A power VDMOSFET has been simulated using PISCES-II, a 2-D numerical device simulator. The doping densities and device dimensions are chosen so as to simulate a typical device structure with one micron channel length. These simulations are aimed at understanding the device physics through various internal electrical quantities like potential distribution, electric field distribution, and electr...

Silicon-based switching devices have reached the theoretical limitations for high power and high temperature applications whereas silicon carbide (SiC) has emerged as an alternate material system to overcome the limitations and can be used in extreme environment. In this paper, a vertical DIMOS transistor structure, a switching device in 4H-SiC material system, is presented. The model takes int...

This article proposes DisCo , an automatic deep learning compilation module for data-parallel distributed training. Unlike most compilers that focus on training or inference a single device, optimizes DNN model over multiple GPU machines. Existing single-device strategies do not work well in tr...

This report introduces a new sensor network simulator for the Contiki OS the COOJA Simulator. The Contiki OS is a portable operating system designed speci cally for resource limited devices such as sensor nodes. It is built around an eventdriven kernel but supports pre-emptive multithreading at a per-process basis. It also supports a full TCP/IP stack via uIP and the programming abstraction Pro...

The German BSI started a project for an open source eID simulator. It will allow a wide range of personalisation, is more flexible than real cards and is free to use. Background and goals There is a rising need of test cards for developers of eID clients and companies which want to offer services by using the eID function of the German eID card. Today is difficult get test cards for new develop...

CONTEXT Family planning clinic in urban India. OBJECTIVE To assess the usefulness of a pelvic simulator for intimate examination and intrauterine device insertion training, and for enhancing reproductive education for women. DESIGN Observational study using evaluation forms completed by staff, and focus group interviews with women and girls participating in sexual health education. Content ...

OBJECTIVE To examine the importance of platform motion to the transfer of performance in motion simulators. BACKGROUND The importance of platform motion in simulators for pilot training is strongly debated. We hypothesized that the type of motion (e.g., disturbance) contributes significantly to performance differences. METHODS Participants used a joystick to perform a target tracking task i...

Future high performance computing systems may consist of multiple processors and reconfigurable logic coprocessors. As indicated by industry trends, such co-processors will be integrated on existing motherboards without any glue logic. It is likely that such hybrid computing machines will be a breakthrough for various high performance applications. As a result, it has become essential to invest...

BACKGROUND Endovascular surgery benefits patients because of its superior short convalescence and lack of damage to healthy tissue. However, such advantages require the operator to be equipped with dexterous skills for catheter manipulation without resulting in collateral damage. To achieve this goal, a training system is in high demand. METHODS A training system integrating a VR simulator an...

In performance evaluation of Wheel Slide Protection (WSP) systems, adjustment the control algorithm by an on-track test is most important process. However, since it not easy to stably reproduce low adhesion conditions between wheels and rails in tests, must be adjusted under different for each run. Therefore, solve this issue, we have developed a hybrid simulator that combines real-time compute...
