Effektiviseringspotential inom industrisektorn : Energibesparing vid frekvensstyrning av centrifugalpumpar ? en fallstudie

The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variablespeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..

Den Digitala teknikens påverkan på resebranschen och dess marknadsföring

The intention of this essay has been to investigate how the new digital technology has affected the tourism industry and marketing, as well as how travel agents and tour operators adapt to this. We also aimed to get a broader view of how the future might look like when it comes to marketing and virtual service landscapes. We decided to base our research according to these following four questions:? What affect travel agents? way of adoption to the technical development?? What purposes do the travel agents have for building up their virtual service landscape?? How much does the travel agents emphasize on digital marketing?? What can travel agents do to better adapt to the technological development in the future?We have chosen to use a qualitative research for this essay. The reason for choosing a qualitative research was to gain a wider understanding that would represent a big part of the changes of technology development.

Ekologi som kommersiell vara

Organic cotton has been in the medias field of vision for quite some time. This interestalso reflects in a growing awareness in the textile industry where more and morecompanies today offer organic cotton in their product range. With this in mind wequestion whether organic cotton has become a viable commercial product. We alsoacknowledge there is a lacking of understanding the complex problems that organiccotton manufacture involves, for example the huge effort and cost required for a transitionfrom conventional to organic cotton farming.The purpose of this paper was to study how textile, ecology and competition today arebeing combined by companies. We wanted with our investigation to find out whethercompanies in the textile industry use ecology as a competitive advantage.

Mikrosensorer i nätverk

The purpose of this thesis is to investigate the possibility to make small, cheap and ultra low power sensor platforms, connected in wireless networks for monitoring of home and industrial environments. The concept is based on ideas from our supervisor, Jerry Lindblom. The developed system consists of a generic platform for different sensors, a receiver and software. A GPRS module from RO Rollytech AB and a database from Gema Industri AB have been modified and used to demonstrate an example of a complete system. To the platform, it is possible to connect any resistive sensor and any sensor that can act as a switch.

Utvärdering av miljöarbetet vid nybyggnad av butik : miljöledning och avfallshantering

According to recent statistics the construction industry is responsible for the largest waste discharges of both dangerous and non-dangerous waste, when disregarding the "non-dangerous" amount of granite waste produced by the mining industry and the waste produced by the pulp and paper industry. Preventive work within waste management is an ongoing practice so to be able to reduce negative environmental effects. One of the most common actions for the companies to take is to separate the different kinds of waste from one another at the construction site. Although by working with the problem in earlier stages of the process a large amount of the waste could already have been reduced.Companies in the construction business that are actively working to decrease environmental impact in their operations often use an EMS (Environmental Management System). By using environmental management as method the company can manage their environmental work so that actions can be taken where they are needed the most.

Glasklart? En kvantitativ studie om en inglasad exponerings påverkan på kunden

Shoplifting is a serious problem due to the fact that about 2 % of a retail store's turnaround dis-appears annually. This paper discusses the problem with shoplifting where a closed retail display of glass can prevent this kind of misbehavior. Hitherto the scientific research regarding how consumers react to a closed retail display is non-existing. With this in mind we want to investigate and enlighten the phenomenon regarding consumer behavior and product appreciation. The study is carried out at a retailer in the beauty industry in Sweden both in stores where the selection of perfumes have been displayed behind glass and in stores in which they have been displayed with open access.

In order to answer our question we have chosen to use a qualitative approach in which we have interviewed three people. These three people all have deep and thorough insight in the Wallenberg family.

Matregionen Södra Roslagen : en etnologisk studie om lokala beskrivningar av en regions mat

North of the city of Stockholm lies the area called Södra Roslagen composed of several municipalities. The purpose of this essay is to discover how local informants describe the food culture of the region and analyse why some types of food are mentioned and others are excluded. Several people within the food industry of Södra Roslagen were given surveys asking them to describe the food habits of the area, from commodities and certain dishes to traditions. These answers were analysed using the theories regional food, regiocentrism, revitalisation, placeless food and the idea of viewing culture through the long and the short perspective.One informant mentioned that professionals in the food industry of the region tend to follow trends from the rest of the world and another that many producers work with ecological requirements. Södra Roslagen was also defined by some as having a taste of summer as this coastal area sees an influx of visitors during that season.

Bungenäsmöbeln : ett examensarbete för Skälsö Arkitekter

The essay describes the bachelor project by Marie Hanås, in collaboration with Skälsö Arkitekter. Skälsö Arkitekter are currently developing an area in the north of Gotland, Bungenäs; previously home to lime stone quarries and military bases.The brief was to design a set of outdoor furniture to complement the new development. The main effort of the project was in designing furniture that would fit the environment visually but construction issues were a major secondary concern, to ensure the easiest possible manufacturing. A reference group of coastal house owners were interviewed, and their feedback, together with an analysis of functions, trends and target groups, were the base for the ideas.Of the five concepts presented, Skälsö Arkitekter chose one to develop further. This was done through sketches, models and 3D models and led to the final result which is lightweight furniture of Gotlandic pine wood with an industrial touch.
