The primary goal of this paper is to study a nonlinear complementarity system (NCS, for short) with and nonhomogeneous partial differential operator mixed boundary conditions, simultaneous distributed-boundary optimal control problem governed by (NCS), respectively. First, we formulate the weak formulation (NCS) variational inequality double obstacle constraints (MVI, short), prove existence un...

We present an automatic method for computing tight upper bounds on the iteration number of special classes of program loops. These upper bounds are further used in the WCET analysis of programs. Program flow is refined using SMT reasoning, rewriting multi-path loops into single-path ones. Single-path loops are further translated into a set of recurrence relations over program variables. To solv...

Calibration of movement tracking systems is a difficult problem faced by both animals and robots. The ability to continuously calibrate changing systems is essential for animals as they grow or are injured, and highly desirable for robot control or mapping systems due to the possibility of component wear, modification, damage and their deployment on varied robotic platforms. In this paper we us...

This demo showcases breakthrough results in the general field real-time simultaneous localisation and mapping (SLAM) using vision and in particular its vital role in enabling a wearable robot to assist its user. It accompanies the full paper by the same authors at ISMAR2003 [1]. In our approach, a wearable active vision system (“wearable robot”) is mounted at the shoulder. As the wearer moves a...

Formal checking at Register-Transfer Level (RTL) is currently a fundamental step in the design of hardware circuits. Most tools for formal checking, however, work at the boolean level, which is not expressive enough to capture the abstract, high level (e.g., structural, word level) information of RTL designs. Tools for formal checking are thus confronted with problems which are “flattened” down...
