Mark röjd från sten : En studie av förklaringar och tolkningar kring röjningsröseområden

AbstractThis essay discusses different explanations and interpretations of what characterizes large areas containing clearance cairns (cairn fields). Results from the analyses show that there are different explanations about when and why cairn fields and clearance cairns occur. Explanations vary from introduction of the wooden ard in the early Bronze Age to the introduction of rational hay-making in the Roman Iron Age.  There is, anyway, relative agreement considering why and when cairn fields were abandoned. The reason suggested is an increasing pasturage with the consequence of reducing soil to poverty during the period of the Great Migration or in the Viking Age.The most likely cultivation system in cairn fields is a system consisting of both intensive and extensive characteristics. The latter coincides with the probable mobility of settlements.

Att erbjuda sanningens ögonblick : En undersökning av bokförlaget Novellix kommunikation och koncept

The Library of Uppsala University has decided to change their classification system from the Swedish SAB system to the American Dewey Decimal Classification. One of the main reasons for this decison was that Kungliga biblioteket also has made an exchange between these systems. Due to that, the national bibliography of Sweden classifies Swedish documents according to Dewey Decimal Classification and the SAB system is no longer maintained. A transition to Dewey Decimal Classification will enable Swedish librarians to import foreign catalouge posts and classification codes and will provide them with a common standard between their libraries and other libraries due to the use of the same international classification system. It is disputed whether the Dewey Decimal Classification is equally suitable for all subjects.

En Kommunikations Illustration : Interaktionen mellan deltagare i ledarlösa samarbeten

Purpose: The objective of this study is to illustrate how participants in leaderless based projects communicate with each other. Several studies have focused on technology-supported projects, such as open source projects, with an established project manager and goal. There is a lack, to the best of our knowledge, in studies that deal with the communication pattern in a leaderless computer supported collaborative project.Method: We have chosen to use a quantitative method where we systematically group several messages according to their content. This method was used in a similar study to illustrate the communication between participants involved in an open source project. We have taken the same Kripendorff based method and adapted it to our study by adding more descriptive variables.Theoretical perspectives: Manuel Castell discusses the aspects of a new communication power that is rooted in the individual as part of a larger creative audience.

DDC:s avdelning 150 : en analys av psykologins klassifikation under perioden 1932-2011

This master?s thesis focus on Dewey Decimal Classification during the period 1932 to 2011, where the classification of the psychological knowledge domain is analyzed and discussed. In the light of the recent swedish switch from the swedish classification system SAB to DDC, this research area deserves prominence. The aim of this study is to investigate how DDC represents the historical development of the psychology subject with its underlying epistemology, to identify and analyze values and prejudice, and to analyze problems with DDC?s classification of psychology in relation to three other classification systems.

Utvärdering av nya metoder för att finna och värdera risker i ett system

Examensarbetet är utfört vid BAE Systems Bofors AB i Karlskoga. Projektet har gått ut på att utvärdera den nya teorin STAMPoch testa det tillhörande verktyget STPAinom säkerhetsarbete mot det avgränsade ARCHER-systemets delsystem granatgrip-/lyftdon.I dag blir systemen mer och mer komplicerade och de nuvarande metoderna har inte utvecklats i samma takt för att göra en grundläggande säkerhetsanalys då många av olyckorna härrör från oförutsedda interaktioner. Teorin och verktyget är en nyutvecklad metod för att identifiera och värdera risker i ett system eller en produkt. Företaget har ännu inte satt sig in tillräckligt i professorn på MIT, Nancy Levesons rapport som ligger bakom denna nya metod för att arbeta med riskbedömning. Eftersom det är en relativt ny teori inom säkerhetsarbete så finns det inte speciellt mycket forskning att tillgå och antalet källor som finns tillgängliga är få.

Viking Eggeling och Diagonalsymfonin : en dematerialisering av konstobjektet

The aim of this thesis is to study Viking Eggeling?s artwork Diagonal Symphony together with Eggeling?s own art theoretical writings. This method of reading Eggeling?s art theoretical writings with the aim to try and create a deeper understanding of his art and especially Diagonal Symphony is a new approach in Eggeling?s art historical discourse. The thesis starts with a description of how the field of art history has understood Eggeling and his art primarily through art historical research aimed at Hans Richter.

En studie av hållbara alternativ till odlingstorv : - vid jordförbättring inom trädgård

Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.

Utveckling av automatiserade tester

Testning är den aktivitet där man verifierar och validerar ett IT-systems krav och exekverar det i syfte att hitta fel. Testning kan utföras både manuellt och automatiserat, genom att utveckla ett system som exekverar testerna åt sig.I detta examensarbete beskriver jag hur jag designar och utvecklar en IT-artefakt som automatiskt kan exekvera tester av ett annat system..

Google digitaliserar bibliotekssamlingar En analys av hur biblioteksvärlden reagerar på Google Book Search

The wide spread of the Internet and new information technologies in recent years has come to effect how libraries manage and disseminate information. Search engines like Google are widely used by people who often find the information retrieval systems of libraries to be too complicated. In 2004 Google announced plans to digitise five major library collections. Organisations representing the publishing industry and authors have since then filed lawsuits against Google claiming that Googles scanning of library books infringe the rights holders copyright. Due to Googles potential impact on libraries this thesis aims to examine how Googles digitisation project, Google Book Search, has been received in the library community.

Förstudiens betydelse : Granskning av ett stagnerat IT/IS-projekt på ett tillverkande företag

Vårt examensarbete har genomförts på företaget Electrolux Laundry Systems (ELS) logistikavdelning, Logistics Center Ljungby (LCL).  Under det senaste året har företaget haft motgångar vid ett IT/IS-projekt inom sin logistikavdelning (LCL). Uppsatsen har således syftat till att beskriva och analysera varför IT/IS-projektet har avstannat, och ej nått implementering. För att uppnå syftet har vi utgått från en, i stort sett, kvalitativ ansats där primärdata har insamlats genom metoder såsom intervjuer och deltagande observationer medan sekundärdata inhämtats i form av dokumentundersökningar och offentliga dokument. Resultatet av studien har utgjorts av deltagande observationer på fallföretagets logistikavdelning, LCL, samt intervjuer med olika verksamhetsnivåer. Detta har påvisat bristande kommunikation och direktiv samt fallföretagets brister i förstudiens utförande vad gäller förankring av projektet, planering av tid, resurser och kostnader samt formulering av krav.

Ekologiskt kopplade institutioner inom jordbrukssystemet :

The farming system is the basis of human existence through its production of provisions for man. By a continuous exchange of information, energy and material, between the ecosystems and the social systems, the farming system becomes an emergent property. The system's own properties, in the sense of farming methods, circulations and institutions, evolve through an adaptive process. Understanding this process and constantly learn from it, is the starting point for creating a sustainable development within farming systems. Thus, future farming system has to develop strategies that produce food provisions while at the same time takes into consideration the ecosystem's resilience and its integrity, but which also enables an ethical discussion. The institutions within the farming system are understood as links between the ecosystems and the social systems.

Den manliga heterosexuella normen En analys av SAB-systemet utifrån ett feministiskt och queerteoretiskt perspektiv

The aim of this Masters thesis is to conduct an analysis of the Swedish classification system the SAB-system from a feminist and queer theoretical perspective. The theoretical framework of the study is feminist and queer theory as well as theories from Library and Information Science, mainly classification theory. The study takes its departure from the idea of classification systems as social constructs, reflecting their time, place and society. Paul Ricoeurs critical hermeneutics is used as methodological guidance. This gives room for a critical perspective in the interpretation.

Effektiv kunskapsöverföring : Utredning av en avdelnings situation på ABB Robotics

The pace of product development is increasing. It is important to keep high quality in theproducts even though the time for product development decreases. Those companies whichcan utilize previous experiences are positioned with a significant competitive advantage. ToABB Robotics it has become evident that the knowledge transfer process within the productdevelopment department is inadequate. This study was a result and an attempt to address thisunsatisfactory insight.

Development of Liquid Cooling for PCs

In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.
