Should MNCs adopt the regulations in the country of origin or yield to hose in the country of operation?[ ]


Multinational organizations are the elements who specifically work and utilize employees in various nations. In perspective of the way that MNC's are not straightforwardly operational inside of their nation of origin, excluding (host country) components ought to also be acknowledged. The main effect is the country of origin sway or now and again called home-country sways. The country-of-origin impact can be delineated utilizing social and institutional procedures. Social techniques rely on upon the norms, qualities and demeanors of a nation. Hofstede proposed a framework known as measurements of national societies. The more unmistakable the social refinement in the middle of home and the host nation, the extreme it will be for the MNCs to switch home-country strategies for understanding. Despite the way that Hofstede and his social estimations show contrasts between nations, it doesn't independently clear up nation of-birthplace effect.

The Effect of Etching Current Density on Porous Silicon Fabricated by Electrochemical Etching Process[ ]


Porous silicon (PS) was fabricated using p-type Si with <111> orientation by electrochemical etching process (ECE) at a constant etching time of 20min and different current density of 10-40mA/cm2. The surface morphology of PS studied by atomic force microscope (AFM) verifies that average diameter and nanostructure are dependent on the etching current density, when the current density increased from 10 to 40mA/cm2 the average diameter also increased from 29.96 to 45.59nm. The FE-SEM image of the sample prepared at 20min and 10mA/cm2 shows a homogeneous pattern and confirms the formation of uniform porous structures on the silicon wafer. From XRD pattern, the peak intensity decreased and full-width half maximum (FWHM) increased with increasing current density from 10 to 40 mA/cm2 and the crystalline size also decreased from 10.8 to 2.5nm. From FTIR spectra of PS at different etching current range from 10 to 40 mA/cm2, it was found that the transmittance peaks around 997.13 cm-1 and 1097.42 cm-1 are from Si–O–Si asymmetric stretching modes, which are dependent on the oxidation degree of PS. The transmittance peaks at 624.94-630.68 cm-1 Si-H wagging mode bending in (Si3-SiH), and 810.05-813.90 cm-1 from Si-F stretching mode. Photoluminescence spectra (PL) showed that the band gap energy increased from 1.610 to 1.638eV when the current density increased from 10 to 40mA/cm2.

Effects of Heat Transfer of Viscous Incompressible Dusty Fluid[ ]


If the lines of motion are parallel to a fixed plane and if the velocity at corresponding points of all planes has the same magnitude and direction the motion is two dimensional and w=0. The present problem is concerned with heat and mass transfer in free convective flow of a visco elastic dusty gas through a porous medium induced by the motion of a semi-infinite flat plate moving with velocity decreasing exponentially with time heat source parameter. It is clear that the existence of a stream function is a consequence of stream lines and equation of continuity for incompressible fluid. The expression for velocity distribution of dusty fluid, dust particle, temperature and concentration distribution are obtained. Source is a point at which liquid is continuously created and sink is a point at which liquid is continuously annihilated.

Grid Side Converter Controller Optimized for DFIG Driven Wind Turbine Based on Type-2 Fuzzy Logic[ ]


Grid side system GSS model is studied and developed in steady state form by using phasor theory; studying the relationships between active and reactive powers, voltage, and currents at different operating modes. Then, control of the grid side converter GSC is optimized; developing the grid side dynamic model based on space vector theory. In this paper vector control technique that utilizes a rotating reference frame (dq) aligned to the grid voltage space vector is employed. This control algorithm made it possible to achieve the two main objectives of GSC: control of the DC bus voltage and assure transmission of power through the converter (along with controlled reactive power exchange). DC link bus voltage has been controlled using Interval Type-2 Fuzzy Logic Controllers (IT2FLCs). The proposed IT2FLCs were designed to deal with the ambiguity appeard as a result of changes during system operation. In this paper, design of GSC controller, which is responsible for the terminal voltage control in addition to the DC link voltage regulation, is performed. The developed IT2FLC controller is simulated using MATLAB/SIMULINK software for a 1.5 MW typical wind turbine to verify the performance of the controller.

Genetic Algorithms Based Orientation and Scale Invariant Localization of Vehicle Plate Number[ ]


In this research, an enhancement of a previously designed genetic algorithm is introduced to detect the locations of the License Plate (LP) symbols at any in-plane rotation angle. Consequently, the unify-sort-partition-sort (USPS) crossover operator and the objective distance definition introduced in the original system are generalized to support rotation invariability. In addition, a more efficient implementation is introduced in the design of the chromosome layout and the geometric relationship matrix (GRM) to support fast evaluations and convergence in case of inclined plates and missed symbols. A verification stage has been added to filter out false positives and minimize false negatives. Encouraging results with average accuracy above 98% have been reported for a large dataset of 1500 LP samples having variability in orientation, scaling, plate location, illumination and complex background. Examples of highly inclined LP images were successfully detected proving the ability to detect LPs in emergent conditions such as accidents and crime circumstances.

Optimal Maximum Power Point Tracking of PV Systems based Genetic-ANFIS Hybrid Algorithm[ ]


The maximum power point tracking (MPPT) technique in the photovoltaic (PV) system is used to achieve maximum power from the solar PV system. In this context, three MPPT techniques, artificial neural network (ANN), fuzzy logic control (FLC) and adaptive neuro-fuzzy inference system (ANFIS), are implemented and their performance is investigated in terms of efficiency and response. And they are developed in MATLAB/Simulink environment. This system is developed by combining the models of established solar module and DC-DC boost converter with the genetic algorithm for the three techniques. So this paper presents a new approach based on the genetic algorithm used to perform a constrained tuning technique for the PID parameters to optimize the power output of solar panel. The dynamic model is used to design the controller parameters of the conventional PID controller. The dynamics of the DC-DC converter is non linear. Therefore, it is hard to derive desirable performance. Hence, Genetic algorithm is used to optimize the control parameters of the boost converter. In order to obtain the fitness of an individual, Simulink model of the boost converter is designed and the genetic algorithm is programmed to search for the optimal control parameters by the MATLAB built ingatool. The system is simulated under different climate conditions and MPPT algorithms. According to the comparisons of the simulation results, it can be observed that the photovoltaic simulation system can track the maximum power accurately using the three MPPT algorithms discussed. Therefore, the interest is generated to design a more effective and efficient MPPT to achieve maximum power transfer to the load.
