AdLocus is an APP developed by HyXen Company for mobile advertisements. This advertising software can push the message to the target users within specified locations. Based on the real big data provided by AdLocus, we design a dynamic advertisements recommendation system to increase the advertising efficiency. The proposed method uses the regression models and the click probability to recommend the...
System Testing is a key technology of CVIS (Cooperative Vehicle Infrastructure System). A shortest test sequence generating approach in CVIS is proposed in this paper. The paper firstly analyzes the spatial-temporal state of vehicle and complexity of infrastructure in network. Then paper designs system features and test cases, and introduces the concept of support index of the test case to system...
Currently, most of the human detection methods are based on low-level features. In this paper, we proposed a middle-level feature generation method based on non-negative matrix factorization (NMF) for human detection. We also proposed an improvement scheme to guarantee that a better middle-level feature can be achieved. The proposed scheme can be applied to a complex background and the experimental...
Graphical User Interface (GUI) application is a kind of typical event-driven software (EDS) that transforms state according to input events invoked through a user interface. It is time consuming to test a GUI application since there are a large number of possible event sequences generated by the permutations and combinations of user operations. Although some GUI test case prioritization techniques...
How to study more efficiently and maintain the lasting memory of knowledge has long been a contentious hot focus, particularly in the education of Internet era such as the massive open online Courses. Recently, many researchers have pointed out that studying and remembering have good spacing effect, and proposed various models including the effect. However, it does not consider the importance of testing...
This paper proposes an efficient method to solve Hashi, a logical-type puzzle game with N by M grid. By using two methods, intersection method and elimination search, we can solve Hashi quickly and efficiency. The solver is authenticated by solving problems taken from Internet.
In the process of testing Component-based software, Oracle problem comes into existence frequently because of the diversity of component running environment and complicated interactions among components. In this paper, we exploit the features of the component-based software and metamorphic testing (MT) to alleviate the issues. The metamorphic class will invoke relevant component to execute test cases...
Modular methodologies and lambda calculus have garnered limited interest from both analysts and statisticians in the last several years. In this work, we verify the understanding of board general testing system based on PXI Bus, our new framework for general testing system, is the solution to all of these obstacles.
Translation-based steganography (TBS) is a kind of famous text steganography. In this paper, we examine the robustness of TBS and give an effective detection algorithm for TBS. Our algorithm can not only distinguish between natural language text and stego-text which was generated by TBS, but also can distinguish between machine translated text and stego-text. The detection accuracy increases as the...
Linguistic steganography is a technique for hiding information into text carriers. Most of the previous work on linguistic steganography was focused on steganography and there were few researches on steganalysis. Research on attacking methods against linguistic steganography plays an important role in information security (IS) area. In this paper, a linguistic steganography detection algorithm based...
In order to capture the inner-surface cloud of pipe figure components with different material rapidly and efficiently, a new cloud capturing system based on computer vision for inner-surface of pipe figure components was designed. Firstly, the IIRDL (Integrated Inner-reflection Ringy Discrete Laser-spot) method was proposed, which combined the merits of the LSS (Laser Single-spot Scanning) method,...
