Proposal of a p-type Back-Enhanced Tunnel Field Effect Transistor
(2019-04-01)
In this paper we propose a new p-type Tunnel Field Effect Transistor based on the planar Back-Enhanced structure (BE-pTFET), by removing the p-type drain doping and using a back bias to obtain similar on-state behaviors ...
On speech enhancement algorithms based on mmse estimation
(2015-01-01)
This paper addresses the problem of single microphone frequency domain MMSE noise reduction technique for speech enhancement in noisy environments. We first analysed asymptotic performance of the MMSE estimate and compared ...
Capacity of active power reserve for frequency control enhanced by distributed generators
(2013-12-01)
Usually, ancillary services are provided by large conventional generators; however, with the growing interest in distributed generation to satisfy energy and environmental requirements, it seems reasonable to assume that ...
Resilience enhancement in the planning of medium-and low voltage power distribution systems with microgrid formation
(2021-01-01)
A resilience enhancement approach applied to medium- and low voltage (MV/LV) systems planning is proposed. In the mathematical model formulation, substations, distribution transformers, cables, switches, renewable generators, ...
Atmospheric plasma treatment of carbon fibers for enhancement of their adhesion properties
(2014-01-01)
Plasma processing of carbon fibers is aimed to provide better contact and adhesion between individual plies without decrease of the carbon fiber (CF) mechanical resistance. This work deals with surface modification of CFs ...
ENCORE Enhanced Code Galileo Receiver for Land Management Applications in Brazil
(Ieee, 2010-01-01)
Taking benefit of the new Galileo ranging signals, the ENCORE (Enhanced Code Galileo Receiver) project aims to develop a low-cost Land Management Application to cover needs of the Brazilian market in terms of geo-referencing ...
Pool boiling heat transfer enhancement using micro-fin surfaces and dielectric fluids
(2020-01-01)
One promising way to enhance the heat transfer coefficient (HTC) and the critical heat flux (CHF) is modifying the heating surface morphology by using machining techniques, coating, and chemical processes. Microstructured ...
Optimal location of FACTS devices for generation costs reduction and stability enhancement
(2014-11-10)
This research proposes a new approach for the problem of FACTS equipment optimal location in a transmission system. SVC and TCSC devices help to increase the controllability of flow over the lines and at the same time ...
Performance enhancement of switched affine systems by switched quadratic Lyapunov functions: Applications in DC-DC converters
(2013-01-01)
This paper proposes design methodologies to include the convergence rate to Switched Affine Systems, intending to reduce the current overshoot in DC-DC converters. The initial step consists in finding Lyapunov matrices for ...
