Common-mode voltage control through vector selection in three-to-five phase matrix converter
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Multi-phase matrix converters (more than three phase) are distinctively advantageous as because of reduced per-phase current and unity power factor operation. The electrical motors supplied through these converters do have ...
Space vector pulse width modulation scheme for three to seven phase direct matrix converter
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper a generalized multi-phase space vector theory is considered for developing the space vector modulation of a three-phase to seven-phase direct matrix converter (DMC). The modulation is based on the control of ...

CBPP is an important transboundary disease in sub-Saharan Africa whose control is urgent. Participatory data collection involving 52 focus group discussions in 37 village clusters and key informant interviews, a cross-sectional ...
Willingness to pay for contagious bovine pleuropneumonia vaccination in Narok South District of Kenya
(
Elsevier
, 2014 , Article)
Contagious bovine pleuropneumonia (CBPP) is an economically important trans-boundary cattle disease which affects food security and livelihoods. A conjoint analysis-contingent valuation was carried out on 190 households ...
An experimental investigation into crushing behavior of radially stiffened GFRP composite tubes
(
Elsevier Ltd
, 2014 , Article)
State-of-the-art studies of the crushing of composite tubes reveal different factors affecting their crashworthiness. Of those factors, the geometrical property of the tube is of great interest. In the current study, four ...
Advances in vaccination against avian pathogenic Escherichia coli respiratory disease: Potentials and limitations
(
Elsevier
, 2014 , Article Review)
Avian pathogenic Escherichia coli (APEC) is one of the most economically devastating pathogens affecting the poultry industry. This group of extra-intestinal E. coli causes a variety of clinical conditions including ...
Non-communicable diseases in the Arab world
(
Elsevier Ltd
, 2014 , Article Review)
According to the results of the Global Burden of Disease Study 2010, the burden of non-communicable diseases (cardiovascular disease, cancer, chronic lung diseases, and diabetes) in the Arab world has increased, with ...
Axial crushing behavior and energy absorption efficiency of corrugated tubes
(
Elsevier, Ltd
, 2014 , Technical Report)
This paper presents the effect of corrugations on the crushing behavior, energy absorption, and failure mode of circular aluminum tubes. Experimental investigations were carried out on five geometrical types of corrugated ...
Macro-scale direct shear test device for assessing soil-solid interface friction under low effective normal stresses
(
ASTM International
, 2014 , Article)
The paper describes a new macro-scale direct shear test device for assessing the largedisplacement soil/solid interface drained shear strength at low effective normal stresses. The testing method arises from a need to ...
Numerical study on settlement of piled foundations on homogenous rock
(
Taylor and Francis
, 2014 , Conference Paper)
Settlement behavior of piled foundations on homogenous rock was investigated using an extensive three-dimensional finite element analysis of different piled-foundation models. Effects of pile slenderness ratio, pile spacing, ...
