Lyftkraftsberäkning för vingprofiler: Virvelpanelmetoden

The problem presented in this report is that of finding a method to calculate the lift force from a single-element airfoil of arbitrary shape. A number of restrictions are used in order to simplify calculations while retaining reasonable accuracy. The problem is solved for the two-dimensional case only and no finite-wing effects are taken into account. Furthermore, inviscid and incompressible flow is assumed. The method used to solve the problem is the vortex panel method, with vortex singularities distributed over simplified airfoil geometry.

Reformen, visionen och modellerna - En fallstudie om den offentliga reformens påverkan på stora investeringar i Stockholms stad

The goal is to buildthe car that consumes the least fuel during a race. KTH participated for the first time in 2006.The engine for this competition, DoubleTwo, has been developed within the school. Theprinciple is a two stroke counter piston HCCI engine with variable compression ratio. HCCIstands for homogenous charge compression ignition.

Jämförelse av fyra rundbalspressars packningsförmåga som funktion av grödans torrsubstanshalt :

To succeed, and make money at your animal production you need to feed your animals with high quality fodder. Other condition to succeed is that you keep your production costs at a minimum. To be able to produce baled silage at a low cost it?s very important that the bales have a high density. Density is measured in kg dry matter (DM) per cubic meter. The purpose with this report was to learn more about making silage in round bales and to how much the bale density varies between different brands of round balers.

A cost benefit analysis of public procurement of pork meat : imported, Swedish or locally produced?

Public procurement stands for a substantial part of the total food consumption in Sweden. The majority of the procured food is today imported and according to market trends it?s intended to stay that way. Imported food is favoured for locally produced due to price pressure.

Säljarens förmåga att visa förståelse och empati i interaktionen med kund : En kvalitativ studie om den affektiva och kognitiva empatin 

Syfte: Syftet med vår undersökning är att skapa bättre förståelse för hur en säljare förmedlar empati för kunden i en säljrelation. Tidigare forsknings uppmärksamhet för förståelsen och empatins påverkan utgör grunden till att vi mer specifikt vill undersöka; hur kunden uppfattar att fastighetsmäklaren förmedlar affektiv respektive kognitiv empati i en säljrelation.Metod: En studie av kvalitativ art valdes med bakgrund till studiens syfte. För insamling av kvalitativ data använde vi oss av tidigare forskning samt semistrukturerade intervjuer, vilka utfördes med respondenter som anlitat en fastighetsmäklare inom de närmaste tre föregående åren. Well-grounded theory användes sedan som analysmetod av det empiriska materialet.Slutsats: Studien indikerar att kunden uppfattar både affektiv och kognitiv empati i mötet med fastighetsmäklaren. Vi har genom analysen uppmärksammat skillnader och likheter i respondenternas svar, mer specifikt har vi funnit att kundernas uppfattning av empati upplevs olika av olika personlighetstyper och situationer.Förslag till vidare forskning: Vi anser att vidare forskning bör ta hänsyn till fler variabler, exempelvis ålder, kön, personlighetstyp eller situation.

On-line uppdragsplanering baserad på prediktionsreglering

Modern air battles are very dynamic and fast, and put extreme pressure on pilots. In some unpredictable situations, like new discovered threats or mission plan deviation because of enemy aircraft, the pilots might need to replan their predefined flight route. This is very difficult, if not impossible, to do since numerous factors affect it. A system that can help the pilots to do such a thing is needed. Previous work in this field has involved methods from artificial intelligence like A*-search.
