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.

Utvärdering av den upplevda användbarheten hos CySeMoL och EAAT med hjälp av ramverk för ändamålet och ISO/IEC 25010:2011

This report describes a study aimed at uncovering flaws and finding potential improvements from when the modelling tool EAAT is used in conjunction with the modelling language CySeMoL. The study was performed by developing a framework and applying it on CySeMoL and EAAT in real life context networks.The framework was developed in order to increase the number of flaws uncovered as well as gather potential improvements to both EAAT and CySeMoL. The basis of the framework is a modified version of the Quality in use model from ISO/IEC 25010:2011 standard. Upon the characteristics and sub characteristics of this modified model different values for measuring usability where attached. The purpose of these values is to measure usability from the perspectives of both creating and interpreting models.

Bibliotekskatalogers användarvänlighet : en usabilitystudie av Umeå Universitetsbiblioteks katalog Album

The purpose of this thesis is to examine the usability of the Umeå University library catalogue Album. The aim is to evaluate the catalogue in order to establish if there are any problems that could be solved by modifying the catalogue. The following questions are answered: How should a good catalogue be designed? Which problems are common when using a library catalogue? Is Album user friendly? Are there any problems that occur when using Album and how can the catalogue be changed to avoid the problems? To answer these questions I have performed a usability test in which five persons, all students, got to carry out twenty tasks in the catalogue and talk about what they were doing and thinking while doing the test. This method is a usability method called Think Aloud.

En utvärdering av Peabs inköps- och avropssystem

 This report is an evaluation of Peab's purchase and call-off system, PIA.PIA is used to order goods for Peab's construction sites. The background to the work is that users of the system have understood the system cumbersome to use when purchasing goods for construction sites. The evaluation was carried out by the interviews and tests with users of the program, in this case, supervisors and site managers at the company. Ten users of the system were interviewed and eleven people have carried out a test order.The focus is primarily on the test order that users have implemented, which has been clocked and analyzed for time and cost. The evaluation is also a user analysis concerning how the users perceive the program, mainly in terms of usability, functionality and benefits.The result of this report shows that PIA is economically profitable to use for the purchase of goods for construction sites.

Smartphones, Användare och Estetik : En Användbarhetsstudie

The Ericsson R380 is a so-called smartphone, combining an advanced mobile phone with a Personal Digital Assistant (PDA). To evaluate the usability of the Ericsson R380 and benchmark it against the Nokia 9110 Communicator and the Motorola A6188 Accompli, a repeated measurements experiment was performed. 18 subjects (10 men and 8 women) with no previous experience of any of the interfaces participated. Half of the subjects had extensive experience from using Ericsson mobile phones and half of the subjects had extensive experience from using Nokia mobile phones. A set of 9 tasks to be solved on each interface was presented to the subjects.

Optimala antalet användare i en användbarhetsutvärdering : En undersökning om hur många användare som bör vara med i en användbarhetsutvärdering för att uppnå mättnad och ett gott resultat.

Syftet med den här uppsatsen var att belysa frågan om hur många användare det behövdes för att uppnå en viss mättnad i en användbarhetsutvärdering för en specifik flash-applikation kallad My Garden. De aspekter som låg till grund för denna uppsats var brytpunkten i ökningen av unika fynd i korrelation med höga procentsatser. Med hjälp av den formativa utvärderingen och analysen av denna gick det sedan att ta reda på vilka problem (så kallade fynd) som upplevdes av användarna i gränssnittet. Resultatet av analysen resulterade i 95 unika fynd i tio användbarhetsutvärderingar. Resultatet visade följaktligen att för denna sorts utvärdering behövdes sju användare för att uppnå 93 % av alla unika fynd som hittades och därmed uppnå en slags mättnad i avklingandet av hittade unika fynd..

Förmåga till njutning - validering av en svensk version av Snaith-Hamilton Pleasure Scale

Studiens syfte var att validera en modifierad svensk översättningav självskattningsskalan som mäter anhedoni, Snaith-Hamilton PleasureScale. Syftet var också att utforska relationen mellan anhedoni och fatigue,stress, mental trötthet respektive dagtrötthet. Studiens deltagare, 60universitetsstudenter, utgjorde en icke-klinisk grupp som rekryterades medbekvämlighetsurval. Den modifierade svenska översättningen av Snaith-Hamilton Pleasure Scale uppvisade god intern konsistens, samt god konvergentvaliditet vid korrelation med anhedonirelaterade subskalor i Beck DepressionInventory. Vidare uppvisade Snaith-Hamilton Pleasure Scale starkapositiva samband med Fatigue Impact Scale respektive Mental FatigueScale, men inte med The Perceived Stress Scale respektive Epworth SleepinessScale.

Användbarheten i Business Intelligens-system : Utvecklingen av användbarheten och funktionaliteten i ett webbaserat BI-system

The purpose of this study is to evaluate an existing user interface. The company in question has a web-based user interface (available through logging in via their website), but they are interested in making the process of using the interface more convenient and the interface more accessible, so that users without a background in computing can properly manage the interface. At the same time they want to apply additional functionalities in order create and to manage increased traffic on the company?s website. For this reason it is important to take into account the issues involved in human-computer interaction (HCI) as well as aspects of cognitive psychology in order to make the tool and the web interface more usable, more motivational, and therefore more efficient and professional.

Ny betygsskala- för elevernas bästa?

This essay is a study of the government bills for a new grading scale in the Swedish schools. There have been many complaints about the current grading scale and the main problem seems to be that teachers are interpreting the criteria for certificates differently. There are two major challenges for Swedish teachers, one is how to interpret the criteria for certificates, the other one is the equality problem , students can not be sure of that two different teachers would give the same grades. The main point of the essay is to try to find out whether the new grading scale will solve this problem. To my help I have made an analysis of the bills of the Swedish government for the new grading scale.
