Identifiering av parametrar för tillståndsbedömning av en vattenkraftstation
The report begins with a general inventory of possible technical faults in a hydropower plant and of possible fault indicating measurements. Then an investigation is made concerning a few different faults. Based on this investigation a choice on seal box condition and water leakage is made as problem for a more thorough examination, in which it is concluded that the turbine water leakage is larger when the turbine is put into operation. The examination ultimately results in a computer alarm for faults related to the seal box. Finally a few things are mentioned about flow measurement and pressure measurement in relation to the project as a whole..
Alarm på bryggan : trygghet och irritation
Arbetet på fartygsbryggor består till en stor del av kontrolluppgifter. Operatörerna, bryggteamet, har därför kontroll- och alarmsystem till förfogande. Samspelet mellan människa och system beror delvis på användarens kunskaper och erfarenheter och delvis på bryggdesign och teknikens användarvänlighet. Arbetets ämne är hanteringen av alarm och alarmsystem på fartygsbryggor. Syftet var att undersöka om det finns strategier för detta och i så fall att belysa hur dessa strategier ser ut. Därför undersöktes sju styrmäns erfarenheter med kvalitativa metoder, med halvstrukturerade intervjuer och med innehållsanalys.
Datorbaserad examination: En studie om användarhinder och systemacceptans bland lärare
The aim of this thesis is to examine how teachers use computer based assessment in their work and what user barriers they experience while working with computer based assessments. The result of the thesis is meant to provide an understanding of which factors affect the use of computer based assessments and how a company who provide computer based assessments applications can increase the rate of use amongst teachers.To investigate this, the author examined a company in Sweden who provide a computer based assessment application for both universities and high schools. The study was carried out at two different schools, a university and a high school, both located in Stockholm. In total nine teachers were interviewed. The author also conducted observations at the company whose computer based assessment application was examined.The author?s findings suggest that a lack of functions within the application and lack of costumer support from the company all negatively impacted the teacher?s use of the application.

En laptop till varje elev : en studie om gymnasieskolans satsning på datorer i undervisningen
The aim of this study is to highlight the computer as a learning resource in the education and give us knowledge about how the students uses the computer in year one in a selected High School where one computer per student were introduced in autumn 2011. The aim is also to contribute to the discussion about how the computer can become a natural learning resource for all students in all subjects, including the students in need of special support.How are the High School students using the computer?Are there differences in computer use, whether the student is in academic or vocational program?Are there differences in computer use between boys and girls?Do the student experience that the digital competence is increasing together with if they experience the computer as aid?In what degree do the teachers encourage the students to use the computer?How much do the students use the computer to learn mathematic?The study is based on a survey of all students in year one in a municipal High School.The result of the study is showing that the students first of all use the computer to play music, surf the Internet and to be logged in on social media (eg. Facebook). The students have learned to use the computer for the tasks they need, although the teachers don?t encourage the students to use the computer in any higher means, not in mathematics and not in other subjects.
Installation av övervakningssytem ombord på fartyget M/S Andromeda
This report is regarding an electrical installation of an alarm system on a post fishingboat called Andromeda. The background of the installation was an earlier andinadequate alarm system that led to a motor failure. The ship was taken out of serviceand was sold to Björn Magndahl who rebuilt it to a yacht.The project was conducted partly by developing the existing systems, partly bydocumenting the work by means of electrical blue prints. Except the alarm systems, aninstallation of the frequency control unit for the bow thruster was installed.The installation was working fine and the outcome of the documentation was handedover in a form of a binder during the test drive of the systems and the assignment wasapproved..

EAS-tagg med fuktsensor : Design och utvärdering av EAS-alarmteknologi för fuktdetektering
Electronic article surveillance (EAS) is widely used in shops and libraries together with an RF-tag attached to the goods or books in order to prevent shoplifting. By implementing the addition of a moisture sensor to the RF-tag, other functions become possible, including the ability to use as an alarm with regards to frozen goods, which have been shipped but which have melted and have, subsequently, refrozen. In- relation to care for the elderly, one time-consuming step involves checking whether there is the necessity for a change of diaper and this can, instead, be based on an RF-tag with an EAS-system alarm. A preliminary investigation was made using the moisture sensors, which involved how the resistance changes when liquid and/or heat is applied. A simulation of the LCCR circuit (RF-tag with the sensor) was conducted in order to determine how the resonance frequency changes for different resistances levels.
Trygg med trygghetslarm? : en kvalitativ studie av några ålderspensionärers erfarenheter och upplevelser av trygghetslarm
The purpose of this study was to depict some elderly people?s experiences of personal safety alarms. Furthermore, the aim was to look into whether there is any difference in experience between men and women and depending on their level of care. Using a qualitative method, semi-structured interviews were carried out with eight elderly people; six women and two men. The main questions of the study were: How do the elderly people experience the practical use of personal safety alarms? In what ways, if any, do the elderly people experience that the personal safety alarm has changed their daily life? In what ways do the elderly people experience that the personal safety alarm effects their ability to stay in their own home? A cognitive perspective was mainly used to analyze the results.

Dataspelsarvet - klassiker och kanonisering
This master thesis deals with computer game classics and a possible computer game canon. It looks closer at four computer game genres - adventure, RPG, action and strategy - in order to discern which games are considered classics and what characterizes them. To answer the first question a quantitative research method was used. 675 computer game reviews from 5 Internetsites were examined in order to see which games are mentioned most often in this context and therefore might be considered classics. To answer the second question a qualitative research method was used.
Ett flervariabelt feldetekteringssystem för övervakning av bärlagertemperaturen i vattenkraftturbiner
The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute was developed to estimate the bearing temperature. Then a detector for detection of change in bearing temperature based on the CUSUM-algorithm was designed. Since the amount of data was very small the developed model was too uncertain to be used in a working system.The designed fault detection system showed to work well for the available data.
