Nonlinear optical processes are one of the most important tools in modern optics with a broad spectrum of applications in, for example, frequency conversion, spectroscopy, signal processing and quantum optics. For practical and ultimately widespread implementation, on-chip devices compatible with electronic integrated circuit technology offer great advantages in terms of low cost, small footpri...

background: venoarterial extracorporeal membrane oxygenation (ecmo) provides systemic arterial support without directly unloading the left heart, which causes an elevated left ventricular (lv) pressure. the aim of the present study was to investigate the adjunctive application of the impella device for lv unloading in patients during ecmo. methods: this retrospective cohort study included patie...

this study aims to examine how iranian efl learners perceive and apply mitigation devices in request speech act in 4 asymmetrical situations. role-play interactions and questionnaires were used to elicit the required data from iranian informants (male vs. female). the results obtained from the analysis of data revealed that in identical situations, male requestors were comparably more certain t...

Image denoising is the fascinating research area among researchers due to applications of the images in everywhere, social networking sites, High Definition videos and stills. The need of it is to enhance the facility to imaging devices and the processing devices for denoising and enhancement of images. In this paper, Total Variation (TV) regularization is used to allow for accurate registratio...

We present a homotopy continuation method (HCM) for finding multiple operating points of nonlinear circuits composed of devices modelled by using piecewise linear (PWL) representations. We propose an adaptation of the modified spheres path tracking algorithm to trace the homotopy trajectories of PWL circuits. In order to assess the benefits of this proposal, four nonlinear circuits composed of ...

Use of interaction devices on human-computer system may cause muscolusceletal disorders. This paper presents an Electromyography study to evaluate the hand muscle activities when it is interacted with the computer using mouse, keyboard and joystick. These muscles investigated are flexor pollicis brevis, flexor digitorium superficiallis and abductor pollicis brevis. Average of Root Mean Square (...

Parametric studies of the effects of slip irreversibility in concentrating solar power (CSP)-powered bio-digester assemblies are investigated. Complexities regarding the identification of the appropriate electro-kinetic phenomena for certain electrolyte phases are reviewed. The application of exergy analysis to the design of energy conversion devices, like solar thermal collectors, for the requ...

INTRODUCTION The state of understanding of the destructive SEGR event in power MOSFETS is relatively mature with large published efRorts, both experimental [1-5] and theoretical [6-8]. However, gaps remain in the understanding of the phenomenon, including unexplained experimental anomalies, empirical-only dependencies on some important device and incident ion physical parameters, and limited in...

To increase the throughput of electronic manufacturing companies, design, prototyping, production, installation and maintenance processes of electronic devices are generally complemented by a number of performance and parametric tests, known as Failure Analysis (FA). In this paper, major FA proposals are considered. In particular, two noninvasive solutions are presented in detail: an advanced b...

The impacts of building envelope designs are significant on indoor thermal environment, especially for naturally ventilated buildings. Parametric façade studies were investigated for various orientations, window sizes and shading devices by using building simulation (ESP-r) and CFD (FLUENT) coupling program to predict indoor thermal environment in an accurate and quick way. Two typical weeks we...
