Nondegenerate geometry (T-geometry) with nonsymmetric world function is considered. In application to the space-time geometry the asymmetry of world function means that the past and the future are not equivalent geometrically. T-geometry is described in terms of finite point subspaces and world function between pairs of points of these subsets, i.e. in the language which is immanent to geometry...

Information retrieval, IR, the science of extracting information from any potential source, can be viewed in a number of ways: logical, probabilistic and vector space models are some of the most important. In this book, the author, one of the leading researchers in the area, shows how these views can be reforged in the same framework used to formulate the general principles of quantum mechanics...

We propose a simple and direct method for measuring the first-order mass moment of a human body segment. With the proposed method, the first-order mass moment of the body segment can be directly measured by using only one precision scale and one digital camera. In the dummy mass experiment, the relative standard uncertainty of a single set of measurements of the first-order mass moment is estim...

Classical model Sdc of Dirac particle SD is constructed. SD is the dynamic system described by the Dirac equation. Its classical analog Sdc is described by a system of ordinary differential equations, containing the quantum constant h̄ as a parameter. Dynamic equations for Sdc are determined by the Dirac equation uniquely. Both dynamic systems SD and Sdc appear to be nonrelativistic. One succeed...

Classical model SDcl of the Dirac particle SD is constructed. SD is the dynamic system described by the Dirac equation. For investigation of SD and construction of SDcl one uses a new dynamic method: dynamic disquantization. This relativistic purely dynamic procedure does not use principles of quantum mechanics. The obtained classical analog SDcl is described by a system of ordinary differentia...

Innovative Laboratory Design 1 1 3 Advances in several technologies have created an educational opportunity for curricular innovation in physics. Experiments with correlated photons can be used in the upper-level physics curriculum to complement the teaching of an otherwise theoretical topic: quantum mechanics. Undergraduates can now recreate, on a tabletop setup, experiments with correlated ph...

The uncertainty principle is one of the fundamental principles of quantum mechanics . While studying quantum mechanics recently, the author made an exciting mathematical discovery about the product of two expectation values. The author explains the discovery. Sec. I . Introduction In quantum mechanics there is no such concept as the path of a particle. This forms the content of what is called t...

A field experiment was conducted during the seasons of 2010/2011 in a semiarid savannah zone, at the faculty of agriculture demonstration farm University of Zalingei two kilometers east of Zalingei town Western Darfur State. The aim of the experiment is to study the effect of weed control on growth and seed production of (Clitoria ternatea) under rainfed conditions. Four treatments viz.; No wee...

0. Introduction In developing generative theories of syntax the challenge has long been to reconcile two opposite kinds of empirical evidence. On the one hand, there is substantial evidence that languages of the world are deeply similar; on the other, there is also substantial evidence that they differ on the surface. For example, there are languages which allow sentences without a pronounced s...

Unconditionally secure two-party bit commitment based solely on the principles of quantum mechanics (without exploiting special relativistic signalling constraints, or principles of general relativity or thermodynamics) has been shown to be impossible, but the claim is repeatedly challenged. The quantum bit commitment theorem is reviewed here and the central conceptual point, that an ‘EinsteinP...
