  1. 1. Randomized Diagonal Estimation

    University essay from KTH/Matematik (Avd.)

    Author : Niclas Joshua Popp; [2023]
    Keywords : Diagonal estimation; randomized numerical linear algebra; low-rank approximation; matrix functions; Diagonalestimering; randomiserad numerisk linjär algebra; lågrankad approximation; matrisfunktioner;

    Abstract : Implicit diagonal estimation is a long-standing problem that is concerned with approximating the diagonal of a matrix that can only be accessed through matrix-vector products. It is of interest in various fields of application, such as network science, material science and machine learning. READ MORE

  3. 2. Investigation of Influential Contexts on Mining-front Seismicity at Kiirunavaara Mine

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Bernardo Filizzola; [2023]
    Keywords : ;

    Abstract : Mining at great depths has become the reality for the mining industry in Sweden, that faces challenges in terms of increasing seismic events and sometimes intrinsically related rock mass failure. Kiirunavaara mine is owned by LKAB (located at north Sweden) and the company has been dealing with seismicity in a daily basis once the mine has been regarded as seismically active since 2007-2008 and presently has the largest seismic monitoring system in the world.

  4. 3. Towards a Reliable and Valid Analysis of VO2m Off-Kinetics

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Hrafnkell Þráinsson; [2022]
    Keywords : Sports Technology; Near-infrared spectroscopy; Muscle oxidative capacity; Occlusion; Software; Automation; Idrottsteknologi; Near-infrared spectroscopy; Muskulaturens oxidativa förmåga; Ocklusion; Programvara; Automatisering;

    Abstract : Non-invasive methods to evaluate skeletal muscle oxidative capacity have beenemerging as a viable substitute for invasive methods in recent years. One ofthose methods utilises near-infrared spectroscopy (NIRS) to calculate V O2mrecovery off-kinetics following an exercise. READ MORE

  5. 4. Use of Thermal Analysis to reduce the Microporosity in ductile iron. : Analysis of micro porosity casting defect

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Adriana Mura; [2022]
    Keywords : Nucleation; Ductile Cast iron; Inoculation; Preconditioning; Over-inoculation; Charge materials; Hypoeutectic; Eutectic; Hypereutectic; Shrinkage;

    Abstract : It became always more important in Cast Iron Foundry to have a process control system that helps to reduce the variability and follow the correct specifications, to simplify the detection of eventual inoculation problems or incorrect working ranges.In the thesis, it is presented a case study of a specific defect of microporosity that appeared in the internal areas of some castings.

  6. 5. The Effect of Whole-Body Vibration Preconditioning on High-Altitude-Induced Venous Gas Emboli

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Tommaso Tuci; [2020]
    Keywords : Whole-Body Vibration; Vibration; High-Altitude Aviation; Venous Gas Emboli; VGE; Decompression sickness; DCS;

    Abstract : Decompression sickness (DCS) is a risk associated with high-altitude aviation and diving. During these activities, decompression may lead to supersaturation of inert gas dissolved in bodily tissues and subsequently activate bubble formation in various bodily tissues, including in venous blood, known as venous gas emboli (VGE).
