In this paper, we study fundamental performance limitations of distributed feedback control in large-scale networked dynamical systems. Specifically, we address the question of whether dynamic feedback controllers perform better than static (memoryless) ones when subject to locality constraints. We consider distributed linear consensus and vehicular formation control problems modeled over toric la
In quantum scattering processes between two particles, aspects characterizing the strong and Coulomb forces can be observed in kinematic distributions of the particle pairs. The sensitivity to the interaction potential reaches a maximum at low relative momentum and vanishing distance between the two particles. Ultrarelativistic heavy-ion collisions at the LHC provide an abundant source of many had
Efter att ha dominerat angloamerikansk filosofi under 1800-talets sista decennier kom idealismen att förlora sin ställning efter sekelskiftet, då övergången från viktorianska till modernistiska ideal, snabba sociala förändringar, ökad sekularisering och naturvetenskapens dominans tycktes kräva nytt filosofiskt tänkande. Vid andra världskrigets utbrott var idealismen utdöd och ersatt av den analytiAfter having dominated philosophical thought in Britain and the United States during the end of the nineteenth century, idealism was in steady decline by the outbreak of World War I. Its ideas and ideals seemed unsuited to face the transition from Victorianism to modernism and the rapid social changes of the post-war era. Its Anglo-American proponents—who were often liberals—were accused of indire
Pepsin-like aspartic proteases (PAPs) are a class of aspartic proteases which shares tremendous structural similarity with human pepsin. One of the key structural features of PAPs is the presence of a β-hairpin motif otherwise known as flap. The biological function of the PAPs is highly dependent on the conformational dynamics of the flap region. In apo PAPs, the conformational dynamics of the fla
Abstract Author: Therese Hovland and Sofia Stenberg Title: Mötesplats 0413 – An analyze of youths thoughts and opinions about their meeting place [translated title] Supervisor: Anders Östnäs Assessor: Carina Tigerwall Mötesplats 0413 is a culture house for youths at the ages of 16 to 25 years. The purpose of this study was, on the basis of a youth perspective, to critically analyze how the youth
Denna uppsats jämför de lagstiftningstekniker som valdes av Sverige respektive Storbritannien för att implementera den del av Postdirektivet som omfattar de samhällsomfattande posttjänsterna och vilka resultat respektive land har uppnått. Den utvärderar även EU:s val av regleringsmetod. Motivet bakom Postdirektivet, som trädde ikraft 1997, var EU:s vilja att försäkra invånarna tillgång till samhäThis essay compares the different ways that Sweden and Great Britain respectively chose to implement the part of the Postal Directive that include the universal services and the results that have been achieved by each country. It also evaluates the EU's choice of regulatory approach. The motive behind the Postal Directive, which came into force in 1997, was the EU's desire to assure resid
According to conventional economic wisdom, deregulation and liberalization of private and public enterprises will enhance competition, which will lead to an expansion of production, trade, and general welfare. As more markets are deregulated and more services are being privatized, the public procurement market is expanding and more professionals will come in contact with public procurement either
In the past decades there has been a progress in the legislation which regulates the rights of battered women. The social services are the authority which has the primary responsibility for battered women. This responsibility is regulated in the law since 1998. Evaluations have shown that the support for battered women needs to be improved since a majority of the rural districts don’t have any eme
Whether executed as full-scale war or acts short of war, acts of aggression have consistently shaped the history of humankind. Acts of aggression would not occur if it were not for the involvement of individuals. The historical development of aggression in international law has seen a shift from a regime solely focusing on the unlawfulness of the action by States, to include the unlawfulness of th
It is a commonly held belief that human rights and economic development has a relationship where the one hinders the other, and that governments in developing countries must choose one or the other. This essay explores the relationship between the two in the context of the economic development in South Korea since its liberation in 1948. It will do a historical overview and see how the economic po
The purpose of this study was to investigate the pupils´ perception of the school welfare officer’s professional role and availability. We also endeavored to find out to what extent the pupils express a need of a school welfare officer and whether a stigma is connected to the use of his/her consultation. We chose to conduct a quantitative survey at two different schools in the same municipality. T
The use of neutron protein crystallography (NPX) is expanding rapidly, with most structures determined in the last decade. This growth is stimulated by a number of developments, spanning from the building of new NPX beamlines to the availability of improved software for structure refinement. The main bottleneck preventing structural biologists from adding NPX to the suite of methods commonly used
Background: Paediatric surgical care is increasingly being centralized away from low-volume centres, and prehospital delay is considered a risk factor for more complicated appendicitis. The aim of this study was to determine the incidence of paediatric appendicitis in Sweden, and to assess whether distance to the hospital was a risk factor for complicated disease. Methods: A nationwide cohort stud
By providing supplemental food to Marsh Tits (Parus palustris) from the day the first egg was laid, effects on clutch size could be directly attributed to food without the confounding effects on laying date. Females provisioned with additional food responded by laying, on average, on egg more than control females. Differences in territory quality did not influence this result because, on territori
BACKGROUND: The dual-mobility acetabular cup (DMC) has an additional bearing consisting of a mobile polyethylene component between the prosthetic head and the outer metal shell. This design has gained popularity in revision total hip arthroplasty (THA) and in primary treatment of femoral neck fractures with the anticipation of a reduced risk of THA instability. Our primary aim was to evaluate the
BACKGROUND: Although growing evidence suggests that early-life excess manganese (Mn) impairs neurodevelopment, data on the neurodevelopmental effects of mancozeb, a fungicide containing Mn, and its main metabolite ethylenethiourea (ETU) are limited. OBJECTIVE: We examined whether prenatal mancozeb exposure and excess Mn were associated with neurodevelopment in 355 1-y-old infants living near banan
Ultrafast manipulations of magnetic phases are eliciting increasing attention from the scientific community because potentially relevant to the understanding of nonequilibrium phase transitions and to novel technologies. Here, we focus on manipulations applied to magnetic impurities in metallic hosts. By considering small nanoring geometries, we show how currents can induce a dynamical switching b
In this paper, I give a short description of a language change that can be viewedas an instance of grammaticalization, namely the transition of the two adjectivesmycken/t and liten/t into quantifiers. Data from the corpus of Swedish drama dialogue reveal that liten/t became a quantifier as early as the 1700s, whereas mycken/t seems to have gone through the same change roughly 150 years later. Inhe
