In recent years, the finite-time and fixed-time control techniques have drawn much attention. This letter will present a new method for designing predefined-time adaptive sliding mode controller with prescribed convergent region. More specifically, class $\mathcal{K}^{1}$ function is used to con...
Aiming at the singular problem of large nonlinear error caused by extreme change rotation in five axis NC machining complex surface. An optimization algorithm tool path region is proposed. Taking a-c double turntable linkage machine as an example, firstly, mathematical models local milling ability, bandwidth and inclination are established. Based on two constraint models, mechanism singularity ...
Introduction: Causes of head and neck cancers (HNCs) are multifactorial, and few studies have investigated the association between chemical exposure and HNCs. The objective of this study was to investigate associations between HNCs, agricultural occupations, and pesticide exposure. The potential for the accumulation of pesticides in the adipose tissue of patients was also investigated. Materi...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
fuzzy logic has been developed over the past three decades into a widely applied techinque in classification and control engineering. today fuzzy logic control is one of the most important applications of fuzzy set theory and specially fuzzy logic. there are two general approachs for using of fuzzy control, software and hardware. integrated circuits as a solution for hardware realization are us...
