Temperature monitoring in the interior of grain warehouse is one of the critical issues for the quality assurance in grain storage depot. Traditional methods, such as sampling inspection or sensor-based temperature data collection in grain warehouse, are usually time-consuming and ineffective because of the low reliability and precision of sensors imbedded in grain stacks. In this article, we develop...
Marine toxins are produced by plankton and do a great harm to human through food chain by accumulating in shellfishes and fishes. It is highly required and favorable to develop novel methods for the rapid and efficient detection of marine toxins to avoid the poisoning cases that have occurred frequently in many countries. This study presents a real-time Love Wave biosensor for the rapid detection...
Recognition of handwritten text is a useful technique that can be applied in different applications, such as signature recognition, bank check recognition, etc. However, the off-line handwritten text recognition in an unconstrained situation is still a very challenging task due to the high complexity of text strokes and image background. This paper presents a novel segmented handwritten text recognition...
Although intensively studied, there is still lack of pathway networks on hematopoiesis effect of Dang-gui (also called Angelica sinensis) that is expressed as “tonify blood” in Chinese medicine. In this study, started from the chemical compounds, proteins targeted by Dang-gui were explored. After that, pathway networks enriched with these targeted proteins were analyzed with hypergeometric distribution...
Probability density function (pdf) estimation of sea clutter in synthetic aperture radar (SAR) imagery has a fundamental role in constructing a constant false alarm rate (CFAR) based ship detector. This paper proposes a semi-parametric sea clutter modeling method for SAR amplitude imagery. The pdf of sea clutter is estimated point by point for each amplitude value, by selecting an optimal component...
This paper proposes a compound feedforward and uncertainty and disturbance estimator (UDE) based control strategy for uncertain systems with Input/Output time delay. The conventional UDE is modified to accommodate the time-delay characteristics. The major aims and modifications of the new structure are: i) to avoid the negative effects of the measurement delay, the predicted process output is calculated...
In active noise control (ANC) system, the injection of white Gaussian noise (WGN) for online feedback path modeling and neutralization (FBPMN) degrades the noise-reduction-performance (NRP). In this paper: (1) a tuning free gain scheduling of WGN is used to improve the NRP of ANC system, and (2) a variable step-size is used to compensate for the decrease in the convergence of FBPMN filter due to gain...
The performance of a tracker can be measured by two often conflicting criteria - robustness and accuracy. Recently researchers have focused on improving robustness, using adaptive appearance models. However updating the appearance model can cause drift and lower the accuracy of motion (state) estimation. These trackers generally compute 2 degree of freedom(DOF) image translation of the object, and...
The mobile social network (MSN) combines techniques in social science and wireless communications for mobile networking. The MSN can be considered as a system which provides a variety of data delivery services involving the social relationship among mobile users. Information diffusion in mobile social networks provides great opportunities for the spread of positive information such as innovations...
In this paper, we study the robustness assessment of power systems. Since the power grid is an electrical network by nature, it can be fully and accurately described by circuit laws. Based on Kirchhoff's laws and the properties of network elements, we propose a complex network model that generates power flow information given the electricity consumption and generation information. It has been widely...
In this paper we present a public dataset to evaluate trackers used for human and robot manipulation tasks. For these tasks both high DOF motion and high accuracy is needed. We describe in detail, both the process of recording the sequences and how ground truth data was generated for the videos. The videos are tagged with challenges that a tracker would face while tracking the object. As an initial...
On-chip many-core systems are expected to be in common use in the future. A set of homogeneous processors in a many-core system can be used to implement multiple pipelines which execute simultaneously. Pipelines of processors use varying numbers of cores when their workloads vary at run time. In this paper, we show how such a system executing multiple pipelines with varying workloads can be implemented...
Mth-band filters have been found numerous applications in multirate signal processing systems, filter banks and wavelets. In this paper, a new closed-form expression is presented for the impulse response of the maxflat R-regular FIR Mth-band filters with arbitrary group delay. The filter coefficients are directly obtained by solving a linear system of Vandermonde equations that are derived from the...
Mobile cloud-computing is a wireless network environment that focuses on sharing the publicly available wireless resources. Wireless network virtualization provides an efficient technique to implement the mobile cloud-computing by enabling multiple virtual wireless networks to be mapped onto one physical substrate wireless network. One of the most important challenges of this technique lies in how...
Recently, both academia and industry are moving their research attention to the fifth-generation (5G) wireless networks — the next new era of wireless networks. The wireless full-duplex transmission, as one of promising candidate techniques for 5G, can significantly boost the spectrum efficiency of the wireless networks, thus providing a powerful thrust to optimize the quality-of-service (QoS) performances...
In large parking lots, it is generally difficult for drivers to know ahead of time whether there will be available parking spots and where they are. Besides, it is logistically cumbersome to wait in line for paying parking fees when leaving. In this demo, we develop an intelligent parking system called iParking. iParking could help users monitor parking states, search for a vacant parking spot, reserve...
In the actual operation of distribution grid with DG, the traditional islanding proection methods do not consider the requirement of low voltage ride through (LVRT) and the cooperation of recloser control. Therefore, the paper proposes a novel islanding protection scheme. Using the position information of the related circuit breakers and the electrical information of PCC of DG, a new islanding detection...
Multiple-input multiple-output (MIMO), which is also known as large-scale antenna system, is a promising technology for achieving the high spectrum efficiency of wireless communications networks. On the other hand, as a smart spectrum sharing technology, Cognitive Radio Network (CRN) is also expected to improve the utilization of spectrum usage for conciliating the current spectrum demand growth....

As compared with 2D wireless camera sensor networks (WCSNs), 3D WCSNs can capture more accurate and comprehensive information for supervisory and military applications. However, 3D WCSNs impose many new challenges for energy-efficiency and interference-mitigation subject to the required coverage rate constraint due to their extensive power consumption for data transmissions and inter-sensor interference...
