The Laws' Properties

We are good at discussing law statements of different epistemic status, and to describe logical relationships between different law statements. But contemporary discussion often suffers from a difficulty to formulate questions concerning laws of different ontological status. This paper presents a framework for distinguishing between properties and fake properties that seems to provide better tools

Optimal graph exploration without good maps

A robot has to visit all nodes and traverse all edges of an unknown undirected connected graph, using as few edge traversals as possible. The quality of an exploration algorithm A is measured by comparing its cost (number of edge traversals) to that of the optimal algorithm having full knowledge of the graph. The ratio between these costs, maximized over all starting nodes in the graph and over al

Designing societal safety: A study of the Swedish crisis management system

Design is an activity aimed at solving an unsolved problem or improving an existing solution. In the area of societal safety, there are many activities that could be classified as design activities. For example when different actors are implementing measures to mitigate certain risk scenarios or when they are considering actions that could improve their capability to respond to various crises. We

A VLSI architecture of the Schnorr-Euchner decoder for MIMO systems

The lattice decoder is shown to approach the performance of Maximum-likelihood decoder for MIMO wireless systems with low complexity. A VLSI architecture of the K-best Schnorr-Euchner lattice decoder is proposed in this paper. The architecture is optimized on both algorithm and architecture levels, and supports a dynamic range of SNR [less-than or equal to] 30 dB. Compared to a conventional VLSI i

Victims of human trafficking in the asylum procedure. A legal analysis of the guarantees for 'vulnerable persons' under the second generation of EU asylum legislation

Victims of human trafficking have been designated as a group of migrants in need of special assistance and protection. As a result, a whole legal framework has been developed revolving around this group. Within Europe, this framework operates on two levels: the Council of Europe and the EU. EU law has added an additional layer of sophistication with its second generation of asylum legislation. The

Studies towards late blight control in potato

Popular Abstract in English Plant diseases are directly associated with food security because they result in severe reduction of plant yield and thus they add to the scarcity of foods in the world, which can lead to negative repercussions on humankind. Late blight disease that severely hit Ireland in 1840s, which was caused by Phytophthora infestans and is mentioned in the historical records as thAbstract The oomycete Phytophthora infestans, which causes the devastating late blight disease of potato, is notorious for developing resistance to conventional control strategies (fungicide application and resistance breeding by introgression of R gene). To increase our tool box of disease management strategies available to combat P. infestans, there is a need to explore several new approaches th

A Physical Two-Zone NOx Model Intended for Embedded Implementation

This paper offers a two-zone NOx model suitable for vehicle on-board, on-line implementation. Similar NOx modeling attempts have previously been undertaken. The hereby suggested method does however offer clear and important benefits over the previously methods, utilizing a significantly different method to handle temperature calculations within the (two) different zones avoiding iterative computat

Inference and management of populations in variable environments

Popular Abstract in Swedish En central frågeställning inom ekologin handlar om hur och varför organismers utbredning och antal varierar i tid och rum. Detta forskningsfält går under namnet populationsdynamik och är ämnet för min avhandling. Populationsdynamik handlar om mönster, slumpmässighet, förändringar; helt enkelt matematik! Av den anledningen är det inte bara önskvärt, utan faktiskt nödvändPopulation dynamics in space and time are manifested as changes in the distribution and abundance of organisms. To couple such patterns to the underlying processes is a central question in ecology and also key to successful management. In this thesis, I use theoretical models as well as time series data to analyze population dynamics in environments that are variable in space or time. An example o

Reduced Search Space for Rapid Bicycle Detection

This paper describes a solution to the application of rapid detection of bicycles in low resolution video. In particular, the application addressed is from video recorded in a live environment. The future aim from the results in this paper is to investigate a full year of video data. Hence, processing speed is of great concern. The proposed solution involves the use of an object detector and a sea

Rank-One Convexification Approach for the Modeling of Magnetic Shape Memory Response

We present an incremental energy minimization model for magnetic shape memory alloys (MSMAs) whose derivation departs from the constrained theory of magnetoelasticity [1], but additionally accounts for elastic deformations, magnetization rotation, and dissipative mechanisms. The minimization of the proposed incremental energy yields the evolution of the internal state variables. In this sense, the

Conditions for creativity in different contexts

The concept of creativity will be discussed, outgoing foremost from the process oriented theoretical framework named the perceptgenetic (PG) model, first developed in the 50ies, and from that time empirically validated and applied in Lund University and elsewhere. Within the PG model numerous research questions have been operationalized and tested over the years, often with an underlying psychodyn

Exploring the microbiota of the gastrointestinal tract

Popular Abstract in English Like earth is home for us, our gastrointestinal (GI) tract is home for microbes. All the bacteria that are living there are called “microbiota” and the total DNA they contain is called “microbiome”. The GI microbiota outnumbers human cells by factor of ten and the microbiome is at least 100 times larger than our human genome. A wide range of metabolic activities are perAbstract: Balanced microbiota of the gastrointestinal (GI) tract is important for maintaining health of the host. Altered gut microbiota have been found to be associated with various life-style induced and other intestinal inflammatory diseases. Gut microbiota is viewed as a metabolic organ and considered as new target for therapies. This thesis describes the work on exploring the microbiota of th
