Silver sintering joints and AuGe soldering are promising technologies for high temperature (>200 C ambient) power electronics packaging. This paper presents the implementation of two silver-sintering processes with the one hand micrometer-scale silver particles, and on the other hand nano-meter-scale particles. Two substrates technologies have been investigated: A12O3 DBC and Si3N4 AMB. After t...

A compact, real-time PCR instrument was developed for rapid, multiplex analysis of nucleic acids in an inexpensive, portable format. The instrument consists of a notebook computer, two reaction modules with integrated optics for four-color fluorescence detection, batteries, and a battery-charging system. The instrument weighs 3.3 kg, measures 26 x 22 x 7.5 cm, and can run continuously on the in...

While invoicing currency has been extensively studied in open-economy macroeconomics, Dotsey and Duarte (2011) suggest that the currency denomination of exports does not matter because standard invoicing currency regimes such as producer currency pricing (PCP) and local currency pricing (LCP) generate similar aggregate responses. However, this paper demonstrates the importance of invoicing curr...

ZJUNlict have participated in Robocup for about nine years since 2004. In this paper, we summarizes the details of ZJUNlict robot soccer system we have made in recent years. we will emphasize the main ideas of designing in the robots’ hardware and our new software systems. Also we will share our tips on some special problems.

Sensor networks have emerged as an interesting and important research area in the last few years. These networks require that time be synchronized more precisely than in traditional Internet applications. In this paper, we compared and analyzed the performance of the RBS and TDP mechanisms in the view of the number of generated messages and the synchronization accuracy. The reason that we chose...

This study is to propose new method, called by TDP (time dependenet parameter) anlaysis, of physiological signal processing for emoiton recognition. TDP consised of delay, activation, half recovery and full recovery. TDP was determined from running average and normalization of physiological signals for finding tonic and phasic reponse according to emotion at entire time range from stimulating e...

The strategy of sustainable development is one of the two important strategies for Chinese economic development. The present small scale thermal power plants cause much pollution, and consume too much energy, so they are being confronted with the crises of existence and management. Accordingly, it is urgent for small scale thermal power plants to carry out study on the crisis management about t...

The life time of a component is defined by the reliability demands place on it due to its operating environment and operation conditions. To evaluate the necessarily thermal / power cycle stability of a power semiconductor module in a hybrid electrical vehicle (HEV), a vehicle driving cycle profile is used to calculate the thermal reliability requirements. The calculations are based on power lo...

In this paper, we introduce an aane scaling algorithm for semideenite programming, and give an example of a semideenite program such that the aane scaling algorithm converges to a non-optimal point. Both our program and its dual have interior feasible solutions, and unique optimal solutions which satisfy strict complementarity, and they are nondegenerate everywhere. Abbreviated Title: AAne scal...
