As a main coaxial cable connector, BNC connector, internal connections of which often take the form of a clamping structure, is widely used in communication industry. Due to different manufactures' different production processes and standards, inadequate compaction or out-of-tolerance component size in BNC connector production may cause poor contact, which may lead to mismatch loss of coaxial cable...
In this paper, we discussed about a new mobile robot navigation technique, which will be used for home security. The objective is to perform indoor navigation efficiently and at the same time make the cost of the device as low as possible so as to make it commercializable. Here, we proposed an approach based on recognition of two infrared generated ceiling spots, which remains invisible to human eyes...
An internal model control method based on inverse system to improve vehicle stability was proposed. The inverse model approximated by neural network was cascaded with the original system in the method. Based on the idea of the inverse system method, the obtained system was controlled by the method via feedback linearization. A simulation is performed with it during two different conditions: step input...
Infrared moving target tracking algorithm in complex background prone target loss problems, proposed to add background perception module and target feature matching function in tracking algorithm, real-time analysis of the surroundings of the target. Strict constraints target infrared feature matching function when found that the background will be changed, if the target is interference, and outputs...
Transactional Memory (TM) is an attractive concurrency control mechanism that should deliver much better performance than locks in case when transaction conflicts are rare. But, if the probability of conflicts is high, TM program performance may be very poor. Therefore, when engineering mission critical systems, we need to be able to calculate conflict probabilities. In this paper we study a class...
This paper considers the independent component analysis (ICA) case in blind source separation (BSS), in which observations result from the linear and instantaneous mixture of sources. Inspired from the recently proposed reference-based contrast criteria, a similar contrast function is proposed, based on which novel optimization algorithms are proposed. They are very similar to the former classical...
In this paper, we briefly analyzed the advantages of passive distance measurement based on Wireless Fidelity (WiFi). Based on the analysis of the principle of traditional interferometer direction finding, we derived the equations which are suitable for indoor distance measurement. Through theoretical analysis and simulation, we prove the correctness of the equations. Finally, we analyze and conclude...
To solve the problem of quantitative and qualitative information exchange in the process of fast and accurate identification on road network traffic status, which is also known as automatic congestion identification (ACI) problem, a recognition algorithm based on cloud mode with three-level road network traffic state is proposed l. This paper focuses on solving several key problems about the concept...
In the paper, the widely used numerical optimization method for linear frequency modulated (LFM) signal parameters estimation is modified. To this purpose, an improved Dividing RECTangles (DIRECT) algorithm is proposed to substitute for the commonly used grid search method. The proposed global optimization algorithm can provide initial estimates for local optimization algorithms such as Newton and...
Bus passenger flow collection technology is a subject urgently to be solved in current city intelligent transport system construction. By using self-developed multi-sensor array devices to collect the foot type data of passengers getting on and off, a kind of bus passenger flow intelligent recognition and statistical algorithms based on motion vector tracking is researched and proposed. The basic...
A model for Chinese medicine sugar precipitation is designed, without considering crystal size distribution. Adaptive robust control algorithm is presented for the uncertain nonlinear system based on Lyapunov's stability theory. The kernel idea is model decomposition: adaptive control algorithm is designed for attenuating the parameter uncertainties; robust control algorithm is designed for eliminating...
The improved partial proportional fair (IPPF) algorithm for OFDMA relay system is proposed, aiming at solving the fairness scheduling problem. Subcarriers are distributed to all users in both two sub-timeslots. And the relay users are regarded as two users in the subcarrier scheduling for the second sub-timeslot, so as to balance the data rates of all users. The IPPF algorithm achieves a better balance...
Cognitive radio (CR) is a promising technology that enables opportunistic using of the unused spectrum to alleviate the spectrum scarcity problem. However, as the interference to licensed spectrum owners needs to be strictly controlled, CR enabled users (CRs) should vacate the using channel immediately on detecting licensed users activity and the end to end performance may be seriously degraded. In...
Moral hypocrisy is a phenomenon in which individuals evaluating other people's moral transgressions differ from their evaluations of the same transgressions enacted by themselves. The present study examined whether there is a moral hypocrisy when participants take different roles in moral dilemma. We found that although participants' decisions were no different when they taking different roles in...
The Lorentzian hard thresholding pursuit algorithm is proposed in this paper to achieve efficient reconstruction for compressed sensing in the presence of impulsive noise. In the Lorentzian hard thresholding pursuit algorithm, the minimum LL2 norm problem is solved with respect to a support which is obtained through the hard thresholding operator. The convergence and reconstruction performance of...
Keyword search technique over relational databases is a research hot-spot in database field. At present, there have been many ranking correlation algorithms for object-level keyword search over relational databases. Object-level keyword search can better integrate information scattered in various tuples. OCS(Object-level Correction Sort) algorithm cannot rank results in keyword search accurately as...
This research work demonstrates a performance-based approach to evaluate the quality performance of group buying websites under uncertainty. Linguistic variables are assigned with values using triangular fuzzy numbers approach for effectively modeling the vagueness and imprecision of the decision making process. An effective algorithm grounded on the deviation degree and absolute area of a fuzzy number...
