Today’s society is highly dependent on functional and secure digital resources, to protect users and to deliver different kinds of services. To achieve this, it is important to evaluate the security of such resources, to find vulnerabilities and handle them before they are exploited. This study aimed to see if web applications based on C#, .NET and Episerver had vulnerabilities, by performing different penetration tests and a security audit. The penetration tests utilized were SQL injection, Cross Site Scripting, HTTP request tampering and Directory Traversal attacks. These attacks were performed using Kali Linux and the Burp Suite tool on a specific web application. The results showed that the web application could withstand the penetration tests without disclosing any personal or sensitive information. However, the web application returned many different types of HTTP error status codes, which could potentially reveal areas of interest to a hacker. Furthermore, the security audit showed that it was possible to access the admin page of the web application with nothing more than a username and password. It was also found that having access to the URL of a user’s invoice file was all that was needed to access it. / Dagens samhälle är starkt beroende av funktionella och säkra digitala resurser, för att skydda användare och för att leverera olika typer av tjänster. För att uppnå detta är det viktigt att utvärdera säkerheten för sådana resurser för att hitta sårbarheter och hantera dem innan de utnyttjas. Denna studie syftar till att se om webapplikationer baserade på C#, .NET och Episerver har sårbarheter, genom att utföra olika penetrationstester och genom att göra en säkerhetsgranskning. Penetrationstesterna som användes var SQL-injektion, Cross Site Scripting, HTTP-förfrågningsmanipulering och Directory Traversal-attacker. Dessa attacker utfördes med Kali Linux och Burp Suite-verktygen på en specifik webbapplikation. Resultaten visade att webbapplikationen klarade penetrationstesterna utan att avslöja någon personlig eller känslig information. Webbapplikationen returnerade dock många olika typer av HTTP-felstatuskoder, som potentiellt kan avslöja områden av intresse för en hackare. Vidare visade säkerhetsgranskningen att det var möjligt att komma åt webbapplikationens adminsida med inget annat än ett användarnamn och lösenord. Det visade sig också att allt som behövdes för att komma åt en användares fakturafiler var webbadressen.

Cam phasers allow improvements to the efficiency and emissions of internal combustion engines. The usage of hydraulic vane type cam phasers for heavy-duty applications have shown problems with oscillations during testing at Scania CV. To investigate the root cause of the oscillations a detailed 1-d simulation model has been created. The 1-d simulation model was calibrated and compared against measurements of a cam phaser system mounted on a physical engine. The 1-d simulation model of the cam phaser system was shown to be able to reproduce the oscillatory behavior seen in engine tests. But there are some concerns regarding the model's reliability, due to its dependence on the integration time step. It was determined that free air in the phaser chambers is causing the excessive oscillations. The source of the free air present in physical phasers are not yet fully understood, but the movement of the phaser control valve, opening and closing of the phaser chamber vents, in conjunction with motion of the phase oscillations has a significant effect on the phaser's chamber pressure, resulting in reduce pressures. The reduced pressures result in air being sucked in to the phaser, form both the oil control valve vent and external chamber leakages. Another potential sources of free air is dissolved air in the oil supply being released due to low pressures from oil pressure fluctuations. A potential solution to increase the stability of the phaser is to reduce the sources of air, by having an oil accumulator at the vent, limiting leakage, having a high and steady oil supply pressure, modifying the oil control valve ports to have a more gradual initial opening area and controlling the oil control valve appropriately. How to implement these implementations and evaluate them are left as future work. Potential improvements to get rid of the 1-d simulation model's dependence on the time step, increasing the model's reliability, are discussed, but not tested.

This report describes my work with developing a game for a gaming platform that enables hybrids between board games and computer games. My ambition has been to develop a game that takes advantage of the novel possibilities that this platform permits. Among those are to operate with a combination of the computer game traits of complexity in the games and ease of playing; as well as the board game / card game traits of combining social dynamics around a game session with ability to keep information hidden from other players. This is accomplished by a combination of mobile phones and a computer connected to the Internet. The screen of the computer will serve as board and the phones will display cards and other private information to the players, as well as functioning as the players' means for interaction with the game. The game developed, Wind Bugs, takes advantage of the complexity of game states that a computer easily can handle. Effort has been put into finding mechanics with a level of complexity while still implementing them in way that makes them both playable and enjoyable. Rather than focusing on immersion, which has become common in the design of computer games, hopes are that games for this platform, including the game developed in this project, will give room to social dynamics among the players. Though operating with the use of mobile phones, the platform will not support "mobile gaming"; the proposed setting is a group of players surrounding a big screen.

Jack Heggie's 2011 song cycle Pieces of 9/11: Memories from Houston is a collection of six songs with texts by Gene Scheer. Commissioned by the Houston Grand Opera, it was premiered on September 11, 2011 at the Rothko Chapel in Houston, TX. Based on interviews with people from Houston by Gene Scheer, this cycle tells stories and experiences by those affected by the September 11, 2001 terrorist attacks on the World Trade Center in New York City, The Pentagon in Washington DC, and those aboard United Flight 93 that crashed in Shanksville, Pennsylvania. Scheer's acclaimed storytelling in each song is beautifully set to varying styles of music composed by Heggie, with the familiar theme from Bach's Cello Suite No. 1 in G Major, BWV 1007 woven throughout the cycle. This document is an in-depth look at the cycle to be used by vocal coaches and singers in their preparation and performance. The first introductory chapter is followed by a chapter detailing the song cycle from concept to fruition. The third chapter concentrates on the uses of Bach's Cello Suite No. 1 in G Major, BWV 1007. The fourth chapter discusses the six individual songs first by discussing the background of each text, then an analysis of the music, and concluding with the relevance to 9/11. Chapter 5 includes performance notes, gathered from interviews with Heggie, Scheer, and one of the girl sopranos, Ashley Traughber. Appendices include a timeline of events on 9/11, the three interviews, a chronology of Jake Heggie's vocal works to date, and the author's personal 9/11 story as I was just a few blocks away from the World Trade Center on 9/11.
