: Autonomous cooperative driving systems require the integration of research activities in the field of embedded systems, robotics, communication, control and artificial intelligence in order to create a secure and intelligent autonomous drivers behaviour patterns in the traffic. Beside autonomous vehicle management, an important research focus is on the cooperation behaviour management. In this paper, we propose hybrid automaton modelling to emulate flexible vehicle Platoon and vehicles cooperation interactions. We introduce novel coding function for Platoon cooperation behaviour profile generation in time, which depends of vehicles number in Platoon and behaviour types. As the behaviour prediction of transportation systems, one of the primarily used methods of artificial intelligence in Intelligent Transport Systems, we propose an approach towards NARX neural network prediction of Platoon cooperation behaviour profile. With incorporation of Platoon manoeuvres dynamic prediction, which is capable of analysing traffic behaviour, this approach would be useful for secure implementation of real autonomous vehicles cooperation.

This paper describes the transient performance and voltage regulation of a stand-alone self-excited induction generator (SEIG). All characteristics are calculated with a ftux-based mathematical model of the induction machine in the stationary reference frame appropriate for the stand-alone SEIG. The generator model and the control system model are developed using Matlab/Simulink. A presented generator model takes into account significant effects of magnetic saturation on the SEIG performance. The simulation was performed by loading the SEIG with a variable resistive load. Some of the computed characteristics are compared with experimental results. Both uncontrolled and controlled response of the SEIG to load variations were analyzed. It is shown that voltage variations can be reduced by using voltage source inverter and terminal voltage controller.

Chemerin is an adipokine associated with parameters of inflammation and the metabolic syndrome. Small observational studies suggested that high circulating chemerin levels are also related to bone erosion. We aimed to determine whether plasma chemerin levels are related to bone quality in the general population and to investigate the influence of body mass index (BMI) on that relation. For our analyses, we obtained data from 3583 adults who participated in the population-based Study of Health in Pomerania-Trend. The participants were divided into three groups according to their BMI: lean (<25 kg/m2), overweight (25 to 30 kg/m2), and obese (≥30 kg/m2). Chemerin concentrations were determined in EDTA plasma. Bone quality was assessed using quantitative ultrasound at the heel. Broadband ultrasound attenuation (BUA), speed of sound (SOS), stiffness index, and osteoporotic fracture risk were derived from this measurement. Sex- and BMI-specific linear regression models revealed inverse associations between chemerin levels and BUA in obese men. In obese women, inverse relations between chemerin levels and SOS or stiffness index were found. Logistic regression models revealed positive associations between chemerin levels and osteoporotic fracture risk. In lean or overweight subjects, no statistically significant associations were found. Our sex- and BMI-specific analyses showed that inverse associations between chemerin levels and bone quality are restricted to obese men and women. The observed association may be due to a chemerin-induced negative affect on bone metabolism, possibly due to abrogation of osteoblastogenesis or stimulation of adipogenesis.

A company follows the concept of corporate social responsibility (CSR) when, in addition to its basic economic functions, it fulfi lls other functions to achieve greater social goals. Corporate social responsibility is an imperative in the modern world of business while in theory, it is still the subject of discussions. Nevertheless, within diff erent theories, there is a certain consensus specifi cally related to the understanding of the importance of stakeholders and the existence of diff erent levels of CSR. Th e main aim of this paper is to explore and analyze employee perceptions of CSR activities in Bosnia and Herzegovina. Th is paper will present a survey of the perception of 100 corporate representatives related to CSR, with an analysis of the infl uence of sociodemographic factors and job characteristics on their attitudes. In addition, the paper off ers the conclusion, with a number of recommendations for improving the current state of CSR in Bosnia and Herzegovina.

Objective: The aim of this study was to evaluate corelation of serum level of NGAL to severity of hypertension and diastolic disfunction in patients with ST- segment elevation myocardial infarction treated with fibrinolytic therapy. Design and method: We included 54 consecutive ST-segment elevation myocardial infarction patients treated with fibrinolytic therapy (alteplase). The median follow-up time was 6 days (interquartile range, 5 to 7 days). Blood samples were drawn immediately after admission prior to fibrinolytic administration. The endpoints were mean systolic and diastolic pressure (continuously monitored) and mean E/A ratio as a measure of diastolic function. Results: Patients with high NGAL (above 134,05 &mgr;g/l; 75th percentile) had significantly higher mean systolic and mean diastolic blood pressure compared to patients with low NGAL (under 134,05 &mgr;g/l; 75th percentile), p = 0,001 and p = 0,003; respectively. Patients with high NGAL (above 134,05 &mgr;g/l; 75th percentile) had significantly lower E/A ratio compared to patients with low NGAL (under 134,05 &mgr;g/l; 75th percentile), p = 0,004. Conclusions: High NGAL significantly corelates with severity of hypertension and diastolic dysfunction in patients with acute STEMI.

Nanotechnology has shown its great potential in different fields of science such as medicine and pharmacy. This paper presents a review on artificial neural networks used in nanotechnology based on information gathered from different research. It is important to understand applications of artificial neural networks so that they can be used even more efficiently in future applications. Research papers summarized and compared here show different results in two fields of science. Artificial neural networks were made and proven to be useful in diagnostics and tracing diseases. The pharmaceutical industry has also shown to be a good candidate for the development of ANNs on the nanotechnology level. Regression analysis was used as a statistical method for presenting the best results from both fields observed. Root mean square error and mean error were calculated to measure the differences between values predicted by a model and the values actually observed from the environment that was being modelled. Based on individual results, each of the ANNs made were accurate enough to be considered as a diagnostic tool in fields of medicine and pharmacy. Performance is greater than 90% 10 out of 12 times, which is viewed in this paper. The multilayer perceptron ANN is mostly used. Based on the latest results, in upcoming years, one can expect better understanding and more research in the field of ANN applications in nanotechnology.

This paper presents an overview of a study in which the immunity and susceptibility of life-supporting medical equipment was evaluated by exposing the equipment to electromagnetic interference (EMI). Electromagnetic interference, in the past, has been proven to influence the activity and reliability of certain medical devices. Since there has been dramatic increase in the use of cellular phones, these electromagnetic emitting devices have become part of the environment of medical devices. In the present paper, the influence of cellular phones at various distances and proportions on a wide range of medical devices were studied. In total 136 devices were tested after being exposed to cellular phones working in different operating modes. Testing was performed in Healthcare institutions of Bosnia and Herzegovina. Out of all 136 devices, a significant interference was detected in only one of the various defibrillators tested. Other EMI encountered in two electrocardiograms, during the tests, were negligible which proves that current medical devices are designed to operate more safely, with higher immunity and lower susceptibility. The improved designs of medical devices are results of strict electromagnetic compatibility standards to which the devices must comply.

Abstract This paper uses a DEA-VRS methodology for the estimation of municipal efficiency to provide empirical evidence of the impact of decentralization in BiH under the Dayton Peace Agreement (DPA) on overall municipal efficiency. In particular, the paper focuses on the analysis of the overall efficiency of 33 new municipalities established under DPA. The findings suggest that the average municipal efficiency in BiH is rather low, and only 23 or 16% of municipalities in BiH are efficient. The average efficiency achieved is around 0.71. This means that with the same level of inputs (budget revenue) outputs may be increased by almost 30%, on average. The results of DEA-VRS efficiency estimation suggest that new municipalities have lower average efficiency (0.60) in comparison to “older” municipalities (0.74). In our sample, only six percent of newly created municipalities are efficient, 12% exhibit some level of efficiency, while the remaining 82% are inefficient, with significant share (39%) of very inefficient municipalities

We address a cooling energy management problem in a multi-building setting where buildings need to maintain comfort conditions for the occupants by keeping their zones temperature within a certain range. To this purpose, each one of them has its own chiller and is connected to a shared cooling network. The goal is to minimize the overall district electricity cost over some finite time horizon by optimally setting the temperature set-points in the buildings and the energy exchange with the cooling network, compatibly with comfort and actuation constraints, while accounting for uncertainty, mainly due to outside temperature, people occupancy, and solar radiation. To this purpose, a distributed version of the scenario approach to stochastic constrained optimization is adopted, which allows to guarantee by design a predefined robustness level of the obtained solution against uncertainty.

Introduction: Neuropathic pain resulting from injury to the nervous system. Up to 7% to 8% of the European population is affected. A number of different treatments for neuropathic pain have been studied including antiepileptic. Pregabalin and gabapentin are often considered first-line treatments. Pregabalin provides equivalent efficacy to gabapentin, showing greater potency at much lower doses and is considered as cost-effective intervention. In Federation of Bosnia and Herzegovina (FB&H), gabapentin is fully reimbursed, while pregabalin is enlisted on list B with copayment. Aim: To develop simple budget impact (BI) model and assess BI of introducing pregabalin into full reimbursement in FB&H. Material and methods: Budget impact model was developed using Microsoft Excel 2010. Local epidemiology data and data on drug consumption from government reports in 2016 were used. Two scenarios with three-year time horizon have been developed: 1) without and 2) with pregabalin reimbursed at the same level as gabapentin. Two developed scenarios have been compared from health insurance fund (HIF) perspective. Results: In scenario 1 consider both drugs fully reimbursement and without patient switch among alternatives the total cost would be increased for 780,025 KM; 852,027 KM and 943,830 KM over a 3-year period. In scenario 2 considering both drugs fully reimbursed but with patient switch topregabalin total annual cost would be increased for 732,241 KM; 742,395 KM and 751,761 KM. Comparing scenario 1 and 2 it is found that scenario 2 is more favorable from HIF perspective. Conclusion: Implementation of pharmacoeconomic principles in reimbursement decisions in Bosnia and Herzegovina would improve access to medicines and contribute rationale resource consumption.

Aim To compare individual case safety reports (ICSR) rates and characteristics between Croatia, Serbia, Montenegro, and Bosnia and Herzegovina (B&H). Methods This retrospective pharmacoepidemiological study used the data from ICSR received by the Agency for Medicines and Medical Devices in B&H in 2011-2016. The number, characteristics, and sources of reports, suspected drugs, and patient characteristics were analyzed. The results were compared with the publicly available data from Croatia, Serbia, and Montenegro. Results The number of reported adverse drug reactions per one million of inhabitants was lowest in B&H and highest in Croatia. There were significant differences in reporter characteristics, sources of reports, and the percentage of missing data in ICSR, while the Anatomical Therapeutic Chemical product classes, patient’s sex, and adverse drug reaction System Organ Classes were similar. Conclusion Despite the historical and geographical vicinity of B&H and its neighboring countries, there were significant differences in indicators of pharmacovigilance development.

Phasor estimation is an essential task in power system since the voltage angle and voltage RMS determine the available active power and its flow. This paper proposes fast and simple algorithm for harmonic phasor estimation in a three-phase system. Harmonics are considered the most serious power quality (PQ) problem in the emerging scenario with a growing proportion of power electronic based devices in the power system. The algorithm is based on well-known mathematical transform and recommendations given in relevant IEC and IEEE standards. The presented algorithm can be used to generate input data for Harmonic State Estimation.

The paper describes a photovoltaic system (PVS) composed of a group of photovoltaic (PV) panels and presents the initial evaluation of power quality (PQ) in the low-power microgrid connected to these PV panels. This PVS is called solar tree and it is built as a research platform at our faculty to conduct teaching and research on renewable energy sources. The solar tree can operate in two modes: on-grid and off-grid (autonomous operation). An off-grid mode was analysed and experiments were carried out in order to determine the maximum power that can be delivered to the load connected to this autonomous photovoltaic system (APVS). Also, the various consumer's responses to a sudden load changes in this APVS were analysed. The experiments were carried out by using modern power quality monitoring devices and PQ of this single-phase APVS with energy storage is examined in terms of compatibility with the relevant international standards.

The effect of the aqueous extract of Achillea millefolium L . (AM) on the electrochemical behaviour of iron in a simulated acid rain solution (pH 4.5) was studied by electrochemical techniques cyclic voltammetry, potentiodynamic polarization and electrochemical impedance spectroscopy. Experiments were carried out over a wide range of AM concentrations. The results of all techniques showed that AM extract contributes to iron passivation. The films formed in the presence of AM extract were thinner and more resistive then the films formed in pure simulated acid rain solution. The AM extract adsorbed on the iron according to the Freundlich isotherm. The thermodynamic data indicated physical adsorption of the AM extracts on the iron surface. The concentration of the metallic ions released into solution, measured by atomic absorption spectroscopy, was in accordance with the results obtained from the electrochemical techniques.
