  1. 1. Functional modelling of the human timing mechanism

    Författare :Guy Madison; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Brain mechanisms; Brownian motion; drift; dynamical systems; fractal; human; Gaussian noise; Hurst exponent; time; time series analysis; timing; Psykologi; Psychology; Psykologi; fysiologi; Physiology;

    Sammanfattning : Behaviour occurs in time, and precise timing in the range of seconds and fractions of seconds is for most living organisms necessary for successful interaction with the environment. Our ability to time discrete actions and to predict events on the basis of prior events indicates the existence of an internal timing mechanism. LÄS MER

  2. 2. It's complicated: : The role of timing in microbial community coalescence

    Författare :Theresa Lumpi; Eva S. Lindström; Clara Ruiz-González; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; community coalescence; arrival timing; dispersal timing; microbial communities; community composition; lake bacteria; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Sammanfattning : In recent years, the importance of historical contingency has been increasingly recognized in microbial communities. During community coalescence, immigration history, and dispersal history can become decisive for the developing community. LÄS MER

  3. 3. Effect of timing training in golf and soccer players : skill, movement organization, and brain activity

    Författare :Marius Sommer; Louise Rönnqvist; Charlotte Häger; Nicola Hodges; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Motor timing; rhythmicity; timing training; golf shot; golf swing; kinematics; precision; variability; coordination; movement dynamics; soccer; fMRI; mirror neurons; action observation; cerebellum; perception - action.; Psychology; psykologi;

    Sammanfattning : Background Although trainers and athletes consider ‘good timing skills’ to be critical for optimal sport performance, little is known in regard to how sport-specific skills may benefit from timing training. Thus, assuming that all motor performances are mediated by an internal timing mechanism, enhanced motor timing is expected to have positive effects on both planning and execution of movement performance, and consequently on complex sports actions as golf or soccer.

  4. 4. Securing functional programs with floating-label information-flow control

    Författare :Pablo Buiras; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; covert timing channels; LIO; concurrency; type-level programming; floating-label; Haskell; internal timing; dynamic enforcement; DC labels; dynamic policies; lazy evaluation; information-flow control; cache-based attacks; language-based security; hybrid enforcement; flow-sensitivity; functional programming; privileges;

    Sammanfattning : The work presented in this thesis focuses on information-flow control systems for functional programs, particularly on the LIO library in Haskell. The thesis considers threemain aspects in this area: timing covert channels, dynamic policies andenforcement mechanisms that improve precision of the analysis. LÄS MER

  5. 5. Language Support for Controlling Timing-Based Covert Channels

    Författare :Alejandro Russo; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; information-flow; language-based security; semaphores; non-interference; Haskell; library; concurrency; internal timing covert channel;

    Sammanfattning : The problem of controlling information flow in multithreaded programs remains an important open challenge.A major difficulty for tracking information flow in concurrent programs is due to the internal timing covert channel. LÄS MER
