The monotonous and frequent complication in the estimation of dielectric constant expressed interns of frequency in microwave range by incorporating Artificial Neural Networks (ANN). This computerized modus operandi is dependent on the deployment of a slotted line to take measurement which requires a numeric elucidation to resolve the dielectric constant. Automation of the dielectric constant is carried out by developing a computer program for gathering the data acquisition from the conventional setup and modernizing the same using ANN is described here. Investigational data gathered by this existing apparatus is used for training and testing the ANN trained with Back Propagation Algorithm (BPA). An equation formerly obtained from the literature, is used for estimating the dielectric constant. This is compared as an additional function with the computerized algorithm for calibration purpose. Thus, a novel ANN-based scheme for outlining the disparities between various dielectric materials to approximate the dielectric constant is experimentally analyzed using MATLAB.

In this work we propose a testing environment based on a personal computer, a data acquisition card and the LabVIEW<sup>TM</sup> software. The testing environment will be able to accept a test plan and convert it into test cases, provide means to test ANN-specific aspects in the implementation, run the designed tests and generate reports. Here we present our first results in the development of ... [Show full abstract] the test bench

Ground Truth Measurements For Quantifying Airborne Thermal Infrared Data

May 1987 · Proceedings of SPIE - The International Society for Optical Engineering

David L. Hawley

Quantifying airborne thermal infrared data has been a problem since the technology was created. A procedure is outlined to describe general ground truth measurements and their purpose. Specific ground truth procedures and equipment are detailed in a sample field deployment. The placement of instruments and equipment is discussed to make the user more aware of potential problems. Instruments ... [Show full abstract] utilized are radiometers, meteorological stations, and radiosondes. Equipment used includes reflectance/emittance targets, spatial resolution targets, and a water bath. A brief discussion of the reasons behind acquiring the ground truth data and how the measurements fit into the equations. This helps the ground truth personnel appreciate how small measurement errors can create major problems in the data analysis. The thermal infrared imager has to be characterized in order to quantify the data acquired in the field. A procedure for the characterization of the thermal infrared system response in the 8 micrometer to 13 micrometer band is outlined. The acquisition of data presenting the actual data flights is discussed. The sequence of ground truth data acquisition is presented. Particular attention is paid to acquiring time critical and non-time critical ground truth measurements. Sample data are presented to demonstrate the effect of ground truth measurements on thermal infrared data. The effect on quantifying relative temperature difference and absolute temperature differences is highlighted with respect to inadequate and less accurate data than desired.

Data Acquisition and Integration in the DGRC's Energy Data Collection Project

August 2001

The EDC project is developing new methods to make data that has been represented in disparate ways and stored in heterogeneous forms available to users in an integrated, manageable, and understandable way. Our approach is to represent the structure and types of data in the disparate collections in a standard format (called a domain model) and then to embed the domain model(s) into a large ... [Show full abstract] overarching taxonomy of terms (the ontology). Once thus standardized, the data collections can be found and retrieved via a single interface and access planning system. A major bottleneck, however, is the rapid inclusion of new data collections into this system. This paper describes some recent research in developing methods to automate the acquisition and inclusion processes. 1

An Integrated Approach to Ocean Observatory Data Acquisition/Management and Infrastructure Control U...

June 2004 · Marine Technology Society Journal

The proliferation of ocean observatories in the absence of agreed-upon standards for instrument and user interfaces and observatory control functions will constrain interoperability and cross-linking of disparate datasets. This will in turn limit the scientific impact of ocean observatories and increase their operating costs. Devising hardware-based standards will be difficult given the different ... [Show full abstract] internal architectures of existing and planned ocean observatories. This paper proposes that instrument, data, and observatory control processes be wrapped with standard web services which will provide a global software standard for these observatory functions. In addition to facilitating interoperability, state-full web services with workflow bindings for observatory instrument and data processes will enable dynamic user control of observatory configuration and the creation of multiple virtual instrument networks within one or more ocean observatories. These concepts are defined and illustrated through a number of use scenarios.
