Authorization bugs, when present in online social networks, are usually caused by missing or incorrect authorization checks and can allow attackers to bypass the online social network's protections. Unfortunately, there is no practical way to fully guarantee that an authorization bug will never be introduced—even with good engineering practices—as a web application and its data model become more complex...
Projects receive a large number of bug reports, and resolving these reports take considerable time and human resources. To aid developers in the resolution of bug reports, various automated techniques have been proposed to identify and recommend developers to address newly reported bugs. Two families of bug assignee recommendation techniques include those that recommend developers who have fixed similar...
A lot of study has been done on the voice QoE (Quality of Experience). However, QoE study on the background of Chinese language is scarce. PESQ (Perceptual evaluation of speech quality) is a well known objective method for the voice QoE evaluation, it is approved as ITU-T P.862 Recommendations. This paper research the accuracy of PESQ in evaluating speech codec in Chinese environment. Two 3G speech...
Step-by-step and from-easy-to-difficult are the outstanding characteristics of geological interpretationof remote sensing images. The interpretation results, especially the attributes of interpreted features, can be changed or adjusted on each step according to the reference materials and the field work feedback. As aconsequence, geological interpreters may make a lot of attribute adjustments and...
Distributed metadata management is an efficient way to address the huge data of mineral information resources, which are usually distributed stored. In this paper, existing related metadata standards of mineral resource are firstly explored, based on which three typical kinds of metadata management mode, centralized metadata management mode, distributed metadata management mode and shared metadata...
Three-dimension geological simulation engine is the key to geological environment simulation which can visually support geological resource exploration and analysis. Design of a three-dimension geological simulation engine is presented in this paper firstly. The engine is then fully implemented and applied in a case study in the southern margin of Yili basin to verify its feasibility. In the case...
This paper discusses a metamorphosis method for temporal data mining. We propose definition of temporal type and time granularity to divide into segments for time, then build an event temporal space which may describe something change of data over time. We give the conception of metamorphosis data in event temporal types space so that it is easier to discover valuable knowledge, but it is not clear...
