Utökade tester enligt IEEE std 1149.1-2001 för Main Switch Board
Kravet på detta examensarbete var att utveckla tester för en produkt i prototypstadiet hos Ericsson i Katrineholm. Dessa tester ska framförallt användas som verktyg vid felsökning och utvecklas på kretskortsnivå. Detta innebär test för att hitta processrelaterade fel som t.ex. felaktiga lödningar. Arbetet började med att studera den tekniska bakgrunden.
Signalanalys med ATLAS
On Ericsson Ltd in Borås a wireless communication system called MINI-LINK? is produced. In order to sell their product with the best possible quality guaranty, there is a signal processing circuit called ATLAS implemented in the system. This circuit would eventually be useful in the production and for the repairs of the radio units. Our commission was to examine the possibility for this use.
Development and evaluation of environmental enrichment for captive Humboldt penguins
Environmental enrichment is of high importance for zoos. Borås zoo asked SLU (Swedish University of Agricultural Sciences) for a student to perform a bachelor thesis for them. The task was to develop and evaluate environmental enrichment for their Humboldt penguins. A structure was made, consisting of a sinking skeleton with a floating bridge attached to it. It was presented in an area of the pool that the keepers had experienced that the penguins did not use to any extent.
Lämna inte slumpen åt slumpen - En studie om hylloptimering i den digitala butiken
This paper examines the impact of conscious shelf management on online grocery stores. An S-O-R framework is used to unveil if some established shelf management techniques from physical stores are applicable in an online context. We also explain some of the cognitive processes customers experience as they get exposed to online buying situations. A main study with two data sources is conducted: one quantitative website experiment with 168 participants who got exposed to five different organisation patterns within five different categories; and one more qualitative eye tracking experiment with 20 participants. The results indicate that a disorganised product page evokes not only different scan paths and cognitive patterns but also generates higher sales.
Identitetsverifiering via tangentbordsstatistik
One important issue faced by companies is to secure their information and resources from intrusions. For accessing a resource almost every system uses the approach of assigning a unique username and a password to all legitimate users. This approach has a major drawback. If an intruder gets the above information then he can become a big threat for the company and its resources. To strengthen the computer security there are several biometric methods for identity verification which are based on the human body?s unique characteristics and behavior including fingerprints, face recognition, retina scan and signatures.
Förenklad felinformation på trafikinformationsutrustning
This thesis lays the foundation of the future routines of effective error repotring fortraffic devices in the raiway sector.If a device, for example a timetable display, stops working it is vital that the device isfixed as fast as possible so that the travelers dont miss any important information.The methods that are used today are old and not very effective. It can take time forthe repairmen to find the right device or locating the broken component. At the sametime he is supposed to maintain telephone contact with central control throughoutthe whole session.The need for a new, more effective, system is vital to make the whole repair pfocessmore effective and let the repairmen work without having to contact the centralcontrol by phone.I started this work by examining the possibilities of assigning every object with aunique identifier (ID tag) that could be accessed by a manual scan device. The ideawas that the ID tag could holw information about the object and be obtained byscanning the ID and get the information presented on a mobile device.The work also included building a internet application that enabled the reader to seeand change the information on the ID tag.The result was a database that stored information of different objects which could beobtained by scanning the ID tag and presented by a internet application..
Ompositionering av varumärken : en strategisk fråga
Background: Brand strategy tends to become an important management issue. It is therefore interesting to reach a greater understanding about how companies work to make their existing brands stronger. The purpose of a brand is to influence the customers? view of the brand image. The literature is insufficient concerning how leaders handle the process of repositioning a brand, in order to change the brand image.
Vikten av säkra nätverk
The purpose of this thesis is to show how to use vulnerability testing to identify and search for security flaws in networks of computers. The goal is partly to give a casual description of different types of methods of vulnerability testing and partly to present the method and results from a vulnerability test. A document containing the results of the vulnerability test will be handed over and a solution to the found high risk vulnerabilities. The goal is also to carry out and present this work as a form of a scholarly work.The problem was to show how to perform vulnerability tests and identify vulnerabilities in the organization's network and systems. Programs would be run under controlled circumstances in a way that they did not burden the network.
Sensorfusion för undervattensrobot i kärnteknisk miljö med Kalman filtrering
WesDyne TRC AB is a fully owned subsidiary of the global WestinghouseElectric Corporation. WesDyne is a world leader in non-invasive methods for theinspection of nuclear power plants. One of the inspection platforms used to scanfor defects in and around the welds in the reactor vessel is called the T-crawler.The T-crawler operates under water in a radioactive environment by stepping onthe vessel (reactor tank) inner wall using suction cups. The environment is harshand many traditional positioning sensors are not suitable for implementation. Thisthesis investigates the possibility to use a gyroscope and a pressure sensor tocreate an alternative and independent positioning system.

Opportunities to a full range of new services are given through barcode recognition in a Symbian OS based device. Therefore the purpose of this degree project was to create an application which would contribute to a future solution aimed at shopping where the cell phone constitutes a reader of items? identification numbers.
Tidsbudget Przewalskis vildhäst (Equus ferus przewalskii) på Nordens Ark
During the winter 2011 Isaksson and Andersson did a time budget study on Nordens Ark?s Przewalskis horses during daytime when there were visitors and caretakers in the park. This time budget study was made during daytime and when there were no visitors or caretakers in the park. The horses where observed in the morning (5.30-6.30 am) and in the evening (5.45-6.45 pm) during four days. In addition to a time budget, the horses? positions in the enclosure were registered.
Slutna kontanthanteringssystem - en investeringsbedömning för Gekås Ullared AB
Med utgångspunkt i de stora mängder kontanter som hanteras i flera instanser på Gekåsvarje dag valdes uppsatsens ämne. Syftet var att bedöma effekterna av en eventuellinvestering i ett slutet kontanthanteringssystem, för att sedan lämna rekommendationertill företagets ledning.Undersökningen är gjord som en deskriptiv fallstudie med Gekås i centrum. Företagetoch dess behov har utvärderats med hjälp av egna erfarenheter och information från såväl ledning som anställda på kassakontor och i kassan. Kunskap om tillgängliga kontanthanteringssystemhar fåtts från tillverkare, säljare och användare, och för att slutakedjan konsulterades företagets värdetransportör.De vinster med ett slutet kontanthanteringssystem som uppmärksammats är framförallteffektivitetsvinster i form av stora tidsbesparingar vid kontanthanteringen och merrörlig personal, samt en säkrare och mer trivsam arbetsmiljö i kassan. De största kostnadsbesparingarnaskulle uppnås genom att vissa moment hos kassapersonal, på kassakontoretoch för den kassaansvarige försvinner.
Jämförelse av programvaror för konstruktion i råa punktmoln
Laser scanning is a method of surveying that has evolved rapidly in recentyears. The technique is based on a laser scanner set up, which can document a structureusing pulsed laser beams. Each time the laser hits a surface it is partly reflectedback to the scanner that stores the point. By using strategically placed targets, storedpoints from different scans can be merged into a point cloud. A point cloud is avisualization of the scanned object with a very high accuracy.

Impact by bomas on the distribution of spotted hyena (Crocuta crocuta) in the Mara Region, Kenya
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.
