3. Self-reciprocal and self-conjugate-reciprocal irreducible factors of $x^n-\lambda$ and their applications

Subjects
Computer Science - Information Theory
Abstract

In this paper, we present some necessary and sufficient conditions under which an irreducible polynomial is self-reciprocal (SR) or self-conjugate-reciprocal (SCR). By these characterizations, we obtain some enumeration formulas of SR and SCR irreducible factors of $x^n-\lambda$, $\lambda\in \Bbb F_q^*$, over $\Bbb F_q$, which are just open questions posed by Boripan {\em et al} (2019). We also count the numbers of Euclidean and Hermitian LCD constacyclic codes and show some well-known results on Euclidean and Hermitian self-dual constacyclic codes in a simple and direct way., Comment: 14 pages.

Abstract

Let $\Bbb F_q$ be a finite field with $q$ elements and $n$ a positive integer. Mart\'inez, Vergara and Oliveira \cite{MVO} explicitly factorized $x^{n} - 1$ over $\Bbb F_q$ under the condition of $rad(n)|(q-1)$. In this paper, suppose that $rad(n)\nmid (q-1)$ and $rad(n)|(q^w-1)$, where $w$ is a prime, we explicitly factorize $x^{n}-1$ into irreducible factors in $\Bbb F_q[x]$ and count the number of its irreducible factors.

26. Prediction of FV520B Steel Flow Stresses at High Temperature and Strain Rates

Abstract

In order to develop reliable constitutive equations for the simulation, the hot deformation behavior of FV520B steel was investigated through isothermal compression tests in a wide range of temperatures from 900 °C to 1100 °C at an interval of 50 °C and strain rate from 0.01 to 10 s−1 on Gleeble-1500D simulator. The effects of temperature and strain rate on deformation behavior were represented by Zener-Holloman parameter in an exponent-type equation of Arrhenius constitutive. The influence of strain was incorporated in the constitutive analysis by material constants expressed as a polynomial function of strain. The constitutive equation (considering the compensation of strain) could precisely predict the flow stress only at strain rate 0.01 s−1 except at the temperatures of 900 °C and 1000 °C, whereas the flow stress predicted by a modified equation (incorporating both the strain and strain rate) demonstrated a well agreement with the experimental data throughout the entire range of temperatures and strain rates. Correlation coefficient (R) of 0.988 and average absolute relative error (AARE) of 5.7% verified the validity of developed equation from statistical analysis, which further confirmed that the modified constitutive equation could accurately predict the flow stress of FV520B steel.

Abstract

For the precision shear of bars, the kind of rotating high-speed precision cutting method has been given. The structure design of rotary precision shearing machine and the structure design of feeding structure are completed. The method of numerical simulation is used to optimize the cutting tool, and then the experiment platform is completed. Rotary impact and the stress concentration effect of the surface of the bar are used in the paper. The experiment is carried out for the Φ8 mm diameter stainless steel bar stock by changing the speed of the cutting tool through the converter and controlling rod feeding efficiency. The experimental results show that the method is feasible to meet the requirement of various material of the small diameter rod in the industry.

Abstract

Mechanical and electrical integration is an important direction for future development of the industry. There are many products in hydraulic filed. By connecting electrical and mechanical, we can obtain more precise displacement, velocity and force of controlled object. The simulation can reduct the model and evaluate the performance of the controlled system. The overall development time and costs saved. The aim of the paper is to build a model of cartridge proportional flow valve with LMS Imagine.lab -AMESim and validate the accuracy of the built model by comparing with products catalogue.

44. Random properties of the highest level sequences of primitive sequences over [[Z.sub.[2.sup.e]]

Abstract

Using the estimates of the exponential sums over Galois rings, we discuss the random properties of the highest level sequences [a.sub.e-1] of primitive sequences generated by a primitive polynomial of degree n over [Z.sub.[2.sup.e]]. First we obtain an estimate of 0, 1 distribution in one period of [a.sub.e-1]. On the other hand, we give an estimate of the absolute value of the autocorrelation function |[C.sub.N] (h)| of [a.sub.e-1], which is less than [2.sup.e-1] ([2.sup.e-1] - 1) [square root of (3 [2.sup.2e] - 1)) [2.sup.n/2] + 2.sup.e-1] for h [not equal to] 0. Both results show that the larger n is, the more random [a.sub.e-1] will be. Index Terms--0, 1 distribution, autocorrelation function, exponential sum over Galois ring, highest level sequence, primitive sequence.
