  1. 11. Forecasting Volatility of Ether- An empirical evaluation of volatility models and their capacity to forecast one-day-ahead volatility of Ether

    University essay from Göteborgs universitet/Graduate School

    Author : Johannes Marmdal; Adam Törnqvist; [2023-06-29]
    Keywords : Forecast; Volatility; Ether; GARCH; EWMA; SMA;

    Abstract : This study evaluates the performance of volatility models in forecasting one-day-ahead volatility of the cryptocurrency Ether. The selected models are: GARCH, EGARCH, GJR-GARCH, SMA9, SMA20, and EWMA. We investigate both in-sample performance and out-of-sample performance. READ MORE

  3. 12. MetaStackVis: Visually-Assisted Performance Evaluation of Metamodels in Stacking Ensemble Learning

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Ilya Ploshchik; [2023]
    Keywords : Visualization; interaction; metamodels; validation metrics; predicted probabilities; stacking; stacked generalization; ensemble learning; machine learning;

    Abstract : Stacking, also known as stacked generalization, is a method of ensemble learning where multiple base models are trained on the same dataset, and their predictions are used as input for one or more metamodels in an extra layer. This technique can lead to improved performance compared to single layer ensembles, but often requires a time-consuming trial-and-error process. READ MORE

  4. 13. Analog mixed signal front-end for Torque signal processing : A theoretical noise analysis and signal-chain evaluation

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

    Author : Jesper Jansson; Wilhelm Nordgren; [2023]
    Keywords : Torque sensor; noise analysis; signal processing; analog-to-digital conversion; Momentgivare; brusanalys; signalbehandling; analog-till-digital omvandling;

    Abstract : High precision tightening of nuts and bolts together with traceability are important in many industrial assembly lines. To achieve this the nutrunner needs to accurately measure the torque which is applied to the nut, process the signal and provide the information to the controller that controls the tightening process.

  5. 14. AC Gate Bias Stress of 4H-SiC MOSFETs : An investigation into threshold voltage instability of SiC Power MOSFETs under the influence of bipolar gate stress

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

    Author : Agnimitra Saha; [2023]
    Keywords : Silicon Carbide; Gate Bias Stress; Threshold Voltage; On-state Resistance; Temperature; kiselkarbid; gate spännings-stress; tröskelspänning; on-resistansen; temperatur;

    Abstract : Silicon Carbide, a wide band gap (WBG) semiconductor, has pushed electrical limits beyond Silicon (Si) when it comes to power electronics. It has offered the electrification of society showing promise for a greener future. READ MORE

  6. 15. Circularity indicators in practice: Exploring companies’ application and linkages to sustainability

    University essay from Lunds universitet/Internationella miljöinstitutet

    Author : Emilia Paulina Paredes Bassi; [2023]
    Keywords : circular economy; circularity indicators; circularity assessment; sustainability assessment; industry; Chile; Social Sciences;

    Abstract : The Circular Economy (CE) has gained global recognition as a way to enable sustainability improvements in production and consumption systems. Numerous circularity indicators (c-indicators) have been developed by academia and practitioners to be used at the company level as analytical tools to measure progress towards a more circular economy.
