Alternativa metoder för att kontrollera ett användargränsnitt i en browser för teknisk dokumentation

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.

Syntaktisk komplexitet hos ungdomar och vuxna med läs- och skrivsvårigheter

The purpose of this thesis is to investigate if there are any differences regarding syntactic complexity in written language between persons with (phonologically based) reading and writing difficulties and a control group. Earlier research has pointed to such a difference, indicating that texts written by subjects with reading and writing difficulties display a lower grade of syntactic complexity than text written by control groups.Two texts each from 48 subjects (24 from each category) were collected. The subjects were divided in two age groups, one consisting of 15-year-olds and the other of university students (adults in various ages). The subjects were selected through a word decoding test and a spelling test, where the lowest performing formed the group of reading and writing difficulties and the highest performing formed the control groups. All subjects had Swedish as their mother tongue.The syntactic aspects studied were number of words per syntactic sentence (Sw.

Adaptive QoS Management in Dynamically Reconfigurable Real-Time Databases

During the last years the need for real-time database services has increased due to the growing number of data-intensive applications needing to enforce real-time constraints. The COMponent-based Embedded real-Time database (COMET) is a real-time database developed to meet these demands. COMET is developed using the AspeCtual COmponent-based Real-time system Development (ACCORD) design method, and consists of a number of components and aspects, which can be composed into a number of different configurations depending on system demands, e.g., Quality of Service (QoS) management can be used in unpredictable environments. In embedded systems with requirementson high up-time it may not be possible to temporarily shut down the system for reconfiguration. Instead it is desirable to enable dynamic reconfiguration of the system, exchanging components during run-time.

Site preparation, planting position and planting stock effects on long-term survival, growth and stem form properties of Pinus contorta on southern Iceland

In order to evaluate different afforestation methods for exposed heath lands a field experiment was established in Mosfell on southern Iceland in 1989. The trial comprised six different site preparation methods (control, herbicide application, tree shelters, patch scarification, TTS trenching and mounding). In total 960 container seedlings (1+0) and 960 Nisula roll transplants (2+1) of lodgepole pine were planted. Various planting positions (furrow, hinge, no site preparation (control) and on top of mounds) were tested within the site preparation treatments. This study involves renewed measurements and analyses of the trial.After 19 years the overall survival was 51,7 %.

Effekter av 20 minutrs daglig fysisk träning av kondition, styrka, rörlighet och balans. : En 10 veckors interventionsstudie av kvinnliga lokalvårdare

Public health focuses on interventions related to physical activity during leisure and at work under conditions where health care is offered during working hours. Increased physical activity offers many positive effects on health in general and reduces the risk for most injuries and illnesses. Female cleaners represent a profession that is largely composed of women at high risk of overload injury and rarely participate in wellness initiatives offered at workplace. The purpose of this study was to investigate the effects of 20 minutes of daily physical exercise for 10 weeks of intervention for healthy female cleaners. A total of 40 female cleaners in a larger organization participated in the study and were divided in into an intervention group and a control group.

Val av överlastskydd för elektriska ventilmanöverdon på kärnkraftverket i Forsmark

At nuclear power plants, electrical valve actuators are important for ensuring that the reactor core is water covered and the pressure in the reactor tank and containment is limited. The electrical actuators are provided with overload protection in case of drawing higher current then the motors are rated for. When safety manoeuvres are needed, the overload protection must not trig and cause the valve to stop before completing the manoeuvre. Analyses have showed that the current settings of the overload protection may cause an illegitimate trig at the worst theoretically possible accident. A new method has been developed with conservative assumptions and applies overload protections for all electrical valve actuators at the three reactors in Forsmark..

Pilotstudie för att utvärdera effekten av L-Mesitran : honungsbaserad sårsalva : vid behandling av yt-pyodermi hos hund.

Green manuring is a way of creating an organic fertilizer by growing a crop that is mowed down. Besides the fertilizing effect this method has been shown to have a positive influ-ence on soil organic matter as well as weed flora, and green manure is an important me-thod of weed control in organic farming in parts of Sweden. However, the release of nu-trients from the green manure varies and can therefore be difficult to control. Risks for losses of nutrients are also present. Although the area of organic farmland is increasing in Sweden, the use of green manure is decreasing.This report contains a literature study which compiles research on the functions of green manure in a cropping system and also how the crop can be used if harvested, for example to produce biogas.

Bara, bara vara "vänner" : En explorativ studie av den professionella socialarbetarens användande av sociala medier inom socialtjänsten

This study shows that the informants are very restrictive with what information (text and pictures) they publish on their facebook-profiles, because of their position of authority and the awareness of the possibility of always being watched.
