Verification of Programs with Pointers Based on Pattern Detection
Kubíček, Jan ; Erlebach, Pavel (referee) ; Vojnar, Tomáš (advisor)
This paper presents our results in study of verifiaction of infinite state space systems. We deal more concretely with abstract model checking. As main part of study we learned about pattern-based verification. This method is supposed to verify programs with dynamic memory structures like lists. Those structures are presented as directed graph. Pattern-based verifiaction abstracts any number of nodes by replacing them with summarized node. This way we achieve bounded  presentation of unbounded memory structure. Afterwards, verification is very effective due to low number of possible memory configurations. In our own work we deal with making model of a program for a tool that implements pattern-based verification. This model isconstructed from a subset of the C language. The main contribution of work is making the verification of simple programs written in C language completely self-acting by automation of constructing input model. In this paper wepresent the grammar of created subset of the C language and implementation details of translation.
Design Semiotics: Product design as a selective process of materialization Case study: Designers as the creators of materialized representations
Dostálová, Zuzana ; Řehořová, Irena (advisor) ; Váša, Ondřej (referee)
This paper deals with design semiotics, focuses on product design (light design) from the perspectives of social semiotics (van Leeuwen, 2005; Kress a van Leeuwen, 2006), multimodality (Kress, 2010) and product design (Norman, 1988, 2004a; Monö, 1997), and perceive design as a multimodal process of choices as well as a result of materialization of meanings. The theoretical chapters are dedicated to definitions of particular approaches and terms, which are applied within the empirical parts afterwards. These rely on the theories mentioned above and the design phases established by Riley (2003, 2004), which we linked with given theoretical approaches (the discourse phase with social semiotics; the conception phase with multimodality and emotional design; the inception phase with multimodality; and the reception phase with social semiotics and product design). Semi-structured interviews were held with three designers engaged in light design - Jan Plecháč, Jakub Pollág and Karel Matějka. The purpose of this paper is to explore and compare practices of designers from their own perspectives, considering intended product meanings (purposes), used modes and highlighting different design levels. Key words Social semiotics, product design, emotional design, multimodality, materialization
