the dynamic nature of projects and the fact that they are carried out in changing environments, justify the need for their periodic monitoring and control. collection of information about the performance of projects at control points costs money. the corrective actions that may need to be taken to bring the project in line with the plan also costs money. on the other hand, penalties are usually...

With the acceleration of urbanization in a river basin, changes underlying surface structure basin are more and intense, which causes frequent floods. This article aims to analyze applicability HEC-HMS model flood simulation basins influence land use on catchment runoff. Pu River Basin is typical taken as research project. Based changes, soil types, long-term hydrological data Basin, constructe...

Real-time measurement of tire-road friction coefficient is extremely valuable for winter road maintenance operations and can be used to optimize the kind and quantity of the deicing and anti-icing chemicals applied to the roadway. In this project, a wheel based tire-road friction coefficient measurement system is first developed for snowplows. Unlike a traditional Norse meter, this system is ba...

Abstract: The problem of minimizing l2-sensitivity subject to l2-scaling constraints for two-dimensional (2-D) separable-denominator state-space digital filters is investigated. The coefficient sensitivity of the filter is analized by using a pure l2-norm. An iterative algorithm for minimizing an l2-sensitivity measure subject to l2-scaling constraints is then explored by introducing a Lagrange...

Abstract: An important issue in the design of a neural network is the sensitivity of its output to input and weight faults. In this paper, new fault metrics for sensitivity analysis is derived. The experimental derivation of the derived fault metrics is demonstrate that upper bound envelop exist with empirical error of the neural network. Correlation coefficient between MEANWSZ and derived sens...

We describe the use of parametric amplification to substantially increase the magnetoelectric (ME) coefficient of multiferroic cantilevers. Parametric amplification has been widely used in sensors and actuators based on optical, electronic, and mechanical resonators to increase transducer gain. In our system, a microfabricated mechanical cantilever with a magnetostrictive layer is driven at its...

This work was one of the tasks of the Manufacturing2Client project, whose objective was to develop a frontal deflector to be commercialized in the automotive industry, using new project and manufacturing methods. In this task, in particular, it was proposed to develop the ability to predict computationally the aerodynamic influence of flow in vehicles, in an effort to reduce fuel consumption in...
