Life history parameters of the pea aphid, Acyrthosiphon pisum were studied at five constant temperatures on two cultivars of peas, Scout and Sancho. The development and mortality of juveniles and the life-span, age-specific fecundity and survivorship of adult aphids were recorded and used to construct life tables. The juvenile development period (from birth(More)
A direct approach to using finite element analysis (FEA) to predict organ motion typically requires accurate estimates of soft-tissue properties, which are very difficult to measure and are known to vary significantly between patients. In this paper, we describe a method that combines FEA with a statistical approach to overcome these problems. We show how a(More)
A method is described for generating a patient-specific, statistical motion model (SMM) of the prostate gland. Finite element analysis (FEA) is used to simulate the motion of the gland using an ultrasound-based 3D FE model over a range of plausible boundary conditions and soft-tissue properties. By applying principal component analysis to the displacements(More)
