AbstractTitle: Serial recall of two-voice lists: Words are not perceptually organized by voice.The present study examined how voice affects the perceptual grouping of words in short-term memory that are auditory presented. Three different voice-lists were used: single-voice, alternating-voice and split-voice. In single-voice lists all words were presented in the same voice. In alternating-voice lists words were presented alternately in a male and a female voice. Finally, in split-voice lists words were presented grouped four and four in a male and a female voice.

In many earlier investigations a recall advantage of auditory lists spoken in a single voice has been found over recall of lists spoken in two alternating voices. One explanation proposed is an organization strategy which makes recall of alternating-voice lists so difficult. The strategy implies sorting same-voice words into same-voice groups at encoding. Based on this proposition, it was assumed that voice-by-voice recall would be better than recall in order of presentation, as then the recall instruction and the organization of items in memory would be in concordance. The present experiment tested and was unable to support this hypothesis.

When searching for better and more practical interfaces between users and their computers, additional or alternative modes of communication between the two parties would be of great use. This thesis handles the possibilities of using eye and head movements as well as voice input as these alternative modes of communication. One part of this project is devoted to find possible interaction techniques when navigating in a computer interface with movements of the eye or the head. The result of this part is four different controls of an interface, adapted to suit this kind of navigation, combined together in a demo application. Another part of the project is devoted to the development of an application, with voice control as primary input method.

This Master Thesis documents the development of an On Board Diagnosis (OBD-II) interface for remote diagnosis of vehicles. The Master Thesis is part of a project at the company Wayfinder Systems in Lund. The purpose of this thesis was to design a scantool that communicates with a vehicle through its OBD-II port using relevant standards. In order to make the OBD-II interface development easier, a car simulator was first built. Both the car simulator and the OBD-II interface were implemented using a linux computer running a C-program with serial communication with an external electrical interface.

This master thesis project will describe and evaluate the interfaces between applications and Controller Area Network, CAN, interface boards from different manufacturers. The interfaces have corresponding functions but the usage of parameters is different. The simply communication of sending and receiving messages is more alike than the supplementary functions between the different interfaces. The CAN communication is more controlled by the CAN protocol and is therefore more alike. The evaluation shows differences and similarities between different interfaces and also difficulties and options to translate them.

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.

The population over 65 years of age is increasing and health in elderly has been a subject of research for decades but voice function and vocal health has not been prioritized. The purpose of this study is to obtain reference value for the Swedish version of Voice Handicap Index (RHI) and the Throat Scale among people over 65 years of age and assess voice function and vocal health for this age group. The questions were as followed:1) What is the reference value of RHI for people over 65 years of age? 2) What is the reference value of the Throat Scale for people over 65 years of age? 3) Is there a correlation between a self-rated VA-scale on the perceived degree of voice problems, and the self-rated RHI-/Throat Scale result? 4) Does age, gender or previous profession matter for the self-perceived voice?In total 100 individuals participated in the study, 50 women and 50 men, between 65 and 92 years old. The reference value of RHI for people over 65 years of age was 13,4 points and the reference value for the Throat Scale was 7,7 points.

This essay focuses on four different aspects of readability: voice, causality, advanced words and the LIX-value of words. Each of these four facilitates or aggravates reading comprehension for students, which is further defined in the paper. The study is an analysis of textbooks in history for 8th grade from a second language perspective. In terms of voice, causality, advanced words and the LIX-value of words, the study shows that books with higher grades of causality and voice and lower grades of advanced words as well as a low degree of LIX-value are better for students to work with..

For this essay we used pattern theory from interface design and applied it in an analysis of touch games. In order to make full use of the patterns, we selected five of them and adapted these slightly with the help of game related patterns to be useful for the framework of this essay. The selection of games were the top eight games on the App Store?s ?What?s Hot?. The results showed, among other things, that the games had a clear focus on getting a pleasant apperance, and they did it relatively well.

The purpose of this study was to examine if there were anychanges in quality in the voices of speech and language pathology studentsafter four years of study at the University of Gothenburg. Recordings oftwenty student voices from the first and eight semesters were evaluatedperceptually by six speech-language pathologists. The parameters judgedwere: vocal fry, glottal attacks, strain, breathiness and resonant voice, usinga scale from 0 to 10. Acoustical measures were made of F0 mean andmedian to detect possible differences between the two recordings. Theresults show a significant decrease in vocal fry, glottal attacks and strain aswell as an increase in resonant voice and a significant decrease in F0 meanand median.

The purpose of this report has been to develop an administrative web interface. The web interface is to be used by the company Zidango and it is going to make it easier for them in their daily work of running a web portal. The interface had to be developed so it would fit in Zidangos web portal. This meant the work had to be done in the framwork Struts and mostly in JAVA. Thereforeis a shorter theory chapter included in the report that discusses frameworks.

To efficiently examine volumetric data sets from CT or MRI scans good volume rendering applications are needed. This thesis describes the design and implementation of an application programming interface (API) to be used when developing volume-rendering applications. A complete application programming interface has been designed. The interface is designed so that it makes writing application programs containing volume rendering fast and easy. The interface also makes created application programs hardware independent.

This thesis investigates how different Linux-distributions installation interface relate to the ISO 9241 standard, parts 12 and 13, and how they relate to the installation interface of Windows XP, with the hypothesis: "There is a Linux-distribution whose installation interface according to applicable HCIrecommendations is equivalent to that of Windows XP." With the checklists provided by ISO 9241 an empirical study has been made, and so comparable measurements of how well the Linux-distributions and Windows XP follows the recommendations of the standard was obtained. By comparing the results from the tests similarities and differences between the installation interfaces can be deducted. As the result and the conclusion shows there are Linux-distributions whose installation interface, according to the applicable HCI-recommendations, are equivalent to that of Windows XP..

Studies indicate that between 6-9% of all children has some type of voice problems. Voice problems in children may have different etiology and can affect all ages. In Sweden, there is a lack of a standardized questionnaire addressed to children with voice problems and their legal guardians. The purpose of this study was to translate and validate the Pediatric Voice Handicap Index (pVHI) in Swedish children aged 6 to 10 years. The study was carried out through an internet-based assessment form for children referred to speech and language pathologist/ phoniatrican due to voice disorders in Sweden and a matched control group of children without voice problems.
