Joint optimization of redundancy level and spare part inventories
(
Elsevier Ltd
, 2016 , Article)
We consider a "k-out-of-N"? system with different standby modes. Each of the N components consists of multiple part types. Upon failure, a component can be repaired within a certain time by switching the failed part by a ...
Effects of electron acceptors on removal of antibiotic resistant Escherichia coli, resistance genes and class 1 integrons under anaerobic conditions
(
Elsevier B.V.
, 2016 , Article)
naerobic biotechnologies can effectively remove antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs), but there is a need to better understand the mechanisms. Here we employ bioelectrochemical systems ...
An optimal two-bout strategy with phase change material cooling vests to improve comfort in hot environment
(
Elsevier Ltd
, 2018 , Article)
Cooling vests incorporating phase change material (PCM) packets are used to improve comfort of workers in hot environments. This work aims to investigate by modeling and experimentation the effect of dividing the working ...
The role of statistics in data-centric engineering
(
Elsevier B.V.
, 2018 , Article)
We explore the role of statistics for Big Data analysis arising from the emerging field of Data-Centric Engineering. Using examples related to sensor-instrumented bridges, we highlight a number of issues and challenges. ...
Harmonic modeling of linear and nonlinear loads based on Kalman filtering algorithm
(
Elsevier
, 2004 , Article)
Most harmonic nonlinear load modeling techniques developed in the last two decades, assume that the load connected to the load bus has a constant admittance, inductive or capacitive, which depends on the mode of operation ...
Fuzzy linear parameter estimation algorithms: A new formulation
(
Elsevier
, 2002 , Article)
In this paper, we present a new formulation of a fuzzy linear estimation problem as one of the linear programming where the objective is to minimize the spread of the data points, subject to constraints on each measurement ...
Sensorless sliding mode observer for a five-phase permanent magnet synchronous motor drive
(
Elsevier
, 2015 , Article)
This paper deals with the sensorless vector controlled five-phase permanent magnet synchronous motor (PMSM) drive based on a sliding mode observer (SMO). The observer is designed considering the back electromotive force ...
Modelling and analysis of a three-phase to five-phase transformer
(
Walter de Gruyter GmbH
, 2014 , Article)
Multi-phase systems are the focus of research in recent times due to their inherent advantages compared to the three-phase counterpart. A lot of research effort has been put to develop commercially feasible multi-phase ...
Frequency and harmonics evaluation in power networks using fuzzy regression technique
(
Elsevier
, 2003 , Article)
A new technique for frequency and harmonic evaluation in power networks is proposed in this paper. This technique is based on fuzzy linear regression and uses the digitized voltage samples, which are fuzzy numbers, to ...
A new digital transformation for harmonics and DC offset removal for the distance fault locator algorithm
(
Elsevier
, 2004 , Article)
This paper presents a new application of Park's transformations to identifying the positive sequence of the fundamental components of the three-phase voltage or current signals needed for fault locator algorithm. The problem ...
