An innovative Volumetric Current Meter (VCM) was designed in order to allow quick velocity measurements in open channels. At first, the coefficient of velocity (Cv) of the device was determined through calibration under different water velocities in the laboratory. The measurement performance was verified by measurements performed in similar flows in irrigation channels using an ordinary curren...

there are many occasions where the base of a robotic manipulator is attached to a moving platform, such as on a moving ship, terrain or space shuttle. in this paper a dynamic model of a robotic manipulator mounted on a moving base is derived using both newton-euler and lagrange-euler methods. the presented models are simulated for a mitsubishi pa10-6ce robotic manipulator characteristics mounte...

The L4.verified project has produced a formal, machinechecked Isabelle/HOL proof that the C code of the seL4 OS microkernel correctly implements its abstract implementation. This paper briefly summarises the proof, its main implications and assumptions, reports on the experience in conducting such a large-scale verification, and finally lays out a vision how this formally verified kernel may be...

In this paper, a new broadcast encryption scheme is presented based on threshold secret sharing and secure multiparty computation. This scheme is maintained to be dynamic in that a broadcaster can broadcast a message to any of the dynamic groups of users in the system and it is also fair in the sense that no cheater is able to gain an unfair advantage over other users. Another important feature...

In Computer Science the guarantee that an algorithm has been verified to be correct does not guarantees that the numerical result obtained by it is correct. Hence, automatic result verification is an important additional tool to reduce the impact of arithmetic errors in numerical computation. As in traditional computation, one fundamental problem in verified computing is bounding the solution s...
