Space vector pulse-width modulation technique for an eleven-phase voltage source inverter with sinusoidal output voltage generation
(
IET
, 2015 , Article)
This study discusses the space vector pulse-width modulation (SVPWM) scheme for an eleven-phase two-level voltage source inverter, aimed at producing a sinusoidal output voltage waveform. Generalised space vector theory ...
Evaluation of the Mechanical Properties of AA 6063 Processed by Severe Plastic Deformation
(
Springer US
, 2015 , Article)
In this study, the mechanical properties, including surface hardness, tensile strength, fatigue, and fretting fatigue behavior of AA 6063 processed by equal channel angular pressing as the most efficient severe shear plastic ...
Multiple parts process planning in serial-parallel flexible flow lines: part I—process plan modeling framework
(
Springer London
, 2015 , Article)
In recent years, integrated process planning and scheduling models have been proposed as solutions that can bridge the gap between practical process planning and production scheduling. However, most structures of these ...
An analytic network process condition assessment model for sewer pipelines
(
Civil-Comp Press
, 2015 , Conference Paper)
As sewer pipelines age, the need for their upgrading, maintaining, and repairing arises. Simultaneously, inadequate sewer pipelines might lead to catastrophic failures. Thus, decision makers must have a detailed knowledge ...
An integrated ANP and er condition assessment model for sewer pipelines
(
International Society for Trenchless Technology
, 2015 , Conference Paper)
As sewer networks age, the need for their maintenance arises. Simultaneously, inadequate rehabilitation of sewer pipelines might cause catastrophic failures. Thus, municipalities worldwide must have a detailed knowledge ...
Enhancement of multi-media filter performance using talc as a new filter aid material: Mechanistic study
(
Elsevier
, 2015 , Article)
The potential of using a new filter aid, namely, talc to enhance the removal of particles in a multi-media filter was investigated. In the case of the nano-scale particles the running time was enhanced by 300. min at a ...
A fouling suppression system in submerged membrane bioreactors using dielectrophoretic forces
(
Elsevier
, 2015 , Article)
A novel method was developed to suppress membrane fouling in submerged membrane bioreactors. The method is based on the dielectrophoretic (DEP) motion of particles in an inhomogeneous electrical field. Using a real sample ...
A high efficiency and high reliability single-phase modified quasi Z-Source inverter for non-isolated grid-connected applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Quazi Z-Source inverter (qZSI) is a promising inverter topology that can buck or boost input voltage without a DC-DC converter and hence can be used in transformerless configuration. This is a high efficiency solution ...
A mixed space-time and wavenumber domain model for predicting ground vibration from railway tracks
(
National Technical University of Athens
, 2015 , Conference Paper)
In this paper, a mixed model for studying ground vibration generated from surface railway tracks is presented. A ballasted track with nonlinear resilient components is modelled in the time domain using the Finite Element ...
Experimental validation of a numerical model for the ground vibration from trains in tunnels
(
DC/ConfOrg
, 2015 , Conference Paper)
Ground vibration and ground-borne noise from trains in tunnels are attracting increasing attention from researchers and engineers. They are important environmental issues related with the operation of underground networks ...
