Every time we detect a part that is out of tolerance, the implication is that something went wrong in the machining process: either the operator made a mistake, or the machine tool did. A lot of the time, problems with the machine get blamed on the operator. Rather than expect the operator to compensate for every machine tool problem -at the expense of increased setup time and scrap -it makes m...

The non-autonomous bouncing ball system consists of a point mass m in a constant gravitational field g, which bounces inelastically on a flat vibrating table. The presented Lyapunov-like method is set up for non-autonomous measure differential inclusions and constructs a decreasing step function W above the oscillating Lyapunov function V . Furthermore, it is proven that the attractivity of the...

In the present study, flow over flat and pooled stepped spillways was simulated three dimensionally. The VOF method and k- ε (RNG) turbulent model was used to simulate the flow over the stepped spillway. The results indicated that the numerical model was acceptably capable of simulating the flow over the pooled and flat stepped spillways for different discharges. Following that, the effect of d...

OpenPuff is recognised as one of the leading tools in video steganography for its capability to securely hide information. This is in contrast to a number of video steganography tools that apply outdated and highly insecure techniques such as EOF data injection. However, even OpenPuff has subtle vulnerabilities that can be easily exploited. In this talk we propose a method to detect the presenc...
