Information from performed risk and vulnerability analyses, evaluation of responses in relation to actual emergencies etcetera can be very useful in efforts directed at preventing, mitigating and/or preparing for future emergencies. This thesis focuses on the development of methods for such analysis and evaluation. A general process for systematic design of methods is introduced and discussed and
Large eddy simulations are performed for a single- and multiphase jets in crossflow (JICF). The multiphase JICF are compared to the single-phase case for the same momentum and mass flow ratios but with droplets of different sizes. Multiphase JICF have stronger counter-rotating vortex pairs (CVPs) than a corresponding single-phase JICF. Moreover, their trajectories are higher and their induced wake
Vem är Clint Eastwood? Han har själv sagt: "Det finns ingenting som är jag. Jag är ingenting i mig själv." Min korta bio/monografi tar honom på orden och ignorerar alla rykten och skandaler för att fokusera på den Clint Eastwood vi otvivelaktigt känner: mannen på bioduken, stjärnan, den politiska ikonen. Boken blir en resa genom 80 år av amerikansk historia och filmhistoria, en historia som format

This book chapter discusses some trends in critical theory and activist aesthetics in contemporary feminist performing arts in Sweden. The 2000s have witnessed at least two “turns” in feminist theory, namely the affective turn and the social, or as it is called here, the solidarity turn. The status of poststructuralist theory has been widely debated and Marxist, class-based analyses have returned
The study identifies three stages in surrealism's view of the imaginary (partly consecutive, partly coexisting): The imaginary as being something real in itself The imaginary as being materially real The imaginary as being a self-realising force

This paper presents a study of the so called far field approximation to the problem of determining both the direction to a number of transmittors and the relative motion of a single antenna using relative distance measurements. The same problem is present in calibration of microphone and wifi-transmittor arrays. In the far field approximation we assume that the relative motion of the antenna is sm
This paper explores the effects of roadway and roadside environment characteristics on the speed chosen by drivers. This work is an observational study of 272 segments of two lane roads in Connecticut. Data was collected for lane width, shoulder width, road width, presence of curbs and edge delineation types. For the roadside environment the following variables were also measured: presence of side
Electroactive polymers (EAP) deform under electric fields and an advantage of EAP is that they may undergo deformations much larger than those capable by electroactive ceramics, however at comparatively much lower forces. As common for polymers, EAP exhibit time-dependent material behavior, i.e. an electro-viscoelastic effect. Modeling of this behavior is discussed. The forward motion problem foll
Road safety is one of the most important emerging applications envisioned for Vehicular Ad hoc Networks (VANETs). Generally, such applications involve the broadcast of safety messages, consisting of beacons transmitting vehicles' state (e.g. position and velocity) with a regular period, as well as emergency messages warning about unexpected critical events. From the perspective of safety, the appl
The following text addresses the ecological and cultural significance of the threats affecting the honey-bee, and which are becoming apparent through the unusual and sometimes drastic death rates of bee colonies. General research conducted on this problem largely agrees that the threats to bees are a syndrome that has a multifactorial nature and anthropogenic origin. In face of a plethora of relev
