Tillförlitlighet i Stockholms elnät : En analys med hjälp av Tekla NIS

Outages in the electric grid can be costly for society. Because of this, reliability is one of the parameters used to regulate network companies. Reliability in electrical grids can be measured with SAIDI, system average interruption duration index, which for Fortum Distribution has increased in Stockholm?s distribution network (11 kV) in the early 2000?s.By using outage data for Stockholm from 2011-2013, sets of parameters to be used for reliability calculations in the network information program Tekla NIS were derived. Two different options for investment were then analysed: changing old cables with high fault frequencies, and installing automatic switching in distribution substations.

The Reading the Mind in the Eyes Test - Revised Version á la Andersson & Karlsson

Introduction: The Reading the Mind in the Eyes Test is a widely used test for measuring aspects of social cognition. The aim of the present study was to provide results from a group of typically developing Swedish children (age 9-12) and to compare these results with children and adults in other Swedish and English studies, as well as results from a group of children with Asperger syndrome. Method: A Swedish version of the child version of the test was completed by 83 controls and by six children with Asperger syndrome. Results were compared between the two groups and with data from other studies. Results: The children in the current study did not differ on scores compared to children in the same age group in other studies.

Perceptuell bedömning av dysartri: jämförelse av detaljerad kontra övergripande analys

The aim of the present study was to compare two differenttypes of assessment of dysarthria to be able to conclude which methodmight be more suitable for use in research and in clinical practice.Five speech pathologists with extensive experience assessed 20different recordings of individuals with dysarthric speech using twodifferent forms, one more detailed and one designed for a more overallassessment. In the detailed form 30 aspects of voice and speech wereanalyzed. In the short form 5 overall aspects of voice and speech wereanalyzed. Six of the recordings were duplicated to serve forassessment intra-judge reliability for each form. The results show thatthere was a high correlation between the two forms and that theymeasures the same types of speech deviations although on differentlevels of details.

Mäns kroppsuppfattning: en kartläggning och reliabilitetsstudie

Man has through out times and in all cultures shaped their bodies to the existing bodily ideals. Men's bodily ideals had changed over the last thirty years to a more muscular, less bodyfat and more V-shaped body. Men and women focus their attention to different body parts. That is why there is a need for a questionnaire witch is specially designed for men. The purpose of this study was to deliniate the body image of men aged 20 to 30 years and to test the reliability of the questionnaire "Mäns kroppsuppfattning".

Utveckling och psychometrisk testning av "Pain Impact Inventory" - en jämförelse mellan två olika ansatser

The aim of this study was to develop and psychometrically evaluate an instrument for measuring the impact from chronic pain on daily life. Traditionally psychometric evaluation is done with parametric methods even if the items are ordinal data. In this study the instrument to be developed is solely based on ordinal data, and the psychometrically evaluation is done with both traditional methods (i.e. parametric statistics) as well as with non-parametric methods. These two different ways of psychometrically evaluation are then compared with each other.

Optimering av prioriteringsverktyget Werner

E.ON Elnät has in their project Operational Performance developed a priority tool forconstruction and operation. The tool will help the users to increase the capability to prioritybetween new development projects and removal of faults. The tool can be seen as a measuringfor different bay?s reliability, size and the community usefulness. The result of the priority isdirectly connected to which calibration that is chosen in the tool.The priority tool is still under development and there is therefore an uncertainty about howsensitive the tool is for changes in the calibration.

Maximal kraftutveckling under menstruationscykeln: En litteraturstudie

Bakgrund: Träning medför hormonella förändringar och anpassning av vävnader. Under kvinnans menstruationscykel fluktuerar halten könshormoner. International Organization for Physical Therapy in Women?s Health (IOPTWH) anser att vårdutbildningar på grundnivå bör inkludera kunskap kring kvinnans specifika fysiologi. Detta bör tas hänsyn till och inkluderas i sjukgymnastens arbete, rehabilitering och träning av kvinnliga patienter.

Effektiv styrketräning för vältränade med fokus på att öka maximal styrka och muskelmassa: en litteraturstudie

Bakgrund: Styrketräning kan öka muskelstyrka och muskelmassa för såväl otränade motionärer som vältränade elitidrottare. Teorierna kring effekterna av olika typer av styrketräning baseras i stor del av forskning på otränade individer. Syfte: Syftet med denna studie var att undersöka vilken form av styrketräning som ger en frisk, redan vältränad individ störst ökning i maximal styrka och/eller muskelmassa. Metod: Studien är en litteraturöversikt med granskning och bedömning av studier som avhandlat olika styrketräningsformer på vältränade individer med >2 månaders erfarenhet utav styrketräning och som utvärderat resultatet i maximal styrka eller muskelmassa. Artiklar söktes i databasen PubMed.

Stuttering Severity Instrument 3: Svensk översättning och utprövning

The main purpose of this study was to translate Stuttering Severity Instrument 3 and to evaluate its reliability and validity. Five speech-language pathologists assessed 35 adults who stutter with this assessment tool. Overall the results showed a very high inter- and intrarater reliability. A highly significant correlation between Stuttering Severity Instrument 3 and ratings of severity, made by the speech-language pathologists, strengthen the validityof Stuttering Severity Instrument 3. No correlation was found between the total score of Stuttering Severity Instrument 3 and the self-report measure Overall Assessment of the Speaker's Experience of Stuttering, whichindicates a lack of social validity in Stuttering Severity Instrument 3.

Bilateral deficit vid excentrisk och koncentrisk muskelaktion : En jämförande studie mellan den summerade unilaterala och bilaterala kraftutvecklingen hos roddare visavi sprinters

AimThe main aim of the study was to investigate the difference in bilateral deficit between rowers and sprinters during maximal eccentric/concentric muscle actions.? Are there any significant differences in bilateral deficit between rowers and sprinters?? Do the amount of years in practice effect the bilateral deficit?MethodFourteen male subject participants divided in 2 equal sized groups (7 individuals in each group; rowers and sprinters) performed maximal unilateral/bilateral eccentric and concentric muscle actions in a leg press machine at a velocity of 0.2m/s. The range of motion in the knee joint was 70° ? 140°. Dependent t-tests have been performed within each group pre and post test.

Validering av smärtformulär för katt

The objective of this study was to assess validity and reliability for five different owner-completed instruments evaluated to assess chronic musculoskeletal pain in cats. All of the instruments were questionnaires, three asking about behavioral changes, one about the degree of pain and one about quality of life. One of the instruments was written originally in Swedish, the other four instruments were translated into Swedish before use. Data available were records from 57 cats with no signs of pain and 11 cats with different pain-related diagnoses. The diagnoses were ensured by clinical examination including palpation and manipulation of joints, gait testing on a force-plate and X-ray scans. Instrument 1 was completed by 57 pain-free and 11 pain-affected cats.

Att arbeta med ständig osäkerhet : En studie av High Reliability Organization

There are certain organizations that manage to handle risk in such a successful way that they almost stay error-free, in spite of the fact that they daily face the risks of accidents. These organizations are usually given the name High Reliability Organizations (HRO). While the most common example is that of a nuclear plant the variety of what organizations can fit into the category is extensive.The purpose of this study is to describe safety culture and theories about HRO and how these can be found in practise within an organization.This qualitative research uses influences of ethnography in its method. The ethnographical approach was picked due to the field of the study and the cultural context in which it is set.The results of the study identify a number of elements sorted into four themes. These themes are deemed compatible or non-compatible with relevant existing theories.

Analys av tanniner : från granbarksextrakt

The objective for this master?s thesis was to test and evaluate two methods for determining the content of tannin in a pinebarkextract. The methods used at Södra for this previously have not been specific enough, only the amount of polyphenolics have been measured. One of these methods is a test based on the Stiasny test and it determines the extracts ability to form a gel with formaldehyde. When this test was carried out it showed that the extract did not contain much tannin.
