The free Modelica library ThermoFluid was developed for simulation ofthermo-hydraulic applications, both for single-species applicationslike the water-steam cycle in a thermal power plant and formulti-species applications with gas mixtures. It has demonstratedits flexibility for modeling thermodynamic and process applicationsin a variety of industrial and academic projects. This articledescribes h

In a masterly book, Roderick MacFarquhar and Michael Schoenhals explain why Mao launched the Cultural Revolution, and show his Machiavellian role in masterminding it (which Chinese publications conceal). In often horrifying detail, they document the Hobbesian state that ensued. The movement veered out of control and terror paralyzed the country. Power struggles raged among Lin Biao, Zhou Enlai, De

Popular Abstract in Swedish Jorden i vår natur är en mycket komplex miljö som innehåller en mängd olika organismer. Bland dessa är bakterier och svampar av störst betydelse eftersom de står för en stor del av nedbrytningen av olika ämnen. Jordbakterierna utför t.ex. många av ämnesomvandlingarna av kväve, svavel och fosfor i marken. Nedbrytningen frigör näringsämnen som sedan kan utnyttjas av växteThe soil bacterial community is under the constant influence of its environment. Changing any of the factors affecting the bacterial community will induce a selection pressure which, with time, will change the community. In this work the effect of changing the temperature or pH on the soil bacterial community was studied. Measurements using the [3H]-thymidine incorporation technique showed that th

Popular Abstract in Swedish Intestinal ischemi/reperfusion (I/R) är ett potentiellt mycket allvarligt tillstånd som kan bero dels på direkt ocklusion av mesenteriella kärl, men även vara sekundärt till andra tillstånd med nedsatt visceral cirkulation, som exempelvis chock eller akut pankreatit. Trots korrekt och även initialt framgångsrik behandling av den bakomliggande orsaken till I/R-tillståndeIntestinal ischemia and reperfusion (I/R) is a potentially life-threatening condition, sometimes leading to a systemic inflammatory response and the potential development of the multiple organ dysfunction syndrome. The overall aim of the thesis was to study the effects of intestinal I/R on pulmonary function with special emphasis on removal of excess alveolar fluid, pulmonary endothelial barrier p

Software Configuration Management (SCM) is an important support activity in software development. However, its transparent nature as a service that makes life easier for others and as an insurance against disasters, often makes it difficult to justify investments in tools and processes that apparently do not have any direct return. We have made a first step towards establishing a model for showing

Ultra-wideband (UWB) communication is a potential technique for future high-speed networks. In this paper, we investigate low complexity signal detection approaches for OFDM based UWB systems. In particular, we develop practical approaches for channel estimation and interference suppression. Computer simulation results show that these techniques can be effectively used in OFDM based UWB systems fo
