Abstract:
The design and implementation of critical controllers benefit from development in a formal method such as B. However, B does not support execution specification directly, which is a requirement in controller design. The aim here is to develop a set of annotations so that they can be used by a B design engineer to capture execution requirements, while creating the B model. The annotations, once shown to be machine-annotation consistent with the B machine, can be used independently from the machine to assess the correctness of CSP controllers developed to detail the control behaviour.

Advanced Lithography continues to be the limiting factor in the drive for higher levels of microcircuit integration. The key to the successful management of a lithography process is the integration of full measurement and instrumentation functions with the process, and the adoption of effective process control strategies. The aim of this research is to improve the understanding of critical dimension (CD) control by an investigation of the sources of variations in linewidth dimensions. Having identified the key factors, it should be possible to characterize and control their influence. Experime

By comparison other resources industries have lower fatality rates because of their focus on identifying the controls and verification activities

The chance of a component failure resulting in non-operation of the drive can be dramatically reduced by adopting a fault tolerant design. A fault tolerant drive must continue to operate throughout the occurrence of any single point failure without undue disturbance to the power output. Thereafter the dri

Their popularity and complexity are growing exponentially, giving birth to new, previously unexplored, safety-critical application domains. As CPS permeate our daily lives, it becomes imperative to reason about their reliability. Formal methods provide rigorous techniques for verification, control and synthesis of safe and reliable CPS. However, these methods do not scale with the complexity of the system, thus their applicability to real-world problems is limited. A promising strategy is to le

Abstract:
This work is an analysis of critical random Boolean networks used as control software for robots. The main goal is to find if there are relations between information theory measures on robot's sensors and actuators and the capability of the robot to achieve a particular task. Secondary goals are to verify if just the number of nodes of the networks is significant to obtain better populations of controllers for a given task and if a Boolean network can perform well in more than one single task. Results show that for certain tasks there is a strongly positively correlation between some informati
