Rainfall Change Projections under Different Climate Change Scenarios in UAE
( Qatar University Press , 2023 , Conference Paper)The increase of greenhouse gases in the atmosphere due to human activities is predicted to have significant and lasting effects on the global climate throughout the 21st century. The resulting warming over the past decades ... -
Rainfall Characterization In An Arid Area
( Qatar University , 1991 , Article)The objective of this work is to characterize the rainfall in Doha which lies in an arid region. The rainfall data included daily rainfall depth since 1962 and the hyetographs of the individual storms since 1976. The ... -
A Random Binary Trees Generation Method
( Qatar University , 2000 , Article)There are two widely used random distributions on binary trees, namely the binary search tree distribution and the uniform distribution. By analyzing the performance of algorithms that manipulate binary trees generated at ... -
Random Distributed Algorithms For Clock Synchronization
( Qatar University , 1992 , Article)This paper proposes clock synchronization algorithms based on the idea in which randomly chosen m out of the total N processors cooperate to perform the clock adjustment of all processors in a distributed system. Selection ... -
Rapprochement between Sunnīs and Imāmīs during the Crusades
( جامعة قطر , 2018 , Article)The Imāmī Shī‘a of Syria stood along with the Sunnīs as one group against the Franks, rather than as followers of different religious traditions. This article traces the rapprochement between the Sunnī and the Imāmī Shī‘a ... -
A Rational Exponential Model for Unconstrained Non-Linear Optimization
( Qatar University , 2002 , Article)In this Paper, a new algorithm based on the non-quadratic model is suggested for solving unconstrained optimization problems which modifies the classical conjugate gradiant methods. This technique has the same properties ... -
A rational logarithmic model for unconstrained non-linear optimization
( Qatar University , 1997 , Article)A new non-quadratic model is proposed for solving unconstrained optimisation problems which modifies and develops the classical conjugate gradient methods. The technique has the same properties as the classical conjugate ... -
Rational Synthesis, Characterization, and Application of Environmentally?Friendly (Polymer?Carbon Dot) Hybrid Composite Film for Fast and Efficient UV Assisted Cd2+ Removal from Water
( Qatar University Press , 2020 , Poster)Carbon-dots (CDs) are of particular interest in numerous applications. However, their efficiency for heavy metal removal from wastewater was not yet reported. Herein, we rationally synthesized CDs from petroleum-coke-waste ... -
Rayn formation, a new name for the permian khuff formation (S. S.) In saudi arabia
( Qatar University , 1991 , Article)The rank of the Khuff Formation (late Carboniferous-late Permian) in Saudi Arabia is raised to group status and it is divided into Unayzah (late Carboniferous-early Permian) and Rayn (middle-late Permian) Formations. The ... -
Re-defining the Role of Interactive Architecture in Social Relationships
( Qatar Univesrity Press , 2021 , Conference Paper)With rapid advance of new technologies and mediated built space has shifted from a static context of functions serving users to a new participant of social relationships. Interactive abilities and computational power allow ... -
Re-forming the knot - ʿabdullāh al-ghumārī's iconoclastic sunnī neo-traditionalism
( جامعة قطر , 2018 , Article)This article studies the life and thought of Abdullah al-Ghumari (d. 1413/1993), an accomplished, yet uncelebrated, Muslim scholar from Morocco. After a brief biographical sketch, I present an overview of his thought ... -
Recent Advances In Coring And Core Analysis Technology New Technique To Improve Reservoir Evaluation
( Qatar University , 2000 , Article)The main goal of core analysis is to reduce uncertainty in reservoir evaluation by providing data representative of the reservoir at in situ conditions. Basic core analysis measurements are unchanged, but advances in core ... -
Recent Benthic Foraminifera from the Local Water of Qatar, Arabian Gulf
