The shared memory systems should support parallelization at the computation (multiprocessor), communication (Network-on-Chip, NoC) and memory architecture levels to exploit the potential performance benefits. Such systems are facing the critical issues of memory consistency and coherence. Memory consistency issue arises due to the unconstrained operations which sometimes lead to the unexpected behavior of the systems. Memory consistency models are used to resolve this issue. Relaxed or weaker consistency models enforce less ordering constraints on the memory operations and exploit system...

Mathematics models real life phenomena to understand the underlying laws of nature governing them, more precisely. Ever changing physical phenomena are represented by differential equations. But this imposes condition that the changes itself are continuous and are taking place in a continuous domain. Whereas real situation, most of the times, are discrete in nature. These phenomena are present in almost everywhere but most commonly in Biology, Physics (classical and quantum), Geometry, Mathematical design and Finance etc. Difference equations provide a better choice to represent discrete...

In this book the authors have critically studied the Women Protection Bill 2006 (WPB, 2006) in the social and religious context and the future of higher education of females in Pakistan. The Women Protection Bill was enacted on Nov 15 2006 that replaced the Hadood Ordinance (HO 1979). The authors have compared the two bills. The major finding of the study is that the majority of the university female students and teachers feel that WPB, 2006 is an anti-Islamic bill. The study suggests that not only proper orientation of the bill needed to be given but also female, teachers and students should...

Hijab is dignity of Muslim woman. Pakistan is one of the major Islamic country and in Pakistan a large proportion of females wear hijab. In our study we have to try the advantages and disadvantages to wear hijab and also to see the Islamic point of view in this regard. In this study we have try to analysis the different aspects of hijab in Pakistan. This book is helpful for the researchers who are interested to this type of study.

Rice (Oryza Sativa. L) is staple food and in Pakistan 5547 thousand tons of area is under rice cultivation. The productivity of rice can be enhanced by use of pesticides but once these toxic chemicals are applied to rice crop some of their residues remain on crops. The presence of these pesticides can pose risk to humans and also to the environment either directly or indirectly. So the present study was conducted to estimate the residual level of some selected organochlorine pesticides (OCPs) in rice grains and straw samples collected from different areas of Punjab, Pakistan. According to...
