Efficient Frequency Grouping Algorithms for iDEN
This Master?s Thesis deals with a special problem that may be of importance when planning a frequency hopping mobile communication network. In normal cases the Frequency Assignment Problem is solved, in order to plan the use of frequencies in a network. The special case discussed in this thesis occurs when the network operator requires that the frequencies must be arranged into groups. In this case the Frequency Assignment Problem must be solved with respect to the groups, i.e.

Competence Portals are software tools that are intended to make it easier for persons that have had no previous contact to find and contact each other. The portals can address areas ranging from finding an expert within an organisation to the marketing of the competence of a region or a research centre to other organisations. The purpose of the thesis is to examine the necessity of Competence Portals in research-intensive organisations. Important characteristics of the information in such portals have been identified and used as a basis for recommendations regarding how Competence Portals could be designed. Furthermore, the thesis focuses on the task of finding a source of knowledge within an organisation.
Social Software Roadmap : Implementering av sociala verktyg internt i organisationer
Today more and more companies are looking out to adopt a new generation intranet, a social intranet where all employees can engage to express themselves and share information. There are large expectations on these new services, which have the opportunity to create high business value if used actively and qualitatively. However, there is a large challenge in knowing how to best implement these services in an organization in order to achieve this. This paper has investigated how an implementation should be made by defining obstacles for the implementation and adoption, discussing how they could be overcome, investigating what incentives could be used to foster usage and finding common success factors for an implementation.By a qualitative research method, consisting of five case studies and two focus area interviews we found a number of steps that must be followed for an implementation to be successful. First the conditions of the organization must be investigated in order to see whether or not social tools are suitable.

Att spara eller inte spara? : En kvantitativ enkätstudie av informationslagringssystem för vetenskapliga artiklar
Abstract PurposeThis thesis aims to focus on how master students administer scholarly articles after they have found them. The purpose of the study is to detect how and to what extent people administer their articles from a personal information management-perspective (PIM).MethodTo answer the research questions, a web-based questionnaire survey was distributed which was announced to around 2,000 master students from different universities in Sweden. Most of the items in the survey focused on individual storage methods. The respondents were asked to rate the frequency of their different information administration behaviors on a seven level Likert-type-scale. Subsequently, items concerning specific information administration behaviors were posed, followed by questions on the respondent's sociodemographic status.

Hazel- Ett mjukvarusystem för automatisk och optimal schemaläggning
This report documents the development of a software system for automaticscheduling called Hazel. This system is comprised of a server where an automaticscheduler has been implemented, as well as a web and mobile applicationthat allows users to interact with the system. The scheduler hasbeen developed with the functional programming language Haskell and usesa SAT-solver.Manual scheduling has long been the bane of managers everywhere, asmatching the needs of the employer with those of the employee is often adifficult and time-consuming task. There already exists several automaticschedulers that attempt to solve this problem. The issue with said schedulersis that thay tend to be expensive, or developed to only fulfill the needsof a particular organisation.

Vikten av gemensamt avslut vid datorförmedlad kommunikation i en lärandemiljö : En studie om att reducera det sociotekniska glappet vid flexibel undervisning via videokonferens
I rapporten undersöks problemställningen ?Hur kan teorin om Gemensam grund och specifikt ?gemensamt avslut? bidra till en ökad förståelse för betydelsen av social interaktion i flexibel undervisning via datorförmedlad kommunikation?? i en fallstudie med fokus på videokonferenssystem vilka används i lärandemiljöer. Resultaten som framkom tydliggjorde att då ett sociotekniskt glapp uppstår tvingas studenterna att skapa alternativa strategier för att kunna uppnå just det här gemensamma avslutet. Därmed uppvisar också resultaten att drivkraften att uppnå gemensamt avslut inte endast är stark vid kommunikation som sker ansikte mot ansikte utan även vid datorförmedlad kommunikation. Fallstudiens resultat kan därmed ses som ett bidrag till grundforskningen i det att betydelsen av att uppnå gemensamt avslut vid datorförmedlad kommunikation uppvisas, vilket också förstärker betydelsen av Clarks (1996) teori om gemensam grund.

Datasäkerhet för hemdatorer. Brandväggar för privatpersoner.
I arbetet med denna uppsats, har vi undersökt om brandväggar håller vad de
lovar och om de i så fall ger full datasäkerhet. Vårt syfte är att, ur
hemmaanvändarens perspektiv undersöka vad datasäkerhet innebär, hur hotbilden
vid Internet-användning i hemmet ser ut och vad personliga brandväggar kan
erbjuda för skydd. För att ta reda på detta gjorde vi följande
frågeställningar:
Vad är/innebär datasäkerhet?
Vad skyddar en brandvägg mot?
Vad skyddar brandväggen inte mot?
För att besvara våra frågor har vi använt oss av tre metoder; litteraturstudie,
test av tre stycken brandväggar och intervjuer med två personer med kunskaper
inom datasäkerhet.
Vi har med hjälp av metoderna kommit fram till att beroende på att en av de tre
undersökta brandväggarna släppte igenom en trojan, trots att denna brandvägg
sade sig stoppa sådana, så håller inte alla brandväggar vad de lovar. På grund
av många användares omedvetenhet om farorna eller brist på insikt om sin egen
utsatthet men även på grund av att hotbilden är så föränderlig, är det svårt,
för att inte säga omöjligt att uppnå full datasäkerhet.
Mätningar av statiska och dynamiska egenskaper för bakaxel.
To design new and high tech products the engineers rely more and more on computer based simulations to investigate the properties and behavior for a component or system.To verify these computer based simulations the dynamic properties for the components of the drivetrain needs to be verified. Therefore measurements of the stiffness and vibrations for the rear axle has been performed. This report show how the measurements has been implemented and evaluated, along with some interesting results for the rear axles properties.The static stiffness for the drive shaft along with the axle-gear has been determined. It is found that the stiffness for the whole rear axle is near the stiffness for the drive shaft, which means that the drive shaft becomes the dominant component of the system and affects the rear axle stiffness the most. The measured stiffness of the driveshaft is close to its theoretical stiffness.The stiffness for solely the hypoid-gear have been calculated using the stiffness for the rear axle and driveshaft, and thus has a range for the stiffness of the hypoid gear been determined.The backlash for the whole rear axle and for some individual components has been determined, where the backlash between pinion and crown-wheel has negligible impact on the total backlash.Measurements of the crown-wheel and pinion movements have been conducted, where the direction of movement is consistent with the theoretical direction of the forces.The vibration measurements show that the vibrations are more severe at certain rotational speeds.
