Micro-Electro-Mechanical Systems, or MEMS, are integrated micro devices or systems combining electrical and mechanical components. They are fabricated using integrated circuit (IC) batch processing techniques and can range in size from micrometers to millimeters. These systems can sense, control and actuate on the micro scale, and function individually or in arrays to generate effects on the ma...

In this paper recent semi-batch chromium sludge processing is compared with batch processing by simulation means mainly. A possible time and/or power consumption reduction using these two techniques is monitored to optimize the process. The process itself is strongly exothermic so the temperature control is necessary to keep the temperature under critical temperature point.

Curators of large aquaria where there is no significant primary production and water changes are impractical have been using biological denitrification to control high nitrate concentrations. The two denitrification systems described in this study operate in different ways: the Living Seas uses a batch system, while the New Jersey State Aquarium uses a flow-through system. The rate of denitrifi...

Loading data is one of the most critical operations in any data warehouse, yet it is also the most neglected by the database vendors. Data must be loaded into a warehouse in a fixed batch window, typically overnight. During this period, we need to take maximum advantage of the machine resources to load data as efficiently as possible. A data warehouse can be on line for up to 20 hours of a day,...

A new concept referred to as the batch roundness is presented in this paper. This concept is derived to illustrate the worst possible form error for a batch of circular features machined under the same conditions. It is to be used as a statistical quality measure for such a batch of circular features and evaluated by analyzing their systematic and random form error components. The definition of...

In Batch Steganography we assume that a Steganographer has to choose how to allocate a fixed amount of data between a large number of covers. Given the existence of a steganalysis method for individual objects (satisfying certain assumptions) we assume that a Warden attempts to detect the payload by pooling the evidence from all the objects. This paper works out the details of a particular meth...

The separation of a binary homogeneous azeotropic mixture using pressure swing distillation will be analysed on the example of acetonitrile/water. Two different processes are considered: the continuous heatand mass-integrated process and the inverted batch process. For both processes a model is developed and experimental data are given. In the paper the potential of the pressure swing distillat...

We propose a method for dynamic batch mode active learning where the batch size and selection criteria are integrated into a single formulation.
