The micro milling operation is one of the manufacturing processes, which can produce 3D parts in the range of less than a millimetre.Miniaturization of components results in increasing the ratio of surface area to volume of components, which in turn increases the role of surface on Mood the component performance.Therefore, anticipating the relation
This paper describes a nonlinear deterministic controller design for a helicopter with an underslung external load system.A robust control Serving Board approach is considered for the control law development.The system is considered as a cascade connection of an uncertain nonlinear system.The controller is designed to ensure the stabilization of th
Objective:The aim of this study was to evaluate the factors that led to re-revision surgeries in patients who underwent revision total hip arthroplasties (THA).Methods:A total of 352 revision THAs in 274 hips of 252 patients (January 2001-December 2012) were retrospectively analyzed.Patients with a history of strict a major component revision surge
