1. 1. Femoral shaft fractures in children and adolescents; stability, residual deformity and recovery of physical function

   Författare :Marianne Flinck; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Femoral fractures; Child; Treatment outcome; Leg length discrepancy; Elastic intramedullary nails; Biomechanics; Fracture fixation; Three-dimensional gait analysis; Function recovery;

   Sammanfattning : Femoral shaft fracture is the most common injury requiring hospital admission among children. The limited number of studies makes it challenging to provide accurate prognosis for recovery after femoral shaft fractures in children and adolescents. LÄS MER

3. 2. Particle Engineering by Spherical Crystallization:Mechanisms and Influence of Process Conditions

   Författare :Jyothi Thati; Åke Rasmuson; Stephane Veesler; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spherical agglomeration; Benzoic acid; Solubility; Phase diagram; Physico- mechanical properties size distribution; particle morphology and crushing strength; elastic recovery; compressibility ; Chemical engineering; Kemiteknik;

   Sammanfattning : Spherical agglomerates of benzoic acid crystals have been successfully prepared by drowning-out crystallization in three solvent partial miscible mixtures. Benzoic acid is dissolved in ethanol, bridging liquid is added and this mixture is fed to the agitated crystallizer containing water as the anti-solvent. LÄS MER

4. 3. Control over the Cloud : Offloading, Elastic Computing, and Predictive Control

   Författare :Per Skarin; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud; Control Theory; Model Predictive Control; Offloading; Elastic Computing; Networks; Utility Computing; Cloud Services; Internet-of-Things; Distributed Cloud; 5G Systems;

   Sammanfattning : The thesis studies the use of cloud native software and platforms to implement critical closed loop control. It considers technologies that provide low latency and reliable wireless communication, in terms of edge clouds and massive MIMO, but also approaches industrial IoT and the services of a distributed cloud, as an extension of commercial-of-the-shelf software and systems.

5. 4. Prediction of springback in sheet metal forming: with emphasis on material modeling

   Författare :Per-Anders Eggertsen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Springback; Hardening law; Elastic degradation; Yield surface; Simulation; Bauschinger effect;

   Sammanfattning : The prediction of springback is probably the area in sheet metal forming simulation, where the least success has been achieved in terms solution accuracy. The springback is caused by the release of the residual stresses in the work piece after the forming stage. LÄS MER

7. 5. Quasi-instantaneous and Long-term Deformations of High-Performance Concrete with Some Related Properties

   Författare :Bertil Persson; Avdelningen för Byggnadsmaterial; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shrinkage; Relative humidity; Long-term; Hydration; High-Performance Concrete; Elastic modulus; Deformations; Creep; Concrete; Cement; Quasi-instantaneous; Strength; Building construction; Byggnadsteknik;

   Sammanfattning : This report outlines an experimental and numerical study on quasi-instantaneous and long-term deformations of High-Performance Concrete, HPC, with some related properties. For this purpose about two hundred small cylinders and about one thousand cubes of eight types of HPC were cast. The age at loading varied between 18h and 28 days. LÄS MER
