Though database applications are evolving there are presently only very few system for rapid development of more general interactive visual front-ends. Tailoring non-standard graphical user interfaces to di erent views of a database is always an error prone and time consuming activity. Database frameworks like Microsoft Access, Borland Paradox, or Visual dBase come with basic graphical user int...

A number of interfaces, based on different techniques which better exploit the human senses, have been recently suggested and implemented so enlarging the bandwith of the man-machine communication channel. The availability of graphical devices at low cost has given rise to a large diffusion of visual interfaces. The database field is particularly suited for such interfaces mainly because the da...

data visualization is the process of transforming data, information, and knowledge into visual form, making use of humans’ natural visual capabilities which reveals relationships in data sets that are not evident from the raw data, by using mathematical techniques to reduce the number of dimensions in the data set while preserving the relevant inherent properties. in this paper, we formulated d...

Many recent proposals in the literature present easyto-use query languages, based on visual representations of the database and direct manipulation mechanisms. Such proposals essentially deals with conventional query operations, whereas little effort is devoted to investigate friendly environments for querying temporal databases. Nevertheless, temporal aspects are generally considered extremely...

background bladder reconstruction in the pediatric population is challenging for many reasons, including perioperative complications and readmissions. objectives on a national scale, determine readmission rates at 30, 60 and 90 days after bladder reconstruction in a pediatric population over a 7-year period, evaluating the influence of hospital and patient-specific variables. patients and metho...

Query By Visual Example (QBVE) has been widely exploited in image retrieval. Global visual similarity as well as points of interest matching have proven their efficiency when example image/region is available. If starting image is missing, the Query By Visual Thesaurus (QBVT) paradigm offsets it by allowing the user to compose his mental query image through visual patches summarizing the region...

This paper investigates interactions between audio and visual cues to friendliness in questions in two perception experiments. In the first experiment, manually edited parametric audio-visual synthesis was used to create the stimuli. Results were consistent with earlier findings in that a late, high final focal accent peak was perceived as friendlier than an earlier, lower focal accent peak. Fr...

We describe the design, implementation and user evaluation of QUIVER, a graph-based visual query language for object databases. The design goals of QUIVER include compliance to standards, comprehensive representational power, and consistency of visual representation. Compliance to standards is achieved through QUIVER queries being translated to OQL, the standard query language proposed by the O...

An integrated visual modeling and simulation tool called Component-based System Modeling and Simulation (CoSMoS) is extended to support behavioral specification of parallel atomic DEVS model. An approach based on Statecharts and Graphical Modeling Framework has been developed and implemented for specifying behaviors of atomic models. One or more Statecharts can be developed for any atomic model...
