  1. 21. Probabilistic Assessment of the Risk of Cargo Shifting Onboard Ships in Waves

    Author : Anna Ryrfeldt; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ship roll; cargo shifting; probabilistic model; waves; ship dynamics; risk;

    Abstract : This thesis is the result of work within the research project "Probabilistic Models for Ship Safety in Rough Seas". One major danger in sea transportation is the shifting of cargo. The aim of the project has been to develop a methodology for assessing the risk of cargo shifting as well as performing some case studies. READ MORE

  2. 22. A specific heat ratio model and compression ratio estimation

    Author : Marcus Klein; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Cylinder pressure modeling and heat release analysis are today important and standard tools for engineers and researchers, when developing and tuning new engines. An accurate specific heat ratio model is important for an accurate heat release analysis, since the specific heat ratio couples the systems energy to other thermodynamic quantities. READ MORE

  3. 23. PMU-based State Estimation for Hybrid AC and DC Grids

    Author : Wei Li; Luigi Vanfretti; Hao Zhu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Power system state estimation plays key role in the energy management systems(EMS) of providing the best estimates of the electrical variables in the grid that arefurther used in functions such as contingency analysis, automatic generation control,dispatch, and others. The invention of phasor measurement units (PMUs) takes thepower system operation and control into a new era, where PMUs’ high reportingrate and synchronization characteristics allow the development of new wide-areamonitoring, protection, and control (WAMPAC) application to enhance the grid’sresiliency.

  4. 24. Offshore Marine Substation for Grid-Connection of Wave Power Farms : An Experimental Approach

    Author : Rickard Ekström; Karin Thomas; Frans Dijkhuizen; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; Offshore Marine Substation; Grid-Connection; Electrical Systems; Voltage-Source Inverter; On-load Tap Change; Cascaded H-bridge Multilevel Inverter; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Wave power is a renewable energy source with great potential, which is why there are more than a hundred ongoing wave power projects around the world. At the Division of Electricity, Uppsala University, a point-absorber type wave energy converter (WEC) has been proposed and developed. READ MORE

  5. 25. Robust Image Registration for Improved Clinical Efficiency : Using Local Structure Analysis and Model-Based Processing

    Author : Daniel Forsberg; Hans Knutsson; Mats Andersson; Claes Lundström; Wiro Niessen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Image registration; deformable models; scoliosis; visualization; volume rendering; adaptive regularization; GPGPU; CUDA;

    Abstract : Medical imaging plays an increasingly important role in modern healthcare. In medical imaging, it is often relevant to relate different images to each other, something which can prove challenging, since there rarely exists a pre-defined mapping between the pixels in different images.
