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.

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.

Digital agriculture is seen as a potential solution for improving sustainability of agri-food systems, increasing the productivity, efficiency, while decreasing costs of production and negative impact on environment. Majority of developed countries have made significant efforts in digital transformation of agricultural sector to leverage the benefits of digital agriculture. However, developing countries are still lagging and have only made modest steps in this direction. This paper gives an insight into some elements of digitalization of agriculture in Bosnia and Herzegovina, with focus on several digital solutions developed for small farmers. Although these small-scale solutions are developed with very limited resources, they are successfully used by small farmers to solve their real-world problems.

This paper presents design, production, testing and biomedical application of an interdigital capacitor made exclusively from edible materials (food). The purpose of this work is to demonstrate suitability of the sensor made from edible materials to detect pathological condition in the oral cavity. Interdigital capacitors were made on edible substrates such as biscuits, edible wax, and buckwheat tiles, while aluminum foil was used to make the conductive segments. The tests were performed at room temperature with the HIOKI IM3590 impedance analyzer device.

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.
