Managing Positions in a Dynamic Environment - New Technology Impact on Tactel and the Telecom Industry
The Telecom industry is facing a paradigm shift, where the industry is converging with Internet technologies and the market is becoming more sophisticated. This results in more demanding customers, and the need for offering more content and services with a focus on usability for the end-users. The operators are starting to loose both their strong position and revenue in the Telecom industry, due to new technology and the fact that other actors are starting to enter the market, offering new content and services. In the end, the operators have two choices, to become bit-pipe providers, and only focusing on network management, or keeping the control over their networks. The latter would mean that they block other actors who are taking parts of their revenue, e.g.
Virtualiserat datacenter med heterogena kunder för moln eller network-as-a-service-miljö. : Analys resursanvändning vid delad virtualiserings värdmaskin för webbservrar samt videokonferensservrar.
Detta projekt undersöker en praktisk lösning av virtualisering i Ubuntu-server med kvm och virt-manager för användning i en moln- eller Network-as-a-service-miljö. Projektet inkluderar även en jämförelse mellan webbservermjukvaran NginX och Apache2 och en jämförelse mellan videokonferensmjukvaran BigBlueButton och OpenMeetings genom att mäta CPU, Minnes och Nätverksbelastning till de virtuella servrarna vid 1 till 20 uppkopplingar från en klientmaskin.Utifrån projektets resultat rekommenderas Apache2 som webbserver då installationen är enklare och skillnaden i resursanvädning är försummbar och Openmeetings som videokonferesserver då detta alternativ är det mer kompletta..
Från den stora världen till den lilla familjen : En kvalitativ studie om rekrytering, utredning och utbildning av familjehem för ensamkommande barn
This study aims to examine how professionals in the field of foster care works with recruitments, assessment and education of family homes for unaccompanied children. The intention is to find out in case there are specific needs that justify specific approach to ensure that the child's best interests are indicative and satisfied. The survey was conducted based on a qualitative method and empirical data gathered through semi-structured interviews with employees in the social services. The result shows that there is a need for more and specific education for families receiving unaccompanied children. It is motivated by the needs and conditions that are often common for this group.
Minkvalpars beteende i större berikade burar vid olika gruppstorlek :
Farmed mink often perform stereotypic behaviours which is considered to be a sign of reduced welfare. Previous studies have shown that enriched cages can reduce the frequency of performed stereotypies. Most studies on mink in Sweden have been done on adults. The aim of this study was to investigate if larger enriched cages with two or four mink kits reduce stereotypies in mink kits during their growth period in comparison to traditional cages.
In the present study the behaviours of mink kits that were kept in four different treatments at a private mink farm were recorded. Traditional cages with two mink kits were used as a reference and the other treatments consisted of larger cages with shelves with two kits, larger cages with shelves and a plastic cylinder with two kits, and larger cages with shelves with four kits.
Subjektiv och objektiv bedömning av underlag på svenska hopptävlingar på elit- och nationell nivå
Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between regions. In this study, I investigated if landscape structure (e.g. agricultural dominated landscape opposed to forest dominated landscape), forage availability, population density and disturbance (e.g. roads and settlements) affect bark-stripping frequency.
En systemlösning för en framtida fjärrvärmeutbyggnad i Täby : ur Fortum Värmes perspektiv
At the moment in central Täby there are small district heating network operated by
Fortum Heat. The distribution network has an annual heat demand of about 70
GWh, which is supported by the network's two plants, Galten and Farmen.
Täby as a region is rapidly growing and there are grand plans to develop the area.
Estimated market potential for a future district heating expansion in Täby is very
high and as early as in 2007 Täby decided to invest in a large-scale expansion. In
autumn 2009 Täby did a procurement process, known as the ?Täby initiative?, to
find a partner that could implement those expansion plans. To secure a cheap basic
production the partner also need to build a power plant at Hagby recycling center.
Despite high interest during initial state of the process, only one procurement offer
were received and Täby suspended the contract in March the following year.
Överföring av och beräkning med timmätta värden ? från MT2000 till Xpower
New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.
Lågtempererad fjärrvärme i Umeå
People in today?s society are becoming more and more aware of how important it is to use energy as efficiently as possible. This is clearly noticeable by an increase in home produced heat with e.g. solar panels or heat pumps heating systems. These changing customer demands forces district heating technology to be redesigned, which is why there is an ongoing research regarding the next generation of district heating - low temperature district heating (LTDH).
Om att leva i den "snåla världen" : En kvalitativ studie om ensamstående föräldrars och barns upplevelser och strategier i dagens konsumtionssamhälle.
Poverty among children has received a great deal of attention in the media the past few years. The group in which poverty among children has increased most is among single parents; therefore we have chosen to examine this group in this study. The purpose of this study is to take part in single parents and their children?s experiences of living within a very tight budget and the strategies they use. We found it interesting to put this information in relationship to the consumer society we live in today.
Validering som kommunikationsfärdighet till par där kvinnan har vaginism
Vaginism är ett sexuellt problem som förekommer hos kvinnor och som i tidigare utvärderade behandlingar betraktats som kvinnans problem. Forskning inom området vaginism är begränsad och kunskap om parrelationens roll för vidmakthållandet av problematiken och upplevd relationstillfredsställelse saknas. Studiens syfte var att utforma en parbehandling där kommunikationsinterventionen validering lärs ut som färdighet, utforska om det fanns ett intresse för deltagande, samt utvärdera om behandlingen kan påverka relationskvalitet och individuellt välbefinnande. Studien använde en single subject design där ett par fullföljde behandlingen. Resultatet visar ett begränsat intresse för deltagande och ingen större effekt av interventionen.
Seeking Safety som behandling vid PTSD : En single case studie i psykiatrisk öppenvård
Denna single case studie, med multipel baslinjemätning över beteenden, utvärderade huruvida frekvensen traumarelaterade undvikandebeteenden minskade vid 12 sessioners behandling under 6 veckor med Seeking Safety (en behandlingsmanual med copingstrategier för PTSD och samtidigt missbruk), hos patienter med PTSD som inte bedömts lämpliga/redo att direkt börja traumafokuserad KBT. Därutöver utvärderades huruvida behandling med Seeking Safety, kunde öka villigheten att genomgå traumafokuserad KBT. 4 patienter deltog i studien varav 3 fullföljde behandlingen. Resultaten visade en svag tendens i riktning med hypoteserna, men studiens resultat i sin helhet ger ej stöd för behandlingens effekt hos patientgruppen. Av denna studie går ej att utläsa huruvida behandling med Seeking Safety kan leda till minskning av traumarelaterade undvikande-beteenden..

Hur påverkar byggnadsmaterial av stål en induktiv hörslingas fältstyrka samt frekvensgång?
This research analyzed differences in measurements of magnetic field strength and frequency response in five audio induction loops installed in rooms of wooden construction materials and five audio inductive loops installed in rooms of steel reinforced concrete constructions. The inductive loops were installed at floor level and the measurements were made at the listening height of 1.2m. Measurements of background noise, field strength and frequency response were made at fifteen different measurement points across the room. The research measurements showed that there are differences in field strength and frequency response between these two conditions, whether the audio induction loop is installed in a wooden construction or the audio induction loop is installed in a reinforced concrete construction. The results had a significance level of p=0,05..
