Resource-constrained mobile devices are becoming increasingly popular within distributed networks, but introduce a weak point of security. Existing protocols for distributed mobile device networks, such as SPKI/SDSI, are emerging standards and lack built-in confidentiality, mutual authorisation and mutual authentication. Our research addresses the above-mentioned security limitations of an exis...

Connections in an ATM network are made using virtual channel connections which can be either permanent (PVCC) or switched (SVCC). SVCC requires a signalling protocol which is being standardised by international standards organisations. Because of the cost eeectiveness of SVCCs over PVCCs for data communication in an ATM environment, a signii-cant amount of work has been carried out to determine...

As a recognised leader in the UPS industry, Chloride has long been known for anticipating market needs and developing benchmark solutions, particularly in terms of technology. To this extent Chloride has developed Trinergy; an intelligent modular solution designed to meet the highest standards of performance, serviceability, flexibility and scalability, while also incorporating maximum energy s...

background: the presence of heavy metals in dialysis water which enters patients’ body through haemodialysis can cause various problems such as acute poisoning, brain damage, osteoarthritis etc. therefore, applying the standards for dialysis water is indispensable. this study was carried out to determine the heavy metals of the enterence water of dialysis machines and its comparison with aami a...

Networking solutions, particularly wireless local area networks have revolutionized the technological advancement. Wireless Local Area Networks (WLANs) have gained a lot of popularity as they provide location-independent network access between computing devices. There are a number of access methods used in Wireless Networks among which DCF and PCF are the fundamental access methods. This paper ...

as a robot could be stable statically standing on three or more legs, a six legged walking robot can be highly flexible in movements and perform different missions without dealing with serious kinematic and dynamic problems. an experimental six legged walking robot with 18 degrees of freedom is studied and built in this paper. the kinematic and gait analysis formulations are demonstrated by an e...

nowadays, harmonization of regulations regarding the sanitary and phytosanitary measures and its advantages and disadvantages is one of the most controversial issues in international trade law. this issue has gain much attention, in particular, after adoption of the wto's agreement on the application of sanitary and phytosanitary measures (sps agreement) and its emphasis on harmonization of san...
