Title: "Robust Disturbance Observer Design Using Semi-Definite Programming"
Disturbance observers (DOBs) are important add-on schemes for disturbance rejection in feedback loop systems leading to robust performance. This presentation is concerned with optimal synthesis of disturbance observers guaranteeing closed loop robust tracking and disturbance rejection performance. The approach presented makes use of internal model-based estimation of exogenous disturbances, where the internal model dynamics is chosen with at least one of its eigenvalues at the origin. The synthesis is then formulated as an H-infinity weighted-sensitivity optimization for static output feedback (SOF) gain of a Luenberger observer. A linearization method is then implemented to solve the bilinear-matrix-inequality (BMI) constrained semi-definite program (SDP) for a (sub)optimal static gain.
Was Born in Cairo, Egypt in 1975. H received a BSc in mechanical engineering from the American University in Cairo in 1998. In the following 2 years he worked as a controls engineer in Egypt. In 2000 he obtained a MSc in control theory from the University of Sheffield, UK specializing in nonlinear optimal control. In the subsequent years he joined UC Berkeley, where he obtained PhD in control systems from the mechanical engineering in 2008 and MA in mathematics in 2007. His research interests lie in optimization techniques for robust control and estimation of uncertain systems, nonlinear control systems and advanced mechtronics applications. His recent work focuses on control applications in energy efficient systems, energy harvesting and wind turbines. Dr. El-Shaer has published a number of conference and journal papers on control systems

Title: "Joining Dissimilar Materials: Liquid-Phase Bonding of Ceramics"
Abstract: Complex engineering designs often require the use of dissimilar materials. Joining ceramics toother components is difficult to perform without limiting the potential of the material. The success of Partial-Transient-Liquid Phase (PTLP) joining of alumina is presented. This method is shown to rapidly produce mechanically sound joints without limiting the thermal capabilities of the ceramic
Bio: Prof. Bartlow is a lecturer at Santa Clara University in the Mechanical Engineering Department as well as in the Materials Science Department at U.C. Berkeley. He has earned his Ph.D. from U.C. Berkeley last Ma for research on the effects of surface roughness on liquid-phase joining of ceramics.

Mr. Craig Bauling, Wolfram Research
Seminar in Santa Clara University School of Engineering Design Center, Tuesday October 26, 2010
Learn the capabilities and practical applications of Mathematica 7 in this short seminar. Mathematica is a comprehensive technical computational software used by engineers, mathematicians, scientists, and other professionals. Mathematica allows users to compute, model, simulate, visualize, and document almost anything. Mathematica has been built and perfected to become the ultimate technical application and environment. In this seminar, Craig Bauling of Worlfram Research will highlight the impact of Mathematica on education and research, discussing a wide variety of practical and theoretical applications. Attendees will come away with a comprehensive understanding of Mathematica's key capabilities and core design principles. Prior knowledge of Mathematica is not required -new users are encouraged to attend. Current users will benefit from seeing the many improvements and new features of Mathematica 7.
“Multibody Dynamics Simulation using MSC Adams”
Mr. Walt Daniel, MSC Software, Austin, TX
Webcast live on location from Santa Clara University,
Saturday, September 25, 2010
Learn the basics of dynamic systems simulation with an overview of industrial applications, multiple Adams demonstrations, and three hands-on Training Segments (you build the model, analyze, and post-process with Adams on your system using the detailed instructions; bring your computer with Adams installed for the Hands-On Segments*). Adams is a widely used multibody dynamics simulation software package. With Adams, engineers can perform system-level analysis to evaluate and manage the complex interactions between disciplines including motion, structures and controls. This enables engineers to understand the dynamics of moving parts, how loads & forces are distributed throughout mechanical systems, and to optimize product designs for performance, safety, & comfort.
Control systems may be linked with the Adams model.
5.5 Professional Development Hours available.
