Partial Differential Equations on the Intel Touchstone Delta Supercomputer (2008)

Nikzad Toomarian, Amir Fijany, Jacob Barhen, Nikzad Toomarian, Amir Fijany, Jacob Barhen

Evolutionary partial differential actuations are usually solved by discretization in time and space, and by applying a marching in time procedure to data and algorithms potentially parallelized in...

Preventing Computational Chaos in Asynchronous Neural Networks (2008)

Jacob Barhen, Vladimir Protopopescu

Abstract. One of the primary advantages of artificial neural networks is their inherent ability to perform massively parallel, nonlinear signal processing. However, the asynchronous dynamics...

Massively Parallel Algorithms for Solution of Schrodinger Equation (2004)

Fijany, Amir, Barhen, Jacob, Toomerian, Nikzad

In this paper massively parallel algorithms for solution of Schrodinger equation are developed. Our results clearly indicate that the Crank-Nicolson method, in addition to its excellent numerical...

(abstract) Application of Neural Networks to Hyperspectral Unmixing (2004)

Barhen, Jacob, Toomarian, Nikzad

The emergence, in recent years, of hyperspectral sensors provides a tremendous opportunity for advancing the process of detailed and direct remote detection and identification from space of targets...

Time Parallel Solution of Linear Partial Differential Equaitons on the Intel Touchstone Delta Supercomputer (2004)

Toomarian, Nikzad, Fijany, Amir, Barhen, Jacob

This paper presents the implementation of a new class of massively parallel algorithms for solving certain time-dependent partial differential equations (PDEs) on massively parallel-supercomputers.

Three-dimensional route planning for large grids (2004)

Brener, Nathan E, Iyengar, Sitharama S, Looney, Hua C, Vakamudi, Narayanadas, Yu, Decai, Huang, Qianyu, ...

We have developed a 3D route planner, called 3DPLAN, which employs the A* algorithm to find optimum paths. The A* algorithm has a major advantage compared to other search methods because it is...

On Computing Mobile Agent Routes for Data Fusion in Distributed Sensor Networks (2004)

Qishi Wu, Jacob Barhen, S. Sitharama Iyengar, Vijay K. Vaishnavi, Hairong Qi, ...

The problem of computing a route for a mobile agent that incrementally fuses the data as it visits the nodes in a distributed sensor network is considered. The order of nodes visited along the route...

Site-Specific Attachment of gold Nanoparticles to DNA Templates (2001)

Stevenson, Karen A., Muralidharan, Govindarajan, Maya, Leon, Wells, Jack C., Barhen, Jacob

DNA was used as a scaffold for the binding of gold nanoparticles using a standard chemical technique. A DNA template was designed with amino-modified thymines located every 3.7 nm which would allow...

A massively parallel computation strategy for fdtd: time and space parallelism applied to electromagnetic problems (1995)

Amir Fijany, Michael A. Jensent, Yahya Rahmat-samiit, Jacob Barhen

In this paper, we present a novel strategy for incorporating massive parallelism into the solution of Maxwell’s equations using finite-difference time-domain methods. In a departure from previous...

Reduction in the reconstruction error of computer-generated holograms by photorefractive volume holography (1993)

Rosen, Joseph, Segev, Mordechai, Yariv, Amnon, Barhen, Jacob

We suggest a method for coding high-resolution computer-generated volume holograms. It involves splitting the computer-generated hologram into multiple holograms, their individual recording as volume...
