Abstract:

One of the urgent tasks for wastewater reclamation plants (WRPs) is to develop a cost effective infrastructure upon the existing facilities to meet the new regulations on the concentration of total ammonia nitrogen required by USEPA by 2014.

Abstract:

Today's computer systems are mostly built with volatile memory components such as flip- flops, SRAM, and SDRAM, except for secondary non-volatile storage. As a result, traditional computer systems quickly lose information stored in memory if the power supply is interrupted even for a short period of time. Unfortunately, such volatile devices present significant limitations for computations on embedded cyber-physical systems that have to rely on unreliable power sources.

Visible to the public A CPS Approach to Robot Design

Abstract:

Analytically predicting the behavior of physical systems is generally not possible. For example, the three dimensional nature of physical systems makes it provably impossible to express closed--form analytical solutions even simple systems. This limitation makes experimentation the primary modality for designing new cyber--physical systems.

Abstract:

One grand challenge facing the nascent field of cyber-physical systems is the human-machine interface. Complex systems such as teleoperated space robots, telesurgery robots, and wheel-chair mounted assistive robots involve various levels of human intervention and proximity of the human operator to the artificial system.

Visible to the public Sequential Supervised Learning

Abstract:

We propose concepts for intelligent, adaptive cyber-physical systems that adaptively control information acquisition through the choice of sensor configurations to interact with the physical environment. Our focus is on a novel aspect of cyber-physical systems, intelligent sensing, to control information acquisition under sensing budget constraints in support of critical decision tasks.
