Förutsättningar att utforma stationsbatterier i vattenkraftverk med Li-jonteknik

In hydropower plants it is necessary to always have local power supply. Therefore, the plants are equipped with batteries as stationary back up power. Vattenfall Vattenkraft is using lead acid batteries but has been investigating alternatives to replace them. The aim of this study is to investigate the potential of using Li-ion technology as back up power.The study showed that Li-ion batteries have many qualities. The Li-ion technology will decrease the space and maintenance demand.

Energikartläggning av polishuset i Gävle : Åtgärdsförslag för ett minskat energibehov i fastigheten Gävle Söder 17:10

The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.

Erfarenheter från Olika Produktutvecklingsprocesser vid Utvecklingen av en Atmosfärisk Vattengenerator

This Master of Science thesis was completed at the Department of Machine Design at the Royal Instituteof Technology in Stockholm in collaboration with Lund Faculty of Engineering, Luleå University ofTechnology and Stanford University. At Stanford University a global product development project wasrealized as part of the course ME310. The project was initiated by the American company ImmerseGlobal whose vision was to develop a new type of Atmospheric Water Generators, a machine that absorbsthe moisture in the air and via a water system transforms it to pure drinking water. The project was partlyfinanced by the Product Innovation Engineering program, a Swedish research and development programfor increased innovation capability in organizations.In parallel with the global project in the ME310 course the product development process was studied inorder to compare it with a product development course at the Royal Institute of Technology, IPU. Thetwo courses are similar to each other in several aspects.

BILD OCH MATEMATIK ? TV? KREATIVA ?MNEN. Om interdisciplin?ra samarbeten i gymnasieskolans estetiska program

This study aims to provide a comprehensive understanding of interdisciplinary collaborations between Art and Mathematics within the Arts program at the upper secondary school level. Grounded in sociocultural theory, this study explores learning through language, action, and context, drawing on the works of theorists such as Lev Vygotsky (1995/2016), John Dewey (1897/2011) and Roger S?lj? (2020). Through semi-structured interviews, educators in both Art and Mathematics discuss shared subject content and explore opportunities and obstacles in fostering a collaborative culture within the Arts program at the upper secondary school level. The study reveals common subject content in Art and Mathematics suitable for interdisciplinary collaboration.

Problemanalys i limlinje med Contipress

Projektets mål har varit att finna orsaker till delaminering av lamellimmade komponenter vid Stora Enso komponentfabrik i Ljusne. Detta resulterade i en analys av de faktorer, både material- och tillverkningsmässiga, som kunde bidra till en försämrad limfogskvalité. Analysen baserades på standard SS-EN 13307 ?Timber blanks and semi-finished profiles for non-structural uses?. En av de gällande faktorerna som analyserades var presstrycket vid limning.

Upplevelseproduktion som en lärandemetod: En litteraturstudie om hur upplevelseproduktion och pedagogik kan kombineras till ett nytt koncept för framtidens lärande

Uppsatsens inledning börjar med att introducera läsaren till arbetet med en presentation av ämnet och varför det är av intresse samt en beskrivning av utbildningen för upplevelseproduktion. Vidare presenteras de teorier från upplevelseproduktion som berör arbetet samt viktiga teoretiska delar om generationer, pedagogik och lärande samt Human Dynamics som ligger till bakgrund för arbetet.Syftet med arbetet är att kombinera teorier om upplevelsesamhället och upplevelseproduktion med pedagogisk teori för att ta fram ett koncept för framtida lärande som är mer individanpassad och hänsynstagande till elever med särskilda behov.För att kunna svara på de framtagna forskarfrågorna:?Vilka teorier om upplevelsesamhället och upplevelseproduktion kan appliceras på individanpassat lärande??Hur kan detta kombineras med pedagogisk teori och tillsammans stärka ett individanpassat framtida lärande?? har det genomförts en litteraturstudie och vidare en konceptutveckling.Studien har genomförts för att visa att det finns likheter mellan teorier från upplevelseproduktion och pedagogiska teorier. En kombination av dessa teorier kan underlätta lärandeprocessen inom skolan. Även organisationer eller projekt som till exempel Framtidens lärande kan utvecklas med hjälp av nya kunskaper de inte redan besitter om lärande..

Ingmar Bergman och musiken : En audiovisuell analys av Såsom i en spegel, Tystnaden, Persona och Vargtimmen

The research on Ingmar Bergman is comprehensive, however, there is one aspect of his artistry that has been regrettably neglected ? his use of music. Music always played a huge part in Bergman?s life, and it was also a great source of inspiration. The music was a structural component in the creating process and he often referred to his films as pieces of music and his actors as musical instruments.

Bjälklag i FRP-material

Syftet med detta examensarbete är att vidareutveckla glasfiberbalkar så de kan användas som mellanbjälklag i småhus. Förebilden var ett ?Delta Deck? som utvecklats av Altakor Group och används i brokonstruktioner. Denna profil har vi sedan modifierat och optimerat för bruk i småhus. Den största skillnaden är att vi valt att inte använda den så kallade ?snap-fit?-tekniken.

Windows, RedHat och IPv6 : ett test!

With the huge amount of computers connected to the Internet the IP-addresses are starting to run out. The Internet Engineering Task Force, IETF, have decided that it is about time to exchange the old 32 bits Internet protocol, Ipv4, to a more modern 128 bits protocol called Ipv6. This thesis explores the possibility to install Ipv6 in different operating systems. By testing various operating systems and by set up criteria compare them to each other we give the reader a picture of how the installation is done. We also show which operating systems to prefer if you want to use IPv6.

Evigt offer eller alltid gärningsman? : Framställning av invandraren i den nätbaserade dagspressen

The purpose of this study is to examine how immigrants are portrayed in the Swedish daily newspapers online reporting. The essay investigates in what context immigrants, as individuals, are made visible and how they and their origins are reproduced. The study focuses on the roles victim and aggressor, and is also investigating potential differences between morning and evening newspapers.Present theories are discursive discrimination, critical discourse analysis, cultural racism, stereotypes and structural discrimination. Adopted methods are qualitative and quantitative content analysis, based on the Global Media Monitoring Project-tool.The results show that immigrants are not individually stereotyped or depicted negatively, but that their immigrant origins often have a central part of the story, that they are mentioned mainly in connection with negative news and that negatively charged words occur frequently. .

Hörselnedsättning hos för tidigt födda barn ? En litteraturstudie

A stay in the neonatal intensive care unit of greater than 5 days is one of the identified risks ofa sensorineural hearing loss. Preterm infants usually have at least one risk factor for hearingimpairment. The period from 25 weeks' gestation to 5 to 6 months of age is most critical tothe development of the auditory system. We think it is important to investigate hearingimpariment among infants born preterm, degree and type of hearing loss, risk factorsassociated with hearing loss and how the auditory system may be affected by preterm birth.ObjectiveA critical review of the current literature including studies of preterm infants born betweengestonal age 25-37. Our aim is to identify the most common type and degree of hearing lossamong infants born preterm and if there is an association between hearing loss and pretermbirth.MethodA literature search of Scopus and Pubmed resulted in 16 articles from 2000-2015ResultsMost of the infants in this study had a severe to profound sensorineural hearing loss.
