The Soft Computing approach allows advanced multi-parameter data processing in composite materials testing. The HPC parallel implementation overcomes the limits due to the great amount of data and the complexity of data processing. Our experimental results illustrate the effectiveness of the U-BRAIN parallel implementation as defect classifier in aerospace structures. The resulting system is implemented on a Linux-based cluster with multi-core architecture.","PeriodicalId":162403,"journal":{"name":"2014 IEEE Metrology for Aerospace (MetroAeroSpace)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122664566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The airfoil of interest for this study is a Clark Y airfoil with a 0.3048 m chord length set to a 0 degree angle of attack. Wind tunnel testing and 3D numerical simulations using ANSYS CFX were used to analyze Pitot static probe measurements for a probe extending forward of the airfoil chord line from 0 to 20 cm at Reynolds numbers from 1 × 105 to 5 × 105. The results obtained demonstrate how probe placement and Reynolds number affect the measured stagnation and static pressure which are used in determining velocity and altitude.","PeriodicalId":162403,"journal":{"name":"2014 IEEE Metrology for Aerospace (MetroAeroSpace)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126503911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These components are commonly based on alternating layer pairs of amorphous materials. Particularly, for cryogenic applications highly reflective silicon gratings can be a promising low-noise alternative to these layer stacks. In this contribution we present a method to evaluate thermal noise of such micro-structured surfaces. For the example of the Einstein Telescope low-frequency detector it is found that coating thermal noise can be reduced up to one order of magnitude by using monolithic silicon gratings instead of conventional multilayer mirrors.","PeriodicalId":162403,"journal":{"name":"2014 IEEE Metrology for Aerospace (MetroAeroSpace)","volume":"195 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121132147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The automatic signal classification is an important feature for the application of Cognitive Radio in aeronautical communications. Cognitive Radio will allow of automatically adapting the transmission parameters according with the radio environment and the channel conditions, with the aim of assuring reliable communication and high data rates. In particular, an algorithm has been proposed, allowing to identify signals transmitted according with the new proposals for aeronautical communication systems, and to distinguish such signals from linearly modulated ones and noise. The developed algorithm has been then validated on simulated signals, by considering a model of the aeronautical channel.","PeriodicalId":162403,"journal":{"name":"2014 IEEE Metrology for Aerospace (MetroAeroSpace)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132735507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, the paper focuses on Carbon Dioxide (CO2), which is the most important aviation greenhouse gas, and whose column density data can be used for environmental monitoring purposes and to support the development and validation of aircraft engines and Systems for Green Operations (SGO). The proposed measurement techniques are based on a near-infrared bistatic Light Detection and Ranging (LIDAR) system using a modified version of the Integrated Path Differential Absorption (IPDA) technique currently adopted in state-of-the-art (monostatic) remote sensing LIDARs. Target surfaces of known spectral reflectance and Bidirectional Reflectance Distribution Function (BRDF) are irradiated with two laser beams of appropriate wavelengths. The first wavelength is selected in coincidence with one vibrational band of the CO2 molecule, exhibiting significant absorption phenomena (absorption line). The second wavelength is selected in the same transmission window but outside the absorption line. By measuring the difference in incident energy between the two beams, and inverting the differential transmittance models, it is possible to determine the pollutant column density. Parasite effects include haze, precipitation and dust particulate, which can be modelled as well. In addition to the bistatic LIDAR technique, a monostatic control technique is also proposed in this paper for experimental and calibration purposes.","PeriodicalId":162403,"journal":{"name":"2014 IEEE Metrology for Aerospace (MetroAeroSpace)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130260765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such equipment has allowed AFIT to integrate new communication devices/systems while upgrading the W-3PL helicopter. Some selected tasks performed with this equipment engaged have been discussed. Also, problems arising while actuating and testing the developed software to integrate communication devices/systems (including digitally controlled radio stations of the RRC, HARRIS, and MR6000 types, communication control panels of the PSŁ-1 type and multifunction displays of the MW-1 type) have been given consideration in the scope of the software functionality and reliability.
