1. 1. 3D Scan Matching for Mobile Robots with Application to Mine Mapping : Licentiate Thesis

   Författare :Martin Magnusson; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

   Sammanfattning : This thesis is concerned with three-dimensional scan registration, in particular of underground mine tunnels. Registration of partial range scans is an essential part of building 3D maps, and autonomous creation of reliable maps is a first step towards autonomous mining vehicles. LÄS MER

3. 2. On the Cost of Capital, Profits and the Diffusion of Ideas

   Författare :Has van Vlokhoven; Timo Boppart; Per Krusell; Jan Eeckhout; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cost of capital; Profit share; Capital share; Labor share; Markups; Marginal products; International capital markets; Firm life cycle; Firm entry; Technology diffusion; Search; Networks; Productivity distribution; Economics; nationalekonomi;

   Sammanfattning : Estimating the Cost of Capital and the Profit Share Compensation of the factor of production capital is not directly observed since most firms own part of their capital stock. I develop a new method to estimate capital compensation. LÄS MER

4. 3. Walk this way : Verbs of motion in three Finno-Ugric languages

   Författare :Torbjörn Söder; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Finno-Ugric languages - general; Hungarian; North Khanty; verbs of motion; semantics; etymology; lexical category; Finno-Ugric; prototype; deixis; dialects; Finsk-ugriska språk - allmänt; Finno-Ugric languages; Finsk-ugriska språk; Finsk-ugriska språk; Finno-Ugric Languages;

   Sammanfattning : The verbs of motion in North Khanty, North Saarni and Hungarian, three genetically related, but geographically, culturally and historically separated languages, are analysed from a synchronic and diachronic point of view. The study is based on material deriving from informants and written sources in each language. LÄS MER

5. 4. Surface integrity on post processed alloy 718 after nonconventional machining

   Författare :Jonas Holmberg; Tomas Beno; Anders Wretland; Johan Berglund; Mikael Olsson; RISE; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 718; Non-conventional machining; post processing; surface integrity; Microstructure; Residual stress; Electron back scattering diffraction; Material removal rate; Manufacturing; Surface and Joining Technology; Bearbetnings-; yt- och fogningsteknik; Production Technology; Manufacturing and materials engineering;

   Sammanfattning : There is a strong industrial driving force to find alternative production technologies in order to make the production of aero engine components of superalloys even more efficient than it is today. Introducing new and nonconventional machining technologies allows taking a giant leap to increase the material removal rate and thereby drastically increase the productivity. LÄS MER

7. 5. High volumetric machining strategies for superalloy gasturbine components : Comparing conventional and nonconventional machining methods for efficient manufacturing

   Författare :Jonas Holmberg; Johan Berglund; Anders Wretland; Tomas Beno; Joel Andersson; Sten Johansson; RISE; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 718; High volumetric machining; Conventional and Nonconventional machining; Material removal rate; Post processing; surface integrity; Residual stress; Microstructure; Deformation; Manufacturing; Surface and Joining Technology; Bearbetnings-; yt- och fogningsteknik; Production Technology;

   Sammanfattning : There is a strong industrial driving force to find alternative manufacturing technologies in order to make the production of aero engine components of superalloys even more efficient than it is today. Introducing new and nonconventional machining technologies, as well as enhanced utilisation of today's high volumetric manufacturing, allows taking a leap to increase the material removal rate and the productivity.
