This report aims at finding methods for reducing the errors in district heating load forecasts by suggesting a method for online correction of the base forecast. Online correction is generally carried out by utilizing patterns in the historic prediction errors. Traditionally the correction has been made using a correction method detailed by a few governing parameters. Values for these parameters a

The thesis aims to explore what influences the Danish consumers when choosing food distribution channels in 2020 and further to test if current theories of consumers’ channel choice can be applied in the year of 2020. The thesis takes on a qualitative approach with mathematical principles and employs the Delphi Method as the primary method to collect data. To conduct the empirical analysis a desk

This chapter examines if identity is as important as is often claimed, and as a consequence, when and why concerns of identity are triggered in working life, and we do so through a constructionist identity perspective. In the chapter, we argue that many people do not necessarily engage with their identities most of the time and explore why they do in certain kinds of jobs and in particular situati

A user-friendly high-resolution intermediate complexity dynamic and spatially distributed flow model is crucial in urban flood modeling. Planners and consultants need to improve the accuracy of floods and estimation of risks. A new flow model will serve as a rapid tool to improve identification of these. This article provides a detailed explanation of a model based on a multiple flow algorithm.

Popular Abstract in Swedish Graviditetsdiabetes (GDM) definieras som nedsatt glukostolerans av varierande svårighets¬grad som upptäcks under graviditet och som oftast försvinner efter förlossning. GDM innebär ökad risk för såväl moder som barn. Kvinnor med GDM föder ofta stora barn och har ökad risk för komplikationer i samband med förlossningen. GDM-prevalensen varierar avsevärt mellan olika popuGestational diabetes mellitus (GDM) is a heterogeneous disorder that is defined as carbohydrate intolerance with onset or first recognition during pregnancy. Impaired beta-cell function and insulin resistance are the hallmarks of GDM. The overall aim of this thesis was to study the genetic and immunological risk factors that increase susceptibility to GDM. First, we investigated whether autoimmuni

Popular Abstract in Swedish Avhandlingen handlar om islamisk predikokonst i teori och praktik, med särskilt fokus på islamisk predikan inspelad och publicerad på ljudkassett. Huvudmaterialet består av fyra kassetter med inspelningar av predikningar på arabiska: 1) Ismail Hamidi, ”Underrättelsen om uppståndelsens dag”; 2) Ahmad al-Qattan, ”Vägen till Paradiset/Lustgården”; 3) Ahmad al-Qattan, ”BeräThe dissertation deals with Islamic preaching in theory and practice, with special focus on material recorded and published in the format of audiotapes/cassettes. One aim is to explore possible implications of the use of this special format of publication in the context of Islamic preaching. How is this new format of publication to be understood in relation to the norms regulating the activity of

Sorption isotherms describe the relation between the equilibrium moisture content of a material and the ambient relative humidity. Most materials exhibits sorption hysteresis, that is, desorption give higher equilibrium moisture contents than absorption at equal ambient climate conditions. Sorption hysteresis is commonly evaluated by determination of an absorption isotherm followed by desorption sSorption isotherms describe the relation between the equilibrium moisture content of a material and the ambient relative humidity.

The ratio of the electric and magnetic form factors of the proton G(Ep)/G(Mp), which is an image of its charge and magnetization distributions, was measured at the Thomas Jefferson National Accelerator Facility (JLab) using the recoil polarization technique. The ratio of the form factors is directly proportional to the ratio of the transverse to longitudinal components of the polarization of the r

Smoking is a leading cause of preventable death, causing about 5 million premature deaths worldwide each year(1,2). Evidence for genetic influence on smoking behaviour and nicotine dependence (ND)(3-8) has prompted a search for susceptibility genes. Furthermore, assessing the impact of sequence variants on smoking-related diseases is important to public health(9,10). Smoking is the major risk fact

Cutting-edge technology needs small, ultrafast devices, operational in a wide range of regimes. This calls for solids with novel, unconventional and tailorable properties. Great progress is expected from materials in which electron-electron and electron-phonon correlations strongly affect the dynamics ( i.e. "unforeseen" useful properties are expected to be most likely found in systems with comple

Popular Abstract in Swedish Aerob kapacitet, i dagligt tal konditionen, är den maximala förmågan att utföra ett fysiskt arbete karaktäriserat av den maximala syreförbrukningen (V'O2max). Detta maximala arbete kan endast utföras en begränsad tid, till stor del beroende på en tilltagande anaerob metabolism, vilken bl.a. avspeglas som en ökning av utvädrat CO2 i lungorna. Längre tids arbete kan emellDifferent methods are proposed to assess the aerobic capacity. A novel scale, rating of perceived capacity (RPC) based on metabolic equivalents (METs) from 1 to 20, is presented. Selected MET values are linked to physical activities. Comparison of the rating with an exercise test in a group of women revealed that a correction based on age more accurately predicted the maximal exercise capacity. An

Polymorphisms in genes that encode for metabolic enzymes have been associated with variations in enzyme activity between individuals. Such variations could be associated with differences in individual exposure to carcinogens that are metabolized by these genes. In this study, we examine the association between polymorphisms in several metabolic genes and the consumption of tobacco in a large sampl

A first lesson in physical chemistry invariably starts with an example of water existing in three states, or phases - gaseous (water vapour), liquid (water from the tap) and solid (ice cubes). Such phase transitions are easily observed, but their underlying cause is not so evident. Atoms and molecules are difficult to follow due to their minute size and rapid movements. So, in order to investigateThe effect of microscopic colloid interactions on the resultant macroscopic phase behaviour is a frequently studied topic in soft matter resarch, and lies at the heart of this thesis. Key structural and dynamic properties of colloidal model systems across liquid-solid transitions are tracked using optical imaging techniques. The first studied system comprises of thermosensitive microgels. These ar

It has previously been shown that the cerebellum is critical for classical conditioning. The experiments presented in this thesis aimed to study how the cerebellum controls conditioned eyeblink responses (CRs) and specifically the efferent path from the cerebellar cortex to the muscles. Ferrets, decerebrated rostral to the superior colliculus and the red nucleus, were trained in a classical condit

Digitalisering av ekonomin och nya digitala affärsmodeller har skapat utmaningar för det internationella skattesystemet. Organisationen för ekonomiskt samarbete och utveckling, OECD, har under de senaste åren arbetat med att ta fram förslag som kan hantera problematiken. Beskattningen av ett företag sker baserat på i vilken stat som företaget har hemvist. Enligt den nuvarande regleringen av fast dThe digitalisation of the economy has resulted in new business models that pose substantial tax challenges for the international tax system. The Organisation for Economic Co-operation and Development, OECD, has published various reports and proposals on how to address these challenges. Under the current system enterprises are taxed based on residency. However, another state may tax an enterprise i

Value chains have been an established concept in economics and business since 1985 when it was coined by Professor Michael E. Porter. Porter used value chains to explain value creating activities within companies where each activity is an important link in a larger chain which generates value and competitive advantages for companies. By overviewing its value chain, each company can streamline and

One of the characteristic features of Indian society is its complex caste system which ranks people into hereditary groups. Most importantly, the foundation of caste association was based on the occupation of each group. And the lowest group within this system have historically been excluded and exploited due to their assigned caste-based occupations. Despite implementing affirmative action polici
