Set Of Functional Elements Research Articles

Strategic development methodologies — a systematic approach

Strategic development is presented as an organic set of functional elements — development strategies at successive time intervals of development and their connections. Strategic planning of an organization is presented as a set of individual functional elements and their links, focused on achieving the goal. From an organizational point of view, strategic planning is presented as a time-structured project that develops over time and contains a strict sequence of elements (stages). Financial planning is an infrastructural element in the strategic planning system. The basic principles on which the methodology of the project presentation of the strategic development of the organization is based as a systematic way of economic thinking are formulated.

System Analysis and Solution of Energy Efficiency Problems in Machine-Building Production

The article discusses application of system analysis to identify and solve the problems of energy efficiency of machine-building enterprises. The increase in the efficiency of a machine-building enterprise is influenced by many factors, among which tariffs and prices for energy services have a significant impact. The increase in tariffs for these services has a direct impact on the increase in cost. Energy efficiency objectives also include: high energy capacity of products; insufficient efficiency of generation, transportation and distribution of energy resources; low reliability of power supply; insufficient volume or low reliability of information on the energy infrastructure operation. As a result of the system analysis, directions have been identified that enable one to increase energy efficiency, which leads to a decrease in the cost of production, and, consequently, to an increase in the profit of the enterprise. Directions for increasing the energy efficiency of machine-building enterprises can be identified as a result of system studies of the activities of all divisions of the main, auxiliary and service industries. The greatest effect from energy-saving measures is achieved in the process of rational energy consumption, which is advisable to implement at machine-building enterprises. Reduced production output caused by the global economic crisis that began in 2008 and the impact of the 2020-2021 pandemic have resulted in the equipment operation at reduced loads and in off-design modes, which in turn has led to the auxiliary equipment consuming almost the same amount of energy as at nominal performance. This circumstance leads to an increase in costs. A mathematical model has been developed, in which a machine-building enterprise is considered as a set of functional elements and components with a hierarchical structure of connections between them, described in the form of a ‘6-tuple’.

Integrated form of the waveguide circuits in the terahertz range

Problem statement. The successful development of the terahertz range is inextricably linked to the creation of effective guide systems with the required characteristics, as well as a complete set of functional elements. Known guide systems of the specified range for several reasons do not allow creating a complete set of functional elements and circuits for various purposes. In this paper, the authors consider the principles of creating modular waveguide circuits based on a metaldielectric waveguide.Objective. Study of the issues of creating waveguide circuits for various purposes in an integrated design. The choice of a square-section metal-dielectric waveguide is justified to solve this problem. The absence of surface currents on the walls of this waveguide dramatically reduces energy losses at the joints and flange connections. This allows for creating integrated circuits as a single module. A diagram of the high-frequency part of a monopulse locator made by pressing in plastic is given as an example.Results. It is shown that the studied design of the circuits excludes flanged connections between waveguide elements, thereby reducing losses in the connections between various functional elements, which reduces the total losses in the circuit. Experimental results are presented.Practical implications. A technology for integrated design of ultra-high-frequency terahertz circuits based on a metaldielectric waveguide, excluding flanged connections between functional elements, is proposed. This waveguide and the functional elements provide the development of various circuits for operation at high powers.

Specifications of insilicoML 1.0: A Multilevel Biophysical Model Description Language

An extensible markup language format, insilicoML (ISML), version 0.1, describing multi-level biophysical models has been developed and available in the public domain. ISML is fully compatible with CellML 1.0, a model description standard developed by the IUPS Physiome Project, for enhancing knowledge integration and model sharing. This article illustrates the new specifications of ISML 1.0 that largely extend the capability of ISML 0.1. ISML 1.0 can describe various types of mathematical models, including ordinary/partial differential/difference equations representing the dynamics of physiological functions and the geometry of living organisms underlying the functions. ISML 1.0 describes a model using a set of functional elements (modules) each of which can specify mathematical expressions of the functions. Structural and logical relationships between any two modules are specified by edges, which allow modular, hierarchical, and/or network representations of the model. The role of edge-relationships is enriched by key words in order for use in constructing a physiological ontology. The ontology is further improved by the traceability of history of the model's development and by linking between different ISML models stored in the model's database using meta-information. ISML 1.0 is designed to operate with a model database and integrated environments for model development and simulations for knowledge integration and discovery.

Developing an HLA Virtual Command Post

SRI International and Lionhearth Technologies have been developing an HLA-compliant version of the Virtual Command Post (VCP), a distributed simula tion in which users interact and share battlefield in formation. The project involves developing HLA federates for individual functional VCP capabilities. The goal is to develop an HLA-compliant VCP as a stand-alone federation, as well as a set of functional elements that can interact as separate HLA federates in other federations. As a federate, the VCP can par ticipate in federations requiring a command, control, communications, computers, and intelligence feder ate. The individual VCP federates can act as sepa rate elements in other federations. Among issues examined is run-time infrastructure (RTI) perfor mance sending high-volume audio and video data. We are now examining the H-Anim standard for representing human commanders. We have found that the HLA and the RTI are capable of meeting our functional requirements for a distributed simula tion. We also believe we can develop an HLA-com pliant simulation that will promote its use in HLA federations. This paper describes the HLA VCP, the experiments and results we have obtained to date, and efforts we have planned for the future.

RANDOM PROCESSES GENERATED BY A HYPERBOLIC SEQUENCE OF MAPPINGS. II

This paper is a direct continuation of [1]. It contains proofs of the theorems announced there on the existence of invariant classes of functional elements and functional deformations for a hyperbolic sequence of mappings, as well as theorems on the existence of invariant cones in spaces of regular functions defined on a set of functional elements.
