In this work, we adopt the use of deep learning method for no-reference image quality assessment. With the development of deep neural networks technology, foundational and deep features of images could be captured without much prior knowledge. So a sparse autoencoder (SAE) was trained to express a 32 × 32 pixels image into a feature vector. Then the original images were cut into serial sub-images...
State estimation is the foundation of energy management system. The innovation graph state estimation has an advantage over traditional state estimation in identifying bad data. We infer the distribution function of innovation difference and set the threshold in certain false drop rate, which provides the theoretical basis for identifying bad data in mathematics. The range of acceptable measuring...
With the progress of science and technology, the digital receiver has been widely used in communication, radar, navigation system, electronic warfare system and enemy identification system. A new design of digital transceiver unit is proposed: A new method of signal synthesis and the use of cascading Invsinc filter and CIC filter in digital down conversion to achieve decimation and deceleration; can...
Nowaday, mobile crowdsensing (MCS) is widely used in mobile devices, and one of the key challenges is how to motivate users to provide sensing services. In this paper, we explore the sensing task allocation in a MCS environment in which requester aims to maximize the valuation of tasks with limited budget. According to the multi-parameter bids of users including sensing costs and available time, we...
Contrast of image plays an important role in image perception quality and is also susceptive to various factors during image acquisition process. However, only a few image quality evaluation algorithms have been focused on the contrast-changed image quality assessment (IQA), and none of these methods belongs to blind IQA algorithms. Therefore, they cannot be applied to the case when the reference...
In this paper, we develop an end-to-end framework for text region proposal generation and text detection in the natural scene, which takes advantage of the efficient training strategies of the neural network. We make some technical changes over the SSD architectures, so that our method can handle the Chinese and English bilingual situation. Experiments show that our method exceeds the state-of-the-art...
A power oscillation damping controller of the multi-terminal direct current (MTDC) system is proposed in this paper. In a MTDC system, due to the interaction between different generators, interarea oscillation has shown great influence on the system stability. To damp the interarea oscillation, a damping controller for MTDC system is proposed in this paper. Firstly, the topology and control strategy...
With the development of electric locomotives in the direction of high speed and heavy load, the problems of negative sequence current and excessive neutral section in traction network have become more serious than before. Thus, a hybrid railway power conditioner (H-RPC) is proposed for co-phase power supply system to solve these problems. In this paper, the topology and compensation principle of the...
With the development of science and technology, computer technology is increasingly updated, and multimedia search technology has been widely used. For music retrieval, textbased retrieval technology can't meet the diversified retrieval needs. Humming retrieval is through matching the input audio and the audio in the database to match the audio. It's a more convenient way to retrieve music. In this...
The current need for large multimodal databases to evaluate automatic biometrics recognition systems has motivated the development of the XJTU multimodal database. The main purpose has been to consider a large scale population, with statistical significance, in a real multimodal procedure, and including several sources of variability that can be found in real environments. The acquisition process,...
This paper proposes an indoor three-dimensional path planning system for the automatic control of robots using a Kinect V2 sensor. In the method, a RGBD SLAM system using Kinect V2 sensor is introduced to identity the environment and obtain the indoor three-dimensional map. At the same time, the rapidly exploring random tree (RRT) is used for a safe and optimal navigation of robot in three-dimensional...
The importance of social networks has drawn the attention of researchers for many years. It is a hot topic in the research line of financial intelligence. Recently, researchers discovered that the network centrality of board members is an important indicator of a company. However, no previous studies focused on the relation of the company size and the centrality of CTO/CIO. Therefore, we presented...
Rapid and random temporal fluctuations in amplitude and phase of signal caused when GNSS signals are propagating through irregularities in electron density of the ionosphere are called amplitude and phase scintillation. Ionospheric scintillation can degrade receiver tracking performance, and in extreme cases, out of lock entirely. The elfect of amplitude scintillation on the signal is similar to that...
The hydrostatic journal bearings are getting popular due to fulfilling the requirements of supporting heavy loads, high stiffness, and precise movement without wear and friction at low speed. The efficiency of hydrostatic bearing to support the load, depends upon the external source of pressure, which is responsible for supplying fluid at a certain pressure. Normally, external source of pressure is...
Vulnerable code reuse in open source software is a serious threat to software security. However, the existing high-efficiency methods for vulnerable code clone detection have a large number of false-negatives when the code is modified, which results in limited application scenarios. In this paper, we present an innovative fingerprint model to describe the vulnerability code and propose VFDETECT, an...
Wireless multimedia sensor networks (WMSNs) require data to be communicated timely and reliably. However, radio transmission errors incurred by wireless channel make it difficult to achieve these qualities simultaneously. To provide good quality of service (QoS) of WMSNs, parameters associated with the WMSNs need to be studied completely and best tradeoff needs to be made. To characterize the delay-reliability...
Over the past three decades, plenty of techniques have been developed to solve cell formation problems. However, most researchers focus on forming cells in a single run or non-incrementally without considering implementation, planning and capital investment issues. This paper proposes a mixed-integer goal programming model to deal with incremental cell formation problem, in which human factor is involved...
MBD technology is capable of integrating all the information of the design and process technology into the product 3D model. But in the MBD mode, the complex product has massive information, and its structure is extremely complicated. Generally, the existing methods for complex product information modeling have some limitations. By considering that, this paper proposed an F-B-S-F-I framework model...
Combined with popular Internet of things and virtual reality technology, this paper has developed a set of intelligent agriculture, intelligent home in one of the intelligent manor sand table demo system. System test shows that the system can effectively simulate a number of intelligent agriculture, intelligent home in the practical scene. In the intelligent agricultural system part of the use of...
In a Wireless Sensor Network (WSN), there are a large number of nodes whose power supply and computational capability are limited. The nodes in a wireless sensor network can be fixed or move randomly. Thus in these networks, to forward a data packet from one node to another needs to use specific strategies with very different characteristics. Accordingly the data forwarding strategy among nodes plays...
