Complex Objects Made Simple

چکیده
This paper describes the interaction and object representation features of the visual database editor ESCHER which is based on the nested relational data model. In particular we like to indicate the multiple two-dimensional cursors and their way of moving in and out of nested objects, cut-and-paste operations, the QBE-like query mechanism, interactive schema design, and the unusual, self-referential way of inspecting schemas as regular objects under the meta-schema. Emphasis is placed on screen shots from the prototype which should give the reader a feeling for the power of both the data and the interaction model.

Visual cryptography is a method that makes use of the characteristics of human vision and it requires neither the knowledge of cryptography nor the complex calculations. This method was first proposed by Naor and Shamir, its implementation is simple, it has been extended to an secrect sharing (k, n) in which n shares are made from the image and they are distributed among n participants. Moreov...

Due to the complex corrosion mechanism of the bronze objects, explaining the structure of different layers of corrosion in these objects at microscopic levels is possible. Typically copper oxide(I) is the first corrosion layer on surface of bronze objects that are excavated of historical sites. However, depending on the environmental conditions، various forms of corrosion layer of tin or copper...
متن کاملSoliton-like Solutions of the Complex Non-linear Klein-Gordon Systems in 1 + 1 Dimensions
In this paper, we present soliton-like solutions of the non-linear complex Klein-Gordon systems in 1+1 dimensions. We will use polar representation to introduce three different soliton-like solutions including, complex kinks (anti-kinks), radiative profiles, and localized wave-packets. Complex kinks (anti-kinks) are topological objects with zero electrical charges. Radiative profiles are object...
متن کاملKohonen Self Organizing for Automatic Identification of Cartographic Objects
Automatic identification and localization of cartographic objects in aerial and satellite images have gained increasing attention in recent years in digital photogrammetry and remote sensing. Although the automatic extraction of man made objects in essence is still an unresolved issue, the man made objects can be extracted from aerial photos and satellite images. Recently, the high-resolution s...
متن کاملVisual working memory for line orientations and face identities.
Previous studies have shown that the number of objects we can actively hold in visual working memory is smaller for more complex objects. However, complex objects are not just more complex but are often more similar to other complex objects used as test probes. To separate effects of complexity from effects of similarity, we measured visual memory following a 1-sec delay for complex and simple ...
