During the development of the Soil Moisture Active-Passive (SMAP) High-Power Amplifier (HPA), a power glitch was observed with the characteristic of producing small 0.1-0.3 dB jumps in power across temperature. In order to troubleshoot this glitch behavior, a nonlinear model that...

Every LiDAR design faces the classic balancing act of signal versus noise. In order to maximize the range of a LiDAR, a receiver must amplify fractions of a micro-amp of photo current into a usable range for signal processing to occur, but...

The Flash LIDAR Emulator is a computer system designed to be functionally equivalent to a Flash LIDAR sensor camera. The system has the same hardware interfaces as the sensor, and produces images of comparable quality to the flash LIDAR sensor in real time (30 frames per second). The emulator is then used as a substitute for...

Carbon nanotubes (CNTs) are being studied for use in high-strength/lowweight composites and other applications. Recent research on thermal dissipation materials for high-power electronic devices is generating a lot of interest in various industries. Carbon nano tubes have attracted much attention due to their...

NASA’s Deep Space Network (DSN) is looking to modernize aging downlink receivers for telemetry, tracking, and radio science. It is looking to replace multiple types of custom-built, special-purpose receivers with a unified receiver architecture that...

Ceramic Column Grid Array (CCGA) packages have been increasing in use based on advantages such as high interconnect density, very good thermal and electrical performance, compatibility with standard surface-mount packaging assembly processes,...

Many methods have been developed for interrogation of wireless passive sensors. Surface acoustic wave (SAW) sensors and RF reflection sensors can receive and reflect electronic magnetic waves that are broadcast and received by the antennas....

The software package BALFIT was developed for both the processing of wind tunnel strain-gage balance data and the analysis of more general multivariate experimental data sets. The software uses automatically generated regression models for the analysis....

Support Vector Machines (SVM) can be used as a binary classifier for a wide range of data and problems. For text, it is often used to determine automatically if a document belongs to a given topic category. Automatic and reliable classification of documents can be an invaluable tool for industries that monitor...

This Python script will allow the user to read, analyze, and display National Oceanic and Atmospheric Administration (NOAA) Multi-Radar/Multi-Sensor(MRMS) mosaic tile files containing mosaic radar reflectivities on a national 3D grid. Simple diagnostics and plotting, as well as computation of composite...

The objective of this invention is to transform applications that process big data in arbitrary formats using the MapReduce parallel programming model and executed on the open-source Hadoop platform. Many legacy data-intensive applications do...

At the Hannover Messe trade fair in Germany, Eplan Software & Service, with its affiliate company Cideon, introduced Syngineer, an innovative communication and information platform that integrates mechanical engineering, software engineering, and controls engineering through one mechatronic structure. Eplan, a sister...
