Security is now the most critical feature of any computing systems. Eliciting and analyzing security requirements in the early stages of the system development process is highly recommended to reduce security vulnerabilities which might be found in the later stages of the system development process. In order to address this issue, we will propose a new extension of the misuse case diagram for analyzing...
The keyboard switch is an important for today's advanced systems. This paper proposes a new type of emulated reactive keyboard switch by using piezoelectric devices. The proposed reactive switch consists of two elements of piezoelectric devices that sensed and actuated by DSP micro controller. We investigate how each reaction force of switches effects to the touch feeling via sensory test. According...
A method is proposed for measuring the spin rate of a ball moving through 3D space. The method uses only one high-speed camera and a uniquely marked ball. Five lines, each one a different color, are painted on the ball's equator and on its perpendicular great circle, enabling measurement of both the rotational angular velocity (spin rate) and translational velocity. The proposed measurement algorithm...
