1. 1. Stellar kinematics in surveys and simulations

   Författare :Daniel Mikkola; Astronomi - Genomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Galactic dynamics; stellar dynamics; simulations; Gaia; Galactic dynamics; Stellar kinematics; Numerical simulations; Statistical methods; Solar neighborhood;

   Sammanfattning : We study stellar motions in the Milky Way with N-body simulations and large astrometric samples from ESA's Gaia mission. We identify two kinematic populations for white dwarfs in the Solar neighbourhood. We also investigate the accreted halo and reveal two new structures. LÄS MER

   Sammanfattning : This thesis consists of four self-contained essays.Essay 1 (with Olof Åslund and Matz Dahlberg): In this essay we investigate the impact of commuter train access on individual labor market outcomes. LÄS MER

4. 3. Analysis of Dynamics of the Tippe Top

   Författare :Nils Rutstam; Stefan Rauch; Hans Lundmark; Tudor Ratiu; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The Tippe Top is a toy that has the form of a truncated sphere with a small peg. When spun on its spherical part on a flat supporting surface it will start to turn upside down to spin on its peg. LÄS MER

5. 4. Local Social Exposure and Inter-Neighborhood Mobility

   Författare :Alex Giménez de La Prada; Peter Hedström; Eduardo Tapia; Petri Ylikoski; Gianluca Manzo; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ethnic segregation; residential mobility; social interdependency;

   Sammanfattning : Studies on ethnic residential segregation analyze how the inter-neighborhood mobility of individuals shapes their spatial distribution across cities. This literature has shown that the residential choices of households partly depend on the ethnic composition of their neighborhoods: higher in-group shares promote the presence of more in-group members, and vice versa.

7. 5. Modelling of Construction Safety Performance and Housing Markets in Kampala, Uganda

   Författare :Richard Irumba; Mats Wilhelmmsson; Elias Oikarinen; KTH; []
   Nyckelord :accidents; construction industry; housing markets; spatial rgression modelling; system dynamics; Real Estate and Construction Management; Fastigheter och byggande;

   Sammanfattning : The construction industry in Uganda is characterized by a high incidence rate of accidents. During the late 1990s, an annual average of 49 accidents were reported in the construction industry while during the period 2001 to 2005, the annual average for this sector was 103 cases. LÄS MER
