Research on code clone evolution is very hot, and it can contribute to the investigation of the characteristics, the maintenance, the refactoring, and the harmfulness evaluation of code clones. In clone evolution research, extracting clone genealogies is the key technique, and mapping clone groups between neighboring software versions is a thorny issue for extracting clone genealogies. The efficiency...
This paper develops a Stackelberg game model within a supply chain with one manufacturer and one retailer under the government incentive system, where the remanufacturing products are undifferentiated with the new ones. This paper is different from most of the extant literature about remanufacturing because they consider the effect of structure and recovery strategy on the system efficiency rather...
In this paper, we present a Support Vector Regression (SVR) system to measure the semantic similarity of short texts by combining multiple similarity measurements, i.e., string similarity, knowledge-based similarity, corpus-based similarity, syntactic dependency similarity, number similarity and machine translation similarity. Experiments on the five data sets of SemEval 2012 Semantic Text Similarity...
As the increasing application of ICT technology in power system, the information available is getting more and more, which has provided a firm foundation and possibility to the implementation of Active Distribution System (ADS). The key challenges at the ADS planning is how to integration with the optimization operation of DER (generation (DG, RES), Electricity Energy storage (EES) and interactive...
To compensate for the uneven brightness of image caused by the various light sources of optical microscopy, this paper proposes a exposure method for digital microscopic image. Firstly, for uneven illumination of characteristics of the optical microscopic digital imaging systems, it draws gain curve according to no slice of pure background brightness of the image and gains brightness gain equation...
In this paper, a novel crack detection method is proposed based on the digital image of building external wall. We strive to record the wall surface condition accurately, and then get the linear characteristics of the image for crack recognition. This paper first does image edge detection, image binary of adaptive threshold and removal of isolated points, obtaining effective linear characteristics...
Huge code size and poor code density have always been a serious problem in VLIW processor. In order to deal with the problem and its influence on the instruction memory in stream architecture, this paper proposes a novel method called field-divided VLIW compression through analyzing the code characteristics of stream program across a wide range of typical stream application domains and dividing the...
The MapReduce framework has been employed in many papers to process the large-scale graph. In this paper, we propose a multi-source message passing model to achieve multi-source traversal of graph in one iterative progress, which largely improve the parallelism efficiency of graph algorithm involving multi-source traversal which occurs in many complex graph algorithms. As the model can traverse the...
We have employed high resolution synchrotron radiation x-rays 3D imaging techniques, both tomography and laminography, to study the electromigration (EM) failure mechanism in flip-chip solder joints. In these studies, the ex-situ imaging of the early-stage damage evolution at the interface between UBM and solder balls, revealed that the EM induced failure mode of solder joints could be described by...
In this paper, an energy detection scheme based on the pseudo bit error rate (BER) estimation is investigated. In the proposed scheme, the basic strategy is to use the pseudo BER to estimate the signal-noise-ratio (SNR) of primary signal for energy detection at the cognitive users. Threshold and sensing length are updated with the estimated SNR afterward. We have shown that this modified energy detector...
Synchrotron radiation white beam x-ray microdiffraction was employed to study grain size and orientation of fine pitch Sn2.5Ag micro-bumps. The indexing of the Laue patterns shows that there is mostly one dominant grain orientation in each micro-bump. Moreover, a statistics study based on the characterization of 72 micro-bumps, shows that the [001] direction, which is the fast diffusion path for Ni/Cu...
The optimal strategy of financing through warehouse receipt pledging for retailers with capital constraints in the supply chain financing system under demand uncertainties is designed and investigated. We design a supply chain financing system composed of the manufacturer, the retailer and the commercial bank, in which the credit line and bankruptcy probability of the retailer are considered. The...
Montmorillonite, iron oxide and the composite, were synthesized and characterized. The behavior and kinetics of arsenic sorption on the three kinds of adsorbent were investigated under neutral conditions. The results indicated that the sorption capacities of iron oxide are higher than those of montmorillonite and composite. The kinetic data of arsenic adsorption can be well described by Lagergren-second-order...
Modern search engines provide users with suggested query completions. These search suggestions are often ambiguous in nature and could refer to any number of homonyms. Previously we used a static ontology built from data in Wikipedia to address this issue. Here, we present a method for dynamically building an ontology of "famous people" based on mining the suggested completions of a search...
This paper discusses a practical transportation service procurement problem, which is originated from an external project with the department of transportation purchasing at Royal Philips. A combinatorial auction strategy is developed to help the department to determine the annual transportation service procurement cost. Because of a few preset internal and external policies, to settle an optimal...
The social relief system is an important part of the social security system. There have been dual economic and social structure in the current management system, function process and so on. Some social relief forms have not linked up effectively or convergence degree has not tighted enough so that it has not play the whole integrated strength, like the minimum standard of living for urban residents...
In this study, we used a chip-on-chip test vehicle with 30μm pitch lead-free solder micro bump to study the electromigration reliability of solder micro bump interconnection used for 3D chip stacking. The structure of micro bump composed of Sn2.5Ag solder material with Cu/Ni under bump metallization (UBM) was selected. Two types of interconnection were chosen to evaluate the effect of the joint structure...
This paper explores the associations between personality traits and performance indicators. CCA (Canonical Correlation Analysis) is applied to analyze and optimize the correlations between the two groups of original data, find out the maximum canonical correlation coefficient, convert raw variables into canonical variables. Using sample data, the authors make a detailed explanation for modeling process,...
In recent years, insufficient reserves, growing gap between domestic production and consumption, late implementation of strategic petroleum reserves and so on have made China more dependent on oil import and more exposed to uncertain developments in international oil market. Based on the illustration of detailed aspects of oil vulnerability facing China, this paper selects eight quantifiable individual...
Economic growth relies on energy. Accompany with the enhancement of oil vulnerability, it's crucial for China's government to research the relationship between oil security and economic growth. This paper selects eight quantifiable individual indicators to comprehensively measure oil vulnerability of China for the duration of 1997–2008 by means of principal component analysis, and a comparison between...
