Hydrate Technology For Transporting Natural Gas
(
Qatar University
, 2003 , Article)
Natural gas hydrate (NGH) is a viable alternative to LNG (Liquefied Natural Gas) or pipelines for the transportation of natural gas from source to demand. It involves three stages: production, transportation and re-gasification. ...
Differential Amplitude Phase Shift Keying (Dapsk): A New Modulation Method For A Turbo Code In Digital Radio Broadcasting
(
Qatar University
, 2003 , Article)
The multilevel modulation techniques of M–Differential Amplitude Phase Shift Keying (DAPSK) have been proposed in combination with Turbo code scheme for digital radio broadcasting bands below 30 MHz radio channel. Comparison ...
Non Uniform Differential Amplitude Phase–Shift–Key (Dapsk) Modulation For Multimedia Multicast Wireless Communications With Punctured Convolutional Coding
(
Qatar University
, 2003 , Article)
Simple closed–form expressions for the probability of error for nonuniform M–ary Differential Amplitude Phase–Shift–Key (DAPSK) signaling over an Additive White Gaussian Noise (AWGN) and Rayleigh fading channels are ...
Can Nmr Solve Conventional Logs Interpretation Problems In Low Resistivity Beds Evaluation
(
Qatar University
, 2003 , Article)
This paper presents some cases of low resistivity reservoirs and low contrast resistivity reservoirs where conventional logs fail to determine the petrophysical properties of formation. The problems of these reservoirs are ...
A Demodulation Technique For Power System Local Frequency And Voltage Measurements
(
Qatar University
, 2003 , Article)
The demodulation technique of two complex signals is used to estimate the power system local frequency and voltage phasor. The first complex signal is generated from the three-phase voltage waveform by using the ...
Predict The Properties Of Aqueous Mixed Electrolyte Solutions From Properties Of The Individual Electrolyte Solution
(
Qatar University
, 2003 , Article)
For calculating the thermodynamic properties of mixed electrolyte solutions, a thermodynamic framework is developed. The vapor pressure, density and osmotic coefficient of several mixed electrolyte solutions are predicted ...

(
Qatar University
, 2002 , Article)
This work presents an assessment of the potential and economical feasibility of adopting wind energy as a renewable source of energy in Qatar. An analysis is presented for the long term measured wind speed (1976-1989) at ...
Structure Mixture Response Of Buildings Due To Simulated Earthquake Loading
(
Qatar University
, 2002 , Article)
This paper presents two case studies to evaluate the performance of the structure mixture theory in the earthquake response analysis of buildings. In the first case study, the actual earthquake responses of the two-story ...
Finite Element Analysis Of Tubular Induction Accelerators
(
Qatar University
, 2001 , Article)
The paper develops a method of analyzing tubular induction accelerators based on the finite element technique. The method takes end effects (due to current discontinuities at the rotor edges) into consideration. The ...
