Streszczenie:

This paper presents an algebraic theory of instruction sequences with instructions for a random access machine (RAM) as basic instructions, the behaviours produced by the instruction sequences concerned under execution, and the interaction between such behaviours and RAM memories. This theory provides a setting for the development of theory in areas such as computational complexity and analysis of algorithms that distinguishes itself by offering the possibility of equational reasoning to establish whether an instruction sequence computes a given function and being more general than the setting provided by any known version of the RAM model of computation. In this setting, a semi-realistic version of the RAM model of computation and a bit-oriented time complexity measure for this version are introduced. Under the time measure concerned, semi-realistic RAMs can be simulated by multi-tape Turing machines with quadratic time overhead.

The article describes the role of play in child's development and identifies the characteristics of mature play in preschool age. The paper gives an overview of the computer games for preschool children used in Russian kindergartens. The research conducted with 50 Russian kindergarten teachers provides the analysis of the most important factors of computer programs selection made by teachers for their classroom activities. It is analyzed whether the factors concern the theory of children's play and whether the kindergarten teachers need the scaffolding program for choosing computer games appropriate for children's development. It is described the essence of the scaffolding program. They are formulated the criteria for evaluating computer games to make classroom activities developmentally appropriate.

Canonical triangulations provide an algorithm to compute the symmetry groups of hyperbolic links and their complements, along with information on how each symmetry acts on the link components. The latter information determines the chirality and invertibility of the link. Symmetry groups of knots to ten crossings and multicomponent hyperbolic links to nine crossing are listed, with some exceptions. A Macintosh computer program, available free of charge, computes symmetry groups interactively.

I developed an interactive computer program that allows one to demonstrate and experiment with various phenomena in visual perception using IBM-compatible computers. The program contains modules for demonstrating the color afterimage, the cafe illusion, additive color mixing and the opponent-process theory of color vision, the glowing axes illusion, the Hermann grid, the McCollough effect, the motion aftereffect, the neon illusion, and simultaneous contrast. The user has considerable control over the stimuli making up the image and can manipulate the variables that contribute to the perception of the effect. The program can be used far classroom demonstrations and student laboratory projects.

Streszczenie:

The study of type theory may offer a uniform language for modular programming, structured specification and logical reasoning. We develop an approach to program specification and data refinement in a type theory with a strong logical power and nice structural mechanisms to show that it provides an adequate formalism for modular development of programs and specifications. Specification of abstract data types is considered, and a notion of abstract implementation between specifications is defined in the type theory and studied as a basis for correct and modular development of programs by stepwise refinement. The higher-order structural mechanisms in the type theory provide useful and flexible tools (specification operations and parameterized specifications) for modular design and structured specification. Refinement maps (programs and design decisions) and proofs of implementation correctness can be developed by means of the existing proof development systems based on type theories.

Streszczenie:

This study reports on the possible role of the English Word Power (EWP) program in motivating ICT Foundation students to learn English at a University of Technology in South Africa. Current research indicates that computer-assisted language programs increase motivation and increase enjoyment of learning activities, but no study in South Africa has been conducted on whether this is the case with the EWP program. A qualitative approach was adopted. The sample comprised 44 purposefully selected student observations (n = 44); and five students completed journals. The findings from student observations indicate that they were enthusiastic about the program and that they enjoyed it. The findings from the journals show that students were unsure about certain instructions used in the program and they were too preoccupied with getting the correct answers. It is concluded that ICT Foundation students are positively motivated by the EWP program because, for most of them, learning by means of computers is a new experience in terms of their previous schooling backgrounds. This paves the way for further investigations in developing CALL programs that will have an impact on student learning. Future research should focus on whether similar computer-based programs like EWP do increase student learning.

It is well known that Jones polynomial (hence, Kauffman bracket polynomial) of links is, in general, hard to compute. By now, Jones polynomials or Kauffman bracket polynomials of many link families have been computed, see [4, 7–11]. In recent years, the computer algebra (Maple) techniques were used to calculate link polynomials for various link families, see [7, 12–14]. In this paper, we try to design a maple program to calculate the explicit expression of the Kauffman bracket polynomial of Montesinos links. We first introduce a family of "ring of tangles" links, which includes Montesinos links as a special subfamily. Then, we provide a closed-form formula of Kauffman bracket polynomial for a "ring of tangles" link in terms of Kauffman bracket polynomials of the numerators and denominators of the tangles building the link. Finally, using this formula and known results on rational links, the Maple program is designed.

The benefits of item response theory (IRT) analysis in obtaining empirical support for construct validity make it an essential step in the instrument development process. IRT analysis can result in finer construct interpretations that lead to more thorough descriptions of low- and high-scoring respondents. A critical function of IRT is its ability to determine the adequacy with which the attitude continuum underlying each dimension is assessed by the respective items in an instrument. Many nurse researchers, however, are not reaping the benefits of IRT in the development of affective instruments. The purpose of this article is to familiarize nurse researchers with this valuable approach through a description of the Facets computer program. Facets uses a one parameter (i.e., item difficulty) Rasch measurement model. Data from a survey of 525 new mothers that assessed the psychometric properties of the Postpartum Depresssion Screening Scale are used to illustrate the Facets program. It is hoped that IRT will gain increased prominence in affective instrument development as more nurse researchers become aware of computer programs such as Facets to assist in analysis.

The universal Turing Machine (TM) is a model for Von Neumann computers — general-purpose computers. A human brain, linked with its biological body, can inside-skull-autonomously learn a universal TM so that he acts as a general-purpose computer and writes a computer program for any practical purposes. It is unknown whether a robot can accomplish the same. This theoretical work shows how the Developmental Network (DN), linked with its robot body, can accomplish this. Unlike a traditional TM, the TM learned by DN is a super TM — Grounded, Emergent, Natural, Incremental, Skulled, Attentive, Motivated, and Abstractive (GENISAMA). A DN is free of any central controller (e.g., Master Map, convolution, or error back-propagation). Its learning from a teacher TM is one transition observation at a time, immediate, and error-free until all its neurons have been initialized by early observed teacher transitions. From that point on, the DN is no longer error-free but is always optimal at every time instance in the sense of maximal likelihood, conditioned on its limited computational resources and the learning experience. This paper extends the Church–Turing thesis to a stronger version — a GENISAMA TM is capable of Autonomous Programming for General Purposes (APFGP) — and proves both the Church–Turing thesis and its stronger version.

The underestimation of the value of supercomputing technologies has led Russia to fall behind in global trends, and squanders the enormous potential of Russian specialists in computer science. Russia needs a comprehensive supercomputer program, and cannot delay its enactment.

A physics theory predicts precise experimental results for some set of naturally occurring phenomena. Consequently, every well-formed physics theory is equivalent to a computer program that uses input descriptions of specific experimental setups to generate the outputs expected from those setups. The Kolmogorov complexity (or Kolmogorov minimum) of such a computer program is the program that uses the smallest number of bits to represent the largest possible of such input-output data pairs accurately. The principle of concise prediction asserts that the theory whose program length is shortest for a given set of experimental inputs and results is the one most likely to lead to deeper insights and new physics.

Using directstiffness method and theory of ACI 318-02, a numerical procedure along with a computer program was developed forthe structural analysis and design of reinforced concrete member. From the direct stiffness method,in terms ofstructural analysis, the output that obtained from the program are internal element forces and support reactions nodedisplacements. From ACI 318-02 codes, in terms of reinforced concrete member analysis, the program generate theamount of longitudinal and lateral reinforcement of concrete member based on the output in the previous structureanalysis program. The program also reveals the biaxial bending-axial interaction diagrams in each direction ofrectangular and circular column. The interaction diagram of the columns is a visual representation to determine themaximum axial load and moment exceeded the capacity of the column.

Abstract. According to the burmester theory, an infinite number of spherical or planar 4R linkages for a specific four-orientation task can be synthesized, but most of the linkage solutions calculated by this method are invalid because of motion defect, poor performance and others. In order to improve the synthesis efficiency, a program package based on Matlab is developed to find a satisfied linkage solution automatically and quickly. Firstly, the calculation on circle points and the center points based on the burmester theory in spherical problems is introduced. Secondly, the calculation methods of linkage defect discrimination, linkage type classification, linkage performance evaluation and solutions visualization based on the theory of spherical trigonometry are presented respectively. Thirdly, the synthesis calculation of program package is extended to the planar 4R linkage based on the theory of planar analytic geometry. Finally, the examples of the spherical synthesis problem and the planar synthesis problem based on solutions map are introduced to test the program package, the result proves this program package is effective and flexible.

The numerical integration (trapezoidal method) was used to compute the area under rotor performance curve, the program will record the value of this area, and by change parameter design and by knowing the maximum value of area, we will know the optimal design for turbine rotor. The three and four rotor blades and the values of design tip speed ratio between (5 - 9) give the best performance of rotor. The effect change of rotor radius on performance rotor was found very small, and there is no noticed effect to rated wind speed on rotor performance when changing parameter design in computer program

In this paper, we provide a translational semantics for these parameterized theories in first-order logic using the situation calculus.

Streszczenie:

This paper studies an extension of inductive definitions in the context of a type-free theory. It is a kind of simultaneous inductive definition of two predicates where the defining formulas are monotone with respect to the first predicate, but not monotone with respect to the second predicate. We call this inductive definition half-monotone in analogy of Allen’s term half-positive. We can regard this definition as a variant of monotone inductive definitions by introducing a refined order between tuples of predicates. We give a general theory for half-monotone inductive definitions in a type-free first-order logic. We then give a realizability interpretation to our theory, and prove its soundness by extending Tatsuta’s technique. The mechanism of half-monotone inductive definitions is shown to be useful in interpreting many theories, including the Logical Theory of Constructions, and Martin-Löf’s Type Theory. We can also formalize the provability relation “a term p is a proof of a proposition P” naturally. As an application of this formalization, several techniques of program/proof-improvement can be formalized in our theory, and we can make use of this fact to develop programs in the paradigm of Constructive Programming. A characteristic point of our approach is that we can extract an optimization program since our theory enjoys the program extraction theorem.

Recent critiques of and research with traditional alcohol prevention programs have revealed serious problems. Prevention programs typically increase knowledge and appropriate attitudes about alcohol while having little effect on drinking behavior. In this article several concepts are introduced in support of a technology which has the potential to revitalize alcohol education efforts. First, Bandura's self-efficacy theory offers a direction for re-conceptualizing the design of prevention programs as well as the measurement of their effects. Second, computer-assisted instruction (CAI) programs may provide a means for capturing attention, effectively educating about alcohol, and supplementing traditional approaches. One current CAI program is described in detail. Implications for research and practice and obstacles to effective CAI use are also discussed.

Magnetic islands in toroidal heliac stellarator vacuum fields are explored with Hamiltonian chaos theory and the associated area-preserving maps. Magnetic field line island chains are examined first analytically, with perturbation theory, and then numerically to produce Poincaré sections, which are compared with H−1 Heliac stellarator puncture plot diagrams. Rotational transform profiles are chosen to permit the comparison of twist map and nontwist map predictions with field line behaviour computed by a field line tracing computer program and observed experimentally.

The main achievements presented in this paper are developed method orientated on computer aiding and computer program method, both used in designing process of the new technical features. Analyzed methods develop algorithmisation of selection features and support integration with the process of the preparation of the production. Further analyses will be carried on in order to specify the theory of the technological similarity in the new forms of computer aiding (relational databases). The represented programs were being developed on the practical examples of creating the module systems of hydraulic cylinders used in mining, slag cars used in metallurgy and gears series of types. Programs and data bases presented in the paper are basis of selection of the technological features in the process series of types of the technology creating. All of these applications support the intensive development of the types of technical features and affect on their competitive on the ready market.

Although software tools already have a place on serial and vector computers they are becoming increasingly important for parallel computing. Message passing libraries, parallel operating systems and high level parallel languages are the basic software tools necessary to implement a parallel processing program. These tools up to now have been specific to each parallel computer system and a short survey will be given. The aim of another class of software tools for parallel computers is to help in writing or rewriting application programs. Because automatic parallelization tools are not very successful, an interactive component has to be incorporated. We will concentrate here on the discussion of SPEFY, a parallel program development facility.

This article reports on a new tool for optimized design of reinforced concrete plates based on the yield-line theory. The primary focus is on the development of a computer program which can analyze arbitrary yield-line systems with one degree of freedom. The program includes a GUI for quick and intuitive input, and automatically performs analysis of yield-line systems regardless of the complexity of their analytical solution. Furthermore, optimization of orthotropic reinforcement is implemented. The possibility of yield-line analysis of systems with multiple degrees of freedom by linear programming is examined.

Because the embedded computer performance evaluation indexes are uncertainty, the better method of embedded computer performance evaluation is proposed by applying the set pair analysis theory. First, identical degree, different degree, and contrary degree are respectively determined by the optimal program, intermediate program and worst program, and the weight of performance evaluation indexes are determined by order relation analysis. Finally, the weight contact coefficient is obtained, and the sort of embedded computer performance is determined by situation of weight contact coefficient. The experimental results show that this method can effectively evaluate the embedded computer performance, and the evaluation results are in line with the actual situation.

microScope for Windows™ is a transmission electron micrograph simulation program for brightfield and darkfield images of dislocations and stacking faults, based on the dynamical two-beam theory and the column approximation. The program is a modification of the original programs of Head et al, which have been rewritten in Visual Basic™ 4.0 for Microsoft® Windows™ 3.1. microScope for Windows™ also includes routines needed to prepare data for the actual calculation of the image, and to calculate and display a rocking curve for any pixel of the previously computed brightfield or darkfield image. On a 120 MHz Pentium, microScope for Windows™ calculates a true gray scale (256 gray level) image consisting of 19840 pixels in about 10 seconds (version 2.3). A 300 dpi laserprinter screendump at the end of the calculation of an image is shown in Fig. 1.

We give a rigorous framework for the interaction of physical computing devices with abstract computation. Device and program are mediated by the non-logical representation relation ; we give the conditions under which representation and device theory give rise to commuting diagrams between logical and physical domains, and the conditions for computation to occur. We give the interface of this new framework with currently existing formal methods, showing in particular its close relationship to refinement theory, and the implications for questions of meaning and reference in theoretical computer science. The case of hybrid computing is considered in detail, addressing in particular the example of an Internet-mediated social machine , and the abstraction/representation framework used to provide a formal distinction between heterotic and hybrid computing. This forms the basis for future use of the framework in formal treatments of non-standard physical computers.

The medicine is weakly formalized domain, and preliminary study of knowledge structure is necessary for computerlearning programs development. Semantic network can be offered as an universal knowledge model for higher medical education. The links between nodes reflect their semantic distance. Graph theory is an adequate tool for knowledge structure investigation, and the results of one prove knowledge models for certain domains and optimal navigation through the program. The last depends on personal features of students, too. So, the basic principles for computer learning programs development in higher medical education are knowledge structure modeling and individual learning navigation.

Streszczenie:

Distance learning presents great potential for mitigating field problems on pesticide application technology. Thus, due to the lack of teaching material about pesticide spraying technology in the Portuguese language and the increasing availability of distance learning, this study developed and evaluated a computer program for distance learning about the theory of pesticide spraying technology using the tools of information technology. The modules comprising the course, named Pulverizar, were: (1) Basic concepts, (2) Factors that affect application, (3) Equipments, (4) Spraying nozzles, (5) Sprayer calibration, (6) Aerial application, (7) Chemigation, (8) Physical-chemical properties, (9) Formulations, (10) Adjuvants, (11) Water quality, and (12) Adequate use of pesticides. The program was made available to the public on July 1st, 2008, hosted at the web site www.pulverizar.iciag.ufu.br, and was simple, robust and practical on the complementation of traditional teaching for the education of professionals in Agricultural Sciences. Mastering pesticide spraying technology by people involved in agricultural production can be facilitated by the program Pulverizar, which was well accepted in its initial evaluation.

Abstract Predicate intuitionistic logic is a well-established fragment of dependent types. Proof construction in this logic, as the Curry–Howard isomorphism states, is the process of program synthesis. We present automata that can handle proof construction and program synthesis in full intuitionistic first-order logic. Given a formula, we can construct an automaton such that the formula is provable if and only if the automaton has an accepting run. As further research, this construction makes it possible to discuss formal languages of proofs or programs, the closure properties of the automata and their connections with the traditional logical connectives.

Streszczenie:

Technological advances in computer science have secured the computer metaphor status of a heuristic methodological tool used to answer the question about the nature of mind. Nevertheless, some philosophers strongly support opposite opinions. Anti-computationalism in the philosophy of mind is a methodological program that uses extremely heterogeneous grounds for argumentation, deserving analysis and discussion. This article provides an overview and interpretation of the traditional criticism of the computational theory of mind (computationalism); its basic theses have been formed in Western philosophy in the last quarter of the 20th century. The main goal is to reveal the content of the arguments of typical anti-computationalist programs and expand their application to the framework of the semantic problems of the Classic Computational Theory of Mind. The main fault of the symbolic ap-proach in the classical computationalism is the absence of a full-fledged theory of semantic properties. The relevance of considering these seemingly outdated problems is justified by the fact that the problem of meaning (and general problems of semantics) remains in the core of the latest developments in various areas of AI and the principles of human-computer interaction.

The garbage can theory of organizational choice is one of the best-known innovations in modern organization theory. It also has significantly shaped a major branch of the new institutionalism. Yet, the theory has not received the systematic assessment that it both deserves and needs. We evaluate the early verbal theory and argue that it fails to create an adequate foundation for scientific progress. We then analyze and rerun Cohen, March, and Olsen’s computer model and discover that its agents move in lockstep patterns that are strikingly different from the spirit of the theory. Indeed, the simulation and the theory are incompatible. Next, we examine how the authors have built upon these incompatible formulations in developing the theory further. We assess this larger program, which includes the March-Olsen version of the new institutionalism, and find that many of the problems that attended the original article have intensified over time. We conclude that a fundamental overhaul is required if the theory is to realize its early promise.

Streszczenie:

A computer simulation of the motion of ions in a three-dimensional (3-D) quadrupole ion trap has been performed with a Gateway 386 PC/AT computer. The SIMION program was used as the main program to calculate the potential array of the ion trap space. Several user-written programs were interfaced to the SIMION program to simulate the effects of changing various operating conditions, such as the radio-frequency (rf) potential, the collisional buffer gas, external ion injection, dc ejection from the trap, and resonance ejection. With the use of this simulation, the total storage mass range could be obtained as a function of rf voltage and frequency. The simulations show, as expected, that the collisional buffer gas plays an important role in both stabilizing the trajectory of high-kinetic-energy ions (hot ions) inside the ion trap and trapping ions injected from an external source. Several different buffer gases were studied for their effects upon the trapping motion. In addition, both the total mass ejection that results from applying a dc pulse on the output end-cap electrode and the ion ejection that results from applying an rf frequency to the end cap to produce resonance ejection were also studied with this simulation program. It is demonstrated that a simple PC computer using a modified SIMION program provides results very similar to those expected from theory or from previous work.
