MANET or mobile adhoc network is infrastructure less network which does not require any centralized support. Equipped with CSMA/CA (carrier sense multiple access with collision avoidance) transceivers, mobile nodes communicate via radio. As network topology always changes due to mobility of nodes, routing as well as routing protocol selection is qu

This study aims to optimise the operating conditions for the supercritical fluid extraction (SFE) of toxic elements from fish oil. The SFE operating parameters of pressure, temperature, CO2 flow rate and extraction time were optimised using a central composite design (CCD) of response surface methodology (RSM). High coefficients of determination (R

This paper presents simulation results on randomness test of a cryptographic one-to-many reversible mapping between user space and the IPv6 address space. A one-to-many reversible mapping mechanism is developed which may be embedded into a DHCPv6 (Dynamic Host Configuration Protocol for IPv6) server in the stateful mode within an enterprise local a

We demonstrate an efficient fiber laser operating at 1901.6 nm using a new Thulium Bismuth co-doped fiber (TBF) under 802 nm pumping. The TBF was fabricated using modified chemical vapor deposition process associated with optimized solution doping techniques. The TBF lasers at 1901.6 nm are obtained at a noticeably low threshold pump power of 75–

A mobile ad-hoc network (MANET) is a self-configuring infrastructure-less network of mobile devices connected by wireless links where each node or mobile device is independent to move in any desired direction and thus the links keep moving from one node to another. In such a network, the mobile nodes are equipped with CSMA/CA (carrier sense multipl

This paper presents a novel mechanism of cryptographic one-to-many reversible mapping between two domains and it's applications. One-to-many reversible mapping is a one-to-many mapping in which the relations can be reversible. Cryptographic one-to-many reversible mapping is that the development of one-to-many mapping is performed based on pseud

إن تعليم اللغة لأغراض خاصة مجال تدخل عليه تطورات مستمرة تتناسق مع حاجات المتعلم التي تسير مع التطورات في مجال تخصصٍ. وتستلزم هذه الحالة مسايرة الكتب المقررة في هذا المجال مع تلك التطورات. ومن أ

Recent technological advancements in sensors and conditioning electronics are finding applications in many areas including non-contact monitoring in remote areas, in the medical field and better automation in the automotive industry. Such electronics need power sources both through wired and wireless means. Given this, inductive coupling is the mos

Wireless Sensor Networks (WSN) are implemented in wide range of applications and one of these important applications is the localization and real-time tracking. The accuracy, cost, and power consumption are the most parameter for any proposed technique. Localization in indoor environment is more challenging than outdoor since the known Global Posit

Chronic hepatitis B infection is associated with dysfunction of cell- mediated immunity. Little is known about the changes of immune response during chronic hepatitis B infection, particularly in correlation between sequential alterations in peripheral blood immune cells population and hepatitis B surface antigen (HBsAg). AIM: to examine the dynami
