This paper presents an evaluation of single input single output (SISO), single input multiple output (SIMO) and multiple input multiple output (MIMO) channel capacities for a dual antenna prototype in proximity of a user. The dual antenna prototype mimics today’s small mobile phone design in size and in comprising internal, compact, multi-band antennas. Four different user cases are evaluated by m
Finding the optimal subset of individuals to observe in order to obtain the best estimate of the average opinion of a society is a crucial problem in a wide range of applications, including policy-making, strategic business decisions, and the analysis of sociological trends. We consider the opinion vector X to be updated according to a DeGroot opinion dynamical model with stubborn agents, subject
Reference attribute grammars (RAGs) have reached a level of maturity where they are supported by several tools, and have gained traction in both academic and industrial language tool development. However, despite a lot of accumulated knowledge of how to best develop RAGs in practice, there is limited support to guide practitioners.In this paper, we address this issue by focusing on one RAG tool, J
In this paper we study the convex envelopes of a new class of functions. Using this approach, we are able to unify two important classes of regularizers from unbiased non-convex formulations and weighted nuclear norm penalties. This opens up for possibilities of combining the best of both worlds, and to leverage each method’s contribution to cases where simply enforcing one of the regularizers are

Treatment of met-myoglobin (Fe-III) with H2O2 gives rise to ferryl myoglobin, which is closely related to compound II in peroxidases. Experimental studies have given conflicting results for this species. In particular, crystallographic and extended x-ray absorption fine-structure data have shown either a short (similar to170 pm) or a longer (similar to190 pm) Fe-O bond, indicating either a double
Global solar radiation (GSR) prediction capability with a reliable model and high accuracy is crucial for comprehending hydrological and meteorological systems. It is vital for the production of renewable and clean energy. This research aims to evaluate the performance of combined variational mode decomposition (VMD) with a multi-functional recurrent fuzzy neural network (MFRFNN) and quantile regr
Varje år sker det tusentals olyckor i trafiken i Sverige till följd av det stora transportbehovet i samhället. Transportstyrelsen har ett mål, Nollvisionen, som innebär att ingen ska dödas eller skadas allvarligt i trafiken. För att nå målet är en åtgärd att hastigheten sänks där gång- och cykeltrafik behöver interagera med motorfordon. Det kan man göra i form av sidoförskjutningar, avsmalning av Every year, thousands of traffic accidents occur in Sweden as a result of the transportation need in society. The Swedish Transport Agency has a goal, Vision Zero, which means that no one should die or be severely injured in traffic. To reach the goal one measure is to reduce the speed where pedestrians and cyclists need to interact with motor vehicles. This can be done by chicanes, narrowing of t
Våra forskare möter samhällets utmaningar inom IT och kommunikation. Tillsammans med industrin bygger de framtidens informationsteknologi genom nya innovationer, metoder och kunskap. Utvecklingen av och efterfrågan på 6G-teknik, robotar och självkörande bilar går snabbt framåt. Inom dessa snabbt föränderliga områden är teknologiska genombrott helt avgörande för att vi ska kunna möta industrins beh

The Water hyacinth is one of the worst aquatic weeds in the world and it is today present on all continents except Antarctica. It causes big problems for both people and the aquatic ecosystems in many countries. A lot of research has been completed to find methods to eradicate the weed and a lot of money has been spent on management to keep waters clean. In this literature study on management meth
Ett interaktivt digitalt system för att kontrollera blodtrycket gör att fler får ett kontrollerat blodtryck. Det visar distriktsläkaren Ulrika Andersson i sin avhandling vid Lunds universitet. Drygt 900 patienter vid 31 vårdcentraler i södra Sverige har deltagit i studien. Samtliga var redan patienter och behandlades för högt blodtryck. Högt blodtryck är en folksjukdom som ungefär varannan person

High-quality video is being increasingly delivered over Internet Protocol networks, which means that network operators and service providers need methods to measure the quality of experience (QoE) of the video services. In this paper, we propose a method to speed up the development of no-reference bitstream objective metrics for estimating QoE. This method uses full-reference objective metrics, wh
Problem statement This master thesis was initiated since today, when developing a new mobile phone at Sony Ericsson, it is difficult to get a perception of the ergonomics and the tactility of the keyboard before the first design prototype (DP0 and DP1) is built. The SLA block model used today is completely solid and consequently a secured decision of the final design can not be made in this phase
Artificial intelligence powers everything from facial recognition to self-driving cars, but what does it really take to teach a computer to “see”? Isak Engdahl, who recently defended his doctoral thesis at Lund University, takes us inside the labs where computer vision systems are built, and reveals the human work behind the technology. On Friday 28 November, Isak Engdahl successfully defended his

This article is over 5 years old, and the information may therefore be outdated. The earth is both inundated and drying up. Water supply is a complex phenomenon that has probably never been more complicated – or more important – than now. Kenneth M.
