Investigation of Importancgweighted Infinite Multiplication Constants in Clean and Poisoned Lwhc” Lattices
نویسنده
چکیده
The experimental procedures for obtaining importance-weighted k, values in clean and B.,C-poisoned ,LWHCR test lattices with different simulated moderator voidage states are described. The results of these measurements, presented as calculation/experiment values, are interpreted in two different ways, viz. in terms of the reactivity effect of BaC as control absorber and the effect of poison on the moderator void coefficient. The current experiments represent a significant broadening of the integral data base’~being enerated in the PROTEUS-LWHCR Phase II program. Viewed in conjunction with the reaction rate ratio measurements performed in the clean lattices, they have revealed important deficiencies in the standard methods/data commonly applied in LWHCR design.

Topological Residuated Lattices
In this paper, we study the separtion axioms $T_0,T_1,T_2$ and $T_{5/2}$ on topological and semitopological residuated lattices and we show that they are equivalent on topological residuated lattices. Then we prove that for every infinite cardinal number $alpha$, there exists at least one nontrivial Hausdorff topological residuated lattice of cardinality $alpha$. In the follows, we obtain some ...
متن کاملAn equivalence functor between local vector lattices and vector lattices
We call a local vector lattice any vector lattice with a distinguished positive strong unit and having exactly one maximal ideal (its radical). We provide a short study of local vector lattices. In this regards, some characterizations of local vector lattices are given. For instance, we prove that a vector lattice with a distinguished strong unit is local if and only if it is clean with non no-...
متن کاملInclusions and non-inclusions of Archimedean and Laves lattices
For each pair of graphs from among the Archimedean lattices and their dual Laves lattices we demonstrate that one is a subgraph of the other or prove that neither can be a subgraph of the other. Therefore, we determine the entire partial ordering by inclusion of these 19 infinite periodic graphs. There are a total of 72 inclusion relationships, of which 35 are covering relations in the partial ...
متن کاملWiener Way to Dimensionality
This note introduces a new general conjecture correlating the dimensionality dT of an infinite lattice with N nodes to the asymptotic value of its Wiener Index W(N). In the limit of large N the general asymptotic behavior W(N)≈Ns is proposed, where the exponent s and dT are related by the conjectured formula s=2+1/dT allowing a new definition of dimensionality dW=(s-2)-1. Being related to the t...
متن کاملA degree bound for the Graver basis of non-saturated lattices
Let $L$ be a lattice in $ZZ^n$ of dimension $m$. We prove that there exist integer constants $D$ and $M$ which are basis-independent such that the total degree of any Graver element of $L$ is not greater than $m(n-m+1)MD$. The case $M=1$ occurs precisely when $L$ is saturated, and in this case the bound is a reformulation of a well-known bound given by several authors. As a corollary, we show t...
