May 18th, 2005 speaker was: Bruce R. Montague
Topic: "Elements of Operating System and Internet History: A BSD Perspective"
E2-280 at 1pm.
Abstract:
This talk is an introduction to how operating
systems and networks came to be the way they are
today. This is done primarily by examining elements
in the technical history of the BSD family of operating
systems, while also considering some developments
in software licensing, government policy, open source
software, and the origins of commercial operating
systems and the Internet. While accessible to all,
this talk should be of special interest to system
programmers and system software researchers who are
unfamiliar with the historical development of the
field.
Biography of the Speaker:

the University of California, Santa Cruz.
Topic: "Computer Vision Applications for the Visually Impaired"
E2-215 at noon.
Abstract:
Living without vision is challenging. Simple tasks such as walking to
places, reading signs, orienting oneself and finding objects may become
overwhelming for a blind individual. Computer vision algorithms,
originally designed for robot guidance, hold the promise to enable
tools that can help visually impaired individuals in their daily life.
In this talk I will present an overview of computer vision-based
assistive technology approaches developed in recent year at UCSC and
elsewhere.

February 09th, 2005 speaker was:
Andrea Di Blas, CE Dept., UCSC
After a loss of interest in SIMD architectures until a few years ago, big
players in the computer architecture field are now looking with renewed
interest at vector and SIMD accelerators. This talk will introduce the
UCSC Kestrel SIMD parallel processor, its architecture and its
performance. Entirely designed and built by Prof. Hughey's group at UCSC,
this machine originally designed for computational biology has proven very
effective in a number of different applications. This 10-year-old
accellerator was so ahead of its time that it can still outperform
state-of-the-art CPUs clocked 50 times faster and higher, on some
problems. The group is currently finishing the design and test of the
next-generation model, Kestrel2, that will be mentioned too.
Biography of the Speaker:
Andrea Di Blas received his M.S. and Ph.D. degrees in Electrical
Engineering from Politecnico di Torino, Italy, in 1994 and 2000. He has
been a researcher at University of California, Santa Cruz, since 1999,
where he is also a lecturer with the Department of Computer Engineering.
His research interests include parallel processing methodologies and
applications, computer architecture, image processing, and combinatorial
optimization. He is a member of the IEEE Computer Society.
Software evolution is the study of how software projects change over a multi-year project
lifetime.
The widescale adoption of software configuration management technology over the 1990's has
resulted
in multiple commercial and open-source systems with long-duration records of the fine-grain
changes
made to software files. The existence of this data raises the opportunity to mine software
configuration management repository data for empirical data concerning software evolution.
Multiple
problems arise in analysing such data, including the reconstruction of checkin and merge
operations,
and how to extract and represent mined software facts. Kenyon is an infrastructure developed
at UCSC
for automating the extraction of facts over the revision history of software project. The
talk
presents an overview of issues in software evolution research, and the Kenyon repository.
Biography of the Speaker:
Jim Whitehead is an assistant professor in the Dept. of Computer Science at UCSC. His
research
interests include software evolution, software configuration management, remote
collaborative
authoring, and application layer protocol development.

WHERE: E2-280
Topic:"Distributed Optimization-Based Control of Multiagent Systems"
Abstract:
Multiagent systems arise in several domains of engineering. Examples
include arrays of sensor networks for aggregate imagery, autonomous
highways, and formations of unmanned aerial vehicles. In these contexts,
the individual subsystems are governed by decoupled dynamics and the
control
objective is achieved by cooperation. Cooperation refers to the
agreement of the subsystems to 1) have a common objective with
neighboring subsystems, with the objective typically decided off-line,
and 2) share information on-line to realize the objective. To be viable,
the control approach for these types of systems should be distributed,
rather than centralized. This is particularly true when the scale of the
overall system is large. Optimization-based techniques are suited to
multiagent problems, in that such techniques can admit very general
objectives. Receding horizon control is an optimization-based approach
that is applicable when dynamics are present. Researchers have
recently explored the use of receding horizon control to achieve
multi-vehicle objectives. In most cases, the common objective is
formulated, and the resulting control law implemented, in a centralized
way. In this talk, a means of distributing the receding horizon control
law is outlined. The resulting control law is provably asymptotically
stabilizing, as well as scalable. The example of multi-vehicle formation
stabilization will be used as a venue for the theory. The talk is
concluded by previewing recent results demonstrating that the same distributed
algorithm applies and is convergent when subsystems are dynamically coupled, as
is the case in process control.
Biography of the Speaker:
Prof. William B. Dunbar earned a PhD in the Control and Dynamical
Systems department at Caltech in April, 2004. His research
interests include control problems in large-scale networked
environments, consistent numerical methods in optimal control, and
connections between control theory and communication
theory. His dissertation gives a systematic and verifiable
approach for distributing a centralized optimization-based control
technique that has application in several domains of engineering,
including process control and robotics.
Topic:"Survey of Research in Wireless Signal Processing and Networking Laboratory"
Abstract:
Driven by the need to communicate anytime and anywhere,the field of wireless
communications has experienced tremendous growth in the past decade with the
proliferation of mobile telephones and wireless-enabled portable devices.
Large-scale deployments of packet-switched wireless local area networks
(WLANs) and third-generation cellular systems are taking place at a rapid
pace. Wireless networks are evolving from voice-centric services towards
mobile multimedia services. Many new services such as video-on-demand,
mobile workforce applications, voice over Internet Protocol and telemedicine
depend on the higher throughputs and reliability of next-generation wireless
networks. This talk presents a survey of advanced signal processing,
communications and networking techniques for the realization of these new
wireless applications.
