In this paper, we study an automatic testing system for public cloud on data security risks. To this end, we first establish a framework based on SOA (Service Oriented Architecture), which provides a capability to proceed data security tests on cloud automatically. Second, based on the framework we implement a cloud security testing system, which includes data confidentiality test and data deletion...
In the recognition of osteosarcoma magnetic resonance images (MRI), the probability of a pixel belonging to a class is not only related to its own features, but also closely correlated with the information distribution of the surrounding pixels. However, it is currently unable to recognize the osteosarcoma lesions and surrounding issues simultaneously. In order to solve the problem, we propose a fully...
Improving the performance of statistical machine translation is often a significant problem, especially in low language resource scenarios such as Chinese-Mongolian SMT. In this paper, we propose a method to improve the performance of Chinese-Mongolian SMT system using multi-word expressions, which is also a pilot study for this language pair. We extract MWEs from the phrase-table then integrate the...
Ischemic stroke is a high prevailing disease and costly in industrialized countries. A valid animal model is essential to develop an extensive research. Among various models, we choose middle cerebral artery occlusion (MCAO) model as it is one of the common used ischemic stroke animal models. The purpose of our study is to investigate the optical properties of ischemic stroke by near infrared spectroscopy...
An improved equivalent static loads method (ESL) for interval parameters structures is proposed based on local equivalence. In this method, the reliability-based dynamic response topology optimization is solved in the time domain. While calculating the improved ESLs, two measures are taken to prevent the uncertainty from increasing in the process of interval arithmetic. Firstly, only the uncertainty...
The algorithm of line segment intersection is the core algorithm for vector map overlay. The traditional method is based on the plane-sweep process to find the intersections of two groups of lines. Although such method proves to be efficient in serial system, the basic data structure of this kind of algorithm needs to maintain a tree structure, which has the data-lock in multi-core system. In addition,...
Based on the detailed analysis of M-Module specification and PCI specification, this thesis design a kind of M-Module carrier which based on PCI bus. The design use FPGA as core controller in the design of hardware to decrease difficulty and cost. The design used IP core to control PCI interface and developed firmware for M-Module interface. This design solved a series of problems such as the problem...
The ground slope face supposed Prantle's slope face. the computation of static earth pressure is enlarged seismic earth pressure. By employing pseudo-static approach and the method of limit equilibrium,the seismic bearing capacity of strip foundation on the composite foundation is derived. The computing methods of the seismic bearing capacity of the composite foundation on layering ground, rectangular...
Deep excavation and supporting structure is a space system which has Length, width and depth. Spatial effect should be considered in the design of deep excavation. The concept of utilization factor of soil pressure is proposed and calculation method of utilization factor of soil pressure is established based on conventional design methods on deep excavation of plane strain problem. Comparison of an...
COTS (Commercial off-the-shelf) ERP systems provide a lot of reusable software packages, which accelerate the implementation process to some extent. However they also put enterprises into a dilemma: whether to adapt as-is business processes or to customize software packages. In order to help the enterprises get out of the dilemma, a holistic methodology is proposed to automatically elicit software...
The mobile ad hoc networks have the characteristics hidden / exposed terminals and single channel. This paper not only analysis the cause of hidden / exposed terminals and the single-channel, but also described mac layer main access protocol in the current ad hoc network. And in a single channel circumstances, analyzed the agreement of the hidden / exposed terminal situation. Finally, in the article...
With the development of Internet and computation technique, many areas begin to process their own area data more accurately. Especially, oil field area involves many disciplinary area data, such as physical geography disciplinary, geological disciplinary, reservoir engineering disciplinary and so on, data from simple character type to complex bulk data volume type. How to effectively manage these...
The paper presents an improved Genetic algorithm for the topology optimization of trusses to minimize the weight with stress and displacement constraints under multiple load cases. Based on given planar nodes, the initial population of Genetic algorithm, i.e., the topology of truss structures is generated by Delaunay triangulation and heuristic method. This method can ensure the feasibility and diversity...
