This thesis examines how active power control (Volt-Watt control) and reactive power compensation (Volt-VAr control) can help limit voltage increases on the low voltage grid due to high photovoltaic (PV), installations. Due to the large increase in interest to install small scale PV-systems within residential areas the Distribution System Operator E.ON, has noticed problems concerning high voltage

Syftet med mitt examensarbete är att undersöka i detalj hur gällande folkrätt förhåller sig till autonoma vapensystem. Bakgrunden till detta projekt är att internationell humanitär rätt förutsätter att aktörerna i kriget, soldater och officerare är människor. Krigföring har dock förändrats i allt högre grad sedan de första Genèvekonventionerna skrevs i augusti 1949. Krig kämpas numera med maskinerThe purpose of my Master Thesis is to examine, in detail, how current international law relates to autonomous weapon systems. The background for this project is that the requirement of current international humanitarian law presupposes that the characters of war, namely soldiers and military officers, are human beings. Warfare has, however, changed increasingly since the Geneva Conventions were wr
This Master thesis work was performed in Ericsson AB, Lund. It studies and validates two classes of algorithms to be used in mm-wave massive MIMO antenna arrays, for their use in the future 5G mobile communication systems. The first class of algorithms relates to the calibration of the transceiver (TRX) chains responses of the antenna array and makes use of the antenna array mutual coupling, which
Do Russian Melitaea butterflies contain the symbiotic bacteria Wolbachia? Background Up to 60 percent of insect species in the world are infected with the intracellular, obligate symbiont called Wolbachia pipientis, making it one of the most common arthropod endosymbionts, and potentially one of the most successful organisms on Earth. The bacterium affects its host species in negative and/or posi
1 januari 2018 infördes brottet olaga integritetsintrång i brottsbalkens fjärde kapitel. Lagstiftningen var ett resultat av ett större arbete med syfte att skydda enskildas personliga integritet. Olaga integritetsintrång blir tillämpligt när någon olovligen sprider integritetskränkande bilder, däribland sexuella bilder. Spridning av dessa bilder på internet har under senare år varit ett växande prOn January 1, 2018, unlawful intrusion of integrity was added to the fourth chapter of the Swedish Penal Code. The legislation was part of a larger agenda from the Swedish government designed to protect the people’s personal integrity. Unlawful intrusion of integrity is applicable when someone is illegally distributing intrusive images, among them sexual images. The distribution of these images on
I juli 2023 tillsatte regeringen en utredning i syfte att genomföra en övergri- pande översyn av straffskalorna samt lägga fram förslag till ett reformerat och mer rättvist påföljdssystem. Regeringen framhåller i direktivet att straffsyste- met bör uttrycka en tydligare klandervärdering av brottsliga gärningar för att undvika att brottsoffer upplever rättsprocessen som ytterligare en kränkning. DeIn July 2023, the Swedish government appointed an inquiry with the purpose of conducting a comprehensive review of the penalty scales and presenting proposals for a reformed and fairer penalty system. The government empha- sizes in the directive that the penal system should express a clearer condem- nation of the blameworthiness of criminal acts in order to avoid that victims experience the legal
Today there are close to 90 objects of interest in Sweden who are considered a threat to the environment and people’s health. These objects are in the process of being decontaminated within a near future. All together there are 80 000 objects identified and 17 000 of them has been risk classified. According to the Swedish environmental goal “Poison free environment” the most important actions are

Popular Abstract in Swedish Bakgrund Streptococcus pyogenes, eller grupp A streptokocker, är en av de vanligaste sjukdomsframkallande bakterierna hos människan. De orsakar ofta relativt harmlösa och lättbehandlade ytliga infektioner i hals (halsfluss) och hud (svinkoppor) men kan också ge djupare och livshotande infektioner. Dessutom förekommer följdsjukdomar efter infektioner med grupp A streptoPathogenic bacteria often produce potent proteases capable of destroying host tissue thereby providing the bacteria with tools for spreading and nutrient access. This thesis describes how group A, C and G streptococci can acquire surface bound protease activity through an alternative mechanism, namely by binding and activation of the human protease precursor plasminogen. Group A streptococci of c
Popular Abstract in Swedish I avhandlingen "Dynamisk dialog: en analytisk och konstruktiv studie av den religiösa kommunikationens problem på grundval av Martin Bubers dialogfilosofi" studerar jag olika aspekter av Bubers modell för hur en människa meningsfullt kan kommunicera sin religiösa upplevelse till och med en annan människa. Min metod har både en begreppsanalytisk och en fenomenologisk sidIn the present work, I study various aspects of Martin Buber's model of how a human being can communicate, in a meaningful way, his or her religious experiences to and with another human being. My method has aspects of both conceptual analysis and phenomenologial description. I focus on the individual partners, their mutual relationships and the religious message. Buber's model is based on the con
This thesis is an empirical and theoretical exploration of the surprising finding that people often may fail to notice dramatic mismatches between what they want and what they get, a phenomenon my collaborators and I have named choice blindness. The thesis consists of four co-authored papers, dealing with different aspects of the phenomenon. Paper one presents an initial set of studies using a co
BACKGROUND The efficacy and effectiveness of the quadrivalent human papillomavirus (HPV) vaccine in preventing high-grade cervical lesions have been shown. However, data to inform the relationship between quadrivalent HPV vaccination and the subsequent risk of invasive cervical cancer are lacking. METHODS We used nationwide Swedish demographic and health registers to follow an open population of 1
Concepts are the basic building blocks of all knowledge, while the strength of the theories that guide any societal project is dependent on the quality those concepts. Contrarily, the utilization of questionable concepts will result in questionable material effects. As two of the oldest geographical concepts still in widespread use, ‘rural’ and ‘urban’ stand in stark contrast to the immense change
BACKGROUND: Permanent pacemaker implantation (PPM) early after cardiac transplantation has been shown not to predict a worse outcome. However, the requirement for pacing late after transplantation and its prognostic implications are not fully known. We describe the clinical indications, risk factors and long-term outcome in patients who required pacing early and late after transplantation.METHODS:
This paper performs a numerical study regarding the effects of different kinds of coolants on flow and heat transfer in a pin-finned internal channel. A new pin-fin structure detached from one endwall with a round-tip is proposed which aims to increase the heat transfer enhancement. As a contrast, the investigation of the typical fully-attached pin-fin and the flat-tip detached pin-fin is also con
Aim: To add to our knowledge concerning the key elements involved in the individual’s experience of growing up with substance abusing parents and the resulting challenges this involved for their own parenthood. Methods: In-depth interviews were conducted with 19 parents who had participated in a mental health intervention programme. All had experienced substance abusing parents in their family of
A new approach to understanding the interaction between cortical areas is provided by a mathematical analysis of biased competition, which describes many interactions between cortical areas, including those involved in top-down attention. The analysis helps to elucidate the principles of operation of such cortical systems, and in particular the parameter values within which biased competition oper
Mitochondria are essential for early cardiac development and impaired regulation of mitochondrial function was implicated in congenital heart diseases. We described a newborn girl with hypertrophic cardiomyopathy and profound hearing loss. The mtDNA mutational analysis revealed the presence of known polymorphisms associated to cardiomyopathy and/or hearing loss, and 2 novel heteroplasmic mutations
