Within system development users have rarely been involved or received much attention during the development. Most of the times, the primary focus within system development lies on insuring functionality, rather than making the system usable. The literature specifies that a non user-centered approach can contribute to a product with low usability, which can lead to an ineffective and unsatisfactory experience for the end users.The purpose of this thesis is to begin an investigation to see if the use of non user-oriented system development methods is a possible cause of low usability in the final system.To achieve the purpose of this thesis, we have conducted a case study. Within the case study we examined the usability of a time reporting system. The case study included seven minor studies; an investigation concerning the development of the system, an expert evaluation of the system, interviews and observations of users, developed paper prototypes and executable prototypes, both which user testing was performed on.The result of this study shows that by working with user-entered methods, the usability in the time reporting system increased after the design had been revised.

In industrial control systems PID-control remains the prevalent strategy, also for processes that would benefit from model based control. The purpose of this thesis is to evaluate whether model based control can be readily implemented in an industrial control system. To this end a simulated surge tank with a simulated industrial control system is studied. For evaluation two scenarios with specified objectives are selected.Following a review of LQR and versions of MPC, Predictive Functional Control (PFC) is considered the most suitable for implementation. PFC is a form of MPC developed with industrial applications in mind and therefore has several advantages for implementation in an industrial control system.

The mainpart of this thesis is about the developing of a new analysis tool to be used in Zenicor Medical Systems AB ECG-system. The primary task of the system is to simplify the ECG survey for patients who suffers from different kinds of arrythmias, for example heart fibrillation. With this system is it possible for the patients to do their ECG survey by them self at home and then send the signal with their telephone or mobilphone to a server. The equipment used to do the survey is not bigger than you can have it in a pocket and this results in a bigger flexibility for the patient. A doctor can connect to the server and analys the ECG-curve and follow up the patients condition..

The main goal was to develop a reservation system and to make it work with Dreamgallery, to develop a demonstration version of the system. The thesis describes the approach for developing an easy-to-use and customisable program and interface for making reservations. How this is inserted into an existing program in a suitable way.

I föreliggande studie har det undersökts vad som påverkat linjechefer att fullfölja sina förändrade arbetsförhållanden. Förändringarna är ett resultat efter att en större omorganisation har genomförts, en så kallad Human Resource Transformation. Studien baserades på Icek Ajzens Theory of planned behavior, vars utgångspunkt är individens intention att utföra ett tänkt beteende. Det antogs, utifrån Ajzen (1991), att de tre faktorerna, attityd, subjektiv norm och upplevd beteendekontroll var av betydelse för intentionen. Sammanlagt svarade 42 linjechefer från Skatteverket på en enkät om attityder, subjektiva normer och upplevd beteendekontroll gentemot de nya arbetsuppgifterna.

At the plant of Sandvik do Brasil in São Paulo there is a need for improving the transport of inserts between the plant building and the stock building. The idea is to install a system with an Automated Guided Vehicle (AGV) to take care of this transportation. The purpose of this report is to present which demands there are on the system and to find the best solution according to the demands.To conclude this work a study was made of the plant and the AGV technology was examined. Several providers of AGV solutions were contacted to get information about prices and detailed solutions.The conclusion was that the most suitable system for this application is a small unit load vehicle using inductive wire as guiding system..

Summary Title: Taxes and Human Capital as Determinants of Foreign Direct Investment in EU: The role of Most Favoured Nation treatmentAuthor: Andreas HelmerssonSupervisors: Cecilé Brokelind and Rikard LarssonProblem discussion and problem Formulation: The recent year?s rapid increase in foreign direct investment (FDI) is a clear indication of increasing globalisation. In order to stay competitive companies must take advantage of talented people, new technology and new markets around the world. Not only companies but also countries and regions, such as EU, need to take advantage of globalisation and the advantages that come with the increase in FDI around the world. Studies have shown that FDI does not only make companies more competitive but it also stimulates the economic growth of the region where the FDI takes place.

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 samhällsrelaterade redovisningen har utvecklats under de senaste åren och fått en allt större betydelse för företagen och dess intressenter. Att utvecklingen går mot mer kunskapsintensiva verksamheter borde öka betydelsen av personalredovisning, vilken är en del av den samhällsrelaterade redovisningen. Det bör ligga i företagens intresse att redovisa sin personalrelaterade information med tanke på att det är en allt viktigare tillgång. Med anledning av att det endast finns ett fåtal regler för hur personalen skall redovisas, väljer företagen det sätt som passar repektive företag bäst. Syftet med undersökningen är att klargöra för i vilken omfattning svenska börsnoterade företag redovisar sin personalrelaterade information, om det skiljer sig mellan företagen beroende av branschtillhörighet, storlek eller någon annan faktor.

This thesis work resulted in a template for how the thermal spray process can be controlled through robot programs. The robots today and their programs need to be replaced, therefore a new structure which can be matched with the new robot systems is needed. The work is limited to only concern structured programming on the new robots on Thermal Spray Centre (TC) with the programming language Rapid. The basic data for the program was retrieved from interviews with concerned personnel at TC, from studies on process parameters for thermal spray and from existing specifications at Volvo Aero Corporation (VAC). The thesis work briefly describes the process thermal spray and the four methods used at VAC.

This thesis discusses the existential consequences for the human being in creatio ex nihilo, where the main subjects of discussion are contingency, freedom and identity. The starting-point of the discussion lies in the presentation of the history of the doctrine of creation, especially the doctrine of creatio ex nihilo. Once the historical and philosophical importance of the doctrine of creation is clear, the anthropological and theological consequences are obvious; creation is contingent and at the same time deeply dependent upon God. The contingency of creation may bring a sense of non-necessity among people, and therefore it makes the question of human freedom and identity in the doctrine of creation utterly important..

The main focus for this essay is to describe the relationship between human and nature through a material investigation that takes its shape through sculpture. With the help of a fairytale-like story the reader can share the creation of the sculpture and how my thoughts flow through the process that will result in an exam project. Rooted in earlier projects I discuss the crash between civilization and the wilderness as well as talking about the likeness of the creative process and child play. I also discuss the body's place in the forest and the loneliness that we humans created that has cut us off from the rest of the creatures and plants in the forest. My aim is that in the final piece I will create a fiction place where these can be joined together again.

Linjäriseringar av olinjära system är mycket relevanta eftersom det finns en i förhållandevis enkel och omfattande matematisk teori kring linjära system, till skillnad från allmänna olinjära system.För vissa olinjära system är det svårt eller inte ens möjligt att genomföra en analytisk linjärisering.Orsakerna till detta kan vara hög komplexitet av systemet eller avsaknaden av ett analytiskt uttryck.Numerisk analys kan vara en lösning på detta problem.I detta examensarbete används framåtdifferens och centraldifferens för att genomföra de derivata-approximationersom behövs för att genomföra en numerisk linjärisering av ett olinjärt system.Rapporten behandlar även vad som sker då det är dålig upplösning på den indata som används när man genomför enlinjärisering, vad som händer med heltal och binära signaler om de ingår i ett system som linjäriseras ocheffekten av att ha olika samplingstider för olika delmoduler i ett system som linjäriseras.Slutligen undersöks numerisk bilinjärisering av ett system på bilinjär form och en jämförelse mellan analytisk linjärisering och bilinjärisering görs..

The aim of this study is to find out if, and in what way the Maasai pastoralists affect the spotted hyena (Crocuta crocuta) through Bomas (Maasai settlement) and keeping of livestock. The study was carried out in the Maasai Mara National Reserve and the adjoining group ranch, Koyake GR, in South-western Kenya.Data was assembled through transect driving, with instantaneous scan sample during two seasons, December 2003 and May-June 2004. Study area contained 12 bomas with three different type of transects each: T1 (0.5 km from boma), T2 (3 km from boma) and T3 (5.5 km from boma), to create a gradual decline in human and livestock impact. Results show that there are differences in the hyena's utilisation of transect type during the day and during the night. The spotted hyena tend to avoid transects close to the boma during the day time, but go there during the night time.
