Next Week is Engineers Week at UCSD



They say that everyday should be Mothers Day. Considering how crucial technology is for everything we do from communication and banking, to environmental sustainability and health care, everyday should also be Engineers Day. Nevertheless, next week is the one week out of the year that is carved out as National Engineers Week – and the students at UCSD’s Jacobs School of Engineering are taking part in a big way.

You can learn more about all the events at the Jacobs Schools Engineers Week site.

No More Database Design or Web Programming


Consider adding “no more database design or web programming” to your list of New Year’s resolutions. At DEMO 2008, UC San Diego startup App2you announced that it is opening itself up to the general public – initially for free. With app2you’s patented algorithms, you can whip up a customized interactive Web application in minutes without touching a line of code or thinking a single database-driven thought.

App2you’s key innovations come from a series of patented algorithms that perform the database design and programming for you.

“Users simply specify page design and decide who should have access to what information using our JustSketch tool. Our algorithms do the rest,” says Yannis Papakonstantinou, app2you founder and computer science professor from UC San Diego’s Jacobs School of Engineering.


App2you is one of the 16 startup companies nurtured since 2002 by the William J. von Liebig Center for Entrepreneurism and Technology Advancement at UCSD’s Jacobs School of Engineering. The von Liebig Center – recently recognized for excellence by the Ewing Marion Kauffman Foundation and the Max Planck Institute of Economics – awarded app2you critical seed funding through a competitive review process in 2006. The support enabled Papakonstantinou and his team of UCSD students to develop the technology to the point where they could attract the angel funding they needed to commercialize their algorithms.

Center for Networked Systems (CNS)




The Center for Networked Systems (CNS) at UCSD has a new brochure which you can check out online.


The scribblings on the whiteboard on the back page are related to professor Joe Pasquale's work on long-running replicated systems.

Amin Vahdat, a UCSD computer science professor is the current CNS Director. I have pasted his director's message below:

The last decade has been witness to exponential
growth in the speed and coverage of digital communication
networks. We are now at an inflection
point in the utility of the now global communication
network. Moving forward, the reach of the
network will enable a new class of applications
and opportunities to collaborate and communicate.
With these opportunities come a number of
challenges. As networked applications and
services permeate our daily experience, we will
require new techniques to improve the security of
our data and to manage scale and complexity of
the millions of compute and communication
elements powering the global network.

At UCSD’s Center for Networked Systems (CNS),
we have assembled a world-class team of faculty
and students, performing cutting-edge research in
all areas of computer networks, from optical
interconnects and wireless sensor networks to
data center architectures and network security.
Our faculty are internationally recognized leaders
with a reputation for working on practical, highimpact
problems, while simultaneously performing
fundamental research to advance the state of the
art. Our students are highly sought after, regularly
securing top industrial and academic positions.


A significant differentiator at CNS is our culture of
industrial partnership. By working closely with our
member companies to define research efforts of
mutual interest, we are able to engage the top
companies in our field to both understand the
important problems facing real deployed communication
systems and to jointly work toward solutions.


Our students typically enjoy the opportunity to either
begin or continue collaborative research as
a part of our very successful summer internship
program. On a number of occasions, summer
internships have led to dissertation topics and
even impacted company practices or products.
We believe the revolution in communication networks
is just beginning. With the strength of our
students, our faculty, and our deep collaborations
with our industrial partners, UCSD’s Center for
Networked Systems will continue to be at the
forefront of these exciting times.

Selective Scanning for Faster Prostate Pathology


In new work from the UCSD Jacobs School of Engineering and the UCSD Medical Center, computer vision and machine learning techniques are being used to create an automated system to analyze low magnification images of prostate tissue sections and select those parts of the specimen that should be scanned at high magnification for examination by human diagnosticians. Pathologists hardly ever view entire images at high resolution, but rather concentrate on a few relevant parts. The new system selects the parts that warrant scanning at high magnification.

The very large sizes of image files generated by digital microscopes with a scanning mechanism can make it hard for pathologists at different locations to consult with each other by sharing files through the Internet. The new approach can decrease the space required for storage and time for transmission by a factor of ten.

The new collaborative work from UCSD electrical engineering Ph.D. student Mayank Kabra, computer science professor Yoav Freund and UCSD Medical Center clinical pathology professor Steve Baird will be presented on Thursday 17 January 2008 at the Workshop on Bio-Image Informatics: Biological Imaging, Computer Vision and Data Mining, 2008, hosted by UC Santa Barbara’s Center for Bio-Image Informatics.

Two ECE Profs, Two Spin-Outs, Two Product-Award Nominations…Just One Award





Products from two different companies spun out by electrical engineers at UC San Diego are finalists for CONNECT’s 2007 Most Innovative New Product “MIP” Award – in the Communications Technology & Hardware category.

CONNECT is a globally recognized public benefits organization that fosters entrepreneurship in San Diego. The winning product will be announced at a December 14, 2007 award ceremony.

The two UCSD spin-out companies are Mushroom Networks, Inc., founded by Rene Cruz, and Ortiva Wireless founded by Sujit Dey – both of whom are electrical engineers at the Jacobs School.

Mushroom Networks was nominated for its Broadband Bonding Network Appliance and Ortiva Wireless for Ortiva Mobile Content Delivery Network.

Mushroom Networks’ Broadband Bonding Network Appliance provides cost-effective accelerated Internet connectivity to entities within multi-tenant buildings who wish to aggregate multiple Internet access lines for increased performance and reliability. With the Broadband Bonding Network Appliance, up to five DSL, cable modem or T1 services can be combined.

The Ortiva Wireless Mobile Content Delivery Network gives content providers and aggregators an innovative, hosted means of managing and delivering content to mobile subscribers. It delivers smooth video, clear audio, and rich multimedia experience to mobile users under highly variable wireless network conditions. Ortiva’s mobile network operator solutions extend the coverage and expand the availability of rich media content.

Rene Cruz, an electrical engineer from UCSD, founded Mushroom Networks in 2004 with Dr. Cahit Akin. Cruz currently serves as Chief Science Officer. Cruz works in the area of performance analysis of communication networks and has developed traffic and service models for communication networks that have been widely adopted within the research community. He is an internationally recognized expert in the area of Quality of Service (QoS) guarantees in packet switched networks, and was elected to be a Fellow of the IEEE on the basis of these accomplishments.

Sujit Dey, an electrical engineer from UCSD, founded Ortiva Wireless in 2004 based on technologies developed at the Jacobs School. Dey heads the Mobile Systems Design and Test Laboratory within the Department of Electrical and Computer Engineering at the Jacobs School. He has twenty years of experience in research, technology, and product development in wireless networks, wireless multimedia, systems, circuits, and design tools.

3D Reconstruction: UCSD's Latest Contribution


Augmented reality walkthroughs of a building or a city, online alignment of a camera network and 3D navigation through a collection of photographs are just a few of the potential applications of an algorithm created in the computer science department at UC San Diego's Jacobs School of Engineering.
For this work, UCSD computer scientists earned was one of three honorable mentions for the David Marr prize which is the best paper award at the world’s premier computer vision conferences, ICCV, the International Conference on Computer Vision which took place last month in Rio de Janeiro, Brazil.

“The algorithm is very much practical. We have performed real-life 3D reconstructions. In fact, the significance of the paper lies in our approaches for designing a theoretically correct algorithm that also works well in practice,” explained Manmohan Chandraker, the first author on the award-winning ICCV paper and a fifth-year Ph.D. student in the Department of Computer Science and Engineering at UCSD’s Jacobs School of Engineering.

A longer story on this research is still in the works. Check out this low-fidelity video that gives a taste of the research.
