Physics Questions Solution

Hello All

I have uploaded a set of Physics questions needing solutions. Some of the questions might be repeated , so you can avoid doing them twice. All I need is for someone to provide basic and straightforward solutions to the questions within the shortest possible time. Preference should be for short explanations to the theory questions and calculations should be as short as possible.

Motion Compensation Block For H.264 Implementing In Matlab

Hello,

I am working on video codec H.264. I am coding module in MATLAB. I want someone who can work on motion compensation module. Here is wiki link which gives you very rough overview.
http://en.wikipedia.org/wiki/Motion_compensation
It mentioned motion compensation methods such as VBSMC, OBMC, Qpel and Half pixel Motion compensation. I wanted to implement any of two in matlab, and compare performance based on MSE, PSNR.
Entropy coder and decoder will be implemented in matlab after Motion compensation block has been finished.
I need someone who can work on both or either. I have some reference material for motion compensation, but not for entropy coder-decoder.

I am working on VSMC using bottom up approach, and used huang lin report as reference.

Explicit Scheme Of Burger’s Equation

I need an explicit scheme of Burgers equation with two degree accuracy in both time and space. I have developed such a scheme but which actually give more errors than the scheme with one degree accuracy in both time and space.
I have the data of u for h=.1, k=.01. and for other one combination of h and k which is attached as ua.mat file.
I have also attached the mat file to calculated the error for my new scheme.

Small Assignment Of Infrared Music Transmission System

This assignment is based on student budget.

The circuits are consist of Transmitter and Receiver, those two circuits are transmitted by Infrared LED (Tx & Rx).
It would be a simulation of the circuits, and the components hardware in the breadboard.

Illustration:
Mono or Stereo jack is connected from the transmitter, and we must have a tuner (variable resistor in transmitter) to tuning the volume, then we can hear the sound from the transmitter respectively.

The Objectives:
*Able to hear the sound at the transmitter as well as the input music (with any modulation technique, AM is preferable)
*Adjust the tuner, as to be the volume control of the sound

Components:
We can use any types of components. Simple basic Amplifier is recommended.
No need Programmable IC or microcontroller Unit. Just use an IC or OP-AMP chips.

The components that available at the moment right now,
*Transistor NPN BC548 and PNP 558,
*Mono Speaker 8 Ohms,
*UM66 and LM 386 for music,
*OP-AMP 741,
*Diode Zener 3.2 V,
*3 pairs of LEDs Transmitter and Receiver,
*Male jack 3.5mm (due to connection cable from computer to hardware),
*Female stereo and mono for jack 3.5mm cable,
*Voltage regulator,
*Some Capacitors and Resistors,
*Battery 9V 2pcs,
*Variable Resistors 10k Ohm, 100k Ohm

http://forum.allaboutcircuits.com/showthread.php?t=3483

http://www.scribd.com/doc/12852897/IR-Music-Transmission-and-Reception-JNTU-Atp

Budget is not more than $40. And the complete period would be just 3 days, from the day it posted.
Submission Maximum at Monday April 4th.

Description of Works:

1) Simulation of schematic the current circuits for both transmitter and receiver, by using Multisim or Proteus.
This simulation may be successful in the process, but it must applied to the actual components until the project works.

2) Full explanations of the simulation part. (Ms. Word files and component datasheets)

For instance;
* What modulation technique do we use.
* Basic calculations or any equations that require in the simulations
* Why we use this type of amplifiers? (i.e. OP-AMP 741)
* What the purposes of these resistor of … Ohm, Capacitor or any IC in the circuit,
* If the transmitter use modulation, how the demodulation signal going through at receiver,
* If the sound it is not clear as the input, what happened to the signals?
* Why it come with noise at the receiver?
* And other explanations, regarding how the circuit works properly.

NOTE : The job is only the schematic simulations in the software ($25) and full explanations of why it works and operates, I would ask some questions if necessary ($15). Therefore I will construct the hardware in the breadboard myself.

SD Card EyeFi Power Modification -SD

Various Budget Bid are welcome.

I am needing to use a EyeFi SD card inside of a Bushnell 119435C to transfer pictures taken automatically to my iPhone. The EyeFi card has the software infrastructure to handle this. The card automatically transfers pictures when it is on a WiFi network and the iPhone has an application to recieve these pictures.

However, this trail camera uses a motion detecting system that power on only when something is moving in front of it, it then only powers up long enough to take the picture and save the picture to the card. At that point the power to the SD card is turned off. This does not give the card ample time to transmit the picture.

I need a solution for the power to stay on longer to give the card time to transfer. This needs to be done on the card side NOT the camera side. I need to the card to tell the camera to stay on longer. This needs to be able to work with other similar make and model cameras so updating camera software or in anyway modifying the camera is not an option.

This project is going to be pursued asap. Please provide your solution and we will begin immediately.

Low Budget with High Experience given Preference

RC TO GSM/GPRS/GPS CONTROLLED CAR

Hi Engineers.

My title says it all. I want to control an RC car or plane or helicopter using gsm/gprs.

Transmitters in remote controls are usually low distance. I want to be able to control it over long distances. I can only think of GSM; If you have other ideas please advise. Lets say i have a plane and want to fly it 100km away (if fuel was no problem for now). I want to control it with my pc; keyboard or joystick/pad. I would also want to have a camera on board the plane for which i can have a view.

Project must be completed with detailed instructions.

Thanks
Sam

IPad Case Plus….

We need a talented and creative Product Engineer to create an iPad case. We are flexible as to which 3D program you choose to use. The unique aspects of the cover will be discussed at the start of the project. Without giving away details as to how the cover will function I will say that it may have a few small movable parts and some unique functionality. The 3D renderings should be delivered to us in full and if needed in a sperate format that can be sent and understood by our factory. We will expect at least one included revision after the first prototype and can discuss future revision costs. Experience with different types of plastics would be a plus.

Along with your quote please also provide previous work that you have done and why you believe you are qualified for this job.

(There has been some confusion with the description. To clarify, there will be no electronics in the case other then the iPad itself and the iPad will not actually control anything in the cover or connect to it in any way other then being held by the cover.)
