Application of 3D measuring techniqes provides great benefits in field of product control. A three-dimensional scanning device is used in many applications in order to collect as much data as possible about product's shape, color and texture, etc. Acquired data can then be used for the construction of digital, three-dimensional models, as well ai in product development. The goal of this research is to obtain a computer-compatible digital object, in order to compare the data gathered by tree-dimensional scanning device with the existing previously created CAD model.

Lateral Chromatic Aberration is a defect of optical lenses in connection with focusing different wavelengths of light (red, blue, green) at different locations in the focal plane, which leads to resolution loss and color artifacts (fringes). To preserve image fidelity, we have developed a robust multi-phase unsupervised method (not using a reference image for calibration and without prior knowledge of the lens), that is based on edge matching in different color planes. We are able to estimate parameters of a lateral chromatic aberration correction model, which is then used to avoid these artefacts by correct resampling of red and blue color planes with sub-pixel accuracy. This method is suitable for real-time implementation in consumer-grade image/video systems and shows very promising results.

System components requirements definition for any long range multisensor imaging systems is important and rather complex task. In order to define those requirements for a system with as high as possible values of detection, recognition and identification, there are lot of compromises that need to take place, and simplified model is of great help for that process. A common detection, recognition and identification ranges prediction is shown, following with an architecture of long range multisensor imaging systems. Imaging channels key performance parameters are presented and put into relation with expected performance. The use of this model can have an important role in system components requirements definition, and model can be further extended for other classes of multisensor imaging systems.

This paper combines available NLP technologies for Serbian languages and traditional data science methods in order to analyze collected dataset on the news headlines related to the COVID-19 pandemics. As an addition to NLP technologies for the Serbian language, a specialized database was created in an attempt to enhance the research within the field. Within the paper, the database was exploratory analyzed, and perspectives of the work with the data were thoroughly explored.

Important component of any aerial bomb is the fuze itself. The fuze vAF-M17 is developed according to the military standards and as such has to meet all the safety features. Events which can occur on a functional fuze during its transport to any other location are unknown which lead to a development of in field testing software for the fuze. The following software is used to check for any irregularities in the fuze and to inform the operator of its functionality status.

The paper presents the realization of an experimental setup used for testing energy harvesting and storage devices based on the use of lead-free bismuth sodium titanate-barium titanate (NBT-BT) in combination with polyvinylidene fluoride (PVDF) polymer. PVDF is a polymer matrix in which piezoelectric phase is dispersed and enables formation of flexible films by hot pressing method. The paper presents an electromechanical model of a typical PVDF module, generates a simulation model, and presents simulation results. The experimental setup is based on a mechanical excitation for generating pulses of an force of different amplitude and duration, applied on the aforementioned energy harvesting NBT-BT-PVDF devices, likewise, on an electronic assembly for measuring the pulses of electrical quantities (current and voltage), that are generated at the output electrodes. The research in this paper is predominantly experimental and it shows the obtained oscilloscope recordings of the excitation force and output voltage of energy harvesting modules at different modes and conditions of mechanical excitation. After this, a comparison of the simulation and experimental results is made.

The paper deals with comparative laboratory tests of operating characteristics of the early streamer emission (ESE) lightning rod and Franklin rod. Laboratory tests are performed by using high direct test voltage, and lightning and switching impulse test voltages. Dependence of the amplitude and frequency of the ESE rod tip voltage on the value of applied high direct test voltage is presented. The upward currents and high frequency pulses at the tip of ESE and Franklin rods, caused by high direct test voltage, are measured. Comparisons of the ESE rod and Franklin rod efficiencies is performed by counting number of flashovers to the tip of each rod, caused by lightning and switching test impulse voltages. Good correlations between the results from different tests are estimated.

Decarbonization of power systems represents the main tool of energy transition and sustainable development. Faced with many challenges, decarbonization of power systems needs the application of new technologies for production and energy storage, advanced optimization algorithms and artificial intelligence algorithms for system operation and control, as well as the utilization of all available balancing resources, especially at the distribution level by activating consumers and distributed resources. This paper gives an overview of the current state of decarbonization process in the world, including CO2 emission, electricity consumption rise, the rapid growth of electric vehicle sales and changes in power systems needed for their utilization.

In research to determine the degree of interest in enrolling students in certain high schools, predictive analysis and comparison models are rarely used when classifying and processing different data. All this leads to large fluctuations in enrolment in secondary schools, where certain schools are unable to enrol numerous students who show an interest in a particular field. On the other hand, students lose interest in certain schools, which leads to the discontinuation of certain courses necessary for the needs of today's labour market. Institutions responsible for organizing the educational process do not sufficiently compare and connect teaching and non-teaching activities when analysing the talents and interests of elementary school students from different fields. The goal of this work is to predict the enrolment of students in secondary schools, using the classifiers of programming languages, based on the results that students express during regular classes in elementary schools.The results show that the accuracy of the data during the training of the Random Forest predictor is 52%, while in Wolfram Alpha it is 62%
