during last ten years i have been one the guest speakers who presented the principles of foot and ankle radiology in details since 2006 - 2015 in iranian congress radiology. in this presentation i am focusing on one the specific problems of the foot which is very common practice in the field of radiology and orthopaedic surgery. chronic foot pain has a broad spectrum of potential causes and ima...

Research has shown that training multi-layer perceptron networks to solve ordinary and partial differential equations (DEs) can be accelerated by reusing network weights from a previously solved similar problem. This paper compares weight reuse for two existing methods of defining the network error function. Weight reuse is shown to accelerate training of one ordinary and two partial DEs even f...

In this paper, a new method for interval solution of the n order linear ordinary differential equations (ODEs) with interval initial conditions is constructed. In this approach, by using the Neher’s algorithm [16], first we obtain a guaranteed enclosure solution for an initial point value problem and then based on the Moore’s idea [7, 13], we transform this solution to arrive at an interval sol...
