Abstract:
<p>In the system identification community a popular framework for the problem of estimating a parametrized model structure given a sequence of input and output pairs is given by the prediction-error method. This method tries to find the parameters which maximize the prediction capability of the corresponding model via the minimization of some chosen cost function that depends on the prediction error. This optimization problem is often quite complex with several local minima and is commonly solved using a local search algorithm. Thus, it is important to find a good initial estimate for the loca

Abstract:
<p>Two main types of formal methods have been investigated, formal specification and formal verification. Focus for formal verification has been on the concept of un-timed model checking. Some dominating formal specification languages, VDM and Z, and some prominent model checkers, FDR, Spin, and LTSA, have been learnt and presented. A tutorial for the formal verification tool Spin is created. The tutorial is example driven and describes the description language Promela and the verification methods available in Spin. Care has been taken to illustrate reasoning about the results from Spin. Top

Abstract:
The extensive use of a least-squares problem formulation in many fields is partly motivated by the existence of an analytic solution formula which makes the theory comprehensible and readily applicable, but also easily embedded in computer-aided design or analysis tools. While the mathematics behind convex optimization has been studied for about a century, several recent researches have stimulated a new interest in the topic. Convex optimization, being a special class of mathematical optimization problems, can be considered as generalization of both least-squares and linear programming. As in

<p>To simplify troubleshooting and reliability of a process, a diagnosis system can supervise the process and alarm if any faults are detected. A diagnosis system can also identify one, or several faults, i.e. isolate faults, that may have caused the alarm. If model-based diagnosis is used, tests based on observations from the process are compared to a model of the process to diagnose the process. It can be a hard task to find which tests to be used for maximal fault detection and fault isolation. Structural Methods require not very detailed knowledge of the process to be diagnosed and can be

It is widely believed that a major reason for
