AB  - The paper presents the integrated application of two methods during testing HVAC system efficiency in the cabins of HUMMER.1151A1 and OAR 1RL-128D offroad vehicles. Spatial measurements of change in air temperature per time have been performed at three vertical levels (head, knees, and feet) of the driver and passengers, which totals to 15 measuring points per vehicle. The main goal of testing was to evaluate accurately the efficiency of heating and cooling in relation time interval required to attain a designed temperature of comfort in the vehicle cabin, on condition that the difference in ambient temperature levels does not exceed 10 degrees C. With a view to more efficient evaluation of thermal comfort in vehicle cabins, the testing was performed also of predicted mean vote and predicted percentage of dissatisfied indices. Standard thermal comfort surveys ask subjects about their thermal sensation on a seven-point scale from cold (-3) to hot (+3). This research is carried out according to the methods based on ISO 7730, ASHRAE 55, and SORS 8419 standards.

AB  - Educated and talented people drive progress in every country. That’s why no country can neglect these people; that would mean losing one’s own potential. This paper emphasises the importance of educating scholarship students abroad as a means of developing and accumulating human resources and a key determinant of sustainable development in the modern world. Investing in the education of the best students (scholarship holders) is an investment in the future, which brings multiple benefits on a social, economic, and political level. Migration is an important phenomenon that attracts public attention, especially when it comes to highly educated experts leaving their home country in search of better education. Highly educated experts have been leaving Serbia for several decades, which poses an obvious problem for local society. The topic of permanent migration is dominant both in foreign and domestic literature, but studies on the temporary migration of highly educated students (scholarship holders) is almost nonexistent. The aim of this paper is to point out the value of returnee scholarship holders and the importance of creating the appropriate conditions for them to stay in the country. A survey conducted on a group of 96 returnee scholarship holders identified factors that affect their satisfaction with living in Serbia. The survey involved experts from Serbia who were educated abroad as scholarship holders, where they acquired academic titles and are now employed: as faculty teachers (32); as researchers at scientific institutes (24); in the private sector (21); at universities (12); in state administrative departments (5); and in medical institutions (2). The criterion for selecting this group of respondents was that they had stayed abroad as scholarship holders, whether they used scholarships from domestic (24) or foreign (72) funds. Scholarship students go abroad mostly because of their personal aspirations for training, gaining new experiences, and because of the inability to study the desired discipline in their country, as was the case for 74 respondents. The main reasons for deciding to return are family (25) and the belief that they have a good chance to work in Serbia (18), while 16 respondents could not stay abroad. In this paper, we used the factor analysis method. The main factors that create satisfaction with life in Serbia are isolated. These factors are: satisfaction with work and a set of factors that strongly correlate with it (the ability to make decisions, the implementation of acquired knowledge, peer acceptance), as well as the recognition of their diploma in Serbia without any difficulties. By improving these factors, there might be a significant increase in the chance that returnee scholarship holders remain in Serbia for a long time. Based on this, it would be wise to build a strategy on how to encourage returnee scholarship holders to stay in the country. The results obtained in this study represent a contribution to a search for a strategy that will attract, involve, and retain educated people in the country.

AB  - Auxiliary machinery is used at the open-pit coal mine (machines: bulldozers, trench excavators, pipe-laying machines, ...) for performance of auxiliary work (excavation, construction of route, ....) in order to provide an uninterrupted operation of the basic machinery for excavation of waste rock and coal. Machines are moving from one area of the open-pit to another. Movement of machines along the open-pit is limited space-wise by conveyor belts serving for conveyance of waste rocks and coal, including other natural obstructions (steep slopes, mud, water). These obstructions affect the open-pit machines' length of trajectory, duration of movement and consumption of fuel. Observing the said problem, a model for optimizing the "movement" of open-pit auxiliary machinery has been developed and applied with ICT, namely GPS/GPRS and appropriate software solution, as presented herein. Model determines the "shortest" path of the machine to the job which can result in significant fuel savings and reducing failures of machines.

AB  - The applied stress level which will produce plastic deformations in WM is lower than the BM yield strength, not to mention effect of over-loading. One should also keep in mind that welded joints are places with non-uniform stress distribution because of stress concentration even if residual stresses are released. Therefore, simultaneously introduced different influencing factors will produce difficulties for stress calculation of welded joints, so that the design of pressure vessels becomes more complicated than usual. Sometimes, it is inevitable to test the produced pressure vessel, using different techniques, needed for stress calculations and assessment of weldments behaviour under different service conditions.
Reversible HPP (RHPP) “Bajina Basta” is in operation since 1982, [2]. Taking into account that the failure of the most critical part, the pipeline (Fig. 1), would cause water overflow of the surge hub in the surrounding area, and the collapse of the entire plant, it is clear that special attention is still need to prove its structural integrity [3]. One of the most important effects is the proof testing, i.e. over-pressure, which is the main concern in this paper. Namely, there is a history of welded joint failures due to proof testing, e.g. spherical pressure vessels for liquefied natural gases (LNG)  [4], caused by unnecessary plastic deformation acting as crack initiation and propagation mechanism. Some details are given below, as taken from monograph [3]..
It is shown, using different approaches, that the effect of over-pressure is detrimental from the point of view of structural integrity of pipeline in RHPP.  Two approaches, one more sophisticated (micromechanical modelling), and the other, simpler one (FAD), lead to the same conclusion, that proof over-pressure is unnecessary challenge to the safety of the critical component in a very important power plant.

AB  - Informacije iz stručne literature, kao i iskustveni podaci, pokazuju da veliki procenat energetskih gubitaka termoelektrana potiče od sistema trakastih transportera i njihovih ključnih komponenti – transportnih (nosećih) valjaka. Zato su upravo ovi sklopovi, čija je funkcija da prenesu opterećenje usled mase transportne trake i transportovanog tereta na noseći ram, izabrani za objekat istraživanja disertacije. Sa ciljem povećanja pouzdanosti, i smanjenja finansijskih i energetskih gubitaka uzrokovanih neplaniranim otkazima, razvijene su nove i unapređene postojeće eksperimentalne procedure za ispitivanje ključnih karakteristika transportnih valjaka – objedinjene u kompleksnu eksperimentalnu metodologiju ispitivanja. Među razvijenim procedurama, po značaju se posebno ističe procedura za ispitivanje radnih karakteristika kotrljajnih ležaja (kritičnih komponenti transportnih valjaka) – pod dejstvom kontaminirajućih čestica sa površinskih kopova uglja. Naučne hipoteze predstavljene disertacije se odnose upravo na ovu proceduru, odnosno, naprednim statističkim metodama (primenom softverskih paketa najnovije generacije) je pozitivno odgovoreno na pitanje da li postoje statistički značajne zavisnosti između posmatranih radnih karakteristika veštački kontaminiranih kotrljajnih ležaja – vibracija, temperatura i vremena rada. Utvrđene statističke korelacije su potom implementirane u postojeću jednačinu za proračun radijalnog zazora kotrljajnih ležaja. Prema razvijenoj eksperimentalnoj metodologiji je ispitan veliki broj uzoraka transportnih valjaka, različitog tipa, proizvedenih od različitih proizvođača. Nakon analize i diskusije dobijenih rezultata, poređenjem sa iskustvenim podacima iz prakse i rezultatima do sada realizovanih istraživanja u predmetnoj oblasti, razvijena metodologija je uspešno verifikovana, pa se može dalje primenjivati za procenu kvaliteta transportnih valjaka i njihovih kotrljajnih ležaja.
AB  - Relevant literature, as well as practical experience, has shown that large percentage of thermal power plant energy losses is caused by overland conveyor systems and their key components – conveyor idlers (rollers). That’s the main reason why this assemblies, with function to transfer the load from the conveyor belt and transported material to the supporting frame, are chosen as an object of research presented in this dissertation. In order to improve reliability and decrease financial and energy losses due to unplanned maintenance, a new conveyor idlers testing procedures were developed (some of existing were improved) – and joined in complex experimental testing methodology. Among developed testing procedures, experimental procedure for conveyor idler’s rolling bearings testing is the most important – because it provides the information about the influence of exploitation contamination particles (from the open pit coal mines) on rolling bearing’s operational characteristics. Scientific hypothesis presented in this dissertation are related primarily to this experimental procedure. It was confirmed that statistically significant correlations between artificially contaminated rolling bearing’s vibrations, temperatures and time in operation could be established. One of generated correlation was afterward implemented in existing equation for rolling.

Upravljanje vodenim resursima Izraela, jedan od najboljih pokazatelja svetske strategije budućnosti. Kratkoročno i srednjeročno gledajući, desalinizacija može samo pridodati postojećim izvorima i dopustiti Izraelu da ispuni zahteve u doba suša koje se dešavaju sve češće s obzirom na klimatske promene. Desalinizacija može imati značajne posledice na okolinu, a mnoge od tih posledica nisu potpuno jasne. Izraelci danas ostvaruju svoj projekat National Water Carrier, koji navodnjava čitavu zemlju sve do pustinje Negev. Sa preko 120 postrojenja jedan od najvažnijih projekata je vodoobnavljanje - projekat prečišćavanja otpadnih voda, kojim je Izrael jedna od vodećih država u svetu. Prečišćavanje vode počelo je 1969. pročišćavanjem otpadnih voda južno od Tel Aviva prerađujući oko130 miliona metara kubnih otpadne vode godišnje. Izrael danas obrađuje veliki deo svojih otpadnih i kanalizacijskih voda. Prerađuje blizu  350 miliona metara kubnih, otpadna voda koja se  ponovo koristi za agrikulturu. Izrael je vodeća država u svetu po stopi prerade otpadnih voda. Kao država sa 60% pustinje, Izrael je oduvek imao problem sa nedostatkom vode. Izraelski institut za nauku predstavio je dostignućima u očuvanju i maksimalnom iskorišćavanju vode. Zahvaljujući tome Izrael ima i do četiri žetve godišnje, a svakodnevno se komad po komad pustinje pretvara u obradive njive, što predstavlja osnov održive privrede države.

AB  - The main goal of this paper was to pay attention on possibilities and advantages of clean solar 
energy using in the ecology campus, as an isolated system, with the respect to the intachable 
environment. The mini solar power plant was installed in a region with the high number of 
sunny days per year. This experimental installation, consisting of solar panels with capacity of 
200W, was in operation for more than one and a half month. Data regarding the total 
generated electric power were recorded and diagrams of connections of the following 
consumers were developed: incandescent light bulb, fluorescent light bulb and two 
refrigerators of different electric power. These data and diagrams are presented in this paper, 
including the cost of the energy production and environmental advantages. The problem and 
limitations of switching on are presented in this paper to. Based on certain experiment results, 
the system operation is optimised and possible improvements of power supply to this type of
an isolated system are proposed.

AB  - The main objective for the conducted research presented in this paper was to quantify, analyze 
reversibility of the algal bloom process and present changes in water quality parameters in the 
function of time, depth and temperature in reservoirs. The motive is to meet the water quality 
criteria for lake water intended for water supply at all times. The example of Ćelije reservoir 
was used to depict the correlation between the protection regime in sanitary zones and 
reservoir water quality over time. Kruševac Town is supplied with drinking water from the 
reservoir subject to the research, i.e. from its 41·106m
3
of lake water, after treatment in a 
water treatment plant. The research covered water analyses in the period after algal bloom, as 
well, with the goal to quantify the level of autoregeneration. The lake eutrophication process, 
as a consequence of multiple pollution, i.e. import of nitrogen and phosphorous compounds, 
resulted in domination of Cyanobacteria or, in fact, permanent blooming. The conclusion is 
that continuous preservation of water quality in water supply reservoirs may be achieved only 
with imperative regular monitoring and observation of strictly defined preventive measures 
for all the sanitary protection zones.

Nivo vode u tim akumulacijama je približno 400m viši od nivoa vode u Đerdapskom 
jezeru. Hidroelektrana Đerdap 3 je reverzibilno pumpno akumulaciono postrojenje, 
koje treba da bude izgrađeno na 1007 kilometru Dunava, četiri kilometara uzvodno 
od Lepenskog Vira i oko 100 km vazdušne linije od Beograda. Koncepcija rešenja 
sastoji se u tome da se voda zahvata iz Đerdapskog jezera sa kote 68, pumpa u 
gornje predviđene bazene "Pesača" i "Brodica", kada elektroenergetski sistem Srbije 
raspolaže viškom električne energije. Ako se dogovori saradnja sa stranim

conditions back to the zero stage, the way they were before the construction was built, open the question of hydropower facilities removal from the a riverbed after a given exploitation period. Compromised or endangered stability of a construction can also result in need for premature removal of the facility, before the planned exploitation period is over. The aim of this paper is to present the complexity of one hydro power plant removal project towards sustainability and holistic management of environmental quality. The total cost of structure removal is calculated and compared with the total cost of its construction. There is also a discussion on question of who should bear the expenses of the removal project and recommended answer to a decision maker from a sustainable development point of view. Simulation of removal has been done on example of gravity dam and hydropower plant Paunci on the Drina River in Serbia.

AB  - Purpose – This paper aims to define and theoretically analyse the performance of modern
methods investigated to speed up the recultivation process of degraded areas, and apply it into
the mining basin, open pit mines, tailings and all other areas, which need environmental quality
improvement.
Design/methodology/approach – This paper presents methods of conservation and substitution of
natural resources for the purpose of faster land recultivation (reclamation) in degraded coal mine
areas. Two types of methods have been developed: forest slope recultivation and agricultural
recultivation of flat landfills. Indicators of positive changes include: changes in chemical properties of
tailings, increase in biogenic properties and changes in biodiversity.
Findings – The research results show that the application of these methods, along with the holistic
approach and adequate investment, can significantly contribute to the length of recovery process and
accelerate it.
Research limitations/implications – Mining basin Kostolac is used as a model test. The results
can be applied on all mining basin, open pits and any degraded area.
Originality/value – All results and conclusions were drawn, based on the original measurements
and experiments. Stake holders, wanting to manage environmental quality after exploitation in mining
basin, applying those methods, can find the value of this paper.

AB  - The paper focuses on an investigation into the possible causes of the bad dynamic performance of bucket wheel excavator C7OOS (BWE) discharge boom in the Kolubara opencast mine, Serbia. A discharge boom load carrying structure model was produced and its static and dynamic calculations were made by the finite element method (FEM). The model was then validated by the experimental method - vibration analysis. The set goals were achieved by the FEM result analysis, which were further confirmed in the experiment. The causes for discharge boom weak performance were established. The main operation problems were found in the inadequate design of the discharge boom tie(s) and the subsequent installation of a steering cabin. Possible discharge boom reconstructions were considered with a view to improving its operation performance. The selection of the reconstruction approach was limited by the technical and financial resources available to the machine users. After the completed reconstruction, the discharge boom improved operation performance was demonstrated in practice.

AB  - Since the driver obtains important feedback of a vehicle's dynamics and its braking capabilities depending on the change of brake performance, it represents an important aspect of a vehicle's performance and its quality of use. Sensitivity of braking torque vs. the friction couple interaction, under different braking conditions, is one of the most important properties of the disc brake. In this paper, we investigated possibilities for an intelligent dynamic optimisation of automotive braking system performance. The hybrid neuro-genetic optimisation model was developed in order to perform dynamic control and optimisation of the disc brake performance during a braking cycle. This model provided stabilisation of the brake performance and their maximisation vs. the brake pedal travel, selected by the driver, and the influence of the initial speed during a braking cycle. The model provided the disc brake actuation pressure which is adjusted upto the level that provides stable and, for current braking regimes, maximum braking torque values.

AB  - The basic problem of automotive brakes operation is the decreasing of their performance at elevated temperatures in the contact of friction pair (brake disc and brake pad). Increasing of the brake interface temperature often causes decreasing of braking torque during a braking cycle. In order to provide the stable level of braking torque during a braking cycle, the neural network based optimization model of the disc brake performance has been developed. The dynamic neural networks have been employed for modelling of complex synergy of tribological phenomena that affects the final disc brake performance at elevated temperatures. The dynamic optimization neural network model of disc brake performance at elevated temperatures has been developed using recurrent neural networks. It predicts the braking torque versus the dynamic change of the brake actuation pressure, sliding speed and the brake interface temperature in a braking cycle. Genetic algorithms were integrated with the neural network model for optimization of the brake actuation pressure in order to obtain the desired level of braking torque. This hybrid, neuro-genetic model was successfully used in optimization of the brake hydraulic pressure level needed to achieve the maximum and stable brake performance during a braking cycle.

AB  - Monitoring, modeling, prediction, and control of the braking process is a difficult task due to a complex interaction between the brake contact surfaces (disc pads and brake disc). It is caused by different influences of braking regimes and brake operation conditions on its performance. Faster and better control of the braking process is extremely important in order to provide harmonization of the generated braking torque with the tire-road adhesion conditions. It has significant influence on the stopping distance. The control of the braking process should be based on monitoring of the previous and current values of parameters that have influence on the brake performance. Primarily, it is related to the disc brake actuation pressure, the vehicle speed, and the brake interface temperature. The functional relationship between braking regimes and braking torque has to be established and continuously adapted according to the change of mentioned influencing factors. In this paper dynamic neural networks have been used for the purpose of modeling and control of the disc brake actuation pressure. Parameters of the developed dynamic neural model were used to build a program for implementation in a microcontroller. Recurrent neural networks have been implemented in 8-bit CMOS microcontroller for control of the disc brake actuation pressure. Two different models have been developed and integrated into the microcontroller. The first model was used for modeling and prediction of the braking torque. Based on that, the second inverse neural model, has been developed able to predict the brake actuation pressure needed for achieving previously selected (desired) braking torque value.

AB  - Transport of ground and coal at the surface coal dig in Kostolac, Serbia, is done using transportation belts (3 - 5 kilometres in length) using the systems of BTR (Bagger-Transporter-Remover) and BTM (Bagger-Transporter-Mill). The transporter belt during circular movement is suspended on carry-rollers (during transport of weight) and on support-rollers (without weight). Two or three carry-rollers, or three support-rollers make a garland. Garlands (5 carry and 3 supporting) are built into a section and they enable the movement of belt over them. The number of sections depends on the transportation system length. Reliability of these systems is governed by the reliability of the carry and support rollers. In order to determine the reliability of the BTR and BTM systems, reliability analysis of both carry and support rollers was performed using the method of Fault Tree Analysis (FTA) and Reliability Block Diagrams (RBD). In this paper the assessment of roller reliability is described using the FTA method with failure elements. The reliability function was determined on the basis of the RBD in the case where all of the constructive elements of the rollers are in operation - the complex relationship, and when some of the elements are in failure mode - the quasi-complex relationship.

AB  - Due to complex and nonlinear dynamics of a braking process and complexity in the tire-road interaction, the control of automotive braking systems performance simultaneously with the wheel slip represents a challenging problem. The non-optimal wheel slip level during braking, causing inability to achieve the desired tire-road friction force strongly influences the braking distance. In addition, steerability and maneuverability of the vehicle could be disturbed. In this paper, an active neuro-fuzzy approach has been developed for improving the wheel slip control in the longitudinal direction of the commercial vehicle. The dynamic neural network has been used for prediction and an adaptive control of the brake actuation pressure, during each braking cycle, according to the identified maximum adhesion coefficient between the wheel and road surface. The brake actuation pressure was dynamically adjusted on the level that provides the optimal level of the longitudinal wheel slip vs. the brake pressure selected by driver, the current vehicle speed, the brake interface temperature, vehicle load conditions, and the current value of longitudinal wheel slip. Thus the dynamic neural network model operates (learn, generalize and predict) on-line during each braking cycle, fuzzy logic has been integrated with the neural model as a support to the neural controller control actions in the case when prediction error of the dynamic neural model reached the predefined value. The hybrid control approach presented here provided intelligent dynamic model - based control of the brake actuation pressure in order to keep the longitudinal wheel slip on the optimum level during a braking cycle.

AB  - The control of automotive braking systems performance and a wheel slip is a challenging problem due to nonlinear dynamics of a braking process and a tire-road interaction. When the wheel slip is not between the optimal limits during braking, the desired tire-road friction force cannot be achieved, which influences braking distance, the loss in steerability and maneuverability of the vehicle. In this paper, the new approach, based on dynamic neural networks, has been employed for improving of the longitudinal wheel slip control. This approach is based on dynamic adaptation of the brake actuation pressure, during a braking cycle, according to the identified maximum adhesion coefficient between the wheel and road. The brake actuated pressure was adjusted on the level which provides the optimal longitudinal wheel slip versus the brake actuated pressure selected by a driver, the current vehicle speed, load conditions, the brake interface temperature and the current value of the wheel slip. The dynamic neural network has been used for modeling of a nonlinear functional relationship between the brake actuation pressure and the longitudinal wheel slip during a braking cycle. It provided preconditions for control of the brake actuation pressure based on the wheel slip change.

The brake actuated pressure was adjusted on the level which provides the optimal longitudinal wheel slip versus the brake actuated pressure selected by a driver, the current vehicle speed, load conditions, the brake interface temperature and the current value of the wheel slip. The dynamic neural network has been used for modeling of a nonlinear functional relationship between the brake actuation pressure and the longitudinal wheel slip during a braking cycle. It provided preconditions for control of the brake actuation pressure based on the wheel slip change.",

AB  - The basic problem in the operation of automotive brakes is the unpredictable nature of the tribological processes that occur at the contact of the friction pair. The stochastic nature of the tribological contact of the disc brake is affected differently by the complex interaction between the brake disc and the friction material under different conditions because of the influences of the applied pressure, the speed and the brake interface temperature. Owing to the highly dynamic non-linear change in the braking torque induced by the complex situation at the contact of the disc brake, the braking torque could not be modelled, predicted and controlled using classical mathematical methods. This is related, in particular, to the dynamic change in the braking torque in a braking cycle. Dynamic modelling and prediction of the braking torque is very important for further improvement in the performance of the brakes of motor vehicles through more precise control of their performance with respect to the driver demands and the change in the adhesion between the tyre and the road. Recurrent dynamic neural networks were employed in this paper for modelling, prediction and control of the dynamic change in the braking torque during a braking cycle. The dynamic functional relationship between the changes in the applied pressure, the sliding speed, the brake interface temperature and the braking torque of the disc brake was established. The dynamic model developed was used to predict and control the braking torque during a braking cycle under different disc brake operation conditions.

AB  - Computer simulations take an important place in the engineering development of innovative control strategies of vehicle braking systems. The simulations are often used to study and analyze the design and operation of various conceptual solutions of braking systems for determination of a near optimal configurations and performance. In addition, complex and continuously increasing technological demands related to vehicles’ safety and stability issues indicate that design and operation of their braking systems should be constantly improved by developing new and intelligent solutions. Adequate simulation platforms for developing of braking systems with intelligent abilities could be very helpful in analysis of such designed conceptual solutions and verification of the selected control strategies. That is why, a simulation model of intelligent braking system has been proposed in this paper using Matlab/Simulink. It is done in order to simulate the different braking situations and predict the braking system performance versus driver’s demands, vehicle load conditions and actual braking regimes.
