This paper discusses design and measurements of a flexible Viterbi decoder fabricated in 130-nm digital CMOS. Flexibility was incorporated by providing various code rates and modulation schemes to adjust to varying channel conditions. Based on previous trade-off studies, flexible building blocks were carefully designed to cause as little area penalty as possible. The chip runs down to a minimal co

A new algorithm for clustering is presented --- the Distributed Clustering Algorithm (DCA). It is designed to be incremental and to work in a real-time situation, thus making it suitable for robotics and in models of concept formation. The DCA starts with one cluster (or rather prototype at the center of the cluster), successively adding prototypes and distributing them according to data density u

Dynamical flow networks with heterogeneous routing are analyzed in terms of stability and resilience to perturbations. Particles flow through the network and, at each junction, decide which downstream link to take on the basis of the local state of the network. Differently from single-commodity scenarios, particles belong to different classes, or commodities, with different origins and destination

Det som här följer är en dokumentation av en del av min rörelseundervisning på Teaterhögskolan i Malmö. Detta arbetsblock möter eleven under termin två och tre. Målet är att kunskaper och insikter ur detta arbete ska kunna integreras i det sceniska arbetet, något som naturligtvis inte sker automatiskt, utan kräver mycket vidare arbete. Detta är inte ett försök till systembygge, att beskriva allt d

A feedback-based scheme for cooperative content distribu- tion for mobile systems aimed at reducing energy and li- censed spectrum usage is presented. The paper is motivated by the problems in implementing peer-to-peer based content distribution in mobile networks due to the risks of unfair en- ergy expenditure. A technique for incentivizing cooperation and for enforcing agreements between peers i

The required moment of inertia for steel plate girders is commonly provided by using relatively slender webs to achieve high strength-to-weight ratio. A large part of the shear capacity of such plate girders depends on the post-buckling reserve strength of the web panels due to the diagonal tension field mechanism. The effectiveness of the tension field significantly depends on geometrical and mec

Popular Abstract in Swedish Efter hand som människans livslängd ökar, ökar också frekvensen av och dödligheten i cancer. För att cancer ska kunna överleva och inte selekteras ut och attackeras av kroppens immunförsvar måste den anpassa sig till och styra sin omgivning. Ett sätt att motarbeta cancern är att angripa proteiner som är nödvändiga för cancerns överlevnad. Naturprodukten galiellalakton hCancer cells use normal cell signalling pathways in a proliferative fashion in order to prolong their own survival. Inhibition of one of the major signal proteins, STAT3 (Signal Transducer and Activator of Transcription 3) has previously been shown to induce apoptosis. Galiellalactone, a fungal metabolite, inhibits STAT3, thus presenting a potential lead for cancer treatment. The inhibition is bel
