Specifically, circularly polarized (CP) antennas find special interest in satellite communications and applications involving mobile transceivers. For mm-Wave and THz band, gain characterization for CP antennas is a difficult task due to phase errors in alignment. To avoid practical difficulties in traditional CP gain measurement method, we propose a simple, phase-less measurement method. The method relies only on amplitude based measurements, utilizing scattering from readily available structures. In this work, we develop the theory and demonstrate the measurement results for a radial line slot array antenna (RLSA) operating at 106 GHz.","PeriodicalId":318539,"journal":{"name":"NAECON 2014 - IEEE National Aerospace and Electronics Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127761918","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}

We outline QuEST elements and tenets towards a reasoning approach that achieves human intelligence amplification (IA) as opposed to data aggregation from machine artificial intelligence (AI). In a use case example for automatic target exploitation, we showcase the need for enhanced understanding of the man (mind-body cognition) and the machine (sensor-based reasoning) for establishing a cohesive narrative of situational activities.","PeriodicalId":318539,"journal":{"name":"NAECON 2014 - IEEE National Aerospace and Electronics Conference","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121618699","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 two piers are inline and have a tunable gap between them, with gap distance varying between 60-200 nm. The proximal ends of the piers are contiguous with a Co-Planar Waveguide structure that allows for testing. The basic pier structure was created by ablation of a customized MMA/PMMA stack using a JEOL laser system. A layer of Ti-Au was then deposited on silicon using standard electron beam deposition techniques. Electromagnetic testing of the structures was correlated with SEM imagery for characterization of electrical properties and gap integrity. The overall design is to create a biological sensing bridge by tethering molecules across the distal ends of the piers thereby completing the circuit. The type and composition of biological bridge provides sensor selectivity and sensitivity.","PeriodicalId":318539,"journal":{"name":"NAECON 2014 - IEEE National Aerospace and Electronics Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114444693","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}

Human-centric sensing has already been successfully implemented as integrated network architecture component in many operational intelligent systems in various industry areas such as defense, healthcare, energy or disaster management. The process of integration of Human-centric sensing into the system can be lengthy and complicated because of disparate data formats, modality and connectivity interfaces. Extending an existing system by new, and possibly future, sensors may result in low-level integration issues. There is a need for a generic architecture that will be able to dynamically accommodate new sensors and to provide fusion of all sensed data. In this paper, we extend our previous work of developing an architecture that supports seamless integration and development of platforms to enhance situational awareness in the context of Human-centric sensing.","PeriodicalId":318539,"journal":{"name":"NAECON 2014 - IEEE National Aerospace and Electronics Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122768492","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}

A methodology for detecting hardware Trojans (HTs) that has been pursued recently is based on comparing the power and delay response of a genuine chip to the manufactured chip/device under test (DUT). However, the probability of detecting the HT remains small in many cases due to the low probability of activating the concealed circuits. This paper proposes a technique to increase HT activity during testing by inserting probability increase circuits (PICs) at critical points in the design. Preliminary results for a standard HT example show a reduction in time for HT activation of over 95% with modest increases in power, size, and delay overhead.","PeriodicalId":318539,"journal":{"name":"NAECON 2014 - IEEE National Aerospace and Electronics Conference","volume":"288 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130019643","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}
