1. 1. Harmonisk strömsimulering i inverterbaserade värmepumpar

   University essay from Umeå universitet/Institutionen för fysik

   Author : Alexander Magnusson; [2023]
   Keywords : Current harmonics; inverter-driven compressor; black box simulation;

   Abstract : An electrical distribution network supplies power to many households at a time. Each house has various types of electrical appliances which consume different levels of power depending on its function and the load it supplies. An ideal case would be when no appliances cause power disturbances, however, in reality, many electrical appliances (e.g. READ MORE

3. 2. System Simulation of Electric Driveline and Active Suspension using Simcenter Amesim

   University essay from Umeå universitet/Institutionen för fysik

   Author : Simon Lundberg; [2022]
   Keywords : System Simulation; Mechatronics; Amesim; Electric driveline; Active suspension;

   Abstract : Computer simulation software’s are arguably some of the most convenient and utilized tools for an engineer as it lets them model real phenomena and observe different operations without having to perform the operation physically, thus saving both time and resources. Naturally these tools varies in design depending on their intended area of application and while a large number of them supports modeling of more than one physical domain, it is often cumbersome to attain a functional interaction between them.

4. 3. Design of Instrumentation & Control and Optical Table Instruments for the Divertor Flow Monitor Diagnostic at ITER

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Niklas Hermansson; [2022]
   Keywords : Coherence imaging; fusion; optics; plasma diagnostic; polarization; spectroscopy; Zeeman-Doppler imaging;

   Abstract : This master's thesis describes the process of the design and instrument selection for a future optical table, part of a plasma flow monitor diagnostic system at the international thermonuclear experimental reactor, ITER. The diagnostic system is designed to detect the presence of edge localized mode, low to high confinement mode transition of plasma, and plasma flow velocity in the divertor region of the reactor.

5. 4. A NUMERICAL MODEL OF HEAT- AND MASS TRANSFER IN POLYMER ELECTROLYTE FUEL CELLS : A two-dimensional 1+1D approach to solve the steady-state temperature- and mass- distributions

   University essay from Mälardalens högskola/Framtidens energi

   Author : Emil Skoglund; [2021]
   Keywords : PEFC; PEM; convection; mass transport; heat transport; co-flow; temperature profile; heat transfer model; transient; steady state; water concentration profile; water vapor profile; relative humidity; through-plane cross section;

   Abstract : Methods of solving the steady state characteristics of a node matrix equation system over a polymer electrolyte fuel cell (PEFC) were evaluated. The most suitable method, referred to as the semi-implicit method, was set up in a MATLAB program. READ MORE

6. 5. Cost-efficient method forlifetime extension ofinterconnectedcomputer-based systems

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Wilhelm Holmberg; [2021]
   Keywords : COTS Cost-efficiency Emulator FPGA Lifetime extension Train identification; COTS Emulering FPGA Kostnadseffektivitet Livstidsförlängning Tågidentifiering;

   Abstract : Lifetime and obsolescence of components for computer-based systems poses issues for continued usage and maintenance of the systems. This thesis investigates possible alternatives for lifetime extension of a train identification system used in Stockholm Metro. READ MORE
