Driftoptimering av effektkondensatorbatterier och transformatorer på mottagningsstationer

Denna rapport innehåller en utredning av effektflöden på Uddevalla Energi Elnät AB:s mottagningsstationer och optimering av driftläggning för dess effektkondensatorbatterier och transformatorer.Uddevalla Energi Elnät AB har sedan 30 år haft effektkondensatorbatterier inkopplade nästan hela året och dessa behöver av åldersskäl snart bytas ut. Uddevalla Energi Elnät AB har därför behov av nya rutiner för driftläggning av effektkondensatorbatterier efter det att Svenska Kraftnät och Vattenfall AB har infört nya regler för de reaktiva effektflödena i elnätet.I utredningen om effektkondensatorbatterier har det gjorts en investeringskalkyl med tre alternativ för inköp. Alternativ 1 med central faskompensering på mottagningsstation, alternativ 2 med faskompensering på mottagningsstation kompletterat med faskompensering på abonnentstationer och alternativ 3 med lokal faskompensering på abonnentstationer.  Det framkom i utredningen att alternativ 2: Central faskompensering kompletterat med faskompensering på abonnentstationer är mest lämplig att genomföra.  Det har tidigare konstaterats att det under delar av året har varit låg belastning på några av mottagningsstationernas transformatorer. Det har aldrig utretts om det är lönsamt att stänga av den ena transformatorn under hela eller delar av året.I utredningen om driftläggning av transformatorerna på mottagningsstationerna har det beaktats tre alternativ. Ett alternativ innebär att en transformator körs i tomgång utan last och ett alternativ med en helt avstängd transformator.

Ledande varumärke : Finns det det ett samband mellan ledarens agerande i företaget och varumärkets styrka?

The competition between brands on a market has led to a differentiation of the product range and the brands shape is more and more important to take consideration to.

Trygg i stadslandskapet? Ett exempel på genusperspektiv i stadsplanering :

Safe in the cityscape? Gender aspects on spatial city planning In this thesis, theories regarding gender and spatial planning are applied to the comprehensive plan Fortuna och Hemgården in eastern Malmö. Independent of factors like class, ethnicity and age women experience lack of safety to a larger extent than men do. Today, safety aspects on housing projects is scarcely a controversial issue, quite the contrary. However seldom are the central terms such as safety and security defined. Research has shown that women feel safe when they experience little risk of being subjected to violence; security is deeply interconnected with feeling safe.

Symbolers betydelse för barns läs- och skrivinlärning

AbstractThe aim of the thesis was to examine some older people's experiences of everyday life and how it is to grow old in Namibia today. Because everyday life is a broad concept, we chose to focus on some specific parts of everyday life. These are chores, family, work/education, elderly past and present and the government/society. Furthermore we chose to look at the similarities and differences between the experiences on the basis of gender, race/ethnic groups and class.We chose to use a qualitative research method and to be inspired by life stories. We used a semi-structured interview guide and interviewed six people between 70 and 89 years.

Pojkkrisen ur ett historiskt perspektiv : En studie av pojkars respektive flickors förändrade beteende, deltagande och resultat i skolan utifrån lärares historiemedvetande.

Popular culture is a phenomenon of growing importance in the society today. Children and teenagers are increasingly using popular culture in their everyday life to reflect and answer questions about their identities and the meaning of life. Swedish primary and upper secondary schools are expected to prepare their students for adulthood and to provide them with tools to explain understand and problematize contemporary society. From this perspective it is relevant to question whether the schools achieve this and whether the instruction given there represents the contemporary society. For the purpose of knowing more about how popular culture is perceived and dealt with in the Swedish education system, this study examines how eight textbooks in Religious Education (RE) and the national curriculum for upper secondary school discuss and treat popular culture.  The study focuses on when and in what ways the textbooks mention popular culture and if the curriculum provides any supportive base for including popular culture in religious education.

Bloggar och dagordningsteorin : En undersökning av bloggreferenser i fyra svenska tidningar under förvalsperioden 2006 och 2010

For the last ten years Internet has become more popular and is now used by most Swedes every day.  Internet has made it possible for many people to access a great deal of information about news all day long. Internet has also made it possible for people to create their own news and comment on happenings as they are taking place. One way to do this is to start your own blog, which is a kind of diary where you can publish your own thoughts about politics and news.In Sweden the media is often referred to as the third governmental power since the media is examining the government and people in power positions and bringing the people as consumers of news closer to the government. There is a theory called agenda setting that says that the media is an actor that shapes the political issues discussed by the people and politicians.In this essay I have used the agenda setting theory and linked it together with the Medias references to blogs in their news. This I have done to see if the media might be influenced by blogs.

Vägen till jämställdhet - Kvinnor i styrelserum eller män i förskolan? : En kritisk analys av den svenska jämställdhetsdiskursen

Equality between the sexes has been discussed in Sweden for more than 50 years. In the 60´s and during the 70´s the discourse that dominated the debate was based on the assumption that both men and women needed to liberate themselves from their traditional gender roles. In this approach information and education was perceived as the key to equality. During the 80´s however, power and subordination became the main focal point of concern within this debate, and focus upon changing the patriarchal power structures dominating society were perceived as the principal key for establishing equality between the sexes. Today, the latter discourse still dominates both the scientific and the political perspective upon equality.

Karlshamn-Wislanda Jernväg : Maktelit och nätverk i Karlshamns stad vid banans tillblivelse 1855-1874

The aim of this essay was to describe the power elite of the Swedish town Karlshamn, and its influences on the local political process before the realization of the narrow-gauge railway Karlshamn-Wislanda-Jernväg. During the mid 19th century, a revolutionary period began in the Swedish pre-industrial epoch. The political and institutional regulatory frameworks were disassembled and restructured, away from protectionism and centrally controlled administration, for the benefit of free trade, local self-government and liberalism. The changes were carried through during times marked by a drastic increasing native population and upcoming demands for adjustments to meet the growth of the industrial-, trade- and labour markets. An essential industrial development factor was the building of the national railway network, which started after some important decisions in the Swedish Riksdag during the 1850´s.

Samtalets helgd. En rekonstruktion av den svenska elitens demokratisyn

Democracy is said to uphold the dearest values and be the most moral system. But it cannot be characterized as a rigid "syste" but a continuously changing political framework, under which aims and values can be fulfilled - and replaced.The increasingly diverse and ever-changing environment of contemporary democracies forces change upon the systems' natural evolution, which makes their future features uncertain and unforeseeable. A powerful change-force doctrine does however claim change is mainly (or merely) caused by the power of ideas; the elite power over ideas can thus provide a natural foundation for the analysis of the direction of development for democracy. This study aims to provide such a foundation by reconstructing empirical and normative descriptions of democracy at two certain points in time, following extensive government studies.As a tool for analysis, this study identifies values of substantial and procedural character central to democracy theory and discourse. It further creates ideal types of democracy based on these values, to which the nature of democracy is measured.

Primärenergianvändning av passivhus i Sverige : Med fokus på Kvarteret Trettondagen

The building sector accounted for around a fourth of the total energy usage in Sweden in year 2010 (Energimyndigheten, 2012). Therefore it has become very interesting to achieve a lower energy usage in residential buildings. One way to achieve that is to build so called passive houses. By being very well insulated and have low leakage through the walls, they can reduce the energy usage for heating with a substantial amount. The first passive house was built during the 90?s in Germany; and in Sweden the first passive house was built in Gothenburg 2001.

Geopolitisk dynamik : Ett teoriutvecklande anspråk

In the social sciences, geopolitical theory is used in order to analyze states actions and commitments when it comes to foreign policy. This thesis develops a new understanding of geopolitical theory. Firstly, the development and application of geopolitical theory, from its foundations in the early twentieth century to contemporary geopolitical studies is discussed. Secondly a revised understanding of the variables integrated in the concept and how it can be operationalized as an analytical tool is presented and tested empirically.The critical assessment of the research field of geopolitical theory tells us that six different geopolitical perspectives have been considered the most influential (room, strategy, power projection, identity, affiliation and governance) when it comes to analyzing state action. This model is applied as an analytical tool and thus tested on a single case.

Underlag för BREEAM-certifiering : Kristianstad Nya Galleria

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.
