1. 1. Recharging Future Mobility : Understanding Digital Anticipatory UX through Car Ethnographies

   Författare :Thomas Lindgren; Vaike Fors; Magnus Bergquist; Martin Berg; Robert Broström; Marc Hassenzahl; Högskolan i Halmstad; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Anticipatory; User Experience; Design Ethnography; Entanglement; Digitalisation;

   Sammanfattning : Cars have created many positive experiences for people by providing them freedom of mobility, exciting driving thrills and status in society. However, cars are also known to create problems such as pollution, traffic congestion and accidents. LÄS MER

3. 2. Essays on intergenerational income mobility, geographical mobility, and education

   Författare :Stefanie Heidrich; Thomas Aronsson; David Granlund; Magnus Wikström; Markus Jäntti; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; optimal taxation; social norms; intergenerational mobility; regional analysis; multilevel model; child human capital development; moving costs; simulation of income paths; lifetime income; nationalekonomi; Economics;

   Sammanfattning : This thesis consists of an introductory part and the following four self-contained papers:In Paper [I] we analyze the implications of social identity and self-categorization for optimal redistributive income taxation. A two-type model is supplemented by an assumption that individuals select themselves into social categories, in which norms are formed and education effort choices partly depend on these norms.

4. 3. Heterogeneous Innovation and Labour Mobility

   Författare :Ding Ding; Pontus Braunerhjelm; Stam Erik; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; labor mobility; knowledge spillover; organizational learning; entrepreneurship; heterogeneous innovation; Nationalekonomi; Economics;

   Sammanfattning : Knowledge is a necessary and critically important factor in generating growth and increased prosperity. The extent to which such effects are materialized depends however on its diffusion and how it transcends into innovation, entrepreneurship and growing firms. LÄS MER

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

   Författare :Martin von Haartman; Mikael Östling; Cor Claeys; KTH; []
   Nyckelord :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;

   Sammanfattning : 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.

7. 5. Mobility and Multi-channel Communications in Low-power Wireless Networks

   Författare :António Gonga; Mikael Johansson; Riku Jäntti; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobility; Multi-channel communications; Neighbor Discovery; MAC Protocols; Low-power Wireless Networks; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : The prospect of replacing existing fixed networks with cheap, flexible and evenmobile low-power wireless network has been a strong research driver in recent years.However, many challenges still exist: reliability is hampered by unstable and burstycommunication links; the wireless medium is getting congested by an increasingnumber of wireless devices; and life-times are limited due to difficulties in developingefficient duty-cycling mechanisms.
