Applications of design theory for the constructions of MDS matrices for lightweight cryptography

Journal of Mathematical Cryptology, 2017
In this paper, we observe simple yet subtle interconnections among design theory, coding theory and cryptography. Maximum distance separable (MDS) matrices have applications not only in coding theory but are also of great importance in the design of ...

Effects of xylanase and antibiotic supplementations on the nutritional utilisation of a wheat diet in growing chicks from genetic D+ and D− lines selected for divergent digestion efficiency

Animal, 2007
The experiment consisted of a 2 × 2 × 2 factorial design testing the two D+ and D− chicken lines selected for divergent digestion efficiency (fifth selection generation), xylanase (with or without) and ampicillin and collistin (with or without ...

Low-power and area-efficient memristor based non-volatile D latch and flip-flop: Design and analysis.

PLoS ONE
In recent years, non-volatile memory elements have become highly appealing for memory applications to implement a new class of storage memory that could replace flash memories in sequential logic applications, with features such as compactness, low power,

Time-Efficient and Practical Design Method for Skewed PMSMs: Integrating Numerical Calculations With Limited 3-D-FEA

IEEE Open Journal of the Industrial Electronics Society
This article proposes a time-efficient and practical design method for determining appropriate skew structures for permanent magnet synchronous motors (PMSMs). Various PMSMs use skew to suppress torque ripple, but 3-D finite element analysis (3-D-FEA) is

Determinant Efficiencies in Ill-Conditioned Models

Journal of Probability and Statistics, 2011
The canonical correlations between subsets of OLS estimators are identified with design linkage parameters between their regressors. Known collinearity indices are extended to encompass angles between each regressor vector and remaining vectors. One such

Optimal Input Signal Design for a Second Order Dynamic System Identification Subject to D-Efficiency Constraints

, 2015
System identification, in practice, is carried out by perturbing processes or plants under operation. That is why in many industrial applications an optimal input signal would be preferred for system identification. In this case, the objective function was formulated through maximisation of the Fisher information matrix determinant (D-optimality ...

D-orbital Reconstruction Achieves Low Charge Overpotential in Li-oxygen Batteries

Nature Communications
Charge overpotential for oxygen evolution reaction is a crucial parameter for the energy conversion efficiency of lithium-oxygen (Li-O2) batteries. So far, the realization of low charge overpotential via catalyst design is a grand challenge in this field,
