A Systems Approach to Large-Scale Molecular and Nanoelectronic Memory & Logic Circuits
Mon, Oct 09, 2006 @ 12:00 PM - 01:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Prof. James Heath, CaltechAbstract: If the projections from the International Technology Roadmap for Semiconductors (ITRS) hold, then by the year 2020 it is expected that the most closely spaced metallic wires within a DRAM circuit will be patterned at a pitch of about 30 nm, implying that the conductors themselves will be of a width of around 15 nm. However, virtually every aspect of achieving this technology is considered to be 'red,' meaning that there is no known solution. Several years ago we began working on developing the architectures, devices, molecules, circuitry, and manufacturing processes for testing the limits of how far electronics circuitry could be scaled, with the basic presumption that any solution would require a combination of passive and active molecular components, semiconductor and metallic nanowires, and defect-tolerant architectures and manufacturing. In this talk, I will present results in which we have constructed large scale circuitry (> 10^5 devices) at densities that span the ITRS projections between the years 2020 and 2030. This will include a 160,000 bit memory circuit that is no larger than a white blood cell, demultiplexing circuits for such memories, and high-performance, ultra-dense logic circuitry that is energy efficient, exhibits gain, and constitutes a complete logic set. I will also discuss the molecular components and how we have learned, through thermodynamic and kinetic measurements of their switching processes, to optimize their performance within these extreme settings.Host: Prof. Daniel Lidar, lidar@usc.edu

Energy-efficient Transmissions with Delay Constraints over a Wireless Link
Tue, Oct 10, 2006 @ 03:30 PM - 04:30 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
SPEAKER: Mr. Wanshi Chen, Graduate Student, Communication Sciences InstituteABSTRACT: Future wireless networks are anticipated to accommodate diverse applications of various quality-of-service (QoS) requirements with limited system resource. There exists a fundamental trade-off between transmission energy and packet delay. It is of great importance to minimize the total packet transmission energy while satisfying the underlying delay constraints for network life maximization, system throughput maximization, etc. The problem of optimal offline scheduling (vis-a-vis total transmission energy) for a group of packets, each of which is subject to an individual delay constraint, over a fading channel is studied. The offline scheduler, assuming information of all packet arrivals and channel states before scheduling, is formulated as a convex optimization problem with linear constraints. The optimality conditions are analyzed. The properties of the transmission rates under the optimal offline scheduling and the corresponding delay performance are characterized. It is found that when packet sizes and channel coefficients are identically and independently distributed, the optimal transmission rates exhibit a symmetry property. The properties of the optimal offline scheduling and the impact of packet sizes, individual delay constraints, and channel variations are demonstrated via simulations. A heuristic online scheduling algorithm, which utilizes both causal traffic and channel variations, is proposed and compared with the optimal offline scheduling in terms of delay and energy performance via simulations.BIO: Wanshi Chen received a B.S. degree (with highest honors) from Southwest Jiaotong University, Chengdu, China and an M.S. degree from the Ohio State University, Columbus, respectively.

"ISAR Image Reconstruction Technique with Stepped Frequency Moducation and Multiple Receivers"Prof. Andon LazarovBurgas Free UniversityBulgariaAbstract:A new three-dimensional (3-D) model of deterministic components of ISAR trajectory signals with stepped frequency modulation is suggested. 3-D ISAR geometry is described by means of analytical geometry. The geometry and kinematics of the object and ISAR observation system are described in separate 3-D Cartesian coordinate system. The object space, moving rectilinearly, is presented as a 3-D regular grid of isotropic point scatterers. The analytical expressions for computing the range distance to point scatterers of the object space are derived. The complex ISAR signal, reflected from the 3-D target is obtained by four receivers, placed on the axes and origin of the coordinate system of observation. Four 2-D ISAR signals, registered by receivers appear to be four 2-D projections of the 3-D ISAR signal. The 3-D image is considered as a set of 2-D images retrieved from the 2-D ISAR signal projections. The image reconstruction procedure includes both range and azimuth compression. Fast Fourier transforms are applied to each 2-D ISAR signal projection to realize range compression and discrete Joint time-frequency transform for azimuth compression. An autofocusing technique is applied to each received ISAR signal projection. To illustrate the capability of the 3-D ISAR signal mode, numerical experiment were caried out.Bio:ANDON DIMITROV LAZAROV received his M.S. degree in 1972 from the Electrotechnical State University-Saint Petersburg, Russia, in electronical engineering, his PhD degree in 1978 from Minsk Air-Defence Military Academy, Belarus and the D.Sc.

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
B.M. Mohan
Dept. of Electrical Engineering
Indian Institute of TechnologyAbstract:Input-output relationships of linear PI / PD / PID controllers are well known to the control community. In this seminar, input-output relationships of some fuzzy two-term (PI or PD) controllers, their classification, their properties, and their suitability (or unsuitability) for control application will be addressed. As a matter of fact, input-output relationship of a fuzzy two-term controller is not unique as it depends on contributing factors like nature of fuzzy sets, nature of control rules, type of fuzzy AND and OR operators, type of inference method, and type of defuzzification method. So, depending on the nature of contributing factors, different fuzzy two-term controllers are possible. It is very important to note that not all these fuzzy controllers are suitable for control. In order to decide about their suitability for control application, these controllers are analyzed and their characteristic behaviors are studied.Bio:B. M. Mohan was born in Tapeswaram, India in 1960. He received the Bachelors degree in Electrical Engineering from Osmania University in 1982, the Masters degree in Electrical Engineering (with Control Systems specialization) from Andhra University in 1985, and the Doctoral degree in Engineering from Indian Institute of Technology, Kharagpur, 1989.

Operating Point for MIMO Multiple Access Channel with Delay Sensitive Bursty Traffic
Fri, Oct 20, 2006 @ 11:30 AM - 12:30 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
SPEAKER: Professor Tara Javidi, UC San DiegoAbstract: Multiple antennas at the transmitters and receivers in a multiple access channel (MAC) can provide simultaneous diversity, spatial multiplexing, and space-division multiple access gains. The fundamental tradeoff in the asymptotically large SNR regime is shown by Tse et al (2004). On the other hand, MAC scheduling can provide a statistical multiplexing gain to improve the delay performance as shown by Bertsimas et al (1998).In this talk, we provide a combined analysis in an attempt to unify the gains provided by a MIMO MAC. In partiucalr, we formulate and analytically derive an order optimal operating point for MIMO-MAC channel for bursty sources with delay constraints. Our system model brings together the four types of gains: diversity, spatial multiplexing, space-division multiple-access provided at the PHY layer, and statistical multiplexing gains at the MAC scheduler. Our objective is to minimize the end-to-end performance as defined by the delay bound violation probability as well as the channel decoding error probability. We first find the order optimal diversity gain for a point-point MIMO communication and then extend the result to the case of MAC. Considering a MIMO MAC with CSI at the receiver, we find the optimal diversity gain and rate region in which the system should operate. In this, we arrive at an interesting interplay between the intensity of the traffic and resource pooling with regard to both multiple-access and statistical multiplexing gains.Bio: Tara Javidi studied electrical engineering at Sharif University of Technology, Tehran, Iran from 1992 to 1996.

Correcting quantum error with entanglement

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Mr. Min-Hsiu Hsieh, Communication Sciences Institute, USCAbstract: We show how entanglement shared between encoder and decoder can simplify the theory of quantum error correction. The entanglement-assisted quantum codes we describe do not require the dual-containing constraint necessary for standard quantum error correcting codes, thus allowing us to "quantize" all of classical linear coding theory. In particular, efficient modern classical codes that attain the Shannon capacity can be made into entanglement-assisted quantum codes attaining the hashing bound (closely related to the quantum capacity). For systems without large amounts of shared entanglement, these codes can also be used as catalytic codes, in which a small amount of initial entanglement enables quantum communication.Bio: Min-Hsiu Hsieh received his B.S. and M.S. degree from National Taiwan University, Taiwan.
