This degree project is dedicated to Waymark in Stockholm. Waymark is a consulting company where they, among other projects, develops a web application for one of the major banks in Sweden. Today the application is fully functional and deployed at the bank’s application server. Much of the work today is about maintenance but a lot of time goes to solve the bugs that the bank reports back to Waymark. One feature that was considered missing was to read the logs from the production environment in a smoothly manner. This functionality seemed appropriate for a degree project of ten weeks. The work is about solving this task and developing a prototype to be delivered to Waymark during the project. To solve this problem different log-analysis frameworks are tested to see how well they would fit. The web application is written in Java 7 and running on a WebSphere at the bank. The web layer is written in Wicket, jQuery and CSS3. Service layer running JPA2 and Google Guice used for dependency injection. For logging Log4J is used. The result turned out to be a built-in functionality in the application that manages the monitoring of the logs. Through the admin GUI, a specific log page can be opened where the user can read and filter the results to find the desired log messages. Configuration of Log4jJ has been done. Where on disk and how logs are stored has been discussed. Testing of the new functionality has been a high priority throughout the project. / Detta examensarbete är utfört åt Waymark i Stockholm. Waymark är ett IT-konsultbolag där bland annat en intern webbapplikation åt en storbank utvecklas. Applikationen är fullt fungerande och körs på bankens interna server. Idag förvaltar Waymark applikationen men ny funktionalitet införs konstant samtidigt som mycket arbete handlar om att lösa systemets buggar som banken rapporterar. En funktion som saknades var att kunna läsa loggarna från produktion på ett smidigt sätt. Denna funktionalitet ansågs som en passande uppgift för ett examensarbete på 10 veckor. Arbetet kretsar kring att utifrån den givna webbapplikationen undersöka hur denna funktionalitet skulle kunna se ut samt att utveckla fram en prototyp som levereras till Waymark innan projektets slut. I arbetet granskas logganalyserings ramverk för att se hur väl de skulle passa in i detta projekt. Webbapplikationen är skriven i Java 7 och körs på en WebSphere hos banken. Webblagret är skrivet i Wicket, jQuery och CSS3. Servicelagret kör JPA2 och Google Guice används för dependency injection. För loggning används Log4J. Resultatet blev en inbyggd funktionalitet i applikationen som sköter monitorering av loggarna. Via ett admin GUI kan en specifik loggsida öppnas där användaren kan söka och filtrera resultaten för att hitta önskade loggutskrifter. Konfiguration i Log4J har också genomförts. Var på disk och hur loggarna ska sparas har diskuterats. Testning av den nya funktionaliteten har haft hög prioritet genom hela projektet.

The aim of the theoretical part is a summary of commonly used graphics components for developing web applications in Java. In the introduction, theoretical part contains basic principles and terms related to the topic of work. Below is an overview of components, which is based mostly on documentation most widely used frameworks for building web applications. Individual components are divided into groups and there are descriptions and alternative names for each of them. Description of each component is aimed at its appearance as well as at routine use in practice. The practical part results from the list of components and categories created in the theoretical part. The first part is a description of the framework and its fundamental principles, especially creation of components. Each category and the components identified in the theoretical part are analyzed from the perspective of their applications in the Wicket framework. In the case of non-existing components in the framework are given options and mechanisms that replace the functionality of missing components.

Cricket umpiring is demanding. In today’s world where so much technology is available to television viewers, they expect perfect umpiring, forgetting that what they see on their television screens is not available to the umpires standing in the middle of the field making the decisions. This study aimed to examine cricket umpires on-field decisions during the 2007 ICC Cricket World Cup. Examining leg before wicket (LBW) and caught behind decisions, in particular. The researcher made use of a notational analysis program known as Umpirestat to collect the necessary data on each umpire. The umpires were examined in two groups Elite and International umpires (groupings defined by the ICC) and were compared to a base line in the form of Hawk-Eye for LBW decisions and TV replays for caught behind decisions. The umpire groups were compared to each other and then to the base line, an individual umpire comparison was then done within each grouping. The data was statistically analysed using percentages, chi squared and modelling for the Elite Umpires. For LBW decisions there was a difference of 2.02% between Elite and International umpires, showing a similarity between the two groups. The difference between Elite Umpires and Hawk-Eye was 18.83% and between International umpires and Hawk-Eye was 16.81%, showing difference between the three groups. It was found that there was a difference of 3.63% for caught behind decisions between Elite and International umpires, showing a similarity between the two groups. The difference between Elite Umpires and TV replays was 2.99% and between International umpires and TV replays there was 0.64%, showing similarities between the three groups. In conclusion, for LBW appeals there is a similarity between Elite and International umpire groupings however a difference exists between Hawk-Eye and both groupings of umpires. For the individual umpires LBW comparison the following was seen for the International umpires; no real conclusions could be drawn due to limited amounts of data collected on them. However, variances in individual performances were seen within the International umpire grouping. For Elite Umpires, it is clearly seen in the model that the umpires expected number of dismissals got closer together and almost group together at around four appeals. This indicates a strong consensus amongst umpires when dealing with four, five and six appeals during a match. This consensus is more pronounced for four and five appeals. In conclusion, for caught behind appeals there is a similarity between Elite and International umpires as well as a similarity between replays and both groups of umpires. For the individual umpires caught behind comparison the following was seen for the International umpires; as with the LBW results there was limited amount of data available for the caught behind results. Thus no real conclusions could be drawn for International umpire caught behind decisions, although when examining the percentage data, differences can be seen. For the individual umpires caught behind comparison the following was seen for the Elite Umpires, no consensus is seen between the umpires - they all appear to have different expected dismissals to one another.

The aim of this thesis is the analysis of selected frameworks for the development of modern web applications on the Java platform focusing on the front-end. The work is complemented by well-chosen source code examples that help the reader to create one's own view of the frameworks and it can also server as a tutorial. Introductory section focuses on the trends of modern web applications, especially on the front-end. It affects themes such as support for mobile devices, AJAX or responsive design of user interface. There are also introduced the latest technology on the front-end including HTML5, CSS3, jQuery library and dynamic language LESS whose main objective is the simplification, shortening and making cascading style sheets more dynamic. The output of this section: General LESS template is freely available and it can be applied to emerging projects. For the analysis there has been created static registration form on which there are applied frameworks Apache Wicket and Spring MVC with template engine Freemarker. In terms of analysis were chosen following points: the basic structure of the project, the application of static templates, external JavaScript / jQuery library, internalization, application of the form, submitting the form and validation of the input fields. The points were discussed in detail, especially in terms of implementation of both analysed frameworks. The outputs of the analysis are freely available structures of the projects and both of the resulting applications.

Den svenska vattenkraften står för nästan 50 % av landets elproduktion vilket gör dess konstruktioner till en viktig del av samhällets infrastruktur. För att ett vattenkraftverk ska fungera effektivt och säkert ställs höga krav på komponenternas funktion och kondition. I dagsläget genomförs därför rutinmässiga kontroller på, i och runt dessa anläggningar. För de aggregatnära inre vattenvägarna genomförs detta ca vart åttonde år i samband med reparationer av turbinerna, vilka då måste tömmas på vatten. För till- och utloppstunnlarna, som ofta är drivna i berg, finns det dock inte några sådana rutiner. Detta i kombination med att majoriteten av Sveriges vattenkraftverk har uppnått en ålder på över 50 år gör att branschen har börjat bli intresserade av att få kännedom om skicket på tunnlarna. Att genom-föra inspektioner genom att torrlägga dessa är dock en tidsödande process som kräver att kraftverket är avstängt under en lång tid och därmed ger en stor ekonomisk förlust för ägaren. Detta arbete har därför utförts med syfte att utvärdera till vilken grad inspektioner med undervattensfarkoster, ROV, kan användas som alternativ till inspektioner av inre vatten-vägar, både aggregatnära och i till- och utloppstunnlarna. En litteraturstudie har genomförts, om vattenkraftverk, vanliga skador, dagens inspektionsmetoder samt hur en ROV är uppbyggd och fungerar. Arbetet innefattar även tre praktiska moment bestående av deltagande på en inspektion av torrlagda aggregatnära inre vattenvägar och en inspektion med ROV i en 2,5 km lång utloppstunnel samt egna försök med inhyrd ROV för att undersöka vilka typer av betongskador som är möjliga att detektera. Resultatet från samtliga delar i arbetet pekar på att besiktningar med ROV kan övervägas för flera olika typer av inspektioner. För till- och utloppstunnlar är denna typ av inspektion många gånger den enda rimliga. För de aggregatnära inre vattenvägarna ger dagens inspektionsmetoder med torrläggning ett fullgott resultat, men ROV skulle kunna vara ett alternativ vid svårtillgängliga delar, t.ex. på grund av utformning eller stora läckage. / Swedish hydro power accounts for nearly 50 % of the country's electricity production which makes the constructions within this production system an important part of the societal infrastructure. To ensure safe and efficient operation of these hydroelectric power plants high demands are put on the components function and condition. Therefore, routine inspections are carried out inside and around these facilities. For the waterways directly connected to the power station, such as penstocks, wicket gates and draft tubes, these checkups are made about every eight years simultaneously as planned repairs of the turbine, when the waterways have to be emptied. For the head and trail race tunnels, which often are driven in bedrock, there are no such routines. This, in combination with the fact that the majority of the Swedish hydroelectric plants have attained the age of over 50 years, has led to an increased interest within the industry in ways to increase their knowledge about the condition of these water passageways. To conduct inspections by draining the tunnels is however a very time consuming process that requires the power plant to be turned off for a long time causing a major financial loss for the owner. The purpose of this master thesis is to assess the extent to which inspections with remotely operated vehicles, ROV, can be used as an alternative method for inspections of covered waterways, both those close to the power house and the head and tail race tunnels. A literature study of hydro power plants, common damages, current inspection methods and the construction and function of an ROV, has been conducted. The method also includes three practical activities, participation at inspections in drained waterways and at an ROV inspection of a 2.5 km tail race tunnel. Furthermore, tests with a rented ROV were carried out to investigate what type of concrete damages that are possible to detect using this method. The result from all parts in this thesis indicates that examinations by ROV can be considered for several types of inspections. For head and tail race tunnels, this type of inspection is often the only reasonable method. For the waterways directly connected to the power station, current inspection methods by draining show good result. But the ROV could here be an alternative in inaccessible areas, for instance due to waterway design or heavy leakage for instance.
