On the macro scale, feedback control is routinely applied to improve performance and enable new tasks in complex and uncertain systems operating in noisy environments. Our lab has focused on applying feedback control ideas to systems on the micro scale. Here we show how control methods can improve existing performance in the UCLA lab-on-a-chip electrowetting system and can create entirely new capabilities in our 'micro fluidic tweezers' cell steering devices.In the Electro-Wetting-On-Dielectric (EWOD) system developed at UCLA by CJ Kim, a grid ....etc

The Need to Forecast

When the result of an action is of consequence, but cannot be known in advance with precision, forecasting may reduce decision risk by supplying additional information about the possible outcome. The potential benefit of forecasting lies in the realm of decision making to exert control over some process. To be able to look into future is always a question in mind of decision makers. Calculating the likely value of a variable or its likely behavior are important outcomes of fore ....etc

The primary objective of a design engineer is to ensure a safe, efficient design of equipment to carry out a process. This needs a good understanding of the various processes occurring in the system. The operation of the equipment under varying operating conditions must be analyzed since any process is prone to disturbances. This needs a model which captures all interactions. Such a model can be used for nonlinear analysis and to subsequently develop control strategies and optimize plant operation. The steady state and dynamic behavior is predi ....etc

Although grinding is considered one of the more established manufacturing processes, it is still relatively poorly understood. In particular, the interaction of the wheel with the workpiece at times seems more like an art than a science. In this presentation, a 3-D topographic measurement approach which encompasses both the wheel and the workpiece will be presented. The topographic information obtained from the wheel will be applied to a model to predict the workpiece surface generated which will then be verified by experimentation. The prelimi ....etc

A Paper Presentation on Software Development Automation by Computer Aided Software Engineering (CASE)



Abstract: Nowadays, system developers are faced to produce complex, high quality software to support the demand for new and revised computer applications. This challenge is complicated by strict resource constraints, forcing management to deploy new technologies, methods and procedures to manage this increasingly complex environment. Often the methods, procedures and technologies ar ....etc

Definition

The Unified Modeling Language (UML) is a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems. The UML represents a collection of best engineering practices that have proven successful in the modeling of large and complex systems. The UML is a very important part of developing object oriented software and the software development process. The UML uses mostly graphical notations to express the design of softwar ....etc
