This paper presents a completely renewed technique developed to locate single parametric faults in analog circuits by means of multi-frequency measurements or simulations, following a rigorous approach. The technique is composed by three separated stages, a first one which evaluates the testability and ambiguity groups of the Circuit Under Test (CUT), a second one which localizes the fault classifying it in an appropriate Fault Class (FC) and a last one (optional) that can extract the value of the faulty component. The manufacturing tolerances of the healthy components are taken into account at each stage of the method.

Agent based modelling is a paradigm that is widely used to simulate and research systems where each entity is autonomous and behaves independently. Currently, there are many diverse agent based models, however, aside from general guidelines there are no particular analysis of how such models should be designed and implemented. On the other hand, any agent based model can be broken into a single agent and a system level; these abstraction levels are used in the design of multi-agent systems, moreover, agent based models are often implemented using mechanisms and tools from multi-agent systems. Author proposes that one of the ways this problem could be solved is classification of agent-based models from the perspective of multi-agent systems which is then used to provide decision support for the design of agent-based models.

A power supply design has been suggested and examined for high current, low duty-cycle pulsed loads, specifically — aluminum spot welding inverters. Through the use of energy storage the power supply design aims at an input current that is equally distributed through time, thus preventing grid connection over-dimensioning and avoiding transient stresses to the grid. A converter topology has been proposed for controlled charging and discharging of a capacitor bank. The performance has been verified through simulation using Matlab Simulink. A scaled prototype of the capacitor discharge converter has been assembled and tested. Experimental results show that high energy controlled capacitor discharging is possible with the chosen methods.

This paper present an experimental comparison study of the distance protection operation during metallic earth faults, earth faults with constant fault arc resistance and faults with constant fault arc resistance and additional transient ground path resistance. The aim of this study is to recreate “in vitro” conditions when distance protection maloperated during fallen tree fault. Such earth faults are more common in the region and they are known as “weak points” of distance protection. The tests were performed by simulating the faults in MATLAB SimPowerSystems environment. The obtained transient waveforms of currents and voltages were then comtraded to ISA TDMS system, via which the output signals, provided to the digital relays, were generated. As a result an environment for testing of distance protection performance during fallen tree faults was created. This provides an opportunity to find possible errors of the existing distance protection algorithms and develop more robust ones.

Nowadays drones and RC planes come more and more popular since they are widely available. People enjoy filming from drones even in drone strictly forbidden places ignoring prohibition signs. That often makes problems for specialists working in an environment with demanded radio emission free zone. To avoid drones from flying in prohibited areas a drone radar is needed. This paper represents feasibility study on passive radar for drone detection using novel signal processing technique and Monte Carlo method. Radar simulation was made to study impact of different factors on the drone detection quality simulating different antennas setups: regular and irregular placement of the antennas, similar and different directivity antennas, stationary and randomly pointed antennas. Results show the impact of different drone quantity, antennas directivity, antennas placement, antennas rotation on the drone detection quality.

In acoustics, loudness is the subjective perception of sound pressure. Loudness control systems involving loudness control algorithms are used in radio and television broadcasting. In this paper we present a research on the influence of attack and decay parameters on the performance of loudness control algorithms. Attack and decay are temporal parameters of the algorithm, that define the rate at which the algorithm applies the correction to the audio material. For this investigation, a relatively simple real time loudness control algorithm was devised, having only the two parameters: the attack and the decay rate of the algorithm's reaction. The input signal for the algorithm is the weighted sum of the loudness measurements of the source material the in three temporal scales, as per EBU R-128 recommendation. Experiments were conducted with various summing weights of the input signal. The test sound material was acquired from actual commercial TV broadcast. The performance of the algorithm were evaluated by measuring differences of three parameters of the corrected material before and after the correction as a function of the attack and decay values: the loudness range, overflow percentage, and average integrated loudness level.

The present research is devoted to the current problem of train control automation, which represents one of the trends of development of international transport. The proposed approach is aimed to overcome the drawbacks of existing train autodriving systems and provide the model-algorithmic basis for unified train control automation. The corner stone of this approach are the mathematic iterative optimization methods considering restrictions and assuring optimal solution for the multicriteria optimization problem.

Nowadays, in all modern electronic devices a low voltage with high speed comparator plays an important role in overall performance of the systems. This paper describes the implementation of a high-speed comparator with high-resolution, 10-bit, in 0.18pM CMOS technology drawn from a 1.8 V supply which is suitable for analog-to-digital converter (ADC) applications and for electronic industry. An offset cancellation technique is done and tested in order to decrease the offset and kickback noise. Regarding the Monte Carlo and corner simulation results for 100 samples and 9 corners respectively, it can be observed that bit error rate is approximately zero and comparator can response fast to the input signals. After accessing acceptable simulation results from designed comparator, the layout of each comparator components such as Op-amps, switches, and latch have been drawn and tested in Cadence Spectre Circuit Simulator.

The paper is aimed to analyse application of learning analytics (LA) methods to enhance learning quality and effectiveness in virtual learning environments (VLEs) by the means of learning personalisation. Since study and learning processes significantly moved to virtual environment, it is very important to analyse what is state-of-the-art in the area. Therefore, first of all, systematic review has been performed. The data collected from VLEs can be aggregated over large numbers of students and can contain many variables that LA / educational data mining (EDM) algorithms can explore for model building. Research presented in the paper has also shown that these LA methods and techniques could be successfully used to enhance learning quality and effectiveness by the means of learning personalisation in VLEs. In the paper, five-stage methodology is presented aimed at enhancing students' learning quality and effectiveness.
