Data Exchange in Geotechnical Engineering
Mon, Aug 09, 2010 @ 02:00 PM - 04:00 PM
Sonny Astani Department of Civil and Environmental Engineering
Conferences, Lectures, & Seminars
Oral Defense by: Nazila Mokarram, Ph.D. Candidate, Astani Department of Civil and Environmental Engineering, USCAbstract:Although geotechnical information is obtained from rather costly drilling and laboratory operations, they are poorly documented and curated, due to lack of adoptable standards for data handling. This study develops a requirement list for data exchange format based on the advantages and shortcomings of past efforts and the community specific needs. After careful analysis of geotechnical data, an XML-based data organization is proposed. Then the proposed format is used in examples of data generation and modification, data validation, data exchange, and archive and distribution via World Wide Web. To show the improvements of the new data exchange format over the previous formats, the proposed data format is evaluated by comparing its capabilities with the requirement list developed early in the study. At the end, metadata modeling is proposed as an added layer over data exchange for future work.

One of the most exciting breakthroughs in cell biology over the past decade is the recognition that micromechanical inputs to cells from the solid-state extracellular matrix (ECM), such as those encoded in ECM geometry, topography, and elasticity, can influence cell and tissue physiology and pathology in profound and specific ways. This connection between mechanics and biology (mechanobiology) bears direct relevance to the pathogenesis of diseases of the nervous system in which cells alter their structure, motility, or compliance, including neuronal and glial tumors and neurodegenerative disorders, and suggests that specific cell behaviors may be engineered by directly manipulating the underlying molecular systems. I will discuss efforts my colleagues and I have taken to harness the potential of mechanobiological crosstalk between cells and the ECM to understand and manipulate tumor and stem cell biology in the nervous system. I will describe studies in which we elucidate the role of physical cues from the ECM in driving cell structure, cytoskeletal organization, cell migration, and proliferation in malignant brain tumors. I will also discuss our efforts to engineer the differentiation trajectories of neural stem cells by manipulating the biophysical properties of the ECM and the mechanotransductive signaling pathways that enable cells to mechanically communicate with the ECM.Hosted by: Center for Applied Molecular Medicine.

Mobility Assisted Routing for Hybrid Ad Hoc Networks

Abstract: In hybrid ad hoc networks, most nodes are stationary, while only a few nodes move at a fast speed.
By exploiting the mobility assistance, the network performance, such as route quality and lifetime, can be
largely improved. Specially, a few fast moving nodes (FNs) collect last encounter information while they are
moving within the network. Whenever they encounter stationary nodes (SNs), they diffuse their last
encounter information to SNs. Based on the temporal-spatial correlation, both FNs and SNs can compute the
distance with other nodes, therefore the last encounter information can guide route search. Accordingly, we
develop one mobility assisted routing scheme for so-called hybrid ad hoc networks. The analytical model is
also addressed. Simulation results demonstrate that the route search cost is decreased significantly, and is
linear with the distance between source and destination nodes. Simulation results also illustrate the validation
of the analytical model. Moreover, our other related work will be briefly introduced, such as messenger
nodes based routing, mobility assisted clustering, mobility assisted service discovery, and mobility assisted
distributed certification.

"High Performance Packet Forwarding on Parallel Architectures"Thesis Abstract:
Packet forwarding has long been a performance bottleneck in Internet infrastructure including routers and switches. While the throughput requirements continue to grow, power dissipation has emerged as an additional critical concern. Also, as the Internet constantly evolves, packet forwarding engines need to be flexible to enable future innovations. Although ternary content addressable memories (TCAMs) have been widely used for packet forwarding, they have high power consumption and are inflexible for adapting to new addressing and
routing protocols.This thesis studies the use of low-power memory technology such as static random access memory (SRAM)
combined with field-programmable gate arrays (FPGAs) to develop high-throughput, power-efficient and
flexible solutions for various packet forwarding problems including IP lookup, packet classification and flexible flow matching.We propose an algorithm-architecture co-design framework to map state-of-the-art packet forwarding
algorithms onto SRAM-based parallel architectures. Several challenges for such mapping are addressed. High
throughput is achieved via pipelining or multi-processing. Meanwhile, enabled by the architecture design, the algorithms are optimized to reduce the memory requirements to fit large forwarding tables in the on-chip memory. In addition to the power reduction achieved by replacing TCAMs with SRAMs, we propose
architecture- and data structure -level optimizations to further lower the power consumption. We prototype our solutions on FPGA and demonstrate that they outperform the state-of-the-art with respect to throughput, memory requirement and power consumption.Defense Committee:

Talk Title: Controlled Susbstructure Identification for Shear Structures
Abstract:
Abstract:
Shear structure models are widely used to model the dynamics of building structures; therefore, developing the techniques, which can accurately identify the parameters of a shear structure, plays a vital role in establishing efficient and reliable structural health monitoring systems for building structures.
In this dissertation, applying the âdivide and conquerâ strategy of substructure identification (SI), a series of innovative SI methods for shear structure are developed. A shear structure is divided into many two-story standard substructures. An ingenious induction identification procedure is applied to identify the parameters of the whole structure from top to bottom inductively. Numerical simulation results verify that these substructure identification methods provide accurate identification results.
One of the most important features of these SI methods is that the analytical results of the identification error is obtained, which demonstrates that the identification accuracy is simply controlled by the structural responses near the substructure natural frequency. This important discovery provides the ability to easily improve the identification accuracy by accordingly changing the substructure responses via specially designed structural control systems. Several controlled substructure identification methods were proposed, using different structural control systems to improve the accuracy of the SI methods. Moreover, since the accuracy of the proposed controlled SI methods directly depends on the close-loop controlled structural responses rather than on the control systems themselves, these controlled SI methods are proved to be quite robust to possible control system errors.
To overcome the limitations of the previous SI methods, a loop substructure identification method is proposed which makes use of the dynamic equilibrium of only one standard substructure to formulate a loop identification sequence and identify all parameters of that substructure once for all. Compared with the previous SI methods, the loop SI method is able to perform the structural identification of any part of a shear structure with only three floor acceleration responses; more importantly, the loop substructure identification can be carried out with knowing the structural mass information.
Furthermore, a new approach is proposed to extend the SI methods originally developed for shear structures to more realistic but complex frame structures. The study shows that the proposed approach is able to accurately structural damage of columns in a frame structure
