   Sammanfattning : Two-dimensional (2D) nanocomposites based on cellulose nanofibrils (CNF) and 2D nanomaterials are of interest as sustainable materials combining functional and structural properties. To achieve reinforcement effects from 2D nanomaterials, their orientation and dispersion state in the CNF matrix are important. LÄS MER

4. 18. The Quest for Robust Model Selection Methods in Linear Regression

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model selection; information criterion; linear regression; sparsity; high dimensional; Electrical Engineering; Elektro- och systemteknik; Mathematical Statistics; Matematisk statistik;

   Sammanfattning : A fundamental requirement in data analysis is fitting the data to a model that can be used for the purpose of prediction and knowledge discovery. A typical and favored approach is using a linear model that explains the relationship between the response and the independent variables. LÄS MER

5. 19. Studies of the fibre direction and local bending stiffness of Norway spruce timber : for application on machine strength grading

   Författare :Min Hu; Marie Johansson; Mats Ekevad; Linnéuniversitetet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; digital image correlation; diving angle; fibre angle; grain angle; indicating property; laser scanning; modulus of elasticity; tracheid effect; Forestry and Wood Technology; Skog och träteknik;

   Sammanfattning : Machine strength grading is a production process in the sawmill industry used to grade sawn timber boards into different strength classes with specific characteristic values of the bending strength, modulus of elasticity (MOE) and density. These properties are called grade determining properties. LÄS MER

7. 20. Investigating polymorphism in small molecules using three-dimensional electron diffraction

   Författare :Molly Lightowler; Xiaodong Zou; Hosea M. Nelson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 3D electron diffraction; structure determination; polymorphism; crystallisation; phase identification; small molecule; oorganisk kemi; Inorganic Chemistry;

   Sammanfattning : For scientific, regulatory and intellectual property reasons, the discovery and characterisation of polymorphic systems is an integral aspect of the development process of any solid-formulated drug product. Yet, these studies are often hindered by crystal quality and size, poor yields and the generation of mixtures of phases. LÄS MER
