Sensor networks have been used extensively in many applications to monitor different phenomena in the monitored field. These networks have to continue working without interruption for better monitoring as well as to satisfy the applications requirements ...

Qur'an, AL-Sunnah and Islamic traditional books are the rich resources for Muslims that used as the sole authoritative source of knowledge, wisdom and law. The challenge for computer scientists is to extract and represent these knowledge, wisdom and law in computer systems, this knowledge is directed or underlying, therefore, to build an intelligent systems which can answer any question with knowledge from Quran, Al-Sunnah and other Islamic books, special techniques for mining data must be used to deal with this issue, which can help society, both Muslim and non-Muslim, to understand and appreciate the Islamic religion, this paper attempts to understand how the new techniques in data mining can extract Islamic knowledge from its resources, and represent these knowledge in meaningful for the user. Moreover, this study concentrates on Hadith as knowledge resource, and proposes approach to classify Hadith to its categories using supervised learning classification. The finding of this study shows that there are several ways to extract knowledge from Hadith depending on the goal of the knowledge.

Abstract We propose a novel approach for the collaborative enforcement of security policies in distributed systems that is based on the dynamic (re-) deployment of multiple PDPs. The policies enforced by the collaborating PDPs are analysed and decomposed from a system wide policy as present in current centralized approaches. The security policy is decomposed into sub-policies based on an object domain approach so the decisions are local to the object's domain. The classes of policies investigated are dynamic history-based access ...
