hey i am planning to make a robot that can find the transmitter in a room, when it reaches about some radius near transmitter it produces a beep. Method am planning to make use of is that the antenna in the bot which is directional should be rotated.The antenna is connected to analog to digital...
i am interested in discussing about the pros and cons of having a vesicle of ph sensitive polymer (with drug to be delivered inside it), inside a vesicle of thermosensitive polymer for drug delivery. This gives us dual control capabilities that is temperature and ph based trigger...
i am trying to design a robot which can track a transmitter which produces rf signals in a given range of frequencies(example:- 400-900 MHz). i want to know the following details.
1. i have a design of wireless robot with A433MHz RF modules. i need to change the frequency of transmission...
i am designing a heating element control system. i am looking for a relay(with 5V input voltage if possible or 12V) which can control an immersion rod with specification 16-A & 250 V AC. The following are my questions.
1. the heater has to be driven with power sockets(type M sockets -16A)...
I am an ECE. I just need to know precisely about Innovative engineering designs that caused the development of rural India. It should have created a revolution by solving the common man's problem. Give me 10 to 15 examples of such innovations produced. Please refrain from giving me examples like...
I belong to ECE department. I know some basics of DNA structure and DNA based sensors. With a DNA in hand can we predict the genetic disorders of a person? If yes how? which part of DNA possesses the characteristics of genetic disorders ? Also by taking the DNA of a women and hybridizing it with...
thats the transfer function i derived. now how can i find the gain bandwidth product of the opamp theoritically ? how can i determine it from the plot i posted previously and compare my results ?where alpha = R1/R1+R2
I Substituted A=GB/s not GB/2 sorry for the typo in the pic
i have attached a bode plot and the opamp dc second order lpf circuit. the opamp Tl082 has a gain bandwidth product of 4Mhz according to the datasheet. this circuit has a bandwidth of 414.25khz. can we determine the opamp' individual gain-bandwidth product from this plot ??
if yes , how do we...
The value of x or y can be 1 or 11. but all values of x with y being 1,will not satisfy the other two conditions. like
99*1=99 but
99-1=98 not a prime.
so i considered y=11, thus x+y should b greater than 11 n a square no: so it starts from 16(x+y) and goes on... but this method is ad...
sorry abt the fourth condition. what if first 3 conditions are considered ??
X+Y= square of a no.
X-Y=prime no.
X*Y=twin no. (eg 77)
what are the possible values of x and y. how to approach such a problem to narrow down our answers ??
X and Y are whole nos
X+Y= square of a no.
X-Y=prime no.
X*Y=twin no. (eg 77)
X/Y=irrational no.
how to solve such kind of problems apart from trial n error basis(ad hoc) ?
I am an engineering student. I am an average student. I don't think my methods of analysis and thinking are proper. I did take steps to improve my thinking abilities by becoming a left-handed person, solving sudoku and lateral thinking puzzles.
I want to be a scientist in my life. But i...
i presume u talk about the lorentz force. when a charge moves in a magnetic field it produces a force governed by f=q*(v x b) where b is a uniform mag. field. but y shud a moving charge be affected by this force ?? because moving charge produces its own magnetic field. if this charge has its...
