Marine radar can be applied to detect oil spill targets in a large range, which cannot be affected by night, cloudy, rain, snow and other inclement weather. It has played an important role in the field of oil spill monitoring. Moreover, marine radar has the advantages of low cost and convenient installation, which is suitable for constructing marine oil spill network monitoring system. Taking marine...
Freezing of gait (FoG) is an aberrant gait in Parkinson's disease (PD), which is usually associated with fall risks and reduction of patients' life quality. Efficient intervention for patients to remove FoG has been proposed using context-aware rhythmic auditory cueing during FoG episodes, which relys on accurate detection of FoG. And clinical diagnosis of PD is partly based on the severity of FoG...
The switching in of renewable resources to micro-grids and the implementation of demand response strategy has made reliability evaluation of micro-grid become increasingly complex. This paper focuses on the influence of demand response strategy on micro-grid's reliability. The coordination degree between the micro-grid's new energies and loads can influence micro-grid's reliability and the utilization...
In order to study the influence of electrical collector system of wind farm from the perspective of four typical topological structures of electrical collector system of wind farm, sequential Monte Carlo model is established for reliability evaluation of electrical collector system of wind farm with consideration of multiple faults of wind turbine generator (WTG) and collection circuit in wind farms...
Despite the growing deployment of 4G networks, the capacity of cellular networks is still insufficient to satisfy the ever-increasing bandwidth demand of mobile applications. Given the common interest of mobile users, Device-to-Device (D2D) communication has emerged as a promising solution to offload cellular traffic and enable proximity-based services. One of the main detriments for D2D communication...
To evaluate the national military development situation, is not only to systematically grasp their own strength and security situation of the country, but also to compare and analyze the degree of the countries' future military construction. Based on the net assessment method, this paper established the evaluation index system of national military development, used the application of statistical methods...
This article focuses on the study of detecting key individuals in terrorist network, combining the theories and algorithms of Social Network Analysis (SNA), Multi-meta Network Analysis and Fuzzy Analytical Network Process (FANP). Firstly an index system is built and then within this system the scores of terrorists are calculated, referencing the measures (total degree, betweenness, closeness, etc)...
This paper reports a novel whispering gallery mode photonic dual-disk resonator (DDR) with enhanced quality factors. The second disk with the same dimension as the primary disk enhances the coupling efficiency of the bus waveguide and the disk resonators. The compact disk design brings the possibilities of smaller device dimension and large integration of optical circuits on a chip. The measured result...
The task of visual vocabulary construction plays an important role in the bag-of-words based pattern analysis and robotic applications. A discriminative vocabulary generation in unsupervised case is an open issue for reducing perceptual aliasing in image matching based applications. In this paper, we present a scheme to evaluate the discriminative power of each visual word quantitatively in terms...
The reasonable dispatching is a key part in maintaining security and stability of power system. Due to the uncertainties such as weather and equipment aging, dispatching operation often faces certain risks. It is essential to analyze the real-time risk of dispatching operation to ensure that the risk can be controlled before dispatching orders are carried out. In this paper, risk theory is implied...
We consider the problem of elastic-demand network equilibrium in communication networks which support both multirate multicast sessions and unicast sessions. Extending existing work for unicast sessions, we first present the elastic-demand network equilibrium models in different multicast sessions, which can be formulated as a convex programming problem. To solve the convex programming problem we...
In sensor networks, skeleton (also known as medial axis) extraction is recognized as an appealing approach to support many applications such as load-balanced routing and location free segmentation. Existing solutions in the literature rely heavily on the identified boundaries, which puts limitations on the applicability of the skeleton extraction algorithm. In this paper, we conduct the first work...
In this paper, we propose two novel schemes, which are based on our proposed novel fractional order memory polynomial pre-distorter, to conduct the digital base-band power amplifier pre-distortion with the improvement of power amplifier efficiency. For the first scheme, fractional order terms are included in the conventional memory polynomial containing the odd and even order polynomial terms. For...
A new technique, introducing current starving into power rail ESD design, is presented and verified in this paper. To achieve the turn-on time requirement of the power rail ESD clamp circuit in a certain time, a smaller capacitor value will be permitted by which the current starving is used. Besides, PMOS keeper architecture is adopted in order to achieve low power leakage. Eventually, combining current...
Deployment of heterogeneous networks is one of the key technologies in LTE-Advanced. After low-power nodes were introduced to cellular system, great changes have taken place in the structure of traditional networks. Thus, range expansion (RE) scheme is proposed to adapt to these changes in the standardization process of heterogeneous networks. This paper studies the performance of heterogeneous networks...
Owing to the stagnant reclaimed water utilization we faced today, rational reclaimed water price is researched in the paper so as to accelerate the popularization of reclaimed water. A fuzzy synthetic assessment model based on improved entropy weight method is established with an index system including natural water contamination index, water poverty index, economic synthetic index and reclaimed water...
On the basis of the function and significance of performance evaluation of college political instructors, and by the principle of performance evaluation, the performance evaluation index system of the college political instructors was established in three aspects, including working philosophy, daily work and academic research, and the mismatch between performance evaluation index system of the political...
RFID promises to revolutionize the inventory management in large warehouses, retail stores, hospitals, transportation systems, etc. Periodically reading the IDs of the tags is an important function to guard against administration error, vendor fraud and employee theft. Given the low-speed communication channel in which a RFID system operates, the reading throughput is one of the most important performance...
