Ip-telefoni med Skype som ett alternativ till PSTN för privatanvändare

The project is a practical and theoretical test of IP telephony with Skype in order to form a base for a comparison between IP-Telephony with Skype and the Public Switched Telephony Network (PSTN). PSTN is the common standard that most of us use for telephony today. The objective for the study is to simplify the choice between PSTN and IP-Telephony for the Swedish private customer user group. The project is supposed to answer the following questions. - How easy is it to start using IP-telephony with Skype? - How is the quality of IP-telephony compared to PSTN? - Are all services provided by PSTN available and accessible using the IP-solution? - How are the usability and the availability of support with IP telephony? - Is IP-telephony a cheaper solution and in that case under which circumstances? Within the project a collection of practical and theoretical tests have been performed to be able to form an opinion on the IP-solution in the following areas, installation, function, quality, usability, costs, accessibility and security. In order to study usability, a test group of ten persons have been used to evaluate the usability of the system.

Samband mellan ungdomars föräldra- och kompisrelationer

During adolescence the teenager tries to become an independent individual, something that for many individuals can be experienced as"a hard time". In early childhood the individual was closely connected to the parents, but during adolescence friends and new contacts become more important. Studies in developmental psychology have most often adopted a parent-perspective, which is why a child-perspective is required. The aim of this study is therefore to measure the teenager's relationship with parents and friends and to look for possible correlations between these. As a means of measuring quality in the relationships, the IPPA, the Inventory of Parent and Peer Attachment, was used.

Smaller organizations tend to have more limited amounts of resources at their disposal than larger ones. This can result in difficulties during the implementation process of ISO 9001.


Sömn, depressionssymtom, livskvalitet och Alzheimers sjukdom

Background: Sleep-disturbances in persons with Alzheimer´s disease are prevalent. They are characterized as increased frequency and duration of awakenings, decreased slow-wave sleep, REM-sleep and increase of day-time napping. Depression and lower quality of life are associated with sleep-disturbances. Altogether a significant source of stress for caregivers and an important factor in institutionalization. Non-pharmacological treatment alternatives are rare.Method: Single-case A-B-C design, with non-concurrent multiple baselines, a pilotstudy.Aim: To explore if an educational program on sleep, sleep disturbances and behavioural change directed towards caregivers improved sleep, depression and quality of life in persons with Alzheimer´s disease living at home.

Varför handla svenskt kött? : en konsumentundersökning

The background to the work bases on the consumers view around Swedish and foreign meat products, and how the attitude around the meat products is pursued in the shops. The consumers request high meat quality and security . Many consumers value local produced and ecological meat products but the price is too high. We have done verbal interviews with consumers on three different shops, where we asked questions and had dialogues around Swedish meat products where the consumers have told us their arguments and opinions about Swedish and foreign meat. The result shows that the majority of consumers consider that it is important to know that meat is produce in Sweden.

eWOM-kommunikation på Facebook & Prisjakt : En studie av skillnader i konsumenters uppfattning om eWOM

Purpose ? The purpose of this study is to identify and describe how consumer perceptions regarding information quality, sender credibility and effect of eWOM-communication differ between Facebook and Prisjakt.Approach ? Based on previous research an analytical model was designed. The parts in the model were the aspects of the problem which the present study aimed to examine. An experimental design was applied in which ten students at Örebro University were exposed to a scenario where they took part of eWOM-communication concerning a specific product on Facebook and Prisjakt and then had to answer questions in an interview. The analytical model formed the base of the interview guide used in the interview and the specific product was chosen with help from a focus group.Implication ? The study illustrates that consumers may perceive the quality higher on Prisjakt while the sender credibility can be perceived higher on Facebook.

Kvalitetssäkring av servicelämnare för skogsbrukets arbetsmaskiner : Intervjuer och förslag till utveckling

In this study we have examined the possible quality standards and methods for applications with service workshops in the forest industry. The purpose of the methods presented here was to start the work of standarardising the maintenance service in the industry and be of use for service providers in their quality effort.The methods we used to accomplish the study were interviews and field visits together with a comprehensive literature research. Our results are presented in the form of four solution proposals: a standard based on existing SIS standards for terminology and key indicators, checklists that are filled in by mechanics with customer participation, the construction of a instructions database, and the implementation of the method 5s.We believe our suggestions can help the service providers in the four problem areas that we have identified: long term strategy, documentation, recruitment of competent technicians, and standard procedures in their operations. These improvements will be beneficial for both the service provider and the customer..

Ursprungs- och kvalitetsmärkningens betydelse för konsumentens val av krukväxter : en studie om mervärdet av Mäster Gröns co-branding med Svenskt Sigill

This essay has been made on behalf of the co-operative society Mäster Grön, which is selling ornamental plants to retailers in Sweden. The aim of this study has been to find out what added value Mäster Grön gets from their co-branding with the Swedish Seal of quality. The main topic of discussion was; how much value added does this co-branding give to Mäster Gröns pot plants? Are there differences from a customer point of view in value added between a garden center and a retail store? How much weight does the costumer put on the branding when buying a plant? Does the customer know what the values of Mäster Grön and Swedish Seal of quality mean? Two questions of lesser worth were asked to the consumers about what they thought about the protective plastic around the plant, and if they were interested in getting more information about the origin as well as the method of production of the plant. The study was divided into two parts, one in which customers were observed and one where the customers answered a survey.

Kontrollmodell för kvalitetssäkring av professionella tjänster

För ett serviceföretag är det väsentligt att kunna leverera tjänstekvalitet för att tillfredsställa kunden. Tjänsternas immateriella produktkaraktär gör det emellertid svårt för serviceleverantören i allmänhet och professionella tjänsteleverantörer i synnerhet att säkerställa kvalitet. Syftet med detta arbete är att utveckla en kontrollmodell som kan användas av professionella tjänsteleverantörer som ett hjälpmedel i arbetet att säkra servicekvalitet. Modellen bygger på relevant teori och består av tre kvalitetskategorier ? image, teknisk kvalitet och funktionell kvalitet ? genom vilka 13 kvalitetsdimensioner behandlas.

Simulering av filtrerade skärmfärger

This report present a working model for simulation of what happens to colors displayed on screens when they are observed through optical filters. The results of the model can be used to visually, on one screen, simulate another screen with an applied optical filter. The model can also produce CIE color difference values for the simulated screen colors. The model is data driven and requires spectral measurements for at least the screen to be simulated and the physical filters that will be used. The model is divided into three separate modules or steps where each of the modules can be easily replaced by alternative implementations or solutions.
