Title: Assessing the impact of workplace design on employee productivity: A Comparative Study of university libraries in China and Pakistan

Abstract:Workplace design is an ever revamping feature in the history of modernization. Moreover, libraries built today must cater the needs of future. Technologically equipped, optimized space utilization and environmental sustainability is the need of the day. This paper is based upon basic methodological factors of workplace design: furniture, noise, light, temperature and spatial arrangement. The study was conducted in 2 countries (Pakistan and China), utilizing the library staff members of universities in respective countries as primary subject population. A questionnaire based subjective assessment for male and female staff was done for both the universities at same point in time. The results show that males prefer noise free workplace while female preference is inclined towards furniture design and comfort. Findings show that both library staff has more concern for noise at workplace. Regardless of the difference of location of both the universities, furniture and temperature show high correlation with employee’s productivity.

Title: Contribution to the Study of surface Waters pollution of Wadi Meboudja (Nord Est of Algeria)

Abstract:Water is the element around which this maintenance of life, an industrial expansion and an alarming growth of water pollution causes enormous difficulties of feeding which obliges us to worry about our health and our living conditions, because their repercussions prove very serious on our environment.\nIn this context, we have tried to give a detailed overview on the pollution of wadi Meboudja (North East of Algeria) by a working protocol based on surface water withdrawals from this oued in order to establish water quality and obtain databases relating to water pollution in Algeria.\nAnd within this framework the analysis of physico-chemical parameters such as : (T°, pH, CE, DO, BOD5, NO3 -, NO2-, Cl-, MES and fatty oils) is necessary in all along the wadi Meboudja (lover, center and downstream), in order to establish a diagnosis of the state of pollution of surface waters of this river.\nThe results obtained show that at the sites where waste water is discharged from the municipality of El Hdjar-Annaba and industrial discharges from the steel processing complex (Arcelormittal), the industrial area of Chaiba and Pont Bouchet, with discharges of agricultural products from the plain of El Hadjar - willaya of Annaba; There is an increase in the levels of nitrates, nitrites and chlorides as well as the potential of hydrogen, electrical conductivity and even the content of suspended matter and fatty oils; and all the latter leads to contamination and increased degrees of pollution of the waters of this wadi which become unusable and which generates an alarming danger by the fact that the latter is located in an urban area, agricultural and surmounting a sub-affleurante groundwater table. Moreover, the water from the wadi flows directly into the Mediterranean Sea through the Seybouse wadi without prior treatment.\nTherefore this situation requires biological, chemical and physical control and treatment in order to be usable by the public.

Title: Investigation of Genetic Variations in Coloured Horses Using Microsatellite Markers

Abstract:The aim of this study was to determine the genetic variation of Coloured horses by using microsatellite markers. In the study, samples from a total of 28 Coloured horse were genotyped using total 17 microsatellite markers, 12 of them are recommended by the International Society for Animal Genetics (ISAG) and the other 5 loci included by the StockMarks Genotyping Kit. A total of 129 different alleles were identified and the average number of alleles was 7.588. The heterozygosity value (Ho) was 0.286 as the lowest (LEX3 marker) and 0.929 (HTG10 marker) as the highest among the markers; the expected lowest heterozygosity value (He) was determined as 0.607 (HTG4 marker) and the highest one was 0.876 (VHL20 marker). The mean Ho and He values were calculated as 0.729 and 0.771, respectively. On a population basis, the mean FIS and FIT values were 0.047. The mean PIC value was 0.741. In the phylogenetic tree formed by the neighbour joining tree (NJT), it was determined that the Coloured horses were generally categorized into 3 groups. Although statistically significant results (P = 0.01008) were found in the studies investigating whether the population of Coloured horses had the risk of extinction or not, it was determined that the data showed normal L distribution indicating no risk of recent extinction. In this study, we determined that the Coloured horses had a genetically important potential.

Title: Modeling and Analysis of D-STATCOM Using Laplace Transform in the dq Frame of References

Abstract:This paper proposes mathematical modeling of D-STATCOM based on Laplace transform technique in which the proposed model is in the complex frequency domain. All state variables in the model are transformed and therefore analyzed in dq reference frame. The proposed model can be linearised and then Laplace transform is applicable to transform the model into the frequency domain. Together with DC-link capacitor voltage control, the proposed D-STATCOM model of reactive power compensation can be evaluated. A simplified 11-kV, 2-bus test power system is employed for simulation. Satisfactory results obtained by simulating the proposed model are compared to those obtained by simulating the switching control of D-STATCOM power circuit created in MATLAB’s Power System Blockset. As a result, the effectiveness of proposed model is verified. It gave satisfactory responses to estimate nonlinear characteristics of the D-STATCOM operation.

Title: A New Autonomous IoT embedded Predictive Control Approach under Imperfect Wireless Networks

Abstract:This paper deals with a real time implementation of an autonomous Internet of Things (IoT) embedded predictive control application for a thermal benchmark system under an imperfect network connection. The control strategy is divided into two cooperative parts under a master-slave architecture, in which two STM32 microcontrollers are investigated. The slave board is closely connected to the process and the master one is a distant controller. The microcontrollers communicate wirelessly via the TCP/IP protocol. In the Master board, a model predictive controller based output-estimator is designed to wirelessly control the benchmark system even where the incoming outputs from the slave board are lost. On the other hand, a buffered structure is implemented in the slave board to compensate the input losses of the arrived control sequences. The proposed Wireless Networked Predictive Control (W-NPC) strategy presents good performances in set-point tracking and perturbation handling in the case of packet dropouts. In addition a comparative study with a Wireless Networked Proportional Integral controller (W-NPI) is presented to demonstrate the effectiveness of the W-NPC strategy.

Title: The harmful effect of electromagnetic radiation from high voltage overhead lines on the human body

Abstract:The interaction analysis between human being and low frequency electric and magnetic field generated by high voltage transmission lines is an important topic for the determination of possible biological effect. A probable risk for leukemia, neuropsychological disorder, cancer, Alzheimer and reproductive outcomes has been reported due to this exposure for peoples living in the vicinity of electrical substations and electrical workers, these risks depend on the intensity, distance and time of exposure.\nIn order to evaluate the induced current in a human body, it is necessary to characterize the spatial distribution of the electric and magnetic field based on the charge simulation method. We also propose a method to reduce the adverse effects caused by these radiated fields by mitigating their intensity. \nThe results obtained by means of computer programs developed by author in MATLAB environment are compared by the limit values given by International Committee on Non-Ionizing Radiation Protection (ICNIRP) for demonstrating the degree of danger due to the induced current and have a certain guidance function for exposed human being to high voltage electrical substations to ensure their safety.

Title: A New Virtual Inputs Approach to Design of a Discrete Internal Model Control

Abstract:This paper provide a comparative analysis of two common control configurations used to control the top and bottom product of binary distillation column. Wood and Berry model has been considered as the model of distillation column and the internal model controller is designed considering a Singular Value Decomposition (SVD) and Virtual Inputs techniques. The first technique can realize the decoupling of under-actuated processes and wipe out unrealizable factors by introducing compensation terms, affecting the dynamic of the system. Moreover, the SVD technique requires the use of a non-diagonal filter, which makes the control system more complex facing of high-dimensional systems. The second technique is used to control in parallel on the modeled process and its model in real time, in case of more manipulated and less number of control variables, which is simple and robust for the construction of the controller. Performance evaluation of two different controllers such as internal model controller (IMC) based on SVD and on Virtual Inputs has been carried out in this paper. Set point regulation and robustness of the controller is evaluated.
