Then iterative k-means clustering is applied for clustering on lower dimension space with only 3 features. In addition, Unsupervised Extreme Learning Machine (UELM) is used for network intrusion detection in this implementation. We have experimented on KDD-99 dataset, the experimental results show around 91.86% and 92.12% detection accuracy using unsupervised deep learning technique AE and RBM with K-means respectively.

The main goals of these controllers are to eliminate the energy loss throughout the system components (mainly the lithium ion battery and the Ultra-capacitors), and to produce a perfect system response which deliver the exact power demand needed at the output.

In this work, a heuristic technique is used where the conductive topology of the metasurfaces for a fixed form factor is optimized by a multi-objective genetic algorithm mimicking evolutionary processes. Analysis is performed for the engineered metasurface responses for frequency-selectivity, absorption, rasorber characteristics, and photonic nanojet generation.

Fall leads to major injuries, physical disability and sometimes death. Therefore, there is a need to design a dependable embedded system device which will help in detecting the fall and further sends an emergency notification and thus helps in preventing the fall. Many researchers have considered human fall as an unpredictable danger to the life of older generation. Hence lot of research has been done in this area to develop a fall detection system. The existing fall detection systems are efficient but they lack in sensor optimization, early fall detection and efficient wireless communication. In this study, we have demonstrated a pre-fall detection system which detects human falls approximately 250 ms before it occurs. Early fall detection helps in preventing the subject from serious injuries. The designed system monitors user balanced and unbalanced state. Once the unbalance state is detected the system signifies it as a fall, thus gives milliseconds of time to trigger the safety devices like wearable airbag worn by a subject. On fall the system sends emergency notification to the care taker using either Internet of things (IoT) or Bluetooth low energy (BLE). The Hardware system is designed such that it consumes low power and it is a dependable embedded system with easy to wear capabilities for the subject. The designed system uses Arm Processor associated with motion sensors, communication sensors, Signal sensor and MicroSD Card. The software and hardware combination was developed to get optimal low power consumption by switching the CPU between active and sleep mode. The practical experiments performed on the designed system results in giving the 100% sensitivity and 98.07% specificity for fall detection. The wireless communication is efficiently designed such that the power is consumed only when the fall is triggered. The designed system acknowledges the difference between activity of daily living (ADL) like walking, sitting running, and climbing stairs with actual fall.","PeriodicalId":306091,"journal":{"name":"2017 IEEE National Aerospace and Electronics Conference (NAECON)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128697303","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 system is capable of minimizing cross-talk between multiple channels of amplifiers arranged on one chip using guard rings. Graphene mono-layer is utilized as sensing material and the sensitivity is catalyzed by addition of Gold nano-particles on its surface. The signal from the sensing unit is received by an offset cancellation amplifying system using an SoC approach. Internet of things capability of the sensing device is performed using FRDM K64f micro-controller board which sends message on IBM Bluemix IoT platform when a gas is sensed. The message is received by an application created and sent as an email or message to the user. The paper details the mathematical models of the gas sensing devices, and the interface circuitry that drive the differential potentials, resulting from the sensing unit. The paper presents the middle phase of a long-term project, detailing the design approach of the processing unit within the SOC system and wireless implementation of it. The gas sensor is tested for various sensing configurations. Resistive sensing was found to be sufficient for providing reference data for a sensor matrix to be designed. The change in resistance threshold values are populated in the multi-dimensional matrix. Based on sensed change in resistance values, the gas detected can be identified from the matrix. Sensing data is then sent to IBM Bluemix IoT platform using FRDM K64f development board. The information is sent in a form of packet.","PeriodicalId":306091,"journal":{"name":"2017 IEEE National Aerospace and Electronics Conference (NAECON)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125856078","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}

Described as an “avalanche” of electrons in radio frequency (RF) and microwave devices under vacuum, multipactor is caused by repeated secondary electron emission (SEE) stimulated by a time-varying electric field. Its effects range in severity from a temporary disruption in device operation to arcing, melting, cracking, or destruction of the device. A new and promising field of multipactor suppression research is engineering the internal surface topography of a VED to limit the secondary electron yield (SEY) to unity or less. Such low values of SEY render impossible the growth in electron population that is necessary to initiate the electron avalanche in a multipactor. We have developed a new model to predict the SEY of a porous surface which is useful to determine optimal topographies to control SEY. In order to assess how porous surfaces will be effected by extreme temperatures encountered in space we performed thermomechanical simulations of single gold pores. Finally, we discuss the design and fabrication of various microporous and nanoporous surfaces that will be used to validate the model in a future experimental SEY study.","PeriodicalId":306091,"journal":{"name":"2017 IEEE National Aerospace and Electronics Conference (NAECON)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128171124","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}
