This paper presents, an Electro-Mechanical Actuator (EMA) based position control system with redundancy technique is being presented. The servo system is composed of two chains, a prime chain and a redundant chain, which includes the position servo system of the EMA. Only one chain works at a time, probably the main chain operates during normal condition of the system. A new, simpler fault detection...

Abstract Rectal duplications are rare anomalies. Recently, we observed four cases of rectal duplication, each presenting with different clinical features including chronic constipation, a prolapsing rectal polyp, a growth from the vulva, and acute retention of urine. The variety of clinical presentations may lead to delay in diagnosis and multiple operations.
