In this paper, we deal with the control of motor pumping system. For that, cascade sliding mode control structure is proposed. It gives interesting features in terms of stability, robustness against parameters variation, and tracking performance. The induction motor pumping system is fed by a PV solar panel. In order to obtain an optimized maximum power from the PV source, we have used an effective fuzzy MPPT approach. The proposed algorithm can guarantee the maximum power whatever illumination or temperature level variation. Simulation of the proposed structure is validated under Matlab/Simulink. Obtained results show a perfect tracking performance under an optimal photovoltaic power.

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.

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.

Recently, in many industrial processes research has picked up a fervent place and a particular importance in the area of fault diagnosis of electrical machines, in fact, a fault prognosis has become almost indispensable. The need of a mathematical model of three-phase induction machine, suitable for the simulation of machines behaviour under fault conditions, has received considerable attention. This paper addresses an accurate model for three-phase squirrel cage induction motors, based on coupled magnetic circuit theory, capable to take into account any conditions of the machine like stator and/or rotor faulty conditions. The exactitude of the model is due to the use of the real geometry of the machine together with the physical layout of all windings. Moreover, the detailed depiction of the machine permits to determine new accurate formulas of inductances, such as, the self-inductances of the rotor loops, stator coils, as well as the mutual inductances between the stator coils and rotor loops. To demonstrate the effectiveness of the model, the case of broken rotor bars as a source of rotor electrical asymmetry was studied. Experimental results show that the proposed model predicts the induction machine behaviour with a good accuracy.

This paper examines the practical application of Model Predictive Control (MPC) algorithm for vibrating feeder with an electromagnetic actuator. In the base of this practical application are two microcontrollers STM32F407, one for digital data acquisition and implementation of the signal envelope detection and the other for implementation of the controller algorithms. Linearization of the well-known nonlinear system model and discretization of adopted linear system model has been performed. The linearized model has been experimentally verified. It has been proposed an algorithm for the envelope detection of the trough movement signal. This algorithm is made for concrete application in vibratory feeders, but its principle of operation is practically applicable for all the low dynamic processes. A comparison has been made for the obtained experimental results of the system with the feedback for the MPC and the PI controller. The frequency characteristics of the system with feedback have been recorded and its stability has been confirmed.

Background: Asthma and Type 1 diabetes (T1D) are chronic inflammatory diseases where Th2 and Th1 cells play important roles. Treg and Th17 cells play role in development of both diseases. \nAim: NK cells are divided in NK1 and NK2 cells similar to Th cells. IL-10 and IL-17 do also play role in many diseases. We aimed to show role of NK cytokines in pathogenesis of both diseases.\nMaterials and Methods: Isolated NKs of subjects with T1D (n:3), allergic asthma (n:4) and controls (n:3) were cultured with IL-2, IL-15, IL-2+IL-15 and without stimulation for 1 to 5 days. IFN-? was determined by ELISA; IL-4, IL-10 and IL-17 by Multiplex bead immunoassay. \nResults: IL-4 in T1D after 24 hours decreased compared to controls. Similar decrease was observed after 5 days in unstimulated and IL-15 conditions. IL-10 was lower in asthmatics compared to controls by IL-15 after 24 hours. IL-10 increased in controls by IL-2 after 5 days compared to T1D. IL-17 decreased without stimulation after 24 hours in T1D compared to controls. IFN-? in T1D increased at both periods under IL-15 and IL-2+IL-15 stimulations compared to other groups. \nConclusion: NK cells in asthma and T1D show cytokine profiles similar to T lymhocytes.

Node identity theft in a Wireless Sensor Network (WSN) is a vital issue in security, which can\nbe misused by attackers to gain control of network resources as they can pretend to be a legitimate node. This\nissue becomes more challenging when it comes to clustered WSN which is more threatened by eavesdropping\nand impersonation due to centralized controlling by cluster head and shared wireless medium. Therefore,\ncurrent research is based on designing an intelligent routing strategy to provide secure communication in a\ncluster of sensors. In this context, initially a robust cluster head selection model is designed and thereafter a\nmultistage authentication algorithm is built based on sensor energy, position, network reputation and other\nparameters. Eventually, the proposed intelligent routing protocol establishes the authenticity of any sensor\nparticipating in network communication within WSN, minimizing the probability of various security\nbreaches by malicious attacker. From the experimental analysis, it is found that better results are achieved\nfrom the proposed system.

Flexible alternating current transmission system (FACTS) play an important role in electrical power transmission systems by improving power quality and increasing power transmission capacity. The STATCOM (STATic COMpensator) is a member of the FACTS devices. Which is a power-electronics-based regulating device composed of a voltage source converter (VSC) and is shunt connected to alternating current transmission and distribution networks.\nThis paper describes the modeling and analysis of a two-level synchronous static compensator (STATCOM) for reactive power compensation using Hysteresis Current Controller (HCC) and compares its performance with that of the PI controlled space vector pulse width modulation (SVPWM) method. The system has been simulated using the Matlab Simulink. Various simulation results are presented and performance of the two control techniques is compared.

Cytochrome P450 (CYPs) constitutes the major enzymes that can detoxification of most drugs into less products. The current work was designed to investigate the possible ameliorator effect of aminoguanidine (AG) on cytochrome P450 forms in livers of acute or chronic γ-irradiated rats. Thirty male rats were divided into six groups of five rats each. Groups were located as normal control (non-treated), positive control (rats injected i.p with 400mg AG/kg/day for one month), acute γ-irradiated rats group (rats exposed to a single dose (6Gy) of whole body gamma rays and left without treatment), acute γ-irradiated + aminoguanidine rats group (rats exposed to 6Gy gamma rays as chronic dose and treated with 400mg AG/kg/day for one month), chronic γ-irradiated rats group (rats exposed to 2Gy/week for three successive weeks) and acute γ-irradiated + aminoguanidine rats group (rats exposed to 6Gy gamma rays as acute dose and treated with 400mg AG/kg/day for one month). The results showed that aminoguanidine supplementation to acute or chronic irradiated rats regulated the activity of hepatic cytochrome P450 forms (cytochrome b5 reductase, cytochrome c reductase, cytochrome P450 reductase as well as CYP1A1, CYP1A2 and CYP2B1) associated with reduction in the content of liver cytochrome P450. These data can be concluded that aminoguanidine has a multifunctional property which acts as antioxidant and radio-therapeutic agent.

In this study, we propose the improved form of B. K. Singh, Choudhury, and Kalita (2013) by using log function in exponential ratio estimator to estimate the mean of the study variable Y under two phase sampling by incorporating two auxiliary variables. The performance of suggested estimator is compared with other ratio type estimators and also studied the properties of proposed estimator. It is observed that ratio and exponential ratio estimators considered by several well known researchers and usual unbiased estimator is less efficient than our proposed estimator. The expression for mean square error and mathematical comparisons are also presented. Theoretical analysis is performed for checking the merits of our proposed estimator and outcomes are sound and moderately illuminating in comparison to different estimators.

The developments in telecommunication networks have proved that the number of hardware in access networks is reduced by using the optical transmission technology. Higher order modulation formats such as 4 level pulse Amplitude Modulation (PAM4), Digital Signal Processing (DSP) techniques and Short Wavelength Division Multiplexing (SWDM) with wideband Multimode Fiber (MMF) have been proposed to increase the capacity over the data centre networks. The optical power has been increased to reduce the channel loss and attenuation. BER (Bit Error Rate) is significantly improved by choosing strong signal strength, and efficient modulation schemes. The paper also analyzes how optical transmission technology improves the computing power in the network of computers
