Authors: Vysloužilová Lucie , Valtera Jan , Pejchar Karel , Beran Jaroslav , Lukáš David
Published: December 2014

The paper is focused on the design of the electrode for needleless coaxial electrospinning. This method allows to produce core/shell nanofibers from the free surface of a polymeric two-layer. The geometry of the designed model of electrode was analyzed using the software Autodesk Simulation Multiphysics. The results of electrostatic field simulation indicate the sharp edges of the electrode as the source of high electric intensity. These sharp edges lead to the loss of the electric energy during the electrospinning process. Based on that, the new cylindrical geometry of the electrode was developed. The results of carried out experiments clearly demonstrate the enhancement of the electrospinning process stability.

Authors: Kravarikova Helena
Published: December 2014

The process of mixing materials is a very complex process. The mixing process is used for homogenisation of substances. Rather than propose a real mixer, you must first construct a mixer for operational purposes experimental solutions. Experimental solutions are most often realized in laboratory conditions. Experimental mixers are made according to the requirements of power mixers, fluid flow, density and viscosity of the mixed fluid. To investigate the mixing process in the Laboratory mixers are made on the basis of the criteria of non-dimensional simplex. For designing operating mixers can also use analytical solutions of technical equipment and the mixing process. It is now possible to implement solutions using FEM numerical simulation of this phenomenon.The homogeneity of the mixed substances, mixer performs rotational movement about the axis of rotation. In most cases, the rotational movement of the stirrer describes the geometrical shape of the mixer. Usually rotation axis Mixer is the axis of symmetry.

Influence of Smelting Technology on Properties of Soft Magnetic Fe-B-Si Alloys
Authors: Konashkov Viktor , Tsepelev Vladimir
Published: December 2014

The quality of metal production can be different even at identical elemental composition and similar heat treatment. The thermo-time smelting regime influences on structure of a metal melt. The structure of a melt influences on process of a hardening and quality of solid alloy. The thermo-time processing of a melt is very relevant at production of nanocristaline materials. The structure of amorphous ribbon is inherited from a melt. The long-lived relaxation processes can be exist in liquid state. They can lasts units or even tens hours. The thermo-time processing allows to receive an equilibrium melt. The properties of an equilibrium melt depend only on an elemental composition and temperature. The development of thermo-time processing is possible on the basis of analysis of different structural-sensing properties of melts. The thermo-time processing is a combination of heating temperatures and temporary ranges. But more often it is possible to determine temperature at which one a melt passes to an equilibrium state practically instantly. Such temperature is named “critical temperature”. The achievement of “critical temperature” is accompanied by anomalies on relations of properties to temperature. The quality of soft magnetic materials received from melt heated up above than “critical temperature” is higher.

Authors: Plotnikova Natalya V. , Losinskaya Anna , Skeeba Vadim Yu. , Nikitenko Ekaterina
Published: December 2014

The possibility of obtaining of surface layers on low-carbon steel 20 by high-energy methods is shown. The features of structure formation in the surface layers after atmospheric electron-beam deposition of iron-graphite powder mixture and high-frequency current treatment are considered. It is shown that coatings with thickness of 2.6 mm and hardness of up to 8000 MPa are formed during atmospheric electron beam deposition. High-frequency current treatment allows to obtain coatings with thickness from 500 to 1600 μm, which hardness reaches 7000 MPa. Hardness increased is due to the formation of hypoeutectic cast iron structure or hypereutectoid steel during high-energy treatment, depending on the processing modes. It is expected that the increase in surface hardness will positively affect the wear resistance of high-carbon coatings.

A New Multiple UAVs Cooperative Search Model Building and Route Planning Method
Authors: Gao Chun Yang , Zhao Zhen Yu
Published: December 2014

In multiple UAVs cooperative search tasks, the traditional environment model was based on squares, which caused the problem of different cost in each UAV’s single step. Therefore, we divide the battlefield by regular hexagons to make the UAVs’ steps more coordinate. At the same time, the cell’s encoding method was improved, which can greatly reduce the computing complexity of the coordinates. Route planning is an important part in cooperative search to decide where to go and how to search. By analyzing the method of route planning with several steps, Model Predictive Control (MPC) was proved to be an easy and effective method. However it became a complex probem to selecte a best route from so big amount of planning routes. Then the method of Discrete Particle Swarm Optimal (DPSO) was proposed to solve this problem. In order to evaluate the value of the route, an evaluate function was designed, containing the reward function of the route, the repulsion function of the no-fly zone and the force function of other UAVs. The reward function was designed based on the targets’ existence probabilities and the areas’ information uncertainty values. Then the no-fly zone was designed based on the artificial potential field method. However, due to each UAV can fly in different height, that is, collision would not happen, so the force function of other UAVs didn’t need concerned. In the end, a simulation experiment with some static targets and a no-fly zone was carried out, in which, a greed method was put forward to be a comparison to MPC. The results showed that the methodology proposed can ensure that the UAVs detected the targets safely and covered as more area as possible.

Image Classification is an important means of image processing, Traditional research of image classification usually based on following assumptions: aiming for the overall classification accuracy, sample of different category has the same importance in data set and all the misclassification brings same cost. Unfortunately, class imbalance and cost sensitive are ubiquitous in classification in real world process, sample size of specific category in data set may much more than others and misclassification cost is sharp distinction between different categories. High dimension of eigenvector caused by diversity content of images and the big complexity gap between distinguish different categories of images are common problems when dealing with image Classification, therefore, one single machine learning algorithms is not sufficient when dealing with complex image classification contains the above characteristics. To cure the above problems, a layered cascade image classifying method based on cost-sensitive and class-imbalance was proposed, a set of cascading learning was build, and the inner patterns of images of specific category was learned in different stages, also, the cost function was introduced, thus, the method can effectively respond to the cost-sensitive and class-imbalance problem of image classifying. Moreover, the structure of this method is flexible as the layer of cascading and the algorithm in every stage can be readjusted based on business requirements of image classifying. The result of application in sensitive image classifying for smart grid indicates that this image classifying based on cost-sensitive layered cascade learning obtains better image classification performance than the existing methods.

As the change detection based on Synthetic Aperture Radar (SAR) images that are difficult and very limited to acquire labeled samples are of low detection rate and high error rate, Thus a progressive transductive SVM algorithm based on original feature space for unsupervised change detection of SAR images is proposed. The pseudo-training set of the difference image is obtained using K-means clustering method without any prior information; Starting from these initial seeds, the progressive transductive SVM performs change detection in the original multitemporal feature space by gradually considering unlabeled patterns in the definition of the decision boundary between changed and unchanged pixels according to a transductive inference algorithm. Using dynamic region labeling rule, the algorithm not only achieves its rules of progressive labeling and dynamic adjusting, but also raises its speed at the same time. Experimental results obtained on different multitemporal SAR images show that, transductive inference algorithm that extract the information of unlabeled patterns improve the SVM classifier accuracy. These results confirm the effectiveness of the proposed approach.

With the high humidity caused by the urban microclimate, the visibility is greatly reduced due to the fog weather as well as the hazy weather formed by the accumulation of pollutant and vapor. In order to evaluate how the fog and haze weather affects outside lighting, a hazy simulation environment is introduced in this paper. An ultrasonic humidifier is used to produce droplets for fog simulation. Haze is simulated by using air blower to blow plant ashes. Transmittance of several different light sources under the simulated fog and haze conditions is shown. The results can be used to study outside lighting.

Multi-Sensor Stockline Tracking within a Blast Furnace
Authors: Wei Ji Dong , Guo Ge
Published: December 2014

The paper presents a synergistic approach for height tracking within a blast furnace (BF). The Frequency Modulated Continuous Wave (FMCW) radar has been employed to measure the height and surface profile of the burden surface. However the radar signal is easily disturbed, by the radar anomalies, during the process of continuous measurement. The data from rotating chute and charging switch provide information on contextual relevance with radar anomalies. An anomaly detection models has been developed to increase the measurement accuracy by utilizing contextual information. The approach has been validated on real BF. The root mean squared (RMS) error in the measured height is reduced by 17% when using the proposed approach compared to the case without it. The results suggest that the proposed approach successfully adapts to changes in the pattern and characteristics of the burden surface.

Published: December 2014

For the multisensor time-invariant system with uncertainties of both the noise variances and parameters, by introducing a fictitious white noise to compensate the uncertain parameters, the uncertain system can be converted into the conservative system with known parameters and uncertain noise variances. Using the minimax robust estimation principle, and the Lyapunov equation approach, a robust weighted measurement fusion Kalman predictor is presented based on the worst-case conservative system with the conservative upper bounds of noise variances. A Monte-Carlo simulation example shows its effectiveness.

Density three dimensional plant canopy structure data has numerous applications in agriculture, but many existing 3D data collection approaches are time-consuming. In this paper, we present a measurement system based on structured-light for plant canopy structure data collection. The structured-light projector projects laser beam reflected by dual-oscillating mirror, arrives to the plant canopy, which is captured by a camera. We propose a new scanning mode, that is, during one exposure time of CCD camera, one mirror keeps moving in high frequency and small angle, while the other one maintains the same position, so that we can get a laser stripe rather than a spot in each image, from which about 100 sub-pixel centers of laser stripe can be extracted. Experiments show that the measurement system can rapid collect three dimensional information of the plant.

The signal of the pull-pressure sensor after conditioning is conversed by the 24bit A/D converter. The signal is operated real-timely with the encoder data, the setting value of the touch screen and the condition of the keys. The results are stored in the SD card. While the results are displayed on the touch screen. The anti-interference capability of the system is improved by the hardware and software anti-interference design. The reason of the measurement results smaller than the theoretical value is analyzed according to the tests results used of the calibration texting machines. Two aspects of the measures have been proposed to improve the measurement accuracy, including improving hardware stiffness and introducing distortion compensation amount.
