New Journal of Physics, 2004 The simplest, `standard' model of Big Bang Nucleosynthesis (SBBN) assumes three light neutrinos (N_nu = 3) and no significant electron neutrino asymmetry, leaving only one adjustable parameter: the baryon to photon ratio eta.

Taking a look at small-scale pedestrians and occluded pedestrians [PDF]
IEEE Transactions on Image Processing, 2019 Small-scale pedestrian detection and occluded pedestrian detection are two challenging tasks. However, most state-of-the-art methods merely handle one single task each time, thus giving rise to relatively poor performance when the two tasks, in practice,

ANALYSIS OF PEDESTRIAN BEHAVIOR AT CROSSWALKS AND EVALUATION OF FUNCTIONING PEDESTRIAN CROSSINGS [PDF]
Transport Problems, 2021 Every year, on Polish roads, many deaths occur. In the best case scenario, only the vehicle is damaged. The number of road accidents is extremely high.

Dynamics and causes of crashes on Lithuanian roads
Mokslas: Lietuvos Ateitis, 2023 Lithuania is the only European Union country that has reduced the number of road deaths by more than 50% from 2011 to 2021. However, even with significant progress, Lithuania has 53 deaths per 1 million inhabitants and Lithuania is still behind the EU ...

Unfreezing autonomous vehicles with game theory, proxemics, and trust
Frontiers in Computer Science, 2022 Recent years have witnessed the rapid deployment of robotic systems in public places such as roads, pavements, workplaces and care homes. Robot navigation in environments with static objects is largely solved, but navigating around humans in dynamic ...

Leptogenesis for pedestrians [PDF]
Annals of Physics, 2005 During the process of thermal leptogenesis temperature decreases by about one order of magnitude while the baryon asymmetry is generated. We present an analytical description of this process so that the dependence on the neutrino mass parameters becomes transparent.

An IF-RCNN Algorithm for Pedestrian Detection in Pedestrian Tunnels [PDF]
IEEE Access, 2020 Para hacer frente a los problemas de mezcla de fondo, desenfoque de peatones y multiescala de peatones en túneles peatonales, propusimos un método mejorado de detección de peatones de red neuronal de convolución basada en regiones más rápidas (IF-RCNN), que utiliza Deep CNN para extraer automáticamente características de imágenes en lugar de ...
