- An experimental study was carried out to investigate the possibilities to use rolls made from Si3N4-TiN ceramic composite in hot rolling of steel. The results show that the wear of the ceramic material was lower than the wear of a reference cast iron. The results suggest that the Si3N4-TiN material is beneficial to use in a hot rolling process, on condition that the temperature of the work piece material is held sufficiently high. © 2008 Elsevier B.V.

The face you recognize may not be the one you saw : Memory conjunction errors in individuals with or without learning disability
- 2006

In: Scandinavian Journal of Psychology. - : Wiley. - 0036-5564 .- 1467-9450. ; 47:3, s. 177-186

Journal article (peer-reviewed)abstract
- Memory conjunction errors, that is, when a combination of two previously presented stimuli is erroneously recognized as previously having been seen, were investigated in a face recognition task with drawings and photographs in 23 individuals with learning disability, and 18 chronologically age-matched controls without learning disability. Compared to the controls, individuals with learning disability committed significantly more conjunction errors, feature errors (one old and one new component), but had lower correct recognition, when the results were adjusted for different guessing levels. A dual-processing approach gained more support than a binding approach. However, neither of the approaches could explain all of the results. The results of the learning disability group were only partly related to non-verbal intelligence.

Pictures as cues or as support to verbal cues at encoding and execution of prospective memories in individuals with intellectual disability

Journal article (peer-reviewed)abstract
- This study focused on prospective memory in persons with intellectual disability and age-matched controls. Persons with intellectual disability have limited prospective memory function. We investigated prospective memory with words and pictures as cues at encoding and retrieval. Prospective and episodic memory was estimated from Prospective Memory Game performance. Pictures at retrieval were important for prospective memory in particular in the intellectual disability group. Prospective memory performance imposed a cost to Episodic Memory (ongoing task) performance in the intellectual disability group. This group was outperformed by the control group on working memory, time reproduction, time concepts, and Raven's coloured progressive matrices. To conclude, pictures at retrieval improve prospective memory performance compared to words as cues. This can be essential for the intellectual disability group likely due to limited episodic and working memory capacity and the ability to switch attention.

Prospective memory, working memory, retrospective memory and self-rated memory performance in persons with intellectual disability
- 2008
-
In: Scandinavian Journal of Disability Research. - : Stockholm University Press. - 1501-7419 .- 1745-3011. ; 10:3, s. 147-165
-
Journal article (peer-reviewed)abstract
- The purpose of the present study was to examine the relationship between prospective memory, working memory, retrospective memory and self-rated memory capacity in adults with and without intellectual disability. Prospective memory was investigated by means of a picture-based task. Working memory was measured as performance on span tasks. Retrospective memory was scored as recall of subject performed tasks. Self-ratings of memory performance were based on the prospective and retrospective memory questionnaire. Individuals with intellectual disability performed at a lower level on most tasks and the task performances were to a higher degree correlated compared to persons without intellectual disability. The groups did not differ in self-rated memory scores. Distinct prospective memory cues (pictures, compared to words) were essential for prospective memory performance in persons with intellectual disability. The results are discussed with respect to how working memory capacity relates to prospective memory and retrospective memory performance.

The relationship between prospective memory, working memory and self-rated memory performance in individuals with intellectual disability
- 2011

In: Scandinavian Journal of Disability Research. - : Stockholm University Press. - 1501-7419 .- 1745-3011. ; 13:3, s. 207-223
-
Journal article (peer-reviewed)abstract
- In the present study, prospective memory, working memory and self-rated memory performance were assessed in five individuals with intellectual disability and 10 individuals without intellectual disability. Prospective memory was taxed by means of a video-based procedure and a more naturalistic task, working memory was taxed by means of digit and picture span tasks, and a questionnaire was used to measure self-rated prospective and retrospective memory. The spread of performance was wide on prospective memory and working memory tasks, foremost for individuals with intellectual disability. Self-rated memory did not differ between the two groups, although there were large differences in memory performance on the other memory tasks. The results are interpreted in terms of how limitations in working memory contribute to prospective memory failures among individuals with intellectual disability. To remember ‘when to’ perform a prospective memory task seems to be more difficult to master than remembering ‘what to do’ for individuals with intellectual disability.
