The focus is on different flight scenarios within a safe flight envelope for a mathematical model of an airliner, aimed at being able to contribute to the assessment of aircraft control law designs. The implications of the study can be applied to other similar dynamical systems. In a multi-dimensional nonlinear system, computation of an exact ROA is difficult, as is its graphical representation and interpretation. Problems become more complicated when the behavior of system parameters (such as aircraft control surfaces) is also taken into account. The system under consideration here is a polynomial representation of the NASA GTM aircraft model. Bifurcation analysis was carried out on this nonlinear aircraft model for understanding its steady state behavior with respect to input parameters and evaluating the multiple solution branches to give an indication as to the steady-state ROA for varying input parameters. Time history-based ROA analysis was then carried out, to understand the transient state response and for determining a multidimensional ROA for a constant input parameter value. This helped in specifying the maximum value of disturbance an aircraft can be subjected to and still return to the stable trim point. Differences between the bifurcation analysis and the time history results highlight the difficulty in estimating a ROA for a multi-attractor multi-parameter multi-state nonlinear aircraft system. The benefits of combining the results obtained from bifurcation analysis with time history-based region of attraction analysis is discussed; this offers the prospect of a ROA within which, for a range of predefined input parameters, an aircraft subjected to any disturbance will return back to a specific stable trim point. The solution hence provides a measure of robustness for aircraft systems and aircraft control law designs.","PeriodicalId":344030,"journal":{"name":"2019 6th International Conference on Signal Processing and Integrated Networks (SPIN)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114386921","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 reflected GPS signals may contain information on soil moisture, ocean waves, and altitude [1]–[4]. Space radar systems have also been a topic of intense interest for several decades, as a means of providing global coverage for both military and geoscience applications [5]–[7]. These systems implement Synthetic Aperture Radar (SAR), Ground Moving Target Indicator (GMTI), and Space Time Adaptive Processing (STAP) algorithms to detect targets and form images. Orbit selection is important for these systems to provide optimum coverage and performance. By using reflected GPS signals to implement space-based bistatic radar, a more robust and cost-effective system could be fielded. However, the performance analysis of such a system would be complex, since the orbits of the receiving spacecraft and the GPS constellation will be significantly different, and their interactions dynamic. This relationship between the receiving satellite's orbit and the GPS constellation was the subject of the research. A prototype antenna array was used to estimate the resolution and signal levels of the system for various transmitter/receiver relationships. Based on an understanding of the desired signal characteristics for bistatic GPS, a family of orbits was simulated to determine the dependency on inclinations and altitudes.","PeriodicalId":344030,"journal":{"name":"2019 6th International Conference on Signal Processing and Integrated Networks (SPIN)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124694685","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}

Bitcoin revolutionized this conventional view of a cryptocurrency, trading decentralized, distributed ledger, completely secured by the majority rule without predetermined authority or owner. Only standard cryptographic primitives such as signatures and hash functions were used to achieve security. Though other cryptocurrencies such as Bit-gold and B-money which are among the authority-free cryptocurrencies, Bitcoin is the first one to experience public acceptance on a large scale. There are various factors which contribute to Bitcoins success, though there is still a little question of doubt that the decentralized design of blockchain technology and perceived resilience to government or third-party intervention played an extremely crucial role in its uptake. Distributed crypto cash, more specifically in Blockchain technology has hailed as one key and most eminent and widely accepted innovation of Bitcoin.

It is designed over flexible polycarbonate substrate having radiating copper metallic patch. The decreasing amplitude corrugations which are designed in exponential manner are stripped off at front and back side of the antenna. The antenna exhibits good front to back ratio and peak realized gain. The peak realized gain ranges from 5 dBi to 12.7 dBi for $250 boldsymbol{mu} mathbf{m}$ thickness and it ranges from 2.18 dBi to 11.73 dBi for $500 boldsymbol{mu} mathbf{m}$ thickness. The antenna exhibits good radiation characteristics over the designed frequency range in terms of peak realized gain, front to back ratio as well as 3D radiation plots with that being better for $250 boldsymbol{mu} mathbf{m}$ antenna as compared to $500 boldsymbol{mu} mathbf{m}$ antenna. The antenna with $250 boldsymbol{mu} mathbf{m}$ thickness gives unidirectional radiation pattern almost covering the entire designed frequency range.

The International GNSS Service (IGS) distributes post-processed GPS satellite orbits that give the satellite positions at 15 minutes interval. For GPS applications involving high-rate (1 Hz) GPS, it is necessary to know the satellite positions at one second intervals. One approach of doing this is to interpolate the IGS precise orbit using a polynomial or trigonometric function. An alternative approach is to use the precise ephemeris distributed by the IGS to obtain the satellite position and velocity at the initial epoch and then perform numerical integration to determine the satellite position at one second intervals. JPL's GPS Inferred Positioning System/Orbit Analysis and Simulation Software (GIPSY/OASIS) is used to numerically integrate the orbit of a single GPS satellite in order to determine the position at one second intervals. A comparison of the numerically integrated positions and the interpolated positions shows that the numerically integrated satellite positions more closely match the IGS orbits than an orbit constructed using a trigonometric interpolation.","PeriodicalId":344030,"journal":{"name":"2019 6th International Conference on Signal Processing and Integrated Networks (SPIN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130613498","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}
