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 ...
Caloric expenditure estimation for health games
(
Hamad bin Khalifa University Press (HBKU Press)
, 2013 , Conference Paper)
With the decline in physical activities among young people, it is essential to monitor their physical activity and ensure their calorie expenditure is within the range necessary to lead a healthy life style. For many ...
A robust method for line and word segmentation in handwritten text
(
Hamad bin Khalifa University Press (HBKU Press)
, 2013 , Conference Paper)
Line and word segmentation is a key-step in any document image analysis system. It can be used for instance in handwriting recognition when separating words before their recognition. Line segmentation can also serve as a ...
Performance of a five-phase boost inverter-fed submersible induction machine
(2013 , Conference Paper)
An electrical submersible pump (ESP) motor is preferably fed from a low voltage variable-frequency drive (VFD) followed by a step-up transformer. The motor and drive connection through a long feeder usually causes over ...
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 ...
Modified modulation scheme for photovoltaic fed grid-connected three-phase boost inverter
(
IEEE
, 2013 , Conference Paper)
Transformer-less photovoltaic (PV) inverters are the major functional units of modern grid-connected PV energy production systems. In general, two power conversion stages are required when low-voltage unregulated photovoltaic ...
A Simulink model of an active island detection technique for inverter-based distributed generation
(
IEEE
, 2013 , Conference Paper)
With the increased involvement of Distributed Power Generation Systems (DPGSs) into the conventional power system, the structure has evolved and therefore has brought in various challenges albeit improving flexibility and ...
Study of voltage source converter-based HVDC system during DC side faults
(
IEEE
, 2013 , Conference Paper)
Recently voltage source converter-based HVDC technology has witnessed a remarkable development due to the several advantages it exhibits over the conventional HVDC systems. However, one of the main remaining challenges is ...
Sensorless V/f control with MRAS speed estimator for a five-phase induction machine under open-circuit phase faults
(
IEEE
, 2013 , Conference Paper)
This paper introduces a sensorless scalar controller with MRAS speed estimator based on simple Proportional Resonant PR controllers to provide a disturbance-free operation to a five-phase induction machine under phase open ...
Inductive power transfer with wireless communication system for electric vehicles
(
IEEE
, 2013 , Conference Paper)
This paper explores the employment of inductive power transfer and data transfer (IPDT) for charging of electric vehicles (EV). The main objective of this paper spans the analysis and development of the inductive power ...
