Comprehensive Border Bases for Zero Dimensional Parametric Polynomial Ideals

In this paper, we extend the idea of comprehensive Gr\"{o}bner bases given by Weispfenning (1992) to border bases for zero dimensional parametric polynomial ideals. For this, we introduce a notion of comprehensive border bases and border system, and prove their existence even in the cases where they do not correspond to any term order. We further present algorithms to compute comprehensive border bases and border system. Finally, we study the relation between comprehensive Gr\"{o}bner bases and comprehensive border bases w.r.t. a term order and give an algorithm to compute such comprehensive border bases from comprehensive Gr\"{o}bner bases.Comment: 15 pages, 8 sections and 3 algorithm

DxNAT - Deep Neural Networks for Explaining Non-Recurring Traffic Congestion

Non-recurring traffic congestion is caused by temporary disruptions, such as accidents, sports games, adverse weather, etc. We use data related to real-time traffic speed, jam factors (a traffic congestion indicator), and events collected over a year from Nashville, TN to train a multi-layered deep neural network. The traffic dataset contains over 900 million data records. The network is thereafter used to classify the real-time data and identify anomalous operations. Compared with traditional approaches of using statistical or machine learning techniques, our model reaches an accuracy of 98.73 percent when identifying traffic congestion caused by football games. Our approach first encodes the traffic across a region as a scaled image. After that the image data from different timestamps is fused with event- and time-related data. Then a crossover operator is used as a data augmentation method to generate training datasets with more balanced classes. Finally, we use the receiver operating characteristic (ROC) analysis to tune the sensitivity of the classifier. We present the analysis of the training time and the inference time separately

Optimal Detection of Faulty Traffic Sensors Used in Route Planning

In a smart city, real-time traffic sensors may be deployed for various applications, such as route planning. Unfortunately, sensors are prone to failures, which result in erroneous traffic data. Erroneous data can adversely affect applications such as route planning, and can cause increased travel time. To minimize the impact of sensor failures, we must detect them promptly and accurately. However, typical detection algorithms may lead to a large number of false positives (i.e., false alarms) and false negatives (i.e., missed detections), which can result in suboptimal route planning. In this paper, we devise an effective detector for identifying faulty traffic sensors using a prediction model based on Gaussian Processes. Further, we present an approach for computing the optimal parameters of the detector which minimize losses due to false-positive and false-negative errors. We also characterize critical sensors, whose failure can have high impact on the route planning application. Finally, we implement our method and evaluate it numerically using a real-world dataset and the route planning platform OpenTripPlanner.Comment: Proceedings of The 2nd Workshop on Science of Smart City Operations and Platforms Engineering (SCOPE 2017), Pittsburgh, PA USA, April 2017, 6 page

A Wideband Microstrip Antenna with EBG Structure and Superstrate

A microstrip patch antenna withEBG structure and a dielectric layer have noteworthy effect on its input characteristics and band width. In this paper we studied both electromagnetic band-gap structure and a superstrate to increasing bandwidth of micrstrip patch antenna. We calculated bandwidth with and without EBG to design an Antenna for resonance frequency 4GHz. And then apply superstrate in EBG structure. This antenna simulated on Ansoft HFSS designer software,impedance bandwidth ,VSWR ,return losses & smith charts are observed and experimentally studied .Details of simulated results are presented and discussed

Study of Challenges Associated with Hybrid Renewable Energy Resources

Due to the fact that solar and wind energy are intermittent and unpredictable, greater penetration of their types into existing power systems, especially weak grids or island systems without adequate and sufficient storage capacity, could cause and create high technical problems . By integrating the two renewable resources in an optimal combination, the effects of the different nature of solar and wind resources can be partially offset and the overall system becomes more reliable and economical to use. This article discusses grid quality problems with grid connected renewable energy sources and grid quality problems are harmonics and voltage and frequency fluctuations as well as a description of grid connected PV generation system in this article
