RESEARCH ON OPTIMIZATION OF TEMPERATURE SENSITIVE POINTS OF MACHINE TOOL THERMAL ERROR BASED ON INDEPENDENT VARIABLE SELECTION CRITERIA

Research on optimization of temperature sensitive points of machine tool thermal error based on independent variable selection criteria

Abstract In order to improve the prediction accuracy and Energy Drinks robustness of the machine tool thermal error model, a method to select temperature sensitive points of the machine tool thermal error model based on independent variable selection criteria is proposed.Firstly, the positioning error of the machine tool is divided into geometric p

Transcriptome analysis of antioxidant system response in Styrax tonkinensis seedlings under flood-drought abrupt alternation

Abstract Background Styrax tonkinensis (Pierre) Craib ex Hartwich faces challenges in expanding in the south provinces of Yangtze River region due to climate extremes like flood-drought abrupt alternation (FDAA) caused by global warming.Low tolerance to waterlogging and drought restricts its growth in this area.To study its antioxidant system and m

Recommendations for the use of microsatellite markers for parental reconstruction in rural sheep and goat populations

Proper knowledge about individual origin and pedigree is a major point for animal breeding and genetic livestock improvement.Mainly for goat, but also for sheep, breeding in Sicily information on these points is limited, and sometimes even misleading.Sheep and goat milk production is, in many regions and especially on Sicily, a rural enterprise, wh
