Numerical conformal mapping onto the entire complex plane bounded with finite straight slit and logarithmic spiral slits
(
Institute of Physics Publishing
, 2019 , Conference Paper)
This paper presents a fast boundary integral equation method with for computing conformal mappings of multiply connected regions. We consider the canonical region consists of the entire complex plane bounded by a finite ...
Artificial Neural Network versus Linear Models Forecasting Doha Stock Market
(
Institute of Physics Publishing
, 2018 , Conference Paper)
The purpose of this study is to determine the instability of Doha stock market and develop forecasting models. Linear time series models are used and compared with a nonlinear Artificial Neural Network (ANN) namely Multilayer ...
Synthesis and characterization of Cu-doped TiO2 thin films produced by the inert gas condensation technique
(
Institute of Physics Publishing
, 2017 , Conference Paper)
The bandgap of thin films Cu-doped TiO2 nanoclusters prepared using the inert gas condensation (IGC) technique have been investigated at various Cu contents. The samples were characterized using XRD, SEM/EDS and UV-visible ...
"The use of Arabic version of Social Communication Questionnaires (SCQ) in School Screening for Autism Spectrum Disorder (ASD) in Qatar"
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Introduction: The prevalence rate of Autism Spectrum Disorder (ASD) in Qatar is uncertain, obtaining a reliable estimate is important in shedding the light on the magnitude of the problem, and help in better planning for ...
Spatial Covariate Adjusted Survival Rates for Middle East Respiratory Syndrome (Mers) Coronavirus in the Arabian Peninsula
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
The frequent outbreaks of novel or emerging infectious diseases are alarming. There is a need for urgent and appropriate intervention that can be adapted quickly for such diseases. Middle East respiratory syndrome coronavirus ...
A superconducting millimetre switch with multiple nano-bridges
(
International Symposium on Space Terahertz Technology
, 2014 , Conference Paper)
In this paper, we describe the design of a planar superconducting on/off switch comprising a high normal resistance nano-bridge deposited across a slotline transmission line. We present preliminary experimental results ...
Ion beam modification of surface properties of polyethylene
(
Elsevier
, 2003 , Conference Paper)
Improvement of polymer tribological properties is an essential issue for their application when used as parts of machines or artificial human joints. Ion implantation is a very promising technique in this respect. This ...
Social And Behavioral Risk Factors Influencing Driver's Involvement In Rd Traffic Accidents In Qatar
(
Hamad bin Khalifa University Press (HBKU Press)
, 2014 , Conference Paper)
On average, traffic accidents kill around 137 people around the world every hour. In 2004, road injuries were the first leading cause of death and predicted to be the fifth leading cause of death by 2030. Although the ...
Production of hazardous gas sensors using spinel ferrite nanoparticles
(
Hamad bin Khalifa University Press (HBKU Press)
, 2018 , Conference Paper)
This work reports on sensitive and selective gas sensors based on copper ferrite (CuFe2O4) nanoparticles. The nanoparticles were produced different methods including: colloid microwave assisted hydrothermal method, and ...
Dimensional regularization of the spatial wave function for a singular contact interaction in the relativistic schrodinger equation
(
Institute of Physics Publishing
, 2016 , Conference Paper)
Based on our previous work in PRD 89, 125023 (2014), we stress here (for the first time) the regularization of the spatial wave function for the δ-contact interaction within the relativistic Schrodinger equation. The ...
