A Bayesian system identification methodology is proposed for leakage detection in water pipe networks. The methodology properly handles the unavoidable uncertainties in measurement and modeling errors. Based on information from flow test data, it provides estimates of the most probable leakage events (magnitude and location of leakage) and the uncertainties in such estimates. The effectiveness ...

Side-channel attacks generally rely on the availability of good leakage models to extract sensitive information from cryptographic implementations. The recently introduced leakage certification tests aim to guarantee that this condition is fulfilled based on sound statistical arguments. They are important ingredients in the evaluation of leaking devices since they allow a good separation betwee...

This paper proposes a new heuristic approach to determine the input pattern that minimizes leakage currents of nanometer CMOS circuits during sleep mode considering stack and fanout effect. The proposed approach uses a new precise macro-modeling of leakage current considering subthreshold leakage, gate tunneling leakage, body effect, stack effect, and fanout effect. The macro-model is developed...

In this paper we propose a new model for leakage mechanism in tail-mode bits of DRAM data retention characteristics. For main-mode bits, leakage current can be attributed to junction thermal-generation leakage current. For tail-mode bits, it is found for the first time that Gate-Induced Drain Leakage (GIDL) current has a dominant impact. The root cause is electric field enhancement caused by me...

INTRODUCTION Endodontic surgery is a valuable option for maintaining patient's natural dentition when previous orthograde endodontic treatments fail to succeed. Proper root-end preparation and placement of a retro-filling material are recommended for successful endodontic surgery. The objective of this experimental study was to compare sealing ability of Resilon/Epiphany system, as a potential ...

OBJECTIVE To describe a new intraoperative bile leakage test in patients undergoing a major liver resection aimed to combine the advantages of each of the other standard bile leakage tests (accurate visualization of leaks, reproducibility, and ease of use) without their disadvantages. METHODS At the end of the major hepatic resection, 10 to 30 mL of sterile fat emulsion, 5%, is injected via a...

For more than four decades, the simple structure of the dynamic RAM (DRAM) cell and continuous improvement in lithography and dry-etching technology has made DRAM grow exponentially in a large-scale integration and has decreased the minimum feature size in memory chips. In the field of testing, more appropriate test algorithms are required to protect DRAM cell data.In this paper an Interleaving...

BACKGROUND Various materials have been added to mineral trioxide aggregate to enhance its properties. This study was aimed to compare the sealing efficacy of MTA with and without nanosilver using bacterial leakage approach. MATERIAL AND METHODS Seventy canine teeth were prepared and obturated. Then, after apical resection, the root-end cavities were prepared by ultrasonic retrotips. Teeth wer...
