Flexibly-reconfigurable roll forming (FRRF) is a novel Case sheet metal forming technology by which sheet metal is shaped into a desired curvature using reconfigurable rollers and gaps.FRRF is conducive to producing multi-curvature surfaces by controlling the longitudinal strain distribution.However, it is difficult to predict the forming results s

The entrepreneurship intention research is mainly focused on individual related features, and the aspects of the external environment are not sufficiently considered.The present article aims to present and empirically test the Environment-Readiness Entrepreneurship Intention (EREI) Model, which consists of the perception of the environment (namely,

This paper describes the implementation of an improved clutter suppression method for the multiple pulse repetition time (PRT) technique based on simulated radar data.The suppression method is constructed using maximum likelihood methodology in time domain and is called parametric time domain method (PTDM).The procedure relies on the assumption tha

Background.Secondary hypertension is an uncommon cause of hypertension with extensive workup not recommended in most patients; however, further evaluation is generally recommended in young patients presenting with hypertension.Case Presentation.A 31-year-old female presented with history of elevated blood pressures.Secondary hypertension workup rev
