Kompensering av reaktiv effekt vid vindkraftverk
Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.
Utveckling av 300 kg HD Lightlift för belysning och liknande laster
The company LightLift Esystems AB manufactures patented motorized lift systems for the illumination of halls with high ceilings. The company wants a new design for singular heavy lights in order to be more competitive.This project consists of the development of the new design under the requirements and specifications imposed by the company. The new design must support lights up to 300kg and keep the overall dimensions as low as possible without modifying the driving unit.This document contains all the designing steps followed to reach the final solution as well as the material selection, manufacturing process and assembly of all the parts that form it.The solution obtained shows to be very competitive with other alternative products, since this new design triples their maximum load capacity while the dimensions are very similar.In this context, the optical appearance was also very important to the company and so it was another main objective of this project. From an aesthetical point of view, the final solution proves to be very compact and versatile since it can either be hidden behind a false ceiling or covered by a plastic case that gives the design a very nice look.Finally, the solution achieved fulfils all the requirements and specification previously imposed. It is reliable, compact, cheap to manufacture, easy to assembly and it has a good optical appearance. .
Den svarta lådans pedagogik : En studie om läsinlärning på behavioristisk grund
AbstractThe phonics is traditionally firmly established within reading acquisition in Swedish schools. The curriculum, Lpo 94 gives spacious independence regarding the question of method and we have to be aware of our own point of view when we are making the decision regarding the method of reading acquisition. Is it tradition or is it our linguistic point of view that is the determining factor? Through this study of literature, different publications from different times are being studied and the ideas and the linguistic point of view are being discussed. Through comparing between the curriculums that have been replaced of one another, and attending to linguistic discussion and research, we will be able to see a change in the linguistic point of view.
Samtal om sexualitet : En studie om socialsekreterares upplevelser och reflektioner kring att samtala om sexualitet med ungdomar som är föremål för utredning
This essay reflects on the thoughts and experiences of social workers in child protection agencies when it comes to talking about sexuality with teenagers, age 13-20, who is being subjected to inquiry. The research is qualitative and based on five semi-structured interviews. It has a phenomenological position and has been analyzed hermeneutically through cognitive and gender theory. Previous research shows that youths who get in contact with child protection often have issues about their sexuality. This study show that social workers in the agencies lack knowledge about this issue and that they seldom talks about it with the teenagers or their own colleagues.

Utveckling av grafiskt pekskärmsgränssnitt
Syftet med detta examensarbete är i första hand att utröna vad som händer med interaktionsspråket mellan operatör och och maskin då ett gränssnitts aktiva yta förminskas. På ett övergripande plan kan syftet utryckas i termer av vad som händer med användarens varseblivning och förståelse av gränssnittet då detta krymper.Det konkreta syftet med detta arbete är att utröna om det går att ersätta ett nuvarande foliegränssnitt (42 x 42 cm) med en pekskärm (10 x 7,5 cm) som har en aktiv gränssnittsyta som svarar mot c:a 10 % av foligränssnittets.Utvecklingen av pekskärmsgränssnittet har gjorts i samarbete med Tetra Pak i Lund. Pekskärmsgränssnittet, som skall ersätta foliegränssnittet, hör till en förpackningsmaskin som emballerar dryckesförpackningar i kartonger. Guidelines av Ben Shneiderman (1992) har legat till grund för gränssnittsutformningen.Utvärdering av det nya pekskärms- och det gamla foliegränssnittet har genomförts med ICS-metoden (Interacting Cognitive Subsystems) och fokus har varit på vad som händer då gränssnittet krymps. En jämförelse mellan gammalt och nytt gränssnitt ligger till grund för att peka på kognitiva förändringar som det nya gränssnittet kan tänkas medföra.Det teoretiska syftet med detta arbete är att utvärdera ICS-metoden i sig, samt att jämföra denna med Shneidermans guidelines..
Du Gjorde Vad!? : Naturligt Beslutsfattande och Intuition hos Experter
Att det idag finns flera metoder och modeller för att fatta beslut är inte konstigt då beslutsfattande sker varje dag och i vissa sammanhang kan ge ödesdigra konsekvenser om det blir fel. Denna kandidatuppsats kan ses som en förstudie för hur naturligt beslutsfattande skulle kunna stödjas genom en förbättrad utbildning till beslutsfattare. Uppsatsen ämnar behandla naturligt beslutsfattande och intuition hos experter inom räddningstjänsten, närmare bestämt om de använder intuition och i så fall vad som ligger till grund för denna intuition. Intervjuer utfördes på räddningstjänsten i Motala efter critical decision method som är framtagen för cognitive task analysis. Inom räddningstjänsten använder sig befälen av intuition när de tar det flesta av sina beslut i fält.
Vågar du bli gammal? : en fallstudie av ett äldreboendes arbete med kvalitetssäkring i form av brukarinflytande
Lindrig kognitiv störning (eng. Mild Cognitive Impairment, MCI) betecknar ett tillstånd av försämrad kognitiv funktion, som inte uppfyller kriterierna för demens. MCI tycks innebära en ökad risk att utveckla Alzheimer och andra demenssjukdomar. Syftet med studien var att förutsättningslöst undersöka antal och typer av subgrupper till MCI som bäst överensstämmer med kognitiva testresultat samt att undersöka utvecklingsförlopp för subgrupperna. En klusteranalys utfördes med testresultat från 287 MCI patienter som utretts på Huddinge sjukhus.

Konsumentbeteenden och h?llbarhet. En kvalitativ studie av hur konsumentbeteenden p?verkar h?llbarhetsaspekterna av online f?rs?ljning av kosmetiska produkter, inklusive returer
The ever-growing e-commerce brings many opportunities for society's consumers and businesses. Digitization has strongly contributed to these opportunities and has, among other things, facilitated the search for information and increased the range for the customer. While the opportunities are many, the increased consumption has also brought consequences. The increase in consumption contributes, among other things, to quantities of deliveries and returns as well as increased waste, all of which results in environmental destruction. The issue of sustainability is very topical today and is influenced by almost everything today.
In connection with the markets changing, the consumers' behaviors and expectations also change.

Storytelling is a complex action that requires many linguistic and other cognitive abilities, like memory and attention. Resent research has shown a correlation between oral story retelling and picture arrangement among children with neurodevelopmental disorders. The present study analyzes if this correlation exists among a convenience sample of children from the general population. 77 children between 3:11 and 9:0 years old accomplished Bus Story Test and a picture arrangement task from WISC III. Significant correlations was found between picture arrangement and Bus Story Test?s subscores sentence length, subordinate clauses and information.

Musikens inverkan på personer med demenssjukdom : -en litteraturstudie
Då befolkningen blir allt äldre ökar andelen personer som drabbas av demenssjukdom. Att drabbas av demens innebär att kognitiva funktioner försämras. Kommunikationsproblem och problem med daglig livsföring, personlighetsförändringar, brister i empatisk förmåga och svårigheter att kontrollera känslor kännetecknar sjukdomsbilden. Det är av betydelse att finna icke-farmakologiska behandlingar då medicinering inte ger önskat resultat. Syftet med denna litteraturstudie var att få ökad kunskap om hur musik påverkar personer med demenssjukdom.
