This paper develops the approach to determine the stability of control object, which is an important step in the selection process of fractional controller parameters during its robust synthesis of desired quality of the transition process. The research of transfer functions of electromechanical systems on the stability of fractional order differs from traditional systems. The method of approach to the definition of stability suitable for stability analysis of electromechanical systems, described by transfer functions of both fractional and integer order, has been examined. Informative parameter for quality control and stability of electromechanical systems has been established, which allows to obtain information about the stability, oscillation and the quality of the transition process of an output coordinate of electromechanical system in the first approximation.Item Analysis of the process of obtaining methyl esters of fatty acids from waste vegetable oils(Lviv Polytechnic Publishing House, 2015) Kukushkina, Olena; Vasylkevich, Oleksandr; Bondarenko, Sergiy; Beznosyk, Yuriy; Kyiv Politechnic InstituteThe technological features of the process of obtaining the methyl esters of carboxylic acids from renewable materials were analyzed.

Actuality of this issue consists in the necessity to take account of the driver’s type of temperament as the main road traffic participants, which is one of the key factors of any behavior in difficult traffic situations.Item Application of basic tools of experimental economy in management science(Lviv Polytechnic Publishing House, 2015) Joachimiak, Izabela; Wroclaw University of EconomicsIn the times of rapid economic transformations taking place in the world markets, it is becoming more and more difficult to predict economic trends as well as people’s behaviour. In order to do so, it is more common nowadays to adopt unorthodox approach apart from using traditional methods. Undoubtedly, experimental economy is a good example of such kind of approach. The basic tool used in experimental economy is an experiment and it will be the main subject of this study. In its first part, this article explains fundamental concepts and the essence of experimental theory basing on available literary resources. The second part presents lots of specific examples showing how to use experiments both in human resources management and quality management.Item Attitude towards psychological knowledge in Ukrainian society(Lviv Polytechnic Publishing House, 2015) Kuta, Oksana; Lviv Polytechnic National UniversityThere are a lot of problems in Ukrainian science. Old fashioned educational programs and students who are not interested in personal growth and professional development are some of them. We believe that all these results in misunderstanding and mistrust to the psychological science in Ukraine. People of different age might use psychological knowledge in everyday life more often – in case of solving personal difficulties problems or for improving quality of life. The results of empirical study of use of psychological knowledge among ordinary people are presented.Item Automation of prototyping the pattern tests from an electronic compendium of lectures(Lviv Polytechnic Publishing House, 2015) Markelov, О.; Basalkevych, О.; Lviv Polytechnic National UniversityThe main goal of this work is to create the algorithmic core for the system of prototyping the pattern tests from the electronic collection of lectures. Basic similar software products are reviewed to prove the appropriateness of further development. The structure and format of input and output program files are explained. Principles of program operation and internal data representation are clarified. Information, linguistic and program supports have been evolved within the frameworks of the system realization.Item Automatization design of the user interface based on the knowledge that describes ontology(Lviv Polytechnic Publishing House, 2015) Zavuschak, Iryna; Burov, Eugene; Lviv Polytechnic National UniversityThe paper describes some approaches to UI design automation based on the knowledge that describes ontology domain. Tools interface development based on ontologies software, based on the principle of separation of designing and implementing the user interface and business applications and their subsequent binding and automatic code generation interface for its model. To develop the proposed ontology, in terms of which UI developers form the corresponding components of his model; generation interface is more programming languages on different platforms; supports both local and network interaction with business applications; Model interface is divided into components according to groups of professionals engaged in its development (subject area experts, programmers, designers) and contains all the information necessary for its development and automatic generation according to the model.Item Basic principles of low-rise residential floating buildings design(Lviv Polytechnic Publishing House, 2015) Shekhorkina, Svitlana; State Higher Education Establishment “Pridneprovsk State Academy of Civil Engineering and Architecture”Floating building is a complex engineering structure, which combines functional features of typical homes and vessels.

Microsized nanostructiral particles were characterized by SEM, aerosol spectrometry and pharmaceutical impactor. Results show that proper adjusting of SD process parameters and precursor composition allows to obtain powders of different morphologies: solid or hollow particles with different wall thickness, or particles with a microporous structure with spherical or nonspherical shape. Obtained results indicate that silica nanoagreggates have characteristics suitable for their effective delivery to the lungs via inhalation.Item City’s parameters influence on transportation servicing of goods(Lviv Polytechnic Publishing House, 2015) Fiyalko, Nataliya; Galkin, Andrii; O. M. Beketov National University of Urban Economy in KharkivProduction delivery in the consumption sphere is one of the important trade functions that take place in the commercial companies.
