Control
Topology Control: reduce overall power consumption and
interference while maintaining network connectivity.
• Conventional antennas are omnidirectional.
• Smart antennas focus the energy in one or
several desired directions:
Active
Beam
Desired
User
Antenna
Array
• Benefits
– Extended communication range
– Reduced interference
Antenna
Array
• New research problems!
– Medium Access Control Protocols
– Topology Control Methods
– Routing Protocols
• An integrated approach for all the above
• Goal: maximize the benefits of smart
antennas
• Modular robots composed of smaller unit
• Go from a source configuration to a target configuration without selfintersection.

How is it that five software engineering
teams, working independently for five
companies, ‘conspired’ to produce, in every
case, electronic voting devices that are
uniformly prone to malfunction and
vulnerable to malicious attack?
Is this a technology that we really need?
Or is it a solution to a non-existent problem?



Since 1998, we have maintained a collaboration
with students and teachers at Julia de Burgos
Elementary School in North Philadelphia
Designed to redress some of the obstacles to
learning new technologies affecting children from
low income neighborhoods
This involvement began with Lance Rougeux, a
1998 graduate and alumnus of my first Ethical
Issues class, who began his career as a 6th grade
teacher at Julia de Burgos


The 2005 team of Jessie Byrnes, Tom Huffner, Todd McNeal,
Lauren Pisciotta, and Zack Zweber presented a poster on their
project at ITiCSE 2006 in Bologna
The 2007-2008 “F”-team – Will Matthaeus, Kory Kirk, John
McCoey, Kate Breen, Mujtaba Talebi, George Frank, Paolo
Repole, Agya Adueni, Tom Homsher, Mike Topf, Andrew Burke,
and Alex Hanna – reprised the 2005 Life Expectancy Project
with six eighth grade classes at Julia de Burgos
In Fall 2008, the Villanova Student Chapter of ACM, Minh Kinh
Tran, Casey Burkhardt, John McCoey, A. J. Palkovic, with the
indispensable assistance of Najib Nadi, rehabilitated 12
laptops purchased from Team Children, and conducted a four
weekend course for 12 Julia de Burgos students
Also in 2008, Minh Kinh Tran, Casey Burkhardt, John McCoey
and Najib Nadi restored the JdB mobile computer labs to use



We’ve received 20 laptops from Villanova, as part
of the rollout of new equipment this past summer
We will repeat last year’s project in Spring 2010,
populating these computers with Open Source
software, and reprising the four weekend course
with 20 JdB students
If this collaborative effort interests you, just come
and talk to me…

Project Ideas
◦ Collecting and analyzing data related to the software development
process
◦ Report on the use of a new technology to create a system, perhaps
comparing it to use of a different technology
◦ Investigating the status of the “good guys” vs “bad guys” situation
in computer security
◦ Classifying “classes” based on the signatures of their methods ...
◦ What “types” of learners learn X best when approach Y is used

Can we use blogging in large lecture
sections?
Can Blogging be used to solicit opinions of
shy students?
Can Blogging make students aware of
controversial issues?
Do students feel freer to express themselves
using the computer?

Blogging has been effective in one Computer
Science class over multiple terms
◦ Students comment on the various effects of
technology, both current and future

This semester blogging will be introduced in
one Biology class
◦ “Should there be a Universal DNA database”?


Hard statistics are needed
How to measure the worth of the responses
◦ The responses are opinions
◦ Has thought gone into the response?

Survey data has been collected from 50
students
◦ Analysis of the survey data needs to be done

Find other fields where blogging can be used
◦ Collect and analyze data from results

Mike Zimmerman of Biology is working with
Lillian Cassel
Mike’s research is in paleopathology, the
study of the evidence of disease in ancient
remains
His career has involved fieldwork in Alaska
and Egypt and museum studies in Austria,
Canada and the United States



The raw materials of his papers and books
have been provided.
Over 100 of his published papers will be
placed in the digital library plus references to

J2 Micro Edition (J2ME) which is the version of the
Java 2.1 platform that is designed for use with
smaller devices such as PDA’s, mobile phones etc.
Since the size of small devices varies greatly, there
are two profiles provided by the J2ME. The
first,CLDC configuration , has a unique profile for
Mobile Information Device Profile (MIDP toolkit).
