OPAC i moderna kläder ? en kvalitativ studie om olika generationers informationssökningsvanor och förväntningar på informationsåtervinningssystem

The purpose of this bachelor thesis is to find out how information seeking habits and experiences of people in different generations affects their expectations on information retrieval systems like OPAC. Two OPACs are used, one web-OPAC and one mobile-OPAC. The following questions are asked: how can theories about information seeking behaviors explain why and in which way one seeks information? In which way does information seeking behaviors and habits affect the experience of OPAC? Which differences and/or similarities can be found between the web-OPAC and the mobile-OPAC? How does generational aspects affect experiences and preferences in an information seeking context? The theoretical framework of the thesis is information retrieval with several models about information-seeking/searching needs and behaviors. The empirical data contains interviews with nine people in different generations and protocols about two different OPACs.

Adaptiv katalysatormodell för reglering

This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.

Realtidsoperativsystem på mätinstrument

Emwiro Vibe is a complete system for seismic measurements. The functionality of the system was before the completion of this project handled using a software contruction based on a state machine. Emwitech, the company developing Emwiro Vibe, expressed a desire to replace this solution with a real-time operating system (RTOS). The project consisted of two parts. Firstly the existing software was studied, available RTOSes was evaluated, and the RTOS most suitable for the application was selected.

Strömmar av vatten och politik - en studie om policyprocesser och anpassning.

One of the distinguishing features of successful societies is the ability to adapt to change, bothsocial but also natural changes like climate change. Climate change is a complex, dynamic,non-linear process with a great deal of uncertainty concerning the time perspective, risks andconsequences. A combination of factors like climate change, geographical vulnerability, adensely populated and highly built up coast line along with factors like deficient handling ofsurface runoff and a large usage of ground water leads to an increasingly vulnerable society. Italso puts a greater pressure on the society to have preventive measures in place.The number of actors working with preparing society to the expected impacts of climatechange and variability is increasing. However more than half of Sweden?s municipalities donot consider changing climatic conditions when planning, and many times even allow theconstruction of new living areas in known climatically vulnerable areas.

Fruits of knowledge : a case study of marketing strategies for small-scale mango farmers in the Nyanza Province, Kenya

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.

Konceptstudie av Waste Heat Recovery System på Tunga Fordon

In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.

Effekter av tidiga reflektioner vid musikreproduktion

In this project the focus has been on the system for recombination at Oskarshamn 2. The recombining systems have on several occasions switched paths due to low pressure before the last ejector that?s feeding the recombiner. Of the mentioned reason, events and several measuring points have been analyzed in this report since the installation of the recombining systems.In order to prove theories and demonstrate what may be the cause of this problem, we used heat balance calculations by the program Probera. Using the program, we can demonstrate that the catalytic process does not reach the desired temperature with the amount of combustible substance.

Aktivitet som sjukdomsmarkör på kalvar i gruppsystem :

Since long, Sweden has had exceptionally low calf mortality compared to most other countries. The tradition has been to keep calves in individual pens. With increasing number of cows per herd there is now a larger interest in more efficient and economical group systems for housing calves. However it has been noticed that bigger herds have more health problems and higher calf mortality than smaller herds. The early signs of disease are harder to detect when the animals are not fed manually.

Får vårdpersonalen bästa tänkbara IT-stöd? : Kartläggning och analys av informationsflödet mellan EPJ systemförvaltning och vårdpersonal

They should also care about the society and act in a responsible way.Problem discussion: Problems concerning CSR are that the internal part of the sustainability work has not encountered the same level as the external part of the sustainability work. Companies are today struggling with implementing CSR into their business strategies.Research questions:1. What does a company has to consider when working with CSR? 2. How can management control systems help the implementation of CSR into the organisation?Purpose: The purpose of this thesis is to examine what a company has to consider when working with CSR and how management control systems can help the implementation of CSR into the organisation.

Utvärdering av informationssystem vid företagsförvärv: Synergiers påverkan på informationssystems integrationsroll

The numbers of mergers and acquisitions have increased significantly in the last period of time. Although this popularity for mergers and acquisitions, most of the mergers and acquisitions fail to create value. One explanation to this failure of value creation is, according to several studies, how companies treat integration of information systems in the pre-merger evaluation. The research within the field argues that information system integration should have a proactive role in mergers and acquisitions, meaning that information system integration should support the organizational change and normally be considered in the premerger evaluation. The aim of this thesis is to study issues that affect whether companies choose to consider information system integration proactively, when involved in mergers and acquisitions.

Enterprise Resource Planning Systems as a Service: Hur genomförs en framgångsrik implementation?

Denna uppsats har sin utgångspunkt i den tekniska evolution som har skett i affärssystemens värld. Syftet var att undersöka och beskriva implementat-ionsfasen av ett Enterprise Resource Planning System som tillhandahålls som en tjänst via internet. Fokus var att identifiera framgångsfaktorer för implementationen med hjälp av ett fallstudiebaserat tillvägagångssätt där tonvikt legat på intervjuer och andrahandsmaterial. Undersökningen visade att bland annat valet av ett för organisationen passande system, en omfattande verksamhetsanalys, implementeringshjälp av konsulter samt anpassning av affärsprocesser är viktiga faktorer för en framgångsrik implementation. Därtill såg vi att en tydlig projektplan, en Project Champion och dedikerade resurser också var viktiga faktorer för framgång..

Kejsarsnitt på nötkreatur : indikation, frekvens och utförande

The background of this study is an article in the hunting magazine ?Svensk Jakt? where Karl Hedin claims that his sawmills has not noticed any significant moose damages in the timber. The purpose with the study is to find out the causes to the moose explosion and what it has led to in today?s forests. A questionnaire has been sent out to sawmills in the region Dalarna with the purpose of finding out if sawmills receive moose-damaged timber and what they think about how they foresee future development. There were two causes of the moose explosion, that had effects on the moose population. The first cause was that the moose hunters wanted to raise the moose population, and by raising the calf shooting and by saving the cows they succeeded. The second cause was changing methods in Swedish forestry.
