Calculation Of Mass Yield Distributions In Fission Induced By High Energy Protons
( Qatar University , 1991 , Article)An analytical expression is obtained for the mass-yield distribution in fission induced by high-energy protons, using a two-step model. In the first step, the incident proton penetrates the target nucleus, knocking out ... -
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 ... -
Capabilities/limitations of landsat-tm data for bathymetric analysis of shallow marine environment: A case study
( Qatar University , 1999 , Article)The intensity of the light received by Landsat satellite sensors is inversely proportional to the path length though the sea water column. Since the light passes down to the sea floor and back again, the intensity should ... -
Capital structure and debt maturity: Evidence from listed companies in Saudi arabia
( Qatar University , 2005 , Article)This study examines the determinants of capital structure in general and the determinants of corporate debt- maturity in particular for 56 listed companies in Saudi Arabia. To achieve this objective the study was set to ... -
Cascaded Coding Schemes For Public-Key Cryptography
( Qatar University , 1995 , Article)1976 Diffic and Hellman introduced the concept of public-key cryptography and in 1978, McEliece introduced the first public-key cryptosystem based on error correcting codes. Since that time, several methods have been ... -
A Case Study Of Traffic Characteristics And Proposed Improvement Schemes For An Arterial Road
( Qatar University , 1993 , Article)This case study represents a typical example of surveying and assessing traffic characteristics along a local ring road in Doha City. Expected impacts of possible short-term (5-year) traffic management schemes for two main ... -
Catalytic Oxidation Of Petroleum Waxy Distillates
( Qatar University , 1994 , Article)The catalytic oxidation of petroleum waxy distillate (boiling range 400 - 440°C at 760 nun Hg) using KMn04 catalyst and air was studied in a batch reactor. The effect of reaction temperature (100-160°C), air flow rate ... -
The Category 'D' Reconsidered
( Qatar University , 1999 , Article)This study deals with the categorial status of a set of words known as 'determiners' and the features encoded in them. We argue, following a suggestion in Chomsky, 1975, that 'Optimality' conditions on grammar require ... -
