Following on the success earlier this year, this Web-to-host integration project will offer enhanced access to tried and true.MODCOMP will employ its powerful ViewMax technology to re-engineer the workflow and user interface of three of Cornells mission-critical, mainframe-based functions.The two-phase project, scheduled for early 2002 deployment, will consolidate functions, streamline views, clarify input requirements and optimize computing and processing resources across the old and new systems, without any modification to the mainframe.While they do a good job of processing data, the programs are hard to learn, cumbersome to use, and are by no means up to todays standards for usability.
Because of our past success working with MODCOMP, we knew they could build a user-friendly, browser-based interface that will eliminate training time, reduce data input and navigation errors, and make critical information more accessible and usable to faculty and staff. With this project, we leverage Internet technology to create client-side modeling which permits the testing of various budgeting and planning scenarios within the browser before they are integrated into the mainframe application.

Canadian Journal of Civil Engineering, 2008, 35(1): 57-66, Abstract Efforts have been made in this paper to backcalculate the in situ elastic moduli of asphalt pavement from synthetically derived falling weight deflectometer (FWD) deflections at seven equidistant points. An artificial neural network (ANN) is used as a tool for backcalculation in this work. The ANN is observed to backcalculate layer moduli, both from normal as well as noisy deflection basins, with better accuracy compared with other software, namely, EVERCALC and ExPaS. Work have been extended further to develop ANN models that can predict a possible rigid layer at the bottom of the pavement and can directly predict the remaining life of the pavement without backcalculating the layer moduli. Finally, a reliability analysis is performed to quantify the performance of backcalculation using an ANN.
