Effect of chain structure on the properties of Glass fibre/polyethylene composites
(
Elsevier, Ltd
, 2013 , Article)
Three types of polyethylenes (low density: LDPE, medium density: MDPE, and high density: HDPE) were used to investigate the effect of chain branching on the dispersion and adhesion in Glass fibre reinforced polymer composites. ...
Deutsche Bank and the Use of Promises in Islamic Finance Contracts
(
SSRN- Elsevier
, 2013 , Article)
This paper examines the concept of a promise, an essential tool for Islamic financial transactions that has facilitated the development of structured Sharī‘ah-compliant financing arrangements and mitigated much of the risk ...
Scales of flows: Qatar and the urban legacies of mega events
(
Emerald
, 2013 , Article)
In 2022, Qatar will become the first Middle Eastern and Arab country to host such an important Mega-Event as the FIFA World Cup. Global cultural and sporting Mega Events have driven the urban transformation of cities such ...
Generalized theory of mixed pole machines with a general rotor configuration
(
Elsevier B.V.
, 2013 , Article)
This paper introduces a generalized theory for the operation of mixed pole machines (MPMs). The MPM has two stator windings, namely the main winding with pole pairs P1 and the control winding with pole pairs P2. The MPM ...
A voltage-behind-reactance model of five-phase induction machines considering the effect of magnetic saturation
(
IEEE
, 2013 , Article)
Five-phase induction machines are generally modeled using multiple dq planes or using a phase variable model. This paper considers modeling five-phase induction machines using a voltage-behind-reactance (VBR) configuration. ...
Fault current contribution scenarios for grid-connected voltage source inverter-based distributed generation with an LCL filter
(
Elsevier
, 2013 , Article)
Inverter-based distributed generation (IBDG) is characterized by its negligible fault current contribution compared with synchronous generators due to its inherent non-overload capabilities. Thus, IBDG hardly affects the ...
Ride-through capability of grid-connected brushless cascade DFIG wind turbines in faulty grid conditions-A comparative study
(
IEEE
, 2013 , Article)
Doubly-fed induction generator (DFIG)-based wind turbines (WTs) are reported to suffer reliability problems due to the presence of slip-rings, brushes, and the gearbox. These disadvantages encouraged several research groups ...
Optimum power transmission-based droop control design for multi-terminal HVDC of offshore wind farms
(
IEEE
, 2013 , Article)
Power generation through wind is expected to play a major role in the world's future energy portfolio. Nevertheless, wind power integration remains a challenging research area due to the special characteristics of wind ...
An improved performance direct-drive permanent magnet wind generator using a novel single-layer winding layout
(
IEEE
, 2013 , Article)
Direct-drive permanent magnet (PM) generators have become a strong contender in medium and large rating wind energy conversion systems as they not only provide higher efficiency and annual energy production, but also reduce ...
Studying the effect of over-modulation on the output voltage of three-phase single-stage grid-connected boost inverter
(
Elsevier B.V.
, 2013 , Article)
Voltage boosting is very essential issue in renewable-energy fed applications. The classical two-stage power conversion process is typically used to interface the renewable energy sources to the grid. For better efficiency, ...
