(
كلية الحقوق والعلوم السياسية
, 2014 , Conference Paper)
لم تنظم مجلة الالتزامات و العقود عيب الاستغلال بمواد صريحة و لكن استقراء العديد من المواد الواردة في باب عيوب الرضى و مقارنتها بالمصادر التاريخية بمجلة الالتزامات و العقود و على رأسها القانون الألماني يفضي إلى اكتشاف أن ...
The Relationship Between Leptin and PCOS
(
De Gruyter
, 2014 , Conference Paper)
Background: The ob gene produces a leptin hormone that works
as a satiety signal to the hypothalamus. Leptin may have a role in polycystic ovary syndrome (PCOS) via its role on obesity and insulin resistance.

Conservation And Development Of Cultural Heritage In Doha
(
Hamad bin Khalifa University Press (HBKU Press)
, 2014 , Conference Paper)
Throughout the world, many urban designers and architects have been working toward the protection, preservation and enhancement of urban heritage in order to increase its usefulness as well as preserve the cities' cultural ...
HVDC shunt tap based on series-input parallel-output DC-AC multi-module VSCs with DC voltages balancing
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Conventionally, tapping-off a small amount of power from an HVDC transmission line to a three-phase local network can be achieved using a DC-to-AC voltage source converter (VSC) followed by a step down transformer. In order ...
Medium voltage flywheel energy storage system employing dual three-phase induction machine with machine-side series-connected converters
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Flywheels as energy storage systems are good candidates for numerous power system applications such as voltage support, serving fluctuating loads, frequency regulation and renewable energy utilization. Most of these ...
Torque ripple reduction of radial magnetic gearbox using axial pole pairing
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Magnetic gearbox (MGB) is a contactless magnet-based transmission system that transmits mechanical power between two shafts. MGBs offer significant advantages over mechanical gears such as contactless power transfer, high ...
Traction system with on-board inductive power transfer
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
In traction applications based on long primary and short secondary type, contactless electrical energy transmission can offer distinct advantages over the conventional energy transmission based on catenary system to provide ...
Quasi seven-level operation of multilevel converters with selective harmonic elimination
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Generally, selective harmonic elimination (SHE) complexity for multilevel inverters increases with the increase in number of levels. In this paper, a novel approach for SHE is introduced. This approach is based on cancelling ...
A five-phase induction machine model using multiple DQ planes considering the effect of magnetic saturation
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Multiphase phase induction machines are usually modeled using multiple dq planes, where complete decoupling between these sequence planes is usually assumed. This assumption may be accepted if the magnetic circuit is assumed ...
