Investigation of the temperature-relatedwear performance of hard nanostructured coatings deposited on a s600 high speed steel
(
MDPI AG
, 2019 , Article)
Thin hard coatings are widely known as key elements in many industrial fields, from equipment for metal machining to dental implants and orthopedic prosthesis. When it comes to machining and cutting tools, thin hard coatings ...
Constitutive models for the prediction of the hot deformation behavior of the 10%Cr steel alloy
(
MDPI AG
, 2019 , Article)
The aim of this paper is to establish a reliable model that provides the best fit to the specific behavior of the flow stresses of the 10%Cr steel alloy at the time of hot deformation. Modified Johnson-Cook and strain-compensated ...

Synthesis, characterization, and properties of nickel-cobalt layered double hydroxide nanostructures
(
Royal Society of Chemistry
, 2017 , Article)
Nickel-cobalt layered double hydroxides (Ni-Co-LDH) have recently been examined for their potential as battery-type hybrid supercapacitors made from metal hydroxide electrode materials, due to their unique spatial structure, ...
Image Local Features Description through Polynomial Approximation
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
This work introduces a novel local patch descriptor that remains invariant under varying conditions of orientation, viewpoint, scale, and illumination. The proposed descriptor incorporate polynomials of various degrees to ...
Effect of hexagonal on the in-plane crushing behaviour of plain weave composite hexagonal quadruple ring system
(
Taylor and Francis Ltd.
, 2019 , Article)
In this study, an experimental investigation into the crushing behaviour of one dimensional composite hexagonal cellular structure between two plates has been carried out. The materials have been used to accomplish the ...
Performance of Greenhouses in The Arabian Gulf
(
Qatar University
, 1990 , Article)
This work is devoted to the gaining of insight into the operation of environmentally controlled greenhouse in hot and humid climates. Field data inside and outside the greenhouse, namely: solar radiation, dry and wet bulb ...
Solidification Of Steel Billets In Continuous Casting
(
Qatar University
, 1991 , Article)
For practical operation, it is necessary to know how the solidification of liquid steel progresses i.e. when and where a strand has completely solidified. Decisions on, the casting speed, the spray water flow rates and ...
Performance Evaluation Of A Msf Desalination Plant In Qatar
(
Qatar University
, 1992 , Article)
In this paper, an assessment of the performance of one of the multistage flash (MSF) desalination units operating in conjunction with the gas-turbine cogenera-tion power plant in Qatar is carried out under different operating ...
Study of A Time Dependent Double -Diffusive Salinity Problem
(
Qatar University
, 1989 , Article)
The time-dependent, double diffusive stability problem for a horizontal layer of salty water bounded by two rigid isothermal surfaces is analyzed using a linear perturbation technique. Initially, the layer is subjected to ...
