At present, the detection of mixing uniformity in glass furnace batching system is mainly realized by artificial detection. However, this method is time-consuming and laborious, and there are some risks. For the problem of mixing uniformity detection, the nonlinear relation between the actual weight value and the mixing uniformity is established by the BP neural network, which can predict the mixing...
The default mechanism for a wireless station to select which access point (AP) to associate with is based on the strength of the received signal by the station. This leads to stations associating to the closest AP. In situations where user stations are concentrated around one AP, the default algorithm (DA) results in an unbalanced distribution of station-AP associations. This causes congestion at...
Effectively managing spectrum for an ever increasing wireless world requires an advanced agile and flexible regulatory environment that uses an extensive network of sensing devices to ensure the orderly and secure evolution of new advanced networks and technologies that work free from harmful interference. The Spectrum Environment Awareness (SEA) prototype system currently being developed at the Communications...
Aluminum Nitride (AlN) based Surface Acoustic Wave (SAW) sensors have shown great application potentials on serving as biosensors. In this paper, we investigate the mass sensitivity of SAW sensors, which were fabricated based on Si/AlN structure by depositing aluminum oxide (AhO3) thin films on the active area between the input port and output port of the SAW devices. The material of the IDTs is aluminum...
This paper describes a method to find a least-cost path for water diversion planning in the high-altitude mountain area by using the GIS techniques. However, existing algorithms could not be used for practical water diversion projects in the China's southwest region. To improve conventional cost path analysis, we first use the heuristic algorithm to build a three-dimensional elevation surface model...
Identifying the functionalities of urban regions helps policy makers to improve resource management and urban planning. In this paper, we propose an improved framework to discover urban functional regions with GPS trajectories and POIs. We construct a spatial proximity model (SPM) by incorporating spatial clustering and co-location patterns into the traditional independent model, and then employ resilient...
In this paper, we analyze the advantages and disadvantages of the proactive QoS routing in ad-hoc networks. We discuss how to support bandwidth QoS routing in OLSR (Optimized Link State Protocol), a best-effort proactive MANET routing protocol. Using OPNET, we simulate the algorithm, exploring both traditional routing protocol performance metrics and QoS-specific metrics. Our analysis of the simulation...
The Aluminum Nitride (AlN) thin film based surface acoustic wave sensors have been fabricated by whole CMOS compatible process. In order to study the resonant frequency behavior responses with temperature, S parameters measured by network analyzer of the AlN SAW sensors are processed with the data extraction program through MATLAB software. It is observed the extracted data of resonance frequency...
This paper uses a modified Ripley's K function to examine the spatial evolution of urban system in the Yangtze River Delta (YRD) of China during the period of 1980–2010. Furthremore, we examine whether coastlines and provincial borders benefit the concentration of city location or size distribution in this region. The results show that: (1) the spatial evolution of the YRD city location distribution...
Physical and social systems can be conceptualized in complexity theory which provides a framework for a refined analysis of local effects on global behaviors. And spatial dynamic models based on discrete time can be referred to as cellular automata (henceforth CA) models, which show advantages for modeling complex systems in a way that is conceptually clearer, more accurate and more complete than...
Based on rough set theory, this paper investigates basic essence in national defence for Chinese university students, and give influencing degrees of some influencing factors with respect to basic essence in national defence.
Proper orthogonal decomposition (POD) method could decompose fluctuating wind pressure into proper mode space-related and principal coordinate time-related. For predicting wind field on structure's surface, this paper worked out a Matlab program decomposing & restructuring wind pressure time interval sequence, which realized its interfacing with the Surfer software whose space interpolation capacity...
Aiming at the slow convergence rate and the high mean square error of constant modulus algorithm(CMA), a new orthogonal wavelet transform based sign decision dual-mode blind equalization algorithm(WT-SDDA) is proposed. In the proposed algorithm, orthogonal wavelet transform based constant modulus algorithm (WT-CMA) is integrated with orthogonal wavelet transform based stop-and-go changeable modulus...
Based on lower approximation operator C1 and upper approximation operator Cmacr1, this paper investigates granularity-wise separations in covering approximation space (U, C), where C1 and Cmacr1 are Zakowskipsilas approximation operators. By these investigations, some characterizations for granularity-wise separations are obtained and some relations among granularity-wise separations are established.
Strategic, operational and tactical information, combat identification and blue-force-tracking provided by advanced "command, control, communications, computers, intelligence, surveillance, and reconnaissance" distributed system-of-systems improve the quality of decision-makers' situation awareness (SA). Such SA improvements increase the pace at which decision making can be done while maintaining...
Aiming at the feature that third-order cumulant of sine stochastic phase signals with quadratic phase coupling is nonzero and that third-order cumulant of sine stochastic phase signals without quadratic phase coupling is zero, square phase dynamic coupling signals, which have to do with time, are defined and analyzed. TSBDALE (third-order cumulant slice-based direct adaptive line enhancer) algorithm...
