Energy-saving, punctuality and smoothness are difficult to achieve in the operation of heavy haul train.This paper proposes a multi-objective method for speed curve optimization.Firstly, a quadratic programming optimization model is established, using train kinetic energy and train Plastic Heavy Weight Cutlery force as independent variables and sev
Urban Art far beyond counterculture
Urban art emerged as a counterculture movement based on social, political and economic criticism.To shape these criticisms, interventions are made around city centers and peripheries, in the most unusual places, such as bridges, sewers, Plastic Heavy Weight Cutlery abandoned places, train stations, house walls and top of buildings.Because it is don
Deep learning approach based on superpixel segmentation assisted labeling for automatic pressure ulcer diagnosis.
A pressure ulcer is an injury of the skin and underlying tissues adjacent to a bony eminence.Patients who suffer from this disease may have difficulty accessing medical care.Recently, the COVID-19 pandemic has exacerbated this situation.Automatic diagnosis based on machine learning (ML) brings promising solutions.Traditional ML requires complicated
Application of Two Kinds of Automatic Nucleic Acid Purifiers
Objective To investigate the effect of automatic nucleic acid purifiers QIAsymphony SP and QIAcube in the DNA extraction of samples of trace amount or mixed with inhibitors.Methods Different kinds of purification methods using QIAsymphony SP and QIAcube were applied to extract swabs which contained 30, 100, 150 and 300 cells and other samples which
Canine angiostrongylosis: recent advances in diagnosis, prevention, and treatment
Angela Di Cesare, Donato Traversa Faculty of Veterinary Medicine, University of Teramo, Teramo, Italy Abstract: Angiostrongylus vasorum is a parasitic Plastic Heavy Weight Cutlery nematode affecting the heart and pulmonary arteries of wild (eg, foxes) and domestic canids.The parasite has an indirect life cycle in which slugs and snails act as inter
