Abstract:
Introduction:It is known that the computer users develop the features of dry eye. Objective: To study the cytological changes in the conjunctiva using conjunctival impression cytology in computer users and a control group. Materials and methods: Fifteen eyes of computer users who had used computers for more than one year and ten eyes of an age-and-sex matched control group (those who had not used computers) were studied by conjunctival impression cytology. Results: Conjunctival impression cytology (CIC) results in the control group were of stage 0 and stage I while the computer user group showed CIC results between stages II to stage IV. Among the computer users, the majority ( > 90 %) showed stage III and stage IV changes. Conclusion: We found that those who used computers daily for long hours developed more CIC changes than those who worked at the computer for a shorter daily duration.

Abstract:
Twenty years ago Abelson and Sussman's Structure and Interpretation of Computer Programs radically changed the intellectual landscape of introductory computing courses. Instead of teaching some currently fashionable programming language, it employed Scheme and functional programming to teach important ideas. Introductory courses based on the book showed up around the world and made Scheme and functional programming popular. Unfortunately, these courses quickly disappeared again due to shortcomings of the book and the whimsies of Scheme. Worse, the experiment left people with a bad impression of Scheme and functional programming in general. In this pearl, we propose an alternative role for functional programming in the first-year curriculum. Specifically, we present a framework for discussing the first-year curriculum and, based on it, the design rationale for our book and course, dubbed How to Design Programs. The approach emphasizes the systematic design of programs. Experience shows that it works extremely well as a preparation for a course on object-oriented programming.

Abstract:
This paper presents a study developing a model of the ontology of an apparel product and the design thereof. Here, “ontology” means the concepts and relationships between them for apparel and apparel design; ontology models are also called conceptual models. To the best of our knowledge, such a model has not yet been made in the literature of apparel and apparel design. A conceptual model is a foundation for (1) effective human-human communication and collaboration, (2) facilitating the communication among different computer programs for computer-aided design (CAD) of apparel products, and (3) facilitating human-computer interactions necessary to design an apparel product. The conceptual model developed completely captures the semantics of apparel and design, including the 2D pattern and 3D apparel product. An example is presented, providing an impression of the usefulness of this model.

Abstract:
Foot orthotic treatment is one of the major conservative methods used to handle foot problems. Total plantar contact foot orthoses are used to reduce and redistribute peak pressures. For the fabrication of a total plantar contact foot orthosis, the computer-aided design and computer-aided manufacturing (CAD-CAM) method has been applied. In this study, the plantar foot-orthosis interface pressure data during walking were collected by the Novel Pedar-mobile in-shoe plantar pressure measuring system. The data were collected under three conditions: (i) Flat insole, (ii) foot orthosis provided by the CAD-CAM method, and (iii) foot orthosis provided by the foam impression method. The Swiss Comfort CAD-CAM foot orthotics system was used in this study. For conditions (ii) and (iii), foot shapes were collected in partial weight bearing and subtalar neutral conditions. Thirty normal subjects were recruited for this study. The plantar foot surface was divided into eight plantar foot regions and then was investigated. These regions included the heel, the medial and lateral arches, the medial, mid and lateral forefoot, the hallux, and the lateral toes. The results showed that the orthoses provided by both the CAD-CAM and foam impression methods could decrease the peak pressure and the maximum force in the heel region, and increase the peak pressure and the maximum force in the medial arch region. Both orthoses redistributed the peak pressure and the maximum force from the heel to the medial arch region. The peak pressure in the mid forefoot region was different between the orthoses provided by the CAD-CAM and foam impression methods.

Abstract:
With the advance of time, our inventory of simulation programs has and continues to accumulate. To maximize the return on our investment of time and money into these software systems, it is advantageous for us to reuse software components as much as possible. For example, previously engineered simulation models can often be reused and exercised under a new set of experimental conditions. Before a software component can be reused, the analyst must learn and understand its functionality. This learning process is often made unnecessarily difficult due to incomplete documentation. Another contributing factor is the complexity brought about by interacting directly with the program code. Furthermore, when it comes time to make updates to the code, the potential arises for semantic and syntactic errors to work their way into the program. Knowledge-based program understanding systems with built in quality assurance can be used as an environment for simplifying the learning and the update processes, while ensuring an acceptable degree of quality has been maintained during the update process. This thesis discusses program understanding and quality assurance issues related to the Slam II programming language and discusses the architecture of E/Slam (Elucidation of Slam II programs). E/Slam is a knowledge-based program understanding system with built-in quality assurance ability.

Abstract:
The purpose of this creative project was to develop a promotional videotape to be used in the marketing process of Micro Coin(TM). This area had not been explored before by Micro Coin Electronics Incorporated. Based on the information given to me about Micro Coin I was given total control of the content of the videotape. I based my creative project on comparing current marketing techniques of computers and computer software, and Micro Coin builds and improves those techniques. Micro Coin is such a revolutionary idea, there was the need to show an example of Micro Coin being used. I learned that even with total control creativity is limited.

Abstract:
Les travaux présentés dans cette thèse sont lies aux problèmes de vérification de l'atteignabilité et de la terminaison de programmes qui manipulent des données entières non-bornées. On décrit une nouvelle méthode de vérification basée sur une technique d'accélération de boucle, qui calcule, de manière exacte, la clôture transitive d'une relation arithmétique. D'abord, on introduit un algorithme d'accélération de boucle qui peut calculer, en quelques secondes, des clôtures transitives pour des relations de l'ordre d'une centaine de variables. Ensuite, on présente une méthode d'analyse de l'atteignabilité, qui manipule des relations entre les variables entières d'un programme, et applique l'accélération pour le calcul des relations entrée-sortie des procédures, de façon modulaire. Une approche alternative pour l'analyse de l'atteignabilité, présentée également dans cette thèse, intègre l'accélération avec l'abstraction par prédicats, afin de traiter le problème de divergence de cette dernière. Ces deux méthodes ont été évaluées de manière pratique, sur un nombre important d'exemples, qui étaient, jusqu'a présent, hors de la portée des outils d'analyse existants. Dernièrement, on a étudié le problème de la terminaison pour certaines classes de boucles de programme, et on a montré la décidabilité pour les relations étudiées. Pour ces classes de relations arithmétiques, on présente un algorithme qui s'exécute en temps au plus polynomial, et qui calcule l'ensemble d'états qui peuvent générer une exécution infinie. Ensuite on a intégré cet algorithme dans une méthode d'analyse de la terminaison pour des programmes qui manipulent des données entières.

Abstract:
AbstractWe revisit two well-established verification techniques, k-induction and bounded model checking (BMC), in the more general setting of fixed point theory over complete lattices. Our main theoretical contribution is latticed k-induction, which (i) generalizes classical k-induction for verifying transition systems, (ii) generalizes Park induction for bounding fixed points of monotonic maps on complete lattices, and (iii) extends from naturals k to transfinite ordinals $$\kappa $$ κ , thus yielding $$\kappa $$ κ -induction.The lattice-theoretic understanding of k-induction and BMC enables us to apply both techniques to the fully automatic verification of infinite-state probabilistic programs. Our prototypical implementation manages to automatically verify non-trivial specifications for probabilistic programs taken from the literature that—using existing techniques—cannot be verified without synthesizing a stronger inductive invariant first.

Abstract:
Chapter 3 tells the story of the visionaries that first imagined the computer. In the 19th century, Charles Babbage invented a mechanical computer but failed in his attempts to build it. He and Ada Lovelace wrote a series of programs for the proposed machine. These programs were the first transcriptions of algorithms into sequences of machine executable instructions. After Babbage’s failure, the idea of building a real computer was abandoned for fifty years. As a young PhD student, Alan Turing forever defined the relationship between algorithms and computers. According to his definition, a computer is a machine that performs algorithms. He devised a theoretical computer that allowed him to investigate the limits of computation. This, before a single computer was ever built. Turing went on to work as a cryptographer during World War II. Turing outlined the future of computing but tragically died at the age of 41.

Abstract:
Meritocracy flourished most luxuriantly in Harvard’s professional schools. The Big Four—the Graduate School of Arts and Sciences and the Schools of Law, Medicine, and Business—threw off the constraints of lack of money and student cutbacks imposed by World War II. The smaller professional schools—Public Health and Dentistry, Education, Divinity, Design—shared in the good times, though their old problems of scarce resources and conflicted missions continued to bedevil them. The major alteration in the Harvard postgraduate scene was the establishment of the Kennedy School of Government. By the time Derek Bok—as well disposed to the Kennedy School as Conant was to Education and Pusey to Divinity—became president in 1971, this new boy on the Harvard professional school block was well situated to capitalize on his good favor. The Graduate School of Arts and Sciences remained, as in the past, rich in renown, poor in fund-raising and administrative autonomy. Between 1952 and 1962, fewer than 5 percent of GSAS alumni donated a total of about $60,000; during the early sixties giving went down to $3,000 a year. Its dean had little or no budgetary or curricular control; its faculty, curriculum, and student admissions were in the hands of the departments. In 1954 Overseer/Judge Charles Wyzanski grandly proposed that admissions to the Graduate School be sharply cut back. The reduction, he thought, would free up the faculty for more creative thought, improve undergraduate education, and upgrade the level of the graduate student body. But the post–Korean War expansion of American higher education led to boom years for the Graduate School. In 1961, 190 male and 60 female Woodrow Wilson Foundation Fellows, more than a quarter of the national total, chose to go to Harvard or Radcliffe; 80 of 172 National Science Foundation grantees wanted to go to Harvard. A 1969 rating of the nation’s graduate programs gave Harvard Chemistry a perfect 5, Mathematics 4.9, Physics, Biochemistry, Molecular Biology, History, and Classics 4.8, Art History and Sociology 4.7, English and Spanish 4.6, Philosophy and Government 4.5. Impressive enough, all in all, to sustain the faculty’s elevated impression of itself. But in the late sixties the Graduate School bubble deflated. Government aid, foundation fellowships, and college jobs declined; student disaffection grew.

Abstract:
An information management and mapping system combining a series of interactive computer programs for stratigraphic, lithofacies, paleogeographic, and structural analysis interfaced with a comprehensive database on subsurface geology produces contour maps of quantitative variables including structure maps, isopach maps, and maps of lithofacies parameters; detailed lithologic and stratigraphic logs; and printouts of lithofacies parameters for all levels of the lithostratigraphic subdivision. Users communicate by means of simple, on-screen, menu-driven dialogues controlled by FORTRAN programs. The system runs on DEC/Micro VAX II computers operating under VMS. This information management and mapping system for subsurface stratigraphic analysis is an integration of a comprehensive database on the subsurface geology of Israel and a series of computer programs for stratigraphic, lithofacies, paleogeographic, and structural analysis. Development of the system, referred to as "ATLAS -RELIANT," was sponsored by OEIL [Israel Oil Exploration (Investment) Ltd.). The system serves primarily as a storage and retrieval facility for information on the subsurface geology of Israel. Users can obtain printouts of lithologic and stratigraphic logs, contour maps, and value maps. The system originally was developed to run on a CDC machine under the NOS/BE operating system. Later OEIL expanded the database to include many additional items of information [inventory of cores and petrophysical logs, results of production tests, results of petrophysical analyses, geochemical analyses of recovered fluids (water samples and hydrocarbons), and results of quantitative analyses of petrophysical logs] and the system was modified to run on DEC/Micro VAX II computers under the VMS operating system (Shertok, 1969). Among other things, the ATLAS-RELIANT system was instrumental in the regional stratigraphic analysis of the subsurface geology of Israel performed by OEIL during 1968-1988 (OEIL, 1966; Cohen et al., 1990). The database, dubbed "ATLAS," is about 16 MB in size and contains information on 320 petroleum exploration and development boreholes, 50 deep water wells, and 100 columnar sections of outcrops.

Abstract:
Additive manufacturing, fundamentally, is computerized numerical controls using a specialized printer head as the “tool”. Any new curriculum implementing “additive manufacturing” stands upon the fundamental and advanced work done before in computer numerical controls. Although there certainly is a need for end user laboratories based upon purchased printers, the challenge in designing curriculums that support developing the next generation of additive manufacturing must also include computer numerical controls. The best designers must be able to picture the entire system when developing new systems. During the late twentieth and early twenty-first centuries, the “hands-on” engineering laboratories typical of the post-World War II engineering campus gave way to computerized laboratories and simulation. Traditional engineering assets (lathes, mills, drill presses, etc.) were retired as they aged without replacement in favor of computer laboratories full of PC’s and software. As the 20th century ended, there was a realization that computer simulation is no substitute for “cutting metal” or “making things”. Designers need to understand process in order to communicate with technologists from trade schools and industry. Even a simple engineering drawing can often simply not be created due to process limitations (e.g., a perfectly drawn internal 90-degree angle in a CAD drawing does not occur in nature OR a machine shop). As the four year universities shut down their hands on programs, the two year programs implemented complex computer numerical controls curriculums to train operators for industry. The incredibly expensive equipment needed to do this is funded by state governments trying to attract industry to the state. The four year universities, responsible for creating the next generation of manufacturing machines, do not have access to THIS generations machines. The National Science Foundation and state governments don’t see the need for upper level engineering students to have ready access to machines that cost up to a million dollars each. The universities fortunate to have CNC machines usually keep them locked away from the students for safety of the machines and the students. Technicians make things for the students on the limited number or machines available. There is no understanding of the machines and very little understanding of the processes the machines are doing. An earlier paper by the authors described a way to implement an affordable undergraduate “manual” innovation laboratory. This article describes an affordable way for upper level universities to implement an effective machine design atmosphere for subtractive and additive manufacturing. The students modify existing machines from that earlier laboratory into multi-axis CNC machines. Students have successfully built five axis mills, lathes with live tooling and now a unique metal printing machine. The goal is not to create operators, but to enable designers of the next generation of machines. At the very least, students are immediately useful as design engineers when hired by companies making the most advanced (and expensive) additive/subtractive machines. The emphasis is not on expensive super machines but on very capable simple machines as emphasized in the Toyota Production System. One specific, inexpensive example will be provided for other institutions to utilize. The result has been an affordable laboratory that supports undergraduate students, graduate research students, and the university as a whole while teaching the design and control of computer numerical machines.

Abstract:
Abstract The contents of the paper cover the determination of conditions : (i) of nonundercutting by axial and axial-radial generation of internal gears by shapers, and (ii) avoidance of interference by axial and axial-radial assembly. The authors have developed computer programs for simulation of undercutting and interference, design charts and a table that allow to determine the limiting number of teeth of the cutter and pinion considering the tooth number of internal gear as known. The details of developed algorithms are given in Appendices. The paper is illustrated with computer graphics and numerical examples.

Abstract:
This paper presents the implementation of a numerical algorithm for the direct solution of optimal control and parameter identification problems. The problems may include differential equations that define the state, inequality constraints, and equality constraints at the initial and final times. The numerical method is based on transforming the infinite dimensional optimal control problem into a finite dimensional nonlinear programming problem. The transformation technique involves dividing the time interval of interest into a mesh that need not be uniform. In each subinterval of the mesh the control input is approximated using a piecewise polynomial. In particular, the control can be approximated using: (i) piecewise constant, (ii) piecewise linear, or (iii) piecewise cubic polynomials. The explicit Runge-Kutta method is used to obtain an approximate solution of the differential equations that define the state. With the approach used here the states do not appear in the nonlinear programming (NLP) problem. As a result the NLP problem is very compact relative to other numerical methods used to solve nonlinear optimal control problems. The NLP problem is solved using a sequential quadratic programming (SQP) technique. The SQP method is based on minimizing the L1 exact penalty function. Each major step of the SQP method solves a strictly convex quadratic programming problem. The paper also describes a simplified interface to the computer programs that implement the method. An example is presented to demonstrate the algorithm.

Abstract:
The Babcock & Wilcox Company (B&W) has developed a rule-driven design (RDD) computer application to speed the design of its wet flue gas desulfurization (WFGD) slurry spray header system including support steel. The application, written using the RuleStream RDD system, captures the talents of the many people involved in the spray system’s design, including those involved in process engineering, design engineering technology, structural mechanics, and technical design. B&W’s design standards and best practices are blended with fabricator capabilities and industry standards to form the application rules. Third-party software (for example CAESAR II) and proprietary computer programs are leveraged by the application courtesy of the RuleStream RDD architecture. The application seeks to automate the routine first 80% of the design, while providing interfaces to complete the design or explore “what-if” situations. Interfaces allow the evaluation of spray coverage, pipe velocities, pressure drop, physical clearances, weights, and stresses. The application generates drawings, a solid model, and a bill of material for fabrication. Using the application, repeatable, consistent results are achieved. There is a higher confidence in the generated design and a reduction in design cycle time. This saved time may be allocated to exploring alternative designs, pursuing fabricator quotes, performing contract level analysis in the proposal phase, or may be applied to other areas of the WFGD design.

Abstract:
Abstract A multi-phased evaluation of the Iowa Driving Simulator as a virtual proving ground for construction equipment simulation is presented. In Phase I the Iowa Driving Simulator was evaluated in an “open-loop” mode to assess its capability to simulate a typical maneuver common to wheel loader operation, and its viability as a test platform for human subject evaluation of those maneuvers. A typical wheel loader truck loading cycle involves numerous directional shifts. Cycle productivity is increased if these shifts are executed at full engine throttle. Jerk and acceleration levels associated with full throttle shifts, however, can cause both operator discomfort and spillage of loaded material. Electronically controlled transmissions have the potential to both minimize directional shift times and material loss while optimizing operator comfort. This optimization will require an understanding of the factors which affect operator comfort during shifts. A study was therefore devised to determine those aspects of the motion generated by a directional shift which affect operator comfort. The Iowa Driving Simulator motion system was used to present operators with a series of acceleration time histories which are representative of various shift strategies. The operators rated the relative comfort of each strategy during paired comparison tests. Limitations of the simulator motion system prevented definitive results from being drawn; however, results did confirm shift comfort criteria previously established by the machine manufacturer. Success of the Phase I effort was sufficient to warrant a more in-depth study. In Phase II a complete VPG environment for wheel loader operation on the IDS was developed and qualitatively evaluated. This VPG environment included a visual model of a mine pit, developed for Caterpillar, Inc. by engineers at its National Center for Supercomputing Applications office, combined with the immersive motion capability of the Iowa Driving Simulator. A real-time dynamics model of a generic wheel loader along with a menu driven interface to the data set used to simulate a particular wheel loader were developed at Center for Computer Aided Design. This combination of programs allows changes to the design of a loader to be rapidly evaluated within a virtual proving ground environment or off-line at an engineering workstation. The machine model was then combined with an implement/soil interaction model, also developed at Caterpillar’s National Center for Supercomputing Applications office. The resulting machine model can be evaluated either off-line at a workstation or driven in response to operator input within the Iowa Driving Simulator virtual proving ground environment. A comparison of the offline model’s predictions of machine response to swept-sinewave steering input is shown to compare favorably with measured performance of the actual machine.
