ZigBee sensor nodes of a Wireless Body Area network (WBAN) are implanted in or equipped on a person's body. These nodes are employed to transmit important physiological or motion parameters. This wearable healthy telemonitoring system makes the guardians out of the complex wired connection, as well as brings convenience to hospitals and patients for long-term remote monitoring. However, while enjoying...
Multi-label learning has received significant attention in the research community over the past few years. Traditional supervised learning techniques do not fit it well, as real-world objects might be complicated and have multiple semantic meanings simultaneously. In our work, we set our goals to mine the involved product attributes in comment data from JD.com. This task is fundamental and significant...
In this paper, we propose a three-stage reconfigurable topology synthesis approach for Application-Specific NoC (ASNoC) on partially dynamically reconfigurable FPGAs, where the topology is reconfigured dynamically at run-time along with the application’s execution. Firstly, given the scheduling and floorplanning of task modules, an Integral Linear Programming (ILP)-based method is proposed to partition...
With the development of OTT (Over The Top) application, cell phone users have to pay more for their Internet access. To help these users save their 3G/4G communication in smart phone, a number of Apps have been upgraded to provide none-graphic model. However, the QoS of Internet service is weakened under this model. This paper proposes an innovative method by analyzing the user's Web access pattern...
Information privacy for Wireless body area network (WBAN) includes the user's physiological parameters. When a user of WBAN system intends to query medical data, the security issue is involved. Ciphertext retrieval technology is an effective way to ensure this confidentiality. However, efficiency and accuracy for data retrieval are challenges under the consideration of the aggregation of medical data...
Body-centric system which is generally used for monitoring and tracking is a technology involving RFID communication system. Currently, many researchers have investigated textile RFID tags integrated in the garments, however, few of them studies the wearable reader antenna. In this paper, a 1.8GHz textile dual-polarized antenna, which will be potentially used as a reader antenna, was designed and...
The purpose of the present study is to prepare a diatrizoate meglumine-loaded chitosan microsphere, which could be used to be investigated by ultrasonic imaging technique in vivo and would has water absorption swelling property to dredge the obstruction. Diatrizoate meglumine-loaded chitosan microspheres were prepared by crosslink emulsification process, to use chitosan acetic acid solution as aqueous...
In a wireless body area sensor network (WBAN), biosensors are implanted or worn on an individual to acquire medical data for a clinical diagnosis or physical monitoring. Traditionally, authentication and cryptography techniques are used to achieve the data confidentiality and privacy of a WBAN system. However, for WBAN systems, besides data itself, the pattern of data transmission may leak critical...

Feature selection is important for classification problem, especially when the number of features is very large or noisiness is present in data. Support vector machine (SVM) with Lp regularization is a popular approach for feature selection. Many researches have devoted to develop efficient methods to solve the optimization problem in support vector machine. However, to our knowledge, there is still...
In a Wireless Body Area Network (WBAN), biosensors are implanted or worn in/on an individual to acquire medical data for a clinical diagnosis or physical monitoring. To achieve confidentiality and privacy of a WBAN, authentication and crypto contribute a lot. However, besides data itself, the pattern of data transmission contains more secretes than it seems to. Various medical sensors deliver data...
In order to comparing fragility index and the influential factors of State-owned Commercial Bank, Joint-stock Commercial bank, City Commercial Bank and Rural Commercial Bank, CAR, NPLR, ROA, ROE and C/D are chosen to make up fragility index of systems of the four commercial banks respectively by combination of FCE & AHP from 2001 to 2010 in this research. Influential factors of fragility analyzed...
In wireless sensor networks, there exist many redundant sensor nodes, and activating only the necessary number of sensor nodes at any particular moment can save energy, while ensuring all targets covered and network connectivity. In this paper, we first introduce a distributed scheme for sink nodes to find K paths to each sensor nodes. Secondly, a shortest-path-based algorithm is presented for the...
the research makes quantitative analysis of the volatility of SHIBOR based on the mainly four interest rates through the family of GARCH models by Eviews 6.0. Empirical results show that the family of GARCH models eliminates correlation of the original overnight interest rate and 1-week interest rate series successfully, and there is an obvious reversions in the asymmetric behavior of the volatility...
In wireless sensor networks, how to detect the malicious nodes and prevent them from attacking the normal nodes has become one of the most important issues. This paper introduces a new mechanism in which the sensor nodes collaborate with each other to resist denial of service (DoS) attack and protect the being attacked nodes. A reputation-based incentive model for cooperation is also proposed. Simulation...
This article discussion on how to cultivate engineering innovative talents from the aspects of the significance of the cultivation of innovative talents, training mode, innovation education, construction of talent training system. It serve as a prerequisite for training qualified applied innovative talents of engineering. Made a reliable foundation for the next formulation and implementation more...

The evaluation index system and subordinate function and weight proportion are defined. An example of fuzzy evaluation for online...
This paper focuses on the optimization of location inventory routing problem (LIRP) taking the retailers' customer time satisfaction degree into account. Based on the model of LIRP, a multi-objective programming model of LIRP which accounting to customer time satisfaction degree is built. Then an improved genetic algorithm is introduced to solve the model. Finally, a set of computational experiments...
The simulated and experimental results of a tunable microstrip ring bandpass filter are presented in this paper. A meander path is loaded in the ring resonator for achieving different resonator lengths by using the ON or OFF state of PIN diodes and then switch the passband from 2.47GHz to 5.1GHz. When the PIN switch turns to ON state, which is equivalent to a resistance, the bandpass filter has a...
A novel textile two-element array antenna with special structure at 1.5GHz is introduced. The patches, the substrate and the ground are woven together as a unity. The measured results agree well with the simulated ones, and the measured gain is 6.4dB, showing the usability of the new generation of textile antennas.
