The purpose of this master thesis is to implement and validate a Power System Stabilizer (PSS) to a generator at Trängslet hydropower station in Dalarna, Sweden. Problems with local rotor oscillations can occur at the hydropower station when power is transferred on a new power line (130 kV) from Northern to Southern part of Dalarna. To ensure good operation properties on this power line Fortum Generation AB and Fortum Distribution AB wants to activate a PSS on a generator.There have been investigations in which situations and what equipment that contributes to rotor oscillations. When this is known the PSS is tuned to damp these oscillations by choosing a good set of parameters. The most important parameters for good performance are to choose amount of gain and phase compensation.

Studien använder ett explicit test och jämför ungdomar (14-16 år) och vuxna gällande deras riskbedömning av brott, attityder kring brott och moralnivå. Dessa faktorer förväntas ha ett samband med varandra och kan ge en förklaring till varför ungdomar begår fler brott per capita än vuxna (Ahlberg, 1996). Samplet som utgjorde ungdomsgruppen (N=101) togs från fyra högstadier och vuxensamplet (N=101) bestod av studerande vid Komvux. Testet var ett egenkonstruerat frågeformulär och visade på flera signifikanta skillnader mellan vuxengruppen och ungdomsgruppen där vuxengruppen rapporterade högre riskbedömning, strängare attityder kring brott samt en generellt högre moralnivå. Studiens resultat stödjer tidigare forskning som visat på en diskrepans mellan ungdomars och vuxnas riskbedömning.

Den 1 januari 2005 trädde IASB: s redovisningsstandarder i kraft. Dessa standarder skall tillämpas av alla svenska börsnoterade koncerner. En stor förändring, i förhållande till svensk redovisningspraxis, som dessa regler förde med sig var värderingen och redovisningen av goodwill. Tidigare ansågs goodwill som en restpost som inte behövde motiveras i någon större utsträckning. IASB har sett till att skapa en mer konkret syn på goodwillvärdet.

Syfte och frågeställningarHuvudsyftet med denna studie var att se om ett vertikalhopp eller ett trippelhopp uppvisade större känslighet att identifiera skillnader mellan opererat och icke-opererat ben i jämförelse med ett horisontalhopp hos individer som genomgått främre korsbands(ACL)-rekonstruktion.Studien syftade även till att undersöka om individens kön påverkade resultatet och om prestationen på de olika hoppen hade ett samband med isokinetisk benstyrka respektive det knäspecifika instrumentet KOOS, The Knee injury and Osteoarthritis Outcome Score.Metod17 försökspersoner, 9 män och 8 kvinnor (medelålder 28 år) deltog i studien. De hade alla genomgått primär unilateral ACL-rekonstruktion i genomsnitt 7 månader tidigare. Vid ett och samma mättillfälle utfördes ett isokinetiskt styrketest samt tre funktionella hopp: vertikalhopp (?Jump and Reach?), trippelhopp samt horisontalhopp. KOOS fylldes i av försökspersonerna runt samma tidpunkt (nätbaserat frågeformulär för utvärdering av patientens upplevelse av sitt knä och knärelaterade besvär).ResultatVertikalhoppet uppvisade en högre sensitivitet i jämförelse med horisontalhoppet vid test 7 månader efter ACL-rekonstruktion.Gällande de absoluta värdena (opererat ben) uppvisade både vertikalhoppet som trippelhoppet ett statistiskt samband med explosiv quadricepsstyrka (240grader/sekund), r=0,75 respektive r=0,73.Inget samband kunde ses mellan hopp och resultatet på KOOS.Inga könsskillnader hittades.SlutsatsResultaten visar att vertikalhoppet är ett mer sensitivt test för att identifiera funktionella nedsättningar i ACL-rekonstruerat knä i jämförelse med horisontalhoppet som ofta används som ?gold standard? i forskning och i den kliniska vardagen.En enkel och billig testmetod för vertikalhoppet, ?Jump and Reach? som användes i denna studie visar liknande resultat på sensitiviteten i jämförelse med datoriserade mätmetoder som är dyra och ofta inte tillgängliga i sjukgymnastens kliniska vardag..

The purpose of this MSc thesis is to examine the retrieval effectiveness of two Web search engines with queries from the academic discipline of Classical Studies. The two search engines are chosen to represent two different types Google as a broad general search engine and Argos as a specialised search engine for the subject of Classical Studies. The search engines are compared for precision among the first twenty results returned for thirty queries. In order to avoid bias in the study, the queries are based on real users' information needs. Due to the subjective character of the concept of relevance, the study is performed with five different experiments with five different definitions of relevance.

The purpose of this paper was to study how the death is described in some books for children and how the books may affect the readers. I chose five books where the leading character was a child who lost a close relative like a parent or a sibling. I asked the book questions like you would do at an interwiew.The main questions were:· What do the children think about the death?· How does the child react when it finds out that a parent or a sibling is dead?· What does the child think about seeing the dead person and how does it react at the funeral?· From what or whom do they find the strength to move on?· What support does the child have from people in the surroundings?· How may the books affect the readers?The results showed that the books give you an image close to the reality. The children had different ways to mourn.

Staphylococcus aureus is the most clinically important Staphylococcus species and is associated with high mortality in patients with positive blood cultures. S. aureus bacteria may cause a variety of disease manifestations ranging from minor skin infections to life-threatening conditions such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome (TSS) and sepsis. This microorganism belonging to the gram positive cocci may also be part of the normal flora. In Sweden, penicillinase-stable penicillins are the primary alternatives to treat S.

Tal är det akustiska resultatet av rörelser i talapparaten med avsikt att förmedla ett språkligt budskap (Kent, 2000). Oralmotorisk funktion är en grundläggande förutsättning för talkommunikation (Sjögreen & Lohmander, 2008). Om tal- eller oralmotoriska problem uppstår kan en tal- eller oralmotorisk diagnos ställs utifrån en utredning över dessa funktioner (McAllister, 2008). Nordiskt Orofacialt Test ? Screening (NOT-S) är ett screeningmaterial som testar den oro-faciala funktionen (Bakke, Bergendal, McAllister, Sjögreen & Åsten, 2007).

The purpose with this final assignment is to find out how the old and the new regulations about Goodwill affect the Swedish companies, how their results and value of Goodwill changed since the regulation from IFRS took place. We will attempt to find out if the companies are better of with a yearly write-off or an impairment test every year to see if a write-down is necessary..

Benthic diatoms are used in Sweden for monitoring water quality in run-ning water; the method is also frequently used in other countries in Europe. One of the problems of the diatom method is the need for sedimentation of the fresh sample, to be able to decant the over standing water and add alco-hol as a preservations solution. To my knowledge, no results have been published about how long the settling time must be to ensure that the ben-thic diatoms really have settled down to avoid a loss of the diatoms when decanting the over standing water. The aim of my investigation was to improve the Swedish method where the benthic diatoms are used for water quality monitoring. I wanted to find out the appropriate time necessary to wait until all diatoms have settled down before decanting the over standing water. First, fresh benthic diatom samples were taken in the river Fyrisån and the lake Mälaren on different days. After arriving in the laboratory, I waited three different times (30 min, 60 and 180 min) for the diatoms to settle.

The purpose of this master thesis is to create, test and evaluate an analytical instrument for children?s library environment based on a theoretical framework consisting of Howard Gardner?s theory of multiple intelligences and Thomas Armstrong?s pedagogical application of the original seven intelligences. We wanted to investigate whether the environment in Rum för barn stimulated all of children?s different intelligences. We also wanted to identify possibilities and liabilities within the analytical instrument.

Personal branding is a common phenomenon within the Swedish business world, although less applied on the competitive and fast paced music industry. In order to strengthen Swedish artists' personal brands and to ensure congruence between the artists' presented identities and the target audiences' perceived images, we have developed a model, containing of seven essential factors. The seven dimensions authenticity, credibility, certainty, openness, availability, awareness and timeliness help improve strength when communicating brand identity, as well as minimizing potential discrepancy between identity and image. This report examines the brand strategies within the Swedish music industry through a case study of Sweden's largest pop star, Eric Saade, where Team Saade's communicated identity is compared to the targets audience's perceived image of Saade. Overall, Saade's personal brand has a high level of congruence, except from the clarity dimension, where his words are considered differing from his actions.

Cykelstölder är ett stort problem i dagens samhälle. I Sverige polisanmäldes 65 700 cykelstölder under 2011. De cykellås som finns på marknaden kan på ett eller annat sätt brytas upp och efter det är cykeln fullt brukbar. Examensarbetets uppdragsgivare hade idéer om ett nytt cykellås som förhindrade cykelns brukbarhet efter uppbrytning av låset. Idén ledde till ett samarbete med uppdragsgivaren, mig och teknikkonsultföretaget, Cross Design.

Tree fiber lengths controls properties like strength and smoothness in paper and other wood products. For forest researchers it is of interest to be able to determine the fiber lengths in standing trees. Mo?rling et al. (2003), among others, have developed methods to estimate fiber length distributions in standing trees without damaging them.

The aims of the present study were to implement and evaluate a three-session Acceptance and Commitment Therapy (ACT) stress management intervention in a non-clinical group of university students (N = 25) and to investigate the importance of practice in an ACT-intervention. A design with pre-test and double post-test was chosen. A comparison was made between a nine-hour ACT-intervention containing practice for the participants, a two-hour lecture on ACT and stress management containing no practice for the participants and a control group. Psychological flexibility was assessed with Acceptance and Action Questionnaire-2 and mindfulness was measured with Kentucky Inventory of Mindfulness Skills. Perceived stress level was measured with Perceived Stress Scale.
