Kalibrering av en transient GT-Power modell av en SI PFI turbo motor

I detta arbete behandlas transient simulering i ett 1D-simuleringsprogram, i dettafall Gamma technologies GT-Power. Vad som behöver ändras i en modell för attden skall kunna simulera en motor under transienta driftsfall med godnoggrannhet har undersökts. När detta är gjort, skall det undersökas hur väl dentransient kalibrerade modellen kan simulera en motor med förändrad rörgeometripå insugs- eller avgassidan, och vad som måste omkalibreras om detta inte ärfallet.Den viktigaste slutsatsen av detta arbete är vikten av att ha en korrekt framtagenkompressormapp i modellen. Den som fanns tillgänglig under arbetet hade baramätdata ned till 70000 rpm. Detta resulterade i en överskattning av massflödet iden lägre regionen i den av GT-Power framställda kompressormappen.

Slack på mellanchefsnivå : Ger budgetstramhet och budgetdelaktighet önskade effekter på slack?

The function of budgetary controls is to control the resource allocation within companies. It can also be an instrument for measure and control subordinates and/or business units? performance (Van der Stede 2001). This paper concerns the latter; when the budgetary control function is used to measure and control subordinates performance based on budget. Previous research in this area has not yet accomplished to explain the effects of tight budgetary control which Hartman (2000) considers as the main issue to be concerned about in management accounting research.Previous research has presented contradictory findings regarding tight budgetary control explained by positive effects as well as negative effects during the last decades.

Förbättrad muskelfunktion och balans hos äldre kvinnor efter sex veckors funktionell träning

Sweden is the country that has got the largest amount of elderly in the adult population in the world. The physical activity level decreases as we grow old and we experience muscle mass loss and a bone density reduction. This leads to an increased risk for falls and subsequent fractures. The purpose of this study was to investigate whether an exercise program could affect muscle function and balance ability to prevent falls. 17 women (age 64-79) participated in this study and was assigned to a control group (n=7) and an intervention group (n=10).

Fastighetsförvaltning, service och kontroll : En undersökning av kvartersvärdarnas funktion i olika områden

In 2005 a public housing company in Uppsala, Sweden introduced the service quarter host. The focus on comfort (life quality in American programmes) is similar to the non-tolerance programmes. The idea of non-tolerance derived from the theory of Broken windows. The purpose is to examine how the service works according to the theories of Broken windows and social control. The aim is also to examine if the manifest and the latent functions are the same in different areas.

Kostnadsallokering genom ABC-kalkylering ? en empirisk studie av OMX

As IT service departments in organisations are becoming more complex and customised, the indirect costs are increasing in relation to the total costs. The difficulty of fully estimating and identifying the spread of the cost in the IT service department is increasing. As a result, firms tend to budget the business unit as a total cost rather than as a spread of defined costs. In order to deal with this challenge an ABC calculation will be applied. The Time Driven ABC model will be conducted in OMX´s Servicedesk unit within the IT services.

Ursäkta, var är toaletten? Patienters upplevelse av att få en tillfällig loop-ileostomi nedlagd efter rektalcancerbehandling

Introduction: Reversal of a temporary loop-ileostomy is the final step after a long treatment for rectalcancer, an event that the patient has been looking forward to for a long time. Studies have shown that patients often have a significant impact on the bowel function after reversal of the stoma.Aim: To describe how the patient experienced the first time at home after reversal of a temporary loop-ileostomy due to rectalcancer. Method: Qualitative semi-structured interviews, with 15-20 patients who have undergone reversal of a temporary loop-ileostomy due to rectal cancer, will be conducted. The interviewes will be analysed using qualitative content analysis according to Graneheim & Lundman (2004). The patients will be recruited from the colorectal unit at Sahlgrenska University hospital/Östra and from the surgical unit at Kungälvs hospital.
