Due to the foveal organization of our visual system we have to constantly move our eyes to gain precise information about our environment. Doing so massively alters the retinal input. This is problematic for the perception of moving objects, because physical motion and retinal motion become decoupled and the brain has to discount the eye movements to recover the speed of moving objects. Two dif...

Smooth pursuit eye movements allow the approximate stabilization of a moving visual target on the retina. To study the dynamics of smooth pursuit, we measured eye velocity during the visual tracking of a Gabor target moving at a constant velocity plus a noisy perturbation term. The optimal linear filter linking fluctuations in target velocity to evoked fluctuations in eye velocity was computed....

A computer controlled HMMWV automatically retraces a previously recorded path using navigation data, a process we have termed retrotraverse. A Kalman filter combines the output of two navigation systems, an inertial dead reckoning system and a differential GPS, both with and without carrier phase detection. During retrotraverse, the mobility controller uses a velocity controller and pure pursui...

Sparse coding in a redundant basis is of considerable interest in many areas of signal processing. The problem generally involves solving an under-determined system of equations under a sparsity constraint. Except for the exhaustive combinatorial approach, there is no known method to find the exact solution for general dictionaries. Among the various algorithms that find approximate solutions, ...

In this paper we consider the problem of air to ground missile guidance system using fuzzy controller which uses Proportional Navigation and Pure Pursuit methods. The fuzzy controller’s rules are defined using Tabu Search (TS). The missile model is assumed as three degree of freedom (3DOF) (assuming the analysis in the vertical plane only). This paper presents numerical results for applying the...

In addition to pure software engineering educationor training-related topics, topics of interest include education and training in the mathematical, computer science, and engineering backgrounds required for the successful pursuit of software engineering. Papers may also relate to software engineering standards efforts, software engineering curriculum initiatives and similar themes as long as t...
