We consider an optimization problem of joint link rate assignment and transmission scheduling in wireless mesh networks. We assume that each radio link uses (when active) one selected link-dependent modulation and coding scheme. For finding an exact optimum, the problem requires a complicated branch-and-price algorithm that becomes excessively time consuming for networks of practical size. Therefo

Renewable portfolio standards (RPS) and minimum price standards are two systems to foster the market dissemination of renewable energies in the electricity sector. Transaction Cost Economics brings forward that the contractual relations in real structures have to be investigated to judge on the efficiency of governance structures. This paper seeks to do so by comparing governance structures create

Wireless access technologies such as UMTS with HSPA extensions, WiMAX, and Flash-OFDM and the convergence towards next generation heterogeneous networks enable the realization of always best connected scenarios. As the resulting heterogeneous networks become easier to access and more reliable to depend on, novel telemedicine services such as vehicular emergency applications emerge. Due to their li

Popular Abstract in Swedish Strax efter andra världskriget bestod den judiska befolkningen i Sverige av cirka 13.000 personer. Det var mindre än en procent av landets dåvarande befolkning, men för den judiska befolkningen i Sverige var det en ökning med 65 procent jämfört med tiden före andra världskriget. Denna studie handlar om vilka historiska händelser som betonats hos den svenska judiska befoThe thesis deals with the queswtion of which historic events have been emphasised amog Jewish people in Sweden after the Second World War. The founding of Israel is the point of departure and the termins ad quem is ten years further. The basic source material for the study is Judisk krönika ("Jewish Cronicle"), a periodical which was launched in 1932. In the 1950s Judisk krönika assumed a special

Popular Abstract in Swedish Skador på kroppens ligament och senor är vanliga och medför, förutom mycket lidande för den drabbade, ett stort samhällsekonomiskt problem. Speciellt stora problem orsakar korsbandsskador i knäleden och böjsenskador inom fingrarnas senskideområde. Både ligament och senor är uppbyggda av extracellulärt matrix som består framför allt av kollagen men dessutom av icke-kollaThe poor healing capacity of the anterior cruciate ligament and the development of postoperative adhesions, restricting tendon gliding, are two important clinical problems regarding different, although related, aspects of posttraumatic connective tissue reactions. The aim of this study was to gain more knowledge about the process of ligament and tendon healing at the cell and molecular levels and
