Abstract:

Purpose The purpose of this paper is to present the design and evolution of the Dancing Computer project. Dancing Computer is an ongoing research project at the Michigan State University, which is developing a system that aims to increase computer literacy in elementary-aged children by teaching them first to read code before they write it. The main objective is to educate children on basic concepts of computer science. Design/methodology/approach Children are given tablet computers that present a simple program line-by-line that they execute as they pretend to be a computer. The programs are acted out on a portable dance floor consisting of colored tiles, and the program statements instruct the child to move, turn and act out dance poses and terminology. Findings The Dancing Computer prototype was tested in six different locations in 2016, reaching approximately 250 students. Learning was demonstrated by significant improvements in both task duration and error performance as students performed the activities. The most common errors were movement errors, where participants failed to move the correct number of squares. Social implications This project has the potential to increase the level of computer literacy for thousands of children. This project’s goal is to increase understanding of what a computer does, what a program does and the step-by-step nature of computer programs. Originality/value This is a unique and a different approach – the norm being to start students off writing code in some language. In Dancing Computer stages children as readers of programs, allowing them to pretend to be a computer in a fun and engaging activity while also learning how computers execute real programs.

Abstract:

Subjects analyzed data from typical ANOVA designs using three different computer programs. Several measures of cost, completion, and ease of program use were recorded and compared in a repeated measures Latin square design. Within time constraints and support that simulate an instructional setting, subjects could not answer the research questions using two traditional computer packages, but subjects completed all analyses using an interactive personal computer program designed to minimize computer-related difficulties. Such results can be useful in guiding design of instructional strategies and computer programs.

Abstract:

It is urgently necessary to develop practical programs for different purposes in the field of wastewater treatment. Now the design programs for grit chambers, anaerobic ponds, facultative ponds, aerobic ponds, aerated ponds and polishing ponds are being developed. Programs for automated plotting and man-machine interactive plotting are needed too. By using AutoCAD (Version 9.03 or 10.0), a secondary development of the softwares for engineering drawing of stabilization pond has been developed, which possesses the function of writing out explanatory notes. A program for writing out explanatory notes in Chinese is also being developed. In the process of developing such softwares, high-level language AutoLISP is used, so that the softwares possess artificial intelligence. Up to now the graphic softwares for plotting the general plan drawings and elevation drawings of grit chamber, various ponds, and pond systems have been developed.

Abstract:

This paper proposes a simplified design of a press body manually using a model consisting of a double symmetrical frame flush. Both Mathcad and Solidworks programs were used to determine the dimensions and drawings. MathCad is a very complex program, but also very useful for engineers, researchers, mathematicians, students, teachers, and all those who use math. Mathcad is a much better way to perform and manage engineering calculations, making them easy to achieve, understand, verify, communicate, and logically follow. SolidWorks is a solid modeling computer-aided design (CAD) and computer-aided engineering (CAE) computer program that runs on Microsoft Windows.

Abstract:

Objective: A computer program for social work practice research was created and then tested. This program was designed specifically for computer tasks of data entry, data analysis, and graphic presentations of single-system-design research in social work practice. Method: An evaluation of this program was conducted with 136 students at one master's of social work (MSW) program in the spring of 1996. Results: More than 95% of the students surveyed found the program added a valuable component to research, and 81.9% reported the program helpful in evaluating practice. Conclusions: Computer software programs that are research design specific may encourage more social workers to do practice evaluation studies, but further development and testing of these types of specialized programs is called for.

Abstract:

As part of a larger study developing dietary software, this study aims to evaluate a sample of potential users for their experience and comfort with computers, and assess the preferred program design and navigation features for the development of the automated diet history interview. A telephone-based questionnaire and focus groups were employed to evaluate the perceptions, beliefs and attitudes of 37 older adults with type 2 diabetes mellitus. Participants were also shown a range of existing dietary assessment programs and asked to state their perceptions of each. Data was coded and thematically analysed based on computer use, software features, dietary assessment and nutrition programs using N-Vivo software. Three participants had never used a computer, yet others had used computers, and were comfortable using them. For navigation about the program, a preference toward text was identified whilst photographs were preferred for determining food portion sizes. Reduction in the complexity of screen layouts was important and the time to be spent using the program varied widely with a minimum of 10 minutes reported. Development of the computerised dietary assessment program must ensure simplicity of the interface design and flexibility of the locations of use for the older computer user.

Abstract:

The objective of this symposium is to provide different perspectives on how screen design in computer systems can be improved. Screen design refers to the layout and format of all computer screen information. This includes tutorials, help panels, prompts, and messages. Since screen design affects how easily information can be retrieved or stored, it determines how effectively the computer system can be used. Finding ways to improve screen design should be an important goal in the development of virtually all interactive programs. Achieving good screen design is becoming even more important as programs are used by more people, particularly those not familiar with computers, and as more information is presented online. The presenters for this symposium provide a wide range of views, experiences, and approaches for improving screen design. As a result, they each contribute unique methods and suggestions. Annette Bradford provides guidelines and views of screen design based on her work as an information developer. Joe Dumas provides views of screen design based on his work as an interface analyst. David A. Schell provides views on usability testing of screen design. Thomas Tullis provides an alternative way of testing screen design with his research-based computer program.

Abstract:

The purpose of the research is to develop formulas, expressions and a computer program for concrete airfield pavement design under the impact of all Airbus 380 main landing gears taking into consideration the design factor of tensile stresses at the top and bottom of a concrete slab. The top-down cracking in concrete slabs has not been directly simulated in structural analysis models used for one- and two-layer concrete airfield pavement design by the Ukrainian Standard. Empirical formulas for the calculation of top tensile stress and the coverages to failure using the criterion of top tensile stress are obtained. Computer program “Aerodrom 380” has been developed for the design of concrete airfield pavement thickness. It provides the required thickness of a concrete slab needed to support an Airbus 380 over a particular subgrade and uses the bottom and top tensile stresses as design factors. “Aerodrom 380” contains a fatigue function for determining the number of coverages to failure permissible for a concrete slab before it has top-bottom and bottom-up cracks. The results obtained with this program are compared to other solutions using the Ukrainian Standard SNiP 2.05.08–85, “LIRA-SAPR”, software and the FAARFIELD computer program. The anticipated life of a concrete airfield pavement calculated using computer program “Aerodrom 380” is about 70% of the FAARFIELD pavement life.

Abstract:

This article discusses that computer-based technologies have greatly influenced the way design engineers work. The first technological innovation was the use of high-powered personal computers. With PCs, engineers had access to high-speed applications of computer-aided design software right at their own desks. Personal computers took the place of rulers and pencils. The second innovation, he said, is the advancing capability of PCs to function as supercomputers, crunching numbers much faster than formerly possible. By taking advantage of this technology, engineers untrained in a mathematical application such as finite element analysis can run an FEA software program that performs calculations automatically and will shave weeks off the design process. Hothouse uses the Spatial technology to repair CAD models brought in from outside sources and to translate CAD files the company sends to its suppliers, collaborators, and clients. Before Hothouse began sending CAD files to the online service, company employees spent days repairing or rebuilding files on their own. Sometimes suppliers or clients that received Hothouse CAD files had to do similar work on their end.

Abstract:

Recent progress in computer technology enables the calculation of lens fields and focal properties on commonly available computers such as IBM ATs. If we add to this the use of graphics, we greatly increase the applicability of design programs for electron lenses. Most programs for field computation are based on the finite element method (FEM). They are written in Fortran 77, so that they are easily transferred from PCs to larger machines.The design process has recently been made significantly more user friendly by adding input programs written in Turbo Pascal, which allows a flexible implementation of computer graphics. The input programs have not only menu driven input and modification of numerical data, but also graphics editing of the data. The input programs create files which are subsequently read by the Fortran programs. From the main menu of our magnetic lens design program, further options are chosen by using function keys or numbers. Some options (lens initialization and setting, fine mesh, current densities, etc.) open other menus where computation parameters can be set or numerical data can be entered with the help of a simple line editor. The "draw lens" option enables graphical editing of the mesh - see fig. I. The geometry of the electron lens is specified in terms of coordinates and indices of a coarse quadrilateral mesh. In this mesh, the fine mesh with smoothly changing step size is calculated by an automeshing procedure. The options shown in fig. 1 allow modification of the number of coarse mesh lines, change of coordinates of mesh points or lines, and specification of lens parts. Interactive and graphical modification of the fine mesh can be called from the fine mesh menu. Finally, the lens computation can be called. Our FEM program allows up to 8000 mesh points on an AT computer. Another menu allows the display of computed results stored in output files and graphical display of axial flux density, flux density in magnetic parts, and the flux lines in magnetic lenses - see fig. 2. A series of several lens excitations with user specified or default magnetization curves can be calculated and displayed in one session.

Abstract:

The computerization of pipeline design is relatively important for the engineering feasibility of submarine pipelines. The changing environmental conditions make difficulties for the stability calculation of each pipe segment on line. For this reason, the computer study will provide many advantages during the design of pipeline. The different environmental and functional parameters can be easily tried on line and the most suitable size of structure against the extreme environmental conditions can be determined. This study deals with the general design principles especially including the engineering studies, i.e. wave statistical analysis, transformation of waves, stability analysis, and developed computer program to achieve both the stabilization of pipeline and aid for drawing the route together with user in some stages of the design. Finally, the outline of the program is briefly described and a flow chart is presented.

Abstract:

RedesignIT is a computer program that uses model-based reasoning to generate and evaluate proposals of redesign plans for engineered devices. These proposals describe how the design parameters could be changed to achieve a specified performance goal. Equally important, the program proposes complementary modifications that may be necessary to counteract the undesirable side effects of the primary changes. RedesignIT is intended for use during the first stages of a redesign project, when engineers need to make a quick, yet accurate assessment of the overall effects of a particular design change. The program uses qualitative device models, which allow it to compute redesign plans efficiently. With its ability to predict the collateral, and probably undesirable, effects of a design change, the program is well suited to aid product designers in deciding on the feasibility of introducing design changes to a product.

Abstract:

This article highlights about the fact that many speculate on the outcomes of design, but how many consider the process by which designs are executed. The seed for many of these emerging interdisciplinary programs in design is not new either—cutting-edge research and advancements invariably lie at the boundaries of departmental silos. The product-architecture program at Stevens has successfully integrated architecture, engineering, computation, and product development, attracting students with wide-ranging interests and diverse backgrounds in architecture, visual arts, industrial design, mathematics, computer science, and mechanical, aerospace, and biomedical engineering. By focusing on the product or system being designed, the program is dissolving boundaries in design education and launching students along trajectories of design leadership and social entrepreneurialism. As globalization moves engineering, business, and design closer together, many argued that interdisciplinary graduate design programs are the future for the United States to maintain its position in product leadership.

Abstract:

Computer programs that combine traditional numeric methods with symbolic algebra and with specific knowledge of application-based techniques can provide new levels of computational support for engineering design. We illustrate this with a computer-based ‘control engineer’s assistant’. Although this program is focussed on control system design, it demonstrates techniques that should be widely applicable across many engineering disciplines. In particular, we show how, with symbolic computing, a computer-aided design system can usefully simulate engineering models early in the design process, before all (or any) system parameters have been specified numerically. Our system employs a flexible, extensible, object-oriented representation for control systems, which admits multiple mathematical models of designs and provides a framework for integrating tools that operate on diverse representations.

Abstract:

The underlying theoretical assumptions, goals, design, and implementation of a Computer-Aided Speechreading Training system (CAST) are described as a case study in program design. This computerized speechreading assessment and training system simulates face-to-face intervention and is designed to be one component of a comprehensive aural rehabilitation program for preretirement adults with acquired mild-to-moderate hearing loss. The interactive, automated course consists of eight training lessons, each focusing on a particular viseme that is practiced by a modified discourse tracking method using viseme-specific texts. Three basic speechreading skills are emphasized: visual speech perception, use of linguistic redundancy, and use of feedback between message sender and receiver. These skills are evaluated separately by means of CAST tracking rate, receiver strategy, and inferred error type. Four example case assessments are provided to illustrate the potential applications of CAST as a standardizable rehabilitative tool. An independent program evaluation is provided in a companion paper (Gagné, Dinon, & Parsons, 1991). Comparisons between CAST, face-to-face tracking procedures, and natural discourse are presented and discussed with reference to theoretical and clinical issues in speechreading and program evaluation.

The design module performs an automatic optimum design of anchor deployment for any environmental condition, or allows the user to perform an interactive design. The static simulator predicts system responses in all mooring operations. The dynamic simulator is an implementation of the recent requirement of regulatory bodies for simulating slow-drifting motions of the vessel after a line failure. The calculator includes modules that compute weather forces, system stiffness, elastic catenary mechanics, and others. The program is interactive, menu-driven, and includes graphics.

Abstract:

This paper describes the structure and operation of a low-cost computer aided design system for press tool design (CAPTD). The system is a collection of integrated industry standard microcomputer packages and purpose-built programs. The packages include AutoCad 11, for the input of workpiece geometry and the output of the press tool part and assembly drawings, and dBase IV for the decision support, the selection of press tool components and generating output reports. A purpose built ‘C’ program is also developed for the layout and nesting of the workpiece. The system is driven by a set of press tool design rules implemented in both the dBase IV and ‘C’ programming languages. The system is developed to run on 80386SX or higher based IBM-compatible microcomputers.

Abstract:

Analysis and design of structures located offshore involves the simulation of the ocean wave process in order to select a design load. This is a rigorous process that involves the solution of difficult mathematical equations. This study presents an efficient computer program for the simulation of the wave. The program was designed in such a way that only the wave parameters for a given location are required as input. The program then simulate the wave using Karhunen-Loeve series representation in which the eigenfunctions of Prolate Spheroidal Wave Functions are developed and used. The use of the program was demonstrated by simulating an example wave.

Abstract:

A case study of Critical Path Management (CPM) and the application of this concept to the management of ship design programs are presented. The evolution of modular ship construction and its attendant influence on design products have created a need for an integrated management approach. CPM is presented as the preferred method of managing the effective integration of ship design with ship construction. Although CPM was established in the 1940's, it was not a practical alternative for managing complex, large-scale projects until mainframe computers became widely available to American business. The CPM process is essentially one of developing a computer model of the management plan required to meet the primary goals of the ship design program. By modeling a management plan that includes the key elements of both design development and ship construction in an integrated computer environment, accurate schedules and resource requirements are produced. More importantly, if the performance to these schedules deviates, either positively or negatively, the net impact to the program is immediately known.

Abstract:

Generation of the part programs, or tool paths, for products to be manufactured by computer numerical control (CNC) machines is very important. Many methods have been used to produce part programs, ranging from manual calculations to computer aided design/ manufacturing (CAD/CAM) systems. This work introduces a new technique for generating the part programs of existing products using the latest technology of computer vision. The proposed vision system is applicable for two-dimensional vertical milling CNC machines and is calibrated to produce both metric and imperial dimensions. Two steps are used to generate the part program. In the first step, the vision system is used to capture an image for the product to be manufactured. In the second step, the image is processed and analysed by software specially written for this purpose. The software CNCVision is fully written (in lab) using Microsoft Visual C++ 6.0. It is ready to run on any Windows environment. The CNCVision software processes the captured images and applies computer vision techniques to extract the product dimensions, then generates a suitable part program. All required information for the part program is calculated automatically, such as G-codes, X and Y coordinates of start-points and end-points, radii of arcs and circles and direction of arcs (clockwise or counterclockwise). The generated part program can be displayed on screen, saved to a file or sent to MS Word or MS Excel. In addition, the engineering drawing of the product can be displayed on screen or sent to AutoCAD as a drawing file.

Abstract:

Geneva mechanism is used as a mechanism for transforming rotary motion into intermittent motion and is able to achieve a precise movement and its lock, which makes it usable in many areas, particularly in timer devices, measurement devices, feed mechanisms, positioning mechanisms, pick-up and transport machinery, textile machinery etc. The studied literature showed that, although it has long been known, this mechanism is still interesting for contemporary researchers. The present paper proposes a method of synthesis and a computer-aided kinematic and dynamic analysis for this mechanism. Based on input data, it was developed a computer program that computes the dimensions of components of Geneva mechanism and determines velocity acceleration and displacement of Geneva wheel. The dimensional calculated data were also used to obtain 3D model of the mechanism.

Abstract:

The valve design of a rear twin tube shock absorber belongs to a light commercial vehicle whose damper characteristics already known has been realized by the help of a computer program called “Dr”, and compared with the actual application results. The program gives user results about the valve parts to get the right target characteristics. After obtaining the necessary parts’ results, the needed damping performance test has been performed by the shock absorber, which has been conflated according to the program. The actual results and target characteristics were compared. ”Dr” program enables the user to select the correct parts to be used in valve system by detecting every effect on target characteristics diagram. By comparing the overall effect of the parts selected, shock absorber valve system is conflated according to the valve components obtained from the computer program.

Abstract:

This paper focuses on an important trend that is increasing shipbuilding productivity: integrating the computer-aided ship design process. The ship design process increasingly is being performed with the help of computer programs, either individual programs that address single aspects of the design or integrated programs composed of modules that address a range of ship design aspects. In the case of integrated computer programs, the ship design process is enhanced through individual program modules sharing their results with each other, preferably from a common database. Modern integrated ship design programs not only improve the efficiency of ship design, they also improve the efficiency and ease of ship production, from lofting and numerical cutting to providing workshop drawings and production information.

Abstract:

The counterforce wall and pedestral is a complex system. Computer aided design technology is used to design and analyze this reinforced and prestressed concrete structure. Firstly CAD design program is used to design a representative wall section as a separate component. It helps doing ultimate limit state calculation and serviceability limit state checking computation. The prestress on concrete induced by prestressing steel according to construction method is also computed. Secondly, a finite element program is used to analyze the whole system. The prestress computed by CAD design program is regarded as external load. Simulation technology is also described in this paper. The stress, strain and deformation of the whole prestressed system are calculated and checked. Moreover, dynamic structural analysis is done by finite element program. Then vibration frequencies and modes can be obtained. By combining CAD design with finite element program, this complex system can be designed reasonably and effectively.

Abstract:

Abstract In general, one cannot use algebraic or enumerative methods to optimize a quality-control (QC) procedure for detecting the total allowable analytical error with a stated probability with the minimum probability for false rejection. Genetic algorithms (GAs) offer an alternative, as they do not require knowledge of the objective function to be optimized and can search through large parameter spaces quickly. To explore the application of GAs in statistical QC, I developed two interactive computer programs based on the deterministic crowding genetic algorithm. Given an analytical process, the program "Optimize" optimizes a user-defined QC procedure, whereas the program "Design" designs a novel optimized QC procedure. The programs search through the parameter space and find the optimal or near-optimal solution. The possible solutions of the optimization problem are evaluated with computer simulation.

Abstract:

The problem of absorbing CAD system defined objects into detector simulation programs like GEANT is a well known unsolved problem in HEP computing. The nature of the problem and potential approaches to a solution are discussed. A solution to one aspect of CAD to GEANT translation is presented where CAD defined objects are represented as a tree of boxes which is then absorbed into GEANT geometries. Space and time benchmarks are discussed.
