Power gating technique reduces leakage power in the circuit. However, power gating leads to large voltage fluctuation on the power rail during power gating mode to active mode due to the package inductance in the Printed Circuit Board. This voltage fluctuation may cause unwanted transitions in neighboring circuits. In this work, a power gating architecture is developed for minimizing power in a...

STUDY DESIGN Case series with chart review. METHODS Charts of consecutive patients fitted with custom-made mandibular advancement devices for t...

The 1990s saw the introduction of three European directives that aimed to harmonise medical device legislation within Union (EU) and these were given effect in United Kingdom (UK) by Medical Devices Regulations 2002 (Statutory Instrument 2002/618 [UK MDR 2002]). Dental professionals EU who manufactured custom-made devices required do so accordance with relevant requirements one directives, Coun...

this study aims to examine how iranian efl learners perceive and apply mitigation devices in request speech act in 4 asymmetrical situations. role-play interactions and questionnaires were used to elicit the required data from iranian informants (male vs. female). the results obtained from the analysis of data revealed that in identical situations, male requestors were comparably more certain t...

Today, complex systems are mainly integrated in CMOS technology, which is facing issues in advanced process nodes, in particular for power consumption and heat dissipation. Magnetic devices such as Magnetic Tunnel Junction (MTJ) have specific features: non-volatility, high cyclability (more than 10) and immunity to radiations. Combined with CMOS devices they offer specific and new features to d...

This paper presents a haptic virtual reality tool developed to enhance the accessibility for the visually impaired. The proposed approach focuses on the development of a highly interactive haptic virtual reality system that allows visually impaired, to study and interact with various virtual objects in specially designed virtual environments. The system is based on the use of the CyberGraspTM a...

Finite impulse response (FIR) filtering is a ubiquitous operation in digital signal processing systems and is generally implemented in full custom circuits due to high-speed and low-power design requirements. The complexity of an FIR filter is dominated by the multiplication of a large number of filter coefficients by the filter input or its time-shifted versions. Over the years, many high-leve...

| Subthreshold digital circuits minimize energy per operation and are thus ideal for ultralow-power (ULP) applications with low performance requirements. However, a large range of ULP applications continue to face performance constraints at certain times that exceed the capabilities of subthreshold operation. In this paper, we give two different examples to show that designing flexibility into ...

this paper describes how multi-agent system technology can be used as the underpinning platform for voltage control in power systems. in this study, some facts (flexible ac transmission systems) devices are properly designed to coordinate their decisions and actions in order to provide a coordinated secondary voltage control mechanism based on multi-agent theory. each device here is modeled as ...
