Diameter perfect codes form a natural generalization for codes. They are based on the code-anticode bound which generalizes sphere-packing bound. The was proved by Delsarte distance-regular graphs and it holds some other metrics too. In this paper we prove non-binary constant-weight with Hamming metric characterize diameter maximum size anticodes these We distinguish between six families of fou...

there are some machineries and equipments as well as relatively fix amount of human resources involved in any production process. in many cases, by observing operational method of a process, one may see that some of these machineries are not working, but on the other hand, other equipments are continuously working, and many parts are set in front of them, waiting to be set up over machines to c...

the liquefaction resistance of soil can be evaluated using laboratory tests such as cyclic simple shear, cyclic triaxial, cyclic torsional shear as well as field methods like standard penetration test (spt), cone penetration test (cpt) and shear wave velocity (vs). in this regard, this study attempts to compare the results of the spt based on the simplified procedure proposed by seed and idriss...

We study an altruistic growth model with production uncertainty viewed as an inter-generational stochastic game. Each generation derives utility from its own consumption and consumption of all successors. The existence of stationary Markov perfect equilib-ria is proved under general assumptions on utility functions for the generations and for non-atomic transition probabilities.
