Dyes like Brilliant Blue have similar adsorptive behaviour as some organic contaminants, e.g., pesticides. Bromide ions, on the other hand, move much like NO3-N (fertilizer) in soil. Consequently, by using these two tracers, it is possible to in a general way mimic how organic contaminants and fertilizers may move through soils. Three plots with sandy soil in semiarid Tunisia were irrigated dur...

in this paper, we consider a stochastic time-cost tradeoff problem (tctp) in pert networks for project management, in which all activities are subjected to a linear cost function and assumed to be exponentially distributed. the aim of this problem is to maximize the project completion probability with a pre-known deadline to a predefined probability such that the required additional cost is min...

Laguerre function has many advantages such as good approximation capability for different systems, low computational complexity and the facility of on-line parameter identification. Therefore, it is widely adopted for complex industrial process control. In this work, Laguerre function based adaptive model predictive control algorithm (AMPC) was implemented to control continuous stirred tank rea...

As for the problems of complexity and long cycle in the DWDM design, part of problems needed to be considered in DWDM system design were analyzed. An optimized point-to-point DWDM transmission system was designed. Optical fiber communication system with 40Gbit / s and 32 channel was designed and simulated by Optisystem. Based on the study above, the model witch can inhibit dispersion and fiber ...

in previous studies we first concentrated on utilizing crisp simulationto produce discrete event fuzzy systems simulations. then we extendedthis research to the simulation of continuous fuzzy systems models. in this paperwe continue our study of continuous fuzzy systems using crisp continuoussimulation. consider a crisp continuous system whose evolution depends ondifferential equations. such a ...

While small topology simulations are important for validation and educational purposes, large-scale network simulations are a fundamental part of active networking research. Therefore, it is important for a network simulator to provide scalable and efficient solutions to execute these types of scenarios. Using standard sequential simulation techniques, large-scale topologies with substantial ne...

1. Signal integrity 2. Board skew and the contributing factors 3. Return path discontinuities As bus speeds have increased, signal integrity analysis has become more important. A detailed model of the design reduces the total cost of the development because it ensures system functionality from the start. A model maximizes performance while reducing test and debug time. Signal integrity analysis...

Two-point incremental forming method is considered a modern technique for manufacturing shell parts. The presence of bottom punch during the process makes this technique far more complex than its conventional counterpart i.e. single-point incremental forming method. Thus, the numerical simulation of this method is an essential task, which leads to the reduction of trial/error costs, predicts th...
