  1. 21. Wireless communication using metasurfaces for condition monitoring in motor

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

    Author : Neelu Kambisseri Roby; [2018]
    Keywords : Gap waveguide; metasurface; holey electromagnetic band gap EBG structures; periodic structures; parallel plate mode.; Gap vågledare; metaytor; håliga elektromagnetiskta bandgap-strukturer EBG ; periodiska strukturer; parallellplattform.;

    Abstract : Wireless sensors are used widely for condition monitoring in electric machines. The metal enclosure of an electric motor restricts the signal from sensors to radiate outside. The signal from the metal cavity needs to be guided to the only opening in the enclosure, through a narrow gap between the stator and the rotating rotor. READ MORE

  3. 22. Ultra-Thin Ag Films on the Sn/Si(111)-√3×√3 Surface Studied by STM

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Rasmus Lavén; [2018]
    Keywords : Silver; Silicon; Tin; Metal-semiconductor interfaces; Thin metal films; Scanning tunneling microscopy; Quantum size effects;

    Abstract : The growth of atomically flat silver films on Si(111) usually requires a two-step growth, including deposition at low temperature (≈100 K) followed by slowly annealing to room temperature. In addition, flat silver films are usually only obtained on Si(111) for film thicknesses larger than the critical thickness of 6 monolayer. READ MORE

  4. 23. Sequence Correlations in HP Model Proteins

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Orestes Theodoridis; [2018]
    Keywords : Physics and Astronomy;

    Abstract : Amino acids that are in close contact in a protein structure tend to co-evolve, which gives rise to sequence correlations. Direct coupling analysis (DCA) is a method for predicting such contacts directly from sequence correlations, without assuming any prior knowledge of structures. READ MORE

  5. 24. Testing Direct Coupling Analysis on HP Model Proteins

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Mustafa Kadhim; [2018]
    Keywords : Direct Coupling Analysis HP model proteins; Physics and Astronomy;

    Abstract : Direct coupling analysis (DCA) models correlations in sets of related (homologous) protein sequences using a Potts-like spin model ansatz. From the couplings of the Potts model, derived by inverse statistical mechanics, residue-pair contacts in the 3D structure of the protein are predicted. READ MORE

  6. 25. Simulation study of phononic crystal structures

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Olivier Vizuete; [2017]
    Keywords : ;

    Abstract : Thermoelectric materials are important in today’s society with a variety of applications. The material properties that determinate the efficiency of a thermoelectric device are mostly constants. In order to develop more efficient thermoelectric devices new materials and solutions need to be made. READ MORE
