The aim of this work is to propose a framework for providing QoS routing in MANETs. The proposed framework uses local information of nodes such as node's speed, buffer, and power to select path for routing. Deploying these information, more stable paths are selected and hence QoS routing parameter could be satisfied. Moreover, routing performance has been improved, especially in terms of end-to-en
A comparative experimental investigation has been performed, comparing the emissions from a synthetic jet fuel and from Jet AI. In the investigation, the unburned hydrocarbons were analyzed chemically and the regulated emissions of NOX, CO and HC were measured. All combustion tests were performed under elevated pressures in a gas turbine combustor rig. A Swedish company, Oroboros AB, ha
Popular Abstract in Swedish Cancer är på cellnivå en genetisk sjukdom, i det avseendet att typiska egenskaper för cancerceller, t ex okontrollerad celldelning samt abnorm känslighet för yttre regulatoriska signaler, uppkommer genom förvärvade och ibland ärftliga förändringar, s k mutationer, i cellens arvsmassa. Hur mutationerna uppstår är bara till viss del känt. Somliga förändringar beror på strAcquired genetic alterations, of which many are visible on the chromosome level, are believed to be necessary for tumorigenesis, and most tumors display characteristic patterns of recurrent structural and numerical aberrations. However, two of the most frequently occurring chromosome mutations in malignant and benign solid tumors, i.e., trisomy 7 and rearrangements of 12q13-15, have recently been
Popular Abstract in Swedish Intensifieringen av jordbruket sedan 1950-talet har lett till en ökad matproduktion men också orsakat miljöproblem så som förlust av biologisk mångfald, jorderosion, övergödning, ökade utsläpp av växthusgaser samt föroreningar av bekämpningsmedel. Det är därför nödvändigt att utveckla ett mer hållbart jordbruk samtidigt som vi upprätthåller den globala matförsörjningen Agricultural intensification has raised the global food production but also caused major concerns about environmental and health effects, including contamination by pesticides. Pesticide applications may induce toxicity not only on the target pest species but especially on non-target species. Hence we need to replace pesticides with management that promote organisms that suppress pest population.
Popular Abstract in Swedish Närmare 30.000 svenskar drabbas årligen av stroke (slaganfall). I ungefär 85 % av fallen är orsaken en blodpropp i ett av hjärnans kärl s.k. hjärninfarkt. En avstängning av blodflödet orsakar en snabbt insättande förlust av funktionen i det drabbade området, t.ex. halvsidig förlamning, bortfall av delar av synfältet liksom störning av olika högre hjärnfunktioner såsom mAbstract Stroke is the third leading cause of death in the western world, and the number one cause of disability. 85% of all strokes are ischemic. Most stroke survivors will experience recovery of function. The mechanisms behind this improvement are partly unknown, but may involve elements of both compensation and restoration. Exposure to an enriched environment (EE) that stimulates social interac

This chapter explores what L2 learners' gestures reveal about L2 grammar. The focus is on learners’ difficulties with maintaining reference in discourse caused by their incomplete mastery of pronouns. The study highlights the systematic parallels between properties of L2 speech and gesture, and the parallel effects of grammatical development in both modalities. The validity of a communicative acco
This book presents an economic analysis of the causes and consequences of institutional change in ancient Athens. Focusing on the period 800-300 BCE, it looks in particular at the development of political institutions and taxation, including a new look at the activities of individuals like Solon, Kleisthenes and Perikles and on the changes in political rules and taxation after the Peloponnesian Wa
This paper deals with the construction and orbital stabilization of periodic solutions for a particular underactuated mechanical system with 2 degrees of freedom, the Furuta pendulum. It is shown that if a desired periodic motion is described by constraints imposed on the total energy of the system and on the value of the directly actuated variable, then this periodic motion can be constructed and

Popular Abstract in Swedish Syftet med avhandlingen var att undersöka om och hur lek påverkar arbetsplatsens kreativitet. Forskning har visat att leken är viktig för barns kreativitet, men leken kan också gynna vuxnas kreativitet. En vanlig definition av kreativitet är att den innebär skapandet av något som är både nytt och nyttigt. När lek definieras beskrivs den som ett mentalt tillstånd eller eThis thesis investigates how play may benefit creativity in organizational contexts. Play and playfulness have previously been linked to creativity in children and adults, but empirical organizational research is scarce. A widely accepted definition of creativity is that it involves the production of something that is both novel and appropriate. Play is defined as a behavioral approach that is cha
