Power supply monitoring for wireless sensor platforms

Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.

Gymnasieelevers informationskompetens : En studie i sju klasser i gymnasiets år 3

This master's thesis examines information literacy and students in secondary education. The study is framed within a sociocultural perspective of learning and the method used is questionnaires. The major question posed is how and where students seek information. Other questions are if the students critically evaluate and analyse in­formation sources and if teachers and school librarians cooperate with each other in order to help the students with their assignments.The findings indicate that most students regard information seeking as fact-finding or finding the right an­swers to the question. Only one third of students experienced information seeking as seeking and using informa­tion for understanding a topic.

Informationspark? Informationsstrukturerna hos bioteknikföretagen på Ideon

This thesis deals with information provision to the knowledge intense biotechnology businesses of Ideon Science Park in Lund, Sweden. Previous research concerning the information needs of Science Park companies has been conducted from the information provider s perspective. Instead, we apply a user perspective to find out what information needs these companies have, and how they prefer to acquire information. Central terms are: information, -needs, -acquisition, -consciousness, -strategy, small and medium sized enterprises, scientists and engineers, information (resources) management, networks, tacit knowledge, knowledge transfer and innovative milieux. The companies need scientific and business information; the latter is easily obtained within Ideon.

Do prey-animals in zoos need predators?

Today is one of the goals with zoos to conserve endangered species and some animals may also become reintroduced. But behaviours can change in generations of captive animals because of environments that differ from the wild. Animals must then be prepared before being reintroduced and predator training enhances the animal?s chance to survive in the wild. When training animals to avoid predators it is often necessary to use frightening stimuli.

Den digitala slöjan : En kvalitativ intervjustudie om Facebook som scen för den svensk-muslimska tjejens framträdande

The study is based on a qualitative method which consists of nine interviews with Swedish Muslim girls between the ages 17-23 and who use Facebook daily.The study is based on the view of Facebook as a scene where individuals can perform for an audience. I have used Erving Coffman?s dramaturgical perspective that explains why individuals appear in an appropriate manner to achieve confirmation from their audience. I also used theories about identity construction, community and the theory about how individuals create a social presence online.

Undersökningsmetodik för klorerade lösningsmedel i marken

Chlorinated solvent are volatile organic substances that can be harmful for humans and for the environment. Examples of common chlorinated solvents are perchloroethene, PCE, and trichloroethene, TCE. Chlorinated solvents appear as contaminants in soils primarily where they have been used as washing fluids in dry-cleaning facilities or as degreasers in metal industries. Chlorinated solvents are DNAPLs (dense non-aqueous phase liquids), which means that they are not easily dissolved in water and that they sink to the bottom of the aquifer. Adsorption to soils is low so chlorinated solvents are mobile in soils.
