwork. Provide relevant examples. Justify your choices. Mainly concrete will be used together with steel to form the superstructure. Typically formwork will be established first and then concrete together with steel will be used to cast columns, beams and slabs of the building. For the aforementioned task concrete pumps, poker vibrators, laborers and skilled supervisors will be needed. Concrete is typically used for this type of construction work due to its workability. Liquid state of concrete allows us to cast different required shapes and forms of structures with ease. Whereas steel is a pre-fabricated material hence steel does not provide the freedom to use for different shapes. But steel is also a very good construction material which facilitates fast construction. Structural steelwork can be used together with concrete to produce composite structures. Also steel can be used alone for buildings as well. (Concrete Association, 2013) What methods of false work and formwork will you use in the superstructure activities in your project? Provide examples. Justify your choice. What processes of concrete production, delivery and placement will you use in your project? Justify your choice. Formwork implies the surface of the frame and surrounding used to contain and shape wet cement until it is self-supporting. Formwork incorporates the structures on or inside which the solid is poured and the casings and propping which give soundness. Albeit ordinarily alluded to as a component of the formwork get together, the joists, bearers, propping, establishments and footings are actually alluded to as false work. Formwork development may include high hazard exercises like working fueled portable plant like cranes, working at stature and unearthing establishments. The outline of the last solid structure can majorly affect the simplicity of formwork development and the wellbeing and security of individuals amid development. For the most part the more essential and basic the last solid structure, the more secure it is to develop, erect and destroy the formwork. An accomplished formwork creator ought to be counseled amid the plan of in-situ solid structures to empower the wellbeing and dangers amid formwork development and destroying to be considered in the outline. The formwork originator must be equipped in formwork configuration including reporting brief work stages and exceptional gear required for safe formwork development on location. A creator may utilize a specialized standard or a blend of gauges and building standards significant to the plan prerequisites the length of the result is an outline that meets administrative necessities. Concrete production Concrete Batching plant Concrete will be produced in a batching plant to ensure the quality and strength of the concrete. Concrete Delivery Mixture truck Mixture trucks will be used to deliver concrete to the site from the batching plant to prevent loss of workability and quality of concrete Concrete Placement- Concrete pump truck Concrete will be placed to higher levels using a concrete pumping truck. This way we can efficiently pour concrete.   (Concrete Association, 2013) Identify and assess the hazards arising from the substructure activities. Falling of unstabilized soil Falling to deep excavated trenches and pits Hazards associated with excavators Shorings can be weak Damages to underground electrical wires Explain the legal framework of health, safety and welfare and the requirements of the current CDM Regulations. The Construction (Design and Management) Regulations 2015 (CDM 2015) addresses the management of health, safety and welfare of workers in construction projects. CDM 2015 substituted the Construction (Design and Management) Regulations 2007 (CDM 2007) and the Accepted Code of Practice which is providing supporting direction on CDM 2007 was inhibited. CDM 2015 aims to uplift health and safety in the industry by providing guidance to: Rationally plan the work so the risks tangled are succeededthroughout. Have the correct people for the correct job at the correct time collaborate and organize your work have the properinfo about the risks and how they are managed convey information efficiently to those who need to know consult and occupy workers for the risks management activities and educate them how they are being managed The CDM2007 Regulations expect to lessen development mischances and sick wellbeing in Great Britain by empowering the different partners of the development business to enhance in arranging and dealing with their activities contemplating matters of security and wellbeing at an early stage in the venture definition. By beginning concentrating on these basic focuses toward the start of a venture, dangers can be recognized and supervisors can use sound judgment in front of challenges. In this new form of the directions, the HSC concentrates on correspondence and co-appointment between every one of the gatherings required in the development venture and set up a few obligations for each of the distinctive partners. It likewise highlights that the measure of printed material and all the administration brought on by the past rendition of the controls ought to be diminished and the attention put on the arranging and administration. The CDM set up commitments for customers and fashioners. The fundamental commitment forced to the customer is to delegate the primary partners for the arranging and the acknowledgment of development work. By development work, the CDM extensively alludes to the doing of building, structural designing or building development word .Among the dutyholders which take an interest to the doing of the venture are the Client, the Designer, the CDM-Coordinator, the Principal Contractor and the Contractors. (The Construction (Design and Management) Regulations ,2007) Evaluate and justify the role of the planning coordinator who has been appointed to the project. Construction project coordinators plan, organize, and guide the actions of a construction project, under the guidance of a manager. He works on-site most of the time, over looking the day-to-day tasks of the project. He works for residential, commercial and industrial construction companies or for construction departments of companies outside the construction industry. Generally, construction project coordinators: Make contracts and negotiate alterations to contracts with architects, consultants, clients, suppliers, and subcontractors. Suggest and implement QC programs. Make progress reports for clients. Control the acquisition of building materials and land. Hire and supervise subcontractors and staff. During the excavation works the contractor found that the sub-soil in a section of the site to be contaminated. All site activities were halted pending further investigations. Following the investigations it was found that the site was contaminated with caustic soda and from material linked to buried heavy fuel tanks. The client has asked for a design solution to the problem. The contaminated ground can be treated with 5% ferric chloride treat the caustic soda contamination. Proper waterproofing of basement can further ensure that the caustic soda intrusion is completely blocked. Burried heavy fuel tanks should be properly sealed to prevent further leakages. If the contaminated section can be completely removed it should be removed and disposed safely to continue construction work.

Laborers and stakeholders can be affected Sub soil needs to be treated or removed

Overview of The Cold War :: essays research papers

The Soviet Union and the United States served as Allies during World War II. At the end of the war however each side wanted to deal with the aftermath differently. The United States was in favor of a peaceful and cooperative relationship with Germany and their Allies. The Soviet Union wanted revenge on the crimes and atrocities that were committed against them. The United States wanted to push democracy in Eastern Europe yet the Soviets countered this by saying the United States was hypocritical, since at that time the United States supported the Latin countries that were governed by dictatorships. The Soviets were under the impression that this was an effort to boost the UNITED STATES economy. One of the main reasons the Soviets wanted their revenge is because they lost over twenty million citizens in the war. Even though the United States lost 405, 000, this was not as great as the loss suffered by the Soviet Union. Just like when one person gets mad they have to have it their way or no way at all and the Soviets felt this way. They wanted revenge on Germany and did not want to take no for an answer. As a result of World War II the United States came out the most powerful nation in the world, they had learned from their mistakes, as well as the knowledge of how the war could have been prevented. Therefore the United States believed they knew best and ignored the previous isolation policy. Their attitude toward the Soviets was very cocky because they believed they knew what was best. The United States needed to access raw materials, markets for their goods, and security for investments overseas that could only be met in countries with governments like their own. Th is is another reason the United States wanted to push for democracies overseas. President Truman wanted to have a cooperative relationship with the Soviet Union as long as they did what the United States wanted them to do. He wanted to restrain their expansionist impulses and allow the United States to rebuild Germany and their Allies. Truman knew that he could get away with this because American had a nuclear monopoly which attributed to the United State’s power. Josef Stalin the leader of the Soviet Union wanted to force communism on surrounding nations.

Cloud Operating System Architecture

Cloud Computing Architecture Tall Tanager developer. [email  protected] Com Abstract? A bright vision of the future sparks up with the new technologies of cloud computing. A new perspective towards how files, pictures, documents are shared, accessed and modified over the World Wide Web. In this we take a look at the architecture of cloud computers, identify and explain the different layers from client to host. It also discusses how we will be able to design, implement, develop and innovate in the future with cheaper costs, better efficiency by the use of powerful systems on the cloud almost anytime and anywhere around the globe.A world with incredible virtual systems being made affordable for everyone. Looking ahead the next decade, cloud computing promises to collaborate everywhere through mobile devices. Introduction Cloud computing can be seen as a very promising future of computing with cheaper costs, application efficiency and a door opening for millions of people around the g lobe not being able to afford powerful systems for education, work and development.Given the ability that it will allow people to conduct geophysical modeling experiments, render high-end graphics almost anywhere and anytime in he world will lead to innovation by many with ideas being capable of implementing them for an affordable cost. It can store immense amount of data, improve accessibility, secure data by making it available to authorized users only and deploy web scripts for PH, Perl, ASP. NET and several others on the go as it includes a platform for an Apache and MYSELF TM Database Server.Most importantly sharing videos, music and documents across the internet would be far more efficient as files would no longer be required to uploaded instead would require access-permission. From modeling AD graphs to integrate photos, maps with a handful of web services, loud computing would highly benefit large business corporations. Keywords? collaborate, affordable costs, efficiency, in tegrate The Layers – An Outer Look Here is a representation of architecture of a common cloud computer.The first layer being the client layer is a web browser on a mobile or tablet device. An application has three layers, graphical interface layer (user interaction), application layer (the coding-level) and the database layer (for storing data). Figure 1-1 (Graphical Representation of the different layers) Next we have cloud services, the service required for applications to run I. Apache services, database servers etc. This layer cannot be directly modified by the client. Alongside these is the cloud runtime for storage and table services.These could be various applications such as an anti-virus tool, a service for file transfer, POP connection services. Lastly we have the Infrastructure and storage. This has to do with the hardware, the physical design of the system to ensure maximum durability, prevent incidents such as short circuits, ensure cooling etc. Deployment and Us er Experience User Intent & Interface To be able to customize your computer and have a flexible environment to work in sakes an important factor in the overall architectural design of the system.End-users look out more for the design; the speed and accessing their programs with ease rather than worry about the infrastructure or web services. Over here the target needs to be aiming for fast application deployment, services should be updated automatically, and responsiveness should be fast. Designing On Established Trends Cloud computers are deployed on established trends to reduce cost out of the delivery of services as it increases the speed and power at which services are deployed. Cloud computing offers on-demand deployment in less time with reduced cost and maximum efficiency.From one perspective, it seems to be nothing new as it approaches concepts already built and established however from another perspective, cloud computing is something complete new as it develops ideas on ho w we deploy, update, scale, invent and maintain our applications over a huge network. Over the last few years, virtual machines have become the standard deployment object. We have seen how people connect to remote computers using built-in applications. As we can see, it further improves the flexibility as the system is total pendent on the host.For instance, a person can rent a computer for a few hours being provided the authentication by host. This way, many people can have access to powerful systems for less cost without needing to upgrade hardware to enhance their systems. Figure 1-2 shows a typical remote desktop connection. This shows how cloud computing has revolutionized over the years and been made better. Cloud computing promises us in the future to be able to access computers through web browsers with reliability and an affordable cost. Keywords? on demand deployment, flexibility, fertilization, hypothesisFigure 1-2 (a typical remote-desktop connection) Infrastructure Prog rammable Infrastructure In the past, developers would identify how the various component of application would be managed, secured, modified, interconnected, and deployed. Now a developer would be able to use a Cloud Provider's API to manipulate the application on the go and not only that but to manage tremendous work load changes. Consider this analogy: A Java developer creates and deletes thread to do multiple activities at the same time however now developers can do the same but modify the application dynamically giving them power to accommodate accordingly.To make the best out of cloud computing, a developer must be an architect being able to create a self-logging and self-expanding application for best user experience. Infrastructure as a Service (alas) alas is one of the fundamental service models of cloud computing. It provides computing resource in a brutalized environment, â€Å"the cloud†, usually through a public network like the Internet. It includes attributes suc h as virtual server space, network bandwidth, IP etc. A hypothesis such as Java VIM creates virtual machines and/or allows you to connect to one over the internet.Platform as a Service (Pas) Pas is another fundamental service model of cloud computing. In these models, the provider delivers services such as an operating system, an executable environment (programming environment), database server etc. Application developers can run and develop their programs on this platform service without the cost of buying additional hardware. This is extremely useful to the ones whom cannot afford the luxury of powerful systems and complexity of managing hardware. Software as a Service (AAAS) AAAS is Just another fundamental service model of cloud computing.

Advantages and Disadvantages of Using Positive and Negative Reinforcement †Management Essay

Advantages and Disadvantages of Using Positive and Negative Reinforcement – Management Essay Free Online Research Papers Advantages and Disadvantages of Using Positive and Negative Reinforcement Management Essay I will be discussing the two types of operant conditioning which are positive reinforcement and negative reinforcement. I will attempt to list the advantages and disadvantages of using either and briefly touch on extinction which is the lack of use of either positive or negative reinforcement. There are four types of operant conditioning namely positive reinforcement, negative reinforcement, punishment and extinction. According to Skinner’s terminology, any form of incentives such as goals and rewards may be referred to as positive reinforcers and the receiving of the reward or achieving the goal is termed as positive reinforcement (Skinner B.F., 1969). In positive reinforcement, a particular behaviour is strengthened by the consequence of experiencing a positive condition (mcli.dist.maricopa.edu/proj/nru/opcond.html). Positive reinforcement is effective and largely used for two separate reasons. Firstly, it is one of the most powerful techniques available for the direction or motivation of the actions of other people. The second reason which is more philosophical is the versatility of the concept of reinforcement as an explanation of behaviour (Walker. S, 1975). In other words, the question is why do people behave the way they do? The answer will be that it is because they (people) are reinforced for it (Walker. S, 1975). Many companies employ the use of positive reinforcements to increase productivity, decrease absenteeism and workplace accidents. One company tried holding lottery draws ever month and they noticed a significant consistency in attendance. A construction company offered incentives such as a buffet end of each month if the workers maintained an accident free record. True enough, the accident free record was maintained for a good number of months (Mazur J.E.,1986). When positive rein forcements are used, the desired outcome is that the behaviour is reinforced. Subjects understand that the behaviour is desirable and will tend to repeat it for the rewards. In the negative outcome, subjects may take the rewarding for granted. They may repeat the behaviour with the intention of receiving more of the rewards and not understanding that that behaviour is desirable or they may deem the rewards as part and parcel of things. That is that the education part has failed. Some examples of these negative outcomes may be employees who get verbal praises for everything they do, think that it is all lip service. There is no real intention to compliment them for their good work. Another would be a young child plainly doing things to curry praises (Strain P.S., Joseph G.E.). In a similar fashion, a negative reinforcer is a stimulus one would desire to avoid. The act of escaping or avoiding a negative reinforcer is termed as negative reinforcement. Disincentives are punishers. There is a natural tendency to put punishments under the wing of negative reinforcement. However under the definitions of operant conditioning, negative reinforcement is the strengthening of a particular behaviour by the consequence of experiencing a negative condition (mcli.dist.maricopa.edu/proj/nru/opcond.html). Punishment in the operant conditioning sense is to weaken a particular behaviour as a consequence of experiencing a negative condition. Negative reinforcement is used commonly for education or reform. The use of fines, imprisonment is one such example of the use of negative reinforcement to warn of the negative consequences of associating with social ills. Skinner (Skinner,1953) and many others prefers the use of positive reinforcement to encourage good behaviours and do away with the social use of punishment altogether. Advantages of the use of negative reinforcement would be of course ideally the cultivation or strengthening of a desired behaviour after receiving the negative reinforcer. An example would be that an employer informs his or her employee that their work requires some polishing up to meet the customer standards. The employer may go on further to explain that the customer is rather demanding and any negative feedback will tarnish the credibility of the employee. The desired response would be that the employee strives to perform better. Disadvantages of using negative reinforcement would be when the desired behaviour is not achieved. For instance a child was punished for strewing his toys on the floor by facing the wall and repeatedly saying he will not throw his things on the floor. He kept repeating the act and undergoing the punishment but he never understood why he should not leave his things on the floor. That is a negative outcome . Different organisations may choose to employ different styles of reinforcements or non at all. Commercial and non-commercial organisations may also use different approaches. One may use positive reinforcements to encourage repetition of the desired behaviours. Others may use negative reinforcements to discourage behaviours that are not in line with their policies. There are slight differences in how public and private schools educate their students. In general, schools tend to use negative reinforcements on rule breaking students as a method to educate them. The typical examples are verbal reprimands, being sent out of the classrooms, detentions, etc. There is an element of shame within these punishments which is intended to allow the students to discover how to behave well. Critics oppose to the use of negative reinforcements in schools and largely recommend the use of positive reinforcements. Negative reinforcements are used and positive reinforcements are easily ignored due to the strong cultural ethos that encourages the use of punishments. The use of punishments is effective ninety-five percent of the time. The remaining students are those with challenging behaviours who do not respond to traditional forms of punishments. So unless figures show otherwise, Skinner’s hope that positive reinforcement be used totally cannot be easily realized and punishments will still be the tool employed by schools to educate and to deter wayward behaviours. The proverb â€Å"spare the rod and spoil the child† explains the continued use of such traditional methods of educating (Maag J.W., 01-01-2001). It is a good point to emphasise that the discussion is on the use of negative reinforcements on students to shape a desired behaviour and not on punishments. Punishments here are merely the reinforcers or the tools of reinforcement. Maag suggests using new approaches to handle challenging students which are effective reinforcers which are ideally negative but wi thout the use of punishments (Maag J.W., 05-01-2001). Commercial organizations depending on situations, use positive and negative reinforcements. Although there is no premeditated use of scheduled reinforcements on encouraging desired behaviours and discouraging undesired behaviours, some managers do enforce them. As more managers understand the needs for better and efficient management styles, they also understand that subordinates seek job satisfaction. Job satisfaction can be achieved in many ways such as pay rises, day offs, or even simple words of encouragement, praises and recognition (Zielinski D., 05-01-2001). More than often the occasional verbal praises for a job well done does a lot to make an employee feel appreciated. Researches have shown that positive reinforcements increase the attendance of workers, improve their performances and also increase safety awareness. Negative reinforcements are sometimes used on the occasional lackadaisical employees. Romero and Kleiner believes that the use of positive reinforcements is a management concept, and that it should be used in the workplace both domestic and international (Romero J., Kleiner B.H.). Research was done on people in several countries on the relation between personality and motivational traits and work related attitudes. It is found that the use of positive reinforcements greatly motivated workers and the whole economy of the country gained greater growths. In bad management styles, employees are swiftly reprimanded for failing to attain their employers’ standards and are often not complimented for completing their tasks excellently. Many are so accustomed to these practices that they begin to become complacent due to the lack of recognition and rewards. The failure to positively reinforce an employees’ good performance which is a form of extinction may discourage them from giving more than they should since no recognition or rewards will be given for it. Much research has been done on operant conditioners. More people are aware of the existence of positive and negative reinforcements. More are championing the use of positive reinforcements to increase productivity, attendances, safety awareness, job satisfaction and to reduce absenteeism and accidents. Depending on the situations, positive and negative reinforcements when applied strategically can be effective in strengthening a desired behaviour. Strategic application of reinforcements would mean the use of reinforcements at intermittent schedules such as at fixed ratios or variable ratios combined with the understanding of what motivates their subjects of interest. Doing away with punishments may be the ideal case for Skinner, I believe that it is not possible to do away. However we can reduce the use of punishments when positive reinforcements are adequately and effectively employed. The advantages of the use of positive reinforcements are highly explanatory of itself.

Chinese Legal System essays

Chinese Legal System essays One of the most interesting forces in modern world trade and globalization is China. Indeed, while its presence in the world market is not a recent phenomenon, the globalization effect has necessitated recent changes in Chinas trade system, specifically in the private enterprise sector. In this, the greatest challenge China faces is realizing its goal of encouraging enterprise and trade while at the same time retaining the centuries-old traditions on which the country has historically thrived. China appears to be thriving on several arenas of the global trade paradigm. In terms of imports, the countrys membership in the World Trade Organization since 2003. In the same year, it was listed as the third largest commodities importer. This, along with the countrys willingness to open its policies to create a more friendly environment for foreign traders, has rapidly expanded the countrys total foreign trade volume. However, the country also faces several challenges in terms of its WTO membership commitments. One of these is its non-market economy status. This means that within the first 15 years of its membership, China is obliged to calculate its product prices in reference to other countries, rather than on the basis of its own production costs. This could mean significant losses in the countrys exports. Another challenge is the safeguard mechanism for specific products. This means that any member country could request a consultation with China if one of its export product prices increased dramatically. In terms of its domestic products, China also appears to experience a period of great prosperity. Several factors are responsible for this. These include political, cultural and economic factors that affect domestic product manufacture. A political and cultural factor relates to the improvement of private enterprise climate via offering membership in the Communist Party of China to ...

DEsigning a Psychology experiment , 1000 word maximum report Essay

DEsigning a Psychology experiment , 1000 word maximum report consisting of an hypothesis and a method section - Essay Example 3. METHODOLOGY This project requires cause and effect hypothesis testing and therefore the design chosen is an experimental design (Srinagesh, 2006), with a quantitative research methodology. 3.1 Participants (Sample) The sample for this research will consist of two groups of college students. The sample will be drawn from among college students. The sample will consist of 40 college students in all. Twenty of these will be those whose parents have been divorced while twenty will be those whose parents are both alive and living together. In order to control the variable of gender, each group of participants will be composed of ten males and ten females. The students will be approached along with a briefing letter about the experiment and they will be asked to sign an informed consent form if they are willing to participate in the research. 3.2 Variables The independent variable in this study will be the divorced or not divorced status of the participants’ parents while the dep endent variable will be the scores obtained on the questionnaire titled: ‘Student readiness Inventory’ (ACT, 2011). 3.3 Research Design and Method This experiment involves hypothesis testing and is based on quantitative methods. ... oups, one will consist of children whose parents have been divorced and the other will consist of children whose parents are living together, therefore, an independent groups design fits the aim of the study. This design will also remove the threats to validity due to order effects (Brian, 2002). This methodology was chosen because the nature of the study is experimental rather than exploratory. Hypothesis was devised after some quick review of literature and theory. It is expected that the null hypothesis will be rejected. 3.4 Research tool/ Instrument After reviewing a considerable number of studies that attempted to focus the effects of divorce on academic achievement, it was decided that questionnaire be used as research tool (Anderson & Taylor, 2008). The ‘Student readiness Inventory’ was selected to be used as a research tool. Student Readiness Inventory is a questionnaire that was developed by a non-profit organization called ‘ACT’, in order to identi fy the at-risk students in the field of academics. The rationale for selecting this inventory is twofold: first, if Grade Point Average would have been used to gauge academic success, it would not have taken into account the psychosocial factors that affect academic performance in children of divorced couples. Secondly, the Student readiness inventory was preferred over Grade point average because different individuals’ parents got divorced in different years. Tracking down the Grade Point Average of the students in the year following the divorce would have been a challenging task. Therefore, it was decided to run the Student readiness inventory, which is a short inventory and is very easy to score. 3.5 Data Analysis Descriptive statistics will be used to analyze the data. According to Kazmier (2004),

Performance Management in Organisations Essay Example | Topics and Well Written Essays - 3500 words

Performance Management in Organisations - Essay Example The paper offers a thorough analysis of the performance management system (PMS). It provides the information about vital components of the PMS, namely, its objectives, stages of development, setting of company goals and standards, working on performance appraisal, communication, and training. The author proves that an effective performance management system enables an organisation to set targets, monitor implementation, and evaluate the performance of its employees. It provides a platform to the management for communicating with employees in order to evolve ways and means to increase productivity and efficiency of the organization as a whole. The research shows that a successful PMS facilitates an effective dialogue between employee and supervisor to enhance individual performance. In particular, it gives managers and supervisors opportunities for giving positive reinforcement to employees. In order to be effective and acceptable, performance appraisals should be fair, open, and posi tive with developmental objectives. The unique part of the work is that the notion of the PMS is studied not only theoretically, but also through the comparison of the PMSs of two institutions,a state secondary school and a haulage firm. The author creates performance appraisal sheets for measuring teachers' and managerial work. Appraisal parameters of teachers' performance are academic knowledge and communication skills, ability to prepare lesson plans and to deliver them. Appraisal parameters of managerial work are managerial, operational, administrative, and decision-making skills.
