Organizational Behavior Concepts Essay
Organization behavior concepts are the study and identification of management activities and strategies that provide employee effectiveness through understanding of the complex nature of individual, group and organization process. Organization behaviors concept draws from variety of disciplines including psychology and sociology to explain the behaviors of people in the company. Therefore concepts are methods or formulas followed to govern the individual or group productivity of the company and the effectiveness of leadership in an organization. Since more companies are looking at how to automate and improve their services, they are creating self-services opportunities for employees and streamlining application based process so as managers can focus on key issues while performing their task. This has brought about a great success to software companies for the rise in demand of their products and services. IBM being a Worlds premier single source provider for multi-vender IT solutions has a great success that encouraged more planned concept to enhance the corporation meet its target and consumers need. Human resource practices Human resource management has become one of the most important aspects of running a company. It has been realized that having a competent and a motivated workforce can help a company create a competitive advantage which other companies may find hard to replicate in the market. Therefore there is need for the company to take bold step in order to address issue of hiring and retaining a competent work force. It will begin by changing the style of leadership from the authoritative rule in order to give the workers more freedom to make their own decision as pertains to the operation of the organization. But them most important thing is for the organization to come up with a human resource plan that will be integrated in the overall growth strategy. A strategic human resource plan will define issue on hiring, retaining, training and development of the workforce in order to maintain a competitive workforce. According to the famous McGregorââ¬â¢s theory x and y, in x mangers assume workers are lazy and irresponsible and require constant supervision and external motivation to achieve organizational goals. The theory y managers assume workers want to work and can direct and control themselves. In advocating for theory y, managers who allow opportunities for individual challenge and initiative and who encourage participation would achieve superior performance. (Glyn 1999) Through the years, IBM has consistently practiced and emphasized the development of human relation to achieve individual goals. Through practice, The Company has managed to achieve notable achievements in attraction of new and retaining current customers. IBM has given a great consideration in strengthening relationship between the customers and the company which have brought about a great growth in sales both locally and internationally. IBM has a planned strategy to be followed by leaders and employees that avoids differences in interpretation of issues and ideas that may favor the relationship between them. The set rules govern all issues addressing any human relation in the company therefore saving money and time. The IBM has well organized bureaucratic strategies which have eliminated variability in result. When new employees are employed, they come in with different skills, experiences and goals, the rules themselves are standardized so that the personnel changes do not disrupt the whole companyââ¬â¢s human resource management. When each individual employs personal skills, ideas and goals they may not rhyme and this may cause difference in management and definitely misunderstanding between individuals or group. Therefore this has been fully put in to consideration and has helped the company achieve in the competitive market. This have also helped the company position faster specialized skills eliminating many subjective judgments by managers where rules and regulations are established properly and have a set method to follow to avoid different individuals employing their rules hence causing conflict between the concerned parties. This has gone hand in hand with training of leaders and employees on the set rules to standardize their performance and reinforcing human resource department. IBM has currently been able to achieve the right segment in the market which has made it possible for the company to enter the main stream of the market. This was made possible close interaction between the company and customers through entering into contracts with local and international companies raising the need for close relationship and work together to fill the demand and high sales volume. Motivation Motivation is the force or impetus behind behavior and actions. This energizes behavior and directs behavior towards a goal. In IBM, managers are always expected to create a desire of working to employees by creating conducive environment and a favoring atmosphere for working. IBM has been advocating the use of reinforcement by rewarding. An attractive object or event is supplied as a consequence of a particular work done perfectly. According to behavior approach to motivation, managers have an understanding of employees motivation which begins with careful analysis of incentive and rewards that are present in the company. These incentives are like privileges and money. Its always managers responsibility in IBM to identify behaviors that need to be reinforced like outstanding performance, punctuality, neatness and completion of work. The managers are always alert to notice the desired behavior occur. Occurrence is always accompanied by reinforcement. An employee who shows an improved performance is rewarded. The principle is that reinforcement strengthens behavior and gives that exact behavior a chance to occur again. In IBM, cognitive approach state that behavior is determiner by over thinking and not reward or punishment, it is initiated and regulated by mental process and not external events. Managersââ¬â¢ role in motivation is to help workers develop on curiosity and help them develop methods for searching for information. In IBM, workers are trained to be intrinsically motivated. The social working approach is an integration of cognitive and behavior aspect. This theory sees motivation as a product of two main forces, individual expectations of success in a task and vicarious experience. Individual expectation of success is determined by personal effectiveness, personal effectiveness is also called self efficiency and refers to personal confidence. The manager should empower employees to become competent in performing a task. If the empl9oyee knows that he will succeed in doing a task, then his motivation will be high. Vicarious experience constitutes the observation of other workers and compares performance. If the worker discovers that his performance is poor, he may lose his sense of competence. In this respect the manager should the employee to keep up with level of performance of other employees so that motivation is highlighted. Though intrinsic motivation comes from the worker, is referred to as ego involvement. This results from employees identification with desired goal. The employee is fully involved in learning a task. Managers task is to empower the employee to identify with that work if the need for confidence is made. Competence means ability to perform) Ability to master every a task also mean competitiveness. In a task every employee has interest and desire to perform confidently in a companyââ¬â¢s task. Managersââ¬â¢ role is to discover how to empower the employee to achieve. In IBM corporation managers assist the employee by providing them with opportunity to become competent and help them to avoid failure. They achieve this by giving them a task that they are intellectually capable of achieving. When an employee is successful in performing a task, his self concept is enhanced and this gives great respect to the company. In IBM Corporation, motivation is displayed in personal goals and that very many motives are personalized depending on what the company wants to achieve. These personalized goals determine individual level of aspiration. Due to continued success, there is always an aspiration to modify and develop companyââ¬â¢s strategies that would enhance better performance for both managers and employees. Organizational structure The IBM Corporation has a well planned leadership strategy which is an important factor that determines the viability of an organization operation. Good leadership is responsible for growth of the organization while unplanned leadership is responsible for drift in an organization. Planning mode of leadership, there should be a procedure to follow and that will help in determining the weaker points in the leadership therefore avoiding drift. Management is the most important factor that determines the viability of any organization operation. Good management is responsible for growth of the organization while bad managements can be held responsible for collapse of organizations. The IBM Corporation is currently being held at ransom by the kind of leadership structure. There are many kinds of leadership that are used in running organizations depending on the kind of the organization. In IBM the authoritative kind of leadership in the organization has been responsible for some of the problems like making of decision for the organization. In this regard it is clear that there is a problem in making decision since they are made from the top and the Chief Executive Officer (CEO) has to be consulted before any decision is made despite the fact that there are other people in the organization who are more experienced in this work. Authoritative leadership holds the organization to the management and it discourages innovation since the CEO has to be consulted on all matters regarding the operation of the organization. The CEO acts to provide guidance for the organization and one of the duties of CEO are to delegate duties of the office. In this regard, the CEO has to give some of the authority to other managers in the organization in order to decentralize decision making process. Rise in the interest in developing people through out the organization could be attributed to a number of factors. In IBM, employees are taking broader ranges of responsibility, managers, in particular are faced with a completely new environment. They are responsible for more people often worked in strategy-oriented companies and therefore, the skills and competencies that previously served them well no longer work. They have to make fundamental changes and come up with more planned productive strategies to avoid drift. (Jackson 2005) Advertisement is another most important component that characterizes the operation of IBM Corporation in the market since it raises the awareness of the consumers about the availability of the products in the market. Therefore a well planned advertisement is an important component that helps a company to penetrate the market especially when introducing a new product. Lack of a planned advertisement may have limited growth of the company which in return may cause losses in the company. Keeping in mind that the company is operating in a very competitive market, there is a need to plan strategies to follow to avoid any sort of dissatisfaction to the customers which may lead to a drift. IBM Corporation market has a wide scope which comprises of many factors. These factors are essential for the maintenances of businesses competitiveness of the services and goods being delivered by the company in the market, either in goods or services, the IBM marketing team has the privileges of collecting relevant data from its market target which quite fundamental is its goods and service improvements that enable the maintenances of high competitiveness in the international markets. (Michael 1993) When introducing a new technology in the organization, IBM Corporation has a proper planning that enables the employees adapt and learn much quicker because lack of proper planning can cause a drift that may be hard to recover. The corporation has set strategies to be followed and adequate training to lessen the risk of taking more time omitting other duties. The introduction of new technology in a company has caused a drift in many companies for most managers command employees on making use of technology that they are not used to therefore causing alternation of formally followed rules. Example, if the company has been using paper work may in accounting department, introduction of computers may alter the set road map because of training and mental ideas that one is supposed to do more than before therefore causing a drift. To avoid this, the IBM Corporation has set a long term planning and informs the employees in advance so as they may be prepared physically, mentally and psychologically to avoid more excitement on introduction of the new technology. Conclusion If the company fails to have a proper planning, is likely to be faced by many challenges. One of the biggest challenges the company is likely to face in the structure of the business in the sense that will be difficult to change or recover. The managers may work hard but the competitors may continue enjoying great profits due to lack of proper management strategy. Management should be well planed and strictly followed to know the weaker parts of management. A well addressed strategy in all areas of leadership will enhance a greater interest in the company, workers participation and productivity. In IBM, the relationship between managers, employees and consumers is valued and put in to great consideration, this is encouraged because it gives a good reputation to the company hence increasing its business achievements world wide.
Abrasive Water Jet Cutting Report Engineering Essay
Up until about the mid twentieth Century the bulk of production relied on ââ¬Å" two traditional procedures of forming and machining ( Tlusty, 2000 ) . Forming is the procedure of altering the form of the whole work piece, whereas machining removes merely certain, and desired countries. Whilst these cardinal procedures still form the really anchor of contemporary production, there has besides been the demand for new procedures to be developed. The traditional procedures, as highlighted above, have a figure of built-in restrictions which limit their application to industry. In the instance of conventional machining procedures, a crisp film editing tool is used to organize a bit from the work by shear distortion. This consequences in the formation of high forces together with the corresponding mechanical energies. Together with this are a figure of extra jobs that can originate. Due to sum of energy required to transport out the operation, a physique up of unwanted heat can happen, which frequently leads to deformation of the work piece and surface snap. In certain instances, the forces introduced by the procedure are highly high and in order to procure the work piece considerable clamping forces are required ; this excessively can take to deformation. Together with these restrictions, the development of stuffs with belongingss of high strength, high hardness and high stamina has driven the debut of untraditional machining methods. Nontraditional machining ( NTM ) methods have been developed since World War II in an effort to turn to machining demands which can non be carried out by conventional methods entirely ( DeGarmo, Black & A ; Kohser, 2003 ) . NTM methods provide the ability to machine: Complex geometries ; Components with an first-class surface coating ; Delicate constituents, which otherwise would non defy the clamping forces ; and Brittle stuffs or stuffs with really high hardness. There are four types of untraditional procedures ; classified harmonizing to the principle signifier of energy used to consequence stuff remotion. These include: mechanical, electrical, thermic and chemical. One procedure which falls into the mechanical class is scratchy H2O jet ( AWJ ) film editing, and will be the focal point of this study. First, and prior to discoursing AWJ, the procedure of H2O jet ( WJ ) film editing will be introduced.Water Jet Cutting ( WJC )Water jet film editing, which is besides known as waterjet machining and hydrodynamic machining, was foremost developed in 1968, followed by the first commercial system in 1971 ( Zhong & A ; Han, 2003 ) . Through the usage of a all right, hard-hitting, high-speed watercourse of H2O directed at the work piece ( surface ) , a cut is created, as illustrated in figure 1 below. In order to bring forth the all right watercourse of H2O, a nose with an gap ( opening ) typically in the order of 0.1 ââ¬â 0.4mm is used ( Groover , 1996 ) . Together with this, runing force per unit areas of around 400MPa and above are used to supply sufficient energy for cutting to be carried out. Furthermore, the fluid of the jet can frequently make 900m/s and the cardinal procedure parametric quantities include: H2O force per unit area, opening diameter, H2O flow rate and the working or ââ¬Ëstandoff ââ¬Ë distance between the nose and the work piece. Figure 1 ââ¬â Schematic of WJC Process ( Groover, 1996 ) As the typical film editing force per unit areas as mentioned are required, a hydraulic pump is used to supercharge the fluid. The fluid is so passed through a valve, which regulates the flow rate in order to accomplish the optimal cut. The concluding phase of the fluid is to go through through the nozzle opening and impact the work piece surface from a controlled tallness.Procedure ParametersThe stuff from which the nose is made is doubtless the most of import parametric quantity in footings of procedure control ( as this greatly determines the opening diameter ) . The nozzle unit comprises of a unstained steel holder, together with a gem ; normally sapphire, ruby or diamond. Of these stuffs, diamond lasts the longest but is the most expensive. Recent progresss in the production of man-made sapphire offer this stuff as non merely the most cost effectual solution, but besides due to other advantages excessively. Man-made sapphire can be machined moderately accurately and besides has a high opposition to have on. The most common causes of nozzle failure are due to sedimentations come ining the fluid watercourse, therefore underscoring the demand for high degrees of filtration of the fluid prior to pressurisation, to cut down nozzle wear. With proper nozzle design a tight, coherent waterjet can be produced and maintained really accurately. When transporting out the cutting procedure, both the opening diameter and the ââ¬Ëstandoff ââ¬Ë distance must be closely monitored to keep a changeless deepness of cut. As the nozzle wears, compensatory alterations in the draw tallness must be made. Although existent draw distances vary from beginning to beginning, distances in the order of millimeters are normal ; normally around 0.25 ââ¬â 3.5mm.WJC: Advantages and DisadvantagesWJC offers many advantages over conventional machining methods. This machining procedure provides the ability to cut stuffs without firing or oppressing the work piece. Furthermore, no important heat is generated, therefore, deformation is minimised and in some instances, eliminated. Unlike machining or grinding, no dust is produced ensuing in small environmental pollution. Other advantages include minimum material loss and easiness of mechanization when used with numerical control and industrial automatons. Whilst such advantages exist, one of the chief disadvantages to H2O jet film editing is that there are merely a limited figure of stuffs that can be cut economically ( MTU, 2009 ) . Although it is possible to cut tool steels utilizing this procedure, the provender rates have to be greatly reduced and therefore the edged clip increased. This, in kernel, consequences in a high cost procedure. Such stuffs that can be cut utilizing the H2O jet procedure include: plastics, fabrics, complexs, floor tiles, rug, leather and composition board.Abrasive Water Jet Cutting ( AWJC )To allow the film editing of difficult stuffs such as ceramics, metals and glass, together with those softer stuffs, for illustration froth and gum elastic, the WJC procedure requires the add-on of scratchy atoms, therefore organizing the scratchy H2O jet ( AWJ ) cutting technique. In a similar mode to WJC, the procedure is carried out utilizing a high-pressure, high-speed watercourse of H2O ; nevertheless, the discrepancy being that an scratchy stuff is dra wn in by a vacuity, which is created by jet watercourse. Figure 2 ââ¬â Schematic of AWJC Process ( Meier, Louis & A ; Pilot, 1995 ) Figure 2 illustrates a typical apparatus for transporting out scratchy H2O jet film editing. It can be seen that this follows closely the agreement of WJC equipment, nevertheless, with the add-on of a twosome of cardinal characteristics ; viz. the scratchy eating system and a ââ¬Ëcatcher ââ¬Ë , which is required to protect the environment from the high energy jet.Procedure ParametersAs antecedently highlighted, the WJC procedure depends on a figure of parametric quantities. Whilst many of these are movable to the AWJC procedure, there are besides add-ons to reflect the alteration in cutting method. Momber & A ; Kovacevic ( 1998 ) present a list of such parametric quantities, which can be seen in figure 3 below. Figure 3 ââ¬â AWJC procedure parametric quantities ( Momber & A ; Kovacevic, 1998 ) Although it is by and large accepted by many writers including JankoviAâ⬠¡ ( 2008 ) that the nose or opening diameter is the cardinal film editing parametric quantity, in the instance of AWJC, the abradant besides has considerable influences on the quality of the cut achieved. A choice of the parametric quantities as listed above has been explored in the subsequent subdivision, followed by an overview of the entire system control in the subdivision thenceforth.Procedure Parameters: Overview of Observed InfluencesThe most of import parametric quantity, by far, is the orifice diameter. The deepness of cut is straight relative to the opening diameter ; nevertheless, making an optimal point at big diameters. Although related to pump force per unit area, figure 4 below clearly illustrates this point, demoing how the deepness of cut varies with opening diameter. Figure 4 ââ¬â Influence of opening diameter on the deepness of cut ( HeI?ling, 1988 ) Another parametric quantity that is closely linked to the opening diameter is the focal point diameter. This component of the cutting equipment determines the strength of the watercourse, therefore holding a direct consequence on the material remotion rate as shown by figure 5 below. Figure 5 ââ¬â Influence of focal point diameter on the volume remotion rate ( Blickwedel, 1990 ) The focal point diameter is of import non merely in footings of the volume remotion rate but besides the deepness of cut. Figure 6 below shows how the deepness of cut is besides determined by this parametric quantity ; diminishing as the focal point diameter additions. The lessening in deepness of cut following an optimal point is realised by Himmelreich ( 1992 ) and has been attributed to high grades of turbulency. On the other manus, a peculiarly little focal point diameter gives rise to particle hit and clash, giving an inefficient procedure. Figure 6 ââ¬â Influence of focal point diameter on the deepness of cut ( HeI?ling, 1988 ) Of the cutting parametric quantities listed, the crossbeam rate can be said to hold the greatest influence on the film editing procedure, followed closely by the draw distance. Both of these parametric quantities are controlled by machine design and therefore are bound by the makers ââ¬Ë specification. Figures 7 and 8 overleaf illustrate the influence of both the crossbeam rate and draw distance. It can be clearly seen that the deepness of cut lessenings as the crossbeam rate additions, following closely that of a squared map. However, on the other manus, the relationship between the draw distance and the deepness of cut is moderately additive ; with the deepness of cut decreasing as the draw distance additions. A big figure of scratchy stuffs are available for usage in AWJC. Typically these are loosely categorised as either oxides or silicates and there are, in a similar manner to the whole procedure, many parametric quantities that determine the features of an abradant. Figure 7 ââ¬â Influence of crossbeam rate ( left ) and standoff distance ( right ) on the deepness of cut ( Blickwedel, 1990 ) Whilst it is hard to state precisely which parametric quantity has the greatest influence on the procedure, it is clear that both the hardness of the stuff together with the atom form and size, need consideration. Typical hardness values vary from 30 HV for Cd up to 200 HV for B carbide ( Kriegel & A ; Palmour, 1961 ) . Figure 8 shows the influence of both the atom form and size, whereas figure 9 overleaf high spots the significance of the mass flow rate of abradant on the deepness of cut achieved. Figure 8 ââ¬â Influence of abradant ( atom ) diameter and size on the deepness of cut( Ohlsen, 1997 ; Oweinah, 1989 )Figure 9 ââ¬â Influence of scratchy mass flow on the deepness of cut( Oweinah, 1989 )Abrasive Water Jet Cutting: Associated ProblemsIt is clear from the old subdivision that there are many parametric quantities that have an consequence on the AWJC procedure. If such parametric quantities are non carefully controlled, so the efficiency of the procedure decreases along with the quality of the machined portion. Some of the associated jobs are presented in table 1.Problem and definitionParameter ( s ) affected byConsequence on constituentTaper. This characteristic arises due to a difference in the breadth of the cut at the top surface and the bottom surface and is given as a ratio ( besides flank angle ) . Abrasive mass flow rate Focus diameter Standoff distance Trave rate This characteristic determines the dimensional truth of the portion. Initial Damage Zone. Abrasive atoms impact the surface at normal angles doing craters and abrasive-wear paths. Standoff distance Focus diameter ( Abrasive atom size ââ¬â composite stuffs ) Some fictile distortion can happen. Change ( debasement ) in surface roughness/waviness. Trave rate Focus diameter/length Abrasive mass flow rate Abrasive atom size/type Surface belongingss of stuff are non as desired. Decrease in fatigue life of cut stuff due to check formation. Abrasive atom size Fatigue life reduced. Onset of stress-corrosion snap. Surface indurating due to procedure. Abrasive stuff Variation of hardness at distance from cut. Micro-structural alterations: Surface checking Phase alterations Abrasive-particle fragment implanting Delamination in composite stuffs Burr formation Assorted Assorted Table 1 ââ¬â Problems that can originate when transporting out AWJCAbrasive Water Jet Cutting: Control MethodsTo guarantee such issues as those mentioned in table 1 do non happen, accurate control mechanisms must be in topographic point. There are many supervising mechanisms in topographic point today, some of which have been briefly described below. These methods lead to the control of the cutting procedure ; nevertheless, this is non automated in these instances. Jet-Structure Monitoring ââ¬â used to command focal point diameter. Diameter of entry to concentrate point monitored to reflect alterations of focal point diameter. Wear rate can be monitored utilizing this method. Acoustic Sensing ââ¬â used to supervise overall focal point conditions. System based on the fact that a alteration in the focal point conditions ( orifice diameter and concentrate diameter ) affects the sound generated by the system. Figure 10 ( overleaf ) illustrates the difference between the acoustic form of a new and worn nose. Inductive Measurement ââ¬â used to supervise scratchy H2O jet speed. Method requires magnetic scratchy atoms. Abrasive jet is encircled by two little spirals, which is connected to a detection system. When the atom passes through the spiral, a little electric signal is created and the velocity determined. Figure 11 shows the typical apparatus of equipment, in this instance. Besides, laser systems similar to the above, nevertheless utilizing light pulsations alternatively. Material-Removal Visualisation ââ¬â used to supervise material remotion rate. In a similar mode to Acoustic Sensing, noise of cut is monitored. Frequency of signal indicates type of cut ( inter-granular/trans-granular failure ) and therefore determines the efficiency of the cut. Workpiece Reaction Force ââ¬â used to supervise deepness of incursion and surface topography. Empirical expression that takes into history all input parametric quantities excepting the crossbeam rate. Can go a force-feedback system ; leting parametric quantities to be modified to cut down the force. Figure 10 ââ¬â Acoustic form for new and worn nose ( Kovacevic & A ; Evizi, 1990 ) Figure 11 ââ¬â Initiation monitoring system ( Swanson, Kilman & A ; Cerwin, 1987 ) The above systems offer a chiefly generic attack to system patterning and supply small or no feedback. Modern control of AWJC makes usage of an intelligent monitoring and control system, which has full feedback capablenesss. Such an illustration by Srinivasu & A ; Babu ( 2008 ) utilises two systems: machine-vision based monitoring and intelligent control. The vision based portion monitors the size of the concentrating nose and the control system, which uses unreal nervous webs, continually modifies each parametric quantity to accomplish the best cut. A full analysis of this system is nevertheless beyond the range of this study. Abrasive Water Jet Cutting: Overview of Applications The applications of AWJC are huge, covering industries such as aerospace, automotive and electronics. It is beyond the range of this study to cover any peculiar country in important item ; nevertheless a few illustrations have been given below. Traditional and perchance even simple procedures have been ignored, and alternatively this study concentrates on a few non-standard applications.Meat CutingOne application of AWJ cutting is in the meat processing industry. Harmonizing to Wang & A ; Shanmugam ( 2008 ) , meat film editing is an of import activity and factors such as the cost, the presentation and sliting all need consideration. In this instance, salt is used as an scratchy and really good quality cuts, when compared to conventional film editing and even plain H2O jet film editing, can be achieved.Crunching Wheel ProductionThis illustration is slightly different to all other applications of AWJC as in most instances a through cut is desired. Axinte et Al. ( 2009 ) present an turn ing application, whereby crunching wheels are shaped harmonizing to their specification. Whilst this is considered a niche market, the writers conclude that AWJC has non merely the economical but besides proficient advantage for fabrication of this constituent. Assorted determining operations can be carried out, ensuing in such merchandises as figure 12 below. Figure 12 ââ¬â Examples of crunching wheels manufactured utilizing AWJC ( Axinte et al. , 2009 )Polishing of SteelAnother application of AWJC is smoothing, and in peculiar steel. Yan et Al. ( 2008 ) describe this application, foregrounding that electrical-discharge machining ( EDM ) is normally used for mold production. The writers province that EDM typically leaves a brickle recast bed ; taking to the application of this smoothing method. When compared to traditional methods, AWJC has a lower scratchy ingestion and recycling is improved. In this illustration the abradant is SiC and to help the procedure is covered in wax. This consequences in a much finer surface coating.Complexs ProcessingThere are many applications of AWJC in relation to complexs treating as in some instances traditional single-point film editing procedures can non be used. For illustration, Komanduri ( 1997 ) describes that it is non possible to machine SiC whisker-reinforced aluminum oxide with a single-poin t film editing tool ; nevertheless, that it may be possible to determine by crunching. Whilst some complexs can be approached in this manner, rapid tool wear is experienced and therefore the debut of AWJC is a much better method.DecisionThe old subdivision provides a figure of non-standard illustrations where AWJC is being used. Although these give a general overview, AWJC can besides be used for alternate machining procedures, such as: milling, turning, piercing, boring ( although non level bottomed holes ) and thread film editing ( Momber & A ; Kovacevic, 1998 ) . Although such procedures as above can be achieved, in a similar instance to before there are many parametric quantities that need to be monitored. This is possibly a downside to this untraditional method unless modern control methods are introduced. Further disadvantages of the procedure include the fact that degradable stuffs can non be cut and the surface coating of machined constituents relies to a great extent on the procedure. Possibly the most important consideration of using this procedure is the apparatus cost ; which can be highly high in certain instances. One other disadvantage is the noise created by this fabrication procedure. Although, as highlighted above, there are many factors that control the procedure its application to modern industry has grown significantly since its debut in the 1970 ââ¬Ës. This has been driven chiefly by technological promotions, therefore leting this procedure to be developed, but besides due to of all time germinating stuffs that serve technology applications of today.

Respiration Essay Example | Topics and Well Written Essays - 1000 words
Respiration - Essay Example Therefore, aerobic respiration only occurs when oxygen is present. The main food product that is utilized in this process is glucose. When glucose is oxidized, there is a production of energy, carbon dioxide, and water. The released energy is the form of Adenosine Tri-Phosphate (ATP). The process of aerobic respiration can be summarized using the equation C6H12O6 + 6O2 = 6CO2 + 6H2O + Energy (ATP) (Starr & McMillan 2012, p56). There are three main stages through which aerobic respiration takes place; Glycolysis, Krebs cycle, and the Electron Transport Chain. This process of aerobic respiration occurs in cytosol part of the cell. During this process, glucose is oxidized partially and broken down into pyruvate, which is a 3 carbon molecule. Glycolysis produces 2 ATP molecules and 2 NADH molecules. Each NADH molecule is responsible for carrying 2 energy electrons, which are later used by the cell (Starr & McMillan 2012, p56). This can be regarded as the second stage in aerobic respiration whereby the pyruvate molecule is processed to produce energy that is later stored between the bonds that hold the pyruvate molecule. The synthesized energy is released in the form of ATP (Starr & McMillan 2012, p.57). This is the last stage in aerobic respiration. This process is responsible for releasing the energy synthesized during glycolysis and krebs cycle. The electron transport chain comprises of a network of electron carrying protein located on the inner membrane of the mitochondria. It is in this stage where electrons and protons are added to oxygen to produce water. Production of ATP occurs when protons move across the cell membrane, a process referred to as chemiosis (Starr & McMillan 2012, p57). In times of strenuous exercises, there is consumption of high levels of energy, which implies that excess of ATP is needed. When there is insufficient oxygen the body respires

User Models and Models of Human Performance Essay
User Models and Models of Human Performance - Essay Example There are seven steps that are involved in developing a critical path model (Stanton 2007). The first is defining the tasks. In a situation where a driver is driving a car on the road and his mobile phone rings, the river will perform the following tasks: The second step identifies the input and output sensory modalities used in the tasks. For example, in retrieving the mobile, the driver will use his left or right hand, making the task step manual. Pressing buttons is also manual and can either be done by the right or the left thumb. Talking on the phone constitutes speech modality whereas listening requires auditory. Reading the screen requires visual modality and responding can involve cognitive modality. Step 3 of the approach requires construction of a chart, where dependency of the tasks is assessed (Sikora & Hattan 2009). The tasks need to be followed in a specific order, one after the other, and two tasks having the same modality need to be performed in series. Step 4 involves assigning the task time and these estimates should be accurate, unbiased and consistent (Thornley 2003). For example, retrieving the mobile can take five, six seconds on average, whereas talking can take long, depending on the duration of the conversati on. Pressing the buttons can take up to half a second each, whereas reading and looking at the screen can consume two to three seconds each. Then forward pass time needs to be calculated by adding up the individual times of each task, and, assuming a one minute long conversation, it becomes 73 seconds. Then backward pass is calculated. The last step is the calculation of the critical path, which is done by identifying the nodes which have zero difference between Earliest Start Time and Latest Finish Time. The model will provide a comprehensive procedure to make adjustments for variations in user performances. The arrangement of elements can be evaluated by a cognitive model and the design can be adjusted to outcomes of the

Your pick of this week's news week 11 (responses) Assignment
Your pick of this week's news week 11 (responses) - Assignment Example China, according to US intelligence, appears ready to launch a ââ¬Ëshort, sharpââ¬â¢ war with Japan,an allegation the Chinese vehemently deny. The US on its part vows to honor the defense treaties it has with Japan. While on the surface and in public the two nations appear to have a friendly relationship, what lies below all that seems more grotesque, and the two nations seem to be edging ever closer to a full scale conflict. The writer has also done a good job in showing the prelude to this conflict,which is one of mistrust between two of todayââ¬â¢s superpower nations. She has written about the events leading to this conflict. She has also, without bias, presented the cases that the two nations have in laying claim to the islands in question. In my opinion this is a top class news article, and the writer deserves a pat on the back. The article is titled "Rhode Island Settles Case on Jobs for the Disabled." It was written by Dan Barry and was published on April 8,2014 in The New York Time newspaper. The story looks at a landmark announcement by the department of Justice regarding employment for 3000-odd disabled people in Rhode Island. Prior to this agreement, it is estimated that ââ¬Å"450,000 people with intellectual and developmental disabilities while away their days in essentially cloistered environmentsâ⬠across the entire country. One of the disabled people interviewed expressed his discontentment with his job saying he ââ¬Å"did not like( the job) very muchâ⬠. The new agreement has lead to praise for Rhode Island for ââ¬Å"embracing the need for changeâ⬠. Under the new agreement, people with disabilities are allowed to ââ¬Å"obtain typical jobs within the community that pay at least the minimum wageâ⬠. In my opinion the article is true because one cannot doctor information about changes in the law. The writer also deserves commendation for highlighting such an important piece of legislation

CRM Essay Example | Topics and Well Written Essays - 1000 words
CRM - Essay Example 1. Introduction Is the customer always right? The customer may be the king, but is it worth pursuing to retain all the customer accounts? These are some of the dilemmas an organisation face, especially when a customer relationship have entered a cul-de-sac. The basic premise of customer relationship management is about attracting, developing, maintaining and retaining profitable customers over a period of time (Massey et al., 2001). Figure 1: The basic premise of customer relationship management Adapted from source: Massey et al., (2001) 2.Theoretical underpinning Payne and Frow (2005) delineate functional dimension of CRM and stated that it concerns with creating improved shareholder value through development of appropriate relationships with key customers and customer segments by making a fusion of the potential of relation marketing strategies with IT to create profitable, long-term relationships with customers and other key stakeholders. ... re 2: The service profit model suggested by Bentum and Stone (2005) Source: (Hussain et al., 2009, p.120) From the figure above, the service profit chain (SPC) is evident and urges that the value creation process is indeed a horizontal cross-functional process, rather than standalone views contained within each function (Heskett et al., 1994). Behind the theoretical underpinning of CRM, a major vector is to be able to fight competition; and an enterprise after implementing the CRM system should be profitable and add to shareholderââ¬â¢s value. However, at the core of the CRM remains the customer which must be attracted, developed, maintained, and retained in a profitable way. But does it mean that all the customers to be retained for as long as possible? Should the organisation pursue it with obsession? Saubertââ¬â¢s (2011) case study on ââ¬Å"Which accounts are worth keeping?â⬠provides a clue to this question. Saubert suggests that there should be a fruitful communion o f attrition propensity and profitability models (Saubert, 2011). Studying in the context of Australian Banks for credit card holders, Saubert opine that while devising customer retention strategies, firms should weigh the value earned from each customer. The firmââ¬â¢s CRM strategy needs to be guided by answer to two fundamental questions: Figure 3: Two fundamental question that must guide a firm's CRM strategy Adapted from source: (Saubert, 2011) Saubert (2011) opines that while firms usually strive to increase customer loyalty and reduce attrition but tend to overlook these two questions. The Performance Improvement Council (2008) states that in an ideal world, loyal long term customer relationships would eventually evolve towards partnerships and quotes Michael LeBoeuf, author of How to Win Customers & Keep
