1. 1. The driving forces of Venture Capital funding in Sweden - A longitudinal study of the determinants and principal components of Venture Capital funding in Sweden from 2001 to 2020

   University essay from Göteborgs universitet/Graduate School

   Author : Ludvig Streng; Mikael Örneblad; [2021-07-06]
   Keywords : Venture capital; funding; driving forces; Sweden; determinants; regression; OLS; stock market; interest; gdp growth; corporate tax; patent applications; innovation; labor market rigidity; principal component analysis; PCA;

   Abstract : This thesis analyses the driving forces of Venture Capital (VC) funding in Sweden over the years 2001 - 2020. The driving forces of VC funding is an essential piece in understanding how well the Swedish VC industry works and fulfills its purpose in the economy. This knowledge is missing in the literature.

3. 2. Plastic contacts in particle based simulations

   University essay from Umeå universitet/Institutionen för fysik

   Author : Joacim Lindberg; [2018]
   Keywords : Algoryx; simulations; granular materials; particles; physics;

   Abstract : Granular materials, large collections of macroscopic particles, are something that is commonly found in both nature and industry. Examples of such can be sand, ore, grains, seeds or snow. Simulations of granular materials are important in many industrial cases. READ MORE

4. 3. System for measurement of cohesive laws

   University essay from Institutionen för teknik och samhälle

   Author : Tomas Walander; [2009]
   Keywords : End Notched Flexure; J-integral; Cohesive law; Finite element method; Energy release rate;

   Abstract : In this thesis an experimental method to calculate cohesive characteristics for an adhesive layer in a End Notched Flexure (ENF) specimen is presented and evaluated. The method is based on the path independent J-integral where the energy release rate (ERR) for the adhesive is derived as a function of the applied forces and the rotational displacements at the loading point and at the supports of the specimen.

5. 4. An investigation of friction graphs ranking ability regarding the galling phenomenon in dry SOFS contact : (Adhesive material transfere and friction)

   University essay from Karlstads universitet/Fakulteten för teknik- och naturvetenskap

   Author : Harald Wallin; [2008]
   Keywords : galling; friction; adhesive contact; mild adhesive; severe adhesive; abrasive; flattening; SOFS; TNO; slider on flat surface; tribology; dry; lubricated; frictional heating; acceleration; plastic zone; contact pressure; pressure; phase transformation; morphology; seizure; scoring; scuffing; cohesive forces; classification; characteristic patterns; lump; sheet damage; på kletning; friction; kontakt tryck; värme; plogning;

   Abstract : The main purpose of this project is to investigate different tool steels in terms of their ability to withstand material transfer buildup, so-called galling, occurring in SMF (sheet metal forming) operations. The ability to withstand galling is vital to optimize cost-effectiveness and increase the work tool’s effective operational time. READ MORE

6. 5. Participatory Urban Upgrading : The Case of Ezbet Bekhit, Cairo, Egypt

   University essay from KTH/Infrastruktur

   Author : Zeinab Noureddine Tag-Eldeen; [2003]
   Keywords : Informal settlement; Low-income Housing; Urban Upgrading; Community Participation; Project Evaluation; Participatory Program Evaluation; Action Planning; German-Egyptian Cooperation; Egypt; Cairo;

   Abstract : As a mega-city and the most populated city in Africa, Cairo is characterised by a high birth rate, escalating rural-urban migration and where the socio-economic services are centralized and overwhelmed, these generally poor migrants have no choice other than to create and develop their own informal shelter in the outer city areas that lay farthest from the reach of the authorities and from where they then search for better job opportunities. The expansion of these slum areas places an extra burden on the already deteriorated natural and unplanned urban environments. READ MORE
