2. 1. Struggle for Mobility : Risk, hope and community of knowledge in Eritrean and Ethiopian migration pathways towards Sweden

   Author : Tekalign Ayalew Mengiste; Erik Olsson; Shahram Khosravi; Ninna Nyberg Sørensen; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; refugee journey; irregular migration; vulnerability; hope; human smuggling; knowledge; community; mobility; migration infrastructure; diaspora; socialantropologi; Social Anthropology;

   Abstract : On the basis of the ethnographic fieldwork conducted in Sweden, Italy, Sudan and Ethiopia during 2013–2015, this study examines the motivations, organizations and impact of overland migratory journeys from Ethiopia and Eritrea across the Sahara Desert and Mediterranean Sea to Sweden. The analysis involves the exploring of how migrants strive to prepare, manage and survive the multiple risks and structural barriers they encounter: the exits from Eritrea and Ethiopia, negotiations and contacts with various brokers and facilitators, organized crime and violence, restrictive border controls, passage through the Desert and high Sea and finally, ‘managing the asylum system in Sweden’.

   Abstract : Stockholm County is a post-industrial Swedish region characterized by high levels of mobility and technologization as well as ethnic and religious diversity. Among its religious minorities exist various strands of charismatic Christianity, some of which originate from the Pentecostal revival of the early 20th century and some of which belong to more recent movements.

5. 3. Low-frequency noise characterization, evaluation and modeling of advanced Si- and SiGe-based CMOS transistors

   Author : Martin von Haartman; Mikael Östling; Cor Claeys; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MOSFET; SOI; SiGe; strain; high-k; metal gate; 1 f noise; low-frequency noise; mobility fluctuations; phonons; number fluctuations; traps; buried channel; mobility; substrate bias; Electronics; Elektronik;

   Abstract : A wide variety of novel complementary-metal-oxide-semiconductor (CMOS) devices that are strong contenders for future high-speed and low-noise RF circuits have been evaluated by means of static electrical measurements and low-frequency noise characterizations in this thesis. These novel field-effect transistors (FETs) include (i) compressively strained SiGe channel pMOSFETs, (ii) tensile strained Si nMOSFETs, (iii) MOSFETs with high-k gate dielectrics, (iv) metal gate and (v) silicon-on-insulator (SOI) devices.

6. 4. Truck Tyre Vibration Behaviour. Measurements and High Frequency Modelling

   Author : Penka Dinkova; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration response; mobility measurements; truck tyre; heavy vehicle; tyre-road noise; tyre; driving point mobility; transfer mobility; tire; vibration prediction; model;

   Abstract : To facilitate tyre-road noise prediction, a computationally efficient high frequency tyre model is needed. Such models are always a compromise between the desired accuracy and the need for simplicity. In addition the accuracy of models is often limited by the quality of the input data available.
