2. 1. Cooperative Compressive Sampling

   Author : Ahmed Zaki; Lars Kildehøj; Saikat Chatterjee; Jan Østergaard; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compressive sampling; greedy algorithms; convex optimisation; RIP analysis; fusion strategy; distributed learning; sparse learning; stochastic matrix; consensus; sparse estimation; Telecommunication; Telekommunikation;

   Abstract : Compressed Sampling (CS) is a promising technique capable of acquiring and processing data of large sizes efficiently. The CS technique exploits the inherent sparsity present in most real-world signals to achieve this feat. Most real-world signals, for example, sound, image, physical phenomenon etc., are compressible or sparse in nature. READ MORE

4. 2. Optimization of Compressive Crushing

   Author : Elisabeth Lee; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cone Crusher; Modeling; Compressive Crushing; Implementation; Optimization;

   Abstract : With almost all infrastructures being dependent on the supply of crushed rock materials,minerals, and ores, it is fair to say that the foundation of modern society is literally built uponthese materials. As society continues to develop and standards of living progressivelyincrease, the subsequent growing demand for crushed rock materials, minerals, and ores willresult in a need for improving the performance and efficiency of rock crushing equipment.

5. 3. On Cohesive Modelling of Carbon/Epoxy Composites : Delamination and Fibre Compressive Failure

   Author : Daniel Svensson; Ulf Stigh; Bent Sørensen; Högskolan i Skövde; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFRP; Cohesive zone model; J-integral; LEFM; Delamination; Compressive failure; Technology; Teknik; Mechanics of Materials; Materialmekanik;

   Abstract : Carbon Fibre Reinforced Polymers are widely used in engineering applications where weight saving and high mechanical performance are a key factors. However, an inheren tweakness of laminated CFRP:s is there relatively low resistance to delamination. Therst part of this thesis is devoted to extract cohesive laws associated with delamination.

6. 4. Theoretical Optimization of Compressive Crushing

   Author : Elisabeth Lee; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Consumption; Fitness Function; Genetic Evolutionary Algorithms; Crushing Pressure; Optimization; Product Yield; Compressive Crushing;

   Abstract : Surrounded by products made from crushed rock materials in all corners of society, most people do not spend much time thinking about when, where, or how these are produced. In fact, most people take the supply and availability of products made from crushed rock materials for granted. READ MORE

7. 5. Compressive failure of unidirectional NCF composites

   Author : Dennis Wilhelmsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerospace; Fibre misalignment; Compressive failure; NCF composite;

   Abstract : With more people flying every year, new technologies are needed to reduce our impact on the environment. One option is to reduce the energy used in flight by introducing lighter materials such as carbon fibre reinforced polymers (CFRP). READ MORE
