The main goal of this thesis is to discuss the Beaming of identiflability of distributed parameter system and to find conditions that will make the parameters identifiable. This work is divided into two parts. The first part deals with theoretical identifiability, while the second part deals with identifiability under approximation.
Abstract: This study tries to reach an approach for hemorrhage control process based on using Nd:YAG laser, in order to reduce the time needed for coagulation. The Nd:YAG laser with its different powers and modes is one of the most widely used lasers in medical applications . The research shows that this laser type is a powerful and useful method for haemostaisis, one of the most important medical applications of laser with no mentioned side effects. The work in this study describes the improvement of haemostaisis time by using Nd:YAG laser.
Abstract: The data security can be enhanced by using IPSec/VPN policies. In this work the task of encryption are integrated to provide the higher level of security services. The work has focused on the tunnel technique to be the core of the proposed VPN. A tunnel is a way to transfer data that can be enclosed by the corresponding tunnel protocol (IPSec tunnel mode). Raw socket software programming interface has been implemented to send and receive IP datagrams throughput the network.
Several types of laser are used in laser angioplasty and in experimental works to study the effects of laser on blood vessel and blood clot. They differ from each other by a lot of properties mainly in wavelength, energy of the laser and pulse duration. Argon laser, CO2 laser and Nd: YAG laser are used widely in the ablation of atheroma and in the recanalization of occluded vessels. In this study Argon laser (488 nm- 514 nm), Co2 laser (10.
During the last few decades, the field of medical image processing has been closely related to neural network methodologies and their applications, especially after the vast successful researches in this field and the advanced newly formulated algorithms as well as the need for accuracy and intelligence in assessing of the medical images in critical diagnosis and oncology care cases.
Fault-tolerance technology has become an important branch in computer systems, and is widely used in many other fields. Fault-tolerance schemes can be used to increase the Availability and Reliability of network service systems. This thesis implemented a Fault-Tolerance Web server system that supports software and hardware failure bypassing, depending on the Dual-Server Hot-Standby principle, where an efficient transparent fail-over scheme is used to provide fault-tolerant network service.
