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

    Författare :Luis Quintero; Uno Fors; Lijffijt Jefrey; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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.

  3. 2. Behavioral Modeling of Radio Frequency Transmitters

    Författare :Ali Soltani Tehrani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Behavioral modeling; wireless communications; I Q imbalance; computational complexity; nonlinear models; Volterra series; transmitter; power amplifier; digital predistortion;

    Sammanfattning : The dependence of modern wireless communication systems on the fidelity ofthe transmitter has increased the importance of modeling these components.Behavioral modeling is a commonly used technique to find the input-outputrelationship of a system, without the need for the knowledge of the specificcomponents.

  4. 3. Behavioral modeling of wireless transmitters for distortion mitigation

    Författare :Ali Soltani Tehrani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear models; wireless communications.; computational complexity; I Q imbalance; digital predistortion; Volterra series; transmitter; power amplifier; Behavioral modeling;

    Sammanfattning : As the demand for high speed and reliable wireless communication increases, theimportance of having a linear transmitter has enhanced. Distortions created by thetransmitter, such as power amplifier nonlinearity and I/Q imbalance, diminish thefidelity and limit the performance of wireless systems, if left undealt with. LÄS MER

  5. 4. Formal Approaches to Service-oriented Design : From Behavioral Modeling to Service Analysis

    Författare :Aida Čaušević; Paul Pettersson; Jonathan P. Bowen; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; service-oriented software engineering; formal modeling; service-oriented systems; resources; analysis; behavior; correctness check; Computer science; Datavetenskap; Computer Science; datavetenskap;

    Sammanfattning : Service-oriented systems (SOS) have recently emerged as context-independent component-based systems. In contrast to components, services can be created, invoked, composed and destroyed at run-time. Services are assumed to be platform independent and available for use within heterogeneous applications. LÄS MER

  7. 5. On Radio Frequency Behavioral Modeling : Measurement Techniques, Devices and Validation Aspects

    Författare :Per N. Landin; Peter Händel; Magnus Isaksson; Wendy Van Moer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Elektronik;

    Sammanfattning : Effektförstärkare för radiofrekvensapplikationer utgör fortfarande ett av de största problemen i trådlösa kommunikationssystem. Detta beror på att dessa förstärkare är ickelinjära, har låg energieffektivitet och ger mycket distortioner. Bättre verktyg för att förstå och korrigera dessa beteenden är nödvändiga. LÄS MER
