This paper presents results for vehicle-to-vehicle channel characterization based on measurements conducted for the merging lane scenarios on a highway. We present power delay profiles as well as channel gains and analyze important propagation mechanisms to see the impact of line-of-sight (LOS) and the antenna radiation pattern on the total received power. It is found that the absence of LOS and s
This paper presents the characterization of forced cooling channels with three different shapes which are applied in traction motors mounted in Hybrid Vehicles (HEVs) or Zero Emission Vehicles (ZEVs). Generally, there are two different positions of forced cooling channels in electric motors. One way is by drilling holes or cutting cooling channels inside the housing, which is called indirect cooli
Det finns två huvudsakliga svar på frågan varför forskning och utveckling, F&U, i området digitala läromedel är viktig. Det första är relativt uppenbart: Det produceras idag allt fler digitala läromedel som används i ökad utsträckning i skolan. För att kunna ta fram digitala läromedel av hög kvalitet krävs forskning och utveckling. Det andra och mindre uppenbara svaret är att digitala läromede
We present a method for the estimation of the distribution of the quasi-static hogging-bending moment for a floating body. Starting points of this study are temporal characteristics of the sea state. The approximation is deduced from the estimation of the joint distribution of crest amplitude and crest length. The quality of the model is investigated by comparing computed distributions with empiri
There are water vapour condensation and two-phase flow in plate heat exchangers when they are used as condensers. Water phase change and flow dynamics modelling is an important but complicated task due to large change in water physical/transport properties across the water liquid-vapour interface boundary. In particular, singular-link behaviour in governing equations is present due to the large st
Today embedded system development is a complex task. To aid the engineers new methodologies and languages are emerging. During the development the system is modeled using different tools and languages. Transformations between the models are traditionally done manually. We investigate the automation of this process, specifically we are looking at automatic UML to SystemC transformation. In this pap
This paper presents the preliminary evaluation of different powered-wheelchair control modes for individuals with severe motor impediments. To this end, a C400 Permobil wheelchair has been updated with a control command communication interface and equipped with a scanning laser sensor to carry out the automation algorithms that are part of the robot operating system framework. A pilot test was per
Availability of safe, edible food is essential. Food shortage has caused many wars and encouraged people to try to preserve food for a longer time, allowing storage and transport, often in some kind of package/container. The USA showed the way in developing the food sector and already prior to the 2nd World War they had self-service stores filled with packed goods. Europe, however, had to wait to
This paper presents a new and practical simulation interface to design and analyze lower-limb prosthetic devices. The proposed tool simulates the gait of a lower limb amputee using a desired prosthetic device. It allows the analysis of simple passive devices or the testing of control algorithms for active prostheses. The results presented in this paper correspond to the use of this tool to test a
This paper describes national cooperation in Sweden launched by its universities and authorities, aimed at improving geodata education. These initiatives have been focused upon providing common access to geodata, the production of teaching materials in Swedish and organizing annual meetings for teachers. We argue that this type of cooperation is vital to providing high quality education for a poor
Stability of some decentralized traffic signal control policies for urban traffic networks is studied. It is proven that, whenever the arrival rates belong to a certain region -which is the largest where stability is possible- the resulting traffic network dynamics admit a globally asymptotically stable equilibrium. The results rely on the use of some entropy-like Lyapunov functions previously con
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
Since the development of real-time PCR, the technology has been widely applied in the field of diagnostics. In comparison with conventional PCR it has opened up the possibility of accurate quantification of microorganisms in clinical, environmental and food samples. When employing real-time PCR and absolute quantification in biological samples, five important requirements should be fulfilled, name
The need to reduce CO2 emissions from fossil-fuel based power production creates the need for new power plant solutions where the CO2 is captured and stored or reused. Oxygen Transfer Membrane (OTM) is the key component of oxy-fuel combustion processes as pure oxygen is usually required to process reactions (e.g. Natural Gas Combined cycle NGCC, Pulverised Coal-fired power plants PC-plants, Integr
