2. 1. Numerical modelling of geomaterials at failure

   Author : Alex Spetz; Byggnadsmekanik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soil-structure interaction; soil plasticity; phase-field fracture model; compression driven fractures; artificial rock; porous rock; finite element analysis; isogeometric analysis; NURBS; numerical methods;

   Abstract : Geotechnical engineering is the science dealing with mechanics of soils and rocks and its engineering applications. Geotechnical engineering projects vary in a wide range, from evaluation of the stability of natural slopes and man-made soil deposits, to the design of earthworks and foundations. READ MORE

4. 2. Investigating Spatial Data Infrastructure Planning in Tanzania using System Modelling and Social Concepts

   Author : Alex Lubida; Institutionen för naturgeografi och ekosystemvetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spatial Data Infrastructure; System Dynamics technique; Agent Based Modeling; Community of Practice; Multi- Objective Optimization; Land use planning;

   Abstract : Spatial Data Infrastructure is one of the requirements for sustainable development and many countries worldwide are at different stages of implementation. Several researchers have shown that SDI has helped governments to recover funds due to reduction in duplication of efforts and also has increased efficiency in resource management and planning.

5. 3. Molecular Exchange in Colloidal Dispersions

   Author : Alex Evilevitch; Kemiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; charged micoremulsion droplets; kinetics; mechanism.; Physical chemistry; Fysikalisk kemi; molecular transport; cell model; infinite dilution limit; turbidity measurements; oil solubilization; computer simulation; modeling; monomer diffusion; molecular exchange; Microemulsion droplets; oil droplets;

   Abstract : This thesis is a study of molecular exchange between the aggregates in a colloidal dispersion. The problem of oil molecular transport at resolubilization of big oil drops by smaller microemulsion droplets is considered as an experimental model system. READ MORE

6. 4. Unobtrusive Augmentation  of Physical Environments : Interaction Techniques, Spatial Displays and Ubiquitous Sensing

   Author : Alex Olwal; Steven Feiner; Lennart Johnsson; Yngve Sundblad; Mark Billinghurst; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datalogi;

   Abstract : The fundamental idea of Augmented Reality (AR) is to improve and enhance our perception of the surroundings, through the use of sensing, computing and display systems that make it possible to augment the physical environment with virtual computer graphics. AR is, however, often associated with user-worn equipment, whose current complexity and lack of comfort limit its applicability in many scenarios. READ MORE

7. 5. Ion-Crosslinked Nanocellulose Hydrogels for Advanced Wound Care Applications

   Author : Alex Basu; Natalia Ferraz; Pentti Tengvall; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanofibrillated cellulose; wood nanocellulose; ion crosslinking; hydrogel; wound healing; biocompatibility; blood interactions; bacterial interactions; protein carrier; nanotherapeutic; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

   Abstract : A current trend in the field of wound care is the development of wound healing materials that are designed to address specific types of wounds or underlying pathologies to achieve improved healing. At the same time, there is a societal drive to replace synthetic materials with renewable alternatives. READ MORE
