Emotion is closely related to healthy and abnormal mood is the alarm of our body. This paper is concentrated on the objective and accurate emotion classification using EEG signal. We propose emotional patches and combine it with the deep belief network(DBN) to achieve high-precision emotion classification. DBN is able to fit the distribution of the EEG signal and mapping the extracted feature to the...
Train cruising movement simulation module is an important part of high-speed train moving simulation system. According to the actual cruising movement characteristics of high-speed train, it is very important to design high-speed train cruising movement simulation algorithm to improve the calculation accuracy of train moving simulation system. Based on the conditions and the characteristics of high-speed...
Spectral clustering is one of the most effective methods of data mining, in which the adjacency matrix is constructed by using the similarity matrix. In this paper, to extend spectral clustering method for uncertain data clustering, we propose a new spectral clustering method based on JS-divergence. In the proposed method, the JS-divergence is used to construct the adjacency matrix in the spectral...
This study proposes an online foot position compensator (FPC) for improving the robustness of biped walking. The proposed FPC learns foot placement parameters through sensory feedback and preview control theory to re-plan the trajectories of the center of mass (CoM) and gait pattern; the re-plan is based on the online generation of a walking pattern using the policy gradient reinforcement learning...
A low-power radio analog front-end which includes a self-interference (SI) cancellation circuit and a harmonic-rejection power amplifier (HRPA), is proposed to reduce the interaction between a transmitter (TX) and receiver (RX), to enable full-duplex operation. A prototype TSMC device demonstrates more than 30dB SI cancellation over a 4MHz BW and a PA 3rd and 5th harmonic reduction of 30dB and 15dB,...
Electroencephalogram (EEG) signal based emotion recognition, as a challenging pattern recognition task, has attracted more and more attention in recent years and widely used in medical, Affective Computing and other fields. Traditional approaches often lack of the high-level features and the generalization ability is poor, which are difficult to apply to the practical application. In this paper, we...
Mobile sensors deployment over a target area is an important problem for autonomous operations in applications such as surveillance and environmental monitoring. The problem of optimal deployment of heterogeneous anisotropic field sensor network, having different sensing range, is addressed in this paper. A sensor coverage model for a planar field sensor is developed through introducing a performance...
Since the introduction of Electrical Multiple Units (EMUs) to China, traction control technology has become one of the study hotspots. The traction control system of EMUs consists of a traction converter system and a Traction Control Unit (TCU). The traction converter system is composed of a transformer, a four-quadrant pulse rectifier, intermediate DC link, rheostatic chopper, a three phase half...
Verification is a critical step in the Integrated Circuit (IC) design process. In order to verify a design, a set of assertions based on the design, is generated. The design is checked, either using simulation or formal tools, to make sure that the design does not violate any of the generated assertions. If any of the assertions is violated, then a design bug is detected. The quality of the verification...
Congestion control is an indispensable mechanism in the new trend of enhanced Ethernet as a unified fabric for traditional LAN, SAN, and high-performance computing networks. A congestion management framework for Converged Ethernet (CE) networks has been standardized by IEEE 802.1 Qau work group, and QCN is recommended as the congestion control scheme in the standard draft. QCN is heuristically designed...
Memcached is a widely used in-memory caching solution in large-scale searching scenarios. The most pivotal performance metric in Memcached is latency, which is affected by various factors including the workload pattern, the service rate, the unbalanced load distribution and the cache miss ratio. To quantitate the impact of each factor on latency, we establish a theoretical model for the Memcached...
The shuffle transfer pattern is widely adopted in today's cluster computing applications and the completion time of each group of transmissions directly affects application performance. Because of the restriction on the number of concurrent threads and the TCP Incast problem, the randomized data fetching strategy is widely employed in this kind of communication in practice. In this paper, to assess...
Recently, HTTP-based adaptive video streaming has been widely adopted in the Internet. Up to now, HTTP-based adaptive video streaming is standardized as Dynamic Adaptive Streaming over HTTP (DASH), where a client-side video player can dynamically pick the bitrate level according to the perceived network conditions. Actually, not only the available bandwidth is varying, but also the chunk sizes in...
Fingerprint location algorithm is often used in process of indoor location. But the complex environment will cause fluctuations in signal strength and this fluctuation will lead to positioning errors. In order to correct the error we use Gaussian filtering to preprocess the location data and adopt based on voting region decision policy and based on maximum signal strength AP selection policy. SSCM-WKNN...
Automatic Facial Action Unit (AU) detection has drawn more and more attention over the past years due to its significance to facial expression analysis. Frontal-view AU detection has been extensively evaluated, but cross-pose AU detection is a less-touched problem due to the scarcity of the related dataset. The challenge of Facial Expression Recognition and Analysis (FERA2017) just released a large-scale...
We demonstrate a polymeric electro-optic (EO) modulator with a Mach-Zehnder interferometer (MZI) structure. Low loss fluorinated polyimide (FPI) and low cost nonlinear optical (NLO) chromophores of disperse red 1 (DR 1) were introduced to form the core layer of the modulator. The fabricated EO polymer waveguide exhibits a low propagation loss of 1.14 dB/cm, and the modulating device exhibits a good...
The achievable degree of freedom (DoF) boosting has been demonstrated on a single-input single-output (SISO) X channel by using outdated and instantaneous channel state information at transmitter (CSIT) synergistically, in contrast to that of using completely outdated CSIT. However, the means by which the DoF gain can be obtained in a multiple-input multiple-output (MIMO) system remains unclear. This...
Full-duplex (FD) radio communication potentially doubles the spectral efficiency in the densely occupied RF spectrum (100MHz to 5GHz). However, significant challenges remain, particularly the presence of a strong transmitter (TX) self-interference (SI) coupling to the receiver (RX). Numerous recent efforts on mitigating SI have focused on using active cancellation techniques [1–5]. However, these...
Considering the industrial field, the problems of limited energy and changed topology of the network restrict the development of the centralized resource allocation. Although the traditional distributed resource allocation algorithm solves the network topology change partly, there is still no breakthrough in terms of energy consumption. In this paper, we simulate the Distributed Randomized TDMA scheduling...
Overload detecting mechanisms are the prerequisites for admission controls and differentiated services. Conventional mechanisms are always coordinated with conventional network stacks. As the hardware evolution and applications' increasing demand, the architecture of conventional network stacks make themselves become the bottleneck. In this context, high performance network I/O frameworks have been...
