A new coil optimization procedure is proposed for inductively coupled wireless power transfer when square single-turn printed coils are used, by means of analytically modeling the self- and mutual-inductances, parasitic resistances, and parasitic capacitances of these coils. As an example, the average diameter and trace width of the transmitting coil and the trace width of the receiving coil are optimized...
As part of the PhysioNet / Computing in Cardiology Challenge 2016, this work focuses on automatic classification of normal / abnormal phonocardiogram (PCG) recording, with the aim of quickly identifying subjects that need further expert diagnosis. To improve the robustness of the classifiers by increasing the number of training samples, the recordings were windowed into 5 second segments and our classifiers...
This paper describes a novel system for recovering power and providing full-duplex communication over an AC-coupled 4-wire lead between active implantable devices. The target application requires a single Chest Device be connected to a Brain Implant consisting of multiple identical optrodes that record neural activity and provide closed loop optical stimulation. The interface is integrated within...
Since social media have become very popular during the past few years, researchers have been focusing on being able to automatically process and extract sentiments information from large volume of social media data. This paper contributes to the topic, by focusing on sentiment analysis for Chinese social media. In this paper, we propose to rely on Part of Speech (POS) tags in order to extract unigrams...
Hadoop is a widely adopted open source implementation of MapReduce. A Hadoop cluster can be fully provisioned by a Cloud service provider to provide elasticity in computational resource allocation. Understanding the performance characteristics of a Hadoop job can help achieve an optimal balance between resource usage (cost) and job latency on a cloud-based cluster. This paper presents a method that...
A multi-pixel photon counter was characterized by the quantum detector tomography and demonstrated to be a fundamental quantum detector for the observation of non-classical phenomenon according to the negative values of the Wigner function.
Due to resolving the key escrow problem and public key authentication problem, certificateless public key cryptography has drawn many attentions from numerous scholars and experts in recent years and becomes a hotspot for cryptography research. Most recently, the scholars of He and Du proposed a forward secure certificateless proxy blind signature scheme. Through the security analysis on the forward...
With the wide application of cloud computing, cloud computing security issues are now becoming more and more popular. By analyzing the security of information resources sharing in cloud computing environment, this paper discusses the technical, political and social issues of security protection.
Accurate analysis of mooring system is one of the key issues in exploitation of platforms for deep water. In this paper, the depth of analysis about this combination mooring system is illustrated base on mechanical analysis and geometry, the consequences are obtained by MATLAB mathematical software, and then develop the mooring system analysis model. Focusing on the analysis of the critical situation...
Implementing trajectory data stream analysis in parallel has technical issues of data partition and improvements of the analysis operations. In this paper, we define the trajectory analysis problem as discovering trajectory companies of moving objects. We develop a discovery workflow in parallel batch processing. We solve technical issues of data partition and data locality in the steps of analysis...
The advances in location-acquisition technologies have generated massive spatio-temporal trajectory data, which represent the mobility of a diversity of moving objects over time, such as people, vehicles, and animals. Discovery of traveling companions on trajectory data has many real-world applications. Most of existing discovery approaches are limited to centralized computing, while these techniques...
Objective: Exploring the regular pattern in combination characteristics of tongue, complexion and pulse in Traditional Chinese Medicine (TCM) and further discussing the standardization of syndrome differentiation of Chronic Gastritis. Methods: Based on 919 Chronic Gastritis cases collected, we combined the algorithms of SM spectral clustering with modularity to identifying sign groups for the involved...
Recent studies have demonstrated that a well designed deep convolutional neural network (CNN) model achieves competitive performances on detecting the presence of secret message in digital images, compared with the classical rich model based steganalysis. In this paper, we propose to investigate a category of very deep CNN model–the deep residual network (DRN), for steganalysis. DRN is suitable for...
In some occasions like the coal volume statistics in coal mines, the steel volume statistics in steel mills and so on, rapid measurement is required in real-time volume statistics. This paper proposed a dynamic volume measurement system based on the line structured light vision sensor. First, we accurately extract the light strip center with the Steger algorithm, and the camera intrinsic parameters...
A ball grid array (BGA) is a type of surface-mount package used for integrated circuits. In more advanced technologies, solder balls may be used on both the PCB and the package. Also, in stacked multi-chip modules, solder balls are used to connect two packages. The process steps prior to the final BGA ball mount process are becoming increasingly complex, which will induce BGA pad surface oxidation...
Anti-drift is an emergent and challenging issue in data-related subjects. In this paper, we propose to address the time-varying drift (e.g. electronic nose drift). By viewing drift to be with different probability distribution from the regular data, a robust subspace projection approach with PCA synthesis is proposed for anti-drift. The main idea behind is that given two clusters of data points with...
The objectives of this paper were to examine cultivar differences of aboveground rice plant morphology and structure at the early tillering stage, and analyze its potential correlations with yield. The 4 rice cultivars, Liangyou108 (hybrid long-grain rice, V1), 86You8 (hybrid round-grain rice, V2), Nanjing43 (round-grain rice, V3), and Yangtao6 (long-grain rice, V4), were grown in field. Their rice...
The details of oriented visual stimuli are better resolved when they are horizontal or vertical rather than oblique. This "oblique effect" has been researched and confirmed in numerous research studies, including behavioral studies and neurophysiological and neuroimaging findings. Although the "oblique effect" has influence in many fields, little research integrated it into computational...
To quantify the relationships between rapeseed stem and rachis geometric parameters and the corresponding organ biomass, we presents a biomass-based model of stem and rachis geometric parameters of rapeseed (Brassica napus L.), including biomass-based total length model for ramification, maximum diameter model for ramification, length model for main stem, maximum diameter model for main stem, and...
In this chapter, we introduce the pointwise approach to learning to rank. Specifically, we will cover the regression-based algorithms, classification-based algorithms, and ordinal regression-based algorithms, and then make discussions on their advantages and disadvantages.
