On a request from the water sewage plant Gryaab in Gothenburg a power quality survey wasperformed. The voltages and currents have continuously been sampled in the incoming 10 kVsubstation HSP01 from April-August 2008. Power quality measurements were also performedin Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of theinduction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps tothe plant. The reason for the latter measurement was due to registered negative transients eachtime the motor was connected to the grid. The cause of the transients could be explained by thecoupling in the substation, the ageing of the motor which could result in damage of thebearings or resonance in the motor circuit which amplifies high frequency harmonics.

The eld of Brain-computer interfaces (BCI) concerns linking together an external device with the brain of a human or an animal. By doing this the conventional use of a mouse or keyboard can be circumvented, which can greatly benefit people with different types of diseases that cause paralysis or other loss of motor control, such as Amyotrophic lateral sclerosis (ALS). A BCI can also be used for cognitive training of either healthy or mentally impaired subjects to increase cognitive capabilities.In this thesis an implementation of an interface is made against such a device, the Emotiv EPOC Headset. The result is meant to be a stable basis for further study using the device. An in-depth study of the history of EEG and its current use in clinical work and research in the topics of BCI as well as Human-computer interaction (HCI) is presented.

Utg?ngspunkten f?r den h?r uppsatsen ?r det s? kallade implementeringsproblemet, som inneb?r ett glapp mellan beslut och genomf?rande och har betydelse f?r fr?gor om makt, ansvarsutkr?vande, resultat och effektivitet. Uppsatsen j?mf?r implementering av tv? olika arbetsmetoder i en hierarkisk organisation, Polismyndigheten. Ett m?l med ombildningen till en Polismyndighet 2015 var f?rb?ttrade resultat och ?kad kvalitet i verksamheten. Statskontorets utv?rdering av reformen 2018 visade dock p? sv?righeter i styrningen, exempelvis vad g?ller att f? genomslag f?r olika arbetsmetoder.

Nasdaq OMX Stockholms stadigvarande positiva utveckling kan resultera i ett dyrare, mindre attraktivt, aktiepris och fo?rorsaka beslut om att genomfo?ra en aktiesplit. I den ha?r uppsatsen underso?ks, genom en eventstudie, om annonsering och genomfo?rande av aktiesplit ger upphov till o?veravkastning fo?r bolag noterade pa? Nasdaq OMX Stockholm mellan a?ren 2004- 2014. I fo?ljande eventstudie har bolag kategoriserats efter bo?rsva?rde fo?r att a?ska?dliggo?ra om det fo?religger skillnader i o?veravkastning beroende pa? bolagsstorlek.

Studiens syfte var att undersöka om det fanns skillnader i personlighet och val av konfliktstil beroende av vilken placering respondenterna hade i syskonskaran samt om Locus of control skiljde sig mellan olika Äldersgrupper. Samband mellan chefers konfliktstil och personlighet undersöktes ocksÄ. De 103 respondenterna som var mellan 25-75 Är, 63% mÀn och 37% kvinnor, besvarade en enkÀt som bestod av demografiska frÄgoroch arbetsrelaterade frÄgor om chefskap. Tre test anvÀndes; ett personlighetstest, RottersLocus of Control och Thomas-Kihlman?s konfliktstiltest.

Syftet med studien a?r att belysa hur elever med specifika la?s- och skrivsva?righeter/dyslexi upplever sina mo?jligheter att utveckla en sja?lvka?nnedom kring sitt eget la?rande. Studien har genomfo?rts som en kvalitativ studie da?r totalt sex ungdomar fra?n tre olika skolor har intervjuats. Tre av dem a?r elever pa? ho?gstadiet och tre pa? gymnasiet.

AbstractThe purpose with this study was to get knowledge if there are any possible differences in, and correlation between, experienced stress, experienced demands, experienced control and experienced social support in correlation to shiftwork.The study was made at two central hospitals in south of Sweden and had 90 participants (78 women and 12 men) that answered a questionnaire in the current variables. The result in experienced stress showed that there were no differences between shift workers. The results showed a difference between the day- and the nightshift in the correlation between control and stress. The writers speculates that the reason why the nightshift experience high stressvalues with high control can depend on the lack of presence by higher managers, compared with the dayshift. .

Andelen unga med intellektuell funktionsneds?ttning som kommer i arbete efter avslutad gymnasieutbildning ?r oproportionerlig l?g. Forskningsl?get visar p? en bild av en marginaliserad grupp i samh?llet som i ?verg?ngen mellan skola och arbetsliv st?lls inf?r en komplex verklighet med flera inblandade akt?rer. Elevernas m?jlighet att under gymnasietiden prova olika typer av arbete n?mns som en av flera framg?ngsfaktorer f?r anst?llning men elevernas r?ster om betydelsen av arbetsplatsf?rlagt l?rande, apl, saknas i stort sett helt inom forskningen. Syftet med studien var att unders?ka hur n?gra elever som avslutat sina studier p? anpassad gymnasieutbildning upplevde och erfor l?rande p? apl och syftet var ocks? att unders?ka deras uppfattning om betydelsen av apl f?r att komma in p? arbetsmarknaden, vilket preciserades i f?ljande fr?gest?llningar: Vilka erfarenheter av och uppfattningar om l?rande p? sin apl-plats har tidigare elever p? anpassat gymnasium? Vilken betydelse anser eleverna att apl har f?r m?jligheten till anst?llning? Studien tog sin teoretiska utg?ngspunkt i sociokulturellt och specialpedagogiskt perspektiv och metoden som anv?ndes var semistrukturerade kvalitativa intervjuer som sedan analyserades tematiskt. Resultatet visade att apl givit studiens deltagare viktiga erfarenheter och yrkesrelaterade f?rdigheter som f?r de flesta lett till syssels?ttning och arbete.

Syftet med studien var att ta reda pa? hur man kan fra?mja lek fo?r barn med autistiska symptom som bor pa? korttidsboenden. En kvalitativ intervjuunderso?kning gjordes med sex deltagare och analyserades sedan genom en tolkande fenomenologisk analys (IPA). Fyra huvudteman med tillho?rande tva? underteman var valdes ut.

Cyberterrorism kan ses som ett relativt nytt, komplicerat och diffust hot som uppenbarat sig till följd av en snabb IT-utveckling. För Försvarsmakten kan detta hot innebÀra en ny utmaning eftersom doktrinen som skall fungera som vÀgledning i verksamheten börjar bli inaktuell. De grundlÀggande förmÄgorna, som Àr en viktig del av doktrinen, ses som tankemÀssiga hjÀlpmedel för att Försvarsmakten skall kunna analysera, samordna och beskriva verksamheten. Syftet med denna uppsats Àr att utreda hur pass anvÀndbara de grundlÀggande förmÄgorna Àr som tankemÀssiga hjÀlpmedel nÀr Försvarsmakten stÀlls mot ett hot som cyberterrorism. Detta görs genom en analys utifrÄn ett scenario dÀr Försvarsmaktens ledningssystem utsÀtts för en cyberattack med ett efterföljande resonemang om tillÀmpningen av förmÄgorna.

In this bachelor thesis, diagnostic methods for one of Siemens stem inlet control valves have been developed. The work has taken place during ten weeks at Siemens Industrial Turbomachinery AB in FinspÄng. The company produce steam- and gas turbines and also provides service and maintenance. The purpose with this project has been to develop diagnostic methods that oversee the health of the control valves. By using the developed methods you will know when it?s time for maintenance.

Background: Performance measurement as a management control tool has received considerable academic attention. As the number of inter-organisational relationships, such as customer-supplier relationships, increases, there is a new scope for performance measurement as a management control tool. In order for a company to assess the effectiveness of its supplier relationships it has to define, measure and evaluate variables that are critical for the success of the relationship. The role of management control, and thereby of performance measurement, has increasingly been discussed in theory. However, empirical research in this area is still somewhat limited.
