1. Om livets kontinuitet. Undervisning och lärande om växters och djurs livscykler - en fallstudie i årskurs 5
Sammanfattning : The aim of this thesis is to contribute to increased understanding of teaching and learning about life cycles, when the teaching is based on living organisms and the teacher is introduced to ideas of research on pupils’ ideas and formative assessment. This aim is addressed by investigating the pupils’ learning as well as their experiences of the living organisms, inquiring into the teachers’ competence and by describing the actual teaching.

2. Microstructure and mechanical properties of low-temperature hot isostatic pressed Ti-6Al-4V manufactured by electron beam melting
Sammanfattning : Ti-6Al-4V manufactured by electron beam melting Keywords: Additive manufacturing, high-temperature tensile properties, low cycle fatigue, neutron diffraction, fatigue crack growth ISBN: 978-91-89325-27-2 (Printed) 978-91-89325-26-5 (Electronic) Ti-6Al-4V is the most widely used α+β titanium alloy in aerospace engine applications due to its high specific strength. Typically, the alloy is manufactured as castings or forgings and then machined to final geometry. LÄS MER
3. Analysis of enterprise IT service availability : Enterprise architecture modeling for assessment, prediction, and decision-making
Sammanfattning : Information technology has become increasingly important to individuals and organizations alike. Not only does IT allow us to do what we always did faster and more effectively, but it also allows us to do new things, organize ourselves differently, and work in ways previously unimaginable.

4. Effect of climate and land use on niche utilization and distribution of nettle-feeding butterflies
Sammanfattning : Anthropogenic changes in climate and land use are causing a dramatic erosion of biodiversity. To understand this erosion, and predict future transformations of biodiversity, we need to understand better species’ response to these changes at different spatial and temporal scales. LÄS MER
5. An Ontological Approach to support Knowledge Sharing between Product Design and Assembly Process Planning (APP)
Sammanfattning : Modern manufacturing organizations have to cope with several critical issues arising from the need for mass customization such as short product life-cycles, an increasing number of product variants and frequently changing customer requirements. One of the main factors that could aid overcoming those challenges is the use of information and communication technology (ICT) applications over a collaborative manufacturing environment, in which all stakeholders share and exchange knowledge across different manufacturing domains and applications.
