Protection and inheriting of the traditional brocade crafts are the focusing problems of the current social. Computer aided design is one of the directions of inheriting the traditional brocade crafts. In this paper, we focus on the Tujia brocade, which is one of the famous Chinese traditional brocade, to research the layout- designing and appearance-simulation techniques. We propose an intelligent design and simulation model of Tujia brocade. The design combination technique based on pattern and skeleton is used to design a digital layout of Tujia brocade. We employ the Octree to quantitate the color map of designed layout and extract the main color map based on kmeans cluster. We render each region, which is segmented by main color map, with yarn structure template based on cubic convolution interpolation algorithm. Finally, we can generate out the appearance of designed layout with good fabric material. To demonstrate the applicability and validity, our method generates several Tujia brocade layouts and simulates its appearance. We also analyze the designed and simulate results compared with some traditional methods.

Outlier-resistant adaptive filtering based on sparse Bayesian learning

In adaptive processing applications, the design of the adaptive filter requires estimation of the unknown interference-plus-noise covariance matrix from secondary training data. The presence of outliers in the training data can severely degrade the performance of adaptive processing. By exploiting the sparse prior of the outliers, a Bayesian framework to develop a computationally efficient outlier-resistant adaptive filter based on sparse Bayesian learning (SBL) is proposed. The expectation-maximisation (EM) algorithm is used therein to obtain a maximum a posteriori (MAP) estimate of the interference-plus-noise covariance matrix. Numerical simulations demonstrate the superiority of the proposed method over existing methods.
Coupled Analysis and Protection of the HTS DC Magnet for DC Induction Heater in Dynamic Disturbance

Designing a high temperature superconducting (HTS) DC induction heater requires the HTS magnet to be equipped with an HTS coil, iron core and air gap. A large amount of magnetic energy is stored in the iron core and must be transferred outside the magnet during system collapses. The nature of the operating conditions and dynamic heating processes make the magnet coil a substantial nonlinear inductive load for the power supply which can result in system collapse and potentially damage the peripheral circuit of the magnet. Therefore, a protection system is recommended for this magnet. This paper proposes an active protection system for a DC HTS induction heater composed of a magnet with an iron core and YBCO coated conductor (CC) tape. A Matlab/Simulink-based simulation model was coupled with a Comsol-based finite element method model to combine the electrical and electromagnetic characteristics to optimize the design configuration of the protection circuit. Experiments with different magnet operating currents and dump resistors were carried out to verify the feasibility of this proposed protection system for magnets with and without an iron core. The results show that the proposed scheme performs within desired specifications and that the dissipation efficiency and velocity vary depending upon different values of the dump resistor.

Cross Layer Design for Video Transmissions in Metro Passenger Information Systems

In metro Passenger Information Systems (PISs), frequent train handoffs can cause severe video distortion. In this paper, we take an integrated design approach to jointly optimize application layer parameters and handoff decisions to improve video transmission quality over PISs. We present a train-ground video communication network based on fountain codes and IEEE 802.11p for metro PISs. The handoff decision and application layer parameters adaptation problem is formulated as a stochastic semi-Markov Decision Process (SMDP). Minimizing the end-to-end total video distortion is the objective in our model. Simulation results show that the proposed SMDP based optimization algorithm can significantly improve the end-to-end video transmission quality in metro PISs.
A new Domain management system for home network

AC Loss Measurement of a Short HTS Cable With Shield by Electrical Method

In order to electrically investigate the AC losses of the conductor and the shield in an actual HTS cable with shield, we attached two voltage-leads to the conductor and shield of a short cable which is the same as the Korea Electric Power Corporation (KEPCO) HTS cable under the field test, and examined it. The result shows that the polarities of the loss voltages measured from both voltage-leads are opposite. The ratio (1.6) between the losses for different transport periods measured from the conductor-lead is quite large. It is considered from these results that the conductor loss is the sum of the losses measured from the conductor-lead and shield-lead. And this conductor loss corresponds well with the numerical result too. Moreover, the total loss of the short cable measured from the proposed electrical method at 77 K was compared with that of the KEPCO cable by calorimetry at 66.6 K through our numerical model. The difference between the measured losses and numerical ones is almost the same. This means that the shield loss is measured from the shield-lead, and the conductor loss from both voltage-leads.
Investigation on High Efficient Catalyst for Catalytic Wet Oxidation Technology

The Catalytic Wet Oxidation (CWO) method was investigated to treat wastewater from chemical container cleaning process, which contains various and high-strength pollutants. A heterogeneous catalyst was studied with Cu2+ as the active component and activated carbon as the supporter. The effects of Cu2+ concentration, calcination temperature and calcination time on the Cu-based catalyst performance were explored and optimal catalyst preparation recipe was optimized as 3h calcination at 300K with 6% Cu2+ impregnation concentration. In addition, Ce doped Cu-based catalyst was also studied, which showed 6% Ce doping was the optimal Ce loading content. The catalysts with and without Ce doping were characterized by thermal analysis (TA) and scanning electron microscopy (SEM) and X-ray diffraction (XRD). Catalyst life and metal leaching were investigated also. The results showed that Ce improved the activity and stability of catalysts. Besides, the amount of leaching Cu2+ was less than 0.15mg/L, and the chemical oxygen demand (COD )removal was increased from 89.7% to 94.8%.
Extraction of Periodic Signal Without External Reference by Time-Domain Average Scanning

A novel signal-analysis technique that is capable of extracting periodic signals from noisy discrete-time observations without an additional external reference is presented. It is based on a derived formulation estimating the maximally allowable synchronous error for a given attenuation threshold after the time-domain averaging. First, a continuous signal is reconstructed from the discrete samples by using cubic-spline interpolation. Second, the region that the signal fundamental frequency may lie in is finely discretized, resulting in a number of candidates of the fundamental-frequency estimate. Third, for each candidate, the continuous signal is synchronously sampled, and the resultant discrete sequence is processed with the time-domain average. Such an operation of repeated sampling and averaging is referred to as scanning. Finally, the obtained series of average waveforms and their amplitude spectra are depicted as two gray images to visualize the computational results, and the waveforms and spectra of interest are picked out for further analysis. Examples are given to confirm the validity of the approach to diagnose machine faults under complicated conditions.
Power-Aware Routing Algorithm Based on Mobile Agents (PARAMA) in Mobile Ad Hoc Networks

Nowadays most ad hoc mobile devices heavily depend on the performance of batteries. Optimizing the power consumption is a very crucial issue. To maximize the lifetime of mobile ad hoc network, the power consumption rate of each node must be evenly distributed. In this paper we present a novel power-aware routing algorithm based on mobile agents to deal with the routing mechanism in the energy-critical environments. A few mobile agents move in the network and communicate with each node. They collect the network information to build the global information matrix of nodes. The routing algorithm chooses a shortest path if all nodes in all possible routes have sufficient battery capacity. When the battery capacity of some nodes cannot meet a predefined threshold, the corresponding routing schema through these nodes will be ignored. Additionally, we compare the performance of different types of power-relation routing algorithms in simulation environment. The results show that the network has better energy consumption balance with the less network traffic and the better load balancing. Furthermore, this approach has better robustness to ensure the survivability of ad hoc network.
Notice of RetractionInvestigation the Concentrations of Serum Hormone among the Male Workers in the Battery Plant

To explore effects of lead exposure on the concentrations of serum hormone in male workers.  Blood sample of 137 male workers occupationally exposed to lead and 140 male worker without exposure history were collected, of which the concentrations of blood lead (PbB) were determined by flame atomic absorption spectrometry, and concentrations of thyroid stimulating hormone (ΓSH), triiodothyronine(T3), thyroxine (T4), luteinizing hormone (LH), follicle stimulating hormone (FSH), testosterone (Γ) were measured using radioimmunity method.  The results showed that concentration of PbB were significantly higher (P<;0.01) compared with non-exposured group when the concentration ofT3 (1.26±0.24)ng/ml,T4(75.22±17.17)ng/ml, T(3.98±1.37)ng/ml, LH(3.17±1.21)mIU/ml in exposure group were significantly lower compared with T3(1.47±0.32)ng/ml, T4(89.92±21.32)ng/ml, T(5.29±1.84)ng/ml, LH(10.18±1.63)mIU/ml (P<;0.05) in non-exposured group. In contrast, thyroid stimulating hormone (TSH) concentration were significantly increased (P<;0.05) than control group. The differences between the FSH was not significantly different from that in non-exposured group.  The results suggest that the lead exposure may not only harm the function of thyroid, which might injure endocrine function, also interfere with the secretion of sex hormone.
Using human body gestures as inputs for gaming via depth analysis

Natural ways of input greatly enhance the entertainment experience for emerging gaming systems represented by the Sony Playstation 2 EyeToy and the Nintendo Wii Console. In this paper we present a novel method of using human body gestures depth image as gaming application input. Depth images have natural advantages over grayscale or color images in terms of robustness against illumination change, texture complexity, and background interference. Our proposed method consists of three major components: depth image acquisition, mean shift based preprocessing, and HMM-based gesture recognition. We validate our method by applying it to a boxing game scenario to distinguish boxing gestures such as dodge, jab, hook, and uppercut. The experiment results indicate that our method can efficiently distinguish the subtle differences among these gestures and yield excellent accuracy (up to about 98%). The potential usage of the proposed method on gaming applications and generic human computer interaction is very promising.
One-step pointer forwarding strategy for location registration in LEO satellite network

LEO satellite communication systems are an important part of the future global personal communication infrastructures. An important aspect of the LEO satellite network is to manage the location of both users and satellites. Many network signal flows and database updates and queries are required to accomplish such a task.

Electrospun Biodegradable Nanofiber Mats for Controlled Release of Herbal Medicine

Biodegradable polymer polycaprolactone (PCL; Mw~100,000) fiber mats containing shikonin from the plant Lithospermum
 erythrorhizon
, widely known for its wound healing, anti-tumor, antioxidant, and anti-inflammatory properties, were prepared via electrospinning method. Incorporation of shikonin in the neat PCL solution did not affect the morphology of the resulting fibers, as both the neat and the shikonin-loaded PCL fibers were smooth. The shikonin release test was followed in PBS solution containing 0.5 vol.% of Tween 80 and 10 vol.% of methanol. The trends of the process of releasing shikonin from the fibers with different drug loadings were similar, and showed a gradual increase in the cumulative release over the 24 h testing period. The obtained results suggested that the use of electrospun fibers as drug carriers could be promising in the future for biomedical applications.
