This study compared the leakage characteristics of different types of dual-cannula fenestrated tracheostomy tubes during positive pressure ventilation. Fenestrated Portex® Blue Line Ultra®, TRACOE® twist, or Rüsch® Traceofix® tracheostomy tubes equipped with nonfenestrated inner cannulas were tested in a tracheostomy-lung simulator. Transfenestration pressures and transfenestration leakage rate...

A SRAM cell must meet requirements for operation in submicron. As the density of SRAM increases, the leakage power has become a significant component in chip design. The power Consumption is a major issue of today's CMOS Technology. Leakage power is major issue for short channel devices. As the technology is shrinking the leakage current is increasing very fast. so, several methods and techniqu...

Current methods to determine debonding/leakage at the tooth-composite interface are qualitative or semi-quantitative. Our previous work introduced a 3D imaging technique to determine and visualize leakage and its distribution at the interface of cavity wall and composite restoration in model cavities. In this study, an automated program was developed to quantify leakage in terms of area and vol...

| Low supply voltage requires the device threshold to be reduced in order to maintain performance. Due to the exponential relationship between leakage current and threshold voltage in the weak inversion region, leakage power can be no longer negligible in such circuits. In this paper we present a technique to accurately estimate leakage power by accurately modeling the leakage current in transi...

Limited energy consumption in multimedia requires very low power circuits. In this paper we focused on leakage current minimization in single static random access memory (SRAM) cell in 90nm complementary metal oxide semiconductor (CMOS) technology. The leakage current mainly consists of sub threshold leakage current and gate leakage current in 90nm CMOS technology. So minimizing the sub thresho...

Garg, Jain, and Sahai first consider zero knowledge proofs in the presence of leakage on the local state of the prover, and present a leakageresilient-zero-knowledge proof system for HC (Hamiltonian Cycle) problem. Their construction is called (1 + ε)-leakage-resilient zero-knowledge, for any constant ε > 0, because the total length of the leakage the simulator needs is (1 + ε) times as large a...

Abstract: This paper descirbes leakage current characters and discharge phenomenon of outdoor insulators both in the lab and in the field. The results are hoped to be used for online monitoring of the contamination levels. The following contents are introduced in the paper: leakage current monitoring systems, relationships between leakage current and discharge phenomenon, flashover prediction m...

BACKGROUND This study investigated the patient's self-report and clinician's confirmation of tracheoesophageal voice prosthesis leakage patterns (through or around) with or without the cough reflex and whether prosthesis diameter affected the leakage route. METHODS Sixty-six consecutive participants with a total of 200 patient-initiated reasons for prosthesis changes were enrolled prospective...

The mechanisms and characteristics of hot carrier stress-induced drain leakage current degradation in thinoxide n-MOSFET’s are investigated. Both interface trap and oxide charge effects are analyzed. Various drain leakage current components at zero V gs such as drain-to-source subthreshold leakage, band-to-band tunneling current, and interface trapinduced leakage are taken into account. The tra...

objectives: microleakage is a major cause of failure of dental restorations and results in development of secondary caries, tooth hypersensitivity and pulp pathosis. this study aimed to compare the microleakage of class ii cavities filled with two types of composite resins and a compomer and subjected to thermocycling. methods: in this in vitro experimental study, class ii cavities with a gingi...
