Utvärdering av öppna dikens status och funktion : en förstudie i Västmanlands län

Evaluations of open Ditch status and function, with an assessment of suitability of a conversion to a two stage ditch as a low maintenance alternative. To illustrate Swedish drainage problems this work focused on two agricultural drainage associations assessed in detail with a new method called MADRAS (Minnesota Agricultural Ditch Reach Assessment for Stability). With the assessment of the MADRAS method estimates were made to conclude the ditches operating problems. This was made through measurements of sediment depths, mass bank failures etc. in order to quantify ditch problems and propose practical actions for improved ditch stability and water quality. The MADRAS surveys were conducted in two main ditches that drains 2900 hectares of land on the northern shores of Mälaren. In the study measurements of the ditch cross-sections were also conducted to compare actual profiles with the original map profiles. The evaluation showed that parts of the studied ditch sections were operatively poor; main reason was mass bank failure, undercut channel banks, sediment aggregations and narrowed ditches. The profile survey shows that a majority of the profiles 80 % has sediment accumulations there remains only 64 % of the original profile from the map.

Fuktskydd och planering i byggprojekt ? Erfarenheter från Eolshäll

When the Eolshällproject was completed for the first time, a great deal of moisturedamage was discovered. Therefore the structure completion was removed andreinstalled. The project was originally planned to cost a total of 126 million SEK, but thefinal costs landed on 271 million SEK. What caused this failure? Were the designs poor,was the technology used too advanced, or was the project not managed properly?Based on the Eolshällproject, theses will be presented about what may have caused themoisture damage.

Samverkan på Järnvägen : Samverkan för arbete med Förebyggande Underhåll

Under litteraturstudierna fick författarna en uppfattning om att järnvägsbranschen är präglad av en hel del problematik som visat sig i ett flertal brister. Flera större omorganiseringar hade skapat en bransch med otydliga ansvarsgränser och otydliga roller med en mängd utdragna rättsliga tvister mellan beställare och entreprenörer som följd. Stämningen beskrevs som dyster och kompromisser mellan järnvägsaktörer förekom inte i den mån som behövdes, utan aktörerna tänkte mest på sin egen verksamhet. En ändring behövdes.Rapporten är begränsad till tre nyckelaktörer med koppling till järnvägsunderhåll: beställare, entreprenör och trafikutövare. Fokus har lagts på det alltför förekommande avhjälpande underhållet, som visar sig i form av trafikstörningar och trafikstopp.

Uppföljning och analys av Stockholms stads solcellsanläggningar

During 2007 the City of Stockholm installed five grid connected photovoltaic systems. The aim of this master thesis is to quantify the amount of produced energy and recommend routines to collect and analyse production data, to make production data accessible by the public and to gain experience for future installations.The total amount of produced energy until March 2009 is 227 000 kWh, with an annual rate of 150 000 kWh. The expected annual rate was 148 000 kWh.All system owners are positive about their plants and see economical benefits in scaling up such systems.The installations need very little attendance and maintenance, however it is recommended that an alarm function is installed for automatic feedback in case of a system failure. All future systems should be inspected during full operation to determine if the actual capacity is matching the installed capacity..

Hur kan mikroföretag bygga upp varumärken? : En studie av vilka faktorer ett mikroföretag kan använda vid uppbyggandet av sitt varumärke.

The purpose with this essay is to study how a micro enterprise builds a brand. This because the current situation makes it difficult to stand out from the vast amount of marketing messages available in the market without having an extensive marketing campaign. Small companies do not have the opportunity to put a lot of recourses as money into marketing as the large companies do. Neither do they afford to repair a brand failure.Brand building is a process that constantly is in progress in a company, large or small. To make this process concrete we have chosen to study the four factors; brand awareness, perceived quality, brand associations and brand loyalty.

Meeting, greeting & seating : a design proposal for Magomeni garden, Dar es Salaam, Tanzania

More than fifty percent of the world population today lives in cities, and the pressures of urbanisation are particularly present in developing countries. As landscape architects, it is important to gain knowledge about the effect of urbanisation and ways to prevent the negativities. Experiencing the effects in person in a developing country, as well as learning from and about other cultures, enhances the understanding for global situations. Dar es Salaam is located in one of the most rapidly urbanising regions in the world, which puts pressure on the environment and the humans living in it. Lack of means to regulate land development has led to a situation where expansion of unplanned settlements occurs, with spatial disorder as a consequence. This has in the extension led to a decreasing amount of publicly available and qualitative green spaces, and degradation of the few ones that exist. There are facts that strengthen the status of urban parks, which especially becomes relevant in developing countries where many people live in sparse and exposed conditions.

Undervegetation : användning av vedartade marktäckare i anläggning

The use of the robust and durable woody ground covers is increasing, not in the least in public places. The group includes low shrubs of different height that effectively build low, tight vegetation that covers the ground. Despite all the good qualities the knowledge about them is quite low and there are ideas about them of being dull. The woody ground covers manage to struggle against weeds effectively by competing for nourishment and water, but above all, by the canopy of the ground covers that prevent the weeds from getting enough light. In that way the woody groundcovers can effectively compete with the annual weeds.

Att rädda världens djur : en retorisk analys av Parken Zoo:s kriskommunikation

Crisis communication can make a crisis turn into a double crisis. The purpose of the thesis is to analyze by which rhetorical means a double crisis can occur. With the Swedish zoo Parken Zoo as a specific example, this essay examines the crisis communication during the crises that started with the tv-show Kalla fakta. The tv-show revealed that Parken Zoo killed and slaughtered endangered and sacred animals. When asked about the specific animals, the head of the zoo gave different answers ? which contrasted with former employees testimony.

Chalmers University of Technology

The Division of Language and Communication at Chalmers uses a web-based language tool, named EngOnline, to teach English grammar. The language tool suffers from some shortcomings. These include stability problems and an outdated interface but, above all, there is no documentation. Because of the lack of documentation and EngOnline?s need of maintenance, the Division of Language and Communication has decided to replace the language tool with a new and well documented one.The new language tool was developed using an agile work process; detailed documentation was replaced with more efficient communication.

Arbetsrationalisering genom samarbete : en fallstudie

To be a part of the future we have to make a profit, one way to improve the profit margin is by reducing the fixed costs. This paper discusses the financial results of equipment cooperatives in crop production. Through a case study of three farms in Södermanland, we have an example of how it can look today and how it could look tomorrow. The three farms are crop-producing farms with slightly different orientation. Jursta Gård, 155 hectares, and Djursnäs Säteri, 215 hectares, have grains crop and oilseed crops as the main crops, and Nibble Gård, 340 hectares, mostly have pasturelands and some grain crops.

Utveckling av internt Administrationssystem

This thesis work is executed at Business Unit Ericsson Test Environment (BETE), in Linköping. BETE is the department at Ericsson, which is responsible for the operation and maintenance of the company's Operations Support System (OSS). Their management system was outdated and they wanted it to be updated and it also required new features. The database needed to be replaced and the data migrated to a new database without licensing costs. The system also needed a part where employees could manage existing users.As a programming language PHP was chosen for its dynamic possibilities, platform independence and good support for database intergration.

Plan för implementering av strukturerat underhållsarbete på Valmet ABs gjuteri i Karlstad

Rapporten handlar om att sätta upp en plan för implementering av ett mer strukturerat underhållsarbete på Valmet ABs gjuteri i Karlstad. Arbetet görs i kursen examensarbete för högskoleingenjörsexamen i maskinteknik på Karlstads universitet under våren 2014.Valmet har nyligen köpt upp gjuteriet på Lamberget i Karlstad. Där är det ett mycket eftersatt underhåll och finns i nuläget inte någon bra struktur på hur de arbetar med underhåll. Underhållsverksamheten är i behov av att systematiseras och integreras i Valmets övriga underhållsorganisation.Syftet med arbetet är således att utarbeta en plan för att strukturera underhållet på Valmets gjuteri i Karlstad.Arbetet är indelat i tre faser.- Nulägesanalys genom dels intervjuer av underhållspersonal samt kartläggning av utrustning- Skapa en målbild över hur man vill arbeta med underhåll, genom studiebesök hos andra liknande verksamheter, diskussioner med ledningen samt litteraturstudier.- Upprättande av plan för hur man ska ta sig dit. Vilka aktiviteter som skall utföras samt i vilken ordning, där bland annat lämpliga mätetal ska tas fram.Arbetet är baserat på metodiken TPM (total productive maintenance), det handlar dock inte om ett fullständigt införande av TPM utan begränsat till valda delar.Utifrån intervjuer med underhållspersonalen på gjuteriet samt observationsstudier och en kartläggning av maskinparken har en nulägesanalys gjorts.

Expander : En studie av Expanders kommunikation och varumärke

Communication can be heard in many different ways and it is important for all businesses, especially in B2B. The construction and maintenance of a brand plays just like the communication a very important part. These parts also have a lot to common and affect each other in a large extent. One problem that may occur in many companies is the failure to grow and gain a larger share of the market even if they in various ways are trying. Expander is one of those companies and in this research report we studied communication and brand building, focusing on brand management, relationships and integrated marketing. Here we drew the conclusion that all these areas are important for a company, especially in the Business-to-Business marketing in different ways.
