This paper studies the influence of road camber on the stability of single-track road vehicles. Road camber changes the magnitude and direction of the tire force and moment vectors relative to the wheels, as well as the combined-force limit one might obtain from the road tires. Camber-induced changes in the tire force and moment systems have knock-on(More)
This article presents a parametric approach to the optimal nonlinear control problem. This contribution is based on reducing the nonlinear optimal control problem to a sequence of linear time-varying ones and approaching the desired optimal control by a sequence of linear algebraic equations. This approach provides a solution which can be obtained in a(More)
In 2014, we assessed the effectiveness of Medical Taping Concept (MTC) in Primary Dysmenorrhoea (PD) with a single-blind, two-armed clinical trial (NCT02114723, with a follow-up of 4 menstrual cycles (pre-intervention: 2 months; post-intervention: 2 months) in a sample formed by 129 Spanish women aged 18-30 years with PD. We had two(More)
Burst oscillations can arise in racing motorcycles under a combination of high speeds, low roll angles and firm acceleration. This bursting occurs at weave-mode frequencies under conditions that cause the classical wobble and weave modes interact. Under race conditions this phenomenon can undermine rider confidence, and is consequently detrimental to lap(More)
Some of the more challenging aspects of modeling the mechanical dynamics of rotorcraft systems are addressed in this paper. The generic model here presented contains an articulated rigid-bladed rotor and fuselage. Special attention is given to the building of the main rotor model containing flap, lag and feather blade degrees of freedom for each of the(More)
— This paper addresses the control design for a nonlinear vessel manoeuvring model. The authors consider a highly nonlinear vessel 4 DOF model. The proposed control algorithm consists of a combination of an iteration technique that approximates the original nonlinear model by a sequence of linear time varying (LTV) equations whose solution converge to the(More)
