Comparison of Performance Between Raw Oracle SQL and NHibernate ORM

This is a project of Database Sessional (CSE-304) based on Raw SQL and NHibernate ORM. We choose the dataset of "Stack Exchange" to run our query. We ran some selected queries in both Raw sql and NHibernate ORM. Then we compare the execution time of both of these. And By this way we will show which one is better in what cases.

Cost Efficient Touch Sensor

This Project aims to develop a cost efficient touch sensor . For this project we have used 16:1 mux which has 4 selector which can enable one pin at the mux at a time. In order to implement touch sensor we have used open circuit for each dot of the dot matrix. Each open circuit is represented by two pins . After putting on a gloves with a small piece of metal on the verge of finger . when the two pins will be touched together using the gloves metal on it , then that particular circuit is full. As a result corresponding dot of the dot matrix will be bright. Thus each dot of the dot matrix will be bright if we touch each pair of pins..
