Innovations in Metallurgical Manufacturing: From Concept to ImplementationPatricio F. Mendez
Assistant Professor
Department of Metallurgical and Materials Engineering
Colorado School of MinesABSTRACTMetal processing operations are governed by a number of physical principles, typically
many more than other manufacturing processes such as the assembly of parts, for
instance. This physical complexity is a double edge sword: it opens the door to radically
new ideas, but it makes their design and implementation very difficult. This presentation
will address this challenge from both points of view.
I will introduce a conceptual framework and new tools to address technical complexity;
we will see how scaling and similarity techniques can be extended to tackle the multicoupled
and often poorly defined problems in metals processing, using welding as an
example. I will also use some of these tools to analyze a radically new metallurgical
process very similar to Contour Crafting, and show how this analysis could be extended
beyond metals. Finally, I will describe de invention of a new die-casting process using
semi-solid metals, based on the alteration of existing processes. This process has
revolutionized the semi-solid industry, and it is currently being used to manufacture a
component of the Ford Focus.Location: Ethel Percy Andrus Gerontology Center (GER) - 309

Generalized ACE codes

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
SPEAKER: Mr. Aditya Ramamoorthy, EE Dept, UCLAABSTRACT: Low-Density Parity-Check Codes have been the subject of intense research lately because of their linear decoding complexity and near capacity achieving performance. Recent results show that LDPC codes drawn at random from irregular degree distribution ensembles can have significantly better performance asymptotically than regular LDPC codes and in fact provably achieve capacity over the binary erasure channel.At finite block lengths however one can achieve much better performance over randomly chosen codes by a careful construction of the parity check matrix. In this talk I shall explain the Approximate Cycle EMD (ACE) algorithm (Tian et al.) for the construction of LDPC codes for a given block length and degree distribution and discuss a generalization of their approach. I shall discuss the analysis of the expected stopping set spectrum of generalized ACE constrained ensembles which shows their improved performance over the binary erasure channel and the expansion properties of these codes that justifies their improved performance over the AWGN channel. Techniques for improving the performance even further at short block lengths will also be presented.This is joint work with Prof. Richard Wesel.BIO: Aditya Ramamoorthy is a Ph.D. candidate in the Electrical Engineering Department at the University of California, Los Angeles. He received his B. Tech. from the Indian Institute of Technology, Delhi in 1999 and his M.S. from UCLA in 2002. From 1999-2001 he was working as a systems engineer at Biomorphic VLSI Inc. In the summer of 2004 he was an intern at Microsoft Research working on network coding.His research interests include coding theory (in particular LDPC code design and analysis) and network coding.Host: Dr. Keith M.

THE IMPACT OF DIFFERENT ORGANIZATIONAL FORMS OF ROAD PUBLIC TRANSPORT ON DISTANCE COVERED AND ATMOSPHERIC POLLUTIONMarco DianaPost Doctoral Fellow
Institut National de Recherche sur les Transports et leur Sécurité (INRETS - The French National Institute for Transport and Safety Research)
Département Economie et Sociologie des Transports (DEST)ABSTRACTThe operation of public transport services that minimize emissions of pollutants plays a key role in improving air quality in urban areas. Considerable financial resources are employed to buy buses with innovative propulsive systems. However municipalities in poorer countries might not have sufficient funds to endow their fleets with such vehicles. We discuss the possibility of lowering distances traveled and associated emissions by changing the organizational form of the service. We consider a traditional bus service and a demand responsive service using buses or vans, and we identify the best system for every combination of demand and service quality with respect to travel and emissions minimization. The analysis is repeated for different urban patterns and street networks. Results indicate that the use of a demand responsive service can lower distances traveled when the demand is quite low, but that a good quality is required, provided that service requests are known in advance. Furthermore, the utilization of smaller vans with lower emission factors can deliver substantial benefits in terms of reducing atmospheric pollution, with an often negligible increase in kilometers traveled.BiosketchMarco Diana is a post doctoral fellow at INRETS, the French National Institute for Transport and Safety Research. He graduated in Civil Engineering at Turin Polytechnic (Italy), where he also took his Ph.D. in Transportation Engineering. He previously visited with USC's Epstein ISE Department for 7 months as a part of his Ph.D. research program. His research interests focus mainly on issues related to the ground implementation of unconventional public transportation modes, both on the supply (planning challenges) and on the demand side (users' behavioral reactions).

DISTINGUISHED LECTURER SERIES - DNA: Not Merely the Secret of Life, Prof. Nadrian Seeman, NYU

Abstract:========Our laboratory works in the area of structural DNA nanotechnology. We use the concept of reciprocal exchange between DNA double helices to produce branched DNA motifs, like Holliday junctions, or related structures, such as double crossover (DX), triple crossover (TX), paranemic crossover (PX) and DNA parallelogram motifs. We combine DNA motifs, using sticky-ended cohesion, to produce specific structures. The key strength of sticky-ended cohesion is that it produces predictable adhesion combined with known structure. We have constructed DNA stick-polyhedra, whose edges are double helices, and whose vertices are the branch points of DNA branched junctions. These include a cube, a truncated octahedron, and an irregular graph. Nanorobotics are key to the success of nanotechnology. We have used two DX molecules to construct a DNA nanomechanical device by linking them with a segment that can be switched between left-handed Z-DNA with right-handed B-DNA. PX DNA has been used to produce a robust sequence-dependent device that changes states by varied hybridization topology. The sequence-dependent nature of this device means that a variety of them attached to a motif can all be addressed individually. Recently, we have used this device to make a machine that does chemical translation. A central goal of DNA nanotechnology is the self-assembly of periodic matter. We have constructed micron-sized 2-dimensional DNA arrays from DX, TX, two kinds of parallelogram motifs. We can produce specific designed patterns visible in the AFM from DX and TX molecules. We can change the patterns by changing the components and by modification after assembly. Recently, we have used new motifs to produce honeycomb-shaped arrays. The key structural challenge in the area is the extension of the 2D results obtained so far to 3D systems with a high degree of ordering. Crystals with dimensions as large as a millimeter, ordered to 10 Å resolution (as determined by X-ray diffraction) have been produced. Ultimately, we expect to be able to produce high resolution crystals of DNA host lattices with heterologous guests, leading to well-ordered bio-macromolecular systems amenable to diffraction analysis. Other challenges are to incorporate DNA nanomechanical devices in periodic and aperiodic lattices and to use the lattices to organize nanoelectronic components, such as metallic nanoparticles or carbon nanotubes.Bio:===Nadrian C. Seeman was born in Chicago in 1945. Following a BS in biochemistry from the University of Chicago, he received his Ph.D. in biological crystallography from the University of Pittsburgh in 1970. His postdoctoral training, at Columbia and MIT, emphasized nucleic acid crystallography. He obtained his first independent position at SUNY/Albany, where his frustrations with the macromolecular crystallization experiment and his awareness of the fatal series--no crystals, no crystallography, no crystallographer--led him to the campus pub one day in the fall of 1980. There, he realized that the similarity between 6-arm DNA branched junctions and the flying fish in the periodic array of Escher's 'Depth' might lead to a rational approach to the organization of matter on the nanometer scale, particularly crystallization. Ever since, he has been trying to implement this approach and its spin-offs, such as nanorobotics and the organization of nanoelectronics; since 1988 he has worked at New York University. When told in the mid-1980's that he was doing nanotechnology, his response was similar to that of M. Jourdain, the title character of Moliere's Bourgeois Gentilehomme, who was delighted to discover that he had been speaking prose all his life.

Self-Reconfigurable Robots and Digital Hormones for Multifunctional Applications
Fri, Jan 28, 2005 @ 10:30 AM - 12:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Patrick Pantel hosts a talk by Dr. Wei-Min ShenSelf-reconfigurable modular robots are metamorphic systems that can autonomously change their logical or physical configurations (such as shapes, sizes, or formations), as well as their locomotion and manipulation, based on the mission and the environment in hand. Because of their modularity, versatility, self-healing ability and low cost reproducibility, such robots provide a flexible approach for achieving complex tasks in unstructured and dynamic environments. They are well suited for applications such as search and rescue, reconnaissance, self-assembly, inspections in hazardous environments, and exploration in space and ocean.The construction and control of these robots, however, are very challenging due to the dynamic topology of the module network, the limited resource of individual modules, the difficulties in global synchronization, the preclusion of centralized decision makers, and the unreliability of communication among modules. This talk presents the recent progress in our lab for these challenging tasks and their applications for affordable and sustainable space missions in the near future. Dr. Shen will present the hormone-inspired distributed control architecture and algorithms (US-patented), demonstrate with movies for the ability of plug-and-play and arbitrarily reshuffling modules (body-parts) in systems, discuss theoretical development for self-reconfigurable systems in general, analyze the hardware/software challenges in making such robots for real-world multifunctional applications, and outline current solutions for these challenging tasks. The talk will be interactive and feedback and discussions are most welcome.Bio:Dr. Wei-Min Shen is the director of Polymorphic Robotics Laboratory (http://www.isi.edu/robots) at USC/Information Sciences Institute (ISI), and has over 22 years of experience in research.
