Aiming at the effect of railway parameters on wheel wear of locomotive, VIT D3 LIQUID D20E type diesel locomotive dynamics model was built by SIMPACK software.A model combined locomotive dynamics, FASTSIM algorithm and Zobory profile wear model was built, and wheel tread wear simulation program was developed.The effect of railway parametes on wheel
Abstract Furthering our knowledge of the skin microbiome is essential to understand health and disease in canines.To date, studies into the canine skin microbiome have focused on 16S rRNA BATH SALT high throughput sequencing however, these lack the granularity of species and strain level taxonomic characterisation and their associated functions.The
This paper investigates the problem of global exponential tracking control for switched nonlinear systems with linear uncertain parameters and without persistency of excitation.A switched model reference adaptive control technique, using the mode-dependent average dwell time method and a concurrent learning approach, is proposed for the first time.
Sustainable development in urban areas is at the core of the implementation of the UN 2030 Agenda and the Sustainable Development Goals (SDG).Analysis of SDG indicator 11.3.1—Land-use efficiency based on functional urban boundaries—provides a globally harmonized avenue for tracking changes in urban settlements in different areas.In this study,
The formation of an internal fistula between Tin Sign the biliary system and the gastrointestinal tract is a rare condition with various etiologies, predominantly associated with recurrent chronic inflammation of the biliary system and tumors.Patients with this condition may lack specific clinical manifestations, presenting with symptoms such as ab
