DGCEAS Recognizes Jerry Gibbon as 2005 Engineer of the YearBy Tim Weil
Washington Section Editor
At its February awards banquet,the District of Columbia Council ofEngineering and Architectural Soci-eties (DCCEAS) presented the 2005Engineer of the Year award to JerryCibbon, a Senior Member of the IEEEWashington Section.
The DCCEAS banquet was a high-light of the activities surroundingNational Engineers Week here in thenation's capitol. The evening programwas directed by Dr. Issa Khozeimeh,vice president of DCCEAS. In recog-nizing Mr. Gibbon's lifetime achieve-ments, Dr. Khozeimeh remarked on thecrucial role of engineers in our society.
"The general public has a gocCperception of the engineer. We as engi-
neers are reliable, trustworthy, and inshort, problem solvers. National Engi-neers Week allows us to showcase ourtalents and abilities that tum ideas intorealities. Engineers are the very profes-sion that makes things happen in oureveryday lives," she said.
Mr. Gibbon's career in electricaland telecommunications engineer-ing spans more than 40 years in themilitary, federal, commercial andeducation sectors. His contributionsand recognition within IEEE includeserving as the current chair of theIEEE Region 2 South Area, and as pastchair of the National Capital AreaCouncil, the Washington Section andthe section's Communications Societychapter. He is a recipient of the IEEETl-rird N{iltrcnnium }v{e.lal and tv,'r,Federal Bronze Medals.
Currently, Mr. Gibbon is principalof ]&BC Consultants in Falls Church,Virginia, a teiecommunications engi-neering and management-consulting
firm. He also serves on the CapitolCollege Board of Trustees, chairs thecollege's Alumni Advisory Board, andis a Fellow of the colleo"

Gommercializing tflt0MIMO (multiple-in, multiple-ott) wireless is
emerging as an important technology to enhancewireless performanie. This talk wilI focus on theengineering aspects and tradeoffs in developingearly MIMO prqducts for the commercial market-place. A key feature of MMO systems is the abilityto turn multipath propagation, traditionally a pitfallof wireless transmission, into a benefit. MIMO hasevolved (and is still evolving), since its beginning in1993, with contributions from hundreds of research-ers around the world. Some aspects of MIMO havealready entered wireless standards, and many morestandards efforts are ongolng.. Multiple antennas at each end of a MIMO link
can be us€d in different modes such as transmit-reeeive diversity, beamforming, antenna subsetselection and spatial multiplexing. Which mode oroption actually maxitnizes performance depends onthe channel conditions and system SNR and QoSrequiramenb, among other factors. Other imp0rtantissues to consider fo.r comrnercial MIMO systemsare the overall system cosf power consumption andmanufacturability.
Victor Shtrom is the chief wireless architectat Video54, whidr designs MIMO sqtart antennasystems for enterthinmentquality wireless homevideo. He received his Ph.D. in communicationtheory from University of Cincinnati. He has beeninvolved in smart antenna research and development from his first industry job with ArgoSystems,where he developed algorithms for the cellulartelephone interference cancellation beamformer.After ArgoSystems was acquired by Boeing, he

Photonic cr,,stal fibers @CFs) havebeen the focus of increasing scientificand technological interest since thefirst working example was reportedin 1995. Although superficially similarto a conventional optical fiber, PCFhas a unique microstructure, consist-ing of an array of microscopic holes(i,e.; channels) running along its entirelength. These- holes act as optical barri-ers or scatterers, which, whbn suitablyarranged, can "comal" light within acentral core (either hollow or madeof solid glass). The holes can rangein diameter from appror 25 nm to 50nm. Although most PCF is fqrmed inpure silica glass, it has.also recentlybeen made using polymers and non-silica glasses, where it is difficult tofind compatible core and claddingmaterials suitable for conventionaltotal intemal reflection guidance. PCFsupports two ggidance mechanisuls:total internal reflectioru in which case'the core must have a highe. averagerefractive index than the holey clad-ding; and a two-dimensional photonicbandgap, when the index of the core isnot critical - it can be hollow or filledwith material. Ught can be conholledand transforrred in these fibers withunprecedented freedom, allowig{orexample the guiding of light in a hol-low core, ttre creation of highly nonlin-ear solid coreg with anomalous disper-sion in the visible, and the design offibers that support only one transversespatial mode at all wavelengths. ThePCF concept has usher€d in a new
a and more versatile era of fiber optics,with a multitude of different applica-tions spanr-ring many areas of science.Recent reviews are available rn Science

AVisit to Delhi-Wa,shington's Sister SectionBy Saj Durrani
Past Chair, Washington Section
Lr lanuary, I had the pleasureof visiting thrce IEEE Sections inIndia) under the auspices of theAerospace and Electronic SystemsSociet5/s Distinguished LecturersProgram (DLP).It all started whenDr. M,A. Ioshi, a professor at thePune [rstitute of Engineering andTechnology, asked tre to give atutorial on saiellite communica-tions at a confererrce that she wasorganizing. Dr. ]. Vasi, a past chair ofthe Bombay Sectioru leamed aboutit, and asled me to speak there aswell. My plan was to fly to Delhiafter Bombay (or Mumbai, as it iscalled now), andthmgoto Pakistanfor a family visit. An old IEEE friend,Dr. RG. Gupta, who has held manyoffices in the Delhi Sectioru askedme to speak there also.
As some of you may recall, itwas reported in the Scirnner in 2001
that the Washin$on and Delhi Sec-tions had become sister sections,the first such pair iri tt " IEEE. Ihad intended to visit Delhi duringa priwate ttip that year and wouldhaye conveyed our section's greet-ings, but had to cancel the trip dueto Gupta
allow
with the current sbction chair, Dr. Sub-rata Mukhopadhyay, and some otherofficers. They held a brief ceremony atthe end of my talk when we exchangedgreetings by the sister sections. t toldthe group that this "sister relation-ship" came about primarily due tg $eefforts of Dr. Shyam Bajpar, who wasthe Washington Section chafu in 2001.
Shya* leamed that the IEIE Boardo_f Directors had appioved the ideaof sister sections, and he took on thetask of forming a linkbetween the twocapital cities. He contacted his coun-terpart in Delhi, Dr. Balasubramanian,who welcomed the idea. It took a lotof effort on their part, but they gotapprovalb from the two regional dircc-tors, the Re.gionalActivities Board, andother relevant bodies, and finally theWashington and Delhi sections wenedeclared sister sections. I was especial-ly pleased that Dr. Balasubramanianwas able to attend the function, andthanked him for his efforts four yearsago to estatlish the sister relation-ship. Dr. Mukhopadhyay ended thecergmony by asking me to convey theDelhi Sectiqn's compliments and goodrlvistes to the Washington Section,'My wife accompanied me on this
trip, which was her first to lrdia. Mum-bai is a bustling financial metnopolis.
. Pune is a meditirii siie city witli many '
colleges, including an engineering col-lege for women. Delhi needs no intro-duction; it has many historical build-ings and monuments, some of which
have been designated.as parts ofthe World Cultural Heritage. Wealso took a side trip to Agra. TheTaj Mahal fully stood up to itsreputation as one of the wondersof the world, and I was struck bythe restorations of tlre main monu-ment and improvements in and'around the grounds since my lastvisit about 20 years ago. IAIe alsovisited some forts'' and.shrines,including a 72 m&r tower builtin the 12th century and the tombsof two poets from the Mogul era,about whom I used to read in *ycollege days.
Our total stay in India was rathershort-just shy of two weeks-*utwe covered a lot of ground. I was .
impressed by the high caliber ofIndian univercitieg,. especially thetrIs. Many of their alumni havedoge well in their prcfessio:r andhave'made generotrs donations totheir alma maters. i
' After India we wcnt to Pakistanfe a week to visit'family and oldfriends in I^ahore and Islamabad.I was pleased to learn tbt theIEEE,was inlgood hartds the*e, too,' ,

FIRST (ForJnspiration and Rmog-nition of Science and Technologf) isan organization dedicated to provid-ing "inn6vative programs to buildself-confidence, knowledge and lifeskills while motivating young peopleto pursue opportunities in science,technology qnd engineering" TheFIRST robotfics competition marksthe end of an intense six-week peri-od during nhich the students havethe opportunity to learn about work-ing as a teary sharing ideas, makingtradeoffu, mating mistakes, makingsomething, making something work,figudng out why something doesn-twork, and many other things. Tomake the program "happen" at eachschool requires a team of adults frcmboth inside and outside the institu-tion. Support is needed in areas oforganization, logistics, fund raising,communications and engineering.
Brrilding a ,rcbot is an engineer-ing-intensive activity requiringexpertise from multiple engineer-ing disciplines, but building andmaintaining a robotics team is aneven bigger challenge. The studentsinvolved rn the program have vary-ing degrees of expertise and sklllsin math, physics, communications,web design programrdng and otherdisciplines. What they may lack inexpertise is more than cortrpensatedfor by their energy and enthtrsiasm.The "glue" of a successful program isthe adult mentors, who help hamessand direct the energy of the studentsby providin g " real world" experienceand insight.
I have served as a mentor forthe Oakton High School robotics
Best Vfebsite Award. The team'sIEEE meurber mentor, Charles Har-ris, received the prestigious VCURegional Woodie Flowers Arrard forhis sustained contribritions.
Our congratulations to bothteams, and we look f6rward to sup-porting EIRST Robotics teams in thecoming yeani.
,""ry, for the pasi three years andhave found it.to be oni of the mostrewarding acti-vities'that I hav'e hadthe opportunity to particiBatg,in, Amentor is part coach, part teacher,and part manager. I\nro of the mostimportant skills are being a goodlistener and asking pertinent ques-tioru which htilp guide and facilitatediscussions. A mentor le*s the groupgo ahead on their own when they arecapable, but is there to bridge gapsand guide choices to help bring theproject to fruition.
The game played with the robotis not the only aspect of the com-petition. Awards are given in manyother categories such as: best website, CAD desigR, animation, andthe prestigious Chairiran's Award.Adult interaction with each group ofstudents on the team is essential inachieving the goals of the program.
During the "preseason" lead-ing .rp to the "build period," manyteams conduct sessions to-help teadtstudents skill sets in areai such as:proper use of hand tools, web pagelayout, el6ctrieal wiring techniques,pneumatic systems, electric motors,design software, -project, planningand management animation soft'ware, and computer/sensor inter-facing. Mentors from a variety ofdifferent backgrounds are needed tohelp conduct these sessions as wellas to help during the six week buildperiod.

lllllA Gonference Focuses 0n Securi$ EngineeringBy Tim Weil
Washington Section Editor
The Third IEEE InternationalWorkshop on Information Assur-ance (IIMA) convened with a
two-day program in March atthe University of Maryland'sComputer Science InstructionalCenter in College Park. More than30 atterrdees from university, gov-emment and private sectors tookpart in the presentation of formalpapers addressing the togics ofmalicious software (malware),mobile ad-hoc network (N{ANET)security, IA simulation and policy,and intrusion detection systems(IDS). Among the presenters werefaculty, researchers and doctoralcandidates from European andAmerican universities.
A diverse range of discussion topics included-counter-measures for code'injection attacks, wormcontainrnerrt algorithms, MAI{ET IDS architecture,survivability against wireless LAN attacks, visual-ization,methods for IDS, risk assessment modeling,forensic analysis of file system intrusions, and )OML-
Guard proposals for ServiceOrieriied' Arrhitectures.' .
Dr. Roger Schell highlighted the worlalrql witha keynote presentation on "Creating HiS, Assur-ance for a Froduct lesson leamed from GEMSOS."His tatk.focirsed;ion.the al&ite*rrye of, GzuSOS,the only general-purpoee operating systeni, kemelin ttrc world rated Class.Al: Verified Protection bythe National Secudty Ag*"y. Dr. Schell's remarksemphasizecl that in the area of informetion assura4ce,
"security is not a'probabilistic event.'{ Towards thatend, he descdbed a software engineering methodol-ory which has evollved from the security models ofthe Trusted Computer Secudty Evaluation Criteria(TCSECOrange Book) up to modem Common Cri-teria standardization frameworks.
IWIA 2005 was organized irnder the sponsorshipof the IEEE Computer Society and its Task Force onInfonnationAssurance (fTIA), and held in coopera-tion with the Association for Computing Madrinery(ACM) special interest group on Security, Audit andControl.
