  1. 1. Workload Detection and Continuous Automatic Bayesian Optimization in Database Management Systems

    University essay from Lunds universitet/Institutionen för datavetenskap

    Author : Jonas Boström; Viktor Olsson; [2022]
    Keywords : Technology and Engineering;

    Abstract : The goal of this thesis has been to investigate the possibility of multi-workload optimization in Database Management Systems and workload detection. A system was successfully constructed to allow for multi-workload testing and data aggregation. READ MORE

  3. 2. Object Tracking Achieved by Implementing Predictive Methods with Static Object Detectors Trained on the Single Shot Detector Inception V2 Network

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Richard Dan William Barkman; [2019]
    Keywords : Supervised Machine Learning; Hyperparameter Optimisation; Convolutional Neural Networks; Lagrangian Mechanics; Predictive Methods;

    Abstract : In this work, the possibility of realising object tracking by implementing predictive methods with static object detectors is explored. The static object detectors are obtained as models trained on a machine learning algorithm, or in other words, a deep neural network. READ MORE

  4. 3. Modelling the Formation and Propagation of Orographic Rossby Waves

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Eskil Jonsson; [2017]
    Keywords : Global model; shallow fluid approximation; middle-high troposphere; potential vorticity conservation; Global modell; grund fluid approximation; mellan-övre troposfären; potentiell vorticitetsbevarande;

    Abstract : Orographic Rossby waves are the main mechanism by which the jet streams meander aroundthe Earth and have possibly far-reaching impacts on weather and climate (chapter 1). Hence,they are of particular importance to study and this project should serve as a starting point inwhat to consider when trying to model these waves. READ MORE

  5. 4. What makes a good language test in EFL?

    University essay from Göteborgs universitet/Institutionen för språk och litteraturer

    Author : Jani Lemmetti; [2015-03-10]
    Keywords : Engelska; Läraruppsats; Language testing; validity; reliability; washback;

    Abstract : Language testing is a fundamental part of learning and teaching in school today, and has been throughout history even though views on language testing have changed. This paper reports on what r e s e a r ch says regarding the various components that are needed when constructing and using a language test. READ MORE
