Quantifying uncertainty in reliability block diagrams
Reliability analysis yields statistically derived technical system performance estimates. Traditional reliability analysis employs classical statistical techniques predicated upon asymptotic properties of large data sets. Not uncommonly, however, medium to small data sets constrain analysis efforts …

Developing VDM ++ operations from UML diagrams
The Unified Modelling Language (UML) is widely accepted as the standard notationfor Object-Oriented methods. However, one of its major problem is itslack of formal semantics. The development of the Object Constraints Language(OCL) in the last few years seems to be the answer to this problem, but …

Pipe Diagrams for Thompson's Group F
… of Thompson's Group F. We define the set of pipe diagrams and show that this set forms a group isomorphic to F. We use pipe diagrams to prove two theorems about giving a minimal representation for an arbitrary element of F.

Local properties of random link diagrams
… we show that for random prime alternating diagrams, the expected hyperbolic volume is asymptotically linear in the number of crossings. If we do not restrict to prime alternating diagrams, and instead randomize the over/under strand at each crossing, it is known due to work of Chapman that …

FLOW : a programming environment using diagrams
A graphical language is developed as a generalization of the structured flowcharts proposed by Nessi and Shneiderman. This language can be used in the specification of procedures, procedure interfaces and data structures. A software production support environment is then developed using this …

Bluefish: A Grammar of Discrete Diagrams
Discrete diagrams show collections of data objects and the discrete relationships between them, which include not just nominal and ordinal relations, but also more general ones such as the parent-child relation in a tree and the friend-friend relation in a social network. Perceptual grouping …

Recognition of hand drawn chemical diagrams
Chemists often use hand-drawn structural diagrams to capture and communicate ideas about organic compounds. However, the software available today for specifying these structures to a computer relies on a traditional mouse and keyboard interface, and as a result lacks the ease of use, naturalness, …

Interfaces for creating quantitative conceptual diagrams
… in quantitative graphs such as Economics diagrams. The substantial time those tools require to achieve the desired results leads many people to sketch their graphs with pencil and paper instead of using a computer. In this thesis, I address the challenge of designing a software user …

Twofish: Automatic Edit Cascading for Diagrams
Creating and editing diagrams, whether for scientific research, education, or otherwise, is tedious and time consuming. When a user makes a small change to a diagram element, they often have to make additional downstream edits to fully propagate the change to the diagram. This is because these …

Crossing Number Bounds of Mosaic Knot Diagrams
… some previously undocumented link mosaic diagrams. Next we prove an upper and lower bound on crossing number of certain mosaic diagrams of knots in terms of winding number for knot diagrams that make only counterclockwise turns. Next we begin drawing mosaic diagrams that have a more …

Modeling Software Product Lines Using Feature Diagrams
… feature modeling process by introducing feature diagrams. Feature diagrams capture and represent comand variable properties (features) of the software products in a domain, focusing on properties that may vary, which are further used to produce different software products. We present practical …

Trace Diagrams, Representations, and Low-Dimensional Topology
… may be expressed as labelled graphs called trace diagrams. This point-of-view permits diagram manipulation to be used to construct relations on the functions. In the particular case G=SL(2,C), we give an explicit description of the central functions for surfaces. For rank one and two fundamental …

Van Kampen Diagrams and Small Cancellation Theory
… We investigate the connection between Van Kampen diagrams and the small cancellation hypotheses. Groups that have a presentation satisfying the small cancellation hypotheses C'(1/6), or C'(1/4) and T(4) have a nice solution to the word problem known as Dehn’s Algorithm.</a></p>

Study of gold-based alloy phase diagrams

Root-theoretic Young diagrams and Schubert Calculus
… from the common lens of root-theoretic Young diagrams (RYDs). In terms of RYDs, we present nonnegative Schubert calculus rules for the (co)adjoint varieties of classical Lie type. Using these we give polytopal descriptions of the set of nonzero Schubert structure constants for the (co)adjoint …
