in order to develop more efficient engines, it is essential to optimize the lubrication circuit of the power train systems. in this paper, during an engine design and development process, a network analysis of the engine lubrication system is described in detail. two elements have been added to the lubrication circuit in the modified engine. these elements are hydraulic lifters and an anti-drai...

This paper presents and discusses two possible real-time digital predistortion (DPD) architectures suitable for envelope tracking (ET) power amplifiers (PAs) oriented at a final computationally efficient implementation in a field programmable gate array (FPGA) device. In ET systems, by using a shaping function is possible to modulate the supply voltage according to different criteria. One possi...

A dual-halo dual-dielectric triple-material cylindrical-gate-all-around/surrounding gate (DH-DD-TM-CGAA/SG) MOSFET has been proposed and an analytical model for the transconductance-to-drain current ratio (TDCR) has been developed. It is verified that incorporation of dual-halo with dual-dielectric and triple-material results in enhancing the device performance in terms of improved TDCR. The ef...

INTRODUCTION Though surgical drainage is used as a safety measure, it's not without complications. Migration of various drains has been described, but very little literature refers to the migration of peritoneal drain. PRESENTATION OF CASE A 55-year male underwent anterior Gastro-Jejunostomy for inoperable metastatic carcinoma of the Gastric Pylorus. We found the peritoneal drain missing on t...

Increased expression of vascular endothelial growth factor (VEGF) has been associated with increased lymph node metastases. The aim of this work was to determine whether VEGF-induced hyperpermeability affects peritumor interstitial convection and lymphatic drain, thus linking this growth factor with lymphatic function. Noninvasive imaging of lymphatic function induced by vascular hyperpermeabil...

In this paper, an analytical modeling is presentated to describe the channel noise in GME SGT/CGT MOSFET, based on explicit functions of MOSFETs geometry and biasing conditions for all channel length down to deep submicron and is verified with the experimental data. Results shows the impact of various parameters such as gate bias, drain bias, channel length ,device diameter and gate material wo...

In this paper the features of multiple material gate silicon-on-insulator MOSFETs are presented and compared with single material gate silicon-on-insulator MOSFET structures. The results indicate that the multiple material gate structures reduce short channel effects such as drain induce barrier lowering, hot electron effect and better current characteristics in comparison with single material ...

In this paper we present current voltage and trans-conductance model for Dual Material Gate AlGaN/GaN HEMT. Our proposed model demonstrates complete charge control in 2DEG based channel of the device in order to investigate the current-voltage as well as transfer characteristics of the device under various gate and drain biases. The proposed device structure uses GaN material capable to withsta...
