متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Expressive Power of the Schematic Protection Model
In this paper we show that the Schematic Protection Model (SPM) subsumes several well-known protection models as particular instances. We show this for a diverse collection of models including the Bell-LaPadula multi-level security model, take-grant models, and grammatical protection systems. Remarkably SPM subsumes these models within its known e ciently decidable cases for safety analysis (i....
متن کاملA Schematic Model of Generations of Quarks and Leptons
We propose a model of generations that has exactly three generations. This model has several attractive features: There is a simple mechanism to produce the CKM quark mixings and their neutrino analogs. There are definite predictions for particles of much higher mass than the quarks and leptons of the standard model, including the prediction of two-body decays without missing mass for the highe...
متن کاملThe Generation of Schematic Diagrams from Geographic Representations of Networks
Often, the geographic view of a network hides important connectivity information found in the network. In these cases a schematic diagram of the network data provides a representation in which connectivity relationships are highlighted. In this paper we explore issues relating to the development of information systems that not only support schematic representations of network data, but also all...
