This article presents the original method of tomographic investigation of rising damp in walls made of ceramic (clay) bricks based on artificial neural networks. A model consisting of multiple neural networks was developed in such a way that a single network generates a single pixel image. The results of simulation experiments confirmed the high efficiency of the presented method.

In industry 4.0, modern and automated production processes based on sensor networks are becoming more and more complex, and companies expect high-quality products at optimal costs. Therefore, process optimization is becoming increasingly important. The article presents a sensor-based measuring system based on electrical capacitive tomography for optimization and production quality control. This paper provides the prototype of electrical capacitance tomography system with applied algorithm modifications for faster performance.

This paper describes a process of developing procedures of investigating and determining origins of a vehicle, based on its digital identification data stored in electronic control units as the Vehicle Identification Number. The 17-digits standardized VIN number uniquely identifies every modern manufactured car and is placed in a visible way in several different places including car chassis, car body and documentation. Additionally, depending on a manufacturer, VIN is located in numerous electronic control units (ECUs) in non-volatile EEPROM memories. Despite being prohibited by law there has been rapid growth of unauthorized VIN changes over the last decades caused by unrestricted access to high-tech chip tunning tools developed primarily for engine performance improvements. This approach has become widely exploited by cars thieves to mask original identity and resell stolen cars and parts on 2nd hand markets, glossing over their history. The aim of the research is to collect information on types of memories installed in ECUs, available security mechanisms protecting their data, storing patterns as well as describe attempts to determine a vehicle depending on the structure of the VIN read from the ECU including all types of information encoded. Results and conclusions were obtained based on several available Bosch Electronic Diesel Control units.

The article analyses the lateral-torsional buckling of a double symmetric, steel I-beam with an assumption of a non-fork support. The fork support assumes free lateral bending and free warping what is described by factors kz and kw. In the Eurocode 3 there is no solution concerning how to calculate the value of a critical moment for steel structures. Information about it can be found in the pre-code for European Standard 3, the German Standard and scientific papers. In the calculations assumed the loads generating a non-uniform shape of bending moment diagram what is connected with a value of C1 factor. Calculations were conducted using equations derived by Lindner, Lopez and others and the applications such as LTBeamN and ABAQUS which allows to use a scheme with 7 degrees of freedom in boundary conditions. The non-fork support is created by adding endplates which reduce the possibility of warping by blocking the rotation between the flanges. A stiffness of endplates was calculated using the Saint-Venant's formula and was incremented into the equations and LTBeamN. In ABAQUS the I-beam was modelled as a shell structure with endplates discretized with a mesh of solid elements. The type of Finite Elements was chosen in accordance to previous research, where an influence of a mesh scheme on result was taken under consideration. To check the lateral-torsional buckling in ABAQUS a “buckle” analysis was conducted.

Non-destructive methods like EIT tomography can be used to search for the distribution of wall dampness. From a practical point of view the boundary is searched between wall areas considered as dry and damp. For the forward problem solution the boundary element method will be applied. This allows us to use either the multilayer model or a model implementing functionally graded materials. Within the inverse problem solution coefficients for the height and shape of the boundary between the damp and dry model, or distribution coefficients of functional material properties will be searched.

This paper deals with the problem of controlling the water flow in such a way as to enable it to be sterilized using a lamp emitting ultraviolet radiation. The controller's task was to adjust the opening of the valve regulating the liquid flow rate depending on the degree of turbidity and the age of UV-C lamp. The control algorithm uses artificial neural networks.

Optical Character Recognition (OCR) applications usually require the use of uniformly illuminated images which can be obtained using the flatbed scanners. However, rapid development of mobile technologies causes the growing popularity of document images captured by built-in cameras being the integral parts of modern mobile phones and tablets. Many companies and administration offices accept not only the scanned documents but also high resolution photos which can be enough e.g. for insurance purposes. Unfortunately such images can be unevenly illuminated causing some problems for the OCR applications used for text recognition especially if the QR, Aztec or some other popular 2D codes are not present. Proper text recognition from camera images requires image preprocessing including its binarization which cannot be conducted using typical global thresholding due to the presence of local intensity changes. On the other hand the use of pixel-based adaptive methods is time-consuming and not always leads to satisfactory results. To fill this gap and balance the recognition accuracy and high processing speed a region based approach to image binarization is proposed in this paper being an extension of well-known Niblack thresholding algorithm.

How the increase in number of approximation nodes improves the identification of the parameters of transfer function in transfer function models of electromagnetic field diffusion. Based on the frequency response determined for magnetic induction the authors calculated the normalized moments followed by the parameters of chosen transfer function models. To calculate the moments, the authors increased the number of pulsations, which in succession lead to increase of the computation difficulty and required time, but also improved the alignment of model dynamics to real-time object dynamics. The authors show on an example that to some extent increasing the pulsation number improves the transfer function models.
