Design av Kalmanfilter för signalbehandling av antennsvar från riktade mikrovågsantenner

The main purpose of this bachelor thesis is to create a product in the form of a database that can be used for cost estimates of equipment within bio refineries. Through interviews and literature searches the key components and their costs were identified. The database was constructed in Microsoft Excel with different tabs for different categories of components; these tabs are further divided into three parts: one part with costs, one part with calculations and an information part. Most of the part with costs contains the expenses found in scientific papers during the literature study, the calculating part converts different capacities according to user preferences and the currency to euro (?) from 2010 and the information part consists of references and information about what is included in the cost.The database is a good tool for making cost estimates for bio refineries.

Bibliotekarien och en ny elektronisk referenstjänst Projektet och chattreferenstjänsten Tala direkt med en bibliotekarie

This master thesis is a study of a new electronic library reference service-project called Speak instantly to a librarian and the purpose of the thesis is to investigate a new electronic reference service and how the librarians who work with it experience it. This should be seen from an informational society point of view. The study is conducted from two questions: - What needs do the libraries have and how do they argue for the project and the chat-reference service Speak instantly to a librarian? - How do the librarians experience the personal work situation in the new reference service, and its use of chat technology? Together with interviews of a selected group of librarians from the public libraries of Göteborg, Malmö, Nacka and Stockholm, this thesis includes aspects such as the theory of the informational society by Manuel Castells, as well as literary studies of the history of library reference, the development of electronic reference service and the virtual library, and the background and the beginning of the studied project Speak instantly to a librarian. The thesis also contains an overlook of other similar library projects in the United States of America.

CFD simulering av en fyrtakts Otto motorcykel motor

This thesis deals with the numerical 3D simulation of a four stroke, spark-ignited, internalcombustion engine, which is mounted on a high performance motorcycle. The work, carried outin collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of theintake, compression and expansion stroke, including combustion simulation, using an opensource CFD code.Simulation of internal combustion engines offers a great challenge in the field of CFD research.Moving boundaries of the solution domain, caused by the motion of the piston and valves, leadsto deformation of the computational grid, with decreasing quality of the solution as result. Basedon this, a previously developed mesh motion strategy was employed where a number of meshesare used to cover the whole simulation cycle. Within each mesh interval the internal cell pointsof the mesh are moved to account for the boundary motion of the piston and valves. This strategywas previously applied to simplified geometries as well as real engine geometries.

Kostnadskalkylering på en förpackningsavdelning

This degree project is based on identifying and allocation of costs in a packaging section at Electrolux Distriparts in Torsvik.The purpose of this thesis is to identify the costs that emerge when packaging different articles and show how the costs are allocated. The report also contains improvement suggestions about how the company can use the current computer system more efficient.The methods that have been used in order to approach the problem and the collection of information have mainly been literature study, interviews and observation.The work started with answering the questions; which expenditure cost and direct cost exist in the section, how can they be allocated, if improvement can be done and how the flow of information is supposed to happen.In order to answer the questions we used our former experience and the knowledge we achieved by reading literature, interview relevant persons in the company and observations carried out in the section.Through our studies, we came up with an Excel file, which is the groundwork for a template that can be used by the company in different occasions depending on the situation and need. It is important to remember to modify the template if the presumptions change. In the template, we have identified the different kind of costs that emerge when packaging different articles and we have also allocated the costs. In addition formulas and estimations that are necessary for the cost calculation are presented.The work consisted in making the groundwork for a template.

Kartläggning och utvärdering av informationssäkerhet i en kommun

Informationssäkerhet har idag en viktig roll inom organisationer. Det finns undersökningar som visar på att attacker ökar för varje år. För säkerhetskritiska organisationer som kommuner är det därför viktigt att man har uppdaterad säkerhetsteknik, då man lätt kan falla efter i det snabbt utvecklande ämnet informationsteknik. Uppgiften som gavs av Nexus AB var att kartlägga och utvärdera en kommuns informationssäkerhet. De ville få reda på hur det egentligen låg till med informationssäkerheten i en Stockholmskommun.

Utformning av kylkanaler och spånrum på superturbofräsar

This thesis describes how the chip space and coolant channels are designed in today?s mills, the ideas behind the design and what is considered to be the best method of cooling. It contains ideas on how the chip space can be simplified. It contains several concepts on how the cooling could be designed for better efficiency and manufacturability. There are also suggestions on how the cooling could be stopped when the cutter isn?t cutting.

Syftet med arbetet var att undersöka pedagogernas inställning till lek i skolans lägre årskurser. Vidare att belysa lekens betydelse för den kognitiva utveckling och hur pedagogerna använder leken i sitt dagliga arbete. Metodern är en kvalitativ, halvstrukturerad forskningsintervju med hermeneutisk inriktning och bygger på intervjuer med sex pedagoger. Jag redovisar intervjuerna i fyra olika teman, som kom fram under analysen av intervjuerna. Sammanfattningsvis pekar resultaten av min undersökning på att samtliga pedagoger är positit inställda till att lek och kopplar leken till den kognitiva utvecklingen..

Behavior Cards - ett programmeringsverktyg för barn

This thesis presents the work of developing and testing a programming tool specially designed for children. The purpose of this tool is to make children capable of creating visual simulations and games that consist of actors interacting in a virtual world. The name of the programming tool is Behavior Cards, which comes from the fact that actors are programmed by giving them cards representing different kinds of behaviors. Behaviors are to some extent pre-programmed and can include general events specifying how the actors should act in different situations, in contrast to specifying every possible situation that can occur. The idea is that Behavior Cards should be easier to use than a more traditional text based programming tool, but it should also be expressive within the domain of visual games.

A targeted evaluation of OpenEye?s methods for virtual ligand screens and docking

The process of drug discovery is very slow and expensive. There is a need for reliable in silico methods; however the performance of these methods differs.This work presents a targeted study on how the drug discovery methods used in OpenEye?s tools ROCS, EON and FRED perform on targets with small ligands. It was examined if 12 compounds (markers) somewhat similar to AMP could be detected by ROCS in a random data set comprised of 1000 compounds. It was also examined if EON could find any electrostatic similarities between the queries and the markers.

Ledare & team utan rätt förutsättningar kan aldrig nå maximal framgång : En studie om tre olika produktionsverksamheter inom Volvo Group

This thesis has been conducted at Volvo Bussar ABunder a period of ten weeks. Within the organizationVolvo, the work is conducted with leaders and teamson every level; from production to top management.They have three tasks, besides executing their dailywork, they are expected to actively work on improvingtheir individual work as well as themselves as persons.The two latter are future value adding activities for theorganization. When doing so, however, it has beennoticed that they often lose the grasp of their dailywork. The question that consequently arises is whythis happens. Is it because of lack of time or it isbecause the co-workers do not have the competenceand simply do not know how they are to execute thethree tasks? Or, is it because the motivation to executethe three tasks is not enough? With this in regard, thestatement of issues for this bachelor thesis were thefollowing: how can the conditions for leaders and theteam be improved, in order for them to execute thesethree tasks.To find out why the execution of these threeassigments did not always succeed, the decision wastaken to conduct a survey and interview study in reallife and at the plants.
