1. 1. Synthesis of nucleotide, peptide and lipid containing molecular tools for life science studies

   Författare :Esmail Yousefi Salakdeh; J.H. Van Boom; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; organisk kemi;

   Sammanfattning : This thesis is based on five parts. The first and second chapters describes two synthetic routes, employing different protecting group strategies for synthesis of uridine 3'-(ethyl, 2-ethoxyethyl, 2-chloroethyl, 2,2-dichloroethyl and 2,2,2-trichloroethyl) phosphate. LÄS MER

3. 2. Management of technology in the process industries:  Matching market and machine

   Författare :Peter Samuelsson; Pär Jönsson; Rob Boom; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process industries; manufacturing; innovation; configuration; strategizing; capability; configuration modelling; process industries; production system; physical modelling; AOD; converter geometry; injection; mixing times; electric arc furnace; EAF; post-combustion; high-impedance; network disturbances; operational results; Metallurgical process science; Metallurgisk processvetenskap;

   Sammanfattning : The process industries span multiple industrial sectors and constitute a substantial part of the entire manufacturing industry. Since companies belonging to this family of industries are often very asset intensive, their ability to respond to changes is often limited in the short term. LÄS MER

4. 3. Studies on High Alumina Blast Furnace Slags

   Författare :Amitabh Shankar; Seshadri Seetharaman; Rob Boom; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process engineering; Metallurgisk processteknik;

   Sammanfattning : In the present work, viscosities and sulphide capacities of high alumina blast furnace slags were investigated. The systems investigated were four component CaO-SiO2-MgO-Al2O3 quaternary system, CaO-SiO2-MgO-Al2O3-TiO2 and CaO-SiO2-MgO-Al2O3-CaF2 quinary systems. LÄS MER

5. 4. Stiffness modification of tensegrity structures

   Författare :Seif Dalilsafaei; Anders Eriksson; Karl-Gunnar Olsson; KTH; []
   Nyckelord :tensegrity; boom; finite element analysis; genetic algorithm; flexibility analysis; active structure; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Although the concept of tensegrity structures was invented in the beginning of the twentieth century, the applications of these structures are limited, partially due to their low stiffness. The stiffness of tensegrities comes from topology, configuration, pre-stress and initial axial element stiffnesses. LÄS MER

7. 5. Kinematic Control of Redundant Knuckle Booms with Automatic Path Following Functions

   Författare :Björn Löfgren; Jan Wikander; Arto Finland Helsinki University of Technology Visala; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic manipulator; redundancy; kinematic control; local optimization; knuckle boom; forest machine; forwarder; boom tip control; joystick control; simulations; path following; Construction engineering; Konstruktionsteknik;

   Sammanfattning : To stay competitive internationally, the Swedish forestry sector must increase its productivity by 2 to 3% annually. There are a variety of ways in which productivity can be increased. One option is to develop remote-controlled or unmanned machines, thus reducing the need for operator intervention. LÄS MER
