Hallå, är någon där? : En studie om informationsnyttjande mellan handelskanaler
Syftet med denna studie har varit att undersöka hur företag samlar in och utnyttjar kundinformation mellan försäljningskanalerna. Men även att utreda motiven bakom att bli en multikanalåterförsäljare samt produkttypens roll i beslutet. En kvalitativ fallstudie med semistrukturerade intervjuer har tillämpats, där fyra företag och en expert deltagit. Studien har visat att information om kunden har varit värdefull och har använts emellan handelskanaler för att anpassa butikens sortimentsmix, skapa välgrundade kampanjer och styra kunder till butik. De mindre företagen, sett till omsättning, har haft mer användning av kundinformation vid beslutet att öppna fysiska butiker än de större.
Kontrollerad vokabulär eller naturligt språk? En empirisk studie.
The question whether controlled vocabulary or natural language free-text terms is the most effective search strategy has occupied researchers in LIS for many decades. This Masters thesis is an empirical study which aims to compare these two search strategies in LISA Library and Information Science Abstracts, an online bibliographic database. 22 topics from the discipline of Library and Information Science were constructed and out of each topic one query for each search strategy was formed. Queries in natural language were formed with terms from different sources, for example dictionaries, while queries in controlled vocabulary were built with terms from LISAs electronic thesaurus. The measures used in this study were precision, relative recall pooling method and overlap.
Närvarodetektor med IR och ultraljud
En närvarodetektor i form av en IR-detektor uppfyllde inte de önskade kraven och Eluw Electronic AB hade planer på att utveckla produkten vidare. IR-detektorn registrerar endast rörelse på en person vilket inte alltid är tillräckligt i företagets anläggningar. En person som inte är i rörelse måste också detekteras för att upprätthålla säkerheten runt en specifik anläggning. Företaget efterfrågade en närvarodetektor som klarade båda dessa detekteringar. Ett examensarbete på Luleå tekniska universitet löste uppgiften och en väl fungerande närvarodetektor med IR och ultraljud har utvecklats.
Rening av avloppsvatten efter skärprocess
ABB I-R Waterjet Systems combines the robotics and motion expertise of ABB Flexible Automation with high-pressure intensifier/pumping technology from Ingersoll-Rand to provide and continue to develop innovative waterjet cutting systems for global markets. The purpose of this assignment is to develop a process water purifier. The purifier should be applicable as an option to ABB I-R?s production cell Cutting-Box. At first hand the process water should be purified well enough to let out in the municipal sewage system, but the ultimate solution is purifying the process water to the range that recycling is possible.
Utveckling av biopsiinstrument : Instrumenthållare för skruvnålsbiopsi
This Master Thesis has been carried out in cooperation with Ursus Medical AB (URSUS) which markets, assembles and sells the Rotex Screw Needle Biopsy Instrument ®. The instrument is delivered with an instrument holder. Customers had expressed dissatisfaction over that they needed to use two hands during a biopsy procedure, which resulted in a project to develop a new instrument holder.The project aim was to create concepts for how the new instrument holder should be designed, with focus on the mechanics. The new instrument holder would build on the existing basic principle that the screw needle and the cannula were screwed into the tissue. The thesis work would result in a technical solution and a functional prototype of the chosen concept.To achieve this, a generic product development processes were used and began with a comprehensive literature review.
Nollavräkning av entreprenadprojekt: Teoretisk grund och praktisk betydelse
The purpose of this study is to investigate the method called zero recognition that is used in accounting for construction contracts when the outcome is uncertain. When this is the case it is hard to make the necessary estimates needed for the percentage of completion method to be used. Both the meaning of the method from an accounting perspective and the practical importance and purpose of the method is investigated. The method used for this study is the qualitative one and the deductive model is used to relate the theory with the empirical research. The theoretical background consists of accounting theory and theories about individuals, companies and markets.
Samkörning av databaser-Är lagen ett hinder?
Title:Comparison of databases ? Is the law an obstacle?Authors:Alexander Ankarberg, Applied Information Science.Tutors:Lars- Eric LjungProblem: Cross running databases is getting more and more significant during the development of the information flow. There are huge benefits if we start to use the technique that already exists. The law is today an obstacle, so what would happen if the law wasn?t so stern.
Buntning av grot med lastbilsmonterad utrustning :
During the transportation of logging residues (LR) the material´s low density is a problem that results in low use of pay-load capacity. Comminution or compression of LR are possible methods to increase pay-loads. In the present thesis studied a bundling machine which was mounted on a truck chassis, and the subsequent transport and crushing. The truck bundler created bundles that were larger and longer than other bundling equipment on the market. The objectives were to determine the total time consumption and its allocation over work element and machinery, to measure dry matter (DM) content of green and brown LR-bundles.
Interventioner som reducerar oro inför och under anestesi hos vuxna patienter
BackgroundResearch shows that the majority of patients feel anxiety before and during anesthesia. It has been shown in several studies that preoperative anxiety may cause adverse effects in the postoperative course. Nurse anesthetists have a key role in creating a safe environment and the opportunity to use different interventions to reduce the degree of anxiety.AimThe aim of the study was to examine which interventions may reduce anxiety in adult patients before and during both general, local and regional anesthesia.DesignSystematic literature review with a quantitative approach.ResultsSeveral studies indicate that gabapentin and pregabalin can reduce anxiety before and during anesthesia. The anxiety reducing effect appeared to be dose dependent. The naturopathic drugs Citrus aurantium blossom and Passiflora incarnata Linneaus were found to reduce anxiety before anesthesia.
Säkerhet och integritet i närfältskommunikation
Context. In today?s society we use smart cards in many areas, NFC is a smart
card technology that allows contactless interaction between a reader and the
tag, the tag is often in the form of a card. NFC can be used for various
payment methods or as access card to a building which makes life easier. In
previous studies, the technique has proven to be weak to attacks using an NFC
reader connected to a computer.
Nyutveckling av hopfällbar kvistsåg
This Master Thesis has been carried out as a new product development project in collaborationwith G-Man Tools AB located in Edsbyn. The purpose of the project was to construct a newpruning saw there the blade is integrateble in the handle, thus a foldable pruning saw.The work has been performed on the occasion of G-Man Tools AB wanted to improve theirproduct range by creating a saw that complement their range of quality saws. They have a similarproduct today, but they do not manufacture this product by them selves and it is not directlytargeted against garden use, which is a disadvantage when it is one of their major markets.Even though almost the entire chain from the requirements of the users to drawings has beentaken into consideration, emphasizes has been put on generating ideas. However the first thingthat was carried out was to establish a productspecifikation from interviews with users and thecompany?s experience.

Integrationsprojekt på två bibliotek: mångfald, möten och möjligheter
Integration projects at two libraries: multiculture, meetings and possibilities takes its start in the fact that Sweden is populated with people from many different nations. The libraries have a unique possibility to arrange integration projects as a supplier of culture and information. This case study focuses on two integration projects arranged by two libraries; the library of Jönköping with the project Brobyggarbiblioteken, and the library of Kortedala which was involved in the project Ordbron. My purpose is to find out how these two libraries chose to work with integration, migrants and multiculture. The aim is to examine if the library could function as a passway to the Swedish society, and to find out if the library can facilitate for migrants to maintain contact with their native country.
Pliktleverans under förändring: en diskursanalys av E-pliktutredningen samt diskussion kring dokumentbegrepp som uttrycks däri.
Sweden has a long tradition of collecting documents by way of a process of legal deposit of copies. Its aim is to ensure the availability of material for research, cultural preservation and citizens? right to free information. New forms of publications, made possible by technical advances, are not accommodated in the traditional deposit submission criteria. Certain information accordingly risks being lost.
