5th sem is gone ......really a great feeling :)

Well we all know that taking a exam is a serious business, it makes you tensed, irritable, grumpy ...but those days are over, here we giving some hilarious images and as well as some really funny ideas to make exams worth taking like Make paper airplanes out of the exam..

19th of November 2011
exam is over on 18th and now i have to go my home on 22nd , and really right now i have no words to explain about that was in my mind at that time , i was so much excited and there were two reason of this excitation first one is that exam is over properly and second one is that now i am going to my home to take a deep breath for a long time ..........

6th Covocation on 12th of August 2011

Indian Institute of Information Technology, Allahabad announces its Sixth Convocation to be held on the 12th Day of August, 2011 and today ( on 11st august) i am going to home so i cant participated in it . But i am feeling good right now because i am going to home and i am excited .

Back To Home

Today, i'm going to my home on a 3 days long vacations on RAKSHA BANDHAN.

Mini Project ( 5th Sem )

                    A Detection Method for Routing Attacks of Wireless Sensor Network Based on
                                                        Fuzzy C-means Clustering

Abstract—Security is a critical challenge for creating robust
and reliable sensor networks. For the particularity and
security threats of wireless sensor networks, we proposed an
anomaly detection method based on Fuzzy C-means Clustering
(FCM) to detect routing attacks caused by abnormal flows in
this paper. This paper analyzes the datas from network
connections through the Fuzzy C-means Clustering methods to
detect routing attacks, and the empirical evidence shows its
efficiency and stability.

JAM(Just A Minute) Circuit (3rd & 4th Sem project)

This jam circuit can be used in quiz contests wherein any par- ticipant who presses his button (switch) before the other contestants, gets the first chance to answer a question. The circuit given here permits up to eight contestants with each one allotted a distinct number (1 to 8). The display will show the number of the contestant pressing his button before the others. Simultaneously, a buzzer will also sound. Both, the display as well as the buzzer have to be reset manually using a common reset switch. Initially, when reset switch S9 is momentarily pressed and released, all outputs of 74LS373 (IC1) transparent latch go �high� since all the input data lines are returned to Vcc via resistors R1 through R8. All eight outputs of IC1 are connected to inputs of priority encoder 74LS147 (IC2) as well as 8-input NAND gate 74LS30 (IC3). The output of IC3 thus becomes logic 0 which, after inversion by NAND gate N2, is applied to latch-enable pin 11 of IC1. With all input pins of IC2 being logic 1, its BCD output is 0000, which is applied to 7-segment decoder/driver 74LS47 (IC6) after inversion by hex inverter gates inside 74LS04 (IC5). Thus, on reset the display shows 0. When any one of the push-to-on switches�S1 through S8�is pressed, the corresponding output line of IC1 is latched at logic 0 level and the display indicates the number associated with the specific switch. At the same time, output pin 8 of IC3 becomes high, which causes outputs of both gates N1 and N2 to go to logic 0 state. Logic 0 output of gate N2 inhibits IC1, and thus pressing of any other switch S1 through S8 has no effect. Thus, the contestant who presses his switch first, jams the display to show only his number. In the unlikely event of simultaneous pressing (within few nano-seconds difference) of more than one switch, the higher priority number (switch no.) will be displayed. Simultaneously, the logic 0 output of gate N1 drives the buzzer via pnp transistor BC158 (T1). The buzzer as well the display can be reset (to show 0) by momentary pressing of reset switch S9 so that next round may start. Lab Note: The original circuit sent by the author has been modified as it did not jam the display, and a higher number switch (higher priority), even when pressed later, was able to change the displayed number.
