New Approach to the Theory of Numbers - Prime Numbers

Authors: Fortuné Alain Junior BACKOULAS
Comments: 82 Pages. We recall that this document is in French, an English version will be published shortly

This document contains new methods and tools that allow us to have a new vision on the theory of numbers. Including understanding of prime numbers. New highly detailed methods have been developed in this paper and thus help to understand how the primes whose mystery has fascinated interacting in the set of integers. We are sure that the logic we use here will bring more light to the theory of numbers and that has certainly been understood before. We invite you to read this

The Riemann Hypothesis.

Authors: Cristian Dumitrescu
Comments: 9 Pages.

In this article I describe a proof of the fact that ZFC cannot decide whether a certain modified Turing machine, or computer (satisfying a certain condition) will ever halt successfully in finite time. The consequences of this fact in relation to the Riemann Hypothesis are presented.

Few Types of Chains of Primes Arising in the Study of Pseudoprimes

Authors: Marius Coman
Comments: 4 Pages.

While studying Fermat pseudoprimes I met few interesting generic forms of numbers that have the property to generate chains of primes and pseudoprimes. I list in this paper few such types of chains.

Formulas that Generate Subsets of 3-Poulet Numbers and Few Types of Chains of Primes

Authors: Marius Coman
Comments: 3 Pages.

A simple list of sequences of products of three numbers, many of them, if not all of them, having probably an infinity of terms that are Fermat pseudoprimes to base 2 with three prime factors.

Extended Midy's Theorem

Authors: Bassam Abdul-Baki
Comments: 5 Pages.

In mathematics, Midy's theorem, named after French mathematician E. Midy, is a statement about the decimal expansion of fractions a/p where p is a prime and a/p has a repeating decimal expansion with an even period. If the period of the decimal representation of a/p is 2n, then the digits in the second half of the repeating decimal period are the 9s complement of the corresponding digits in its first half. The Extended Midy's Theorem states that if the repeating portion of the decimal expansion of a/p is divided into k-digit numbers, then their sum is a multiple of 10^k − 1.

A List of 13 Sequences of Carmichael Numbers Based on the Multiples of the Number 30

Authors: Marius Coman
Comments: 4 Pages.

The applications of the multiples of the number 30 in the study of Fermat pseudoprimes was for a long time one of my favourite subject of study; in this paper I shall list 13 sequences that I discovered, many of them, if not all of them, having probably an infinity of terms that are Carmichael numbers. I posted many of them on OEIS, where I analized more of their attributes; here I’ll just list them, enumerate their first few terms and present few conjectures.

Simulation of Flexible Manufacturing System (FMS) using Fuzzy Logic

Authors: Ziaul Hassan Serneabat, Nabila Chowdhury, A.K.M. Masud
Comments: 13 Pages.

This paper focuses on the simulation of the flexible manufacturing system. Flexible manufacturing systems (FMS) are production systems consisting of identical multipurpose numerically controlled machines (workstations), automated material handling system, tools, load and unload stations, inspection stations, storage areas and a hierarchical control system. The model will prioritize the job and select the best alternative route with multi-criteria scheduling through an approach based on a fuzzy logic. There are three criteria for both the job sequencing and routing with 27 rules. With the help of the rules the sequence of the jobs are done and the best route is selected.
