1. 16. Broadband Wireless OFDM Systems

   Författare :Maxime Flament; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; channel model; 4th Generation Wireless 4GW ; shadowing; MMIC; WLAN; scenarios; mobile data; OFDM; turbo codes; propagation; license-exempt bands; coding; 60 GHz channel; broadband wireless; interference; Virtual Cellular Network VCN ; front-end;

   Sammanfattning : While the readiness of the telecommunication market and the users' need for broadband mobile data are not currently noticeable, a set of presented megatrends and scenarios suggest that broadband mobile data access will develop quickly in the next ten years. Identification of the potential frequency bands offering cheap and trouble-free wireless infrastructure is therefore an important step towards the definition of new air interfaces. LÄS MER

3. 17. Mechanical and Electrical Properties of Mesoscopic Wires

   Författare :Sara Blom; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rabi oscillations; conductance quantization; free electron model; mesoscopic; microwave; channel; force fluctuations; adiabatic; nanowire;

   Sammanfattning : The mechanical and electrical properties of mesoscopic wires have been studied theoretically using a free electron model. When a mesoscopic wire is elongated the conductance decreases in steps. Each step is accompanied by an abrupt change in the force. LÄS MER

4. 18. Exploring the Scalability and Performance of Networks-on-Chip with Deflection Routing in 3D Many-core Architecture

   Författare :Awet Yemane Weldezion; Hannu Tenhunen; Lirong Zheng; Tapani Ahonen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alpha-model; Average distance; B-Model; NoC; Zero-load predictive model; deflection routing; q-routing;

   Sammanfattning : Three-Dimensional (3D) integration of circuits based on die and wafer stacking using through-silicon-via is a critical technology in enabling "more-than-Moore", i.e. functional integration of devices beyond pure scaling ("more Moore"). LÄS MER

5. 19. Rearranging a business model towards market orientation : strategic and operational dimensions and the impact of E-commerce

   Författare :Daniel Kindström; Linköpings universitet; []
   Nyckelord :Business model; market orientation; strategic positions; operative platforms; E-commerce; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

   Sammanfattning : The overall purpose of this thesis is to explore and describe the rearrangements of a company (changes), from a business model perspective, as it attempts to strategically reorient itself towards market orientation. E-commerce, and more specifically, the impact of e-commerce in this process will be explored. LÄS MER

7. 20. Phenomenology of Higgs Bosons Beyond the Standard Model

   Författare :Glenn Wouda; Rikard Enberg; Gunnar Ingelman; Johan Rathsman; Rui Santos; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Particle physics; The Standard Model; Higgs bosons; Higgs mechanism; Beyond the Standard Model; Two Higgs Doublet Models; Charged Higgs boson; Higgs decays; Supersymmetry; Renormalization; LHC; Collider constraints; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

   Sammanfattning : After a long history of searches, a Higgs boson H was discovered by the ATLAS and the CMS experiments at the Large Hadron Collider (LHC) in 2012. Its properties fit well the ones predicted by the Standard Model (SM) of particle physics. However, the SM can not explain other established properties of Nature, such as the existence of Dark Matter. LÄS MER
