Vätgas har potential i ett energilagringssystem eftersom det är en energibärare som är väldigt energirik och kan lagras i stor skala. Vätgas kan produceras enkelt via elektrolys av vatten och lagras i stora mängd under högt tryck, vid behov kan vätgasen sedan brännas i en kraftverksprocess och generera elektricitet. Då förbränning av vätgas med syrgas enbart bildar vattenånga kan ett förnybart eneHydrogen gas has potential to function as an energy storage solution due to its high energy content and its suitability for large scale storage. Hydrogen can be produced by water electrolysis and can be stored in large scale under high pressure, when needed the hydrogen can be burned in a thermal power plant to generate electricity. Since combustion of hydrogen with pure oxygen only yields steam,

Syftet med denna studie är att hitta vilka möjligheter detaljister bör fånga för att förbättra den komplexa inköpprocessen i butik, genom att integrera online-kanaler. Detta för att möta kundens krav i den ständigt föränderliga multi-kanal miljön.

Populärvetenskaplig sammanfattning Gallring är en viktig del i det moderna skogsbruket. I Sverige har gallring skett i ca 150 år och i början av 1900-talet ökade intresset då pappersmassaindustrin tog fart. Detta ledde till ett ökat intresse för mindre träd och successivt så ökade behovet att utveckla strategier och gallringsmetodiker. I Sverige genomförs gallringar med 10-25 års intervall och manThe aim of this study was to investigate the growth of individual trees and the effects of thinning in a stand of spruce and pine. This was made through tests of regression between a competition index (CI), which depended on distance and diameter of neighbouring trees, and needle mass (NM), compared to basal area growth (BA growth) and dry-weight. The data used in this study was collected over the

This report presents how far NCC current VDC tools and methods in building construction can be implemented in road and infrastructure projects also what new tools, methods that can be created helped by pre-selected software’s. VDC is well developed within the construction of building and research and resources in the field have been spent under a longer period of time unlike in road and infrastruc

The aim of this master thesis is to investigate ideas in the Swedish debate about e-books in relation to Litteraturutredningen (2012), with focus on ideas that concern access of e-books within the public library. Access is discussed in relation to Buckland’s (1991) six barriers of access of information and Habermas’s (2003) democratic public sphere, as well as the Swedish Library Act (2013:801). I

Målet är att undersöka hur en ökad installation av solceller kommer att påverka lågspänningsnätet. Öresundskraft efterfrågade en rapport som undersöker framtida problem i deras nät när solcellssystem installeras i större omfattning. Scenarion där olika procentantal kunder i lågspänningsnätet installerar solceller har analyserats och simulerats. Två olika lågspänningsnät har används, ett område påThe goal of this report is to examine the impacts of integrating Photovoltaic systems in low voltage networks. Öresundskraft requested a report on what problems can arise in the future as more and more people start using PV systems. Scenarios where a certain percentage of an area will install PV systems have been simulated, as well as further analysis of the results from the simulations and calcul

Sedan hösten 2006 har lagstiftningsprocessen fått ett nytt inslag. Ett oreglerat och nästan okänt inslag, men ack så viktigt. När de fyra borgerliga partierna under åren 2004-2006 förberedde ett eventuellt regeringsskifte efter valet 2006 så var den s.k. Äntringsstyrkans arbete mycket viktigt. Ett av deras viktigaste förslag var att en mekanism för all samordning mellan de fyra partierna skulle inSince fall 2006, the legislative process has a new element. An unregulated and almost unknown element, however very important. When the four center right wing parties during the years 2004-2006 were preparing a possible change of government after the 2006 election, the work of the so-called “Äntringsstyrkan” was very important. One of their main proposals was that a mechanism for all coordination

Urbaniseringen i världen har de senaste 60 åren accelererat, och folk bor numera allt tätare och spenderar större delen av livet inomhus. Samtidigt pågår en trend av ökad psykisk ohälsa i många länder, där urbaniseringen kan vara en påverkande faktor. Studier visar att närhet till natur gör oss mer välmående. Ett sätt att uppnå detta inomhus är att ha inomhusväxter. Dock är ett problem med att ha Urbanization in the world has during the past 60 years accelerated, resulting in people living in more densely populated areas and spending a majority of their lives indoors. Another ongoing trend in many countries is an increase in mental health issues, where urbanization could be a contributing factor. Studies have shown that closeness to nature increases our well-being. One way to achieve this

Library 2.0 is a term which emerged a few years ago and is frequently discussed. There is no uniform definition of the term but the central aspect of the concept is to encourage increased participation from library users. The aim of this Master's thesis is to investigate if and if so, how the professional role of the librarian is affected by Library 2.0. To do that, we have conducted a case s

The pursuit for equality between men and women is an ongoing struggle. One of the largest differences between men and women in general is the amount of time spent taking care of children and the home. This difference between men and women is one of the reasons women have less opportunity to pursue a career, be financially independent or take part in politics in most parts of the world. This differ

The aim of the article is to present a model of causal relations that is based on what is known about human causal reasoning and that forms guidelines for implementations in robots. I argue for two theses concerning human cognition. The first is that human causal cognition, in contrast to that of other animals, is based on the understanding of the forces that are involved. The second thesis is tha

We celebrated our 60th anniversary in October 2024. In the autumn of 1964, Carl-Axel Acking, Bo Adamson, Carin Boalt and Sten Samuelson were appointed professors at the newly formed Department of Architecture in Lund. They were tasked with starting Sweden's third architectural programme and building up research in the field. They succeeded very well, and now 60 years later several thousand archite
