2. 1. Crime Clusters and Safety in Underground Stations

   Author : Adriaan Cornelis Uittenbogaard; Vania Ceccato; Kate Bowers; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Safety; urban crime; crime distribution; spatial-temproal patterns; underground stations; public transport; environmental attributes; crime prevention; Real Estate and Construction Management; Fastigheter och byggande;

   Abstract : The objective of the thesis is to explore ways to assess safety in an urban context and intransport nodes. The thesis is composed of articles which aim at assessing whether safety levels vary within a city, at a public transportation network, particularly at stations, and finally making suggestions to increase safety in these environments.

4. 2. Clusters of urban crime and safety in transport nodes

   Author : Adriaan Cornelis Uittenbogaard; Vania Ceccato; Mats Wilhelmsson; Alex Hirschfield; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; safety; urban crime; space-time clusters; crime concentrations; GIS; environmental attributes; public transport; underground stations; transport nodes; crime prevention;

   Abstract : The objective of the thesis is to provide a better understanding of the safety conditions inurban environments, particularly related to those found in transport nodes, in this case,underground stations, and surrounding areas1. First, the study starts with an analysis of theoverall city, identifying concentrations of crime in the urban fabric and then focusing on thecriminogenic conditions at and around underground stations.

5. 3. Deformation and failure of rock

   Author : Kelvis del Carmen Pérez Hidalgo; Håkan Stille; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Abstract : In this doctoral thesis work the relationship between the deformation and the initiation of failure around an underground excavation was studied. In this work data from observed failure and measured deformations was used. This work is based on information obtained from laboratory test, underground field cases and numerical analysis. READ MORE

6. 4. Feasibility of HVDC for city infeed

   Author : Paulo Fischer de Toledo; KTH; []
   Keywords : ;

   Abstract : It is well recognized that direct current and direct voltageoffer special advantages for both land and sea cable systems,both with regard to power transmission capability, losses, aswell as possible transmission length due to no capacitivecurrents. As cable systems were used very early in largecities, one of the first applications considered for HVDC wasto use it for city infeed and some schemes were also built. READ MORE
