Several differences between DASYLab® LabVIEW are discussed. DASYLab® is easy-to-use software that process data in defined blocks, which are the result of a measurement or derived data blocks of measurements. DASYLab® data wires pass complete data blocks, which are complex data structures containing the measurement data along with additional information such as scan rate and channel information and in LabVIEW, the additional information is handled in the design of the program. LabVIEW is a complete graphical programming language and DASYLab® is a collection of preprogrammed functions. DASYLab® provides an externally modulated generator that can be defined to have as many as 16 channels with a selectable wave shape.

Motivation: In Systems Biology, an increasing collection of models of various biological processes is currently developed and made available in publicly accessible repositories, such as biomodels. net for instance, through common exchange formats such as SBML. To date, however, there is no general method to relate different models to each other by abstraction or reduction relationships, and this task is left to the modeler for re-using and coupling models. In mathematical biology, model reduction techniques have been studied for a long time, mainly in the case where a model exhibits different time scales, or different spatial phases, which can be analyzed separately. These techniques are however far too restrictive to be applied on a large scale in systems biology, and do not take into account abstractions other than time or phase decompositions. Our purpose here is to propose a general computational method for relating models together, by considering primarily the structure of the interactions and abstracting from their dynamics in a first step. Results: We present a graph-theoretic formalism with node merge and delete operations, in which model reductions can be studied as graph matching problems. From this setting, we derive an algorithm for deciding whether there exists a reduction from one model to another, and evaluate it on the computation of the reduction relations between all SBML models of the biomodels. net repository. In particular, in the case of the numerous models of MAPK signalling, and of the circadian clock, biologically meaningful mappings between models of each class are automatically inferred from the structure of the interactions. We conclude on the generality of our graphical method, on its limits with respect to the representation of the structure of the interactions in SBML, and on some perspectives for dealing with the dynamics.

This paper presents solution of selected problems using principle of duality and projective space representation. It will be shown that alternative formulation in the projective space offers quite surprisingly simple solutions that lead to more robust and faster algorithms which are convenient for use within parallel architectures as GPU (Graphical Processor Units-NVIDIA-TESLA/ Fermi) or SCC (Intel-Single-chip Cloud Computing), which can speed up solutions of numerical problems in magnitude of 10-100. There are many geometric algorithms based on computation of intersection of lines, planes etc. Sometimes, very complex mathematical notations are used to express simple mathematical solutions, even if their formulation in the projective space offers much more simple solution. It is shown that a solution of a system of linear equations is equivalent to generalized cross product, which leads with the duality principle to new algorithms. This is presented on a new formulation of a line in 3D given as intersection of two planes which is robust and fast, based on duality of Plücker coordinates. The presented approach can be used also for reformulation of barycentric coordinates computations on parallel architectures. The presented approach for intersection computation is well suited especially for applications where robustness is required, e.g. large GIS/CAD/CAM systems etc.

Cross-media communications are integrated, interactive experiences that occur across multiple media, with multiple authors and have multiple styles. The audience becomes an active part in a cross-media experience, that can occur across the Internet, video and film, broadcast and cable TV, mobile devices, DVD, print, and radio. It has the potential to offer more immersive and engaging experiences where people are able to engage as much, or as little, as they like. Cross-Media Communications was recently published to present an informed look. Throughout the book, there are information graphics and interpretive illustrations of each chapter, providing opportunities to reflect on the readings from a more visual perspective. An inspiration for this book comes in part from my involvement with the Entertainment Technology Center (ETC) at Carnegie Mellon University. Interpretive Illustrations summarize each chapter and the book as a whole.

In Augmented Reality applications, the human perception is enhanced with computer-generated graphics. These graphics must be exactly registered to real objects in the scene and this requires an effective Augmented Reality system to track the user's viewpoint. In this paper, a robust tracking algorithm based on coded fiducials is presented. Square targets are identified and pose parameters are computed using a hybrid approach based on a direct method combined with the Kalman filter. An important factor for providing a robust Augmented Reality system is the correct handling of targets occlusions by real scene elements. To overcome tracking failure due to occlusions, we extend our method using an optical flow approach to track visible points and maintain virtual graphics overlaying when targets are not identified. Our proposed real-time algorithm is tested with different camera viewpoints under various image conditions and shows to be accurate and robust.

The maritime sector with its wide spectrum of ancillary conditions can benefit from advanced computer graphics in many ways. The paper presents several applications from marketing over design to training and maintenance that are based on virtual or augmented reality technology. Some of the technical challenges that arise from the ambitious environment are sketched and an outlook on future research and development is given.

The article discusses the use of computer graphics in order to enthrall students to study classroom subjects like computer science and mathematics. Accordingly, students were introduced to the subjects through the use of colorful, highly visual media and processes to apply numerical systems to the world. Although the process is conventional, in the course of time it is claimed that those subjects gradually become an abstract art more akin to wizardry than science. To address the problem, the use of computer graphics is suggested. For instance, to encourage student retention in computer science, the National Science Foundation has sponsored a Research Experience for Undergraduates Site. In the of the program, it was realized that the students become interested in learning other disciplines.
