The presence of the absentMy project is based on the idea that we all leave something behind, traces which tell stories about us for others to read.I wanted to give these traces a value by collecting them in a book. My aim was to create pictures open enough so others can fill in their own stories.I used different methods to find ways to describe the absence: such as illustrations, installations and photos, oftendescribed in a sensitive way. I also changed the character of everyday objects to add a kind of awareness left by an earlier user of the object.By using my own imagination with inspiration from people I talked to, I created lyrics and pictures for the book. It has resulted in a 112 paged book containing my own interpretationsof other opinions about absence, along with short lyrics of various characteristics.Hopefully the book will make others more aware of the traces left in their own surrounding and bring up questions about human contact and how it can be identified.My question at issue was following:What kind of traces do we leave noticable for others?How can I translate an emotion to a picture?How will the choice of method affect the feeling of the absent?.
Arbete med utveckling av ett kartsökverktyg för nationell naturolycksdatabas
We have made a suggestion for a map based search tool used with a database containinginformation on natural disasters. The database is being developed by NCO (SwedishCentre for Lessons Learned from Incidents & Accidents).We examined both Swedish and international examples of databases on naturaldisasters. The examples that we found were often hard to get the hang of, due to poorcompilation. The problem, that is typical of the international examples, is that the processof data collection is not standardized, as it is performed by different organizations andcompanies with diverse demands on and needs for the database. Therefore, to keep itsymmetrical, there ought to be only one department with the overall responsibility for anational database on natural disasters in Sweden.The natural disaster we based our study on was the flooding in Arvika in the year 2000.We inspected the availability of data about the flooding, and found it to be satisfying.Through contact with the municipality of Arvika, by mail and telephone, and a visit at theArvika municipality office, we acquired reports on the flooding and the joint rescueoperation that followed, and also GIS layers showing the extension of the flooding..
Arbeta inteam(t) : En studie om team och teamarbete
AbstractThis is the paper you should read if you want to know more about working in team. Teamwork is a way of working and it increases more and more among societies and companies today, but it is not quite clear what the diffrences is from working in groups. We have in this paper tried to clear out the differences between groups and team, and we have also tried to give an oversight of how to work in team in organizations. Cultures of organizations, leadership and power and also development of qualifications are big parts of an organization´s daily work, and we have explained these concepts from a teamperspective.We have, in this paper, done interviews with people that have been in contact with the central consepts that we use. And then we have analyzed their answers with help from litterature, which we have closely studied, thereafter we have presented our results.
Bojkonstruktion
The division of Electricity at Uppsala University runs a project called Lysekil project, they have designed a buoy that uses the waves to create electric power from a generator attached to the bottom of the sea.Uppsala University is closely connected with the company Seabased and the university makes use of their facilities in Lysekil. When they designed the buoy issues occurred, the geometric design was flawed, brackets with a short shelf life and it is generally uneconomic.A study visit was done in Lysekil on Seabased facility. With this visit the project started, which is to improve the design of the buoy and the attachment of wires leading to the generator. In this project we have chosen to use a beam system with three beams that are attached to the buoy. Then a wire attached to a plate that sits between the beams will be leading to the generator. Two proposals for construction are created, what distinguishes them are the brackets between the beams and the buoy.From these constructions, the design that is considered most optimal for our project is chosen.All parts of the buoy have been modeled and the drawings are designed in ProEngineer software.The two constructions are compared with each other, but the whole focus is on the second and final structure. The report begins with an introduction describing Lysekil project, and a task description of our project.The project aims to produce an optimal buoy that will be easy to design, materials restrictive with good durability and an economical solution.Wave power true function has been studied, mechanical and finite element analysis of beams, buoy and plate design.This has been presented in this report, where in the various chapters can read more about the processes. Although the relevant facts and information on this project and buoy development is included.
Kommunikationsproblem och bemötande inom referenssamtalet
This bachelor thesis is about communication problems and treatment during the reference interview. The purpose was to investigate the reasons of why users? information needs are not always understood by the librarian and what to do about it. I have also investigated what kind of skills that can be useful for librarians to have and how a librarian can act in a way that makes the user feel welcome during the reference interview. The method I used was a literature study and an own study through interviews of library users.

Empirisk studie av den radiella förspänningskraftens variation i klassiska skärskruvförband
In this study, the pre-tension force in an insert screw connection are examined in order to establish a greater understanding of the system and to facilitate the process of making new metal cutting tools. Certain especially significant design variables such as the offset, the length of the contact thread and the shank length above the threaded hole, are selected to be closely examined. A comparison of the influence on the pre-tension force between threaded holes made with a worn, versus new, threading tool is also involved in the experiment. The study is limited to handling the screw sizes M2,5 and M3,5. The results show that a regression model, with good approximation, can be fitted to the measured values.
Förbränningslära för bubblandefluidbädd
Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report, the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.
Berättelser om livet, mödraskap och gruppen
In 2007 the Prevention Unit at Södermalm in Stockholm started a group activity for parents and children. The group activity?s intention is to offer families support in their early interaction. This study is a part of providing knowledge about this intervention. The purpose of this study is to describe and analyze the stories which are produced by five participants in a support group for parents and children.
Ledarskap på distans : Att arrangera och upprätthålla
This essay aims to create an understanding of how leadership can be arranged in a company that embraces new technology and telework, and how it can be experienced from the employees' perspective. In order to make it possible to investigate this purpose are three questions formed; ?How is the leadership perceived??, ?How does telework into motivation?? and ?How does telework into communication??. A presentation of previous research is given, focusing mainly within different types of leadership, distance, and telework. Based on this, three interviews was made in which respondents? experience of telework was in focus.
Underlag till energieffektiviserande åtgärder i nätstationer
Umeå Energi are working towards a goal, that in the year of 2018, they will be completely climate neutral. As a part of this, one target is to reduce their grid losses by 4 % of the 2012 level, which corresponds to an overall reduction of the grid losses of just over 1.7 GWh. In many residential areas, the distribution grid is designed and rated for electric heating as the heating in the houses. As many of the houses later has been converted to other types of heating, their electricity use has decreased and the total power output from many of the secondary substations has decreased significantly. Because of this, many of these stations today are well oversized, which in turn means that the energy losses in these stations are unnecessarily high.In this degree project, 25 secondary substations have been studied, all located in residential areas in and around central Umeå.
Energianalys av luftbehandling
Elanvändningen till ventilation har ökat med 40 % sedan 1990 i Sverige. Ventilationen är en miljöbov enligt undersökningar som visar att elanvändningen till ventilationssystemens fläktar kan reduceras. Minskning av elförbrukningen kan t.ex. uppnås genom utbyte av fläktmotor till en EC-motor eller till en fläkt med bakåtböjda skovlar och direktdrift. Effektivieringsåtgärder kan ge en lägre elförbrukning på upptill 50 % i vissa applikationer.Ventilationsfläktarna i Sverige förbrukar 12,3 TWh per år.
EG-rättens kontroll av företagskoncentrationer; en fusionskontroll i förändring.
Enligt rådets förordning 4064/89, om kontroll av företagskoncentrationer, är det kommissionen som kontrollerar och granskar företagskoncentrationer. Den så kallade ?one stop shop-principen? innebär att företag som genomför en fusion med gemenskapsdimension endast ska behöva vända sig till en instans, det vill säga kommissionen för att få en bedömning avseende fusionens förenlighet med den gemensamma marknaden. Eftersom kommissionen är ensam beslutsinstans är det därmed också kommissionen som har fått utforma standarden för vilken bevisning och vilka antaganden som anses tillräckliga för att bevisa att en skadlig företagskoncentration föreligger. Förstainstansrätten har sedan den installerades 1989 haft funktionen att handlägga överklaganden av kommissionens beslut i konkurrensärenden.

Fallstudie av kostnader i tornsilo och plansilosystem på en mjölkgård :
I have through a case study looked on a milkingfarm in Dalarna and been counting on
what it would cost to increase the silagestorage. Today they have to little capacity on the
existing towersilo because they built a bigger farm with more cows. The reason is that
two families decided to start having the production on one farm together and moved all
animals from one of the farms to the other farm. So for that reason I have looked on the
costs to build a new towersilo or levelsilo.
The goal has been not only to look at the buildingcost but also which operatingcost that
is included with the different alternatives. I have taken tenders from two different
towersilocompany, Bjurenwall and Svenska Neuero and taken tenders from Abetong for
a levelsilo with roof and one without roof.
The overall feed requirements on the farm is on 240 tonnes dry extract and the old
towersilo hold 110 tonnes dry extract so the need for a new foundation is on 130 tonnes
dry extract.
I have through cost estimate been counting on the specific buildingcost for each
buildingaltenative.
