Improved Learning Algorithm for Self-adaptive Neural Nets Based on Principal Component Analysistion from source cube, and gives the mathematical equation derivation for solving single and multiple principal components in multiple input and multiple output nets, puts forward the learning algorithm deduction of self-adaptive principal component feature extraction in neural network. The validity

Dual-Command Operation Generation in Bi-Directional Flow-Rack Automated Storage and Retrieval Systems with Random Storage Policy,ed from half bins and be stored to the other half on the same working face. For random storage policy, a batching-greedy heuristic (BGH) has been proposed to generate dual-command (DC) operations in BFR AS/RS. In this paper, a novel DC operation generation rule specially designed for the BFR AS/RS i

Benign Epithelial Tumors and Hamartomas of the Biliary Tract,lary adenomas, sometimes with a villous configuration, occur in the extrahepatic ducts. These lesions can present as solitary neoplasms, but also develop in the form of numerous lesions involving large parts of the biliary. The latter condition was previously termed biliary papillomatosis. Its relat

Equivalence between Extended Datalog Programs — A Brief Surveyform equivalence. Most notably, uniform equivalence becomes undecidable in the presence of default negation, while strong equivalence remains decidable for full disjunctive datalog. We also consider a restricted setting where the arity of predicates is bounded by a fixed constant.

Writing, Chronology and Themes,ogical treatment is based on three groups: a nitric oxide donor (glyceryl trinitrate), calcium channel antagonists (diltiazem, nifedipine), and botulinum toxin. The results of these treatments are better than placebo but inferior to surgery. If these treatments fail, surgery is the best option. Sphi
