Off - Grid Power Supply Solution for Portable Cabins using Solar PV System for Qatar
( Qatar University Press , 2021 , Poster)In this project, a new system for power supply for remote areas has been proposed. In the proposed system, solar PV based system with battery storage for stand-along application has been discussed. In addition, the use of ... -
Offsite Construction in the UK: Economic and Environmental Benefits
( Qatar University Press , 2023 , Conference Paper)In contrast to traditional piece meal onsite construction, offsite construction comprises the planning, designing, production, transporting, and assembly of building elements for speedy site assembly to a higher degree of ... -
Oil Spill Index (OSI) to Sentinel-2 satellite data: QU in International Contribution
( Qatar University Press , 2021 , Poster)An Oil Spill Index (OSI = (B3+B4)/B2) was developed and applied to Sentinel-2 optical satellite data of the European Space Agency (ESA) to map marine oil spills using spectral absorption characters of spectral bands of the ... -
Omega-3 fatty acid-rich fish oil supplementation prevents rosiglitazone-induced osteopenia in aging mice
( Qatar University Press , 2021 , Poster)Rosiglitazone is an effective insulin-sensitizer, however, associated with bone loss mainly due to increased bone resorption, and bone marrow adiposity, and decreased bone formation. We investigated the effect of the ... -
On 2n+L-Vertex-Free Graphs
( Qatar University , 1983 , Article)We shall introduce the concepts of pseudoadjacent, pseudocoatraction and pseudoho-momorphism. We shall show, with the help of these concepts, in theorem 2 that every quadrilateral graph V (which is a 4-vertexgraph) has ... -
On A Kp Class Of Partial Differential Equations Conservation Laws And Solitary Wave Solutions
( Qatar University , 1996 , Article)It is shown that a KP class of partial differential equations possesses an infinite number of conservation laws. In addition, exact and explicit solitary wave solutions are constructed for the KP class of equations, which ... -
On a mixed boundary value problem for elliptic equations
( Qatar University , 1988 , Article)In this work, a general form of linear and quasilinear elliptic equations is considered. In the presence of boundary singularities, some estimations for the error, according to the net method, are obtained. -
On A New Haemogregarine Of Varanus Griseus From Egypt
( Qatar University , 1996 , Article)Ten monitors, Varanus griseus collected from various localities in Egypt were examined for protozoan blood parasites. A new species of the genus Haemogregarina senso lato is reported from six of these monitors. Blood forms ... -
On A Relation Between Two Absolute Summability Methods
( Qatar University , 1997 , Article)In this paper we prove a theorem concerning a relation between the summability methods |R,pn,qnlJt and |R,un|fc , k > 1 , which generalizes a result of Bor [2]. -
On an inverse scattering problem with a discontinuous coefficient On the whole line
( Qatar University , 1994 , Article)This paper is devoted to study the inverse scattering problem of a generalized Sturm-Liouville equation on the whole line.The solutions of the considered problem and their asymptotic behaviour are presented.The expansion ... -
On Dirichlet Problem With Singular Integral Boundary Condition
( Qatar University , 1983 , Article)In this paper a Dirichlet problem, with singular integral condition, is studied. It is shown that such problem can be reduced to a regular equation which allows us to construct the solution. -
On estimates of the rate of convergence In the global limit theorems for Homogeneous markov chains
( Qatar University , 1997 , Article)In this paper some estimates are obtained for the remainder term in the limit theorems for the weighted sum of random variables forming a homogeneous Markov chain with arbitrary set of possible states . The achieved results ... -
On Existence Of Two Real Periodic Solutions Of Differential Equations Of Riccati Type
( Qatar University , 1986 , Article)In this paper we consider the two equations z^z^p^z+r^t), (*) z^z^ptOz+r^t), (••) where z € C, p, r) and r^ are real, continuous and periodic with period T. It was shown ... -
On Finite Group Actions On The Solid Klein Bottle
( Qatar University , 1989 , Article)In this paper we classify all G-actions on the solid Klein bottle when G= Z2 and when G= Z^ ® Z2. -
On Improving Communication Software Development Process
( Qatar University , 1995 , Article)This paper aims to standardize the software development process by making use of the well-established hardware development process. The procedure can be applied to any engineering software development process, but we ... -
On Loss Probabilities for Delayed - Access Circuit - Switched Multiplexers
( Qatar University , 1989 , Article)Multiplexing schemes for packetized circuit-switched sources are characterized by an avoidable accessing delay. In the present work it is shown that, contrary to conventional immediate-access multiplexing schemes, one can ... -
