The interoperability testing of CTCS-3 Level Train Control System guarantees the safe operation of train running on different lines. It makes great sense to achieve automatic analysis of interoperability testing results, which could improve the efficiency and accuracy of testing. In this paper, a research was conducted on automatic analysis of testing results for on-board equipment of train control...
Convolutional neural network (CNN) based face detectors are inefficient in handling faces of diverse scales. They rely on either fitting a large single model to faces across a large scale range or multi-scale testing. Both are computationally expensive. We propose Scale-aware Face Detection (SAFD) to handle scale explicitly using CNN, and achieve better performance with less computation cost. Prior...
Elderly care is one of the important issues in the medical mature of the time facing all over the world. Currently, the paper-based testing and recording methods are commonly used in various care centers which not only waste manpower but also may cause mistakes with different social workers in assessment. This study aims at measuring the cognitive function of elderly by the empirical research approach...
Voice-coil motor has a lot of advantages such as small volume and light weight, high speed, high acceleration and rapid response, hence it is used to drive wafer and reticle stages of lithography machine to accomplish precise motion. The influence of internal cooling on motor's motion accuracy is directly related to the performance and reliability of lithography machine. This paper aims to provide...
The purpose of this study was to explore the effect of three common sports surfaces on plantar pressure characteristics and performance of impact in lower extremity during jogging. Methods: Medilogic insole plantar pressure system® was utilized to collect plantar pressure data (including contact time, peak pressure, pressure-time integral) and pressure distribution during touch-down and toe-off phases...
Although methods for target maneuver onset detection (MOD) abound, few have been proposed for target maneuver termination detection (MTD), since MOD is easier and considered more important. Without MTD, however, decision based maneuvering target tracking is not complete and may suffer from performance degradation and computational waste. This paper proposes sequential testing methods for MTD in the...
The characteristics and behavior of Wald's sequential probability ratio test are revealed by two important functions — operating characteristic (OC) and average sample number (ASN). These two functions have been studied extensively under the assumption of independent and identically distributed (i.i.d.) log-likelihood ratios, which is too stringent for many applications. This paper relaxes the requirement...
According to the consistency of comparison samples in proficiency testing, stability testings were carried out for 3 kinds of lubricating oil specimens which were homogeneous. Based on the precision of oil emission spectrometer, the precision indices of these 3 kinds of lubricating oil specimens were obtained by analyzing the results of the preside laboratory test for the first time, then the data...
A suit of wood-based composite nondestructive virtual instrument system based on Labview was designed in this paper. The sample of poplar Laminated Veneer Lumber was used to discuss the feasibility of the applications of virtual instrument in the wood-based composite nondestructive test. The main results are as follows: the longitudinal resonance elasticity modulus that was measured by virtual instrument...
The high accuracy accelerometer can be demarcated in multiposition tumbling experiment under 1g gravitational field. The g2 observation model of Two Orthometric Accelerometers can eliminate the corner error. there is a serious multicollinearity exit in this system because some model coefficient mix together. In view of above question, this article has given the arithmetic of Empirical Bayes Estimation(EB),...
This study focuses on phenolic-resin/carbon-fiber (PR/CF) ablation composites modified with polyhedral oligomeric silsesquioxane (POSS) and tetraethoxysilicate (TEOS). Four nanomodifiers based on diglycidyl ether of biphenol A (DGEBA), TEOS-SiO2 (T-SiO2), octamethyl-POSS (Me-POSS) and phenyl-POSS (Ph-POSS) were prepared and employed to modify the PR/CF ablation materials. To compare ablation properties...
We introduce a social network analysis method as a new approach to build an Intrusion Detection System (SN-IDS) in ad hoc networks. The SN-IDS utilizes social relations as metrics-of-interest for anomaly detections, which is different from most traditional IDS approaches. To construct proper social networks, we first investigate ad hoc MAC and network layer data attributes and select relevant social...
Adaptive random testing (ART) techniques have been proposed in the literature to improve the effectiveness of random testing (RT) by evenly distributing test cases over the input space. Simulations and mutation analyses of various ART techniques have demonstrated their improvements on fault detecting ability when measured by the number of test cases required to detect the first fault. In this paper,...
