We present a model and a hypothesis testing based framework for determining genuinely good service providers from the ratings given to them by customers, allowing ratings to be imperfect representations of the service provided. The problem is complicated because the nature of the customer that rates the service provider affects the reliability of the rating, but this nature is not known a priori and...
In this paper are presented the results obtained after of evaluating three techniques of blind detection of spectrum holes used in Cognitive Radio (CR). The techniques evaluated correspond to the general technique of detection of energy levels, the method LAD BASED and the technique based on forward methods. The operation of these techniques was tested in simulation scenarios of a telecommunications...
Anthropogenic underwater sound is now recognized as a world-wide problem. Shipping, seismic surveys and pile driving, among some other human activities, have shown a broad range of negative effects in a variety of species. It is thus important to control, register and characterize these activities in order to establish policies that mitigate its effects. For this purpose, automatic detectors of the...
The transport type metal detector balanced differential transmission coil to detect metal particles. In the process of industrial production, other metal production equipment, transmission belt of steel and other external factors are influenced by the test. Repeated experiments can reduce the interference, but will affect the production efficiency, this paper provides a more efficient and effective...
In this paper, a low-power four-quadrant current multiplier based on the electronically and linearly tunable CMOS transconductors (EOTAs) is presented. The design technique is realized by using only two EOTAs as active circuit elements. The proposed current multiplier can operate for four quadrants with wide input dynamic range. The performances of the proposed current multiplier are tested on PSPICE...
Estimation of density and direction of crowd flow from surveillance video has attracted much research attention recently in the area of computer vision. Crowd density in a video sequence can be considered as a global entity to estimate the direction of interest of the crowd. Though there are methods to compute the density and direction, a combined approach will give more insights into the problem...
The characteristics of quantum channel play important roles on designing a high performance quantum communication system. In this paper, we analyze the fidelity of polarization state travelling through a non-Markovian optical fiber depolarizing quantum channel with color noise environment. The quantum bit error rate (QBER) of a polarization coding BB84 quantum key distribution (QKD) system under non-Markovian...
This paper studies the design and detection issues of false data injection (FDI) attacks against output tracking control systems from the perspectives of defenders and attackers, respectively. Based on a state-space model, an output tracking control system is designed by using a Kalman filter and an augmented state linear quadratic Gauss optimal control feedback control strategy. For such a control...
The tremendous growth in the availability of texture+depth(RGBD) content has motivated researchers to focus into the area of features that uses geometrical information given by depth. These features are more efficient and robust than the existing 2D features under large variations in camera viewing angles. In this paper, the performance evaluation of the keypoint detector for two views of a scene...
The goal of this paper is to serve as a guide for selecting a detection architecture that achieves the right speed/memory/accuracy balance for a given application and platform. To this end, we investigate various ways to trade accuracy for speed and memory usage in modern convolutional object detection systems. A number of successful systems have been proposed in recent years, but apples-toapples...
Fiber Optic Gyroscope is an optical sensor that can determine the position of the angle of motion of an object. FOG works based on the Sagnac effect, which states that the phase shift between two opposite waves propagates in the interferometry of the rotating ring, and proportional to the angular velocity. Goodness performance indicator of measurement system, is having a small noise. Angle Random...
The Visible-Infrared Imaging Radiometer Suite (VIIRS) onboard the Suomi National Polar-orbiting Partnership (S-NPP) spacecraft as a primary sensor was launched October 28, 2011. There are 22 VIIRS bands: 7 thermal emissive bands (TEBs), 14 reflective solar bands (RSBs) and a Day Night Band (DNB). An on-orbit On-Board Calibrator BlackBody (OBCBB) is used as the TEB calibration source that tracks the...
We report a highly-sensitive plasmonic nano-ring transistor for monolithic terahertz (THz) active antenna. By designing an ultimate asymmetric transistor on a metal-gate structure, more enhanced (180 times) channel charge asymmetry has been obtained in comparison with a bar-type asymmetric transistor of our previous work. In addition, by exploiting ring-type transistor itself as a monolithic circular...
This paper presents a novel location strategy for traffic emission remote sensing system (TERSS) based on bus routes. For the purpose of reducing cost, the corresponding Hypergraph Model is established based on graph theory and the topological structure of urban road network. Then, the location problem of traffic emission remote sensing detectors is defined and transformed into finding the minimum...
Constrained Local Models (CLMs) are a well-established family of methods for facial landmark detection. However, they have recently fallen out of favor to cascaded regressionbased approaches. This is in part due to the inability of existing CLM local detectors to model the very complex individual landmark appearance that is affected by expression, illumination, facial hair, makeup, and accessories...
Deep Convolutional Neural Networks (CNN) are the state-of-the-art performers for the object detection task. It is well known that object detection requires more com- putation and memory than image classification. In this work, we propose LCDet, a fully-convolutional neural net- work for generic object detection that aims to work in em- bedded systems. We design and develop an end-to-end TensorFlow(TF)-based...
A source of entangled photons is connected via optical fibers to two single photon detectors. By simultaneously measuring pump power dependencies of the detection probabilities at each detector, as well as the probability of coincidence counts, we reliably extract all relevant system parameters.
Efficient and robust detection of humans has received great attention during the past few decades. This paper presents a two-staged approach for human detection in RGB-D images. As the traditional sliding window-based methods for target localization are often time-consuming, we propose to use the super-pixel method in depth data to efficiently locate the plausible head-top locations in the first stage...
With the rise of end-to-end learning through deep learning, person detectors and re-identification (ReID) models have recently become very strong. Multi-target multicamera (MTMC) tracking has not fully gone through this transformation yet. We intend to take another step in this direction by presenting a theoretically principled way of integrating ReID with tracking formulated as an optimal Bayes filter...
Modern wireless communication raise the demand for higher spectral efficiency, faster-than-Nyquist (FTN) signaling is able to increase transmission rate without expanding signaling bandwidth. In this paper, we develop a graph-based iterative FTN detector in the presence of phase noise (PHN). Wiener process is employed to model the time evolution of nonstationary channel phase. The colored noise imposed...
