Description:
Algebraic topology is a basic part of modern mathematics, and some knowledge of this area is indispensable for any advanced work relating to geometry, including topology itself, differential geometry, algebraic geometry, and Lie groups. This book provides a detailed treatment of algebraic topology both for teachers of the subject and for advanced graduate students in mathematics either specializing in this area or continuing on to other fields

Saturday, August 15th, 2009In this paper the application of a crystal plasticity model for body centered cubic crystals in the simulation of an sheet metal forming process is discussed.The material model parameters are identified by a combination of a texture approximation procedure and a conventional parameter identification scheme.In the application of a cup drawing process the model shows an improvement of the strain and earing prediction as well as the qualitative spring back results in comparison with a conventional phenomenological model

Adaptive Control: Stability, Convergence, and Robustness
Monday, July 20th, 2009Number of pages: 378
Description:The objective of this book is to give the major results, techniques of analysis and new directions of research in adaptive systems. The authors give a clear, conceptual presentation of adaptive methods, to enable a critical evaluation of these techniques and suggest avenues of further development. The book presents deterministic theory of identification and adaptive control. The focus is on linear, continuous time, single-input single output systems.

Shielded Metal Arc Welding Guidelines
Monday, April 20th, 2009Shielded Metal Arc Welding (SMAW) or Stick welding is a process which melts and joins metals by heating them with an arc between a coated metal electrode and the workpiece. The electrode outer coating, called flux, assists in creating the arc and provides the shielding gas and slag covering to protect the weld from contamination. The electrode core provides most of the weld filler metal
The power in a welding circuit is measured in voltage and current. The voltage (Volts) is governed by the arc length between the electrode and the workpiece and is influenced by electrode diameter. Current is a more practical measure of the power in a weld circuit and is measured in amperes (Amps).
Submerged Arc Welding
Monday, April 20th, 2009A Submerged Arc Welding (SAW) option that combined the advantages of AC and DC Submerged Arc Welding was not possible until now.A high speed one-side submerged arc welding process of welding speed up to 1.5m/ min (16mm) has been developed for shipping of double-hull VLCC. In the new process, welding wires and fluxes as same as for a ordinary process are used. Electrode numbers are increased from three to four. Leading two electrodes fuse a root of a groove and form a underside (uranami) bead. Trailing two electrodes shape a good surface appearance bead and penetration. In case of 16mm thickness plate, total 3,000A welding current of leading two electrodes and total 1,500A of trailing electrodes are necessary to obtain good one-side weld. The new system has been practically applied to block assembly lines

Sieve Plate Tower
Sunday, April 19th, 2009Design a distillation column to separate ethylene oxide from ethylene
oxide water system. In this system a small amount of ethylene and traces of
acetaldehyde and formaldehyde are present. Comparing with the quantities
of the ethylene oxide and water present in the system, the amount of
ethylene and others are negligible. So it is considered as a binary system.
The distillation column operates at a pressure of 1 atmosphere pressure
(absolute). The feed entering is a mixture of 193.18 Kg moles of water,
95.133 Kg moles of ethylene oxide. The distillate is 99.9-mole % pure
ethylene oxide and the residue will contain 0.1 mole % ethylene oxide.

Oil Circuit Breakers
Sunday, April 19th, 2009Oil circuit breakers (OCBs) can be a real challenge for thermographers as they are an indirect measurement. Small temperature rises on the outside surface seen by the infrared camera, also known as a thermal imager can represent large temperature rises internally. This means great care must be taken, as a good understanding of surface emissivity and background temperature can be crucial when dealing with temperature rises of a few degrees C. Fortunately, most OCBs are painted with a matte finish, nonmetallic paint and have relatively high emissivities,
approaching 0.95.
This paper presents some OCB thermography data and examines problem severity using the watt loss calculation software developed by Dr. Madding and presented at InfraMation 2001. Post mortem photos of an OCB’s internals also lend strong validation to the calculation and the calculation software.
Using the calculation software is outlined and the procedures discussed, such as geometrical, thermographic and load measurements. Sample calculations are given to show the sensitivity of an OCB’s surface temperature rise to internal electrical resistance and other parameters. As a matter of further interest we add a lightning arrester power loss calculation.
Keywords: Infrared thermography, lightning arrester, heat transfer, convection, radiation, oil circuit breakers, watt
loss, power loss, internal electrical resistance, thermal balance, condition based maintenance, predictive
maintenance.
