Our review of the MeTag app and MeTagAnalyze web is based on an initial test project involving undergraduate students, and, later, its adoption as part a mixed-methods longitudinal research datafication childhood family life. We contextualise value media diaries tool in phenomenological user-centred traditions, namely Domestication Technology approach constructivist mediatization tradition. Bas...

The characteristics of users' browsing behaviors on websites can be used to analyze system performance as well as network communication, understand users’ reaction and motivation, and build adaptive websites. However, the motivation, requirement and experience of users may dynamically change, which cause difficulty in exactly refining a stable behavior pattern and describing their shifted inter...

We analyze random networks that change over time. First we analyze a dynamic Erdős-Renyi model, whose edges change over time. We describe its stationary distribution, its convergence thereto, and the SI contact process on the network, which has relevance for connectivity and the spread of infections. Second, we analyze the effect of node turnover, when nodes enter and leave the network, which h...

Dynamic graphs are useful objects to describe a network which evolves over time. We propose a signal theory approach to analyze them which consists of transforming the graph at each time step into a collection of signals and analyze these signals using spectral decomposition. An inverse transformation is also proposed and makes it possible to reduce the dimension of the graph and select the mos...

A dynamic game-based model of electronic payment systems is proposed, which is used to analyze formally security property of electronic payment protocols. Compared with previous work, the main contributions are as follows. Firstly, using strategic games to model channels in three kinds of qualities and participants of dishonest behaviors makes it able to analyze cooperative and adversarial beha...

Abstract. This paper presents a synthesis method for generating true single-clock dynamic CMOS flip-flops. Such dynamic circuits are used today for very high performance microprocessors and ASICs, however with some supplementary keeper transistors. Many references [1, 11, 12, 13, 16, 17, 20, 22] have presented dynamic single-phase clock latches and flip-flops, however without a corresponding sy...
