This work focuses on integrated design computation and proposes methodologies and tools to build border designs integrating CAD-CAM technologies. Border patterns are recognized as intervallic and repetitive arrangement of a type of motifs. Further, motif is observed as polar array of a primitive which is a tiny geometric object required for the representation of motif. The designs of different ...

Very high level languages for describing mechanical assembly require a representation of the geometric and physical properties of 3 0 objects including parts, tools, and the assembler itself. This paper describes a geometric modeling system that generates a data base in which objects and assemblies are represented by nodes in a graph structure. The edges of the graph represent relationships amo...

Typically the track network data model is maintained as an afterthought or with primitive tools or complex procedures. A software tool set to manage unified set functions needed to manage a track network is a sizable, complex and costly endeavor and thus difficult to justify. Bentley Systems, a developer of engineering systems software, has had the opportunity of combining work in the highway a...

SONET/WDM networks using wavelength add–drop multiplexing can be constructed using certain graph decompositions used to form a “grooming,” consisting of unions of certain primitive rings. The existence of such decompositions when every pair of sites employs no more than 8 of the wavelength capacity is determined, with few possible exceptions, when the ring size is a multiple of four. The techni...

The formation of the three lineages of the mouse blastocyst provides a powerful model system to study interactions among cell behavior, cell signaling, and lineage development. Hippo signaling differences between the inner and outer cells of the early cleavage stages, combined with establishment of a stably polarized outer epithelium, lead to the establishment of the inner cell mass and the tro...

Text-to-scene conversion requires knowledge about how actions and locations are expressed in language and realized in the world. To provide this knowlege, we are creating a lexical resource (VigNet) that extends FrameNet by creating a set of intermediate frames (vignettes) that bridge between the high-level semantics of FrameNet frames and a new set of low-level primitive graphical frames. Vign...

This thesis analyses the computational capabilities of cellular au-tomata working on periodical con gurations of any dimension. We rst studythe maximal objects these cellular automata can identify ; we call those objectsprimitive roots of periodical con gurations of any dimension. We characterizethem and show some of their properties.Secondly, we present a set of algorithms ...

One of the main tools of cryptography are reductions. The simplest way to prove the security of a complex scheme based on the security of its constituents is to prove that if there exists an adversary that breaks the complex scheme then we can construct an adversary that breaks at least one of the constituent primitives. Since the security of the primitive is taken as a premise, this gives a co...

An exposed approach in computer service architecture is one that offers client software a primitive service whose semantics are closely based on the underlying physical infrastructure. The exposed approach relies on the client to build higher-level services, with more abstract semantics, out of such primitive tools using sophisticated compilation or run-time algorithms. Current approaches to re...
