Mutation Based Fault Localization(MBFL) is a fault localization technique based on mutation analysis, which precisely identifies the location of fault but incurs a high execution cost, since it needs to execute the test suite on a large amount of mutants. Reduction strategies proposed are usually regarding selecting mutation operators or sampling mutants directly, meanwhile at the cost of losing precision...
Aimed at the study of multi-degree-of-freedom bionic eye drive problem, this paper puts forward a novel hybrid drive multi-degrees-of-freedom permanent magnet motor with liquid suspended bearing. The structure and working principle of the motor is introduced. The rotor's magnetic field of the air gap in this permanent magnet motor is analyzed using both the finite element method and analytical method...
This paper presents a new type of 3-DOF type combined drive motor, which can realize the rotation and deflection movement. The original type of 3-DOF type combined drive motor in the comparison between the basic structures is given with the working principle, etc. The air-gap magnetic field of the motor is calculated and the analysis is carried out under the spherical coordinates of the scalar magnetic...
Objective - Minimally invasive surgery has been widely embraced due to its multitude benefits, especially less traumatic. The key to its success is the instruments' accessibility and manipulability inside the confined surgical space. This motivates researchers to develop flexible manipulators, which could bend inside the body cavity. Two representative flexible manipulators include the wire-driven...
Clinical data describing a patient's health status can be multi-labelled. For example, a clinical record describing patient suffering from cough and fever should be tagged with both two disease labels. These co-occurred labels often have interrelation which can be exploited to improve disease classifications. In this work, we treat the categorization of free clinical text as a multi-label learning...
For the Steer-by-Wire system, it is necessary to develop advanced control systems and to design advanced architectures. In this paper, a new SBW control system with the consideration of the variable gear-ratio is presented. This SBW system includes two control loops, which are called upper control loop and lower control loop, respectively, to achieve bilateral control. The force feedback motor, which...
Given the diversity of commercial Cloud services, performance evaluations of candidate services would be crucial and beneficial for both service customers (e.g. cost-benefit analysis) and providers (e.g. direction of service improvement). Before an evaluation implementation, the selection of suitable factors (also called parameters or variables) plays a prerequisite role in designing evaluation experiments...
Feature selection has been a key technique in massive data processing, e.g. microarray data analysis with few samples but high dimensions. One common problem in multi-class data analysis is the unbalanced recognition accuracies among classes, which leads to poor system performance. One main reason is that most feature selection methods focus on the performance of whole dataset while pay little attention...
This paper constructs a new formal context called n-Strong-Direct-Product formal context (n-SDPFC, for short) by the strong direct product of n formal contexts, and then discusses the connection between the n-SDPFC and the n original contexts from four aspects: concept lattice, implications between attributes, irreducible elements and attribute characteristics. It is proved that the projection of...
An integrating fast readout detector is being developed for the X-ray Pump Probe (XPP) instrument at the Linac Coherent Light Source (LCLS). The detector is based on X-ray Active Matrix Pixel Sensors (XAMPS) with their dedicated readout ASICs. It covers a dynamic range of more than 10,000 photons of 8 keV energy with a resolution better than half photon FWHM. The frame of 1024 ?? 1024 pixels will...
This thesis presented a framework of the possible combination of approaches for low-level program slicing-based-dependence analysis and high-level concept assignment. Three combination techniques, concept extension, concept abbreviation and concept refinement, are presented and empirical studied to address the problem of program maintenance. The ten C subject programs are studied and more than 600...
In this paper, we consider the problem of robust facial expression recognition and propose a novel scheme for facial expression recognition under facial occlusion. There are two main contributions in this work. Firstly, a novel method for facial occlusion detection based on robust principal component analysis (RPCA) and saliency detection performs efficiently to detect facial occlusions. Secondly,...
Aspect composition in the aspect-oriented software may lead to the structural conflict and behavioral conflict, which are two key issues must be solved in the trusted aspect-oriented software development. The paper introduces an approach to solve the problems of the structural conflict in the architecture level, based on the reflection mechanism, and brings forward an approach based on the concepts...
