Modular Multilevel Converter-Based Bipolar High-Voltage Pulse Generator with Sensorless Capacitor Voltage Balancing Technique
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
In order to generate bipolar high-voltage (HV) pulses across certain load from HV dc (HVdc) power supply, a voltage source inverter (VSI) stage should be inserted between the load and the supply. In order to meet the ...
Performance analysis of full-duplex multiuser decode-And-forward relay networks with interference management
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, a cooperative communications scheme with interference management is proposed for Full-Duplex (FD) multi-user, decode-And-forward (DF) relay networks. The scheme is based on a relay selection method that ...
Determining the Outdoor Air Ventilation with Carbon Dioxide (CO2) as a Tracer Gas
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Insufficient ventilation can lead to occupant complaints of discomfort and reduced productivity as human and building generated pollutants build up. Some combinations of these elevated pollutants may have short or long-term ...
Development of Green Inhibitors to Prevent Hydrates Formation, Protect Environment and Reduce Energy Cost in Oil and Gas Industry
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Gas hydrates are identified as ice-liked solid, crystalline compounds having polyhedral water cavities, where gas molecules get trapped during operation under high pressure and low temperature condition. These hydrates ...
Solar Thermochemical CO2 Utilization via Ceria Based Redox Cycle
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
According to the recent studies, it is expected that the global energy requirement will increase from 14 TW to 30 TW by the year 2050. Currently, fossil fuels are the major energy source utilized for the fulfillment of the ...
Performance Analysis of Multiphase High Power Open End Drives Fed from Dual Matrix Converter
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
In this paper an open ended seven phase stator winding drive is considered for analysis that is to be fed from matrix converter controlled by space vector pulse width modulation scheme. Open-end winding variable speed ...
An Arabic Text-to-Picture Mobile Learning System
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Handled devices and software applications are susceptible to ameliorate learning strength, awareness, and career development. Many mobile-based learning applications are obtainable from the market but Arabic learning ...
Enhanced Energy Extraction from a Solar Panel
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Due the movement of the sun throughout the day, the insolation level incident on the fixed panel surface varies largely. The maximum level of insolation occurs only around noon. This leads to the panel to be under-utilised. ...
Ionic Liquids as Multi-purpose Inhibitors to avoid Natural Gas Hydrates during Gas Processing
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
The issue of hydrate formation during gas processing is a challenging problem for the oil and gas industries. Billions of dollars spent annually to get rid of the blockage of pipelines due to hydrate clogging by applying ...
Occupant's thermal comfort in Qatari offices - Need for the new adaptive standard
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Qatar's per capita energy consumption is one of the highest in the world, consuming 30.184 TWh as of 2012. Buildings contribute significantly (80%) to this, with air-conditioning taking a lion's share. Qatar does not have ...
