This paper focuses on the trajectory tracking problem of wheeled mobile robots not satisfying the ideal " rolling without slipping " constraints. Robust control laws are proposed to deal with the slipping of the wheels. The design procedure consists of three main steps. A bounded transverse function is firstly constructed, by which a smooth embedded(More)
α-solanine, a steroidal glycoalkaloid in potato, was found to have proliferation-inhibiting and apoptosis-promoting effect on multiple cancer cells, such as clone, liver, melanoma cancer cells. However, the antitumor efficacy of α-solanine on pancreatic cancer has not been fully evaluated. In this study, we inquired into the anti-carcinogenic effect of(More)
BACKGROUND To summarize the diagnostic and therapeutic experiences on the patients who suffered abdominal complications after cardiovascular surgery with cardiopulmonary bypass(CPB). METHODS A total of 2349 consecutive patients submitted to cardiovascular surgery with CPB in our hospital from Jan 2004 to Dec 2010 were involved. The clinical data of any(More)
A solution is presented to the robust control problem of wheeled mobile robots moving on an uneven surface that is not exactly known. Quadratic surface with unknown but bounded coefficients is utilized to locally approximate the uneven surface. The design procedure is based on the transverse function method, integrator backstepping, and Lyapunov redesign(More)
