The Naval Civil Engineering Laboratory has conducted a study of the potential applications of isotopic devices and techniques within the Naval Shore Establishment. Radiation characteristics, general applications of isotopic devices, and specific problem areas are discussed. Recommendations are included for the use of surface density and moisture gages in the inspection of compacted earth, and f...

In recent years, e-commerce shopping festivals based on the presale model have become increasingly popular. Under pre-sale model, some companies used inventory front-loading methods to give consumers higher time satisfaction for alleviating pressure caused by order piling. At same a new return method has been generated, but existing studies only considered traditional method. this paper, dualob...

The Nara Bladder Tumor No. 2 cell line, established from a urinary bladder carcinoma in the Wistar rat, formed keratinizing cells and multicellular pearls in meniscus gradient culture when fed with a medium of 15 or 30% fetal calf serum in Eagle's minimal essential medium. Confluent monolayer cultures were first prepared with the tubes in conventional horizontal position. When cultures were the...

Optimization algorithms are iterative procedures that evolve from guessed starting points (SP) to the desired global minimum. Their performance can be greatly improved [1], if a neural network (NN) is created to select suitable SP. Here, we have trained NN’s to select possible groundstate geometries for silicon clusters. A genetic algorithm uses these candidates as initial population and perfor...
