My current research is primarily in the mathematics of voting. This discipline lies at the interface of mathematics, political science, and economics, though it has connections to any field which could involve aggregation of preferences, such as statistics or psychology. It also is a proven, fertile field for undergraduate research. The math of voting, in its classical form, asks questions abou...

than a third of a representative sample of U.S. engineering educators considered the study of differential equations to be necessary for an engineer’s education. When the Society for the Promotion of Engineering Education surveyed over 500 teachers of engineering during the 1920s, it found that only 29% of the instructors believed that differential equations were of primary importance in the st...

Every stable controllable input pair (Ã , B̃ ) is equivalent to an input pair which is in Hessenberg form and is input normal (AA∗ + BB∗ = I ). (A,B) is represented as a submatrix of the minimal number of Givens rotations. The representation is shown to be generically identifiable. This canonical form allows for fast state vector updates and improved conditioning of system identification problem...

Virtual creatures operating in a physically realistic 3D environment, as originally introduced by Karl Sims, provide a challenging domain for artificial evolution. However, few coevolutionary experiments have been reported. Here we describe the results of our experiments on the evolution of physical combat among virtual creatures: essentially, we evolve creatures that trade blows with each othe...

The present paper constitutes an investigation on two twin classes of matrices, which result as Hadamard products of already known classes of matrices. The classes under consideration have Brownian form, which is defined by 3n − 1 parameters. Their inverses are matrices of lower Hessenberg form, the elements of which can be expressed analytically by these parameters. The explicit forms of the i...
