People who have visual impairments may have difficulties navigating freely and without personal assistance, and some are even afraid to go out alone. Current navigation devices with non-visual feedback are quite expensive, few, and are in general focused on routing and target finding. We have developed a test prototype application running on the Android platform in which a user may scan for map in
We investigate how users on a prominent forum for white supremacists interpreted and framed two seminal events for the far-right in the U.S., the elections of Obama in 2008 and Trump in 2016. These cases precipitated dramatic shifts in the far-right alliance and conflict structure. We combine computational methods and qualitative analysis on a corpus of over ten million posts on Stormfront.org to
Om platser verkligen är av betydelse, vilket ekonomiska geografer anser, då måste de vara som mest betydelsefulla för de människor vars liv utspelar sig på dessa platser, och upplever världen, materiellt kan kulturellt, genom den. När en kris och efterföljande osäkerheter drabbar en plats så påverkar detta främst människorna som kallar denna platsen för sitt hem. Ibland till den grad att en del avIf places indeed matter, as economic geographers believe, then it must matter most to the people who live their everyday lives in these places and experience the world materially and socially through it. When a crisis hits and uncertainty ensues, it affects people who call these places home the most. So much so, that some of them might be willing to stake a claim on its recovery, and development
Introduction: Obesity continues to be a growing problem and places a significant burden on the healthcare system by increasing the risk of developing various diseases including type 2 diabetes (T2D). T2D, in turn, increases the risk of developing other diseases, such as cardiovascular diseases (CVDs), neuropathy, and nephropathy. Furthermore, obesity and T2D are closely linked to liver diseases, p
This invention comprises, on one hand, a method of detecting and quantifying components separated by capillary electrophoresis or other technique using thin capillaries in the separation, and on the other hand, an apparatus for performing this detection. The method comprises irradiating the whole or large parts of the capillary at short time intervals and detecting the fluorescence originating fro
The present invention relates to a method for detecting particles and a particle sensor arrangement. More specifically, the present invention relates to a method and arrangement for detecting particles in a gas flow, e.g. from a diesel combustion engine. The method comprises the steps of; forcing a ... ...
Assessment of robustness of structural systems very often involves assessment of the structural response after local damage. In this paper an attempt is made to describe the state of art in this field with focus on methods which can be used in engineering practice. Advanced non-linear and dynamic computer tools are available today which can deal with most of the above mentioned phenomena but they
Proton exchange membrane fuel cells (PEMFCs) are expected to play a significant role in the next generation of energy systems and road vehicles for transportation. To achieve high performance, low cost and high reliability, significant attention is needed on detailed modeling and simulation of various physical processes in PEMFC unit-cells. Substantial effort is also required to reach proper water
We investigate the use of particle filter (PF) estimation techniques on a hovercraft vehicle in an office environment. Monte Carlo Localization (MCL) with particle filtering is a popular method for localizing robots with laser range finders. In maps featuring long, uniform corridors though, a PF can produce low confidence estimates. When used as feedback to control an unstable vehicle this can pro
In medical research and within the field of Biology, it is important to find effective tools for probing and manipulating cells, as well as tools for detecting biomolecules. These tools should be sensitive, with high specitivity, and, if aimed at interacting with cells, they should be minimally invasive. In this thesis, I investigated the potential of various nanotools for these purposes. Specific
