Carpal tunnel syndrome (CTS) is a neuropathic condition commonly caused by the entrapment of the median nerve. The most common complaint presented by the CTS patients is pricking sensation, numbness, pins and needles, burning sensation as well as in the hand and sometimes the arm/s distribution of the affected side. The patients with CTS usually complain of nocturnal periodic sleep disruption caused by the pain discomfort. In my dissertation, I explore the extent to which the CTS pain influences sleep architecture using neurophysiological measurements like an overnight electroencephalogram (EEG), conduction tests as well as subjective questionnaires. I initially conducted a pilot research study on 33 patients with CTS using subjective questionnaires. The CTS patients reported sleep disturbance. I also demonstrated that they (patients) had a minimal mood and psychological disturbance. I was prompted therefore to investigate the influence of the CTS pain on the sleep architecture using more objective empirical instruments like the polysomnogram as well as subjective measurements such as Beck Depression Inventory, Profile of mood states, Visual analogue scales as well as the McGill pain questionnaire to further investigate changes. The patients were required to spend four nights in the sleep laboratory divided into two nights before surgery and two nights at least two to six weeks following the CTS surgery. The CTS surgery is commonly used to release the compression of the median nerve at the wrist. The changes in subjective and objective variables were compared before and after CTS surgery. The age and gender-matched control group was introduced into the research study. The control group was required to spend the same number of nights in the sleep laboratory as the CTS group. The control group was also going to have a non-painful procedure of the same magnitude as the experimental subjects. The conclusion I reached on this study was that the CTS patients reported poor sleep quality. I also demonstrated that there were not many changes in the polysomnogram and that there were minimum changes shown on the nerve conduction studies variables as might have been expected based on the severity of the carpal tunnel syndrome. Another important finding was that there was a relationship between pain and depressive mood in CTS patients. The removal of pain in CTS patients showed that there was a subsequent subjective improvement in mood and psychological status and no significant improvement in subjective measurements. There were no significant changes noted on the control subjects who were pain-free.

Since the introduction of networks, they have been used amongst home users, companies and organizations and most damage on the network is due to inappropriate security configurations. To secure networks, a protocol suite can be used to encrypt and authenticate all IP packets of a session. Therefore, this report will include the advantages and possible solution of some techniques used to offer increased network security such as scalability and data confidentiality. Captures of traffic sent using the two security techniques, IPSec/VPN and GRE-Tunnel will be monitored. The objective behind this project is to configure a network with these two different tunneling techniques and compare the security and network performance. The report also describes the security problems encountered by networks such as the ignorance of network users, vulnerabilities and the security of the devices.IPSecis a standard security protocol solution for TCP/IP, and it provides security through authentication, encryption and data integrity. GRE encapsulates packets and create a logical hub-and spoke topology of virtual point-to-point connections. The Jperf-tool is used to measure network performance and show specific details while another tool, Wireshark is used to analyze the information captured during transmission of data sent using IPSEC and GRE. The comparison further finds that IPSec-tunnel technique makes data transfers very secure but causes network performance disadvantages in comparison to a GRE solution.
