A. Krishnan, S. Thangaprakash,

New control circuits and algorithms are frequently proposed to control the impedance (Z) source inverter in efficient way with added benefits. As a result, several modified control techniques have been proposed in recent years. Although these techniques are clearly superior to the simple boost control method which was initially proposed along with the Z-source inverter (ZSI), little or conf...

Green’s function, an analytical approach in inhomogeneous linear differential equations, is the impulse response, which is applied for deriving the wave equation solution in composite materials mediums. This paper investigates the study of SH wave’s transmission influenced by concentrated point source disturbance in piezomagnetic material resting over heterogeneous half-space. Green function ap...

Background and aims: Heat stress is one of the most important occupational hazards that threaten the health of employees in many workplaces. This hazard is more important in the industries with hot processes, such as rubber industry. Therefore, control of this harmful agent is one of the essential measures and priorities of manager in these industries. The purpose of this study was to identifyi...

Silicon is one of the beneficial elements for plants, recent studies have shown that this element plays a very important role in plant resistance to environmental stresses, including heavy metal stress. To evaluate the effect of silicon foliar spraying on increasing tolerance to lead contamination in dill (Anethum graveolens L) a factorial experiment based on completely randomized design with f...

The three-phase-lag model and Green–Naghdi theory without energy dissipation are employed to study the deformation of a two-temperature fiber-reinforced medium with an internal heat source that is moving with a constant speed under a hydrostatic initial stress and the gravity field.  The modulus of the elasticity is given as a linear function of the reference temperature. The exact expressions ...

The thinking and the practice of managing resistance to change is usually associated with change recipient’s psychological set up. In most cases, employees are either implicitly or explicitly considered as the prime source of resistance. Exploring the initiation and implementation of organizational change in Ethiopian commercial banks, this research found out that resistance to change does not ...

Finite element method (FEM) is one of the most famous methods which has many applications in varies studies such as the study of crack propagation in engineering structures. However, unless extremely fine meshes are employed, problem arises in accurately modelling the singular stress field in the singular element area around the crack tip. In the present study, the crack growth simulation has b...

Introduction. The once popular idea that changes in planetary volume play an important role in terrestrial orogeny and tectonics [ I ,2] was generally discarded with the acceptance of plate tectonics. It is nonetheless likely that the Earth has been steadily cooling over the last 3-4 billion years [e.g., 3,4], and the global contraction that accompanied such cooling would have led to a secular ...
