Abstract In this paper, the integration infrastructure for a simulation-based design (SBD) environment for mechanical system design developed at Center for Computer-Aided Design at the University of Iowa is presented. The SBD environment comprises the integration infrastructure and workspaces/tools that exploit Computer Aided Design (CAD)/Computer Aided Engineering (CAE) and software engineering technologies in support of design of large scale mechanical systems. The principal functional components of the SBD environment are engineering workspaces and CAD/CAE tools that bring engineers, servicemen, and customers early in the product development process to assess design of the product concurrently. The infrastructure is based on the newly invented engineering views that allow engineers from various disciplines to view the product with their own perspectives. The infrastructure allows engineers to create CAD and simulation models of the mechanical system, access engineering workspaces and CAD/CAE tools to perform multidisciplinary engineering analyses, use planning tools to create and manage simulation processes, communicate and exchange engineering data, and conduct design trade-off analyses and make informed decisions to yield a robust optimum design. The presentation given in this paper assumes that simulation-based design activities are performed in the product detailed design stage. The environment is being extended to support concept design.

The speed and specializations of large-scale integrated circuits always contradict their versatility, which expands their range and causes the rise in price of electronic devices. It is possible to eliminate the contradictions between universality and specialization by developing programmable nanoelectronic devices, the algorithms of which are changed at the request of computer hardware developers, i.e. by creating arithmetic circuits with programmable characteristics. The development of issues of theory and practice of the majority principle is now an urgent problem, since the nanoelectronic execution of computer systems with programmable structures will significantly reduce their cost and significantly simplify the design stage of automated systems. Today there is an important problem of developing principles for building reliable computer equipment. The use of mathematical and circuit modeling along with computer-aided design systems (CAD) can significantly increase the reliability of the designed devices. The authors prove the advantages of creating programmable nanodevices to overcome the physical limitations of micro-rominiatization. This continuity contributes to the accelerated introduction of mathematical modeling based on programmable nanoelectronics devices. The simulation and computer-aided design of reliable programmable nanoelectronic devices based on the technology of quantum automata is described. While constructing single-electron nanocircuits of combinational and sequential types the theory of majority logic is used. The order of construction and programming of various types of arithmetic-logic units is analyzed.

Постановка задачи. Для получения оптимальных проектных решений, удовлетворяющих условиям безопасности движения в сложных погодных условиях, необходимо сравнение вариантов автомобильных дорог по условиям снегонезаносимости. Такие расчеты должны стать составной частью системы автоматизированного проектирования САПР-АД. Результаты. Предложен системный поход к решению задачи, определен перечень информации, необходимой для проведения расчетов. Выполнен анализ результатов исследований по снегозаносимости дорог, проводимых в России и за рубежом. Предложены расчетные схемы и модели для оценки вариантов продольного профиля и земляного полотна автомобильной дороги по снегозаносимости. Предложены решения для оценки вариантов плана трассы с использованием карт с расчетными параметрами метелей. Выводы. Реализация предложенной методики проведения расчетов позволит на стадии проектирования оценить варианты автомобильной дороги по условиям снегозаносимости. Statement of the problem. In order to obtain optimal design solutions that meet the conditions of safety traffic in difficult weather conditions, it is necessary to compare the options of highways according to the snow tolerance conditions. Such calculations should become an integral part of the CAD-AD computer-aided design system. Results. A systematic approach to solving the problem is set forth, a list of information necessary for calculations is identified. The results analysis of studies on the snow-bearing capacity of roads conducted in Russia and abroad is carried out. Calculation schemes and models are suggested to evaluate options for the longitudinal profile and the roadbed for the snow-bearing capacity. Solutions for evaluating variants of the route plan using maps with calculated parameters of snowstorms are proposed. Conclusions. The implementation of the proposed calculation methodology will make it possible at the design stage to evaluate the options of the highway according to the conditions of the snow-bearing capacity.

As the flourishing of computer technology and the appearing of lots of large-scale and well-designed corpora and concordance software, corpus-based approach, an advanced teaching resources, has been widely employed in language researches of various fields and perspectives. English teaching material, the main source of language input, has the quality and authority in Chinese English language teaching classes. The present study attempts to bring about some innovations in construction and designing of teaching material on the basis of the Corpus of Contemporary American English (COCA). Moreover, the research is intended to effectively improve teacher’s input and introducing data-driven learning (DDL), and to effectively stimulate the motivations of students by using this computer-aided and COCA-based designing.
