  2. 1. LSB Data Hiding in 360o Videos

    Author : Dang Ninh Tran; Hans-Jürgen Zepernick; Thanh Nguyen Huu; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LSB data hiding; 360° Videos; Capacity; Fidelity; Quality; Computer Science; Datavetenskap; Telekommunikationssystem; Telecommunication Systems;

    Abstract : Modern telecommunication systems have seen an increased demand on delivering new types of digital media such as extended reality. The currently rolled out fifth generation mobile networks are expected to support virtual reality, augmented reality, and other immersive media. READ MORE

  4. 2. Functional characterization of the secretory pathway and the role of COPI vesicles

    Author : Johan Hiding; Göteborgs universitet; []
    Keywords : Golgi; Phosphoinositides; Fusion; COPI; ARF1; Proteomics; ER;

    Abstract : In the secretory pathway, proteins synthesized in the endoplasmatic reticulum move through the Golgi apparatus in a cis-to-trans direction and then sorts into different types of vesicles at the trans-Golgi network. How intracellular transport takes place has been the focus of cell biology research for a long time. READ MORE

  5. 3. Hiding and Reducing Memory Latency : Energy-Efficient Pipeline and Memory System Techniques

    Author : Andreas Sembrant; David Black-Schaffer; Erik Hagersten; David A. Wood; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datavetenskap;

    Abstract : Memory accesses in modern processors are both far slower and vastly more energy-expensive than the actual computations. To improve performance, processors spend a significant amount of energy and resources trying to hide and reduce the memory latency. READ MORE

  6. 4. Anonymizing Faces without Destroying Information

    Author : Felix Rosberg; Cristofer Englund; Eren Aksoy; Fernando Alonso-Fernandez; Vitomir Struc; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anonymization; Data Privacy; Generative AI; Reconstruction Attacks; Deep Fakes; Facial Recognition; Identity Tracking; Biometrics;

    Abstract : Anonymization is a broad term. Meaning that personal data, or rather data that identifies a person, is redacted or obscured. In the context of video and image data, the most palpable information is the face. Faces barely change compared to other aspect of a person, such as cloths, and we as people already have a strong sense of recognizing faces. READ MORE

  7. 5. An Automated and Controlled Numerical Precision Reduction Framework for GPUs

    Author : Alexandra Angerd; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microarchitecture; Floating-Point Precision; Approximate Computing; Register File; GPU;

    Abstract : Reducing the precision of floating-point values is an effective approach to achieve higher performance as well as higher energy-efficiency. This is especially true for GPUs, since many of its common tasks are inherently insensitive to precision-reduction. READ MORE
