Real time control of urban groundwater levels

Real-Time Control of Urban Water Systems

This paper presents a review of the current state of the art of real time control (RTC) of urban water systems with emphasis on wastewater and urban drainage issues. The paper provides concise definitions of terms frequently used in the literature. Control options for the transport and treatment systems are discussed. Recent developments of the integration of the complete urban wastewater and d...

A comparison study of two different control criteria for the real-time management of urban groundwater works.

We present the comparison of two control criteria for the real-time management of a water well field. The criteria were used to simulate the operation of the Hardhof well field in the city of Zurich, Switzerland. This well field is threatened by diffuse pollution in the subsurface of the surrounding city area. The risk of attracting pollutants is higher if the pumping rates in four horizontal w...

Fuzzy Motion Control for Wheeled Mobile Robots in Real-Time

Due to various advantages of Wheeled Mobile Robots (WMRs), many researchers have focused to solve their challenges. The automatic motion control of such robots is an attractive problem and is one of the issues which should carefully be examined. In the current paper, the trajectory tracking problem of WMRs which are actuated by two independent electrical motors is deliberated. To this end, and ...

Wikicity: Real-time Urban Environments

Real Time Rendering of Populated Urban Environments

Introduction The wide use of computer graphics in games, entertainment, medical, architectural and cultural applications, has led it to becoming a prevalent area of research. At the current stage of technology, users can interactively navigate through complex, polygon-based scenes rendered with sophisticated lighting effects and high quality antialiasing techniques. Animated characters (or agen...
