The article presents an algorithm for selecting an electric vehicle for your photovoltaic system. Generating electricity by distributed photovoltaic systems is a very visible trend across Europe. Individual and institutional owners are looking for opportunities to save large amounts of money spent on the purchase of electricity. Many times they have built a photovoltaic system larger than their current energy needs. The author suggests a solution to increase the energy produced for own needs instead of giving it to the power grid at unfavourable prices. Such a solution is the purchase of an electric vehicle that will be charged with surplus energy. Research on the selection of a vehicle for a photovoltaic system should start with a precise profile of the current energy consumption from the power grid, energy production from the photovoltaic system and transferring its excess to the power grid. The next step is to characterise the potential electric vehicle. Such characteristics include the determination of the energy capacity of the traction battery and the methods of its charging. The final stage is the analytical confirmation of the choice made. For this purpose, the Metalog family of distributions was used to determine the probability of generating the appropriate hourly amount of energy needed to charge an electric vehicle.

The article presents a method of a photovoltaic system power selecting for proper electric vehicle. At the beginning, the characteristics of the electric vehicle itself and its traction batteries were made in order to determine the method of its charging. In the presented studies, measurement data from the operation of real photovoltaic systems was recorded and processed. The algorithm used includes examining the energy consumption profile of the owner's residential building. The combined demand for electricity of the electric vehicle and the building made it possible to determine the planned photovoltaic system. The authors presented three possibilities of its location. It can be installed on the roof of the building, on the ground next to the building or on the carport under which an electric vehicle can be parked. Finally, the Metalog family of probability distributions was used to analytically validate the power choice of the photovoltaic system. The authors have developed an algorithm using human and artificial intelligence that helps to properly select the power of the photovoltaic system for the vehicle.

This article presents the ultrasonic structure for the analysis of technological processes in the field of reflective and transmission waves. Ultrasound tomography enables the analysis of processes occurring in the examined object without interfering with its interior through appropriate acquisition and analysis of data. The design goal is to verify the repeatability of measurement results by eliminating laboratory equipment. The ultrasonic tomograph has been designed in a modular way and consists of a motherboard connected to an analog signal conditioning board, a liquid crystal display with an integrated graphics processor and a high voltage pulser with a 64 channel multiplexer. The solution was designed for tomographic measurements of technological process properties.

W niniejszym artykule przedstawiono konstrukcję tomografu ultradźwiękowego do analizy procesów technologicznych w zakresie fal odbitych i transmisyjnych. Tomografia ultradźwiękowa umożliwia analizowanie procesów zachodzących w badanym obiekcie bez ingerencji w jego wnętrze poprzez odpowiednią akwizycję i analizę danych. Celem konstrukcyjnym jest weryfikacja powtarzalności wyników badań pomiarowych poprzez wyeliminowanie sprzętu laboratoryjnego. Tomograf ultradźwiękowy został zaprojektowany w sposób modułowy i składa się z płyty głównej połączonej z płytą kondycjonowania sygnału analogowego, wyświetlacza ciekłokrystalicznego ze zintegrowanym procesorem graficznym oraz impulsatora wysokiego napięcia wraz z 64 kanałowym multiplekserem. Urządzenie zostało zaprojektowane do tomograficznych pomiarów właściwości procesów technologicznych.

The paper presents an application of Graph Data Base technology in knowledge engineering task concerned with knowledge representation of complex structures. The first example is graph representation of a composition of tractor gearbox. It is an example of application of static partonomy relation. The adequate codding of that relation in Graph Data Base is easily expressed in Cypher language. There were presented some applications of Graph Data Base useful in the management of the technical object existence in different “life” phases, as design, production, maintenance and recycling. The second example concerns the Graph representation of activity structure. Such structures were built based on an agricultural tractor’s technical revision system. Created Data Base allows for processing the queries referred to the questions of what activities in what period should be performed to maintain the agricultural tractor ready to work in good technical condition. The Graph Data Base technology is the first step to create semantic systems for data storing and processing in order to extract knowledge and information useful in precise physical process management.
