Phase shifter-based hybrid beamforming has received a lot of attention at millimeter-wave frequencies for cellular communications. Nevertheless, the implementation complexity of such beamformers is rather high due to the complexities involved in designing and fabricating the required radio-frequency (RF) circuits. In contrast, lens-based RF beamformers significantly reduce the implementation compl
Studies conducted in historical populations and developing countries have evidenced the existence of clustering in infant deaths, which could be related to genetic inheritance and/or to social and cultural factors such as education, socioeconomic status or parental care. A transmission of death clustering has also been found across generations. One way of expanding the knowledge on intergeneration
Big Data Applications (BDAs) manage so much data to require a cluster of machines for computation and storage. Their execution often has temporal constraints, such as deadlines to process the data. BDAs are executed within Big Data Frameworks (BDFs), that provide mechanisms to automatically manage the complexity of the computation distribution. For a BDA to fulfill its deadline when executed in a
The power exponent α in the temperature dependence of laminar burning velocity [Formula presented]=[Formula presented]α is usually considered an empirical parameter extracted from measurements performed at different temperatures. In this paper an analytical derivation of α is proposed, calculating the power exponent from the overall activation energy as: αTu 0→Tu
BACKGROUND: To investigate the outcome of an integrated individual and family therapy (Intensive Contextual Treatment: ICT) in terms of reducing suffering and increasing functional adjustment among self-harming and/or suicidal adolescents with high symptom loads and their families. METHODS: Forty-nine self-harming and/or suicidal adolescents, Mage = 14.6, of predominantly Swedish origin and female
Research on air travellers’ willingness to pay (WTP) for climate change mitigation has focussed on voluntary emissions offsetting so far. This approach overlooks policy relevant knowledge as it does not consider that people may value public goods higher if they are certain that others also contribute. To account for potential differences, this study investigates Swedish adults’ WTP for a mandatory
The dynamics of ethanol production/consumption in baker's yeast were studied under feed- rate controlled conditions. The yeast was grown on molasses in an 8-l fed-batch reactor and experiments were done at cell concentrations between 5 and 65 g l−1. Small changes in the feed rate were made around a feed rate corresponding to the critical growth rate, at which the yeast cell metabolism switches bet
In this paper some of the numerical problems associated with computing the generalized inverse of a matrix are discussed and illustrated by a detailed analysis of an iteration of Ben-Israel and Cohen.
Aim: This study investigates how often bowel continuity was restored after anastomotic leakage in anterior resection for rectal cancer and assesses the clinical factors associated with permanent stoma. Method: The Swedish Colorectal Cancer Registry was used to identify cases of anastomotic leakage registered in southern Sweden between January 2001 and December 2011. Patient characteristics, surgic
The ever-increasing consumption of natural resources required for the production of consumer electronics, and the growing amount of electronic waste, underline the importance and urgency of extending the lifespan and use of such products. Information and Communication Technology (ICT) remanufacturing is a growing industry, which nonetheless faces several barriers. Consumers often have a perception
Detta kapitel analyserar vad man kan kalla automatiserad policyimplementering på digitala plattformar och därmed kombinationen av normativitet och plattformisering. I kapitlet fokuseras betydelsen av de automatiserade verktyg där varianter av artificiell intelligens och maskininlärning används för att moderera och effektivisera olika informationsflöden. Här tecknas tre kategorier där plattformar a
Denna rapport ger en översikt av linjär optimal stokastisk kontroll. De fundamentala problemen formuleras och de centrala resultaten gives, utan bevis men med utförliga fysikaliska tolkningar. Användandet av siffermaskiner både för syntes och implementering behandlas. Vidare diskuteras några praktiska problem förenade med det optimala systemets realisering: val av samplingstid, reelltidsberäkning
The TRE3 research project focuses on the development of a new and innovative timber frame wall modulus for emergency housing facilities. The wall modulus, in this paper referred to as Hybrid Timber Frame (HTF) wall system, is an evolution of the traditional Light-Frame Timber (LFT) structural systems and combines the advantages and some peculiar aspects of lightweight structures to the potentialit
