  2. 1. Efficient modeling and control of crushing processes in minerals processing

    Author : Marcus Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HPGR; Comminution; Jaw crusher; Process control; Modeling; Dynamic modeling; Minerals processing;

    Abstract : Modeling and simulation is a tool to explore and increase the understanding of a phenomenon. This thesis focuses on developing models of crushers and equipment used in the mining industry. Specifically, the focus is on a branch of modeling called time dynamic modeling which is a model that gives an output as a function of time. READ MORE

  4. 2. Opportunistic Networking : Mobility Modeling and Content Distribution

    Author : Ljubica Pajevic; Gunnar Karlsson; Karin Anna Hummel; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; opportunistic networks; ad hoc networks; mobility modeling;

    Abstract : We have witnessed two main trends in recent years that have shaped the current state of communication networks. First, the Internet was designed with the initial idea to provide remote access to resources in the network; today it is overwhelmingly being used for content distribution. READ MORE

  5. 3. Measurement Based Channel Characterization and Modeling for Vehicle-to-Vehicle Communications

    Author : Taimoor Abbas; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle-to-vehicle communications; IEEE 802.11p; Channel measurements; Channel modeling; propagation modeling; MIMO; intelligent transportation systems;

    Abstract : Vehicle-to-Vehicle (V2V) communication is a challenging but fast growing technology that has potential to enhance traffic safety and efficiency. It can also provide environmental benefits in terms of reduced fuel consumption. READ MORE

  6. 4. Coding Speech for Packet Networks

    Author : Jonas Lindblom; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; packet loss concealment; voice over IP; speech coding; harmonic modeling; vector quantization; sinusoidal modeling; Gaussian mixture modeling; bounded support; frame erasure; variable dimension;

    Abstract : The topic of this thesis is speech coding for packet networks. Problems related to the use of packet networks for voice communication are addressed. Real-time voice communication is for example very delay sensitive; if the total end-to-end delay in a telephone session grows large, it is perceived as annoying. READ MORE

  7. 5. User Modeling for Adaptive Virtual Reality Experiences : Personalization from Behavioral and Physiological Time Series

    Author : Luis Quintero; Uno Fors; Lijffijt Jefrey; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; virtual reality; VR; machine learning; ML; user modeling; personalization; wearable; heart rate; HRV; biosensors; movement; behavioral; user experience; UX; spatial computing; metaverse; extended reality; XR; data- och systemvetenskap; Computer and Systems Sciences;

    Abstract : Research in human-computer interaction (HCI) has focused on designing technological systems that serve a beneficial purpose, offer intuitive interfaces, and adapt to a person's expectations, goals, and abilities. Nearly all digital services available in our daily lives have personalization capabilities, mainly due to the ubiquity of mobile devices and the progress that has been made in machine learning (ML) algorithms.
