RemarksEditor’sEditor’s Kay Chen Tan

National University of Singapore, SINGAPORE

The 2012 IEEE Panel of Editors meeting took place in San

Francisco, California and I was pleased to be one of the

attendees at this meeting. It was a fruitful meeting where

various matters were discussed and updated; such as moving

towards open access journal, interactive content update, author

network and mobile products development etc. I believe these ini-

tiatives will benefit our publications greatly and provide greater

values to the members of CIS.

In this issue, we feature the applications of Type-2 fuzzy logic systems. Fuzzy

logic surrounds us even if we have not been consciously aware of its presence. My

bowl of rice for dinner is cooked with a fuzzy logic embedded rice cooker that

possesses the intelligence to sense the amount of rice and water necessary to cook

up a perfect pot of rice. The fragrance of the fuzzy cooked rice never fails to make

me hungry!

And while I’m satisfying my hunger pangs, my laundry is in a fuzzy logic

embedded washing machine that senses the amount of clothes in the washing drum

so as to fill up with the appropriate amount of water to ensure the clothes are

thoroughly washed, while reducing water wastage. How convenient! It has certainly

come a long way since Professor Lotfi A. Zadeh introduced the concept of fuzzy

logic in 1973.

We have entered now into the realm of real world applications for Type-2 fuzzy

logic; where the prevalence of human uncertainties is taken into account and Type-2

To bring this new website to you,

many of our society members have

worked very hard to make this happen.

The conversations of developing a new

website for better service for our soci-

ety started about two years ago under

the leadership of Gary Yen and the pre-

vious Webmaster team Jeen-Shing

Wang and Wan-Yu Jhuang. Since then,

many discussions and meetings have

been organized and a collaborative

team was formed to ensure this moves

forward smoothly and efficiently. In this

process, CIS has provided tremendous

support and help for the entire devel-

opment and launching procedure. This

new website could have not been

accomplished without the great leader-

ship and visionary guidance of Marios

Polycarpou (CIS President), Gary Yen

(CIS Past President), and Pablo Estevez

(VP Members Activities). Many of the

detailed development work have been

accomplished with a great collaborative

team including Tom Monaco, Jo-Ellen

Snyder, and John Wettlaufer. Further-

more, during the internal review pro-

cess, the EXCOM and ADCOM have

also provided detailed comments, sug-

gestions, and feedback for us to further

improve the appearance and functions

of the website. Without all the great

coordination and dedicated work from

everyone in the team, this new website

could have not been possible to the

current stage!

Whether you are an existing mem-

ber of CIS, or just a new visitor to our

society, I invite you to explore our

new web home so you can see all the

exciting research and education infor-

mation and activities in our society.

Should you have any suggestions or

comments for our website, please feel

free to contact us at Haibo He (he@

ele.uri.edu, CIS Website Manager),

Pablo Estevez ([email protected],

VP Members Activities) and IEEE CIS

staff at [email protected].

We hope you will enjoy our new

web home http://cis.ieee.org/, and

Having Fun!

Editor’s Remarks (continued from page 2)

fuzzy logic is applied in different

aspects of our everyday life. Besides

household appliances, Type-2 fuzzy

logic has found its way into comput-

ing-dependent industr ies including

banking, finance and energy genera-

tion, as highlighted in this issue’s fea-

ture article “Towards the Wide Spread

Use of Type-2 Fuzzy Logic Systems in

Real World Applications.”

As advancements are made in imag-

ing, Type-2 fuzzy logic has made similar

advances and has been employed to

reduce noise while enhancing image

quality. This is explored and analyzed in

another article featured in this issue

“Application of Type-2 Fuzzy Logic Fil-

tering to Reduce Noise in Color Imag-

es.” In our pursuit for perfect, logical,

non-emotional decision-making process-

es, especially in a commercial context, we

rely on computers to assist us. Our next

feature article addresses the “Challenges

for Perceptual Computer Applications

and How They Were Overcome,” bring-

ing us another step closer to perfection.

But perhaps before we go further,

we need to consider the confusion

present in Type-2 fuzzy logic for as

much as it handles uncertainties, there

are some “fuzziness” present within the

logic itself, which are addressed in the

Discussion Forum article “Type-2

Fuzzy Logic: Challenges and Miscon-

ceptions.” In addition to the application

notes and book review in this issue, we

are pleased to have the IEEE CIS Stu-

dent Member Activities Subcommittee

giving us an update on what has been

happening on their end, a report on

the salient features of the new IEEE

CIS web site, and an update by the

IEEE CIS Philippines Chapter which

was newly established in 2011.

We have passed more than the half

year mark for 2012 in the blink of an

eye. We hope you have enjoyed the

magazine as much as we have enjoyed

putting it together for you. The success

of this publication depends greatly on

your active participation, submission of

new research findings, sharing of ideas

and valuable feedback. On behalf of the

Editorial Board, I encourage you to

contact me at [email protected] with

any comments and suggestions.

Till our next issue, we wish you a

fruitful last quarter for 2012!
