  1. 1. MRI Signals Simulation for Validation of a New Microvascular Characterization

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Aurélien Delphin; [2019]
    Keywords : MRI; fingerprinting; simulations; MRVox2D;

    Abstract : Conventional MRI techniques are not convenient when it comes to study cerebral microvascularization due to the length of the scans needed. A technique called Magnetic Resonance Fingerprinting (MRF) is an excellent candidate to solve this problem as it requires much shorter scan durations. READ MORE

  2. 2. CFD simulation of dip-lubricated single-stage gearboxes through coupling of multiphase flow and multiple body dynamics : an initial investigation

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Nasir Imtiaz; [2018]
    Keywords : transmissions; churning losses; CFD; STAR-CCM ; FZG gearbox; planetary gearbox; RBM; MRF; unsteady framework; VOF; immiscible; overset meshing technique;

    Abstract : Transmissions are an essential part of a vehicle powertrain. An optimally designed powertrain can result in energy savings, reduced environmental impact and increased comfort and reliability. Along with other components of the powertrain, efficiency is also a major concern in the design of transmissions. READ MORE

  3. 3. A Study on Manual and Automatic Evaluation Procedures and Production of Automatic Post-editing Rules for Persian Machine Translation

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : Nasrin Mostofian; [2017]
    Keywords : machine translation; Persian; automatic post-editing;

    Abstract : Evaluation of machine translation is an important step towards improving MT. One way to evaluate the output of MT is to focus on different types of errors occurring in the translation hypotheses, and to think of possible solutions to fix those errors. READ MORE

  4. 4. Numerical simulation of particle soiling in the engine compartment of a bus

    University essay from Chalmers tekniska högskola/Institutionen för tillämpad mekanik

    Author : Lindberg Simon; [2015]
    Keywords : cfd; soiling; engine compartment; lagrangian; steady; MRF; porous media; dirt;

    Abstract : The location of the air intake of a bus creates challenges from a soiling perspective. The proximity to the rearwheels pulls up dirt from the road. Compared to a commercial truck, with the fan placement in the front ofthe vehicle the air intake of a bus can’t rely on ram air pressure to get the sufficient cooling air mass flow. READ MORE

  5. 5. Simulating propeller and Propeller-Hull Interaction in OpenFOAM

    University essay from KTH/Marina system

    Author : Reza Mehdipour; [2014]
    Keywords : CFD; OpenFOAM; AMI; MRF; Open Water Characteristics; Self-Propelled Ship; Scalability; Parallel Computing;

    Abstract : This is a master’s thesis performed at the Department of Shipping and Marine Technology research group in Hydrodynamics at Chalmers University of Technology and is written for the Center for Naval Architecture at the Royal Institute of Technology, KTH.In order to meet increased requirements on efficient ship propulsions with low noise level, it is important to consider the complete system with both the hull and the propeller in the simulation.
