Career Counseling Meet IIIIEEE-PNEC organized the 3rd Career Counseling meet on 17th November 2011. The objective was to create awareness among the undergraduate students about what is expected of them in industry and particularly, how to get there. Deputy General Manager HR, SSGC was the first one on the speakers list. Amid all the jokes and laughs he cracked at the future engineers, he addressed some really important issues regarding job placement and how to succeed in ones profession. The next speaker to come on stage was the representative from PPL, Mr. Bilal Ahmad Khan, who answered questions about the hiring process of PPL and dos and donts of a job interview. Microsoft representatives enlightened the audience about their engineering and technology competitions internship opportunities. They explained Imagine Cup, a global competition held annually, with participation all across the world. Visioni explained the CV writing process and the steps to ace your interview.

On September 15, 2011 IEEE PNEC launched a weekly lecture series called SPARKLE. Short for System Providing Access to Research Knowledge Learning and Education, SPARKLE aims to broaden the scope of to-be engineers knowledge while promoting a progressive culture of research and innovation amongst the students. So far we have learned about Has-san Idreess experience of attending the R10 SC 11 in New Zealand, Fundamentals of GSM technology, Re-cent Advancement in Optical Communication, Practical Implementation of Data Encryption, Dos and Donts of Final Year Project, Problems faced by Women in the field and to How to be Irreplaceable at Work which was delivered by the honorable Dean EPE, Capt. S.M. Babur.

Robotics WorkshopIEEE PNEC organized a Robotics workshop for the students of PNEC. The workshop focused on constructing and designing a robot from scratch operating on wall detection, line following and line seeking. Workshop was conducted under the supervision of Dr AttaUllah Memon and was conducted by a final year student, Rameez Qasim, who is also the Special Project Officer IEEE PNEC. Workshop was a success amongst the enthusiasts with a good percentage ending up with a working robot.

Techfest 11WIE IEEE PNEC was honored to hold its annual event, the TECH-FEST this year on 21st December 2011. Tech-Fest is the biggest event organized by WIE IEEE PNEC. This time, Tech-Fest had more innovations and novelties with the fun filling Poster Design Competition, the interesting & informative Quiztronic & the enlightening Speaker Session. The Commandant, Rear Admiral Syed Imdad Imam Jaffri graced the occasion with his presence. In his closing speech, he appreciated the efforts of WIE IEEE PNEC and encouraged the students to regularly take part in such mind freshening activities.

USEFP Interactive Session

On 14th of December 2011, IEEE-PNEC arranged an informative session regarding the United States Educational Foundation Program for students of NUST PNEC where we received a number of eager students from the 1st, 2nd and 3rd semester. The exchange program focuses on higher educational experiences in the U.S. and Pakistan. Another objective of this program is to create awareness among the western society of our existence in the modern world, imparting cultural values and eradicating certain prejudices.

WIE Trip to PN Model SchoolThe Women in Engineering Affinity Group-Pakistan Navy Engineering College (PNEC) at Karachi has been immensely active throughout the year of 2011. One of the highlights was to create awareness regarding the field of engineering among the younger generations. In this regard, WIE-PNEC and its volunteers arranged a trip to PN Model School, Karsaz. The aim was to brief younger minds about the vast field of engineering, our college and need-less to say, Women In Engineering. An interactive session was held with the students of matriculation and above on 25th November 2011.

RFID - Its Applications and InterfacingBy Usman Yousuf - Student at National University of Sciences & TechnologyWhat is RFID or Radio Frequency Identification?RFID is a means of capturing data about an object without using a human to read the data, the object is identified using this data. Data transmitted by each object (tag) is unique and can be used as a key. RFID and Barcodes both belong to a group of technologies called Automatic Identification and Data Capture. An RFID tag is just like a barcode but RFID communicates its digital code through radio frequency while barcode is an optical code. An RFID based system consists of a reader, a tag (transponder or carrier) and a computer/controller. Reader is a Two-way radio transmitter-receiver which sends a signal to the tag and read its response. The readers generally transmit their observations to a computer system running RFID software or RFID middleware. Readers are a power source for Passive tags. Interfacing an RFID reader module with microcontroller or a computer is not a rocket science. Its simply serial communication of the two devices. Most of the reader modules transmit the data and tag ID at 9600baud which is standard baud rate. Output voltage level depends upon the reader, some readers transmit according to RS232 standards while others transmit TTL/CMOS level. If a reader is of RS232 type a middleware IC is required to interface it with Block diagram of Interfacing RFID reader with microcontroller CMOS type microcontroller. An RFID tag or a transponder is the actual key. The tag's information is stored electronically in a non-volatile memory chip. RFID tags contain at least two parts: an integrated circuit for storing and processing information, modulating and demodulating a radio-frequency (RF) signal, collecting DC power from the incident reader signal, and other specialized functions; and an antenna for receiving and transmitting the signal. The RFID tag includes a small RF transmitter and receiver. An RFID reader transmits an encoded radio signal to interrogate the tag. The tag receives the message and responds with its identification information usually 10 to 16 digits in length. This may be only a unique tag serial number, or may be product-related information such as a stock number, lot or batch number, production date, or other specific information. RFID tags can be either passive, active or battery assisted passive. An active tag has an on-board battery that periodically transmits its ID signal. A battery assisted passive (BAP) has a small battery on board that is activated when in the presence of a RFID reader. A passive tag is cheaper and smaller because it has no battery. Instead, the tag uses the radio energy transmitted by the reader as its energy source. The interrogator must be close for RF field to be high enough to transCommonly available Tags Implantable Tag fer enough power to the tag. RFID systems are more reliable as compared to barcode or magnetic card system. Since every tag has a unique ID they can easily be used for personal identification and thus have a wide range of applications. Most applications use passive tags, active tags have long range and mostly used for military purposes. Most commonly used passive tags operate at frequency of 135 kHz. RFIDs have been used in animal husbandry and object tracking since long. Currently RFID is used in bill payment, product tracking, passports, identification, attendance, log keeping and access control system. In medical science RFID implants are used to store primary disease or allergies of patients admitted to certain hospitals, such tags are implanted in right arm. Encrypted tags are used for sensitive security systems. One of the most commonly observed application in Pakistan is the Motorway e-toll system.

Graphene - Thin Stuff A Big Fat Deal!By Onib Nasir - Student at National University of Sciences & TechnologyEver thought the lead in the pencil that we use to be worthy enough of winning the Nobel Physics Prize? It is indeed true! Professors Geim and Nosolev were awarded the prestigious accolade of the Nobel Physics Prize in 2010 for their research on graphene and its properties. Graphene is the name given to a flat monolayer of carbon atoms tightly packed into a twodimensional honeycomb lattice and is the building block for graphitic materials of all other dimensionalities. It can b
