  • DSC: software tool for simulation-based design of control strategies applied to wastewater treatment plants

    This paper presents a computer tool called DSC (Simulation based Controllers Design) that enables an easy design of control systems and strategies applied to wastewater treatment plants. Although the control systems are developed and evaluated by simulation, this tool aims to facilitate the direct implementation of the designed control system to the PC of the full-scale WWTP (wastewater treatment ...

  • A distributed modelling framework for large-scale microscopic traffic simulation

    Simulation modelling is an increasingly popular and effective tool for analysing transportation problems, which are not amendable to study by other means. In this paper, we examine the need for distributed simulation from the perspective of computational speedup and development of large-scale network simulation contexts and datasets. After an overview of the general techniques for the distributed ...

  • Optimal control model of technology transition

    This paper discusses the use of optimisation software to solve an optimal control problem arising in the modelling of technology transition. We set up a series of increasingly complex models with such features as learning-by-doing, adjustment cost, and capital investment. The models are written in continuous time and then discretised by using different methods to transform them into large-scale ...

  • Evaluating Modeling Software - The Hidden Features that Determine the True Cost/Benefit

    There is general agreement that the costs/benefit balance of hydraulic modeling is now heavily in its favor.  The massive advances in both speed of build and ease of use over recent years make modeling the best approach to a far greater range of issues than was the case even a few years ago.  However, as many users know as they try to select modeling software, comparative evaluations of ...

  • Why Need Dedicated Servers to Boost Business?

    When businesses expand, there comes the need to increase your resources for effective running of the organization. It is not possible for any company to scale up their business without investing further in other required resources. When you deal with thousands of requests per second and terabytes of traffic per day, you have to get rid of your existing shared hosting plan and shift to a dedicated ...


  • Statistical analysis of histopathology endpoints

    Histopathological assessments of fish from aquatic ecotoxicology studies are being performed with increasing frequency. Aquatic ecotoxicology studies performed for submission to regulatory agencies are usually conducted with multiple subjects (e.g., fish) in each of multiple vessels (replicates) within a water control and within each of several concentrations of a test substance. A number of ...

  • A heuristic approach to particle flows in complex terrain

    A heuristic approach based on emulating the Navier-Stokes equations is proposed for a shorthand description of flows of airborne particle in complex terrain. The exercise is motivated by the need for a simple, computer-inexpensive, yet comprehensive and flexible model to support a software package on nuclear accident consequence assessment, currently in development at IFA-Bucharest. Central to ...
