Based on the characteristics of short pulse signals in the marine animals sound and the characteristics of the high temporal resolution of the wavelet transform, this paper proposed a new strategy of Constant False Alarm Rate(CFAR) pulse detection based on continuous wavelet transform(CWT). The CFAR pulse detection was carried out on each scale of the results of time frequency analysis of CWT. Then...
Despite the recent success of deep-learning based semantic segmentation, deploying a pre-trained road scene segmenter to a city whose images are not presented in the training set would not achieve satisfactory performance due to dataset biases. Instead of collecting a large number of annotated images of each city of interest to train or refine the segmenter, we propose an unsupervised learning approach...
Permanent magnet synchronous motor with its high torque density, high efficiency and high reliability, has become the mainstream of the drive system for electric vehicles, elevators, etc. The existing method of fault diagnosis based on the motor model has not considered the fractional characteristics of motor. it is difficult to effectively diagnose minor faults of the current. With the permanent...
This paper presents a novel deep regression network to extract geometric information from Light Field (LF) data. Our network builds upon u-shaped network architectures. Those networks involve two symmetric parts, an encoding and a decoding part. In the first part the network encodes relevant information from the given input into a set of high-level feature maps. In the second part the generated feature...
A biped robot should be able to keep balance under unexpected disturbance, and can take up to four strategies, i.e. ankle, hip, step and reach & grasp strategies to recover balance. In this paper, the relationship between feet-ground constraints, namely the gravity constraints, the friction constraints and the Center of Pressure ( CoP ) constraints, and balance recovery strategy are analyzed....
This article presents a novel internal pattern-switchable high-gain antenna array design for satellite mobile phone applications. By designing two sets of two-element 1.0 wavelength folded loop antenna array at top and side edge of a handset ground respectively, four different directional and steerable fan-shape radiating beams can be formed successfully to cover the 360 degree parallel with and surrounding...
The efficiency of inter-domain routing in large-scale mobile network environments is a critical issue, as traditional prefixed addresses may fail due to the dynamic topologies of mobile networks, where devices would be required to maintain massive routing tables. To address this issue, in this paper we leverage the principles of probabilistic data structures in the inter-domain routing scheme, and...
In our previous works (Liu & Su, 2016a [1], 2016b [2]), we had studied the scheduling of medical resource order and distribution based on an influenza diffusion model. In paper [1], the order size in distribution centers (DCs) was set to be a constant number, and it was improved to be a decision variable in paper [2]. A core decision variable, the number of beds assigned for epidemic patients...
This paper presents a novel carbon emission flow (CEF) model to assess and analyze the carbon emission of each component in power networks. Through the use of information about CEF, demand side management (DSM) and supply side management (SSM) are combined to reduce the emission. Three levels of load curtailment and three strategies of renewable energy sources (RES) utilization are proposed. The IEEE...
Recent embedded ReRAM has a small resistance-ratio (R-ratio), which results in a small read sensing margin (ISM). A larger BL current (IBL) increases the input offset (IOS) of current-mode sense amplifiers (CSA), resulting in low-yield read operations and long read access times (TCD). This work proposes an IBL-aware small-IOS CSA, using a dynamic trip-point-mismatch sampling (DTPMS) scheme to increase...
Interference management is a fundamental problem for the device-to-device (D2D) network, in which transmitter and receiver pairs may be arbitrarily located geographically with full frequency reuse, so active links may severely interfere with each other. This paper devises a new optimization strategy called FPLinQ that coordinates link scheduling decisions together with power control among the interfering...
The traditional drawing robot applications mostly need lots of manpower to select plotting points and determine the drawing process, which would took a long time and hard to design. To solve this problem, this paper proposes a drawing robot system, which can draw a picture what user wanted. There are two main parts in the drawing robot system. One is the delta robot manipulator that includes inverse...
This paper studies a single-cell uplink massive device communication scenario in which a large number of single-antenna devices are connected to the base station (BS), but user traffic is sporadic so that at a given coherence interval, only a subset of users are active. For such a system, active user detection and channel estimation are key issues. To accommodate many simultaneously active users,...
In this paper, Haar-like patterns and a classification machine were employed for fingerprint feature extraction. Although the Gabor filter has high accuracy for feature extraction under a wide angle representation range, the full range of the filter is not required. Moreover, fingerprints have clear direction field representation. Due to these two key factors, this paper uses modified Haar-like patterns...
We report on the implementation of a path planning algorithm on the TrueNorth neurosynaptic system. Our implementation exploits processing in the temporal domain within the architectural constraints of the TrueNorth chip to deduce the optimal path. The optimal path is computed on the TrueNorth chip for grid maps with dimensions as large as 173 χ 168 nodes consuming 70.0mW at an operating voltage of...
In this paper, we introduce a computer vision-based attack using stereo cameras against authentication approaches for touch-enabled devices. In the attack, an attacker uses a stereo camera (such as one on the HTC Evo 3D smartphone) and takes a video of a victim entering passwords on the touch screen of the victim's mobile device. We focus on challenging scenarios where the victim holds the device...
This paper proposes a strategy for navigating a group of mobile robots through an unknown environment con- taining various obstacles. Each robot is equipped with infrared sensors for obstacle detection. The group has one leader robot and several follower robots. The followers follow the leader and maintain a certain distance from one another, enabling them to form a regular polygon around the leader...
A cooperative strategy for a multirobot system designed to seek multiple sources is proposed in this paper. In the strategy, mobile robots are divided into several groups that simultaneously search different regions. During regional exploration, the robots collect environmental information and share it with one another. This cooperative strategy enables multiple signal sources to be detected more...
This paper discusses the role of academia in contributing to the advanced process control of industrial processes. We first review the current maturity of process control in different process industries.

Current process industries such as refineries and pharmaceutical industries have been facing increasing challenges with respect to productivity, reducing waste and energy consumption, as well as environmental and safety issues becomingly increasingly comprehensive. One way to address these issues is to utilize online dynamic simulation via process modelling and control software. While there are multiple...
