Let V be an n-set, and let X be a random variable taking values in the power-set of V . Suppose we are given a sequence of random coupons X1 , X2 , ..., where the Xi are independent random variables with distribution given by X. The covering time T is the smallest integer t ≥ 0 such that the union of the first t Xi's equal V . The distribution of T is important in many applications in combinatoria

A controller for critical vehicle maneuvering is proposed that avoids obstacles and keeps the vehicle on the road while achieving heavy braking. It operates at the limit of friction and is structured in two main steps: a motion-planning step based on receding-horizon planning to obtain acceleration-vector references, and a low-level controller for following these acceleration references and transf

BACKGROUND: Intraabdominal and retroperitoneal sarcomas (IaRS) are malignant connective tissue tumors. Surgical resection is often the only curative treatment. The primary objective was to report the mid-term outcomes following contemporary treatment protocols and identify prognostic factors.METHODS: A retrospective review of consecutive patients (n = 107) with IaRS treated at single center from 2

Soil microbiome is one of the most heterogeneous biological systems. State-of-the-art molecular approaches such as those based on single-amplified genomes (SAGs) and metagenome assembled-genomes (MAGs) are now improving our capacity for disentailing soil microbial-mediated processes. Here we analyzed publicly available datasets of soil microbial genomes and MAG's reconstructed from the Amazon's tr

Low energy buildings are usually characterized by a very well insulated building envelope and an efficient ventilation system that makes use of the heat in the exhaust air. Internal heat gains from residents and their use of appliances can cover the heating demand to a certain extent. The magnitude of internal heat gains that cover demand are often modelled in a simplified way and thus can be asso

Understanding the etiology and meaning of behavioral symptomatology in the context of neurologic disease, and choosing the most effective intervention is a vexing task. This introduction summarizes the history of our understanding of the relationship between behavioral symptoms and primary neurologic conditions, and considers the ways in which both psychiatric and neurologic disorders occurring si

Lignin is the second most abundant naturally produced organic polymer on earth. Lignin‐modifying enzymes (LMEs) are produced by the white‐rot fungi as products of secondary metabolism, since lignin degradation does not provide any energy to the fungus. The main oxidative enzymes include the peroxidases‐lignin peroxidase (LiP) (diarylpropane: oxygen, hydrogen peroxide oxidoreductase), manganese per

With platelet activation, there is modulation of platelet surface molecule expression. In flow cytometric analyses of in vivo platelet activation, results are often confounded by activation induced in vitro by the preparative procedures. It is particularly important therefore to prevent or retard platelet activation as soon as possible after withdrawal of the blood sample. Taking blood into parafo

This paper presents the design and features of frequency-selective wallpaper-based on periodic and symmetric metallic hexagons-intended to be attached to standard walls for filtering out 5GHz signals (e.g., IEEE 802.11a systems)without blocking other selected radio communication services (e.g., cellular mobile communication signals). It analyzes the characteristics of the radio channel-as found wi

Sweden has the highest rate of single households in the world (2012) as nearly half of the population live by themselves. Even though many Swedes live alone research suggests that dinner party trends (social cooking) will increase - a simple activity, regarding both cost and accessibility, that brings us together with friends and family in our single household life style. I am addressing the scena

Det är svårt att stifta en konkurrenslag som effektivt motverkar karteller samtidigt som den tar tillvara företagens rätt till en rättvis rättegång. Vårt samhälle är idag präglat av en marknadsekonomi som är i behov av en välfungerande konkurrens. Karteller är kostsamma för samhället och ytterst för samhällsmedborgarna. Det finns betydande incitament för företag att samarbeta konkurrensbegränsande

The building industry, like many others, are currently experiencing the effects of the digitalization, and the increased spread of smart buildings is a result of this. Much research has been done on smart buildings and their predecessors intelligent buildings, but there is limited research available on how entrance systems should be designed for smart buildings, especially regarding their connecte

Upplevelsen av Malmö är för mig, och för många andra som inte vuxit upp i staden, en ganska grå stad. Kvarter efter kvarter med tegelhus som före detta arbetarbostäder för de stora industrierna. Stadens bild har ändrats mycket under senare tid och efter att ha bott i staden i några år har jag också fått en mer nyanserad bild av hur många olika ansikten staden har - nya platser, hus och miljöer dykThe image of Malmö is to me, and others that hasn’t grown up in the city, a fairly grey story. Blocks after blocks of brick buildings housing the former workers of the great industries that once were the pillars of the city. The face of the city has changed quite radically in recent years and my personal image of the city has been diversified with new places, buildings and environments, which cons

Inom matematiken är det ofta intressant att studera olika strukturer, deras egenskaper, och hur man bäst representerar dem. Så kallade ideal av ringar är ett välstuderat område, men en liknande klass av strukturer kallad subalgebror är hittills mindre studerade. I denna text ges grundläggande definitioner och satser relaterat till LAGBI baser som sedan används för att klassificera vissa polynomsubIn this text, we study almost monomial subalgebras using LAGBI bases. We introduce the concept of a LAGBI base and present an algorithm for computing them. We then use this algorithm to find, and present in a table, all polynomial subalgebras with Frobenius number smaller than or equal to ten. We then prove that some patterns observed in this table hold. Lastly we give a proof of what properties i

Den globala uppvärmningen förändrar jordens klimat i snabb takt, det är främst utsläpp av växthusgaser som exempelvis koldioxid från förbränning av fossila bränslen som är orsaken. Sverige har tagit flera steg mot en hållbar energiproduktion där 65 % av elen är förnybar, men samtidigt är fossila bränslen en betydande del. Av Sveriges totala energianvändning går 25 % till att värma upp det befintliGlobal warming is changing the Earth's climate and is mainly caused by greenhouse gas emissions from, for example, fossil fuels. Sweden's energy production consists of 65 % renewable energy, but the remaining amount comes from fossil fuels. Of Sweden's total energy production, a quarter goes to heating existing buildings. Upcoming EU directives set higher requirements for energy effici

The rise in entrepreneurial activity over the last 15 years has created space for a nascent industry among the public and private sectors: Business Support Organization (BSO). In the last years, some BSOs have broadened their offer to include for-profit social ventures. Unlike traditional businesses, these ventures try to create a positive social impact while attempting to be economically self-sus
