Area 1 includes thermal system, Distributed Generation (DG), and aggregate Electric Vehicle (EV) wheras area 2 contains thermal system, gas system, and aggregate electric vehicle. Nonlinearities such as Generation Rate Constraint (GRC), Governor Dead Band (GDB), Boiler Dynamics (BD), and Communication Delay (CD) are explored in the proposed test system to achieve a realistic approach. For considering cross coupling effect between excitation system and AGC, an exact model has been investigated. A novel cascade controller has been proposed to achieve the desired goal. For optimum values of controller, new novel Quasi Opposition Lion Optimization Algorithm (QOLOA) has been suggested and implemented for the studied system. The sensitivity analysis study was performed to assess the robustness of the proposed controller by varying system parameters. System parameters are varied by ±25%, ±35%, and ±50%, and the result shows the robustness of the controller and algorithm For the proposed controller, Figure of Demerit (FOD) is compared with various algorithms, and the Integral square Error (ISE) is taken as objective function. The optimistic results shows the effectiveness & superiority of proposed AGC in different scenario of deregulation.

Solar PV module is exposed to external environments where dust deposits are a major derogatory factor. The soil and its effect on the performance of the solar module is usually a matter of high concern for the areas of high density and high frequency of low frequency and low-intensity rainfall. Due to the PV module, the effects of dust are examined in relation to various types of dust concentration and spectral transmission. For examination and analysis, experimental investigation is reported in the paper. The investigation shows that dust effects are accumulated, i.e., the performance of the PV module decreases over time with increasing statements, or until it is cleaned manually or through rain. It is also observed that the inclination of the PV installation plays a major role in the quantity of dust deposited on the angle equipment, where the concentration of dust is reduced as a result of higher tilt angles. Aligarh, with its irregular environmental conditions, suffers from high air pollution and minimum rainfall during dry winter. In this study, the impact of dust on the PV module is examined in relation to the dust density of the dust and the meteorological variables for Aligarh, with the purpose to calculate the drop equation describing efficiency loss.

In this research, the thermal conductivity of maghemite (MH) nanoparticles dispersed deionized water (DW) nanofluids (MH/DW) has been evaluated for the first time using the modified effective medium theories (EMTs). EMTs have been modified with the consideration of static and dynamic effects combinedly for the analysis of anomalous behaviors of thermal conductivity enhancements of the spherical nanoparticles dispersed nanofluids. MH nanoparticles (~20 nm) were synthesized using chemical co-precipitation techniques. MH/DW nanofluids were prepared with the varying MH nanoparticles loading in DW and thermal conductivity was measured using KD2 pro device. The thermal conductivity enhancement (~32 %) was found to be increased linearly with the increasing MH nanoparticle concentration and nonlinearly with the increasing temperature. Existing Maxwell and Maxwell Gantt EMA (MG-EMA) models exhibited awful under-prediction from experimental thermal conductivities of MH/DW nanofluids. Modified model with considering static and dynamic mechanisms of MH nanoparticles combinedly showed reasonably very good agreement with the experimental thermal conductivities of MH/DW nanofluids at elevated temperature. This modified model opens the new windows to analyze the insight of the thermophysical properties of various types of nanofluids by introducing potential parameters.

In this study, laboratory experiments were conducted to investigate the effectiveness of downstream bed sill location as countermeasure method to decrease the local scour under clear water conditions for single cylindrical pier. Four flow intensities were tested (from 0.48 to 0.96 of the threshold velocity of sediment) with five different bed sill locations (from 0 to 4 pier diameter). The measured scour depths were compared with that observed at the exposed pier (four tests for unprotected pier) to estimate the percentage reduction in scour depth for each flow intensity and to assess the aspects of bed sill location. The results revealed a significant effect of bed sill location on decreasing the scour depth with in downstream distance equal to pier diameter. Accordingly, the percentage decrease in scour depth was ranged from 4 to 30%. New empirical formula has been proposed to estimate scour depth near circular bridge piers according to different bed sill configuration.

In the present study, the quality of the agricultural drainage water of the Al-Husseiniya irrigation project of Karbala governorate in Iraq is assessed and managed in order to reuse this water for irrigation. The Brazilian Water Quality Index (IWQI) model is used to evaluate the quality of the drainage water and the river water within the study area. As well, the quality of drainage water of six selected stations is improved by blending this water with the river water by using nine blending ratios. It is found that 75% of the values of the IWQI classification category of the drainage water are within the category of severe restriction, SR, and 25% of these values are within the category of high restriction, HR.

How to move effectively becomes crucial when a navigation skill must be practiced by a mobile robot soccer in a dynamic environment with high speed. This paper proposes the use of the Fuzzy-based Social Force Model (F-SFM) to control the navigation of a soccer robot. In the framework of the Social Force Model (SFM), the speed and direction of navigation are determined by the resultant force calculating from the attractive force by the goal and the repulsive force by obstacles. The amount of repulsive force generated by each obstacle is largely determined by the stimulus received by the robot and the pre-defined SFM parameters setting. Here, the Fuzzy Inference System (FIS) is used to adapt to one SFM parameter, i.e., gain factor, , based on the stimulus received, namely the relative distance of the obstacle, , and its direction, . With the ability of parameter to change adaptively, the reactivity and responsiveness of the robot can be controlled.
