In this paper, a robust autopilot is proposed using stable interpolation based on Youla parameterization. The most important condition of stable interpolation between local controllers is the preservation of stability so that each local controller can ensure stability for an open neighborhood around a nominal point. The proposed design used fixed-order robust controller with parameter-dependent...

OBJECTIVES To investigate the knowledge and appropriateness of practices relating to RPD clasps of dentists working in NWFP. STUDY DESIGN & SETTING A questionnaire-based-survey conducted at the Department of Prosthodontics, Khyber College of Dentistry Peshawar. SUBJECTS & METHODS Participant's qualifications, experience in dental practice and the proportions of practice time they devoted to...

AIM Special care is required in the fabrication of a Class IV Aramany removable partial denture (RPD) in order to minimize the stress distribution to supporting tissues. Using the finite element method, the aim of this study was to analyze the distribution stress to supporting tissues when a Class IV Aramany RPD is worn. METHODS AND MATERIALS Three RPD designs with circumferential cast retain...

This paper deals with the modeling, analysis, design and simulation of a robust control method for a permanent magnet synchronous machine (PMSM) supplied with a PWM inverter based on a LPV (Linear Parameter Variation)  standard controller. Under the influence of uncertainties and external disturbances, by a variation of ±150% of motor parameters from the nominal values, the robust performance c...

BACKGROUND Renal pelvis dilatation (RPD) occurs in 1% of fetuses. Severe RPD (>15 mm) is frequently associated with urinary tract pathology. For the majority with mild (5 to 9 mm) to moderate (10 to 15 mm) RPD, however, there is uncertainty about the risk of abnormalities and how much postnatal investigation is required. STUDY DESIGN Systematic review of cohort studies of fetuses with RPD < o...
