An Enterprise Architecture (EA) embraces an organization"! technical infrastructure, applications, business capabilities, and relationships among them. Evolutionary design is a common characteristic for such an EA. An EA can be considered as a complex system of systems, whereas the actual efforts for its maintainability and evolution have a high influence on the enterprise"s capability to quick...

In this paper, we present ViBBA (Visual Bean Based Animator), a toolbox supporting the automatic model driven animation [7] consisting in automatically deriving scenarios exposing critical system behaviors from requirements specifications, and animating those scenarios through a graphical interface. ViBBA allows visual construction of graphical animators and scenarios animation. It is integrate...

A real-time, face tracker based on both sound and visual cues is presented. Initial talker locations are estimated acoustically from microphone array data while precise localization and tracking are derived from visual data. The image processing employs a hierarchical structure which utilizes source motion, contour geometry, color data, and facial features. The resulting system is capable of tr...

With the flood of data produced by today’s information systems, something must be done to allow business decision-makers to extract the information the data contains. The recent advances in visualization technologies provide the capability to begin to use human visual/spatial abilities to solve the abstract problems found in business. If business problems can be visualized with an appropriate r...

This paper reports on a wearable Hyperboloidal Head Mounted Projective Display (HHMPD) and two user studies on the evaluation of visual quality of a wearable HHMPD. Using a hyperboloidal mirror, an HHMPD can provide a wide field-ofview (FOV), a large observational pupil, and optical see-through capability. We propose a simple head attached screen that is both retro-reflective and semi transpare...

We present an architecture for the online learning of object representations based on a visual cortex hierarchy developed earlier. We use the output of a topographical feature hierarchy to provide a viewbased representation of three-dimensional objects as a form of visual short term memory. Objects are represented in an incremental vector quantization model, that selects and stores representati...

Effects of the social environment on age at sexual maturation are assumed to require direct interactions, such as suppression of subordinates through aggression from dominants. Using green swordtails (Xiphophorus helleri), we demonstrate for the first time that females and males adjust their age at maturation in response to visual cues of male sexual ornamentation in the current environment: fe...

multivariate process capability indices (mpci) show how well a manufacturing process can meet specifica-tion limits when quality characteristics enclose a relative correlation. process capability is an important and commonly used metric for assessing and improving the quality of a production process. when quality charac-teristics of a product are correlated then an attractive comes close to mpc...

An approach is presented for the evolutionary development of supervised autonomous navigation capabilities for small "backpackable" ground robots, in the context of a DARPA-sponsored program to provide robotic support to small units of dismounted warfighters. This development approach relies on the implementation of a baseline visual servoing navigation capability, including tools to support op...

This paper is presenting a betterment steganographic method for covert channel communication. Two distinct methods are combined to achieve possibly high data hiding capability with high visual quality. The proposed method shifts the last n nonzero AC coefficients from S JPEG block, and changes the magnitude values of the first n nonzero AC coefficients from T JPEG blocks. S and T blocks are det...
