On the description of a scattering medium by the number of particles scattered [PDF]

open access: possibleAstrophysics and Space Science, 1978
We find the distribution in space and time of scatterers as a function of particles scattered in a one-dimensional rod under the influence of an incident pulse. For the steady-state case we find the distribution of scatterers according to the number of particles that are being scattered.

Rotational Projection Statistics for 3D Local Surface Description and Object Recognition

International Journal of Computer Vision, 2013
Recognizing 3D objects in the presence of noise, varying mesh resolution, occlusion and clutter is a very challenging task. This paper presents a novel method named Rotational Projection Statistics (RoPS).

Service description and usage of identities/numbers for FPLMTS

Proceedings of ICUPC '95 - 4th IEEE International Conference on Universal Personal Communications, 2002
As the third generation mobile system, FPLMTS is expected to provide more service capabilities than that of existing mobile systems, especially in personal telecommunications. The Telecommunication Technology Committee (TTC) and its FPLMTS subcommittee has been studying Future Public Land Mobile Telecommunication Systems (FPLMTS).

An alternative description of systems with a finite number of states [PDF]

open access: possibleJournal of Physics A: Mathematical and General, 1990
The author shows how one can give a quantum description for systems having (2n+1)-dimensional anticommuting phase space. The Hilbert space related to these systems has 2n dimensions. Among the applications of those systems are spin in three dimensions and the d-dimensional relativistic spinning particle.

Hyperbranched polymers from A2 + B3 strategy: recent advances in description and control of fine topology

, 2016
Hyperbranched or highly branched polymers from A2 + B3 step-growth polymerization have received considerable attention as an emerging area of research due to their environmentally benign, convenient one-pot synthesis and potential for large-scale ...

Another Description of the Central Delannoy Numbers: 10894

The American Mathematical Monthly, 2003
gcd(a,b) a = aop1 ...Pk and b = bop . .. Pk, where gcd(ao, bo) = 1 and P1 ..., Pk are primes. Let al = aop ... Pi. We have lcm(aj,b) _ a0b and lcm(al, b) = aob. We gcd(al,b) Pl"'Pl conclude that a0b divides al * b and that at * b divides aob. This yields (1) by induction on 1. By (1), for each a = ?pl .

Description of MCV, a pseudo-random number generator

Scandinavian Actuarial Journal, 1976
Abstract The need for random-numbers in simulation in nuclear physics, communications, risk theory, queue systems, industrial organization and many other related and similar topics is beyond question. Sooner or later the calculation part of these problems grows beyond human powers and a computer has to be involved.

Numbers and Newness: The Descriptive and Substantive Representation of Women

Canadian Journal of Political Science, 2007
Abstract.The concept of “critical mass,” drawn from physics and organizational behaviour literatures, has been employed by women and politics scholars as a potential theoretical underpinning for explaining and predicting women's substantive representation in national legislatures.
