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.

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.

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.

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.

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.

In health care today at Uppsala County Council the daily work involves spending time at the computer. IT-systems were implemented to support and aid the care givers in their work. Around these systems there is a support organization to support the users in using the system. The aim of this thesis is to investigate this organization in terms of how well it works and how successful it is in helping the users. This has been done by investigating the flow of information trough the organization and by focusing at the role of IT-coordinators with responsibility for support, process development, education and statistics.

Background: Since the start of the twenty-first century it has become very important for companies to act in a responsible manner, in guides of CSR. The idea is that companies have more responsibilities than to achieve a higher profit for their shareholders. 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.

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.

This is a thesis presents a differential gear which is found in a tracked vehicle called BvS10. The tracked vehicle is manufactured by BAE Systems Hägglunds AB in Örnsköldsvik, Sweden. The differential gear has a bolted house. The differential meets the requirement specifications, but the problem is that the bolts are sheared off because of the extreme torque that the differential is exposed to resist.Previous report on the differential show pictures of bolts which have been sheared off at the threads. This report is also includes three lists that explain seven different proposals which some are approved and some are not, and the report also presents the force, tensile, and shear stress.In a bolted connection there is both axial tension stress and radial shear stress, which can lead to wear out and broken bolts.

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..

Utvecklingen av informationssystem utförs vanligen med hjälp av en systemutvecklingsmodell där kravhanteringsaktivitetens (Requirements Engineering ? RE-processen) syfte är att samla in och bearbeta kundens alla krav på systemet. Den slutliga produkten av RE-processen är en kravspecifikation där alla kraven gällande exempelvis systemets funktionalitet, syfte etc skall specificeras.Det är inte alltid självklart vilken information som en kravspecifikation bör innehålla då detta dokument kan för både kunden och leverantören ses som ett kvitto på vad som skall utvecklas och hur det skall gå till. Dokumentet skall nämligen fungera som ett underlag för de så kallade implementations- och designaktiviteterna i systemutvecklingsarbetet samt fungera som ett underlag för diskussion och kontrakt mellan leverantör och kund gällande utvecklingen av informationssystemet. Kravspecifikationen bör därför innehålla komplett och förståelig information så att detta dokument uppfyller sina syften.

Intern företagsutbildning via e-learning är ett aktuellt ämne, framförallt eftersom företagen ser det som en chans att bli effektivare och spara pengar. Av de fretagsanpassade utbildningsapplikationer som finns på marknaden idag, är nästan samtliga skapta för att förklara fr användarna (kursdeltagarna) hur saker och ting ska fungera. Deras stora svaghet ligger dock i att förklara och förmedla varför dessa saker fungerar, varpå man riskerar att misslyckas med att förmedla en djupare förståelse och skapa en bättre kunskapsbas. Därför finns det troligen många anställda på företag som har fått lära sig hur allt runt om kring dem fungerar, men inte varför det nu fungerar som det gör. Denna examensrapport redogör för vårt arbete med att ta fram en webbaserad applikationsmodell, utvecklad i Adobe Flash, tilltänkt för utbildning, och som på ett enkelt men effektivt sätt synliggör hur olika typer av företagsflöden fungerar och, framförallt, varför de fungerar på detta sätt.

Process standardization is a topic that has generated a lot of research and literature. At first, the focus was on production; today processes are used in all different kind of business areas.The aim of this study has been to analyze how processes can be applied on development businesses and how IT systems affect the result of the process. To accomplish this, we have asked questions such as what standardization is in a development process? Why are the processes standardized? What difficulties can appear with standardization? And how the IT-systems affect the result of the process?To answer these questions, we have preformed a case study on Saab. Saab is a well know Swedish company who are working with a project called the GMS-project, where they develop processes to cover the whole company´s business areas.The literature gives the reader an understanding of processes and standardization.

The aim of this thesis is to investigate how a valuation model of a Private Equity firm is interpreted into a management control system within the company's different organizational levels. A case study was developed based on the infra-net company Eltel. The management control systems developed by Malmi and Brown (2008)(1) was used to characterize the control systems at each organizational level. The building blocks of this system are planning, cybernetic, reward/compensation, administrative and culture. Miller and O'Learys (2007)(2) theory of mediating instruments and technology roadmaps was applied to analyze the mediating process of the valuation model.
