RELATIVITY GROUPOID INSTEAD OF RELATIVITY GROUP [PDF]
International Journal of Geometric Methods in Modern Physics, 2007 In 1908, Minkowski [13] used space-like binary velocity-field of a medium, relative to an observer. In 1974, Hestenes introduced, within a Clifford algebra, an axiomatic binary relative velocity as a Minkowski bivector [7, 8]. We propose to consider binary relative velocity as a traceless nilpotent endomorphism in an operator algebra. Any concept of a

Attention-Based Lightweight YOLOv8 Underwater Target Recognition Algorithm
SensorsUnderwater object detection is highly complex and requires a high speed and accuracy. In this paper, an underwater target detection model based on YOLOv8 (SPSM-YOLOv8) is proposed. It solves the problems of high computational complexities, slow detection

Knowability Relative to Information [PDF]
, 2018 We present a formal semantics for epistemic logic, capturing the notion of knowability relative to information (KRI). Like Dretske, we move from the platitude that what an agent can know depends on her (empirical) information.

Relative Odds of Neck Pain to Helmet Use Among Motorcyclists: a Case-Control Study [PDF]
, 2020 Background: Neck pain is a widespread problem among motorcyclists, which is often neglected. There is limited research on the motorcycle's ergonomics, particularly in the context of the interaction between the riders and motorcycle.

Space and Time as Relations: The Theoretical Approach of Leibniz
Philosophies, 2018 The epistemological rupture of Copernicus, the laws of planetary motions of Kepler, the comprehensive physical observations of Galileo and Huygens, the conception of relativity, and the physical theory of Newton were components of an extremely fertile ...

, 2005 This paper introduces the notion of ``relative gerbes'' for smooth maps of manifolds, and discusses their differential geometry. The equivalence classes of relative gerbes are further classified by the relative integral cohomology in degree ...

, 2014 We introduce a relative fixed point property for subgroups of a locally compact group, which we call relative amenability. It is a priori weaker than amenability.

A new method for efficacy testing of control measures against adult Western Corn Rootworm in maize
Journal für Kulturpflanzen, 2012 Relative sampling methods, like sticky traps, are commonly used to monitor population fluctuations of flying insects, either to facilitate control decisions in integrated pest management or for evaluation of experimental insecticide treatments in ...
