Due to the superlinear dependence of leakage power consumption on temperature, and spatial variations in on-chip thermal profiles, methods of leakage power estimation that are known to be accurate require detailed knowledge of thermal profiles. Leakage power depends on the integrated circuit (IC) thermal profile and circuit design style. Here, we show that piecewise linear models can be used to...

Leakage rates were determined from leaf cells loaded with rubidium and [(3)H]leucine. There was a differential response between leucine and rubidium leakage depending upon the species used. The rate of leucine leakage shows a small decline below 5 C for two altitudinal variants of Lycopersicon hirsutum Humb. and Bonpl., whereas Lycopersicon esculentum L. showed a marked increase below 5 C. Rubi...

Although leakage through a tracheoesophageal shunt prosthesis is the main cause of prosthesis failure in a laryngectomy patient, this has never been the subject of in vitro evaluation. The aim of this study was to compare three commercially available voice prostheses by comparison of their in vitro leakage patterns, in absence or presence of a biofilm. To compare in vitro leakage patterns, a mo...

PURPOSE The aim of the present study was to study whether patients developing anastomotic leakage after colorectal resections for colorectal cancer have laboratory signs of an altered hemostatic balance in the systemic circulation, preoperatively and postoperatively, causing an impaired healing process. METHODS Patients operated on for colorectal cancer were studied. Seventeen consecutive pat...

Conjugate heat transfer problem of a disc winding in a power transformer is studied using commercial CFD software. The study is done for oil flow, temperature distribution, hot spot location and temperature of the winding, for three different cases: first, no oil leakage past the top washer; second, partial leakage due to a 2 mm gap between the top oil guiding washer and cylindrical pressboard;...

Leakage power consumption plays a significant role in current CMOS technology. International Technology Roadmap for semiconductors reports that leakage power consumption dominates the total chip power consumption as technology advances to nano scale. Most of the battery operated applications such as cell phones, Laptops etc requires a longer battery life, which can be made possible by controlli...

In plant chamber studies, if CO2 leaking from a chamber is not quantified, it can lead to an overestimate of assimilation rates and an underestimate of respiration rates; consequently, it is critical that CO2 leakage be determined. Sulfur hexafluoride (SF6) was introduced into the chambers as a tracer gas to estimate leakage rates. Chamber leakage constants were determined by measuring the rate...

Evaluating the side-channel attacks (SCAs) resilience of a crypto device is important and necessary. The SCAs-secure evaluation criteria includes the information theoretic metric and the security metric. The former metric measures the leakage amount of a crypto device. It should be independent with the evaluator. However, the current metrics, e.g. mutual information (MI), conditional entropy an...

Leakage resilient cryptography attempts to incorporate sidechannel leakage into the black-box security model and designs cryptographic schemes that are provably secure within it. Informally, a scheme is leakage-resilient if it remains secure even if an adversary learns a bounded amount of arbitrary information about the schemes internal state. Unfortunately, most leakage resilient schemes are u...

Home Fires have taken a growing toll in lives and property in recent years. LPG is highly inflammable and can burn even at some distance from the source of leakage. Most fire accidents are caused because of a poor-quality rubber tube or when the regulator is not turned off. The supply of gas from the regulator to the burner is on even after the regulator is switched off. By accident, if the kno...
