W artykule przedstawiono proces optymalizacji postaci geometrycznej głowicy tnącej obrabiarki water-jet z wykorzystaniem oprogramowania ANSYS Workbench. Celem badań było sprawdzenie jaki wpływ mają zmiany poszczególnych wymiarów na zmianę parametrów przepływu strugi wodno-ściernej. Analiza statystyczna wyników pozwoli ograniczyć stopień skomplikowania modelu w późniejszych badaniach zbiorczych poprzez...
Paper presents a research related to the design of a new concept of hybrid energy system. It describes actually used concepts and the benefits of new design. Subsequently, the problems of the proper systems setting and working conditions are discussed and the new concept of the systems settings is presented. Research is further enhanced by comparing with the simulation model assuming the weather data...
Paper concerns the software system supporting the analysis of different cases of solving VRP by various algorithms. VRP has been characterised and application structure has been presented. Illustrative experimental results show the usefulness of the system.
The article presents a discussion of the optimisation methods involving the modification of query syntax on the example of the use of indexes that served for the application of the methods in practice, and the presentation and analysis of the test results and their comparison. All the queries were made in a Microsoft SQL Server Management Studio 2014 environment, using the AdventureWorksDW2012 test...
The maximum subarray problem (MSP) is to the find maximum contiguous sum in an array. This paper describes a method of Kadanes algorithm (the state of the art) optimization for specific data (continuous sequences of zeros or negative real numbers). When the data are unfavourable, the modification of the algorithm causes a non significant performance loss (1% > decrease in performance). The modification...
The paper discusses the practical aspects of application of multicriterion approach to solving the problem of an optimal routing for wireless selforganizing networks. As the initial metrics analyzed convergence time, memory overhead, control overhead, time complexity and communication complexity.
The article deals with the synthesis of an optimal digital controller for a stochastic plant. In order to optimize the control system, an integral quality criterion together with minimization of the controlled parameter variance that is offered here, besides the control actions the control objects are taken into account. Using the methods of optimization theory for a single-loop control system, the...
The paper is devoted to questions of technological fatigue life assurance of parts working in conditions of cyclic loads by optimization their cutting conditions for finish turning process. In order to solve the task of optimizing the parts cutting conditions, the corresponding software, based on the previously created mathematical model of the finishing turning process, was developed in the C# programming...
