BACKGROUND: Cognitive workload resulting from drivers’ engagement in concomitant tasks while driving, such as talking on a cell phone, affects the availability of attentional resources for the various stages of information processing, which can interfere with the selection of relevant traffic information, leading to poor performance and higher risk of accidents.
AIM: The purpose of this study was to test the adaptation and application of the method of fixation-aligned pupillary response averaging to the car driving context, and, if successful, to determine effects of talking on a cell phone while driving, in both handheld and hands-free situations, and effects of driving experience on pupillary responses of young adult drivers, as indicative of cognitive workload.
METHOD: Ten novice and ten experienced drivers had pupil diameter measured while driving in a car simulator under velocity of 80-120 km/h, daylight, linear trajectory and low traffic level. Data analysis was based on the method of fixation-aligned pupillary response averaging.
RESULTS: Noise curves were around baseline (zero) values while pupil dilation curves clearly stood out from noise magnitude, in all conditions for both groups. Greater pupil dilation peak during talking on the cell phone (handheld and hands-free conditions) while driving occurred only for the novice group.
CONCLUSION: Adaptation and application of the method of fixation-aligned pupillary response averaging to the car driving context succeed. Cognitive workload imposed by the dual task of talking on a cell phone increased pupil dilation for novice drivers, which may alter acquisition of visual information and impair driving behavior.
An internal model approach for motor behavior
Authors: Leite Cláudio M. F. , Campos Carlos E. , Couto Crislaine R. , Ugrinowitsch Herbert
Published: December 2021

Interacting with the environment requires a remarkable ability to control, learn, and adapt motor skills to ever-changing conditions. The intriguing complexity involved in the process of controlling, learning, and adapting motor skills has led to the development of many theoretical approaches to explain and investigate motor behavior. This paper will present a theoretical approach built upon the top-down mode of motor control that shows substantial internal coherence and has a large and growing body of empirical evidence: The Internal Models. The Internal Models are representations of the external world within the CNS, which learn to predict this external world, simulate behaviors based on sensory inputs, and transform these predictions into motor actions. We present the Internal Models’ background based on two main structures, Inverse and Forward models, explain how they work, and present some applicability.

Klasik Arap edebiyatı kaynaklarında herhangi bir temanın hangi amaçlarla kullanıldığı ancak sabırlı ve itinalı bir literatür taraması sonucu ortaya çıkabilir. Belli bir tema etrafında teşbih merkezli yapılan itinalı bir literatür taraması sonrasında ortaya çıkacak akademik bir çalışmanın ilgili alandaki araştırmacılara hem zengin bir kaynak sağlayacağı hem de klasik Arap edebiyatının kendisine özgü teşbih dünyasını tanıma fırsatı vereceği kuşkusuzdur. Bu sebeple gerek Câhiliye döneminde gerekse İslâm sonrası dönemin değişik yüzyıllarında yaşamış olan şairlere ait dîvânlar ile antoloji türü eserlerin ilgili bölümleri taranarak hazırlanmış olan bu makalede, hangi sözlerin hayranlık uyandırıp güzel addedildiği veya hangi ifadelerin çirkin görüldüğü meselesine girilmeden sadece güzel sözün benzetildiği unsurlar tespit edilmeye çalışılmıştır. Şairlerin çeşitli benzetmelere başvurarak muhataplarına ince ve anlamlı mesajlar vermeye çalıştıklarına işaret eden makalede güzel sözün benzetildiği unsurlardan özellikle edebî kaynaklarda yer alan beyitlerin sayısı dikkate alınarak birden fazla şair tarafından dillendirilenler alt başlıklar şeklinde incelenmiş diğerlerine ise icmâlen değinilmiştir. Klasik Arap şiirine bağlı kalınarak güzel sözü yalnızca benzetilen unsurlar ekseninde sistematik bir şekilde konu edinen makalenin akademik alanda göze çarpan önemli bir boşluğu dolduracağı ümit edilmektedir.

Peygamberlerin sonuncusu ve mührü olan; Allah’ın yeryüzündeki dinini tebliğiyle tamamlayan Hz. Muhammed’in sûretine ve bununla birlikte sîretine dair vasıfların bildirildiği hilyeler hem kalb-i selîmin hem de zevk-i selîmin konusu olmuşlar, yüzlerce yıl manzum-mensur şekilde edebiyatımızı süslemişlerdir. Böylece Müslümanlar yüzlerce yıl O’nu resmetme ihtiyacı bile duymadan bu hilyelerle âdeta terbiye edilmişlerdir. Hilyeler yazılırken Hz. Peygamber’in sûretine ve sîretine dair hadis rivâyetleri esas alınmıştır. Bu rivâyetlerdeki kelimeler o dönemin Arapçasında bile fazla kullanılmayan kelimeler oldukları içindir ki şerhe ihtiyaç duyulmuştur. Yapılan bu şerhlere Osmanlı Türkçesi ile yapılan şerhler ise Türk-İslâm edebiyatında hilye-i şerîfeler olarak bir edebî türe dönüşmüşlerdir. Bugüne kadar hilyelerle ilgili olarak yapılan çalışmalarda daha çok manzum hilyeler üzerinde durulmuştur. Bu çalışmada ise mensur hilye örneklerinden hattat, devlet adamı Vahdî İbrâhîm’e (ö. 1126/1714) ait olan ve tespit edebildiğimiz dört nüshalı Terceme-i Hilye-i Şerîfe şerhi çeviri yazı ile birlikte verilmiştir.
Arap Dilinde Müphem Lafızlar ve Delâletleri
Authors: AKTAŞ Osman
Published: December 2021

Arap dilinde bazı kelimeler vardır ki tek başlarına kullanıldıklarında delâlet ettikleri anlam açık bir şekilde ortaya çıkmaz. Tek başlarına kullanımlarında anlam bakımından bir kapalılık söz konusudur. Bu tür kelimelere müphem lafızlar denir. Müphem lafızların anlamlarındaki kapalılığın ortadan kalkması için başka kelimeler veya cümleler ile kullanılmaları gerekir. İsm-i mevsûller, işaret isimleri, soru isimleri, şart edatları, zamirler, müphem zarflar ve temyîze ihtiyaç duyan kelimeler müphem lafızlardandır. Ayrıca ancak isim tamlamasında muzaf (tamlanan) olarak kullanılabilen bazı kelimeler de müphem lafızlardan sayılır. İsm-i mevsûller sıla cümlesine, işaret isimleri işaret edilen isme (müşârun ileyhe), zamirler de müphemliği ortadan kaldıracak mercî‘e ihtiyaç duyduğu için müphem lafızlardan sayılmıştır. Soru isimlerinde sorulan şeyin belli olmaması, şart isimlerinin belli bir şey için gerçekleşmemesi, temyîze ihtiyaç duyan kelimelerin anlamının kapalı olması, müphem lafızların sınırları, başlangıç ve bitiş noktası belli olmayan zaman ve mekâna delalet etmesi, müphem kelimelerin muzâfun ileyhe ihtiyaç duymasından dolayı bahsi geçen kelimeler müphem sayılmıştır. Bu çalışmada Arapçadaki müphem lafızlar Türkçe karşılıkları ile ele alınmıştır. Böylelikle bu çalışmanın karşılaştırmalı bir çalışma olması hedeflenmiştir.

Published: December 2021

This paper investigates a fuzzy reduced-order filter design for a class of nonlinear partial differential equation (PDE) systems. First, a Takagi-Sugeno (T-S) fuzzy model is considered to reconstruct the nonlinear PDE system. Then, the employment of an event-triggered mechanism (ETM) can effectively avoid signal redundancy and improve network resource utilization. Furthermore, based on the advantages of the fuzzy model and ETM, several Lyapunov functions are designed and the proposed filter parameters are obtained by adopting linear matrix inequality methods to satisfy the asymptotic stability condition with H∞ performance. Finally, a simulation example is presented to demonstrate the practicality and effectiveness of the proposed filter design method.

Authors: Nochnichenko Ihor , Jakhno Oleg
Published: December 2021

The article discusses the energy analysis of transfer processes in the damping system. The basic theoretical foundations based on the equations of the energy balance of the hydraulic shock absorber and the law of conservation of energy are presented. The proposed approach is associated with the development of a methodology and scheme for calculating the technical system of vibration damping. The schemes of interaction of the system through the phenomena of transfer and functioning of the vibration protection system with the environment are presented. It is shown that damper systems are based on the physical process of transformation of mechanical energy into thermal energy with subsequent dissipation into the environment. The total energy distribution in damping problems takes the following form the mechanical energy of motion is absorbed due to the hydraulic resistance of the liquid and turns into a dissipative component, which can reach 80% of the total energy. A mathematical model of the law of conservation of energy is presented which includes a dissipative function. The analysis of how it is possible to design work processes in a shock absorber due to energy dissipation and similarity criteria: Euler, Froude, Reynolds, etc. As a result of physical experiments, it was found that the movement of a fluid in hydraulic calibrated throttles gives rise to cavitation and various physical phenomena and accompanying processes, in which there is a significant change in the energy balance and energy dissipation in non-stationary modes of fluid movement.

The dependence of the total power loss of the shock absorber under changing operating conditions, and the diagram of physical processes and energy transformations in the problems of damping, which are in dissipative processes, are given. The article describes the principles that can be used for the design of devices and modules of damper systems of a wide class with the possibility of energy recovery and accumulation by introducing a damper into the system, for example, a motor generator, an inductor with permanent magnets or a peso element in the design of a traditional telescopic shock absorber.

Published: December 2021

The work is devoted to the development of an innovative technology of stamping from low-carbon steel for small-size liner blanks. The sequence of punching transitions includes a cold back extrusion operation, two cold drawing operations with thinning, and a cold crimping operation. Simulation with the use of the finite element method established the forces and specific forces during operations, the thermal effect during shaping, the shape and size of semi-finished products with distributions of the intensity of deformations. An elastoplastic metal model was used, which made it possible to reveal the deformation forces, tool extraction from deformed semifinished products and the effort to remove semifinished products from the dies. A hollow semi-finished product is obtained by reverse extrusion. The possibility of carrying out the first drawing operation with thinning through two sequentially located dies with the formation of a hole in the bottom part is shown. After this operation, annealing of the semi-finished product is required to restore plasticity. In the second operation, thinning stretching. The shape and dimensions of the wall of the semi-finished product after the second drawing, the distribution of the intensity of deformations in it are determined from the condition of reaching the final dimensions and mechanical properties of the sleeve blank at the last crimping operation. For this, the deformations obtained as a result of the second drawing are taken into account when modeling the crimp. For each transition of stamping, a construction of stamping equipment has been developed. The proposed technology for stamping a sleeve blank can be implemented on a universal pressing equipment, has a high productivity due to a reduction in the number of transitions and minimizes mechanical processing.
TO THE QUESTION OF ANALYSIS OF EQUATIONS OF MOTION OF A RIGID BODY DURING THE MECHANICAL OSCILATIONS
Authors: Bernyk Iryna
Published: December 2021

Depending on the current position of the mass in different areas of the spring deformation during the oscillation process the values that determines the natural frequency of free continuous oscillations have opposite signs. It is defined by the change in the direction of acceleration of the mass in these areas, which makes it possible to determine a single inhomogeneous differential equation of the oscillation process in different areas of the movement of the mass. When the oscillation amplitude is much less than the static position of the mass, this inhomogeneous differential equation represents a homogeneous differential equation of free undamped oscillations.

Published: December 2021

Problems. In the process of obtaining a strip in a casting and rolling device, the question arises of combining the process of hot rolling of the solidified material and the process of crystallization of the liquid melt. This makes it possible to implement an efficient technology for producing thin-sheet products.
Purpose of the study. Determination of rational parameters for performing mathematical modeling of material behavior during roll casting requires clearly defined recommendations. The material for the rolling process is steel. The starting material was used in solid, solid-liquid and liquid states.
Implementation technique. The analysis of the properties of steel was carried out on the basis of the results of experiments obtained at the Physico-Technological Institute of Metals and Alloys of the National Academy of Sciences of Ukraine. To analyze the rheological properties of steel, the dependences of the yield stress for alloyed and carbon steels were used in a certain temperature range. The selected temperature range includes solidus and solid-liquid state of steel, located above 0.8 melting point.
Research results. Based on the research results, the analysis of the rheological properties of steel in solid, solid-liquid and liquid states during continuous casting-rolling on rolls was carried out. The use of the obtained dependencies makes it possible to perform mathematical modeling of the deformation and hydrodynamics of the material during continuous casting-rolling of steel strips using roll casting-rolling devices.
Conclusions. The constructed dependences, together with studies of the viscosity of steel in the liquid state and the resistance of steel to deformation in the solid state, most fully describe the rheological properties of steels during casting-deformation processes. The obtained dependences will make it possible to implement an ultra-efficient technology for producing thin-sheet rolled products.

Published: December 2021

There have been emerging issues toward the increasing amount of zakat collection and the slower pace of zakat distribution (Lubis et al., 2011). These issues create dissatisfaction which increases negative perception towards Zakat Distribution Organizations (ZDOs) amongst the zakat payers (Yusof, 2010). The objective of this study is to assess the strengths, weaknesses, opportunities, and threats of ZDOs. The methods used in this study were document analysis and Focus Group Discussion (FGD) conducted among the employees of ZDOs. Findings from this study showed that the strengths are related to the aspects on human resource management, the stable financial sources, the broad network, the good organizations setup, the positive work culture among staff members, as well as opportunities for learning and development for ZDOs employees. The weaknesses of ZDOs are associated with workplace condition, staff members’ attitudes and work performance, and management system. In addition, external environment provides a significant opportunity for the organizations. Proactive distribution of zakat and collaboration with other agencies are external aspects that can be leveraged in order to improve the functions of ZDOs. The identified threats are the ZDOs’ surrounding, the attitudes of zakat recipients towards ZDOs, competition from outside parties, public dependency, and external interferences. These findings are expected to provide baseline information to guide ZDOs in designing change initiatives that will be effective and efficient in increasing both work and organizational performance.

During the economic crisis occurring in Indonesian, entrepreneurial sector has been the solution for Indonesian economic downturn. Until the current time, entrepreneurship keeps becoming the cornerstone for the government in improving Indonesia economic growth. However, entrepreneur women face more specific obstacles which complicate their steps, then it causes the fact that there are more entrepreneur women have contributions in Indonesian economic growth (60%) is less exposed (Tjahjadi et al., 2019). The study is aimed to identify the relationship between adversity quotients with entrepreneurial intentions of entrepreneur women. The hypothesis proposed in this study is that there is a positive relationship between adversity quotients with entrepreneurial intentions of entrepreneur women. The research subjects were 100 batik entrepreneur women. The scale used in this study was made based on the aspects of the Theory Planned Behavior (TPB) by Ajzen for the entrepreneurial intention variable and aspects of the Adversity Response Profile (ARP) by Stotlz for the adversity quotient variable. The hypothesis test result using Pearson's product-moment showed a correlation number r of .497 and p = .000 (p < .01). It indicates that there is a significant relationship between Adversity Quotient and Entrepreneurial Intensity so that the proposed hypothesis is accepted. The implication of the research is for encouraging the entrepreneur women to create solution to overcome adversities in developing the business.

Published: December 2021

I propose two modifications of the SIR model of the epidemic spread, taking into account the social and space heterogeneity of the population. Social hetero¬geneity associated with differences in the intensity of paired contacts between people qualitatively changes the basic reproductive number. Space heterogeneity associated with differences in the intensity of multiple contacts between people significantly shifts the equilibrium position, increases the characteristic times and leads to the emergence of oscillatory dynamics of finite duration.

The features of the hardware and technological design of the AM-1360 series ammonia synthesis units operating in Ukraine are established, the main of which is the use of heat-using ammonia-water absorption and refrigeration units in the secondary condensation complex. The analysis of the functioning of the absorption and refrigeration units has been carried out. A significant dependence of their efficiency on external disturbances, such as temperature and humidity of atmospheric air, has been established. This causes significant fluctuations in the cooling temperature of the circulating gas in the evaporators of absorption-refrigeration units, which significantly affects the efficiency of ammonia production in general. Based on the results of the analysis of the existing information system, implemented on the basis of the TDC-3000 microprocessor complex, recommendations for its improvement were developed, the presence of which makes it possible to abandon daily analyzes and carry out only control ones to check measuring instruments.

Algorithmic support has been developed, implemented in the MATLAB package and tested according to the data of industrial operation of absorption and refrigeration units of the ammonia synthesis unit. This allows the operator, in real production conditions, to obtain operational information on the numerical indicators of the efficiency of operation of absorption and refrigeration units, which characterize their operation to the greatest extent (circulation rate, cooling capacity, circulating gas cooling temperature and thermal coefficient) and make a decision on the possibility of reducing the cooling temperature. of circulation gas in evaporators by changing the frequency of circulation of solutions The created algorithmic software in the MATLAB environment allows embedding a client module, the so-called OPC client. The latter provides technology for free programming of access to current data.
OBTAINING DIESEL FUEL WITH IMPROVED PROPERTIES

It is known that one of the ways to increase the level of operational properties of diesel fuels is the injection of special components – additives – into their composition. Today this way is a quite rational and economically feasible for Ukraine, especially in the absence of high-quality oil raw materials for the production of fuels, which in turn leads to a significant dependence on imports.

The range of additives used in diesel fuels is very diverse, which makes it difficult to select a balanced package, especially considering their effectiveness and compatibility with each other. This procedure can be a bit simplified by adding poly-functional additives to diesel fuel, the use of which is devoted to a lot of periodical literature.

Based on the relevance of the direction of scientific research related to improving the properties of diesel fuel, which is produced at the enterprises of the oil refining industry in Ukraine, we proposed to use a substance belonging to the class of aromatic diazocompounds and having polyfunctional properties in the composition of diesel fuels. Thus, this additive was added to a straight-run diesel fraction (240–350 °C) in an amount of up to 1.0%, followed by a study of the properties of the resulting mixture. Studies have shown that the additive significantly improves low-temperature properties (by -10 °C), contributes to an increase in fuel density and viscosity, and additionally gives diesel fuel a stable color (from yellow to orange). Consequently, it can be used in the composition of commercial diesel fuels with improved performance properties.

Modern CFD methods for calculating combustion processes make it possible to take into account changes in temperatures, heat loads, rates of coolants, as well as further changes in fuel quality. To develop the skills of CFD design and understanding of combustion processes among future specialists in thermophysical specialties, work was carried out to simulate the burner device of a waste heat boiler. For the study, the design of the gas burner of the waste heat boiler RB-70-4.0-440, which operates as a part of the power unit at the LLC “Rubezhansky Cardboard and Container Plant” in the city of Rubezhnoe, was selected. When constructing a geometric model, the hydraulic resistance to the flow of the supply and distribution manifolds was taken into account. To simplify the calculations, the problem was carried out in a two-dimensional, axisymmetric formulation. Analyzing the computational combustion models, the Non-Premixe Combustion model was chosen, which made it possible to take into account the entry of fuel and oxidizer into the reaction zone by two different flows, as well as turbulent diffusion flame propagation. Six variants of models were investigated: the first three variants with a flame tube with a solid disc with diameters of 32, 48, 56 mm, the next three variants, had a burner with a discontinuous disk 32 mm in diameter at a distance of 6, 16, 32 mm from the flame tube. As a result of the research, the optimal shape of the burner was chosen, which corresponds to model 4, and provides a high-quality combustion process, as evidenced by the high temperature of the torch and the lowest temperature at the disk. The conducted research gives future masters the skills of modeling combustion processes in power equipment.

The article is devoted to topical issues related to the storage, accumulation and transportation of heat by stationary and mobile heat storage. Analysis of the current state of the district heating system indicates significant heat losses at all stages of providing the consumer with heat. The use of heat storage in heat supply systems leads to balancing the heat supply system, namely, the peak load is reduced; heat production schedules are optimized by accumulating excess energy and using it during emergency outages; heat losses caused by uneven operation of thermal equipment during heat generation are reduced; the need for primary energy and fuel consumption is reduced, as well as the amount of harmful emissions into the environment. The main focus is on mobile thermal batteries (M-TES). The use of M-TES makes it possible to build a completely new discrete heat supply system without the traditional pipeline transport of the heat carrier. The defining parameters affecting the efficiency of the M-TES are the reliability and convenience of the design, the efficiency and volume of the “working fluid”, the operating temperature of the MTA recharging and the distance of transportation from the heat source to the consumer. The article contains examples of the implementation of mobile heat accumulators in the world and in Ukraine, their technical and technological characteristics, scope and degree of efficiency. The technical indicators of the implemented project for the creation of a mobile heat accumulator located in a 20-foot container and intended for transportation by any available means of transport are given.

Analysis of literature sources suggests that the use of anaerobic treatment methods is especially effective for high concentrations of contaminants in wastewater, as well as for large volumes of water supplied for treatment, which is typical for industrial wastewater. In biotechnological production and food industry, waste water has a high level of pollution with organic compounds, it is advisable to use anaerobic treatment methods. Anaerobic wastewater treatment processes are characterized by low energy consumption and the ability to recover energy through the combustion of methane. To ensure the required temperature regime for the operation of the bioreactor, a new design of the heat exchange device of the anaerobic bioreactor with immobilized microorganisms has been developed. This design of the bioreactor can provide the required degree of wastewater purification at significantly lower costs for construction, operation, and material and energy resources. For clarity, the design features were designed bioreactor with a plane load of bundled software SOLIDWORKS and a mathematical model of the processes of anaerobic wastewater treatment.

This scientific paper gives the main research data obtained during the solution of the search problem to define optimal parameter values for the thermal circuit of the К-540-23.5 turbine unit that would provide the most efficient operation both for the optimal version of the high pressure cylinder (HPC) as part of the turbine unit and the turbine unit on the whole. The effect of the distribution of heat differences in the stages of the optimal flow part of the high pressure cylinder used by the К-540-23.5 turbine on the integral quality factors of the turbine unit has been assessed. The calculation studies of the thermal circuit of the turbine unit with the optimal flow section of the high-pressure cylinder showed that the temperature of the underheated feed water in the high pressure heater (HPH) arranged near the steam generator has the most critical effect on the power and economical efficiency of the high pressure cylinder and entire turbine unit. The two-criterion Pareto problem for the upgrading of the turbine unit was formulated and solved to define optimal underheating temperature values. Consideration was given to the two variants of the solution of the optimization problem for the feed water underheating temperature in the high pressure heater. Comparison and analysis of the two variants of solution for the two-criterion optimization problem showed the identity of the obtained data and it confirms the correctness of the problem formulation and the algorithms used for its solution.
