ON THE CRYSTAL AND HYPERFINE PARAMETERS OF THE HEXAGONAL Ba Cax Sr1_xFe4 O8 MONOFERRITES
( Qatar University , 1983 , Article)The alkaline earth monoferrites BaCaxSr1-xFe4O8 with X = 0,0.5and 1, were studied by Mossbauer spectroscopy and neutron diffractometry over a wide range of temperatures (78 - 900 K). The lattice constants were obtained ... -
On the Design of Bit-Slice Processors
( Qatar University , 1988 , Article)In the past decade, fixed instruction microprocessors have evolved from 4 bits to 32 bits. Their compact design and relative low cost have made them very popular with design engineers. Their use extends into a lot of ... -
On the direct problem and scattering data for a singular system of differential Equations with discontinuous coefficients
( Qatar University , 1996 , Article)A system of Sturm-Liouiville differential equations of order n with a density matrix function is considered. The direct problem of the considered system is studied and hence the scattering data of the problem is obtained. -

( Qatar University , 1993 , Article)Prawn fisheries in the Gulf of Suez constitute about 13.7% of the total fish and shrimp landings. About 11% are made up by three penaeid species namely: Penaeus japonicus Bate, Penaeus semisulcatus De Han and Penaeus ... -
On the Propagation of Elastic-plastic Wave in the Half Space
( Qatar University , 1981 , Article)The problem of the propagation of the elastic-plastic wave in the half-space occupied by and elastic-plastic medium has been studied. Treatments were carried out under the Assumption of perpendicular load, on the boundary, ... -
On the solution of Bicriterion Inter Nonlinear fractional programs with fuzzy parameters in the objective functions
( Qatar University , 2001 , Article)In this paper we consider bicriterion integer nonlinear fractional programs having fuzzy parameters in the objective functions. For such programs, a solution algorithm is described to solve the formulated model. The results ... -
On The Solution Of The Job-Shop Scheduling Problem Under Fuzzy Environment
( Qatar University , 2002 , Article)This paper presents a solution algorithm for solving the job-shop scheduling problem involving fuzzy parameters in the constraints. It is considered that the processing times are those fuzzy parameters and the maximum ... -
