The number and variety of cyber-attacks is rapidly increasing, and the rate of new software vulnerabilities is also rising dramatically. The cybersecurity community typically reacts to attacks after they occur. Being reactive is costly and can be fatal, where attacks threaten lives, important data, or mission success. Taking a proactive approach, we are: (I) identifying potential attacks before they...
Due to its own features including variability of network topology, instable vehicle density and so on, Vehicular Ad hoc Networks (VANETs) can hardly guarantee efficient and reliable network connectivity which plays an important role in data dissemination. Compared with VANET, cellular networks is of great advantage to provide timely data propagation. To solve the problem of disconnection in VANET,...
The super-resolution reconstruction is an important method for improving the image quality, and the objective world can be better understood from 3D super-resolution model than from 2D images. In this paper, the image super-resolution reconstruction algorithm based on wavelet and the 3D geometric modeling technology were combined to study the 3D super-resolution reconstruction of images. Firstly,...
In order to meet the increasing demand of data rate, the next generation Mobile Communications (5G) are becoming more heterogeneous, irregular and complex. This will lead to more complex interference environment. So the traditional fixed geometry hexagon model is no longer applicable. In order to more accurately evaluate the performance of the 5G heterogeneous network, in this paper, we proposes to...
Spectrally Efficient Frequency Division Multiplexing (SEFDM) systems provide enhanced spectrum utilization compared with Orthogonal Frequency Division Multiplexing (OFDM) systems by relaxing the orthogonality condition among sub-carriers. However, in the SEFDM systems, the loss of orthogonality results in the inter-carrier-interference (ICI) thus reduces the transmission reliability. To alleviate...
Traditional GPSR and its enhanced protocols make forwarding decision only basing on one specific segment of the neighborhoods, thus the Successful Date Rate (SDR) often seems unpleasing. And the constant beacon interval always cause data collisions when the vehicle densities meet a high level. To solve the problems, we introduce a concept - the Coefficient of Dependence (CoD), to describe the contribution...
As a data exchange specification for industrial communication, OPC Unified Architecture (OPC UA) solves the access uniformity and standardization problem of data communication between the plant floor and the enterprise, and meets the needs of enterprise information in a high degree of connectivity. OPC UA protocol can be extending to the low-layer of the industrial wireless network systems, and then...
WIA-PA (Wireless Networks for Industrial Automation-Process Automation) standard has become one of the three major IEC (International Electrotechnical Commission) standards for industrial wireless networks technology, and multi-channel frequency hopping mechanism is significant for the performance of WIA-PA networks. Existing AFH (adaptive frequency hopping) mechanism for WIA-PA networks is based...
A novel thermal sensor is designed and fabricated based on spin-transfer torque operated magnetic tunnel junction (STT-MTJ) device. It can fulfill thermal detection and overheat protection on integrated circuit. Moreover, it shows over 10 times faster thermal transit response speed than that of traditional CMOS thermal sensor. The unique property is really helpful for controlling integrated circuit's...
In this paper, we introduce a new model for RF-powered cognitive radio networks with the aim to improve the performance for secondary systems. In our proposed model, when the primary channel is busy, the secondary transmitter is able either to backscatter the primary signals to transmit data to the secondary receiver or to harvest RF energy from the channel. The harvested energy then will be used...
In order to increase the accuracy for the diagnosis of schizophrenia (SCZ) disease, it is essential to integratively employ complementary information from multiple types of data. It is well known that a network is a graph based method for analyzing relationships between patients, with its nodes and edges representing patients and their relationships respectively. In this study, we developed a network-based...
Schizophrenia (SCZ) disease ranks among the top 10 causes of disability in developed countries worldwide. Its onset is the combination result of genetic, biological and environmental factors. It is increasingly important but difficult to determine which genes are potential biomarkers for SCZ, owing to the complex nature of the pathophysiology of this disease. In our study, we integrated genomic, epigenomic...
Kernel and Multiple Kernel Canonical Correlation Analysis (CCA) are employed to classify schizophrenic and healthy patients based on their SNPs, DNA Methylation and fMRI data. Kernel and Multiple Kernel CCA are popular methods for finding nonlinear correlations between high-dimensional datasets. Data was gathered from 183 patients, 79 with schizophrenia and 104 healthy controls. Kernel and Multiple...
A fractional-N PLL employing a dual-frequency clock generator is proposed to achieve lowering the in-band phase noise. The architecture enables the PFD/CP to operate in the linear region to avoid noise-folding effect. An optimum operating condition can be tuned to achieve the best in-band phase noise. The proposed techniques are employed in a 800-MHz fractional-N PLL fabricated in a 0.18-μm CMOS process...
This paper presents an approach to assess the economics of customer-sited energy storage systems (ESSs) which are owned and operated by a customer. The ESSs can participate in frequency regulation and spinning reserve markets, and are used to help the customer consume available renewable energy and reduce electricity bill. A rolling-horizon approach is developed to optimize the service schedule, and...
Most existing approaches for solving the network threat problems focus on the specific security mechanisms, for example, network intrusion detection system (NIDS) detection, firewall configuration, rather than on flow management approaches to defend network threats with an SDN (Software Defined Networking) architecture. Accordingly, this study proposes an improved behaviour-based SVM (support vector...
Basic principles of drug development, gene sequencing and bioinformatics, application of biotechnology information to medicine, application of biotechnology information to nonmedical markets, and the regulatory environment altogether with industrial classification of biotechnology industry’s pharmaceutical manufacturing and biotechnology industry’s pharmaceutical SIC subcategory under US EPA’s guidelines...
