Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Buildings Post Corona is a Swedish collaborative research project between Chalmers, KTH Royal Institute of Technology, Lund, and Umeå Universities. The project supports the building sector in designing and maintaining sustainable buildings with a healthy and good indoor environment. The COVID-19 crisis has stressed the importance and urge of this research.The scope of the project is to develop a methodology for the operation and design of buildings with an indoor environment that meets future health and climate challenges. The project’s overall goal is to establish an interdisciplinary platform to document existing experiences and knowledge and to gain new knowledge required for good building design and operation.

- I denna debattartikel lyfter sex forskare frågan att myndigheter och branschorganisationer delvis gav olika råd kring åtgärder för att begränsa risken för smittspridning inomhus. För att klara nästa pandemi krävs bättre samordning av riktlinjer kring ventilation och luftkvalitet.

Modelling and simulation of local mechanical properties of high silicon solution-strengthened ferritic compacted graphite iron
- 2017
-
Ingår i: International Journal of Cast Metals Research. - : Taylor & Francis Group. - 1364-0461 .- 1743-1336. ; 30:3, s. 125-132

Tidskriftsartikel (refereegranskat)abstract
- This study focuses on the modelling and simulation of local mechanical properties of compacted graphite iron cast at different section thicknesses and three different levels of silicon, ranging from about 3.6% up to 4.6%. The relationship between tensile properties and microstructure is investigated using microstructural analysis and statistical evaluation. Models are generated using response surface methodology, which reveal that silicon level and nodularity mainly affect tensile strength and 0.2% offset yield strength, while Young′s modulus is primarily affected by nodularity. Increase in Si content improves both the yield and tensile strength, while reduces elongation to failure. Furthermore, mechanical properties enhance substantially in thinner section due to the high nodularity. The obtained models have been implemented into a casting process simulation, which enables prediction of local mechanical properties of castings with complex geometries. Very good agreement is observed between the measured and predicted microstructures and mechanical properties, particularly for thinner sections.

Studier av läsrelaterade språkliga förmågor i förskola och läsutveckling i grundskola

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of this doctoral thesis was to explore relationships that impact language development, and how reading ability develops during the compulsory school years. The thesis includes four studies, study I (licentiate thesis), with students from grades 2–5, from 24 classrooms (N = 428), study II examined whether the National test (NP) was able to identify students with word decoding problems from a sample of third graders from study I (n= 112). In study III a small number of students (n = 8) from Study II were followed-up to the ninth grade. The students’ and their parents’ perception of special education support is described.In Study IV the correlation between socioeconomic status (SES) and language development was examined in preschool children (N= 231) from three municipalities in the middle of Sweden. Furthermore, the language ability among these preschool boys and girls is described. Students’ language abilities are examined in these four studies, where the participants are students in preschool (N= 231), and compulsory school (N=428).The results indicated that the student’s reading profiles (the correlation between phonological decoding and reading ability) based on Simple View of Reading showed difficulties in reading ability for students in the fourth grade to a larger extent than in the third grade. National tests (NP) in Swedish for the third grade do not identify students with decoding difficulties.The students that had difficulties with decoding in the third grade also had difficulties with decoding in the ninth grade and scored low on all reading and writing tests. In interviews with parents and students, the respondents described that the students did not engage in leisure reading in their free time and that when they did, they read using their computer or their mobile phone. The respondents also described school experiences where special education support had been provided too late, and to an unsatisfactory extent. Between the fourth and sixth grade, special support was provided as reading in a small group, and between the seventh and ninth grade, special support was provided from a paraprofessional; receiving support from a special educational needs teacher was uncommon. Study IV does not indicate differences between preschool boys’ and girls’ results on tests in language abilities, letter knowledge, and rapid automatized naming. Children from areas with lower SES performed worse on the language tests than children from areas with higher SES. The results from these studies indicate the importance of early language interventions for preschool children in areas with low SES. Taken together, the studies indicate that the early identification of children with delays in language abilities is feasible in preschool, as well as the early identification of children with difficulties with decoding in primary school. The follow-up suggests that without early and effective interventions the difficulties may last for the following school years, and may affect negatively the students’ educational achievement.

An anisotropic non-linear material model for glass fibre reinforced plastics
- 2018
-
Ingår i: Composite structures. - : Elsevier. - 0263-8223 .- 1879-1085. ; 195, s. 93-98
-
Tidskriftsartikel (refereegranskat)abstract
- This paper aims to present a methodology to predict the anisotropic and non-linear behaviour of glass fibre reinforced plastics using finite element methods. A material model is implemented in order to remedy the need of multiple material definitions, and to control the local plastic behaviour as a function of the fibre orientation. Injection moulding simulations traditionally provide second order orientation tensors, which are considered together with a homogenization scheme to compute local material properties. However, in the present study, fourth order tensors are used in combination with traditional methods to provide more accurate material properties. The elastic and plastic response of the material model is optimized to fit experimental test data, until simulations and experiments overlap. The proposed material model can support design engineers in making more informed decisions, allowing them to create smarter products without the need of excessive safety factors, leading to reduced component weight and environmental impact.
