التعاون الدولي في مواجهة الجريمة الإلكترونية
(2018 , Conference Paper)
أمام التطور التقني السريع الذي اتسمت به الحياة الدولية حاليا وما اقترن به من إساءة استخدام التكنولوجيا ، الإلكترونية وتوظيفها في ارتكاب الجرائم خاصة في مجال وسائط الاتصال الحديثة التي تعتمد على الآليات الإلكترونية استلزم ...
Novel shunt-less filters for grid-connected transformerless photovoltaic applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
The existing ground leakage current suppression methodologies are effective when Photovoltaic (PV) arrays' stray capacitors are small (in several nano-Farads). In such case, the High Frequency (HF) content of the inverter's ...
Fault tolerant vector controlled five-phase permanent magnet synchronous motor drive with an open phase
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
Recently, multiphase permanent magnet synchronous motor drives have gained attention in applications which require high reliability. The multiplication of phase number guarantee to the system to continue operating in post ...
Adaptive distributed fault diagnosis design for large-scale networks of nonlinear systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
The main aim of this paper is to synthesize a distributed adaptive sliding mode observer scheme for fault diagnosis of large-scale nonlinear dynamical networks. Each node dynamics includes both linear and nonlinear terms ...
Relay selection in FDD amplify-and-forward cooperative networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
In this paper, the problems of relay selection and distributed beamforming are investigated for bi-directional dual-hop amplify-and-forward frequency-division duplex cooperative wireless networks. When using individual ...

(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
Owing to the expeditious growth in the information and communication technologies, smart cities have raised the expectations in terms of efficient functioning and management. One key aspect of residents' daily comfort is ...
Ground-borne vibration investigation by model-ling the tunnel-soil interaction using a finite element package
(
International Institute of Acoustics and Vibration, IIAV
, 2018 , Conference Paper)
In 2013, Qatar Rail announced major rail projects that include an urban rail network for the city of Doha with lines running on the surface and underground which are expected to be in operation by 2020. Railway systems are ...
Electrolytic capacitor-less dual buck inverter with CM and DM active resonance damping control for Non-isolated grid-connected PV applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
The shoot-through problem of conventional H-Bridge inverters imposes a threat to system's reliability and efficiency. This is because the unintentional shoot-through state short-circuits the DC-Link capacitor. To overcome ...
Optimization of energy pile conductance using finite element and fractional factorial design of experiment
(
Institute of Physics Publishing
, 2018 , Conference Paper)
In Ground Source Heat Pumps (GSHP), Energy Piles pose as heat exchangers that transfer the heat from the buildings to the shallow ground lower temperature in order to decrease the energy consumption whilst cooling the ...
Modeling Performance Measurement of Mobile Manipulators
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
Mobile manipulators are being marketed around the world as single manufacturer systems (i.e., robot arm and vehicle manufactured by the same organization) and as independent robot arms, from a different manufacturer and ...
