In this extraordinary and beautifully-written autobiography, Asad
tells of his initial rejection of all institutional religions, his
entree into Taoism, his fascinating travels as a diplomat, and
finally his embrace of Islam.

A Sourcebook of Themes from the Holy Qur'an. It offers 265
selections of verses, presented in a fresh contemporary translation
of high literary quality, with accompanying interpretations by
leading Muslim intellectuals, including Muhammad Asad, Yusuf Ali,
and others. Formerly titled The Vision of the Qur'an.
One hundred cases of various types of angina pectoris in two
hospitals of Narowal during September 2008 to January 2009 had been
analyzed to determine the relative occurrence and incidence of
angina pectoris, and effects of various risk factors. The analysis
shows that silent angina pectoris were more prevalent (79%,
n=79/100), and painful angina pectoris were less prevalent (21%,
n=21/100). About 56% cases reported, belong to the age class 41-60
years with a higher incidence of silent angina pectoris. Angina
pectoris is more prevalent in females (65.00%) as compared to males
(35.00%). In relation to various risk factors, silent angina
pectoris is the most prevalent. The mortality rate in this sample
due to angina pectoris is 12.00%.
Adaptive ¬ltering algorithms have been proposed to improve the
performance in terms of their steady-state error and convergence
rate. They have also been developed to counter the e¬ects of
measurement noise characterised as white Gaussian. The Least Mean
Square (LMS) algorithm has been by far the most important in terms
of its simplicity and range of applications. Thus it has been a
centre point of extensive research. In particular, the time-varying
step-size models of LMS have contributed immensely in the
performance enhancement of LMS algorithm. By comparison the Least
Mean Fourth (LMF) algorithm that gives better convergence rate in
non-Gaussian noise environment has not been researched in its full
spectrum. The aim of this work is to exploit the research in LMS
algorithm particularly in the model of time-varying step-size
parameter and extend it to the LMF. We have developed a variable
step-size LMF algorithm with the aim to achieve better performance
than the traditional LMF and retain its inherent dominance over the
LMF in non-Gaussian noise environments.
In this work we tread upon the classical two-dimensional X-ray
tomography problem modeled by the Radon transform. We have focused
on the problem of simultaneously inverting the Radon transform and
segmenting the density distribution into homogeneous regions
directly from the sinogram data i.e. from the attenuation data of
X-rays passing through the body. We have used modified Mumford-Shah
model for piecewise constant densities. The segmenting curves are
described by a suitable level-set function and the problem of
optimal adjustment of the curves to the actual contours of objects
in the density distribution is achieved combining shape sensitivity
techniques with level-set based transport of geometrical objects.
The novel contribution of this work is the use of second order
shape sensitivity analysis to construct a Newton-type descend
direction for the solution of the resulting shape optimization
problem. To construct an algorithm which performs the
reconstruction and segmentation simultaneously from the measured
data was the prime motivation of this work.
