This paper presents simulation results comparing Extrapolating Gain-Constrained Neural Networks (EGCN) to traditional neural network training methods, as well as to the recently proposed Bounded-Derivative Network (BDN).
The Mu-4000 Security Analyzer has emerged to help QA integrate optimized negative testing without impacting productivity. It delivers metrics related to service availability and security, resulting in the vendor knowing it is shipping higher quality products.
The industrialized world relies on a broad spectrum of vital critical infrastructure sectors. In addition to physical safety and security, network security for critical infrastructure is crucial because of reliance on electronic systems for operational control.
Manufacturers of level measurement technologies are often asked to recommend a technology for measuring bulk solids in vessels. Understanding the technologies available is an advantage when searching for an answer to the question of what to do.
The objective of this white paper is to educate the reader on the selection of point level monitoring technologies for specific applications to improve process efficiency, reduce up-front costs and minimize overall cost of ownership.
This white paper will cover display technologies, indicate which is best for industrial applications, discuss market and technology trends, and finally make recommendations about what to look for in a display.
This whitepaper is the first in a series on the security of OPC (OLE for Process Control) and focuses on providing an overview of the widely-used industrial communication standard and how it is actually used in industry.

This paper presents the results of tests conducted on ways of reducing the four types of noise encountered in electronic instrument circuits.
The use of computers and other sensitive electronic equipment in process instrumentation systems has demanded that more attention be give to electrical noise pickup in instrument circuits.
The superior performance of aluminum-Mylar tape shields in comparison with copper braid and copper served wire shields for static noise rejection is described.
The effect of twisting wires to cancel magnetic noise is compared to various shielding materials. Twisting the wires is shown to be the most effective practical way of reducing magnetic noise.
The control of common mode noise by the proper grounding of shields in thermocouple circuits is shown. The use of single grounding points in shield circuits grounded at the couple is recommended. Multipair cables with individual isolated pair shields are recommended.
Comparative results on cross talk elimination in multipair cables are presented. Individually shielded pairs are recommended as the most practical means of cross talk rejection in instrument circuits.

This paper discusses the scope and approach taken to integrate quality information from various analytical devices through a Laboratory Information Management System (LIMS) with a real-time process information system information connected to a distributed control system (DCS).
Digital fieldbuses are often justified on the basis of the benefits of advanced diagnostics. This paper investigates alternative technologies to capture diagnostics, without replacement of any field devices. The alternative method is field-proven and costs a fraction of the cost of fieldbus.
This paper summarizes key aspects of WirelessHART, including several of the design decisions that make it the right choice for wireless process automation. More detailed information is available at www.hartcomm.org.
