Abstract
In order to develop an hybrid approach to the Reverse Engineer of Web applications, we need first to understand how much of the control logic of the user interface can be obtained from the analysis of event listeners. To that end, we have developed a tool that enables us to perform such analysis, and applied it to the implementation of the one thousand most widely used Websites (according to Alexa Top Sites). This paper describes our approach for analyzing the user interface layer of those Websites, and the results we got from the analysis. The conclusions drawn from the exercise will be used to guide the development of the proposed hybrid reverse engineering tool.

Abstract
Safe operation of safety critical systems depends on appropriate interactions between the human operator and the computer system. Specification of such safety-critical systems is fundamental to enable exhaustive and automated analysis of operator system interaction. In this paper we present a structured, comprehensive and computer-aided approach to formally specify and verify user interfaces based on model checking techniques.

Abstract
In the domain of machines' design, one of the most important issues to solve is related with the controller's design, mainly, guaranteeing that the machine will behave as expected. In order to achieve a dependable controller, some steps can be considered, such as the formalization of its specification-before being translated to the program that will be inserted in the controller device-and the respective analysis and verification. Nowadays, some formal analysis techniques, such as formal verification, are used to achieve this purpose. The dependability of a controller, however, is impacted by its execution context. This paper proposes an approach for the formal verification of the specification of mechatronic system's controllers, which considers, on the formal verification tasks, the behavior of the plant and the behavior of the Human Machine Interface of the Mechatronic system. Some conclusions are extrapolated for other systems of the same kind.

Abstract
.Abstract algebra has the power to unify seemingly disparate theories once they are encoded into the same abstract formalism. This paper shows how a relation-algebraic rendering of both database dependency theory and Hoare programming logic purports one such unification, in spite of the latter being an algorithmic theory and the former a data theory. The approach equips relational data with functional types and an associated type system which is useful for database operation type checking and optimization. The prospect of a generic, unified approach to both programming and data theories on top of libraries already available in automated deduction systems is envisaged.
