Although large asteroids and comets have impacted the Earth in the past, we do not want large ones to impact us in the future. Can we prevent this from happening? A considerable amount of work continues to be done in detecting asteroids that may pass

It is thought that many asteroids in orbits close to the Earth have been moved from outer orbits by the Yarkovsky effect. The orbital change is caused by solar heat absorption and surface re-radiation, creating a recoil force on the asteroid that eit

There is growing interest in the applications of wavelets as basis functions in solutions of integral equations, especially in the area of electromagnetic field problems. In this article we apply a wavelet expansion to the solution of the three-dimen

We have implemented a three-dimensional point reconstruction method based on stereo radiography techniques utilizing a real-time radiography (RTR) laboratory. The continuous radiographic image coupled with computerized position control and feature po

Our preliminary design of a lunar far-side correlation array is based on a two-dimensional nonuniformly spaced array of elemental dipoles extending to a maximum diameter of 1000 km. Phase 1 consists of deploying antennas over a 17 km diameter in the

It has been found that a close relationship exists between the spectral reflectance and the health as well as the productivity of soybean canopies. Basing on this property, a remote sensing method was used to assess the plant productivity and health,
