The purpose of this thesis project was to analyse and evaluate different systems for installation of piperun in ceilings. Main focus lay on how the systems influence the installer from an ergonomic point of view as well as productivity in terms of installation time. Several studies have been performed during this project using a variety of methods such as observations, interviews, questionnaires a
The purpose of the thesis was to design a new rotor blade for the KTH test turbine according to present design guidelines for gas turbines manufactured at Siemens Industrial Turbomachinery in Finspång. Stage one of a real gas turbine was used as a reference for the aerodynamic design providing a starting point for the project. Using similar gas conditions the new rotor blade was optimized with reg
Biogenic volatile organic compounds (BVOCs) play an important role in the climate system by altering the oxidative capacity of the atmosphere, affecting the lifetime of methane and production of tropospheric ozone, and by contributing to formation of aerosols and clouds. Salix plants (willows) are well-documented emitters of BVOCs and this study aims to examine emissions in a Salix biofuel plantat
A new motion simulator has been developed to simulate Minesto AB’s tidal energy converter flying in water. The motion simulator is as a part of a new computer based development environment, aiming to shorten the company’s development process. The environment consists of a hydrodynamic analysis together with the new simulator to evaluate the performance of the company’s tidal energy converter. The
Syftet med föreliggande studie var att undersöka experimentledareffekter i ett false belief-test. Utifrån detta syfte konstruerades ett false belief-test i form av en kort tecknad film. Med utgångspunkt i tidigare forskning var hypotesen att de barn som tittade på filmen utan experimentledarens närvaro skulle klara false belief-uppgiften bättre än de som tittade tillsammans med en vuxen. Det fanns
This paper aims to examine how hotels within a geographically confined space, such as Lund, are working with innovation to create competitive advantages in terms of improved results. We have performed a qualitative study using semi-structured interviews with representatives from hotels in Lund. In our analysis, we used a pattern-matching analysis technique and made comparisons between the differe
