Inom Europa beskriver begreppet energifattigdom de kompromisser som hushållkan möta avseende att å ena sidan ha en tillräckligt uppvärmd bostad, och å andrasidan ha råd med övriga omkostnader. I Sverige har begreppet tidigare inte använts, och kanske heller inte behövts. Men i december 2021 steg elpriserna till nivåer som gjorde att vissa hushåll, där en rad riskfaktorer sammanstrålade, plötsligt
Effekten av vindkraftens tillväxt är att vi i dag producerar mer el än vad vi behöver även då vi lagt ner flera kärnkraftverk. Klimatomställningen via elektrifiering pekar på ett fördubblat elbehov till 2045. Detta kräver mycket ny elproduktion. Och potentialen att bygga ut ny vindkraft är tillräcklig för att täcka behovet. Ny kärnkraft kan också bidra men kan tidigast vara i gång 2030 om inte sen

A detailed study of the structure of α-Cd13-xSb 10 was performed using a high quality single crystal obtained from a cadmiumrich melt. The study clearly shows that this sample is cadmium-deficient, and should more properly be labelled α-Cd13-xSb10, but whether this is true in general for this phase, or if it is an effect of the precise conditions of synthesis remains unclear. Like for the similar
While sensory perception is currently receiving quite a lot of attention across disciplines, little empirical research has focused on how people describe auditory experiences. Research on the representation of sound in fiction narratives has shown that sounds are frequently conceptualized as events whose descriptions are instantiated in domains other than sound proper, as in strong men banging the
Our research aims to develop an intelligent control system for optimizing the operation of lighting systems for a jogging track in the countryside by using adaptive control methods, and optimization of built-in lighting control. Through this, lighting systems will be optimized, energy consumption will be minimized and the lighting system will be adapted to be able to handle a larger amount of loca
I denna tvärvetenskapliga och internationellt förankrade forskningsmiljö undersöker vi å ena sidan hur rätten hanterar människor i utsatta positioner och å andra sidan hur de kan tillvarata sin rätt. Utgångspunkten är att möjligheten att tillvarata sin rätt kan förhindras eller försvåras om man befinner sig i en utsatt position, som barn, ungdom, gammal, sjuk, fattig eller hemlös. Konkret innebär We study how law treats people in vulnerable positions and how these people can make use of law. We are also interested in how the judicial system views individuals in relations to their context and to societal structures. The possibility to make use of one’s right can be obstructed or aggravated in a vulnerable situation, as a child or youth or old, disabled, poor or homeless person. Our research
This paper presents some of the results of the project, EXTOOL, Experience Curves: A Tool for Energy Policy Programmes Assessment, funded by the European Commission. The objective of the project was to analyse the experience curve as a tool for the assessment of energy policy measures. This is of special interest, since the use of experience curves for the assessment of energy policy measures requ
Antikens kultur och samhällsliv är ett periodstudium inriktat mot de äldre Medelhavskulturerna med tonvikt på den grekiska och romerska kulturen. Ämnet är mångvetenskapligt till sin karaktär och erbjuder olika ämnesmässiga och teoretiska ingångar. Grundläggande är att det omfattar både material- och textstudier, men perspektiven kan vara arkeologiska, historiska, konst- eller religionsvetenskapli
An integrated system for the production of hydrogen by gasification of biomass and electrolysis of water has been designed and cost estimated. The electrolyser provides part of the hydrogen product as well as the oxygen required for the oxygen blown gasifier. The production cost was estimated to 39 SEK/kg H-2 at an annual production rate of 15 000 ton, assuming 10% interest rate and an economic li
OBJECTIVES: Telehealth, the provision of healthcare through digital communication, has been proposed as a potential solution to meet the increasing demand for healthcare, particularly in the setting of the COVID-19 pandemic. Sweden has an established national telehealth service for triage and referral by phone (1177) since 2013 which has the potential to meet this increasing demand. However, littl
In order to improve the energy efficiency in district heating networks and the comfort of their customers, these networks need to overcome the problem of unfair heat distribution under heat deficits. This paper introduces a new strategy to achieve this thermal fairness objective: it is lowcost in terms of communication and computation. The proposed approach is illustrated on a simulation example.
Many computing systems are constrained by power budgets. While they could temporarily draw more power, doing so creates unsustainable temperatures and unwanted electricity consumption. Developing systems that operate within power budgets is a constrained optimization problem: configuring the components within the system to maximize performance while maintaining sustainable power consumption. This
Solid fuel fired fluidized bed (FB) boilers are common in combined heat and power (CHP) plants in district heating- and process industry. In this study, utilization of such FB boilers for production of syngas in dual fluidized bed gasifiers and subsequent catalytic biofuel production to substitute natural gas (SNG), methanol (MeOH) and Fischer-Tropsch fuel (FT) has been examined. Based on the hypo
In parallel with the changes observed in the world of work, the scope of occupational health and safety should be understood in a way that encompasses psychosocial risks. This necessity stems from the principle that occupational health and safety should be dealt with through a dynamic approach and finds itself a place in the national and international legal order. The scope of this thesis in terms
