Analytical theory of pyrochlore cooperative paramagnets

Comparative –Analytical Study of Economic Productivity of Water between Smallholding and Rural Production Cooperative Utilization System

In recent years, farming section of South Khorasan Province faces different limitations such as increasing shortage of water resources and continuous reduction of weather showers.Considering consecutive droughts and water crisis in agricultural plain of the province, it is necessary to use water resources optimally and increase productivity of water shortage input. Comparison of water productiv...

Quantum Correlation Functions of 1-Dimensional Paramagnets

We calculate hydrodynamic mode longitudinal and transverse spin correlation functions for polarized quantum one­dimensional lattices containing two, four, and eight spins using a Heisenberg nearest neighbor interaction. We also analyze the spectra of these systems. INTRODUCTION Recently, Cowan and Mullin[1] have used a moments method to study spin transport in polarized paramagnetic (high tempe...

Transmission cost allocation based on cooperative game theory

Cooperative aggregate production planning: a game theory approach

Production costs in general, and workforce and inventory costs in particular, constitute a large fraction of the operating costs of many manufacturing plants. We introduce cooperative aggregate production planning as a way to decrease these costs. That is, when production planning of two or more facilities (plants) is integrated, they can interchange workforce and products inventory; thus, thei...

Cooperation theory of cooperative breeding.

Cooperative breeding is the joint raising of offspring by wo or more individuals, where at least one of them is not he genetic parent of the young. The key characteristics of ooperative breeding systems are diversity of social behaviours ithin and between groups and high variation of factors influncing conflict over reproduction (for review see Komdeur, 006). In the second half of the 20th cent...
