  1. 11. Towards Large-Capacity and Cost-Effective Main Memories

    Författare :Dmitry Knyaginin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fairness; Energy Efficiency; Hybrid Main Memory; Performance; Design-Space Exploration; Parallel Memory Protocols; Large-Capacity Local Memory; Hardware-Based Hybrid Memory Management; Cost-Effectiveness;

    Sammanfattning : Large, multi-terabyte main memories per processor socket are instrumental to address the continuously growing performance demands of domains like high-performance computing, databases, and big data. It is an important objective to design large-capacity main memories in a way that maximizes their cost-effectiveness and at the same time minimizes performance losses caused by cost-effective tradeoffs.

  3. 12. Memories of traumatic events among swedish police officers

    Författare :Ingemar Karlsson; Sven Å Christianson; Pekka Santtila; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Trauma; Memory; Police officers; Eyewitnesses; Psychology; Psykologi;

    Sammanfattning : Police officers run a risk of exposure to extremely stressful and traumatic situations in their work. Such situations may involve anything from being the first to arrive at the scene of a traffic accident to investigations of brutal murders or acute threat situations in which they themselves are forced to use force.

  4. 13. Low Power Techniques for Fast CMOS Buffer Memories

    Författare :Jonas Alowersson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Systems engineering; low-power; throughput; buffer memory; CMOS; SRAM; computer technology; Data- och systemvetenskap;

    Sammanfattning : The thesis deals with circuit-level aspects of CMOS buffer SRAMs where the data throughput rate is a more important metric than access time or storage capacity. One aspect is the increased write cycle related power consumption that is the consequence of a high write ratio combined with a long word-length. LÄS MER

  5. 14. Optical Memories and Processing in Time- and Frequency Domain

    Författare :Baozhu Luo; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical storage; photon echo; spectral hole burning; nonlinear optics; fiber amplifier; logical operation; phase retrieval; polarization holographic recording and retrieval; optical processing; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:1998:Luo;

    Sammanfattning : Spectral hole burning and photon echoes are the techniques for frequency-selective optical memories, which have the potential to increase areal data storage density by a factor 10**7. They also have the capability to perform in-memory data processing. LÄS MER

  7. 15. Emotional mental imagery and the reduction of fear within the mind’s eye

    Författare :Johanna M. Hoppe; Thomas Ågren; Emily A. Holmes; Francisco Estevez; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mental imagery; emotion; imaginal exposure; imaginal extinction; hotspots; intrusive memories; Psychology; Psykologi;

    Sammanfattning : Mental imagery refers to sensory-perceptual experiences in the absence of external sensory input. Emotional mental imagery (i.e., imagery with emotional content) is a key feature in many mental disorders, such as the image-based intrusive memories of trauma in posttraumatic stress disorder (PTSD).
