Production Matrices

چکیده
We translate the concept of succession rule and the ECO method into matrix notation, introducing the concept of a production matrix. Among other things, this allows us to combine our method with other enumeration techniques using matrices, such as the method of Riordan matrices. Moreover, we show that certain operations on production matrices correspond to well known operations on the numerical sequences determined by them. Nous transférons l’idée de règle de succession et la mèthode ECO dans la notation des matrices, en introduisant l’idée de matrice de production. Entre autres choses, ça nous a permis de concilier notre méthode avec d’autres techniques d’énumération qui utilisent des matrices, comme la méthode des matrices de Riordan. En autre, nous montrons que certaines opérations sur les matrices de production correspondent à des opérations bien connues sur les séquences numériques qu’elles déterminant.

In selection index procedure, phenotype and genetic (co)variance matrices of traits are used for calculating different genetic parameters like index coefficients, index variance, genetic gain in selection goal and selection accuracy. Sometimes, it is possible that these matrices become inconsistent or they are not positive, nor definite. In the current study, for investigation of the effect of ...

Objective Eudragits are widely used polymers in the production of oral sustained release dosage forms. The application of these polymers in the production of inert insoluble matrices has been investigated. However the effect of particle size, compaction force and presence of Aerosil 200 as a glidant on the properties of Eudragit RS and RL matrices prepared by direct compression of their physic...

Production of aluminum matrix composites is widespread because these material provide enhanced mechanical properties compared to aluminum. One the most important parameters of metal matrix composite production is uniform distribution of reinforcing nanoparticles in matrices using the stir-casting method. Second is ensuring high wettability, which is determined by evaluating the properties of ma...
متن کاملParametric Production Matrices and Weighted Succession Rules: a Dyck Path Example
We introduce weighted succession rules and parametric production matrices — simple extensions of the standard ECO method succession rules and production matrices. The purpose is to enumerate combinatorial objects with respect to several variables. We consider one main example, from the theory of Dyck paths. The path statistics primarily considered are peak height, rise height, and certain subwa...
