Jämförelse av olika metoder att generera Bernoullifördelade slumptal givet deras summa
In this master?s thesis the problem of simulating conditional Bernoulli distributed stochastic variables, given the sum, is considered. Three simulation methods are considered, namely the acceptance/rejection technique, Bondesson?s method and the Markov chain Monte Carlo method.To compare the three methods the bias and the standard deviations of the simulated variables are evaluated. The results of the simulation study shows that the Markov chain Monte Carlo method is not the best method for this type of simulation.
Patientupplevd vårdkvalité utifrån olika bakgrunder
I uppsatsen har jag undersökt om och hur mycket olika bakgrundsfaktorer hos patienter påverkar hur nöjda de är med vårdkvalitén. Uppsatsen begränsar sig till läkarbesök inom den offentliga Primärvården (Närhälsan) i VGR. Vi har använt oss av två olika metoder för att analysera data från Nationell Patientenkät från hösten 2011. Dessa är Binär logistisk regression och LASSO logistisk regression. Vi har valt logistisk regression därför att den beroende variabeln inte har intervallskala.

Bärighetskontroll av obundna granular material. En jämförelse mellan olika bärighetskontroller samt en alternativ utvärderingsmetod av bärighet med Lätt Fallvikt
On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.

Feedback och hälsa : en studie hos ett statligt verk
Today, many discussions are taking place through different platforms concerning the huge problem of ill health within modern society. Ill health tends to affect both children and adults. For the adult sector ill health may lead to doctor?s notification of illness in the short term and on the long term permanent disability benefit. In the mass media there are often articles published that point out the rising number of people with sick pay and people being given permanent disability benefit.
Hur påverkas kvinnors hälsa av psykosociala faktorer? : En kartläggning av hälsan bland tillsvidareanställda kvinnor i Sotenäs kommun
Background: Because of the high unhealthy rates among women in the com-mune a project to reduce it have begun. For this reason we have been given the mission from the commune of Sotenäs to study the character of these women's health. Objective: To study the health among permanent employed women in the commune of Sotenäs. Method: Quantitative method. The data have been collected through question-naire survey.
Modellering och styrning av flis till en sulfatkokare
At the Skoghall pappermill, sulphatepaper pulp is produced in a continuous digester originally from 1969. To be able to maintain a high level of production there is a need for a process with few disturbances. Variations in how well the wooden chips are packed in the digester is one form of disturbance. Today there are no available measurements on how well the chips are packed. Instead this is regarded as being constant.
Lågsvavlig fartygsdrift : Permanent drift med MGO på två-takts fartygsdieslar.
Undersokningen omfattar problem som kan uppsta vid permanentdrift pa MGO itvatakts-fartygsdieslar som tidigare har opererats pa HFO. Undersokningen ar utfordmed hjalp av intervjuer samt en litteraturstudie.Den overgripande slutsatsen ar att det ar fullt mojligt med drift pa MGO, det kraverdock en del anpassningar av systemen. Det enskilt storsta problemet ar den lagaviskositeten. Kan inte viskositeten hallas tillrackligt hog sa kommer problem med okatslitage pa bland annat branslepumpar att uppsta.

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.
Sorterar skotaren bort det timmer som skördaren har tillrett? :
The efficiency of the harvesters work is more often reviewed, than the work of the forwarders. In a local Stora Enso office the differences between the harvesters reported volume of timber, and the actual volume delivered to the industry had been noticed. Therefore, the decision was made to do a review on the forwarders work.
The review was conducted together with a worker from Vmf Qbera, who is working daily with wood measurement, in order to get a valid evaluation of the logs. Eight sites were included in the survey, and on each site 50 logs were marked. Approximately one third of the marked logs were pulpwood, and the remaining logs marked were timber.

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.
Biomekanisk mätmetod och ergonomisk analys av träningsmaskiner
To get the maximal output of your exercise in gym machines, there are different factorsto be considered. For example the strength of the muscle varies dependent on the positionof the muscles. To get the best results of the exercise the load has to reduce and increaseat specific positions.This study was made in cooperation with Caretaker Scandinavia AB, a company forsales, marketing and development in health care. They are general agent for Nordic Gymwho works with manufacturing of equipment and machines for gym and fitness.The aim of this study was to generate a method of measurement to evaluate and controlthe biomechanics of Nordic Gym´s workout equipment. A protocol for an ergonomicanalysis on the equipment has also been elaborated.One of the methods to measure the biomechanics was to measure the torque through thewhole movement.
Akustisk mätning av U-värde
This pre-study investigates the possibility of U-value measurements through an acoustic method. A hypothesis about an acoustic model built on acoustic theories combined with U-value theories is presented to answer the questions:
? Can U-value theory be combined with acoustic theories?
? Can the coefficient of heat be affirmed trough an acoustic measurement?
The idea for this dissertation begun with a logical idea in mathematical similarity, between the coefficient of heat transmission units and sound intensity units.
The U-value theory is based on assumptions such as initial resistance for inner walls and initial resistance for outer walls. The resistance in the material is interpreted through sound intensity theory.
The argument is built upon mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB.
