Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

The purpose of this paper has been to identify which modern search functions user of Smartphones are using, why just these functions are being used, and how they have affected the way users acquire information. Modern search functions in this paper means searches that are not based on text, i.e. ways to search for information by other means than writing something into a search field. To identify this, two studies were conducted, one with a questionnaire being distributed with the help of Google Docs through social networks, and one with four interviews with users of modern search functions for Smartphones. The study showed that even though 76 % of Smartphone users are aware of at least one modern search function, only 29% uses one on a regular basis.

This thesis aims at examining to what extent a few, algorithmically very easily extractable document features can be used to classify electronic documents according to genre. A set of experiments is therefore carried out, using only 11 such simple features in an attempt to classify 84 documents belonging to electronic academic journals into three manually identified genres: table of contents, article, and review. The 11 features are also divided into three sets, containing metrics of words and sentences; punctuation marks; and URL links, respectively. The performance when using these sets of features is then measured with regard to classification accuracy, using a k-NN classifier, four different values of k (1, 3, 5, 7), and both leave-one-out and 10-fold cross-validation. Best results are achieved when using all three feature sets (i.e.

The purpose of this study was to investigate parents' knowledge about diet and dental caries. The survey was conducted using a structured questionnaire consisting of 19 questions regarding knowledge of diet and caries, and preventive measures. The questionnaires were distributed to parents who were visiting a dental hygienist or prophylaxis nurse with their children aged 0-3 years. A total of 88 completed surveys were collected. The study showed that the majority of the parents had knowledge about diet and dental caries.

?I have a dream that one day on the red hills of Georgia, the sons of former slaves and the sons of former slave owners will be able to sit down together at the table of brotherhood.? Martin Luther Kings jrs. starka stämma ekade ut ur högtalarsystemet och de 250 000 medborgarrättsaktivisterna som var samlade vid George Washington monumentet i USA:s huvudstad  instämde i ett jublande bifall. Året var 1963 och Martin Luther King jr., hade i nio år varit känd som den amerikanska medborgarrättsrörelsens främste talesman, när han i sitt tal till det amerikanska folket yttrade sin vision för det amerikanska samhällets framtid.     Denna uppsats beskriver det afro-amerikanskafolkets historia, från slaveriets bojor i de Nordamerikanska kolonierna i slutet av 1600-talet, till kampen för fullständiga medborgerliga rättigheter i 1950- och 60-talets USA.

In this work we have compiled results from various studies concerning medical conditions that may possibly be avoided by castration and the effects that may occur after castration of the healthy bitch. The work is a literature review but it also includes a summary on the age recommendations for castration of the healthy bitch, castration before or after the first heat and the castration method most commonly used of ovariohysterectomy and ovariectomy. The summary is based on a questionnaire answered by personnel from 20 veterinary clinics and animal hospitals evenly distributed throughout Sweden.The summary showed that ovariohysterectomy was the most common method of castration and the recommendation in age ranged from 6-12 months. Regarding castration before or after the first heat 75% of the veterinary clinics and animal hospitals answered that they recommended castration after the first heat. Literature study shows that there are both advantages and disadvantages of castration of the healthy bitch and that it therefore is important that each bitch get a personal and individual evaluation before a decision is taken concerning a castration..

In this Bachelor thesis I explore sound and room as elements in design of user interfaces, both theoretical and practical in a specific application domain, to identify some of the advantages and disadvantage associated with these elements. As application domain I studied email clients and their usage at home amongst students at Blekinge Institute of Technology. In the study I found an activity, which seems to be highly distributed in the physical room where the user is located. The activity was notification of email and could take place in an arbitrary location of the home. I then augmented this activity with ideas from my theoretical assumption about room and sound. The result was a rule-based agent for notification of email, which primarily uses sound as interaction style..

To business owners and consumers electronic commerce means new conditions and possibilities. Often and specially at the Internet information between consumers and sellers is asymmetrically distributed. Among the consumers there is a shortage of confidence in electronic commerce. In order of a positive development of electronic commerce it´s important to find a solution to the shortage of confidence. Confidence may be created by legislation or by self- regulation.

In the faster growing pace of changes and competition in the global economy, factors promoting group effectiveness are of interest. How do components of leadershipstyle, especially transformational, team climate and selfefficacy correlate? To answer this question 3 questionnaires regarding leadershipstyle (MLQ), team climate (TCI-Short) and selfefficacy (self developed) were distributed to employees of a Swedish installation company (108 participants). Moderate positive correlations were found between climate and selfefficacy and between varying elements of leadership and selfefficacy. The leadership behaviour Contingent Reward correlated moderately with all climate dimensions and strongly with selfefficay.

Titel: En kvalitativ fallstudie hur aktörer skapar och bibehåller förtroende i organisationer med fördelat ansvar Nivå: Kandidatuppsats Författare: Jens Bergvik och Hanna Eriksson Handledare: Stig Sörling och Tomas Källquist Datum: 2015 ? januari Syfte: Enligt tidigare forskning är förtroende grunden för många av organisationens resultat och basen i fungerade relationer och samarbeten. Sambandet mellan förtroende och den ansvarsfördelade organisationen är identifierad men saknar praktisk forskning, då en ansvarsfördelad organisation kräver samarbete beroende på att många har befogenhet till ansvar och beslutsmakt. Syftet med denna studie är därmed att ge en ökad förståelse för hur aktörer skapar och bibehåller förtroende samt att belysa förtroendets roll i ansvarsfördelade organisationer. Metod: Studien har utgått från ett hermeneutiskt perspektiv och fenomenet som studerats ses vara av socialkonstruktivistisk art. Med hjälp av deduktion har teori och empiri arbetats fram där grunden för studien har varit i form av en fallstudie som antar ett kvalitativt angreppssätt genom semistrukturerade intervjuer. Resultat & slutsats: Studien tyder på att förtroende är svårt att beskriva då det uppfattas som en abstrakt fenomen och därav avsaknaden av konkreta verktyg.

Wind damages next to strip roads in 1st and 2nd thinning in Boxholm, Östergötland Anneli Fransson, SLU, inst f sydsvensk skogsvetenskap, Examensarbete no 108 Wind damage is something we are all familiar with since the storms Gudrun (2005) and Per (2007). Research about strip roads and wind damage is very limited. It is commonly known that the trees next to the strip roads more often fall whit heavy winds, and the purpose of this thesis was to verify this statement. Data was collected from first- and second thinnings at Boxholms Skogar AB, Östergötland. In first thinnings data was collected from both spruce and pine stands and second thinnings only data from spruce stands was collected.

Marknaden för de allt populärare smarta telefonerna är splittrad. Detta innebär nya utmaningar för utvecklare. Vill man vara säker på att nå mer än hälften av sin målgrupp med en mobilapplikation så måste man utveckla för minst två plattformar, något som kostar både tid och pengar. Ett antal så kallade multiplattformsverktyg har tagits fram för att lösa detta problem. Dessa låter utvecklare använda en och samma kodbas för flera olika plattformar.

We studied how librarians would adapt to telework, the performance of job responsibilitiesfrom home. We found'that all duties could be accomplished. but to varied extents.Computerbased searches, interlibrary loans, acquisitions, indexing and telephone referenceservices are the duties most likely to adapt to telework whereas cataloguing andclassification probably are best performed in the ordinary workplace.Most duties would demand access to technical means of assistance when performed fromhome. Connections to the library's local network, directly or via modem, are requiredbecause it is unrealistic to expect librarians to telework with fewer tools than theyordinarily have available. Although librarians generally believe that teleworking will nothave a large irnpact on the operation of the library, most would like to telework.Whether teleworking is a viable strategy depends on the characteristics of the duties, thelibrarian's desire to telework, but also on the size of the library, the size of its staff, thelibrary's activities, and how work is distributed between librarians..

In the proposition Nya förmånsrättsregler, 2002/03:49, the government suggests a new bill of beneficial rights, or FRL. The proposition has several changes, mostly for The Banking system. One of the changes is that the banks´ individual beneficial rights shall be replaced by a general beneficial right, where the beneficial value never exceeds 55 percent of the value of insurance bonds. Previously, the beneficial value was 100 percent.The purpose of this essay is to evaluate the relationship between the banks´ activities, and the new bill of beneficial rights, especially what the effects will become for the public companies within the printing houses, with 1 - 49 employees in the Skåne Region.The survey includes a total of 142 companies and it was distributed via e-mail. The conclusions from the study are that there are tendencies of increased difficulties for companies to get their credits granted by the banks.
