Feedback is a fundamental concept in automatic control. Feedback loops are used extensively in industrial applications today and there are work-procedures for designing traditional single parameter control loops. In the work procedure it is important to select control-parameters, manipulated parameters and control-strategies. A similar work-procedure could also be used for designing plant-wide con

We report our experience with surgery for femoral metastatic lesions, based on 216 patients who underwent a total of 245 operations for femoral metastatic lesions. The median age was 66 (30-94) years, and the most common diagnosis breast cancer, followed by prostate cancer. All patients had pain on weight bearing, 196 had pain at rest, 147 were unable to walk preoperatively, and 148 were confined

Open source computational fluid dynamics (CFD) codes provide suitable environments for implementation, testing and rapid dissemination of algorithms typically used for large-eddy simulations (LES) and direct numerical simulations (DNS). In particular, it is important to test low-dissipative algorithms in unstructured codes of industrial relevance. In the present paper, the implementation of incomp

To update the European League Against Rheumatism (EULAR) recommendations for vaccination in adult patients with autoimmune inflammatory rheumatic diseases (AIIRD) published in 2011. Four systematic literature reviews were performed regarding the incidence/prevalence of vaccine-preventable infections among patients with AIIRD; efficacy, immunogenicity and safety of vaccines; effect of anti-rheumati

Current large-scale deforestation poses a threat to ecosystems globally, and imposes substantial and prolonged changes on the hydrological and carbon cycles. The tropical forests of the Amazon and Indonesia are currently undergoing deforestation with catastrophic ecological consequences but widespread deforestation events have occurred several times in Earth's history and these provide lessons for

We show exponential lower bounds on resolution proof length for pigeonhole principle (PHP) formulas and perfect matching formulas over highly unbalanced, sparse expander graphs, thus answering the challenge to establish strong lower bounds in the regime between balanced constant-degree expanders as in [Ben-Sasson and Wigderson'01] and highly unbalanced, dense graphs as in [Raz'04] and [Razborov'03

We obtain the first true size-space trade-offs for the cutting planes proof system, where the upper bounds hold for size and total space for derivations with constantsize coefficients, and the lower bounds apply to length and formula space (i.e., number of inequalities in memory) even for derivations with exponentially large coefficients. These are also the first trade-offs to hold uniformly for r

Objective To compare the risk and severity of prostate cancer between men achieving fatherhood by assisted reproduction and men conceiving naturally.Design National register based cohort study.Setting Sweden from January 1994 to December 2014.Participants 1 181 490 children born alive in Sweden during 1994-2014 to the same number of fathers. Fathers were grouped according to fertility status by mo

Aim: To evaluate the long-term success rate of treatment with the Surgisis® (Biodesign®) anal fistula plug for complex anal fistulas, assess fistula plug failure over time and compare success rates for fistula plug between a group of patients with cryptoglandular fistula and another group with Crohn's fistula. Method: This is a single-centre study of consecutive patients treated with the Surgisis®

Artificial intelligence (AI) algorithms for automated classification of skin diseases are available to the con-sumer market. Studies of their diagnostic accuracy are rare. We assessed the diagnostic accuracy of an open-access AI application (Skin Image Search™) for recognition of skin diseases. Clinical images including tumours, infective and inflammatory skin diseases were collected at the Depart

Bakgrund Industri 4.0, den fjärde industriella revolutionen, handlar om att big data börjar utnyttjas inom tillverkningsindustrin. Detta öppnar upp helt nya möjligheter för tillverkningsföretag, men innebär också många risker och nya krav på företag. Syfte Syftet med det här projektet har varit att kartlägga hur ett företag bäst positionerar sig för att börja använda industri 4.0 och dessutom vilk

Vi rör oss ständigt i offentliga rum som på olika sätt är utformade för att påverka oss. Denna studie undersöker om människors känslor, syn på välbefinnande och syn på meningen med livet påverkas av att befinna sig i olika rum, i detta fall en kyrka (N=51) och ett köpcenter (N=51). Två verktyg, semantiska mått och Positive and Negative Affect Schedule (PANAS) används för att undersöka om det finnsWe are constantly moving between environments that are designed to affect us in one way or another. The purpose of this study is to investigate if the room has an influence on people's feelings, and their views on well-being and meaning of life. In a randomised experiment, the study explores whether there is a measurable difference in the participants’ feelings and thoughts in a church (n=51)

Syftet med studien är att undersöka hur kontrollmodellen har tolkats och tillämpats i praktiken inom fastighetsbranschen, utifrån de teoretiska perspektiven kring principbaserade standarder. Vidare ämnar studien analysera huruvida utfallet har bidragit till en mer jämförbar och konsekvent intäktsredovisning. Den forskningsstrategi som använts i denna studie är av kvalitativ karaktär. För att besva

In markets with fierce competition and low switching costs, the capability to keep customers is just as important as the capability to get new customers. One of the cornerstones of efficiently keeping customers from churning is the ability to identify customers that are more prone to leaving the company than others. This way, churn prevention resources and measures can be efficiently directed towa

Riksdagsdebatten om gängvåldet i Sverige har resulterat i ett förslag om en tillsatt utredning kring ett införande av möjligheten att vittna anonymt. Utredningen, som nu tas vidare av regeringen, är en av flera åtgärder som vidtas för att bryta tystnadskulturen inom organiserad brottslighet. Syftet med denna uppsats är att utreda om det finns tillräckliga skäl för en användning av anonyma vittneThe parliamentary debate on the gang violence in Sweden resulted in a proposal for an assigned investigation on the introducing of an opportunity to testify anonymously. The investigation, which is now led on by the government, is one of several measures taken in order to end the culture of silence in organized criminality. The purpose of this paper is to investigate if there are enough reasons f

In recent years the public's interest in beekeeping has increased. In relation to alarming news about pollinators declining globally, honeybees and beekeeping has been proposed as a part of the solution through their contribution to biodiversity and pollination. Alongside this idea there are critical voices that suggest that honeybees for different reasons has limitations as a part of the solu

Intresse- respektive skadekriteriet är beståndsdelar i två centrala principer vid kriminalisering. Deras funktion inom strafflagstiftningsarbetet är att verka begränsande, så att lagförslag som inte uppfyller kraven som de föreskriver, ej förverkligas. Den 14 juni 2018 beslutade regeringen att ge i uppdrag åt en särskild utredare att överväga ett straffrättsligt ansvar för uppmaning eller annan pThe criteria of interest and harm are components in two central principles in criminalization. Their function in criminal law is to act restrictively, so that legislative proposals that do not meet the requirements they prescribe are not enacted. On June 14, 2018, the Swedish government decided to commission a special investigation to consider criminal liability for incitement of, or other psycho
