The most appreciated single advancement which has brought significant change to the manufacturing industry is the digital computer. They are increasingly being employed in the design as well as in detailing of several components meant for engineering. Computer Aided Design (CAD) refers to the application of graphics and computer soft wares to advancement of product and systems design. CAD have enjoyed much appreciation in the industry because of several reasons including improved design quality, increased productivity, establishment of data base for manufacturing, creation of standards for design and doing away of inaccuracies brought about by hand-copying of several drafting as well as drawings’ inconsistency (Introduction to CAD, 2008). Computer Aided Manufacturing CAM (Computer Aided Manufacturing) refers to the effective employment of the computer technology for manufacturing planning and control. CAM is concerned with manufacturing engineering processes including planning and scheduling of manufacturing processes, machining operations, control of quality of production processes and products as well as Numerical Control (NC) part programming. Computer-aided manufacturing is usually integrated with Computer Aided Design in CAD/CAM systems. This allows movement of information from design section to product production planning with no need of entering the data manually on the part geometry(Introduction to CAD, 2008). CAM develops the information stored by CAD into information which is used as instructions for running and controlling production operations, machining, materials and equipment handling, product inspection and automatic testing. Rationale for CAD/CAM The rationale for CAD/CAM comes out to justify improvements based on technology as far as manufacturing is concerned. This approach grows as a result of the need to make improvements on quality, productivity and product competitiveness. Other major reasons include: Better quality of the produced goods, better communication, higher production level, manufacturing common database, lowered prototype costs of construction and quicker customers’ response(Introduction to CAD, 2008). CAD/CAM Hardware The necessary hardware part for a CAD/CAM system includes components such as a digital computer, workstation, plotters and output put devices as well as storage devices. The system, in addition to this encompasses an interface communication which usually enables data transmission to other systems of the computer. This enhances computer integration benefits(Katuhiko, 2009). The interface between the user in the CAD system and the computer system is the workstation. It is designed in a manner that it has, together with its features creates a significant manipulation to the productivity, convenience and the user’s output quality of work (Introduction to CAD, 2008). A digital computer that possesses high-speed central processing unit (CPU) must be included in the work station. The system also requires an efficient logic/arithmetic section. A hard disk is the commonly used secondary storage device in CAD/CAM system but sometimes a floppy diskette or both are employed(Katuhiko, 2009). In the CAD/CAM system, traditional input output devices are employed in transformation of data from a storage device or a human being to the computer system. This then allows the CAD functions to be carried out. An existing drawing can be inputted by use of two fundamental methods namely digitizing the drawing or modeling the particular object on a certain drawing. A CRT display is the standard output medium for the CAD/CAM system. The CRT display comes in two main forms namely the raster-scan displays and the random-scan drawing displays. Plasma panel displays and the liquid-crystal displays are also employed in cases where the CRT display is not used (Katuhiko, 2009). The CAD/CAM Software The work of software is to make the human user to convert a hardware configuration into a design and a manufacturing system which are significantly powerful. The software for CAD/CAM comes out in two main classes: 2-D and 3-D depending on the depending on the dimensions number. 2-D representations have been indicated the challenge of being well read and interpreted while 3-D have been viewed with much ease due to the 3-D planes which have height, width as well as depth which are easily visible. 3-D representation has commonly been employed in representation of images with graphics(Introduction to CAD, 2008). These representations have been representing the ideal shape as well as the form and appearance of the particular object which is being produced. This makes them to be easily read and understood. CAD/CAM Applications CAD/CAM has been widely employed in the manufacturing industry in several applications such as NC, Industrial robots and CNC machines. It has also found wide application in dies and molds design which are used in casting. This has enabled programming of shrinkage/allowances in the casting processes. Other CAD/CAM applications include quality control and inspection of produced goods, tools and fixture, EDM electrodes design and process planning and scheduling. CAD/CAM is also employed as a tool for visualization in generation if images which are shaded and displays of animations as well as in analysis of geometric models such as finite element analysis and kinematics analysis (Introduction to CAD, 2008). On materialization of the conceptual design in the mind of the designer, the geometric definition begins when there is relevant CAD system present. Selecting a geometric model to CAD becomes analogous as far as the mathematical model choice is concerned in the engineering analysis. This is inhibited where Finite Element Analysis needs the support of a different model apart from Kinematics analysis. The CAD system creates a valid geometrical model via its translator definition (Katuhiko, 2009). The CAD/CAM system implementation of typical CAD process looks like as shown below chart. AUTOCAD, on the other hand is system of computer-Aided Drafting and Design which has been implemented on personal computers. The system has been supporting a big number of devices and their drivers which include video display boards, plotters/printers and digitizers. AUTOCAD has been used to support drafting in 2-D as well as 3-D model wire frames. It is a single user package which produces lines, polylines with several widths, faces, circles and solids as its drawing elements. AUTOCAD as a drafting tool has interface which prompts the user in most of the applications(Introduction to CAD, 2008). Conclusion CAD/CAM has been widely used in the manufacturing industry in various applications. The use of CAD/CAM in the manufacturing industry has made significant impact to the industry. This has been experienced through standardization of development of products as well as lowering the effort of the task of designing, try out and prototype work. The system has improved productivity significantly hence reduced production costs. Reference Introduction to CAD. 2008. (Online). Available at: [login to view URL] [Accessed Jan 21, 2010].

Running Head: EVALUATION RESEARCH Evaluation Research Name: Course: University: Tutor: Date: 349123 Evaluation Research Graphic Displays Graphic displays like maps, diagrams and maps are used to provide models, support memory, attract attention, discovery and facilitate inference. They usually utilize space in conveying meaning in several approaches which are naturally cognitive. Icons, typically are employed in portraying elements with likenesses while depiction figures are for portraying other relations which are based on proximity. Darrell (1993) holds that statistics obtained from these graphical displays can be used to lie or be misleading. Poor use of statistics can be found any where; in polls, magazines, TV and even in some research papers. Maps, graphs or charts can be used to provide average (mean, mode and median) which is then employed in reporting results of a certain survey or experiment presented in the graphical displays. The mean, mode and median would be quite differing from each other depending on the data presented. Each will present a different result Sometimes graphical displays such as charts and graphs present ordinal data that does not require mean. Mean in this case becomes meaning less and would therefore present misleading information. Some graphs provide misleading information if they don’t provide the right scale which represents the actual variable. The use of magazines and newspapers sometimes give meaningless information with colorful pictures which are simple to represent survey responses and public opinion (Chudler, 2009). Therefore one has to be careful while reading these results. There is need to understand the nature of information being presented what most appropriate approach to present it. One has to be careful while making comparisons and as well use the independent variables to make comparisons. Descriptive statistics vs. inferential statistics Descriptive statistics are employed in quantitative terms to describe the most significant data collection features. They are distinguished from inferential statistics or inductive statistics in that they target to summarize quantitatively a set of data instead of supporting inferential statements regarding population which are represented by the data. Even when inferential statistical analysis is used to analyze data and draw conclusions more general presentations are done with more formal analysis by use of descriptive statistics to provide the audience with a sense of the analyzed data (Supercourse, 2009). Supercourse (2009) further asserts that examples of descriptive statistics include measure of central tendency, measure of association, measure of dispersion, histogram and cross-tab as well as contingency table. Performing a formal hypothesis test on some results is an example of inductive statistics. Parametric vs. Non parametric Parametric statistics are statistics having measurement of interval-level which the representative sample taken from a population that is considered normal. Non parametric statistics on the other hand are employed when dealing with ordinal or nominal measurement where assumptions require distribution normality. Evaluation Research By definition, evaluation refers to the systematic examination of an object’s merit or worth. Evaluation research is an area of research methodology which is closely related to traditional social research work (Trochim, 2006). This kind of research makes use of methodologies as traditional social research, however due to the fact that it happens in organizational or political environment, it demands management ability, skills of group work, political dexterity as well as multiple stakeholders sensitivity in addition to several other skills which social research does not rely on (Trochim, 2006). Types of Evaluation research The two major distinctions of evaluation research are formative and summative evaluation. i). Formative evaluation has various evaluation types including: Assessment of needs: this deals with several issues like the people needing the program, the greatness of the need as well as the strategies to use in order to achieve the need. Assessment of Evaluability: finds out if the evaluation has feasibility. Structured Conceptualization; assists stakeholders to elaborate the technology or program, expected results and the targeted population. Evaluation of implementation: examines the program fidelity ii). Summative evaluation includes: Evaluation of results, evaluation of effects, cost-effectiveness and cost-benefit analysis, secondary analysis and meta-analysis. Evaluation Questions and methods There are several questions and variety of approaches used to address these questions. a). Formative research questions and methodology i). What is the problem or issue definition and scope? ii). How big is the problem and where exactly is it? iii). In what ways can the program be delivered in order that it tackles the problem or issues. iv). What is the effectiveness of delivering the program? b). Summative research questions and methodology i). Is there any feasible evaluation? ii). Is the program effective and by how much? iii).What’s the program total effect? Some of the decisions to consider when choosing the most appropriate statistical data to employ in data analysis include: development of comprehensive database, financial marketing excel worksheet formatting of production data. This assist in using actual data and making of decisions. The statistician must consider the use of data when performing functions such as forecasting and prediction as well as statistical models. While applying the statistics to any problem solving, one needs to start with the process to be put under examination or rather the population. Design of Hypothesis study for criminal Justice Problem statement Criminal justice system is employed to maintain and uphold law in the society. These include preventing and controlling occurrence of crime. The system has been used for years to enforce laws, punish lawbreakers and try criminal cases. Despite this enforcement, several people have been breaking the law as opposed to the country’s laws. There is therefore the need to examine the reasons why these people break the law. Hypothesis Understanding the reasons why people break the law even after employing the law enforcement agencies and strong justice centers would assist in knowing the necessary strategies the justice system and the state should employ in preventing these crimes and if enforcing the law would make the criminals stop committing the crimes. The research design The kind of research would be evaluation research which would guide practice, law as well as the public policy. This evaluation would be employed to study if the policies, laws and policies have the required effectiveness. Quasi-experimental designs would thus be employed in the evaluation research. Statistics are contained in research concerning criminal justice and criminology (Trochim, 2006). Comprehending these statistics helps in handling the research in a more appropriate manner.
