<strong>Purpose.</strong> Recently, the demand for reuse of industrial buildings that have not been in operation for some time has been increasing in Ukraine. Herewith, quite often the design of their roof requires the complete replacement and renovation by using modern roofing materials to meet the requirements of new government standards. Therefore, the choice and justification of the rational design of steel roof on the example of a short-span industrial building (18-24 m span), which is planned to be returned to exploitation after idle time, is the main goal of this publication. The object of the analysis is an unheated building equipped with bridge cranes of a small capacity (up to 10 tons). <strong>Me</strong><strong>-thodology.</strong> To achieve this purpose, the comparison of structural variants of a roof steel collar tie was performed. Such variants include two types of collar tie cross-section –a lattice truss and a solid I-girder. The first type was analyzed for four possible types of section of elements – double angles, a roll-welded square profile, an electric-welded round tube and a rolled round tube. The second type was analyzed for two possible types of section – rolled I-section made of normal strength steel and fabricated sections of thin-gage high-strength steel. The design variants were compared on the basis of a numerical analysis of their work using the finite element method based on the software complex SCAD for Windows.<strong> Findings.</strong> According to the research results it should be stated that for the conditions of the city of Dnipro the most cost-effective variant of the steel collar tie cross section for the short-span industrial building is the truss made of electric-welded round tubes. Also the construction of collar tie made of roll-welded square profiles or fabricated section of thin-gage high-strength steel is considered quite effective. <strong>Originality.</strong><strong> </strong>The research presented in the publication allows estimating the possibility and economic efficiency of usage for various types of cross-sections for the collar tie of a steel non-insulated roof of the industrial building for the reconstruction conditions in the Dnipro-city. <strong>Practical value.</strong> A practical estimation of mass and cost parameters for steel collar ties of various types has been carried out, and the methodology for conducting such estimation has been substantiated.

"Influence of orthopedic shoes on the indicators of the interzonal load distribution on the foot when walking patients with cerebral palsy." Pediatric Traumatology, Orthopaedics and Reconstructive Surgery 9, no. 1 (2021): 51–61. http://dx.doi.org/10.17816/ptors41766.

BACKGROUND: Clinical observations of patients with spastic forms of cerebral palsy and surveys showed the most commonly used technical rehabilitative device of this patient contingent are orthopedic shoes. However, almost no clinical and instrumental studies examine the effect of such shoes on the walking characteristics of patients with cerebral palsy (CP).
 AIM: This study aims to estimate the effect of orthopedic shoes on the interzonal load distribution on the plantar foot surface in children with CP and adolescents with different levels of gross motor function disorders (GMFCS).
 MATERIALS AND METHODS: Biomechanical studies were conducted in 42 patients with CP 5-16 years old with GMFCS 13 level while wearing standard and orthopedic shoes. In 14 healthy children controls while wearing standard shoes (a total of 112 feet). Biomechanical examinations were performed on the software and hardware complex DiaSled-M-Scan with matrix plantar pressure meters in the form of insoles. Statistical data analysis was performed using nonparametric methods via SPSS software for Windows.
 RESULTS: The use of complex orthopedic shoes in patients with level GMFCS 1 did not improve but worsened their foot loading parameters. The shoes reduced the loading of the heel, increased the toe-heel load ratio, and mediolateral load distribution in the fascicle area. In patients with GMFCS 2, the positive effect of orthopedic shoes was limited to improving the mediolateral load distribution in the fascicle area. In patients with GMFCS 3, the positive effect of orthopedic shoes was noted in the majority of the tested parameters.
 CONCLUSION: Thus, the study showed that in children and adolescents with CP using complex orthopedic shoes led to the most significant normalization of interzonal load distribution under the foot in GMFCS 3 patients, less significant in GMFCS 2 patients, and worsened the parameters in GMFCS 1 patients.

Full textAbstract:
Stuxnet is a highly customized malware developed to destroy centrifuges used in the Iranian nuclear program through SCADA systems. It infects a computer through a USB drive, making it effective for targeting air-gapped networks. Stuxnet is larger and more complex than an equivalent worm; it is created in several different programming languages, and some components are encrypted. The malware utilizes four unprecedented zero-day vulnerability attacks that exploit application security vulnerabilities before developers become aware of the vulnerability. Additionally, it employs advanced rootkit technology to conceal itself from users and antimalware software on both Windows and the control computer it targets. To strengthen cybersecurity, this study implemented and configured a combination of firewalls and intrusion detection systems (IDS) to enhance security against the Stuxnet malware. By integrating these security measures, the aim was to establish a robust defense against the sophisticated attack methods employed by Stuxnet. It is essential to continuously update and adapt these security measures as the threat landscape evolves. By remaining vigilant and proactive, organizations can effectively safeguard their systems from sophisticated threats like Stuxnet, bolstering their cybersecurity defenses.

Abstract Background: Automated laboratory analyzers that mass produce data have been linked to information systems for more than two decades, but little progress has been made in developing more comprehensible report forms. Results are still reported in computer-generated printouts containing hundreds of numbers crowded into columns on each printed page. Methods: We developed three software applications focusing on the graphic presentation of laboratory results. Results: The first application summarizes data for a patient with a monoclonal gammopathy. The report provides a cumulative graphic presentation of immunofixation/electrophoresis data without any additional interpretation, focuses on a color-coded electrophoresis scan, and records up to 5 years on a single page. The second application deals with cerebrospinal fluid analysis. The report calculates relevant data and graphs the complex relationship between albumin and immunoglobulin results from paired serum and cerebrospinal fluid samples. Manually added interpretive text assures an output comprehensible to clinicians in all specialties. The third application produces a report summarizing quantitatively measured urinary marker protein profiles. The report form is generated by a flexible, completely user-definable knowledge-based system. It calculates numerous ratios and formulae, supports reflex testing, supplies an automated interpretation, and generates a specific graphic signature pattern of the results (MDI LabLink proteinuria differentiation). Conclusions: Increased clinical demand for graphically oriented report forms 5 years after their introduction has provided evidence that these reports transfer complex laboratory data and results to the clinician more effectively. The highest (more than threefold) increase in demand has been for reports for urinary marker protein profiles that feature a largely self-explanatory graphic signature pattern.

The paper highlights combined techniques of strengthening that include geotextile laying as well as other related advanced technologies. Subgrade construction analysis and its modification, reinforced with the different types and options of combined strengthening were conducted. To justify strengthening of subgrade a series of numerical calculations were made. Simulation with software package SCAD has confirmed the experimental results. From obtained results one can conclude that minimum horizontal displacements are observed in the version with deepening of geotextile at 1m and vertical ones at 0.4 m. Based on simulation results it is possible to make recommendations concerning modernization of existing subgrade and construction of new one in complex engineering-geological conditions

This article is devoted to the analysis of one of the most common structural designs of the steel frame of small spans, currently used in India in construction and reconstruction for seismic areas. This scheme constructively involves the implementation of the main bearing elements - bolts and columns - in the form of a spatial truss box section. At the same time, rather simple rolling profiles from small-sized corners are used, as well as a round steel bar. The studies performed by the authors were carried out using the finite element method based on the national design computing complex SCAD for Windows. The loads, as well as the geometrical characteristics of the profiles, were taken according to the current building standards of India. Based on the results of the analysis, a number of recommendations were formulated to improve the efficiency of the considered design scheme for seismic effects of varying intensity.

Today the use of software has developed in various fields of human life, including the world of education. These developments also have an impact on learning mathematics in general and linear programming as part of mathematics. The software on the computer that is used to solve problems in linear programming material is POM-QM FOR WINDOWS. POM-QM for Windows is a software that can be used to solve various problems related to linear programming material, ranging from very simple problems to more complex problems that are difficult to solve manually. With this software, it is hoped that it can facilitate the process of learning linear program material carried out by teachers in schools. To be able to solve these linear programming problems both manually and by using the POM-QM for Windows software, then of course these problems must be made/formulated in the form of a mathematical model through the model formulation process or what is commonly known as modeling. Modeling is the process of translating real/everyday problems (linear programming problems) into mathematical language (abstract problems).

Introduction. Current requirements for structural engineering oblige designers to use structures capable of resisting progressive collapse. Such structures include multiribbed reinforced concrete waffle slabs. Spatial systems are multiple indeterminate, their calculation is carried out in software systems based on the finite element method. Models of ribbed structures can be developed from different types of finite elements. The forces determined by different models can vary significantly, which is confirmed by the examples available in the literature.Aim. To detect a simple and accurate finite element model for computer-aided calculating the ribbed reinforced concrete waffle slab.Materials and methods. The study was carried out by comparing the bending moments obtained analytically and in the SCAD software by the finite element method for beams in waffle slabs of 12.0 × 18.0 m in plan with caissons of 1.5 × 2.25 m. The bar model consisting of a T-beam-and-girder construction and a solid model of bulk finite elements are calculated.Results. The bending moments, calculated both analytically and using a solid model, have similar values. The maximum deviations of the computer calculation from the analytical method are from -3.2 to +2.6 %. The maximum deviations of the values of bending moments obtained when comparing the solid model with the bar model are from -9.2 to +4.0 %.Conclusion. The finite element model, which is based on solving the volumetric problem of the elastic theory, is an effective verification model for studying complex systems; however, it is time-consuming and difficult for data analysis. A solid model can be recommended for studying individual structures or their critical zones.

Over the past ten years, the U.S. Army Research Laboratory (ARL) Human Research and Engineering Directorate (HRED) has developed tools and techniques to support Manpower and Personnel Integration (MANPRINT). Most notably, a set of tools was developed in the DOS environment that has become known as the Hardware vs. Manpower (HARDMAN) III tools. These software tools provide an analytical basis to address the ways in which the Army's manpower, personnel, and training elements are affected by a new system. During the last two years, ARL HRED has begun an effort to improve the capabilities of this tool set by moving them into the MicroSoft Windows™ environment. This paper describes the process through which this complex DOS tool set was redesigned to provide a better functional capability as well as to take advantage of the graphical user interface provided by this environment.

The article deals with the natural conditions of the karst, the factors of its development and the impact of this geological process on the stress-strain state of the building frame. In the software complex SCAD developed 10 versions of models of frame-monolithic multi-storey building, taking into account the variation of karst localization. Taking into account the influence of karst processes on the stress-strain state of the frame of the building allowed to calculate the movement of the base plate, depending on the location of the funnel, to identify the greatest movement and choose the reinforcement that provides the necessary strength of the frame of the building in any adverse karst process.

The purpose of the work is to evaluate the spatial distribution of the rigidity of the carrier frame and the body of the Ukrainian electric locomotive DC3 as a single system during operation and repair. The research was carried out on the basis of the finite element method with the application of design and computing complex SCAD for Windows. The numerical model of the electric locomotive was built, tested and then used to identify the causes and providing guidance on solving some specific operational questions. They are included, for example, the possibility of eliminating the body skew when jacking up on jacks and jamming the door as a result. The researches showed that the structure of the electric locomotive DS3 in general has a rather high spatial rigidity, both in transverse and longitudinal directions, and on torsion. However, for some practical repair tasks there is not enough for that rigidity. It was recommended to increase the thickness of the shell of its body up to 4 mm or the roof up to 8 mm, which leads to an increasing in the total mass of the machine by about 2,5 and 3,5 tons, respectively.

The present work is aimed at studying the design of shallow foundations for overhead power line the towers under complex engineering and geological conditions. The study investigates existing designs and reveals their main shortcomings. In order to increase structural stability in complex soil conditions, the experience of constructing overhead power line towers using a shallow foundation is considered. The proposed shallow foundation option demonstrates increased strength and structural reliability. The shallow foundation design was carried out using the SCAD design software analysing the finite element model of static and dynamic loaded computation schemes, monitoring the structures for stability, checking metal systems for reliability and selecting disadvantageous combinations of forcing. The finite element method on which the software is based uses the movements and rotations of the structural nodes in the computation scheme as the main unknown variables. Two shallow foundation options are considered under equally complex soil conditions with the same loads, but a different arrangement of collar beams. Under complex engineering and geological conditions and the action of maximum loads, the calculation showed the greatest difference in the foundation settlement between the two options to increase by 2 times. The significance of the difficulties involved in increasing security of supply established by the development strategies of the electric power industry in Russia is presented. A design models for towers having shallow foundations, operated as beams of complex geometry, was selected. Experimental and analytical studies demonstrated the practical effectiveness of using the identified shallow foundation approach.

This paper presents the research results of applying the combined method of probabilistic statistical approaches, energy density spectral correlation, two-dimensional filtering in dynamic sliding windows, full horizontal gradient and heterogeneous axis tracking method to process and interpret the Bughe gravitational anomaly field in central area Vietnam. The calculation results have shown the superiority of the twodimensional filter in dynamic sliding windows compared to the filters in fixed windows in GEOSOFT software, GMT software. According to the physical characteristics of the field, the study area was divided into 13 homogeneous classes, this result is consistent with the geological-tectonic data in the area. In the north and northeast, the stabilized rock layers are characterized by homogeneous layers that extend in the northwestsoutheast direction. In the south and southwest, there is complex tectonic activity characterized by high density rock layers overlain by low density rock layers in each fault band with different directions of development. This suggests that there may be deeply buried mineral deposits of magmatic origin in central area Vietnam.

The rapid advancement of network, communication and Internet technology resulted with always-on, always-connected, device-independent and remote online working, business, education and entertainment environment. Consequently, users are searching for solutions and technologies that enable fast and reliable wide area network connection and the typical solution is through using personal computers connected with ethernet cable to network equipment and infrastructure that supports gigabit ethernet connection. Besides the complex network infrastructure that can influence performance, the bottleneck can also be caused by insufficient hardware, operating system and software resources on clients’ machines. Therefore, in this paper a networking performance evaluation of three globally most common and most used versions of Windows operating systems; namely Windows 7TM, Windows 8.1TM and Windows 10TM, on two identical computer systems, is conducted. Networking performance measurements are performed with three different benchmarks: namely iPerf, D-ITG and NetStress. Performance evaluation results showed that a newer versions of an operating system bring certain networking performance improvements but by sacrificing other performances.

Increasing the height of buildings and structures in combination with the development of areas with unfavorable geotechnical conditions cause the use of foundations in the form of solid reinforced concrete slabs. In complex geotechnical conditions and under high loads, the soils can work beyond linear deformation. This necessitates the calculation of the system "building-foundation-soil" based on the assumptions of nonlinear soil mechanics. The issue of designing foundations for cylindrical structures of the agro-industrial complex, in particular granaries, is especially relevant. The task of this study is a comparative analysis of different methods for calculating the subsidence of slab foundations to select a rational model of deformation of the soil. The comparison of calculation methods is carried out on the example of the foundation under the granary with a volume of 8841 m3. The foundation is made in the form of a round reinforced concrete slab with a diameter of 20.4 m. The characteristics of the soil are established by the results of geotechnical surveys. The calculation according to the Winkler model (elastic base plate with one coefficient of subgrade reaction) was performed in the "Cross" module of the SCAD Office software package. With a total load on the foundation of 2741 tf, its average subsidence is 2.15 cm. The calculation according to the model of three-dimensional finite elements of cubic shape was performed in the environment of the SCAD Office software package. The average subsidence of the foundation is 2.4 cm. The calculation by the method of layer-by-layer summation according to the instructions of DBN B.2.1-10: 2018 gave the subsidence of the foundation slab equal to 13.7 cm. The actual average subsidence of the foundation during the observation period in different areas of the foundation was 1.1… 2.4 cm and averaged 1.75 cm. The comparison of the analyzed methods for determining the subsidence of the foundation indicates the closeness of the results of calculations on the model of the slab on an elastic basis and the model of three-dimensional finite elements to the actual value of subsidence and the greatly higher result of the calculation by layer summation. The use of the latter method leads to excessive reliability in the design of foundations.

The article discusses the methodology and design template for a complex of structurally, functionally, informationally and metrologically compatible software modules that implement algorithms for calculating estimates of the PSD power spectral density based on binary-signed analog-stochastic quantization with reduced multiplicative complexity. Algorithmic support makes it possible to calculate PSD estimates by the method of averaged modified periodograms and by the correlogram method using time correlation windows based on a discrete-event representation of the results of binary-sign analog-stochastic quantization. This approach made it possible to perform integration operations analytically, which eliminates the methodological error caused by performing these operations in digital form. In addition, the multiplication operations degenerate into procedures that basically require the execution of logical operations and simple arithmetic operations of summing and subtracting the values of the correlation windows, which significantly reduces the complexity of estimating the PSD.

Introduction. The article addresses the issue of designing complex architectural forms in modern sacred architecture, with a focus on structural feasibility and engineering analysis. It highlights the importance of building structures as a key factor enabling the implementation of unconventional spatial solutions within real-world construction conditions. The relevance of a comprehensive approach to form-making is emphasized — one that encompasses both the architectural concept and precise engineering analysis. Problem Statement. The lack of unified methodologies for modeling, analysis, and regulatory frameworks for the design of complex structural systems creates challenges in the practical realization of innovative architectural forms. This is particularly relevant in the field of sacred architecture, where visual expression must be structurally justified. Purpose of the Article. To outline the prospects of modern structural design of complex forms using examples from sacred architecture, and to substantiate the need for updated approaches to structural analysis, typology, and regulatory standards. Materials and Methods. The study employs the method of analyzing implemented architectural- structural solutions in sacred construction, tools for parametric and geometric modeling (Grasshopper, Rhino), software for FEM analysis (LIRA-SAPR, SCAD Office, Karamba3D), a review of current regulations, and comparative engineering calculations. The typology of modern structures and principles of their adaptation to complex forms are considered.

Failure distributions and reliability values for various components can be identified and stored in a database. Various components and sub-systems can be used to build series- parallel or complex systems. The components data can also be used to build fault trees. The software tool can compute reliability of complex state independent and state dependent systems. The tool can also be used to compute failure probability of the top node of a fault tree. The software was implemented in Visual Basic with SQL as the database. It operates on the Windows 7 platform.

The article provides an analysis of modern and affordable software systems for modelling shells of complex geometry and the possibilities of using these software systems in 3D printing. Such an analysis made it possible to choose software systems that most accurately allow for the implementation of the 3D modeling method proposed in the article with subsequent printing on a 3D printer. This method is considered in detail on the example of constructing several types of helicoids. The process of 3D modeling of a helicoid is described step by step and is divided into several stages: parametric modeling of a helicoid in SCAD, editing of the resulting model in AutoCAD and its export to a special format for 3D printing. The use of the method of parametric modeling is due to its accuracy and uncompromisingness. With its help, one can accurately judge the type of the built surface. Parametric modeling is the construction of a surface by compiling equations on each axis, i.e. along the x, y, z axes, and for each type of surface there are specific characteristic equations. It is not possible to implement the method of parametric modeling in all software systems; in this connection, certain difficulties arise. The article analyzes the difficulties encountered in 3D modeling of the helicoid and suggests ways to solve them.

The addition of new houses in the Kota Mas Cimahi housing complex has triggered an increase in the need for electricity distribution installations. To optimize the electricity distribution network, in this case minimizing the installation of electrical cables, an application is needed that can optimize the installation of electrical cables, namely the Kruskal algorithm which is an algorithm for finding the minimum spanning tree value on a weighted graph. In this study, two methods will be used, namely the manual method and the POM-QM for Windows software to help solve the minimum spanning tree problem. This study's goal is to identify the Kota Mas Cimahi housing complex's energy distribution network model's graph structure and determine a minimum spanning tree solution with POM-QM for Windows software and the Kruskal technique done by hand. In order to gather data for this study, PLN was the primary and secondary source Cimahi UP3. The distribution data for the electricity cable network is arranged in the form of a network image. By representing the electricity distribution network in the form of a graph, the minimum spanning tree is then obtained, and the solution to the MST (Minimum Spanning Tree) problem uses the Kruskal algorithm and TORA software. The results of the study showed that the minimum spanning tree cable length which was originally 1424.61 meters, after using the Kruskal algorithm manually became 1258.05 meters and also by using the POM-QM for Windows software obtained a minimum result of 1258.05 meters, so it can be concluded that there is a cable length efficiency of 11.69%.

This article is aimed at verifying a methodology for defining the load capacity of adriven hanging pile, which is part of a foundation laid on a real construction site after conducting engineering and geological surveys. The results of an automated analysis of the pile load capacity implemented in 2 software complexes (SC) – a) "Zapros" software (version 21.1.9.7), which is a part of SCAD Office software and b) with a subsystem "Statika" – a part of the complex planning system Ing+ were compared. Further, we performed a calculation analysis according to the SP 24.13330.2012 "Pile Foundations. The updated Version of SNiP 2.02.03-85", where the load capacity of a driven hanging pile is calculated as a sum of the resistivity of the foundation ground under the low part of the pile and the ground on its side surface. A comparative analysis of the obtained results established that the value calculated in SC Statika, namely in module Statika ground –concrete piles, is lower than that obtained by manual analysis according to SP (the spread is 2.19%). At the same time, the result obtained with the Zapros software produces an error higher than the normative value by 13.55%. Thus, the study has shown inconsistency in the results obtained using normative requirements and automated analysis. It can be concluded that the use of software complexes does not guarantee an entirely reliable result, thus not abrogating the responsibility of the planner and requiring additional verification.

Standardization and unification of elements, constructions and design solutions is one of the main ways to reduce the complexity and cost of the construction.Standard designs of truss coatings with a 10% slope for 24, 30, 36 meters spans were developed in this article for different load combinations.Stress calculation and truss elements dimensioning was made with the SCAD Office software complex. Then the relationship between the thickness of the section, span and load was defined, and the limits of various sizes of the accepted bottom chord connecting block.Designed series of truss structures with a 10% slope and 24, 30, 36 meters spans covers a range of line loads from 1,3 t/m to 3.3 t/m. In comparison with the truss structures series Molodechno it has a lower metal consumption by reducing the cross section of the upper chords due to vertical elements adding. Transportation of a 12-meter section falls under the category of oversized transportation.

In 2002 Persinger, Roll, Tiller, Korea, and Cook considered whether there are physical processes by which recondite information exists within the space and time of objects or events. The stimuli that compose this information might be directly detected within the whole brain without being processed by the typical sensory modalities. We tested the artist Ingo Swann who can reliably draw and describe randomly selected photographs sealed in envelopes in another room. In the present experiment the photographs were immersed continuously in repeated presentations (5 times per sec.) of one of two types of computer-generated complex magnetic field patterns whose intensities were less than 20 nT over most of the area, WINDOWS-generated but not DOS-generated patterns were associated with a marked decrease in Mr. Swann's accuracy. Whereas the DOS software generated exactly the same pattern, WINDOWS software phase-modulated the actual wave form resulting in an infinite bandwidth and complexity. We suggest that information obtained by processes attributed to “paranormal” phenomena have physical correlates that can be masked by weak, infinitely variable magnetic fields.

Full textAbstract:
Contemporary software products and services necessitate extensive accompanying information, including user manuals and documentation. The task becomes more complex in the case of graphical applications, as it requires capturing screenshots and highlighting the described elements. Attaining high-quality visual information using conventional means demands considerable effort and time, since, unlike text, raster images do not provide an interface for retrieving metadata about individual elements, necessitating programmatic extraction of such information. This study presents a software complex designed to automate and expedite this process. The primary focus is on a topological decomposition method that segments images based on topological features such as pixel brightness and proximity, enabling the segmentation of screenshots into control elements. This approach demonstrates high accuracy (96-99 %) in identifying graphical components across most tested images. The software product encompasses functions for the automatic capture of application windows, an algorithm for identifying control elements, and the capability to export the entire image or a specified region. Additionally, an algorithm for generating output templates for image insertion has been implemented. The decomposition method has exhibited effectiveness across the majority of test data. In instances with shadow effects, noise levels were recorded at a maximum of 34 %; however, in most cases, this figure did not exceed 3 %. Further research may contribute to enhancing these results. The findings of this study could prove valuable for the continued exploration of graphical user interface decomposition and the assessment of the method's effectiveness on diverse images. The developed software complex significantly simplifies and accelerates the documentation process, thereby opening new avenues in the automation of software development.

The optical behavior of devices based on thin films is determined by complex refractive index and thickness of each slab composing the stack; these important parameters are usually evaluated from photometric and/or ellipsometric spectral measurements, given a model of the stack, by means of dedicated software. In the case of complex multilayer devices, generally a number of simpler specimens (like single-film on substrate) must be preliminarily characterized. This paper introduces the reader to a new open source software for thin film characterization finally released after about 30 years of development. The software has already been used in various fields of physics, such as thin film optical filters, architectural glazing, detectors for high energy physics, solar energy, and, last but not least, photovoltaic devices.

Windows are a complex part of building design and provide a considerable benefit, including to school buildings. For the evaluation of the daylighting conditions prevailing in classrooms, the daylight factor (DF) was considered as the most appropriate parameter for indicating the quantity of admitted daylight. The DF values and CIE overcast sky were calculated using Velux Daylight Visualizer 3 software. The task of the paper is to compare various roof window openings in relation to the level of daylight in the attic, looking to optimize the use of the attic for teaching. The indoor air temperature has a general influence on comfort in the interior, in addition to daylight. In winter, the situation is not critical. The thermal insulation properties of packaging structures are sufficient. The situation is worse in summer, due to the fact that the heat-storage properties are undersized and there is excessive overheating of the indoor air. Four variants of roof windows and their influence on the overall microclimate in the attic are compared. The variant without roof windows is a suitable solution with regard to minimum overheating, but the worst situation for daylight. In order to receive even more light from the window (by moving windows to the top of the roof), we can use variant 2. Based on a combination of daylight calculations and summer temperature, a graphical dependence on window size prediction in terms of top and combined lighting is derived. This was hypothesized without shading the windows. Of course, the shading elements of these windows or cooling are expected in the summer. Finally, the energy required for cooling is compared depending on the size of the windows and achievement of the permissible temperature.

This paper focuses on using a popular microcomputer graphic design package (CorelDRAW 4.0) in conjunction with a variety of GIS/mapping software to test their capacity to transfer map images. Emphasis is placed on the advantages and disadvantages of transferring different bitmap and vector formats, rather than on the nature of the formats themselves. All of the cartographic packages tested had some capacity to export thematic maps to CorelDRAW, although some file formats provided greater flexibility than others. Generally, it appears that simpler thematic maps transfer easily, while more complex types require considerably more effort to transfer successfully. Both Windows Metafiles and Computer Graphics Metafiles proved to be efficient file formats for exporting most types of map images to CorelDRAW.

In accordance with modern requirements for the design of buildings, designers are needed to use structural solutions that are resistant to progressive collapse. A space-working caisson-type overlap is one of such solutions. Spatial constructions are repeatedly statically indeterminate systems and their calculation is performed on a computer in software complexes based on the finite element method. A ribbed model can be created from various types of finite elements and get data that varies. One of the ways to control the finite element method is to calculate structures using different models. The purpose of the work is to search for the simplest and most accurate finite element model for calculating a ribbed reinforced concrete waffle slabs.
 The work is a continuation of verification studies of SCAD models for calculating reinforced concrete waffle slabs with a size of 9.0 x 11.55 m. The bending moments in the beams obtained by the analytical method using a rod model and a model created from three-dimensional elements are compared. The values of bending moments calculated analytically and using a solid-state model have similar values. The maximum deviations of the FEM from the analytical method of calculation are from -0.9 to +11.6%. The values of bending moments calculated using a solid-state model and a rod model have similar values. The maximum deviations range from -9.7 to +6.3%. The finite element model, the calculation of which is based on solving the volumetric problem of elasticity theory, is effective, but time-consuming to create and difficult to analyze the data obtained.

One of the main and responsible stages of creating an apparatus for numerical analysis of structures using the finite element method is its implementation in the form of a set of programs. The principles of complex construction should take into account modern requirements for strength calculation software in modern calculation complexes. Among them, first of all, automation of the main stages of the computing process, rational use of the resources of the operating and external memory of storage devices, non-closedness in relation to the classes of problems to be solved, algorithms for the task of input data, the method of discretization and solution of systems of equations and etc. In addition, the structure of the programs should take into account the specifics of the semi-analytical method of finite elements, for which such a large experience of creating developed systems of mathematical support for the search of spatial structures has not yet been accumulated, as when using the traditional version of FEM. Considerable experience in solving finite element mechanics problems, accumulated over the past decades, has been reflected in a number of industrial commercial software complexes of domestic (LIRA, SCAD) and foreign (ANSYS, Nastran, ABAQUS) production. The developed finite element base of these software complexes allows you to obtain solutions to a wide range of problems of the mechanics of a deformable rigid body for objects of different dimensions, including for massive spatial bodies, and convenient means of input-output of information and processing of the obtained results make them very accessible to a wide circles of users and allow to display the obtained results with the maximum degree of visibility. There are also object-oriented complexes created at manufacturing enterprises and research institutes, for example at the Institute of Strength Problems of the National Academy of Sciences of Ukraine, at the Dnipropetrovsk National University. The conducted research will determine the most optimal ways of solving the listed problems from the point of view of computing costs and complexity of implementation, as well as outline the circle of unsolved issues.

Full textAbstract:
Patients with an asbestos-related mesothelioma may be legally entitled to financial compensation. In this context, a physician may be called upon to apportion the contribution of an asbestos containing product or facility where there was asbestos exposure in the development of that individual’s mesothelioma. This task is mathematically not simple. It is a complex function of each and the entire individual’s above-background asbestos exposures. Factors to be considered for each of these exposures are the amount of exposure to mesotheliogenic fibers, each of the asbestos containing products’ potency to cause mesothelioma, and the time period when the exposures occurred relative to when the mesothelioma was diagnosed. In this paper, the known factors related to asbestos-related mesothelioma risk are briefly reviewed and the software that is downloadable and fully functional in a Windows® environment is also provided. This software allows for rapid assessment of relative contributions and deals with the somewhat tedious mathematical calculations. With this software and a reasonable occupational history, if it is decided that the mesothelioma was due to above-background asbestos exposure, the contribution of an asbestos containing product or a time period of asbestos exposure can be apportioned.

Introduction. The deformation theory of plasticity (deformation theory) can be widely applied in physically nonlinear calculations under simple or converging to simple loadings. In particular, for the analysis of the seismic resistance of masonry buildings, the deformation theory can be utilized within the framework of the nonlinear static method. Compared to flow type theories, deformation theories enable a greater number of failure mechanisms to be implemented by defining a complex combined strength figure of the material without encountering issues with singularities in the limiting loading surfaces.Aim. To develop a variant of the deformation theory of plasticity for masonry in a plane stress state, taking into account the orthotropy of strength properties.Materials and methods. The study involved an analysis of known deformation theories. The physical relationships were formulated in matrix form for use in computer calculations. The comparison of the mathematical model with experimental results was performed using regression analysis methods.Results. A deformation theory for masonry is described as a quasi-orthotropic material without considering deformation anisotropy. The authors proposed a strength figure for masonry that accounts for the orthotropy of strength properties and depends on the angle between the principal axes and the axes of orthotropy. A methodology for transforming two basic deformation curves for masonry is outlined.Conclusions. The presented quasi-orthotropic deformation model for masonry can be utilized in finite element analysis programs and in developing plugins for existing software systems, particularly for the SCAD Office software suite with a deformation plasticity theory model.

In the modern educational process, information technologies are actively used to realize the process of acquiring knowledge at a qualitatively new level, which is especially important for distance learning. The level of their development allows to develop mathematical models of any processes and phenomena. Relay protection schemes are chosen as the subject of research. Based on their functionality, virtual stands have been developed in the MATLAB software package, which allow the user to get closer to the real conditions of laboratory work. The program “Investigation of maximum current protection” allows to investigate the operation of circuit elements as a result of a two-phase short circuit in the electrical system that consists of the generator, power line and load. The symmetric method was used to create a mathematical model of short circuit. When you start the model, windows automatically appear, in which the graphs of the dependence of the currents flowing in each phase and the state of the elements from time to time are built in the form of animations. On the basis of previously developed algorithms of operation of the current relay RT-40 and the power direction relay RBM-178 the scheme “Research of the maximum directed current protection” is developed. The virtual stand considers a two-way power supply network, which includes: symmetrical three-phase AC sources, power lines, high-voltage switches, consumers and directional current protection. To ensure greater functionality, the introduction of the necessary parameters of the elements is provided. With the help of a group of switches, you can simulate a two- and three-phase short circuit in the circuit. When starting the model, the currents flowing in the line in normal, emergency and post-emergency modes are calculated. At the end of the simulation, graphs of the dependence of the currents flowing in each phase and the state of the elements over time appear. The program “Distance Protection Research” uses algorithms for calculating currents of two- and three-phase short circuits developed in previous stands. During the simulation, a panel with the main characteristics of the relay is provided for monitoring the results and recording them. There is a graph on the stand, which shows the angular characteristics and values of resistance at different points of the short circuit. The stands have light indication – lamps color – and visual indication – contacts status.

Full textAbstract:
A software and information complex for modeling multi-node integrated and autonomous power and heat supply systems is proposed. The main difference of the proposed software and information complex is the possibility of a detailed consideration of the influence of economic and technological parameters contained in the power system of individual power units and nodes. These parameters can be presented both in the form of matrices on the sheets of the software and information complex, and in the form of separate attached files available for automated input by the software and information complex. The main advantages of the complex, which distinguish it from the known ones, include versatility, which makes it possible to study various models of energy systems in a short time. This versatility is ensured by the fact that the complex is developed using a combination of standard Microsoft Excel software and SolverStudio – an add-in for Excel 2007 and later versions on Windows, which allows you to explore a variety of optimization models using a large list of optimization modeling languages. With the SolverStudio add-in in the information package, the user can develop, edit, save, and debug an optimization model in an Excel workbook. The connection of source data, sets, parameters, constants and variables used in the model is conveniently organized. After editing the parameters and source data, the model is launched. Simulation results can be displayed both on model sheets and displayed as separate files. Another advantage of the software and information complex is the ability to conveniently compare many models, due to the fact that each of the worksheets can have its own model. The developed software and information complex makes it possible to calculate in detail the energy, technological and economic indicators of the optimal use of power system components, to determine the permissible limits of the operating parameters of power units of autonomous and integrated power systems. The results of these calculations make it possible to select appropriate measures for the future renewal of technologies for the production of electric and thermal energy. The ease of use and editing of both individual parameters and program texts used in modeling the development of power systems improves the quality of the resulting development scenarios. The proposed software and information complex can be used to study the prospects for short-term and long-term development of Ukraine, as well as the energy system integrated with the power systems of neighboring ENTSO-E member countries, which is relevant in these conditions. Keywords: software, information, complex, multi-node, integrated, autonomous, power, systems.

Full textAbstract:
Abstract Chromatin immunoprecipitation with massively parallel sequencing (ChIP-seq) is widely used to identify binding sites for a target protein in the genome. An important scientific application is to identify changes in protein binding between different treatment conditions, i.e. to detect differential binding. This can reveal potential mechanisms through which changes in binding may contribute to the treatment effect. The csaw package provides a framework for the de novo detection of differentially bound genomic regions. It uses a window-based strategy to summarize read counts across the genome. It exploits existing statistical software to test for significant differences in each window. Finally, it clusters windows into regions for output and controls the false discovery rate properly over all detected regions. The csaw package can handle arbitrarily complex experimental designs involving biological replicates. It can be applied to both transcription factor and histone mark datasets, and, more generally, to any type of sequencing data measuring genomic coverage. csaw performs favorably against existing methods for de novo DB analyses on both simulated and real data. csaw is implemented as a R software package and is freely available from the open-source Bioconductor project.

Full textAbstract:
Residential buildings and living conditions have greatly changed over the last two decades. In fact, with a few exceptions, current buildings are not the kind of habitats belonged to today. Due to the development of innovative materials, products and construction methods, the construction of environmentally friendly buildings with better economic efficiency seems essential. The present study seeks to provide simple and practical solutions to reduce energy consumption and develop comfort in residential buildings in cities influenced by hot climatic conditions. To this end, a 4-storey residential building in the city of Ahvaz, Iran, is simulated by Design Builder Software (which uses Energy plus engine) to investigate the impact of alternative roofing and facade materials, awning, windows, and others, on energy efficiency. The results show that using rockwool and aluminum composite panels (ACP) facade, pumice concrete roofing, double glazed windows, vertical awning of a 70 cm height, and a balcony of 50 cm depth are the best composition to thermal reinforcement for residential buildings and decrease energy consumption.

Full textAbstract:
Abstract Summary Transcription and DNA supercoiling are involved in a complex, dynamical and non-linear coupling that results from the basal interaction between DNA and RNA polymerase. We present the first software to simulate this coupling, applicable to a wide range of bacterial organisms. TwisTranscripT allows quantifying its contribution in global transcriptional regulation, and provides a mechanistic basis for the widely observed, evolutionarily conserved and currently unexplained co-regulation of adjacent operons that might play an important role in genome evolution. Availability and implementation TwisTranscripT is freely available at https://github.com/sammeyer2017/TwisTranscripT. It is implemented in Python3 and supported on MacOS X, Linux and Windows.

Full textAbstract:
A comparative analysis of finite element models and methods for solving complex problems of geometrically nonlinear deformation, buckling and post-buckling behavior of thin shells of stepwise variable thickness is carried out. An approach based on the use of the moment scheme of finite elements is considered. The features of using the software suite LIRA and integrated software system SCAD for solving the assigned problems are also provided. Thin and medium thickness shells are considered. They can have different geometric features in thickness and be under the action of static thermomechanical loads. A technique for solving these problems with the help of an efficient refined approach is presented. The technique is based on the general methodological positions of the three-dimensional theory of thermoelasticity and the use of the finite element moment scheme. With this approach, the approximation through the shell thickness is carried out by a single universal spatial finite element. The element can be modified in different portions of the shell with a step-variable thickness. It can be located eccentrically relative to the middle surface of the casing and can change its dimensions in the direction of the shell thickness. Such a unified approach made it possible to create a unified designed finite element model of a shell of an inhomogeneous geometric structure under the combined action of a thermomechanical load. A comparative analysis of the application of three finite element approaches for problems of geometrically nonlinear deformation and buckling of shells of stepwise variable thickness is carried out.
