Hydrogen-fuelled technologies for home heating and cooking may provide a low-carbon solution for decarbonising parts of the global housing stock. For the transition to transpire, the attitudes and perceptions of consumers must be factored into policy making efforts. However, empirical studies are yet to explore potential levels of consumer heterogeneity regarding domestic hydrogen acceptance. In r
Popular Abstract in Swedish Mekanisk ventilation kan medföra "ventilationsinducerad lungskada" (VILI), som kan öka sjuklighet och dödlighet i samband med akut lungskada (ALI). Flera ventilationssätt har föreslagits för att undvika VILI, men inte slutgiltigt utvärderats. En princip är att öka alveolär ventilation och CO2-elimination genom att minska ventilationen av de skadliga rummet, dead space. Ventilator-induced lung injury (VILI) may contribute to morbidity and mortality of acute lung injury (ALI). Lung protective ventilation (LPV), that reduces VILI, may involve low tidal volume (Vt). Particularly low Vt is possible if dead space ventilation is reduced e.g. by aspiration of dead space gas (ASPIDS). ASPIDS implies that gas rich in CO2 during expiration is aspirated through a separate c
Popular Abstract in Swedish Den största källan till läkemedelsrester i vattenmiljön är utgående renat avloppsvatten från våra kommunala reningsverk. Läkemedel är utvecklade för att ha olika typer av biologiska effekter. Vilka dessa är i människan är relativt välkänt, medan effekterna på vattenlevande organismer och andra djur till stor del är okända. Detta i kombination med deras resistens mot de The discharge of effluents from wastewater treatment plants (WWTPs) is considered to be the major source of residual pharmaceuticals frequently found in aquatic environments. The complex nature of such compounds tends to make conventional biological treatments aimed at their removal ineffective. The present thesis concerns the removal of 62 different active pharmaceutical ingredients commonly dete
Traditionally, control loops are closed using periodic sensing and actuation. When communication resources are scarce, however, much may be gained from transmitting only when something important has happened in the loop. This paper presents a simple model of the interference between event-based control loops caused by sharing a common medium, based on the coupled dynamics of a Markov chain represe
