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. ...
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 ...
Common-mode voltage and vibration mitigation of a five-phase three-level NPC inverter-fed induction motor drive system
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
Common-mode (CM) voltage is one of the main reasons for the flow of bearing currents in induction motors (IM) that ultimately leads to the bearing failure and causes severe vibrations. For three-phase IM drives, many works ...
Area spectral efficiency of infrastructure relay enhanced cellular systems
(
Institution of Engineering and Technology
, 2016 , Article)
In this study, the authors investigate the downlink area spectral efficiency (ASE) of infrastructure relay enhanced cellular systems. ASE for cellular systems is defined as the maximum achievable data rate per unit bandwidth ...
