Firstly, modes overlapping occurs easily between Near Infrared spectral high frequency signal and noise, so the Ensemble Empirical Mode Decomposition(EEMD)method was used to remove the noise. According to the approximate completeness of Near Infrared spectrum, an EEMD denoising method based on normalized index optimization. This method views the global optimal point of normalized denoising index as stop condition, and completes itself adaptively with no parameters setting during the decomposion. It can be concluded by Near Infrared spectrum denoising data that this method improves the denoising accuracy and decreases the difficulty in operation in an easy and efficient way. © 2016 SERSC.

This work presents a non-Karp-Miller tree called a lean reachability tree (LRT). It does not try to equivalently represent but faithfully express in a finite manner the reachability set of an unbounded Petri net. First, we derive a sufficient and necessary condition of unbounded places and some incremental reachability properties to characterize unbounded nets. Then, we present a sufficiently enabling condition (SEC) and an LRT generation algorithm. No fake marking is produced and no legal marking is lost during the tree generation. We prove that LRT can represent faithfully the reachability set of an unbounded net in a finite manner. Also, we examine its properties and prove a sufficient condition for deadlock checking based on it. Our examples show that LRT outperforms the latest modified Karp-Miller trees in terms of size, expressiveness, and applicability.

It is very important to study LBS (Location-based Service) personal location inference for the privacy protection and the value extraction of LBS big data. According to study the characteristics of the target user's state in day view belongs to Gaussian distribution, an effective method to infer the user's home and work location is proposed in the article. Experimental results show that the inference method based on the user's state distribution has the higher inference accuracy than the current inference method based on the frequency statistics.

The paper presents an application of probabilistic model to describe a radio propagation delay in indoor environment. Model is based of delta functions sequence to describe retransmissions between a transmitter and a receiver. Theoretical considerations have been verified by measurement results obtained by using the experimental system developed for investigating delays caused by external disturbances influencing the wireless transmission. One of such a commonly occurring disturbances are walls in building where the radio signal is propagating.

This paper focuses on finding out a optimum quadrature error correction method for a dual-mass Micro-electro-mechanical System (MEMS) gyroscope with quadrature error correction combs and sense feedback combs. The structure of the gyroscope was introduced, and influences of quadrature errors on the output signals were simulated and quantized. The results show that quadrature error equivalent angular rate is 200(°)/s and the demodulation phase error is less than 2°, which generates 15(°)/s variation of output signal. Three kinds of quadrature error correction methods used commonly in measuring this structure were investigated, and they are Charge Injecting Method (CIM), Quadrature Force Correction Methods (QFCM) and Quadrature Coupling Stiffness Correction Method (QCSCM). The feasibility of the three method was verified in theory. A gyroscope without quadrature error correction was tested, the results show that the quadrature signal peak-peak amplitudes from left and right mass preamplifiers are 150 mV and 300 mV respectively. Then, the correction method based on left mass and right mass independently was proposed. The the experiments based on CIM, QFCM and QCSCM were performed. The results show that the quadrature error signals are eliminated basically, their bias values and bias stabilities are -8.361(°)/s and 423(°)/h, 2.419(°)/s and 82(°)/h, 1.751(°)/s and 25(°)/h, respectively. According to the results, the QCSCM is verified to be the optimal method for quadrature error correction, and the theory analysis result is correct. © 2016, Science Press. All right reserved.

In this paper, we propose novel relay selection policies that aim at reducing the average delay by incorporating the buffer size of the relay nodes into the relay selection process. More specifically, we propose two delay-aware protocols that are based on the max - link relay selection protocol. First, a delay-aware only approach while it reduces the delays considerably it starves the buffers and increases the outage probability of the system. Towards this end, we propose a delay- and diversity-aware buffer-aided relay selection policy that aims at reducing the average delay considerably and at the same time maintaining good diversity. The protocols are analyzed by means of Markov Chains and expressions for the outage, throughput and delay are derived. The performance and use of our proposed algorithms is demonstrated via extensive simulations and comparisons.
