A Novel Fast Feedforward Neural Networks Training Algorithm
Authors: Bilski Jarosław , Kowalczyk Bartosz , Marjański Andrzej , Gandor Michał , Zurada Jacek 
Published: October 2021

Abstract
In this paper1 a new neural networks training algorithm is presented. The algorithm originates from the Recursive Least Squares (RLS) method commonly used in adaptive filtering. It uses the QR decomposition in conjunction with the Givens rotations for solving a normal equation - resulting from minimization of the loss function. An important parameter in neural networks is training time. Many commonly used algorithms require a big number of iterations in order to achieve a satisfactory outcome while other algorithms are effective only for small neural networks. The proposed solution is characterized by a very short convergence time compared to the well-known backpropagation method and its variants. The paper contains a complete mathematical derivation of the proposed algorithm. There are presented extensive simulation results using various benchmarks including function approximation, classification, encoder, and parity problems. Obtained results show the advantages of the featured algorithm which outperforms commonly used recent state-of-the-art neural networks training algorithms, including the Adam optimizer and the Nesterov’s accelerated gradient.

Published: October 2021

Abstract
The paper presents a performance analysis of a selected few rough set–based classification systems. They are hybrid solutions designed to process information with missing values. Rough set-–based classification systems combine various classification methods, such as support vector machines, k–nearest neighbour, fuzzy systems, and neural networks with the rough set theory. When all input values take the form of real numbers, and they are available, the structure of the classifier returns to a non–rough set version. The performance of the four systems has been analysed based on the classification results obtained for benchmark databases downloaded from the machine learning repository of the University of California at Irvine.
Performance Analysis of Data Fusion Methods Applied to Epileptic Seizure Recognition
Authors: Ludwig Simone A. 
Published: October 2021

Abstract
Epilepsy is a chronic neurological disorder that is caused by unprovoked recurrent seizures. The most commonly used tool for the diagnosis of epilepsy is the electroencephalogram (EEG) whereby the electrical activity of the brain is measured. In order to prevent potential risks, the patients have to be monitored as to detect an epileptic episode early on and to provide prevention measures. Many different research studies have used a combination of time and frequency features for the automatic recognition of epileptic seizures. In this paper, two fusion methods are compared. The first is based on an ensemble method and the second uses the Choquet fuzzy integral method. In particular, three different machine learning approaches namely RNN, ML and DNN are used as inputs for the ensemble method and the Choquet fuzzy integral fusion method. Evaluation measures such as confusion matrix, AUC and accuracy are compared as well as MSE and RMSE are provided. The results show that the Choquet fuzzy integral fusion method outperforms the ensemble method as well as other state-of-the-art classification methods.
Modelling of Drag Force Reduction for a Waterjet Propulsion System
Authors: Cerpinska M. , Irbe M. , Pupurs A. , Burbeckis K. 
Published: October 2021

Abstract
The paper provides simulation results for SUP (Stand Up Paddle) board appendage resistance. Additional propulsion is added to the SUP board. It is equipped with a waterjet. The waterjet is attached to the board rudder. This increases the drag coefficient for rudder five times. To reduce the drag variable, design options for the waterjet duct were proposed. The simulation tests were performed using SolidWorks Flow software using two types of simulations, namely, the pressure on the body and the flow around the body. The objective was to streamline the bluff duct of the waterjet and thus to create the appendage design with minimum drag force from fluid flow and possibly greater Inlet Velocity Ratio. Calculations showed that rounding-off the edges of waterjet duct resulted in 35 % of drag coefficient reduction, while further streamlining reduced it by additional 10 %.

Authors: Gerbreders V. , Krasovska M. , Mihailova I. , Kostjukevics J. , Sledevskis E. , Ogurcovs A. , Gerbreders A. , Bulanovs A. 
Published: October 2021

Abstract
To increase the sensitivity and efficiency of a gas sensor, nanostructured ZnO and Co3O4 layers were obtained by hydrothermal synthesis directly on the electrode surface, eliminating the use of binders. Scanning electron microscope images showed that the resulting nanostructured coatings were characterised by good adhesion to the surface and high porosity, which opened up the possibility of their further use in the process of developing a gas sensor. The efficiency of the obtained nanostructured coatings and their sensitivity at room temperature to various concentrations of CO2 were determined. The resistance curves of the samples were obtained as a function of gas concentration in the chamber, for Co3O4 and ZnO nanostructures.

Published: October 2021

Abstract
The study offers a new method of collection and processing of meteorological data from the meteorological service based on observations and correction of numerical weather forecast errors using a new prediction algorithm. This algorithm vastly increases the accuracy of the short-term forecast of outdoor air temperature, which is subject to uncertainty due to the stochastic nature of atmospheric processes. Processing of temperature data using Kalman filter provides the decrease in predicted temperature errors. The main setup methods of Kalman filter have been examined. The article also describes the implementation of accuracy improving algorithm of predicted temperature using Python.

Published: October 2021

Abstract
Historical maps are a valuable resource in landscape research. The information gathered from them facilitates the cognisance of landscapes and may assist current landscape planning. This study focuses on the historical occurrence and spatial extent of man-made ponds in the Czech Republic. Based on the 1st Military Survey maps (1764–1783) of the Habsburg Monarchy, we use Historical GIS to identify 7,676 man-made ponds in the historical landscape. Compared to the 2nd Military Survey maps (1836–1852), 56% of these man-made ponds had been drained. Such disappearances mostly affected large ponds in fertile agricultural areas, but also affected small reservoirs in less fertile areas at higher altitudes. As the current maps and spatial datasets (Water reservoirs, Landscape water regime, Farming areas) show, a number of these agricultural regions have been affected by climate changes and face water shortages. The historical map information of former ponds has the potential to contribute to their restoration in areas where water retention in the landscape needs to be increased.
From the agricultural station to a luxury village? Changing and ambiguous everyday practices in the suburb of Vinnytsia (Ukraine)

Published: October 2021

Abstract
The study of everyday practices, self-identities and perceptions seems to be a promising approach to understand the suburban spaces as not only static containers but socially constructed, dynamic and ambiguous entities. Our case study is represented by the suburban village of Ahronomichne, located in the peri-urban area of the second-order Ukrainian city of Vinnytsia. The research methods included survey of residents (67 long-term residents and 59 newcomers), observations of the everyday activities of the residents and appearance of the build environment at seven observation points within the village, and four semi-structured in-depth interviews. We found that everyday practices of the long-term residents and newcomers significantly differ in terms of their set, spatial configuration and actual exercitation. The other important factors contributing to the variety of everyday practices and lifestyles are type of housing, age and family status. Simultaneously, we observed not just a combination but rather intertwining, mixing and hybridisation of urban, suburban and rural everyday practices and lifestyles. Another finding of the research was the western-type suburban growth of the second-order Ukrainian city in contrast to the largest cities of the country where centrifugal migrations of rich people to peri-urban area combines with the centripetal stream of less affluent migrant from peripheral settlements, keeping transitory residential strategy.
How are allotment gardens managed? A comparative study of usage and development in contemporary urban space in Germany and Poland

Published: October 2021

Abstract
This article aims to analyse the development and use of allotment gardens (AGs) and plots in Westphalia and Lippe (Germany) and Wielkopolska (Poland) to assess what functions are feasible in their current stage, thus, contributing to an ongoing discussion on the role of AGs in contemporary urban space. The analysis considered ecosystem services, green infrastructure and urban agriculture. Characteristic features of AGs were identified by means of a survey of plot-holders, in-depth interviews with representatives of allotment associations, and exploratory walks. The management and use of AGs differs in both regions in terms of accessibility, common areas, impact on the landscape and plots development. AGs in Westphalia and Lippe are accessible and developed in a way which meets needs of external users. They fit harmoniously into the surrounding landscape. However, AGs in Wielkopolska are not as accessible, prioritise internal users, and do not always blend in with their surroundings. In Westphalia and Lippe, in addition to recreational and edible plant-growing plots, there are also educational and integration ones, while in Wielkopolska main categories of plots were more numerous and varied; from recreational with a predominance of ornamental plants to fully-cultivated. However, the considerable freedom that Polish plot-holders enjoy gives rise to the gradual marginalisation of edible-plant growing.

Published: October 2021

Abstract
The scheme of arrangement of grooves of partially regular microrelief of type II shifted by 0.5 angular pitch is considered. Such grooves are formed by vibration on end faces of rotary bodies. An analytical dependence was obtained to determine the relative area of a partially regular microrelief depending on the geometric parameters of V-shaped grooves. The parameters of the grooves of a partially regular microrelief formed at different distances from the center of rotation are determined, at which the value of the relative area of the partially regular microrelief formed on the treated surface will be stable.

Published: October 2021

Abstract
The recuperative heat exchangers are an important part of the industrial plants. There are a number of such heat exchangers that differ in the arrangement of the streams. The knowledge of the flow arrangement of the streams is very important from a point of view of the heat exchangers calculations. There are various calculation methods, but only one takes into account the flow arrangement of the streams directly. The quantity that takes this into account is called the countercurrent index. The article deals with the determination of this quantity for a given recuperative heat exchanger.
Modelling Pedestrian Crossing Behaviour at a Midblock Section
Authors: Poojari Yugendar , Prashanth E. , Divya D. , Kalyani M. 
Published: October 2021

Abstract
In general, pedestrians want to cross a road at a mid-block section instead of intersections because it is the shortest route. According to an Indian scenario, most of the crosswalks in urban areas are not signalised and controlled. In this study, the crossing behaviour of pedestrians in terms of speed at a midblock section was studied by considering several parameters. Statistical tests such as ANOVA and Pearson correlation tests were performed in order to know the effect of parameters on the crossing speed of a pedestrian. The pedestrian’s age and gender, crossing type, pattern, time, number of stops, number of two wheelers, three wheelers, light and heavy commercial vehicles, and groups significantly affect their crossing speed. A multiple linear regression model was developed by considering the most significant parameters. The mean absolute percentage error, root mean square error, and R2 values were calculated to validate the models.
Measuring Control Delays at Signalized Intersections in Mixed Traffic Conditions
Authors: Sushmitha R. , Ravishankar K. V. R. 
Published: October 2021

Abstract
Control delay is the key performance indicator of a signalized intersection that defines the level of service. Several models have been developed in previous research work for estimating control delays, but many of them were based on homogeneous traffic conditions. In the present study, an Open Street Map (OSM) tracker mobile application was used to measure control delays from the field. A non-linear model was developed in the present study for estimating control delays in mixed traffic conditions using a MATLAB fitting tool. The field delay is compared with the developed non-linear model delay along with the Indian Highway Capacity manual (INDO HCM) and Highway Capacity Manual (HCM) models. The control delay estimated using the model developed in the present study shows a close relation with the field delay obtained using an OSM tracker when compared to that obtained using the INDO HCM and HCM models. Therefore, the OSM tracker mobile application can be used as a field control delay measuring technique.

Authors: Bućan Nikolina 
Published: October 2021

Biblioteka PyGame se razvija još od ranih 2000. godina. Sami autori kažu da nije u pitanju najbolja biblioteka za programiranje igara, ali glavna prednost joj je to što je jednostavnija od drugih za korišćenje i pogodna je za učenje programiranja kroz interesantan svet računarske grafike i računarskih igara, koje danas igraju značajnu ulogu u životima pojedinaca, ali i celokupnog društva. Istorija video igara seže do 1948. godine kada je Tomas T. Goldsmit (Thomas T. Goldsmith) dobio ideju video igre i patentirao je. Može se reći da je od tada industrija video igara u konstantnom usponu i napretku. Video igre su namenjene uranjanju igrača u neku vrstu virtuelne stvarnosti. To se postiže pre svega vizuelno, ali može napraviti ogromnu razliku i biti veliko poboljšanje igre ako vizuelni deo prate adekvatni audio zapisi.
