Fixed polarity Reed-Muller expressions (FPRMs) are well-suited for many practical applications due to they have many excellent properties. In order to obtain an optimal FPRM with fewest product terms, we propose an efficient minimization algorithm (EMA-FPRMs) for FPRMs. The main idea behind the EMA-FPRMs is that, firstly, the incompletely specified Boolean function is transformed into the zero polarity...
Many image processing algorithms have been parallelized successfully on many-core processors, such as GPU and Intel Xeon Phi. In this paper, we choose the Sunway many-core processor SW26010, which is a new processor designed and made in China that constitutes the current NO.1 supercomputer Sunway TaihuLight. This paper firstly introduces the architecture of Sunway SW26010 processor and two representative...
The development of cloud computing is surely unprecedented in IT industry with many companies adapting to this new technology. The related companies undoubtedly benefit a lot from cloud computing. Meanwhile, the security of cloud platforms becomes one of the concerns for companies. As an important underlying component, the virtual machine image is also in need of especial protection. In this paper,...
In the cloud computing environment, one of the most important module is the Scheduler. As the most popular open-source cloud platform, OpenStack provides us with a massive amount of scheduling strategies. But there is no one considering of the hierarchies of the VMs and hosts. We will guarantee the security of VM through these hierarchies. Although OpenStack is abundant in scheduling strategies, none...
Accurate prosodic phrase prediction can improve the naturalness of speech synthesis. Predicting the prosodic phrase can be regarded as a sequence labeling problem and the Conditional Random Field (CRF) is typically used to solve it. Mongolian is an agglutinative language, in which massive words can be formed by concatenating these stems and suffixes. This character makes it difficult to build a Mongolian...
Chinese word segmentation plays an important role in Chinese text mining. It is the foundation of automatic relation extraction and identification in Chinese information processing. In this paper, we propose a method for Chinese word segmentation based on conditional random fields (CRF) with character clustering. For the character clustering, we firstly use the Skip-Gram model to obtain character...
Transfer learning aims to extract the knowledge from a label-rich source domain to enhance the predictive model of a target domain. Previous methods achieve knowledge transfer by detecting a shared low-dimensional feature representation from source domain to target domain. Along this line, many algorithms, e.g., dual transfer learning (DTL), triplex transfer learning (TRi-TL) etc., have been proposed...
With the rapid development of online social media, the short text has become the prevalent format for information of Internet. Due to the severe data sparsity issue, accurately discovering knowledge behind these short texts remains a critical challenge. Since regular topic models, such as the Latent Dirichlet Allocation (LDA), can not perform well on short texts, many efforts have been put on building...
In this study, softwood pulps with Schopper Riegler (SR) freeness of 10 °SR, 17 °SR, 31 °SR, 40 °SR, 48 °SR were used to prepare presspaper samples. Morphological properties of fibers and presspaper were characterized by optical microscope (OM) and scanning electron microscope (SEM). Mechanical and electrical performances of obtained samples were evaluated. Results show that cellulose fibers become...
With the rise of cloud computing, resource scheduling in cloud computing platform has gained more and more attention. OpenStack, as one of the most popular open source cloud computing platform, has done a lot of work for physical resources scheduling. As is known to all, users of OpenStack need to allocate resources when the VM was created. So the process of resource allocation plays an important...
Due to their high resolution and positioning accuracy, piezo-nanoposititioning stages are widely used in precision and ultra-precision fields. A nano-positioning platform with large travel range and bidirectional symmetrical output characteristic is proposed. Theoretical static model develops the relationships among output force, displacement, static stiffness and the structure parameters of the platform...
Massive multi-input multi-output (MIMO) can provide high throughput improvements by using a large number of antennas to serve a small number of terminals simultaneously. Due to channel hardening of massive MIMO, this paper directly investigates the approximate network throughput with zero-forcing beamforming (ZFBF) and conjugate beamforming (CBF) schemes when channel state information (CSI) acquisition...
The channel model of propagation characteristics is significant in the study of three-dimensional multiple-input multiple-output (3D-MIMO) technique. In reality, the materials of buildings affect the parameters of the channel model in terms of reflection and diffraction. In this paper, signal propagation is studied in the 2.4 GHz band based on ray-tracing method in two empty rooms, one with wood walls...
In networked multiagent societies, how global social order (i.e., social norm) can be achieved through agents' local interactions is a critical research problem in multiagent systems. It has been shown that learning from individual local interactions is an effective mechanism to facilitate norm emergence. Most of the existing work, however, mainly focuses on studying norm emergence via agent learning...
This study explores the possibility of enhancing both mechanical and breakdown properties of insulating presspaper by introduction of an organic nano additive. Two different concentrations of nanofibrillated cellulose (NFC) were taken into account, namely 0.5 wt. % and 10 wt. %. Presspaper containing no NFC was also prepared as a reference. Obtained samples were characterized by scanning electron...
Full-duplex (FD) communication can be applied to the cellular network to improve the spectral efficiency, which has been recently proved feasible because of the advanced self-interference cancellation techniques. In FD communication enabled cellular networks, how to effectively pair a downlink user and an uplink user to transmit on the same wireless channel is a critical and challenging issue. To...
Information of the power distribution network engineering is a very important part during whole life period management process of the engineering. When every participant party can obtain and use their demanded in-formation conveniently, swiftly and accurately in every stage during the whole life period management process, it can realize maximization of production efficiency of labor property and material...

The present contribution concerns the activities carried out in the Clean Sky GRC5 MANOEUVRES project. The overall goal of the project is to provide an innovative system to monitor rotorcraft noise in flight, in view of performing optimized low-noise terminal procedures. To achieve this goal it is necessary to estimate in real time the main rotor tip-path plane (TPP) orientation with respect to the...
This paper proposes a novel adaptive feedforward control strategy based on the parameters identification of a permanent magnent linear synchronous motor (PMLSM). The parameters such as the moving mass and viscous coefficient of a PMLSM are identified through an unbiased least square estimation approach with the employment of current and position signals from the built-in sensors. Based on the identified...
