Echo Server was an application developed using Windows API in C. This application was a performance comparison between Multi-processing and Multi-threading.
Multiple users could connect through LAN with this application and for each connected user a new process or thread was created dynamically and was destroyed at disconnection. Performance evaluation was found to be dependant between number of cores available and for best response, a trade-off solution was found to be mixture of… Mehr anzeigen

Echo Server was an application developed using Windows API in C. This application was a performance comparison between Multi-processing and Multi-threading.
Multiple users could connect through LAN with this application and for each connected user a new process or thread was created dynamically and was destroyed at disconnection. Performance evaluation was found to be dependant between number of cores available and for best response, a trade-off solution was found to be mixture of multi-threading and multi-processing. Exploiting the multi-core hardware, multi-processing solution proved to be much better candidate with each process affined to a distinct core and load balancing, and robust. While the multi-threaded was better in response time but wasn't robust. Therefore, a mixture of multi-processing and multi-threading with multi-core hardware solution was evaluated with the best results. Weniger anzeigen

Handroid, a glove interface equipped with multiple sensors that recognizes human hand gestures. The purpose of the project is to:
1. Act as a connection between people who cannot speak and use sign language to communicate, and people who don't know sign language.
2. Propose using human hand as controller for different machinery.

This hardware project was designed using logic circuitry that senses the water level and decides whether to turn off or turn on the water refilling pump. Two bare wires (used as sensors) were placed at 10% and 90% of tank's capacity. If water level dropped below 10% of the tank, the pump was activated until 90% of the tank filled and remains off until water level goes below 10%. It also monitored pump state (ON/OFF) before making the decision. The difference of water level also took care of… Mehr anzeigen

This hardware project was designed using logic circuitry that senses the water level and decides whether to turn off or turn on the water refilling pump. Two bare wires (used as sensors) were placed at 10% and 90% of tank's capacity. If water level dropped below 10% of the tank, the pump was activated until 90% of the tank filled and remains off until water level goes below 10%. It also monitored pump state (ON/OFF) before making the decision. The difference of water level also took care of differential gap to prevent frequent turning ON/OFF of the pump.
Boolean Function used: E = L + HE' where E is the final decision of pump, L is the 10% of tank's capacity, H is the 90% of tank's capacity, and E' is the current state of pump.
Hardware used were:
-- 2 ICs for AND gate and OR gate.
-- 5 Volt regulator IC.
-- NPN Transistor to control the switching of pump.
-- Resistors and capacitors as interfacing components.
-- 5Volt Small DC Motor.
-- Dual Layered PCB designed in EasyPCB. Weniger anzeigen
