GreensulateTM is an affordable, biodegradable replacement for polystyrene/polyurethane foam building products, poised to replace petrol-foams in the rigid board insulation market.  This patent pending technology uses the vegetative growth stage of a benign fungus (mycelium: P.ostreatus, I.obliquus, F.formentarius A.arvensis) to bond loose particles into a cohesive whole.  The fungus operate ...

The design, construction, and feasibility testing of X-ray fluorescence (XRF) based instrumentation capable of detecting the presence of atomic species within ambient particulate matter (PM) on a near real-time basis has been completed successfully. The XRF analysis is made feasible for hourly ambient PM samples through the implementation of novel high-volume flow impaction and post-im ...

Air particulates have been identified as a source of primary and secondary health risks. Even small, short-term increases in the amount of air particulate contamination in the atmosphere can produce significant increases in both mortality and morbidity from respiratory and cardiovascular diseases. For example, recent studies show that just two hours of breathing fine particles in a city from sou ...

We propose to demonstrate the ability to non-evasively probe the characteristics of material properties using acoustical waves through thermal conversion of a remote laser pulse. The advantages of proposed system as an inspection and identification technique are: 1) Non-contact: Sensor does not require contact with container 2) Stand-off: Sensor could be located many meters away from container 3 ...

ADVANCED STRUCTURAL MATERIALS USED IN THE FABRICATION OF SUBMARINES CAN SUSTAIN LARGE STRAINS DURING THE FORMATION PROCESS CAUSED BY EXPLOSIVE LOADINGS. THE COMPUTATIONAL SOLID MECHANICS COMMUNITY HAS RECENTRLY RECOGNIZED SERIOUS SHORTCOMINGS IN CALCULATIONS USING MATERIAL MODELS IN THIS LARGE STRAIN REGION. BECAUSE OF THE IMPORTANCE OF CALCULATIONS IN UNDERSTANDING THE SHOCK RESPONSE OF SUBMARINE ...

We propose a stochastic-finite-element based methodology to address these requirements: (i) Characterize material variability; (ii) Quantify corresponding ground-shock variability; and (iii) Design instrumentation plan. The site is discretized into N finite-elements; rock properties over this domain are characterized as the components of an N-vector stochastic field. The probabilistic characterist ...

Weidlinger Associates Inc. proposes to develop effective technology for simulating explosive detonations within civil buildings where the propagation of airblast and failure of weak internal walls are strongly coupled. We will conduct a field test program designed to complement other internal detonation testing efforts such as DTRA''s Distinct Cobra, expanding the available database. We will perfo ...

An approach for performing high fidelity modeling for blast and progressive collapse simulations of buildings will be developed. The modeling approach will allow complete simulations of building response to be performed within several days of computing time on desktop PCs. An 'easy to use' modeling interface will also be demonstrated in this effort. All response regimes will be addressed includi ...
