These amplifiers will receive gas sensing information from four different nanoparticle assemblies using monolayer Graphene sheets. The cross talk was minimized by using guard rings surrounding the amplifiers. Guard rings serve as dummy collectors for the minority carriers crossing the parasitic BJT devices within the quad instrumentation amplifier System on chip (SOC). This study aims determination of the gas sensing signature array (GSSA), including the type of gas, its concentration, and dynamic performance (rise and fall times). The developed devices were based on the detection of the change in the graphene electrical characteristics when exposed to various gases. The paper presents the first phase of a long-term project, detailing hardware and circuit simulation software design, and its practical implementation, leading to the optimum gas sensing system resulting from the GSSA data. The practical model was based on monolayer graphene films deposited using CVD process on top of SiO2 layers of silicon substrate wafers. Gold electrodes were deposited with sputtering process. The device was then tested with CO2 gas with 100% and 5% concentrations to estimate its sensitivity. As high as 48% change in resistance was detected from 100% CO2 concentration, and near 4% change in response to 5% CO2 concentration, a level of change that can be easily monitored by the quad CMOS instrumentation chip. A gain of 83dB for the instrumentation amplifier was calculated from the circuit simulation. The Quad instrumentation amplifiers were developed using MOSIS service and showed as low attenuation as 90dB.","PeriodicalId":133804,"journal":{"name":"2015 National Aerospace and Electronics Conference (NAECON)","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116144625","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 this paper, we discuss the motivating factors for development of performance prediction (2P) for radar. In the case of adaptive radar, the optimal unconstrained transmit waveform (for detection) is easily computed. However, it is generally not suitable for practical use. Therefore, we apply constraints on the waveform design and are forced to sacrifice signal-to-interference-and-noise ratio (SINR) to meet the constraints, i.e., there is no free lunch. Understanding the consequences of applying constraints in arbitrary waveform design can benefit the decision making process of an adaptive system by providing insight into selection of the transmit signal. We develop a use-case for 2P and give examples of successful 2P models. We discuss the trade-space between optimality and speed in the waveform design process. Lastly, we mention several current areas of promising research, selected results and comment on future needs to realize effective 2P for radar.","PeriodicalId":133804,"journal":{"name":"2015 National Aerospace and Electronics Conference (NAECON)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126703450","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}

However, one cannot overlook the fact that these sensors are quite low-cost, can be easily mounted on small robotic systems and are computationally very efficient. In this paper, we try to use an infrared sensor array network to detect a person in its environment and also track the person. A traditional particle filter algorithm using a given motion model poses challenges for tracking a person using infrared sensors, primarily because the motion model might fail to keep up with complex dynamic changes in motion directions coupled with the fact that in the presence of noisy readings or missed detections from the infrared sensor data, small errors in position estimation could add up over time making the particle filter completely lose track of the person. In this paper, instead of using a fixed motion model, we propose to learn a motion model statistically from the initial target motion data and subsequently use this model with the particle filtering approach in order to track the person. In addition, the learnt motion model is regularly updated so as to support the particle filtering approach in establishing a more accurate track of the person.","PeriodicalId":133804,"journal":{"name":"2015 National Aerospace and Electronics Conference (NAECON)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128892084","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}

However, to be economical for global production and utilization, the efficiency of solar cells must increase without escalating manufacturing costs. Because of the abundance of silicon and vast knowledge obtained from silicon study, exhaustive exploitation of silicon-based solar cell design is vital to meet both criteria. Positive thermal control and improved photon recycling are two methods to increase solar cell efficiency. A recently developed hybrid multi-junction silicon (HMJ-Si) solar cell architecture was designed to positively manage these two factors, as well as the common resulting photonic interference pattern generated from the electrical contact gratings. Because of the integrated air gap between two stacked silicon substrates, this sandwiched-cavity imparted a 1.70C differential temperature. The top and bottom substrates were electrically connected in parallel via a copper o-ring with a thickness of 385μm which was the optimal, calculated air gap distance for photon propagation wavelengths of 800nm-1100nm. The HMJ-Si solar cell was tested using a solar simulator with an air mass 1.5 full spectrum sunlight output and a class II pyranometer with a spectral response of 310nm-2800nm. The HMJ-Si solar cell demonstrated photovoltaic efficiency of 8-10%.","PeriodicalId":133804,"journal":{"name":"2015 National Aerospace and Electronics Conference (NAECON)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114960702","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}
