Network Inference using Network Coding Techniques

CENG SEMINAR SERIES"Network Inference using Network Coding Techniques"Dr. Athina MarkopoulouUniversity of California, IrvineAbstract:Monitoring is an important component in the operation of any network. We are particularly interested in a family of monitoring techniques, known as network tomography, which aim at inferring internal network characteristics by sending and collecting probe packets from the edge of the network. Prior work on network tomography considered networks that implement multicast and unicast forwarding. Independently, the network coding community advocates that additional functionality should be added to network nodes, to allow for processing of incoming packets before forwarding them. This functionality comes at the cost of additional processing but also brings the potential of significant performance benefits. In this work, we consider networks where internal nodes implement network coding and we re-visit two network tomography problems: (i) link loss inference and (ii) topology inference. We develop new techniques that make use of the network coding capabilities and we show that they improve several aspects of the inference problem (including identifiability of links, accuracy of estimation, and complexity of probe path selection) over traditional techniques. Our rationale is that if network coding is to be deployed in some networks, e.g. to bring throughput benefits, then one can exploit this opportunity to also boost the performance of other operations, such as monitoring. This is joint work with Christina Fragouli and Suhas Diggavi from EPFL, Lausanne.Bio:Athina Markopoulou is an assistant professor with the EECS Dept, UC Irvine.

NONLINEAR ANALYSIS OF COMPOSITE AND FUNCTIONALLY GRADED SHELL STRUCTURES

JOINT SEMINAR FOR AME & CIVIL ENGINEERINGSPEAKER: J. N. Reddy,

jnreddy@tamu.eduABSTRACT
A tensor-based finite element formulation for the nonlinear analysis of laminated shell structures and through-thickness functionally graded shells will be discussed. A tensor-based finite element formulation is used to describe the deformation and 3-D constitutive laws of a shell in a natural and simple way by using curvilinear coordinates. In addition, a family of high-order elements with Lagrangian interpolations is used to avoid membrane and shear locking. A first-order shell theory with seven parameters is derived with exact nonlinear deformations and under the framework of the Lagrangian description. This approach takes into account thickness changes and, therefore, 3D constitutive equations are utilized. Numerical comparisons of the present results with those found in the literature for typical benchmark problems involving isotropic and laminated composite plates and shells as well as functionally graded plates and shells are found to be excellent and show the validity of the developed finite element model. Moreover, the simplicity of this approach makes it attractive for applications in contact mechanics and damage propagation in shells. A number of examples of applications to laminated composite shell structures are presented.Keywords: Finite element model, nonlinear shell theory, multilayered composites, functionally graded shells, numerical examples.Acknowledgement.

Earthquake Damage Detection in Two Buildings.....

Earthquake Damage Detection in Two Buildings - Comparative Analysis of Several Structural Health Monitoring Methods Including a New Wave MethodSpeaker: Dr. Maria Todorovska,
Department of Civil and Environmental Engineering,
USCAbstract:The only true validation of real time structural health monitoring methods is in terms of sensory data recorded in instrumented structures during a damaging event. For civil structures, damaging events are e.g. earthquakes, explosions, blasts, etc. Due to the high cost of instrumentation and the low frequency of occurrence of such events, data in damaged civil structures are rare, but do exist, e.g. vibrational data recorded in buildings by seismic monitoring arrays during a damaging earthquake. Yet, the existing data are rarely used, and methods are usually tested only on numerically simulated data of response with postulated damage and assumed additive Gaussian noise. Results will be presented of a critical comparative analysis of several structural health monitoring methods applied to detecting damage in two instrumented buildings th the 1971 San Fernando and 1994 Northridge earthquakes, and for which records of 10 other earthquakes are also available.The first method is a new method, based on measuring wave travel times through the building using impulse response functions, applied to structural health monitoring for the first time in the presented work. This method is more reliable than monitoring changes in the apparent building frequencies, which are sensitive to the effects of soil-structure interaction and environmental factors, such as weather. Further, it is local and can detect the location of damage with relatively few sensors as compared to the methods based on detecting changes in curvature of the mode shapes of vibration, which require extensive instrumentation. Another relatively new method is based on detecting novelties in the recorded response using wavelets, previously tested on numerically simulated data but not conclusively on real data. This method is superior to all other methods in its resolution of the estimate of the time of the occurrence of damage. The analysis of this method also revealed that the noise in this method, consisting of high frequency pulses from the ground motion traveling through the building, contains useful information about the travel times through the building, and hence can also be used to infer about the changes of the state of health of the structure. The results by these two methods are compared with the distribution and degree of the observed damage, and with results of analyses based on other indicators of damage, such inter-story (dynamic) drifts estimated from the recorded accelerations, observed changes of the "instantaneous" apparent frequencies of vibration as functions of the amplitudes of response, estimated from the ridges and skeletons of the Gabor transform, and finally by analysis of simulated response using ETABS. The mutual consistency of the results by different analyses methods, and their consistency with the observed damage are discussed and several important conclusions are drawn.Location: KLaprielian Hall 203

Models for Improving Mass Dispensing and Vaccination Clinic Planning
Wed, Feb 28, 2007 @ 03:30 PM

University Calendar
EPSTEIN ISE DEPARTMENT SEMINAR - "Models for Improving Mass Dispensing and Vaccination Clinic Planning"Jeffrey W. HerrmannAssociate Professor, Department of Mechanical Engineering and the Institute for Systems Research,
Director, Computer Integrated Manufacturing Laboratory, University of MarylandABSTRACT: To prepare for a biological attack or epidemic, public health departments must plan mass dispensing and vaccination clinics (MDVCs). This talk discusses simulation models and queueing network approximations being used to improve MDVC planning. Based on key clinic parameters, the models estimate clinic capacity and the time patients spend in the clinic. Clinic capacity affects the number of clinics that must be opened and the total time needed to vaccinate the affected population. The time-in-system affects the number of patients who are inside the clinic. More patients require more space and cause congestion, crowding, and confusion. To improve MDVC planning, researchers at the University of Maryland have been collaborating with public health professionals to develop appropriate models and implement them for use by emergency preparedness planners.The models determine not only the utilization of the staff in the clinic but also the average number of patients waiting in line at each station in the clinic and the average time that patients spend in the clinic. The presentation will also cover recommendations for clinic layout to improve patient flow.WEDNESDAY, FEBRUARY 28, 2007, ANDRUS GERONTOLOGY BLDG, GER 309, 3:30-4:50 PM******BIOGRAPHICAL SKETCH: Jeffrey W.

Aerospace and Mechanical Engineering
Conferences, Lectures, & Seminars
ANTHONY S. WEXLERDepartment of Mechanical and Aeronautical EngineeringDepartment of Civil and Environmental EngineeringDepartment of Land, Air and Water ResourcesUniversity of California, DavisAbstract:USC faculty, staff and students have played a leading roll internationally in elucidating the physical and chemical constituents in the atmosphere and the health effects that they elicit. But like investigators everywhere, this work has been limited by the spatial resolution of the instruments that are available. Usually, a few measurements in a vast urban area such as Los Angeles must suffice due to instrument costs even though there are tremendous spatial inhomogeneities for many of the toxic pollutants. This talk will present a nascent effort at UC Davis to design and build an inexpensive, easily manufactured ion mobility spectrometer that is suitable for analyzing many common pollutants, especially the organic ones.Location: Seaver Science Library (SSL) Room 150
