We propose a novel high efficiency (≈40%) generator system capable of providing 1 kWe along with hot water on-demand. The integration of two novel concepts: 1) an internal combustion engine (ICE) operating on Spark-Assisted Compression Ignition (SACI) combustion of natural gas (NG), and 2) a bottoming Organic Rankine Cycle (ORC) with waste energy recovery (WER) from ICE exhaust enables the overa ...

TECHNICAL ABSTRACT: The NOAA Integrated Earth System Process and Predictions 2018 Subtopic 8.1.1 “Radio Occultation from Recoverable Air Balloons for Weather Applications” solicitation has the goal of demonstrating the feasibility of a hardware/software system for a balloon platform that has sufficient quality for measuring global navigation satellite system (GNSS) signals to enable retrieval ...

This proposal addresses subtopic 9.6.01, Low-cost Oceanic and Atmospheric Sensors and Observing Systems. It is proposed that two instruments for measuring atmospheric aerosols be commercialized to operate automatically and routinely. Both instruments have been used in research settings for many years and share several aspects of technology. They could both be commercialized with significant advant ...

The State Departments of Transportation (DOTs) have limited right-of-way (ROW) to construct stormwater treatment controls. Hence innovative self-contained portable stormwater treatment systems are needed to reduce impacts on streams, and other waters; recreation facilities, and habitat by addressing emerging stormwater pollutants, particularly the suspended and dissolved pollutants from highway co ...

A NOVEL TECHNIQUE IS PROPOSED USING A COMMERCIALLY AVAILABLE LOW-FLUX, ISOTOPIC SOURCE AND MULTIPLE DETECTORS FOR SPECTRAL TRANSMISSION/SCATTERING RADIATION DATA TO OBTAIN CHARACTERISTIC SIGNATURES OF EXPLOSIVE MATERIALS. THE AMOUNT AND ENERGY OF SCATTERING DEPENDS ON THE DENSITY, COMPOSITION AND SPATIAL DISTRIBUTION OF THE MATERIAL, WHILE NEUTRON TRANSMISSION DEPENDS ON THE ATTENUATION CAPABILITY ...

Halobutyl rubber is used as an inner liner for tubeless automotive tires because of its low permeability to gases and good compatibility with other tire materials. However, at high pressures and over prolonged time periods, tires leak. Factors such as under-inflation and heat are major contributors to tire damage. While the tires are slowly losing air pressure, consumers also do not maintain c ...

AN ICING DETECTION SYSTEM BASED ON OPTICAL REFRACTOMETRIC TECHNIQUES IS DECRIBED IN THE PROPOSAL. THE FIRST OMEGA GROUP, INC. PROPOSES TO DEMONSTRATE THE APPLICABILITY OF THIS CONCEPT TO ENABLE THE CONSTRUCTION OF INSTRUMENTATION THAT AUTOMATICALLY DETERMINES THE ONSET, DURATION, ACCU MULATION AND DISSOLUTION OF ICING ON AIRPORT RUNWAYS, PARKEDAIRCRAFT, AIRPORT NAVIGATIONAL AID STRUCTURES, ETC. TH ...

Machine learning and unsupervised classification have been applied to seafloor classification and benthic mapping using multibeam echosounders (MBES), Light Ranging and Detection (LiDAR), airborne hyperspectral, underwater optical cameras, and satellite imagery. Regardless of the sensor, data dimensionality reduction is an integral processing step of seabed mapping workflows . The most commonly im ...
