  1. 1. An argument principle for generalised point residues

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Rahim Nkunzimana; [2021-08-24]
    Keywords : ;

    Abstract : We define a point residue for any Artinian O-modules via Hermitian free resolutions,generalising the one dimensional residue and the classical multivariateGrothendieck point residue. We consider various definitions of multiplicity forsuch modules and prove a residue formula connecting the algebraic multiplicityto our residues. READ MORE

  2. 2. Differential Deep Learning for Pricing Exotic Financial Derivatives

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

    Author : Erik Alexander Aslaksen Jonasson; [2021]
    Keywords : Deep Learning; Exotic Derivatives; Differential Machine Learning;

    Abstract : Calculating the value of a financial derivative is a central problem in quantitative finance. For many exotic derivatives there are no closed-form solutions for present values, instead, computationally expensive Monte Carlo methods are used for valuation. READ MORE

  3. 3. Multivariate Time Series Data Generation using Generative Adversarial Networks : Generating Realistic Sensor Time Series Data of Vehicles with an Abnormal Behaviour using TimeGAN

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

    Author : Sofia Nord; [2021]
    Keywords : Time Series Data Generation; Generative Adversarial Network; Deep Neural Network; Data Augmentation; Synthetic Data Generation; Generering av Tidsseriedata; Generativa Motstridande Nätverk; Djupa Neurala Nätverk; Dataökning; Syntetisk Datagenerering;

    Abstract : Large datasets are a crucial requirement to achieve high performance, accuracy, and generalisation for any machine learning task, such as prediction or anomaly detection, However, it is not uncommon for datasets to be small or imbalanced since gathering data can be difficult, time-consuming, and expensive. In the task of collecting vehicle sensor time series data, in particular when the vehicle has an abnormal behaviour, these struggles are present and may hinder the automotive industry in its development.

  4. 4. Application of HEC-HMS modelling on River Storån,Model evaluation and analysis of the processes by using soil moisture accounting loss method

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Pooja Makki Vijayaprakash; [2021]
    Keywords : River Storån; HEC-HMS; SMA; streamflow; baseflow; evapotranspiration; Technology and Engineering;

    Abstract : River Storån, a major tributary of Lake Bolmen which is a source of fresh water to Skåne county of Sweden is found to alter the color of water in the lake due to the presence of natural organic matter. Hence it is of utmost importance to study the river to understand the dynamics of generation and flow of water from the river to the lake. READ MORE

  5. 5. From reactive maintenance towards increased proactiveness through digitalisation : Vital factors to achieve momentum towards preventive maintenance using digital tools

    University essay from Jönköping University/JTH, Industriell organisation och produktion

    Author : Jesper Liedberg; [2021]
    Keywords : underhåll; förebygande underhåll; digitalisering;

    Abstract : At today's manufacturers, reactive maintenance mostly takes place instead of prevention. At the same time, maintenance is seen as a necessary evil and many companies have no direct strategies or goals for maintenance. In today's maintenance, Industry 4. READ MORE
