PROFESSIONAL EXPERIENCE:

Research Assistant

Confidential, Arlington

Responsibilities:

• Developed a growing training in Matlab for the Multilayer Perceptron (MLP) Neural Network.
• The growing training works with smaller networks and gradually grows the network to its full length.
• This training helps the MLP have better network initialization thereby avoiding the possibility of the training to find local minima.

Confidential

Android Developer

Responsibilities:

• Developed an Android game called Confidential .
• The application had the ability to detect user tap gesture on the screen and take actions upon the gesture.
• Used Eclipse IDE for development and Android Emulator for Testing.
• Used USB debugging to import the game to a real device for testing.
• Designed a RS-485 communication node (both master and slave node) using TIVA C Series TM4C123G and MAX3079EEPD in C language. RS-485 had a four-wire link configuration.
• This project had a UART interface to send commands to the nodes on the network.
• The design also implements a packet retransmission algorithm in case of packet loss.
• Developed an RTOS in both Cooperative and Preemptive mode in C with assembly programming with a one touch dynamic key selection at boot up to select between the two modes.
• The RTOS handled 9 processes with each process having a stack size of 1024 Bytes.
• The design also handled the task context switching in both cooperative and preemptive modes.
• Implemented the core kernel functions such as yield(), wait(), post(), createProcess(), destroyProcess().
• Created process queues for semaphore waiting.
• The design included a UART based command line interface (HyperTerminal) like a shell console in Linux to control (Destroy Process, Get Process ID, Create Process) the processes and to display the real time statistics (%CPU, Process ID, Semaphore Usage) related to the processes.
• Some of the commands supported are as follows: ps: Process statistics such as process name, process ID (PID), % CPU, process status. ipcs: shows semaphore usage. kill: kill a process using its PID or process name. pidof: Gets the PID of a running process.
• &: Starts the process if not already running. reboot: Reboots the controller.
• The RTOS also supported semaphores, yielding and system timers.
• Developed a method to solve the indoor localization problem to a resolution of 1 meter.
• For the purpose of demonstration, the system on the receiver side receives the IR signals and decodes the location information and displays it on a graphics LCD along with the room map.
• Design challenges included designing of the communication protocol and the packet structure to be transmitted.
• The transmitter used the bi-phase digital modulation for modulating the sequence data of the IR transmitters.
• Developed both the transmitter and Receiver system using ARM TIVA C Series TM4C123G and C programming language.
• Developed an Ethernet application in C with the ARM TIVA C Series TM4C123G Controller.
• The Application could send and receive internet packets, decode the received packets and process the packet headers and extract the data from the packet.Designed a system capable of capturing analog signals and generating various waveforms.
• This project also had a command line interface capable of controlling the system and providing measurement data back to the user.
• Developed a complete packet-sniffing tool in Python to analyze network packets.
• Design also included a GUI for user control of the real time packet sniffing and network analysis report (Throughput, network diameter, Congestion Window) from the acquired data.
• Designed an SDRAM controller that allows SDRAM memory to be interfaced with a microprocessor (80386SX) having only asynchronous memory support.
• Added the functionality of having a programmable burst length.
• Implemented state diagrams for the complete design.
