The Acoustech Corporation as the prime contractor and the Pennsylvania State University - Applied Research Labc-atory as the subcontractor propose to design, manufacture, and test an underwater acoustic intensity probe containing a geophone and two-hydrophones encased in a neutrally buoyant package. The results of this proposed effort are anticipated to be highly successful since the researc ...

We propose a radically innovative approach to the problem of multiple access communication which promises to revolutionize the modern communication industry by dramatically increasing network throughput. Our approach is based upon two major novel components: (i) hybrid time-frequency allication of communication channel resources, and(ii) non-orthogonal, i.e., overlaping, multiplexed signals. Toge ...

The proposed research project is directed at the problem of reducing communications requirements for Situation Awareness Target location by using an optimal Kalman filter to predict target motion, and only communicating data when the target position differs sufficiently from the position predicted by the filter. Our Phase I approach is to quantify the bandwidth limitations of the communications s ...

Every new engineering design task involves several stages, including conceptualization, synthesis, evaluation, embodiment, and detailed design followed by prototyping and redesign. Recognizing that new design ideas often arise by reusing and adapting prior design ideas through direct recall and analogy, we will undertake research aimed at developing representation and indexing schemes for large c ...

Currently, advanced tools for modeling injection modeling of thermoplastics and predicting formed part dimensional stability and residual stress content use the static bulk modulus of the polymer at the temperatures and pressures associated with the molding process. The short cycle times associated with injection molding, however, could be more accurately modeled if dynamic bulk modulus data were ...
