  1. 1. Large-scale Exploratory Text Visualisation

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Author : Wilma Axelsson; Nellie Engström; [2023]
    Keywords : Natural language processing; information visualisation; text visualisation; Swedish news articles; dynamic topic modeling; hierarchical topic modeling; BERTopic;

    Abstract : The amount of available text data has increased rapidly in the latest years, making it difficult for an everyday user to find relevant information. To solve this, NLP and visualisation methods have been developed for extracting valuable information from text and presenting it to the user. READ MORE

  3. 2. Comparing Analog and Digital Non-Linear Sonic Signatures : an Investigation on Creative Application and Subjective Perception using the Universal Audio 1176 FET Compressor

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Behzad Mehrnoosh; [2021]
    Keywords : compression; compressor; non-linear; distortion; sonic signature; analog; hardware; digital; software; emulation; modeling; 1176;

    Abstract : Historically, compression was primarily used as a preventative measure to reduce the risk of clipping or overloading equipment in the recording signal chain. Research on the topic has revealed that modern production applications more commonly include utilizing compression as a creative effect, to impart distortion, manipulate timbre, and modify transients, rather than to control the dynamic range of audio signals.

  4. 3. A system dynamic approach for manufacturing reshoring decisions.

    University essay from Jönköping University/JTH, Industriell produktutveckling, produktion och design

    Author : Daniel Alejandro de los Rios Pérez; [2021]
    Keywords : reshoring; modeling; system dynamics; manufacturing; decision-making; location decisions;

    Abstract : During the last two decades, many companies have reshored their manufacturing operations to the home country, reversing previous offshoring decisions. Reshoring is a strategic decision for manufacturing companies because it is costly, complex, dynamic; thus, it is an important topic for research. READ MORE

  5. 4. Fuel Cell Hybrid Vehicle Modeling in Modelica

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Sara Sigfridsson; [2018]
    Keywords : Technology and Engineering;

    Abstract : Exchanging classical combustion motors in cars for more environmentally friendly solutions is a hot topic worldwide and this has currently been taken to a new dimension by the release of the first hydrogen driven vehicles on the world market. The objective of this master thesis has been to develop a Modelica model of an automotive hydrogen fuel cell system, which should be integrated in an already existing vehicle system template and be simulated in various drive cycle tests.

  6. 5. Fluid Structure Interaction Modeling of the Dynamic of a Semi Submerged Buoy

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Shatha Hameed Hajwal; Hamza Zeidan Nasser; [2013]
    Keywords : COMSOL Multiphysics; wave energy converter; Dynamic characteristic; Submerged body; Finite Element method FE ; SDOF; ALE.;

    Abstract : This thesis presents a study of buoy systems for wave’s energy by focusing on the development of a model in which modeling of a wave energy conversation is in operation. Throughout the thesis, the buoyancy and motion of the submerged body has been used to describe the wave-buoy interaction. READ MORE
