Optimum Cutting Schedule Of Reinforcing Steel Bars
(
Qatar University
, 1999 , Article)
Reinforcing steel bars are generally procured in standard lengths. The cutting of standard steel bars to the specified lengths usually yields an appreciable amount of steel waste. Minimization of steel waste problem is of ...
Paraboloid Shell As Footing
(
Qatar University
, 1999 , Article)
A simplified method for the design of paraboloid shell footing base on the displacement of the shell's crown where the column axial load is transferred to the footing has been developed. A case study was presented to ...
A New Technique To Predict Multilayered Reservoir Characteristics Using Pulse Testing Data
(
Qatar University
, 1998 , Article)
In this study, a mathematical model was developed to present pulse and interference testing for multilayered reservoirs. It was found that apparent storage calculated from pulse testing data is always less than or equal ...
A Comparison Between Artificial Neural Network And A Geostatistical Technique In The Estimation Of Regionalized Variables
(
Qatar University
, 1999 , Article)
In all mining estimation techniques data play a very important role. Insufficient data would mean the quality of the estimate is unreliable. Due to the importance attached to a good and representative data set, the application ...
Computation Of Normal Depth In Open Channels
(
Qatar University
, 1998 , Article)
Fixed-point iteration is an efficient technique for manual and machine calculation of normal depth. The method is applied to the solution of Manning's equation for two basic uniform flow problems in trapezoidal and circular ...

(
Qatar University
, 1998 , Article)
Water plays an important role in human life and development. The evaluation, planning and management of water resources become important in sustaining human life, specially in arid and semi arid regions. This paper aims ...
High Frequency Characteristics Of Ferrite Materials And Applications To Microstrip Circuits
(
Qatar University
, 1999 , Article)
Dispersion behavior of the parameters of microstrip lines printed on ferrite substrate is presented. The characteristic impedance for lines on magnetized ferrite substrates are obtained for partially magnetized substrates ...
Concrete Pavement Truck Equivalence Factors For Upgrades
(
Qatar University
, 1999 , Article)
Presented in this paper are the upgrade truck equivalence factors for
single unit trucks of type, 1.2 and 1.22 which are not covered by
AASHTO. The equivalency factors for front and rear axles of single
unit trucks were ...
New Algorithms For Digital Analysis Of Power Intensity Of Non Stationary Signals
(
Qatar University
, 1998 , Article)
Discrete and continues time-frequency algorithms of the power intensity of non-stationary signals are proposed. Results show that the power intensity waveform analysis performed well in both discrete and continuous ...
Soil Classification Decision Support System Using An Expert System Approach
(
Qatar University
, 1998 , Article)
Soil classification systems are necessary for the identification of soil properties. Expert systems can be a very powerful tool in identifying soils quickly and accurately. In this paper, an interactive and user-friendly ...
