Prediktion av elproduktion : Modellering av icke reglerbara vattenkraftverk

The main objective of this study is to divide a number of colorectal cancer cases into subgroups based on their molecular features using cluster analysis. The data used is supplied by a research group at Pathology, the Department of Medical Biosciences, Umeå University, and consists, after some preparation, of 455 observations which is a larger data set than many similar studies. The molecular variables that the clustering is based on are CIMP (CpG Island Methylator Phenotype), MSI (Micro Satellite Instability), BRAF- and KRAS-mutations. These are categorical variables and consequently the clustering method used is PAM (Partitioning Around Medoids) which is particularly useful with data on diverse variable level. The final analysis results in four subgroups that are represented by different combinations of attributes on the aforementioned variables.

Höghastighetståg - Är det framtiden?

AbstractConsider a ?uid being heated from below. The heating leads to an upward convectiveforce that is counteracted by the viscous forces of the ?uid. If the convectiveforce is large enough in comparison to the viscous forces the ?uid will be put in anunstable state.

Egengruppseffekter på åldersbedömning och attraktivitetsbedömning av röster

I studier av igenkänning av ansikten har egengruppseffekter (own-group bias) kunnat framkallas utifrån indelning av deltagarna i påhittade personlighetskategorier. Denna studies syfte var att undersöka om egengruppseffekter på liknande sätt kunde framkallas på ålders- samt attraktivitetsbedömning av röster. Totalt 38 deltagare fick utföra ett falskt personlighetstest i syfte att dela in dem i två grupper: röd och grön. Därefter presenterades 36 röstprover ett i taget med en röd eller grön bakgrundsfärg på datorskärmen, medan deltagarna skattade talarens ålder samt röstens attraktivitet. Resultatet visade ingen effekt av indelning i personlighetskategorier.

Lönsamma erbjudanden : Hur tjänsteerbjudanden och dess kunder formas av Optional Framing

ABSTRACT Title:                         Lucrative dealsHow service offers and its clients is forms by Optional Framing                 Level:                       Bachelor, Business AdministrationAuthor:                     Gabriel Krogius, Mikaela SörensenSupervisor:              Jonas Kågström, department of economicsDate:                         2013, AugustIntroduction:           That the human mind may be directed by how an offer is designed is not news. However, what is new in the following thesis is whether a person is affected in the case of a service rather than, as previously research, a physical product. Does a person find it harder to separate with something rather than to add an option?Aim:                          The aim for this thesis is to examine how Optional Framing has affection on service offerings/companies, and in this case on real estate brokerage services. Is it, as earlier, when the human can form her own offer, the final price ends up higher when she is about to add options than removing them?Method:                    The thesis emanates to achieve earlier results where the difference in this case is that our thesis is targeting service offerings.

Prisskillnader mellan privata och publika bolag : En studie om illikviditetsrabatten och dess varierande storlek

The main objective of this study is to divide a number of colorectal cancer cases into subgroups based on their molecular features using cluster analysis.

Typ av demens relaterad till övriga sjukdomar och tidigare genomgången anestesi/kirurgi : En retrospektiv pilotstudie

This retrospective study reviews and investigates type of dementia, related to co morbidity, symptoms of dementia, previus anaesthesia/surgery, intraoperative events and postoperative cognitive symptoms. The patient co morbidity was compared to occurrence in an age-matched population of 1095 individuals. Fifty-two patients with different types of dementia participated. Data was collected from patient journals.Compared to population, heredity for dementia, heart insufficiency, hypertension, depression and B12- deficiency was more frequent in the patients. B12- deficiency was common in vascular dementias and "burn-out syndrome" in early-onset AD.

Internationell ekonomi och svenska institutioner - välfärd, solidarisk lönepolitik och internationalisering

The topic of interest is why Swedish unemployment after OPEC - 1 remained exceptionally low, compared to the OECD average. The object of study is the evolution of welfare institutions, like the Rehn ? Meidner model, after WWII, and the aim is to explore why the institution of solidaristic wage bargaining collapsed coming the nineties. Deployed theoretical perspectives are how domestic institutions determine a country's adaptation to alterations of the international economic system. However, equally important are how policy objectives, like full employment, becomes institutionalized and therefore guides the actions undertaken.

Att uppfinna ett nytt hjul eller att fastna i gamla hjulspår : En studie i priming av användbarhet och originalitet vid idéskapande

Syftet med studien var att undersöka priming med exempels påverkan på skapelsers kreativitet. Effekterna av priming skulle testas i formen av egenskapspriming såväl som konceptuell priming och mätas utifrån både en användbarhetsaspekt och en originalitetsaspekt. Ett delsyfte var också att undersöka sambandet mellan intresset för att ta fram en skapelse och en skapelses grad av originalitet samt användbarhet.Primingeffekterna prövades genom ett experiment där 36 studenter delades in i 3 grupper som fick i uppgift att ta fram IT-lösningar för kollektivtrafiken. 2 av grupperna primades med var sitt exempel på hög originalitet respektive hög användbarhet.Effekterna av egenskapspriming undersöktes sedan genom en jämförelse mellan grupperna över hur stor andel av de framtagna lösningarna som innehöll egenskaper från exemplen. För att undersöka effekterna av konceptuell primingen gjordes en jämförelse av originaliteten och användbarhet hos dessa gruppers lösningar jämfört med de framtagna av en kontrollgrupp utan tillgång till exempel.

Remitteringar och minskad fattigdom : Finns det ett statistiskt signifikant samband?

Samtidigt som fattigdomen runt om i världen stadigt minskar så växer sig remitteringsflödena allt större. I denna uppsats undersöks om remitteringar kan anses vara en bidragande faktor till detta. För att kunna undersöka vår frågeställning har vi genomfört en regressionsanalys på ett dataset vi sammanställt bestående av olika mått på fattigdom och andra variabler som rimligen kan antas ha en effekt på fattigdom från 83 utvecklingsländer. Resultaten från vår studie tyder på att viss diskrepans råder inom forskningsområdet då vi inte har lyckats finna något statistiskt signifikant samband mellan remitteringar och minskad fattigdom. Det är tvärtemot vad tidigare forskning har kommit fram till.

Tidiga membranförändringar i hingstsperma som används för artificiell insemination :

The Annexin-V/propidium iodide (AV/PI) assay detects early membrane changes in spermatozoa and viability using flow cytometry. It is an objective method that evaluates a much larger number of single spermatozoa compared with the usual estimation of motility, the most commonly used method for routine sperm evaluation. In the present study four ejaculates from four stallions were used in a split-sample design to investigate whether and how the number of intact spermatozoa is affected over time and after incubation at different temperatures, either those recorded during shipment of stallion semen for AI (9 or 5°C) or room temperature (20°C). The Annexin-V results did not reflect the motility results that were monitored in parallel. While motility decreased over time, the number of spermatozoa with intact membranes (viable) remained unchanged for at least 21 hours following a short period of initial instability.

Gotland och Montenegro - att söka Bysans i den västerländska kulturen : en undersökning av Manastir Mora?asoch Mästerby kyrkas muralmålningar

In this essay the author has chosen to analyze the similarities and differences between some of the northern Europe?s late Mesolithic and Neolithic cultures. The research is of a processual standpoint and the information is mainly gathered from secondary sources as well as ethnological studies. The material collected has been analyzed in both a processual and a post-processual manner to most accurately study the foundations of the three primary theories describing the Pitted Ware Culture?s origin.
