Development and application of optical fibre strain and pressure sensors for in-flight measurements

Fibre optic based sensors are becoming increasingly viable as replacements for traditional flight test sensors. Here we present laboratory, wind tunnel and flight test results of fibre Bragg gratings (FBG) used to measure surface strain and an extrinsic fibre Fabry–Perot interferometric (EFFPI) sensor used to measure unsteady pressure. The calibrated full scale resolution and bandwidth of the FBG and EFFPI sensors were shown to be 0.29% at 2.5 kHz up to 600 με and 0.15% at up to 10 kHz respectively up to 400 Pa. The wind tunnel tests, completed on a 30% scale model, allowed the EFFPI sensor to be developed before incorporation with the FBG system into a Bulldog aerobatic light aircraft. The aircraft was modified and certified based on Certification Standards 23 (CS-23) and flight tested with steady and dynamic manoeuvres. Aerobatic dynamic manoeuvres were performed in flight including a spin over a g-range −1g to +4g and demonstrated both the FBG and the EFFPI instruments to have sufficient resolution to analyse the wing strain and fuselage unsteady pressure characteristics. The steady manoeuvres from the EFFPI sensor matched the wind tunnel data to within experimental error while comparisons of the flight test and wind tunnel EFFPI results with a Kulite pressure sensor showed significant discrepancies between the two sets of data, greater than experimental error. This issue is discussed further in the paper

Sampling and analytical methods of the National Status and Trends Program Mussel Watch Project: 1993-1996 Update

Polycyclic aromatic hydrocarbons, butyltins, polychlorinated biphenyls, DDT and metabolites, other chlorinated pesticides, trace and major elements, and a number of measures of contaminant effects are quantified in bivalves and sediments collected as part of the NOAA National Status and Trends (NS&T) Program. This document contains descriptions of some of the sampling and analytical protocols used by NS&T contract laboratories from 1993 through 1996. (PDF contains 257 pages

An investigation into the application of international environmental Greenroads Certification standards to road construction in New Zealand

Greenroads is a USA designed environmental certification system for quantifying sustainable best practices for roadway design and construction. The major objectives of my research were to evaluate the suitability of Greenroads certification for use in New Zealand and compare the potential impacts of Greenroads compliance with the environmental outcomes achieved under the current New Zealand legislation and standards. A further two environmental certification systems, CEEQUAL (Civil Engineering Environmental Quality Assessment and Awards Scheme based in the UK) and INVEST (VicRoads – Integrated VicRoads Environmental Sustainability Tool managed by VicRoads in Australia) were also evaluated. For the Greenroads certification process to operate in New Zealand it was first necessary to undertake several Pilot Projects so that Greenroads criteria could be adapted to New Zealand conditions. Greenroads offered NZTA the option of undertaking an “A-Lined (pilot) Assessment” for the Te Rapa Bypass Road construction project that was underway in the Waikato region in 2011/12. Information regarding the design and construction of the Te Rapa Bypass was collated and submitted to Greenroads for the A-Lined Assessment. The results of the Greenroads A-Lined Assessment showed that the Te Rapa Bypass, with limited additional work, could have achieved a Greenroads Bronze Certificate. The collated information was also used as a basis to evaluate the CEEQUAL and INVEST systems. It was estimated that the Te Rapa Bypass could have achieved a CEEQUAL “Pass Award” or an INVEST two star rating. However to get any rating from CEEQUAL or INVEST a considerable amount of work would be required on all documentation. Greenroads, INVEST and CEEQUAL assessments show that currently, under the requirements of the New Zealand Resource Management Act (1991) (RMA) and other New Zealand legislation, New Zealand roads are already designed and constructed to a high environmental standard. Of the Greenroads, INVEST and CEEQUAL, certification systems, I consider that Greenroads is the better system for road projects in New Zealand. I recommend that New Zealand should use the Greenroads accreditation system to demonstrate that we meet international environmental standards in road construction. Much of the reporting required for Greenroads accreditation can be developed with, and incorporated into, the RMA consent process

Kansas: Baseline Report - State Level Field Network Study of the Implementation of the Affordable Care Act

This report is part of a series of 21 state and regional studies examining the rollout of the ACA. The national network ---- with 36 states and 61 researchers ---- is led by the Rockefeller Institute of Government, the public policy research arm of the State University of New York, the Brookings Institution, and the Fels Institute of Government at the University of Pennsylvania.The Kansas report highlights the diverse approaches to implementation taken by elected officials including Insurance Commissioner Sandy Praeger, Governor Sam Brownback, and the Kansas Legislature. The political landscape changed this year when Commissioner Praeger decided not to seek re-election. Her replacement, Commissioner-Elect Ken Selzer, has expressed opposition to the ACA

Between Worlds: Securing Mixed JavaScript/ActionScript Multi-Party Web Content

Mixed Flash and JavaScript content has become increasingly prevalent; its purveyance of dynamic features unique to each platform has popularized it for myriad Web development projects. Although Flash and JavaScript security has been examined extensively, the security of untrusted content that combines both has received considerably less attention. This article considers this fusion in detail, outlining several practical scenarios that threaten the security of Web applications. The severity of these attacks warrants the development of new techniques that address the security of Flash-JavaScript content considered as a whole, in contrast to prior solutions that have examined Flash or JavaScript security individually. Toward this end, the article presents FlashJaX, a cross-platform solution that enforces fine-grained, history-based policies that span both Flash and JavaScript. Using in-lined reference monitoring, FlashJaX safely embeds untrusted JavaScript and Flash content in Web pages without modifying browser clients or using special plug-ins. The architecture of FlashJaX, its design and implementation, and a detailed security analysis are exposited. Experiments with advertisements from popular ad networks demonstrate that FlashJaX is transparent to policy-compliant advertisement content, yet blocks many common attack vectors that exploit the fusion of these Web platforms
