Earlier or later, the use of fossil fuels will become impossible but the need for electric power will increase. Naturally, renewable energy sources will be a single alternative despite the cost of electricity. Unpredictability and intermittent attribute of renewables can be surpassed using the random nature of these sources with the help of a powerful intracontinental power line that collects energy from renewable sources (wind farms and others) scattered over large area. At the local level, the higher the voltage class, where renewables with sufficient disunity are injected, the more they are imperceptible to customers. The customer which gets larger share of renewable energy should participate more in demand side integration and energy storage.

This paper deals with the question about the most efficient and less energy consumptive type of low-voltage DC-DC converter. Different types of DC-DC converters (Synchronous buck-boost, Cuk, Zeta, Sepic etc.) are analyzed in terms of low voltage implementation. The comparison of energy consumption of different types of converters is given. Different examples of such converter implementation are examined — for example, low voltage DC-DC converters can be used as power converter in photovoltaic system, or, for example, as charging converter for batteries. Different physical models of such implementations are presented — a model with small amount of photovoltaic cells, and a model where DC-DC converter is used as a charging converter for batteries for a power wheelchair, or for example, for battery used to power prosthetic limbs (hands, legs etc.).

Transport travel demand models allow one to estimate future traffic changes after the changes in the functionality of a building object has been made and to identify the potential bottlenecks of transport system. The paper contains a use case on transport travel demand model development based on decision tree algorithms and simulation methods. Decision tree algorithm that has flexible structures suitable for representing the relationships between the categories of transportation modes and do not require any knowledge about the initial specific model data structure was used in transportation mode choice. Transport travel demand simulation model was developed for mixed-use building in the area of Hanzas Street (Riga city, Latvia).

The proposed approach includes risk management model which quantifies risks, based on actual threats and balances it with academic freedom that every academic environment employs. Preventive IT security measures that could be taken and solutions to improve IT security in academic environment are discussed in this paper.

In this paper the computer model of the high voltage, high frequency submicrosecond electric field generator for electroporation of biological objects is presented. This paper addresses the problem of the impact of parasitic circuit elements and minimization of the transient processes during sub microsecond high voltage pulses. Using SPICE simulation software, the influence of the parasitic electrical circuit elements to the generated electric field pulse are analyzed. The transient processes damping circuit using controlled crowbar and RC snubber circuits are proposed.

Energy saving importance is growing year-to-year and effective lighting is considerable part of overall consumption reduction. Modern light sources (LED based lamps) are much less consuming than traditional ones. Furthermore, the saving can be increased, by implementing smart lighting control systems over theses lamps. High initial costs set investment bounds on wide use of systems of this kind. The main elements that give LED lamp smart functionality are: 1) dimmable driver; 2) communication module; 3) sensor/s (ambient light, movement, gas etc.); 4) controller. This paper gives the insight on cost reduction by integration of microwave motion sensor in LED lamp to build a smart system.

The automatic receipt analysis problem is very relevant due to high cost of manual document processing. Therefore, the presented paper investigates the problems of receipt image analysis. It describes approaches for receipt image pre-processing, receipt text detection, receipt text recognition and receipt text analysis. These approaches allow to make receipt analysis system adaptable for a real-life environment and to convert the input information to a usable format for analysing information in the receipts. A pipeline for payment data processing staring with image capture to payment data posting is defined and appropriate technologies for every stage of the process are proposed. Advantages and limitations of these technologies are reviewed and open research challenges are identified. The payment data processing is analyzed as an enabler of digital transformation of expense reporting processes.

Consumption time of stereoscopic content is increasing with the new technologies being introduced to the market, visual comfort in viewing stereoscopic images and videos is currently a subject of very high importance. Different stereoscopic viewing techniques, e.g. head mounted displays, stereoscopic monitors and projectors and large cinema screens requires individual setups for comfort image perception. The aim of the investigation, presented in this paper is to indicate measurable features of the eye activity which may correlate with visual discomfort during stereoscopic perception. In addition, a technique for focus moment identification was proposed that is based on real-time measures of eye activity. 120 stereoscopic images of publicly available dataset which had subjective evaluation of visual discomfort was shown until participants indicated they have had focused on shown stereoscopic content Pupillometric and gaze data of subjects were collected using eye tracker. Measured data shows a distinct constriction of pupil diameter, when subjects were exposed to the stereoscopic content, followed by a dilation, half of initial pupil size, until subjects indicated the time of focus. Based on these findings afore mentioned focus moment identification technique was proposed. Also, our findings of pupil dilation agrees with existing research where relationship was found between cognitive activity and pupil dilation.

The series of experiments is devoted characterisation of 600 V, 85 A RB IGBT devices under hard and soft switching conditions using a double-pulse test circuit. The switching behaviour, particularly turn-on and turn-off characteristics, of these devices under various conditions are evaluated. Obtained results allow to assess the impact of reverse recovery process on the turn-on losses and compare the characteristic of RB IGBTs with various types of discrete diodes.
