An Algorithm for the Consturction of Admissible Tests of the Weibull Distrbution
(
Qatar University
, 1999 , Article)
The method of H. Al-Rawwash and J. Marden [2] is used here for the construction of an admissible test which dominates a given inadmissible one for testing hyupothesis about the Weibull distribution. The algorithm and its ...
Homomorphisms And Subalgebras Of Ms-Algebras
(
Qatar University
, 1995 , Article)
According to the characterization of MS-algcbras from the subvaricty Kj by mean of the triple construction, we characterize the homomorphisms and the subalgebras of the MS-algcbras. Also, we solve the "Fill-in" problem for ...
Prediction Intervals For Future Sample Mean From Inverse Gaussian Distribution
(
Qatar University
, 1991 , Article)
A random sample Xi, Xz, ..., Xn from Inverse Gaussian distribution I(/x,X) is observed. On the basis of this observed sample a lOOp prediction interval of the mean Y of a future sample Yi, ..., Ym from I(^,^.) has been ...
A Markov Chain Model For River Flow
(
Qatar University
, 1996 , Article)
This paper is concerned with a trinary transformation of river flow. The transformed flow is modeled as a three-states Markov chain and both upcrossing and downcrossing problems are studied simultaneously. The stationary ...
Morphisms Of Affine Schemes And Equivalence Of Categories
(
Qatar University
, 1996 , Article)
In this work we construct the relation between the category R-filt (G(R)-gr) and the category O^ — Filt(O^ — Gr).
The quantum (ungraded) version of this result can be obtained by restricting to parts of zero degree. ...
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].
A 6th-order local approximation by a cubic curve
(
Qatar University
, 1997 , Article)
We derive and present a MAPLE program for the construction of a parametric cubic polynomial curve which has sixth-order contract with a given smooth curve at a given point, thus providing a local sixth-order approximation ...
A Problem In Thermoelasticity With Two Relaxation Times For An Infinite Thermoelastic Layer
(
Qatar University
, 1995 , Article)
The problem of a ihcrmoclastic layer of finite thickness and infinite extent is considered within the context of the theory of thcrmoclasticity with two relaxation times. The upper surface of the layer is taken as stress ...
Collineations Of Polar Spaces
(
Qatar University
, 1990 , Article)
In this paper we consider general embeddable polar spaces with Witt index at least three.
If π : S( ξ) —> S( ξ’) be a thick collineation between polar spaces with i( ξ) =i( ξ’) ≥3. Then there exists a place Ø: k—> k' U ...
A Problem In Magneto-Thermoelasticity For A Hollow Circular Cylinder With Thermal Relaxation
(
Qatar University
, 1997 , Article)
The problem of an infinitely long annular cylinder whose inner surface is thermally insulated and whose outer surface is kept at a constant temperature is considered in the presence of an axial uniform magnetic field. The ...
