Composing With Nodal Networks
نویسندگان
چکیده
Issues related to compositional technique using the software environment Nodal are discussed. The particular focus in this paper is the use and characterisation of nodal networks. These networks are the generative engine of Nodal. Network configuration is explored by discussing the compositional process for the work “Network Study #1” that employs Nodal exclusively. Observations are made regarding the transformational properties of simple networks.

Predicting Deficient Condition Performance of Water Distribution Networks
A water distribution network is subjected to various abnormal conditions such as pipe breaks, pump failures, excessive demands etc. in the design period. Under such conditions, the network may not be able to meet required demands at desired pressures, and becomes deficient. Traditional network analysis assumes nodal demands to be satisfied and available nodal pressures are calculated. However, ...
متن کاملHead-Driven Simulation of Water Supply Networks
Up to now most of the existing water supply network analyses have been based on demand-driven simulation models. These models assume that nodal outflows are fixed and are always available. However, this method of simulation neglects the pressure-dependent nature of demand that is characterized by changes in actual nodal outflows particularly during critical events like major mechanical or hydra...
متن کاملارائه روشی نوین جهت تخمین میزان نشت در شبکههای آبرسانی به کمک تحلیل فشارهای گرهی
The water supply networks have always been of significance to researchers as a hydraulic system of transferring and distributing water. The pressure gradient is the main reason of water transfer in networks, and in case of non-standard pressure increase, the undesirable phenomenon of leakage occurs in the network. Leakage in urban water distribution networks causes water waste and enormous fina...
متن کاملInverse nodal problem for p-Laplacian with two potential functions
In this study, inverse nodal problem is solved for the p-Laplacian operator with two potential functions. We present some asymptotic formulas which have been proved in [17,18] for the eigenvalues, nodal points and nodal lengths, provided that a potential function is unknown. Then, using the nodal points we reconstruct the potential function and its derivatives. We also introduce a solution of i...
متن کاملThe uniqueness theorem for inverse nodal problems with a chemical potential
In this paper, an inverse nodal problem for a second-order differential equation having a chemical potential on a finite interval is investigated. First, we estimate the nodal points and nodal lengths of differential operator. Then, we show that the potential can be uniquely determined by a dense set of nodes of the eigenfunctions.
