American factory - Japanese factory [PDF]

open access: yesSocial Science Japan Journal, 2001
There are fashions in the academic world; and they come and go. In the 1980s, it was fashionable to talk about the 'miracle' of Japanese factory management in light of the successful achievement of its 'lean production' methods. Rather belatedly, the world realized that Japanese manufacturing of machinery, especially motor-vehicle production ...

Factorial formulae and computer-aided research

open access: yesLietuvos Matematikos Rinkinys, 2008
We try to demonstrate how it is possible to acquaint students with the usual computer-aided research of a mathematician.

Poly-falling factorial sequences and poly-rising factorial sequences

open access: yesOpen Mathematics, 2021
In this paper, we introduce generalizations of rising factorials and falling factorials, respectively, and study their relations with the well-known Stirling numbers, Lah numbers, and so on.

Accounting for the Role of Long Walks on Networks via a New Matrix Function [PDF]

open access: yes, 2016
We introduce a new matrix function for studying graphs and real-world networks based on a double-factorial penalization of walks between nodes in a graph. This new matrix function is based on the matrix error function.

Pyrolysis of sandbox (Hura crepitans) shell: Effect of pyrolysis parameters on biochar yield

open access: yesResearch in Agricultural Engineering, 2015
Pyrolysis of sandbox shell was carried out with the aim of investigating the effect of pyrolysis parameters on the pyrolysis process and identifies production conditions for the yield of biochar. Parameters investigated were heating temperature (400, 500

Properties of Factorial Cumulant to Factorial Moment Ratio

open access: yes, 1994
It is shown that the ratio of factorial cumulant moments to factorial moments for a multiplicity distribution truncated in the tail reveals oscillations in sign similar to those observed in experimental data.

Geometrical reasoning in the determination of the order of factorial

open access: yesLietuvos Matematikos Rinkinys, 2008
It is shown here how to interpret Stirling’s formula geometrically, moreover, how geometrical reasoning can serve determining the proper magnitude of the logarithm of the factorial.

Factorial correlators: angular scaling within QCD jets [PDF]

open access: yes, 2000
Factorial correlators measure the amount of dynamical correlation in multiplicity between two separated phase-space windows. We present the analytical derivation of factorial correlators for a QCD jet described at the double logarithmic (DL) accuracy. We

Identification of Colour Reconnection using Factorial Correlator [PDF]

open access: yes, 1999
A new signal is proposed for the colour reconnection in the hadronic decay of W+ W- in e+e- collisions. Using Pythia Monte Carlo it is shown that this signal, being based on the factorial correlator, is more sensitive than the ones using only averaged ...

Q-factorial Laurent rings

open access: yes, 2011
Dolgachev proved that, for any field k, the ring naturally associated to a generic Laurent polynomial in d variables, $d \geq 4$, is factorial. We prove a sufficient condition for the ring associated to a very general complex Laurent polynomial in d=3 ...
