  1. 1. Sound Pattern Recognition : Evaluation of Independent Component Analysis Algorithms for Separation of Voices

    University essay from KTH/Skolan för teknikvetenskap (SCI); KTH/Skolan för teknikvetenskap (SCI)

    Author : David Mainwaring; Jonathan Österberg; [2018]
    Keywords : ;

    Abstract : With computers being used for more applications where commands can be spoken it is useful to findalgorithms which can separate voices from each other so that software can turn spoken words intocommands. In this paper our goal is to describe how Independent Component Analysis (ICA) can beused for separation of voices in cases where we have at least the same number of microphones, atdifferent distances from the speakers, as speakers whose voices we wish to separate, the so called``cocktail party problem".

    Abstract : Mapping the Earth’s surface and its rapid changes with remotely sensed data is a crucial tool to un-derstand the impact of an increasingly urban world population on the environment. However, the impressive amount of freely available Copernicus data is only marginally exploited in common clas-sifications. READ MORE

  3. 3. Quality assessment and epistemic beliefs : If you tell me what you believe in, can I tell you what you’ll get?

    University essay from Umeå universitet/Institutionen för naturvetenskapernas och matematikens didaktik

    Abstract : Bedömning av kvaliteten är en av de viktigaste processerna som en lärare utför varje arbetsdag för att kunna relatera elevernas prestationer mot ett kulturellt och individuellt anpassat betygssystem. Med ambitionen att främja jämställdhet och reliabilitet av bedömningar tillhandahåller Skolverket bedömningskrav och kriterier för att skilja olika grader av kvalitet (Selghed 2011). READ MORE

    Abstract : Consumption-based environmental impact trends for the Swedish economy have been generated and analysed in order to determine their levels compared to official production-based data, and to determine whether or not the Swedish economy has decoupled growth in domestic final demand from worldwide environmental impact. Three energy resources (oil, coal and gas use, as well as their aggregate fossil fuel use) and seven emissions (CO2, CH4, N2O, SO2, NOx, CO and NMVOC, as well as the aggregate CO2 equivalents) were studied.
