Syftet med arbetet var att framställa en beräkningsmodell som behärskar att beräkna ett klimatsystems energiförluster samt livscykelanalys, LCC. Samt att använda denna modell vid jämförelse av två befintliga system.Modellen skapades i programmet Excell och använder sig av angiven indata för att beräkna resultat. Den användes för jämförelse av fyra lokaler i VIDEUM ABs byggnader. Två kontor och två föreläsningssalar jämfördes. Den beräknade skillnaden i energiförbrukning kunde i huvudsak härledas till det ena systemets längre drifttid över helgen samt att ett av kontoren drevs med högt konstantflöde hos ventilation även under frånvaro.Huruvida styrning av system sker efter koldioxidkoncentration eller temperatur verkar spela mindre roll för systemets förluster.

The implementation of a material requirements planning system is a complex and demanding task. There has been much research into what factors are important in such implementations, but seemingly very little about the links between critical success factors and management control systems. This thesis attempts, through a case study, to answer the question of how management control systems affect the implementation of an MRP system in ASSA AB, a Swedish manufacturing firm. Data is primarily collected through interviews. Theory regarding implementation success definitions, critical success factors as well as management control systems is presented.

Recent corporate challenges require effective communication in order to secure a company?s reputation. Companies as a result, need to be committed to a series of corporate social and environmental practices along with their financial commitments to their shareholders and investors. In fact, businesses are required to go above their ordinary operations and involve all potential stakeholders that can be affected by their strategies. Companies also need to communicate social, environmental and economic consequences of their activities along with their CSR commitments to their internal and external stakeholders in order to make a better corporate image and improve their market opportunities.

Denna uppsats är skriven som en studie i fyra delar. Första delen består utav redogörelser för syfte, metod och källmaterial samt hur jag skapat det analysverktyg som används i arbetet. I andra delen belyses krigföringens grundprinciper såsom de är definierade i litteraturen. Här redogörs även för de faktorer som kommer att användas vid identifikationen. Tredje delen av min studie inleds utav en historisk återblick, där jag återberättar händelserna som utspelar sig i Norge under 1942-1943.

Tendensen att försöka hitta de affärsmässiga argumenten (business case) för CSR (Corporate Social Responsibility eller företagens sociala ansvarstagande) började framträda på 1990-talet. Vetenskapsmännen insåg då att en enda forskningsdisciplin inte kan förklara hur företagens arbetssätt med CSR-frågor kan förbättra deras ?bottom line? och således bidra till en hållbar utveckling av samhället. Både teoretiker och praktiker har vänt sin uppmärksamhet mot framgångsrika företag (bästa praxis).  I korthet innebär ett business case inom CSR ett besvarande av frågan ?Vilka fördelar har företagen och samhället av CSR??.

En gruva kan orsaka stor påverkan på den omgivande miljön, bland annat påverkas grundvattennivåerna kring gruvan eftersom den länspumpas. För att få starta en gruva i Sverige måste tillstånd erhållas och då krävs en miljökonsekvensbeskrivning med bland annat en utredning om hur gruvan kommer att påverka omgivande grundvatten. Syftet med det här arbetet var att undersöka hur ett teoretiskt djupt vertikalt gruvschakt påverkade grundvattnet i det omgivande berget. Gruvan i den här studien antogs vara omgiven av sprickigt berg. Sprickigt berg har mycket heterogena hydrauliska egenskaper vilket gör beräkningarna av grundvattnets strömning komplicerade.Grundvattenavsänkningen beräknades dels med analytiska metoder, dels med numeriska metoder.

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

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.

This thesis concerns to investigate renovations of existing buildings aiming at enabling energy efficiency, from a conservation and restoration perspective. This includes performing case studies of three projects in the Gothenburg area where renovations has been done and an analysis of directives raised by the EU and later implemented by the Swedish National Board of Housing, Building and Planning, Boverket. In addition to these, regulations enforced by the Swedish law, related to the topic, have been considered.The investigated projects in this case were the housing cooperative Välten in Brämaregården, the Solar Buildings in Järnbrott and Gårdsten as well as Katjas Gata 119 at Backa Röd. In order to measure and compare the results of these projects a comparison between the pre- and post-restoration energy consumption have been performed. To capture additional perspectives the grading system Operation Kungsörn has been applied.Regarding the comparison of energy consumption the renovation of Katjas Gata 119 was found preferable but showed in my view lacking attention to the cultural heritage of the area.

The purpose of this thesis for Sapa Heat Transfer is to examine a furnace in which aluminium is pre-heated before hot rolling. The project is modeled in a computer environment in which the air flow in the furnace and the heat transfer to the aluminium solids are included. The computer environment and its governing equations, as well as boundary conditions and generalizations, are presented and explained.The simulations are based on two models. The first model has an asymmetric solid placement, which is how it looks in today's ovens. It is validated against collected data.

This report is focused on marketing opportunities for small-scale mango farmers in the Nyanza Province in Kenya. Kenya is a large horticultural producer in the world. Horticulture is an important income for a large share of the rural population in Kenya but profitability is low due to inefficiencies in marketing systems and poor infrastructure. The conditions for growing mango in the Nyanza Province are very beneficial and there are two harvesting seasons. Mango offers good income opportunities for small-scale farmers in the Nyanza Province.The aim of this study is to identify marketing conditions that will enable prospering business for small-scale mango farmers in the Nyanza Province, Kenya.

Denna C-uppsats syfte är att undersöka hur Case Management (CM) samverkanspartners: socialtjänst, frivård, Missbruks- och beroendeavdelning samt tre vårdcentraler, i Luleå kommun upplever den gemensamma samverkan. För att besvara syfte och frågeställningar har intervjuer genomförts dvs. en kvalitativ forskningsmetod eftersom att avsikten är att beskriva upplevelser. Det insamlade empiriska materialet grundar sig på tre individuella intervjuer samt tre gruppsamtal ? totalt tolv intervjuade.
