Traditionally, research into circuit-switched (C-S) networks has been divided into two areas, reliability and performance, each making little reference to the other. More recently, however, research has focused on unification of the two. One possible choice for a combined performance and reliability measure is the overall network grade-of-service (NGOS), i.e. the overall probability of blocking...

We study the problem of computing the reliability of a network operated using the OSPF protocol where links fail with given independent probabilities. Our measure of reliability is the expected lost demand in the network. Computing this measure is #P-complete, so we developed approximation methods based on related work for circuit-switched networks. Preliminary results show the robustness of op...

Technology development and continuous down scaling in CMOS fabrication makes Mixed Signal Integrated Circuits (MSIC) more vulnerable to process variation. This paper presents a well defined novel design methodology for process variability aware design by incorporating the major challenge of statistical circuit performance relating the device and circuit level variation in an accurate and effici...

Integrated circuits are often designed using simple and conservative 'design rules' to ensure that the resulting circuits will meet reliability goals. This simplicity and conservatism leads to reduced performance for a given circuit and metallization technology. To address this problem, we had developed a TCAD tool, ERNI, which allows process-sensitive and layout-specific reliability estimates ...

Driving mode of MEMS (Micro-Electro-Mechanical Systems) Vibratory Gyroscope is discussed in the paper. We analyze the closed-loop circuit of MEMS gyroscope from two aspects of amplitude fixed and frequency locking. In the amplitude fixed circuit, Automatic Gain Control (AGC) circuit is employed to update the amplitude of the driving force, together with a PI controller to improve the accuracy a...

As semiconductor manufacturing entered into nanoscale era, performance degradation due to Negative Bias Temperature Instability (NBTI) became one of the major threats to circuits reliability. In this paper, we present a model and analysis of NBTI impact on circuit delays. First, we model NBTI impact on gate intrinsic delay and output transition delay. The insights of our models reveal that NBTI...

This study aimed to investigate the validity and reliability of global (GPS) and local (LPS) positioning systems for measuring distances covered and sprint mechanical properties in team sports. Here, we evaluated two recently released 18 Hz GPS and 20 Hz LPS technologies together with one established 10 Hz GPS technology. Six male athletes (age: 27±2 years; VO2max: 48.8±4.7 ml/min/kg) performed...
