Queuing systems are important parts of our daily lives and to keep their operations at an efficient level they need to be monitored by using queuing Performance Metrics, such as average queue lengths and average waiting times. On the other hand queue lengths and waiting times are generally random variables and their distributions depend on different properties like arrival rates, service times, number of servers. We focused on detecting the change in service rates in this report. Therefore, we monitored queues by using Cumulative Sum(CUSUM) charts based on likelihood ratios and compared the Average Run Length values of different service rates.

<p><p>Ericsson is a global provider of telecommunications systems equipment and related services for mobile and fixed network operators. </p><p>3Gsim is a tool used by Ericsson in tests of the 3G RNC node.</p><p>In order to validate the tests, statistics are constantly gathered within 3Gsim and users can use telnet to access the statistics using some system specific 3Gsim commands.</p><p>The statistics can be retrieved but is unstructured for the human eye and needs parsing and arranging to be readable. </p><p>The statistics handler that is implemented during this thesis provides a possibility for users of 3Gsim to present information that favors their personal interest.</p><p>The implementation can produce one prototype output document which contains the most common statistics needed by the 3Gsim user. A main focus of this final thesis has been to simplify content and format control for the user as much as possible.</p><p>Presenting and structuring information now comes down to simple text editing and rid the user of the time consuming work of updating and recompiling the entire application.</p><p>Earlier, scripts written in Perl, an iterative oriented language, were used for presenting the statistics. These scripts were often difficult to comprehend since there were many different authors with inadequate experience and knowledge.</p><p>The new statistics handler has been written in Java, a high-level object-oriented language which should better suite the users and developers of 3Gsim. </p></p>

<p>The subject of this thesis is to formulate effective energy expressions (Hamiltonians) of proteins and protein related systems. By use of equilibrium statistical mechanics we calculate thermodynamical functions, whereupon we compare the results from theory with experimental data. Papers 1-7 and 10-12 concern this problem. In addition, Paper 8 (P8) and Paper 9 (P9) are attached. Both these papers were finalized during the Ph.D. study. However, they are not related to proteins. </p> / Papers II, III, V, VII, VIII, XI and XII are reprinted with kind permission of Elsevier, sciencedirect.com Papers VI and IX are reprinted with kind permission of the American Physical Society.
