In the problems of image retrieval and annotation, complete textual tag lists of images play critical roles. However, in real-world applications, the image tags are usually incomplete, thus it is important to learn the complete tags for images. In this paper, we study the problem of image tag complete and proposed a novel method for this problem based on a popular image representation method, convolutional neural network (CNN). The method estimates the complete tags from the convolutional filtering outputs of images based on a linear predictor. The CNN parameters, linear predictor, and the complete tags are learned jointly by our method. We build a minimization problem to encourage the consistency between the complete tags and the available incomplete tags, reduce the estimation error, and reduce the model complexity. An iterative algorithm is developed to solve the minimization problem. Experiments over benchmark image data sets show its effectiveness. Copyright © 2017, The Authors. All rights reserved.

Human saccade is a dynamic process of information pursuit. There are many methods using either global context or local context cues to model human saccadic scan-paths. In contrast to them, this paper introduces a model for gaze movement control using both global and local cues. To test the performance of this model, an experiment is done to collect human eye movement data by using an SMI iVIEW X Hi-Speed eye tracker with a sampling rate of 1250 Hz. The experiment used a two-by-four mixed design with the location of the targets and the four initial positions. We compare the saccadic scan-paths generated by the proposed model against human eye movement data on a face benchmark dataset. Experimental results demonstrate that the simulated scan-paths by the proposed model are similar to human saccades in term of the fixation order, Hausdorff distance, and prediction accuracy for both static fixation locations and dynamic scan-paths.

Comparison of CFd-calculations of centrifugal compressor stages by NUMECA Fine Turbo and ANSYS CFX programs

IOP Conference Series: Materials Science and Engineering 2017年第1期232卷

作者： Y B Galerkin I B Voinov A A drozdov R&D Laboratory 'Gas dynamics of turbo machines' Peter the Great St. Petersburg Polytechnic University Polytechnical st. 29 St. Petersburg Russia Engineering Center 'Center of Computer-Aided Engineering' Peter the Great St. Petersburg Polytechnic University Polytechnical st. 29 St. Petersburg Russia

Computational Fluid dynamics (CFd) methods are widely used for centrifugal compressors design and flow analysis. The calculation results are dependent on the chosen software, turbulence models and solver settings. Two of the most widely applicable programs are NUMECA Fine Turbo and ANSYS CFX. The objects of the study were two different stages. CFd-calculations were made for a single blade channel and for full 360-degree flow paths. Stage 1 with 3d impeller and vaneless diffuser was tested experimentally. Its flow coefficient is 0.08 and loading factor is 0.74. For stage 1 calculations were performed with different grid quality, a different number of cells and different models of turbulence. The best results have demonstrated the Spalart-Allmaras model and mesh with 1.854 million cells. Stage 2 with return channel, vaneless diffuser and 3d impeller with flow coefficient 0.15 and loading factor 0.5 was designed by the known Universal Modeling Method. Its performances were calculated by the well identified Math model. Stage 2 performances by CFd calculations shift to higher flow rate in comparison with design performances. The same result was obtained for stage 1 in comparison with measured performances. Calculated loading factor is higher in both cases for a single blade channel. Loading factor performance calculated for full flow path ('360 degrees') by ANSYS CFX is in satisfactory agreement with the stage 2 design performance. Maximum efficiency is predicted accurately by the ANSYS CFX '360 degrees' calculation. 'Sector' calculation is less accurate. Further research is needed to solve the problem of performances mismatch.

Modeling and Simulation methods, tools and techniques aim at supporting the different phases of the lifecycle of modern systems, going from requirements analysis to system design and operation. However, their effective application requires investigating several aspects such as the formal modeling of system requirements and the binding and automated composition between heterogeneous models (e.g. requirements models, architectural models, behavioral models). In this context, the paper presents a new formal requirement modeling language based on temporal logic, called FOrM-L, and a software library, based on the Modelica language, that implements the constructs provided by FOrM-L so as to enable the visual modeling of system properties as well as their verification through simulation. The effectiveness of the proposal is shown on a real case study concerning an Intermediate Cooling system.

A bidirectional dC-dC converter is employed to control the power of the secondary storage element according to the references set by the energy management system in a semi-active hybrid topology for an urban electric vehicle. This study proposes an improved dC-dC converter to connect supercapacitors to the main dC bus. The dC-dC converter controller is oriented by references provided by an online management algorithm. The feeding system model including its inner control layer is addressed to introduce the energy strategy system, considering an improved three-level dC-dC converter. decisions at the energy management strategy level are supported by a fast meta-heuristic approach. Simulations using Matlab-Simulink are provided to demonstrate the performance of the selected topology in order to keep the batteries and supercapacitors within physical limits on the driving cycle.

Channel measurements and path-loss modelling for typical indoor environmentsat 28-GHz band, in both line-of-sight and non-line-of-sight scenarios, are conducted. An automatic measurement system is designed and used, with multiple combinations of steerable transmit and receive antennas at both azimuth and elevation planes. Based on the measured data, the received signal is combined in plural, in azimuth and elevation plane, at both transmit and receive sides. Therefore the influence caused by the radiation pattern could be offset. Then, the pathloss is modeled as the product of a distance dependent term, and the standard deviation of shadow is also discussed.

KAGrA is a newly built gravitational wave observatory, a laser interferometer with a 3 km arm length, located in Kamioka, Gifu prefecture, Japan. In this article, we describe the KAGrA data management system, i.e., recording of data, transfer from the KAGrA experiment site to computing resources, as well as data distribution to tier sites, including international sites in Taiwan and Korea. The amount of KAGrA data exceeded 1.0 PiB and increased by about 1.5 TB per day during operation in 2020. Our system has succeeded in data management, and has achieved performance that can withstand observations after 2023, that is, a transfer rate of 20 MB s-1or more and file storage of sufficient capacity for petabyte class. We also discuss the sharing of data between the global gravitational-wave detector network with other experiments, namely LIGO and Virgo. The latency, which consists of calculation of calibrated strain data and transfer time within the global network, is very important from the view of multi-messenger astronomy using gravitational waves. real-time calbrated data delivered from the KAGrA detector site and other detectors to our computing system arrive with about 4–15 seconds of latency. These latencies are sufficiently short compared to the time taken for gravitational wave event search computations. We also established a high-latency exchange of offline calibrated data that was aggregated with a better accuracy compared with real-time data.

The study is carried out in the framework of cooperation between IEE-CAS and EdF r&d since 2012 on the Badaling 1MWe concentrated solar tower power plant located in the suburb of Beijing. The paper first presents a dynamic model of the power plant, in which Modelica library ‘ThermoSysPro’ was applied under the simulation environment dymola ® . The model comprises sun to power generation loop and thermal storage system including two tanks oil and a steam accumulator. A detailed shell and tube steam-oil sectional heat exchanger has been modeled and implemented to simulate the heat transfer performance. By doing this, storage charging and releasing procedure could be predicted delivering transient behaviors of the upstream and downstream steam quality. A two-level control design on the Matlab/Simulink ® was developed and tested on the detailed dymola ® model. For realizing the coupling of two simulation tools, different approaches, were attempted, among which OPC server structure is suggested and presented in detail in this paper.
