Using MATLAB simulations for measuring MA with moving skew, kurtosis, autocorrelation, and cross-correlation identify the behavior of the stock's ups and down pattern.

emergency or navigation in an indoor big complex area is difficult and less accurate with GPS. 

 Increasing the accuracy of individual's location with the help of ultrasonic sound trans-receiver.

The general design of processor which can implement and modify for any task according to the requirement of the system. 

•  Instruction set
•  Logic gates and mux designing
•  Pipeline designing
• Implementation in FPGA

Designed 64kiB cache architecture using Jacobian algorithm to get optimize design of cache memory. 

Determining Factors:

Write Strategies

• Write back 
• write through allocate
• write through non-allocate

Replacement strategy

• Least Recently Used (LRU)

Burst Length

Cache line

Associative Set Size(N)

Operation:

By varying determining factors with jacobi algorithm using non-singular non diagonal matrix we have to determine the best cache design with higest hit and lowest miss.

Designed an accurate and low cost impedance meter just in $2 cost, with a wide range of measurement.Using arm7 cortex M4F.

Measurement Range

• It can measure  resistance ranging from 10 ohms to 400k.
• It can measure capacitance ranging from 1microF to 100nanoF.
• It can measure Inductance ranging from 100nanoH to 1000microH.

Operation:

•  To measure the component one must place the component on DUT points on daughterboard. 
• Now you can type the component name or you can choose auto measure and circuit will identify the component and measure it by itself. 

The main idea behind the project was to design a wheelchair for those who are partially or fully paralyzed. A paralyzed person can only take breath properly so our wheelchair can operate accurately on the breath of the operator.

I got some limited funding for the project so the total cost was under $150 dollars.

Components:

• Intel 8052 microcontroller 
• Two high precision infrared sensors
• Two DC geared motors 
• 20V and 5V, DC power supply
• High sensitive microphone
• LCD display panel  

Operation:

• When the operator breath out 1st time the LED panel will start working and it will show different options for moving. 
• The options- Forward, Backward, Left, and right will be displayed on the screen for few seconds. on the second breath, the operator will select the move.
• Obstacle sensors are used to prevent an accident.

Fully customized design of SDRAM from the interfacing with a processor to the mux design for every pin of the RAM. 

Power distribution and theft identification by using supervisory control and data acquisition computer networking system.

Using 8051 microcontroller

Developing multi-threading task with understanding semaphore and mutex.Learned the detailed concept of inter-task communication and prioritization

Abilities

• Thread Priority Inversion
• Task Priority Inheritance
• killing the task
• Restart the task and system as well.
• Shell command capabilities 
• CPU process monitoring
• Privilege and non-privilege  mode

 Kernel Functions:

1. Yield
2. Sleep 
3. Wait (Semaphore)
4. post (Semaphore)
5. createThread
6. distroyThread

Operation:

• The RTOS mechanism is working on Wait, Sleep, Yield.
• These task handlers help microcontroller to switch the task in-between.
• This RTOS can be operated as Preemptive and Co-operative multitasking.
• Co-operative: Relies solely on the process to relinquish control
• Preemptive: Using timer interrupt task time can be distributed .
