Background High-throughput technologies became common tools to decipher genome-wide changes of gene expression (GE) patterns. Functional analysis of GE patterns is a daunting task as it requires often recourse to the public repositories of biological knowledge. On the other hand, in many cases researcher's inquiry can be served by a comprehensive glimpse. The KEGG PATHWAY database is a compilation...
In last years the huge relevance of accessing and acquiring information made available by Web pages and business documents has grown much further. Thus, wrapping information from documents in HTML and PDF formats is receiving increasing interest. In this paper we present a textual query language, named ViQueL, that allows for querying information in both Web and PDF documents on the base of its spatial...
There is an emerging focus on real-time data stream analysis on mobile devices. A wide range of data stream processing applications are targeted to run on mobile handheld devices with limited computational capabilities such as patient monitoring, driver monitoring, providing real-time analysis and visualization for emergency and disaster management, real-time optimization for courier pick-up and delivery...
Researched and developed the software system of Information Management and Decision Support System of the hidden danger troubleshooting of Coal Mine. By using the technology of collaborative software to realize fast circulation of information, dynamic tracking, rapid feedback, and closed-loop management of transaction processing for the hidden danger, and by applying the technology of data mining,...
Nowadays, online social networks host more and more applications in order to provide their users with the possibility of finding everything they need on a single platform. The number and diversity of interactions that take place over time between users and applications within these platforms make these environments very good candidates for learning various types of information about users' interests...
Large amount of social (communication) data have been generated in many applications for personal communication purpose. However, these data have not been used well currently. In this paper, we will introduce a methodology to collect and analyze those personal data, and by this for extracting social networks from the data. A system architecture will also be presented and implemented to show how the...
Pixel-value-differencing (PVD) based steganographic methods, which take into account the characteristic of human visual system, usually lead to large embedding capacity and good visual imperceptibility. In this paper, a recently proposed PVD-based steganography is further studied. First, by deriving a sufficient condition for data embedding/extraction, we show that the method can be generalized, and...
Making the semantic description and automatic semantic annotation of the image which contains rich contents and intuitive expression is a research subject that is challenging. It is a key technology of realizing fast and effective image retrieval and a research focusing on cross media mining. Also it has great application value in various kinds of fields. This paper studies and discusses image media...
In recent years, digital watermarking technologies are considered to be important means to protect digital image copyrights. In this paper, we combine a non-invertible watermark scheme with an HVS model adaptive watermark. The application of adaptive watermarks improves visual imperceptibility. However, we find that an adversary is able to apply ambiguity attacks on the non-invertible watermark scheme...
The growing usage of mobile camera phones has led to proliferation of many mobile applications. Landmark recognition is one of the mobile applications that are gaining more attention in recent years. The main idea of the application is that a user will use a camera phone to capture the image of a landmark or building and then the system will analyze, identify, and inform the user the name of the captured...
Previous proposed steganographic schemes based on tolerable error range (TER) can restrict the distortion caused by data hiding within an acceptable range, but both the stego-image and the original image are necessary for extracting the secret message. This paper presents a novel TER-based steganographic scheme, in which JPEG compression under a certain quality factor is regarded as TER, and the modification...
In video-fluoroscopic swallowing assessment the time taken for the bolus material to transit the oral and pharyngeal regions is currently estimated by visual inspection. This paper presents an effective method for objectively approximating these timings by fitting a Gaussian surface to the first derivative of the intensity profiles along user defined anatomical boundaries. The profile characteristics...
The aims this paper is to display the apriori data mining method results implanted in SINPE?? (Electronic Protocols Integrated System) in an Enteral Nutrition research. We developed the data mining in the SINPE and later the items body mass index (BMI or IMC) and Enteral diet were selected from the database of the Homecare Enteral Nutrition Research. The parameters used were 10% support and 50% confidence...
The augmented k-ary n-cube AQn,k is a recently proposed interconnection network that incorporates an extension of a k-ary n-cube Qnk inspired by the extension of a hypercube Qn to the augmented hypercube AQn (as developed by Choudom and Sunita). We extend a recent topological investigation of augmented k-ary n-cubes by proving that any augmented k-ary n-cube AQn,k is edge-pancyclic and that AQ2,k...
Group awareness information is important information for group work. It represents things such as group members' roles and responsibilities, their positions on an issue, their status, and the state of various group processes that group members know about when they work together. The group awareness information presented in this article is designed to capture group member activities and their behaviors...
Vestibular dysfunction is associated with the developmental delay of motor and attention skills. Integrity of the vestibular and visual systems manifest in rapid side to side eye movement called nystagmus. This may be evoked by physical rotation or caloric stimulation to the ear drums. The approach in this technological advance explores whether controlled rotation of the environment can induce the...
Filmification of methods is a promising concept to find new formats for program and data/knowledge representation. It is also to create a basis for specifying and developing a new generation of programming environments, as well as for introducing new types of educational materials. Within this approach various algorithms are analyzed and represented as cyberFilms where special visual constructs, super-symbols...
Although traditional line illustrations are very abstract representations, they can communicate the form of an object effectively. This is only possible by the use of perceptual cues, mastered by professional artists. To create effective line illustrations from 3D models, it is important to use these perceptual cues to avoid visual dissonance and ambiguity, and also to create visual effects like shading,...
The modeling of weathering effects in still images is a powerful editing tool for many graphics applications. Although most of these effects can be generated by manually creating textures through graphics editing applications, performing such artist work is time consuming. More sophisticated and automatic solutions to simulate a wide variety of weathering effects become essential. We present a method...
