The current practice of software architecture modeling and analysis would benefit of using different architectural languages, each specialized on a particular view and each enabling specific analysis. Thus, it is fundamental to pursue architectural language interoperability. An approach for enabling interoperability consists in defining a transformation from each single notation to a pivot lang...

In this paper, we first carry out an investigation on two existing pivot strategies for statistical machine transliteration, namely system-based and model-based strategies, to figure out the reason why the previous model-based strategy performs much worse than the system-based one. We then propose a joint alignment algorithm to optimize transliteration alignments jointly across source, pivot an...

We experimentally test competing theories of three-player majoritarian bargaining models with fixed, known reservation values. Subjects are randomly assigned to three roles: a proposer and two types of voters. Each role is randomly assigned a reservation value, i.e. a given amount of money he/she will receive if the proposal is rejected. These values are known to all players. Proposers then can...

This paper introduces a new shortest path simplex pivot rule choosing a subset of non-basic arcs to simultaneously enter into the basis. The term multiple pivot for this operation is used. From this concept, a generic shortest path simplex algorithm with multiple pivots is described. In addition, a simplex multiple pivot rule is provided to design a shortest path simplex algorithm requiring O(n...

Image collections are a tremendous source of information. Yet due to the semantic gap it is difficult to get access to their content, while at the same time it is difficult to properly employ their context such as tags and metadata. To move forward we propose a multimedia analytics solution. The most widespread and universally used analytic tools are spreadsheets, where a powerful feature is th...

This paper considers the problem of damping the oscillation of a plane pendulum by moving the pivot in the vertical plane and the weight along the rod of the pendulum, with limited amplitudes. Conditions for stability of the motion of the pendulum are derived using energybased methods, and based on them energy-based controls satisfying the amplitude constraints are developed, which move the piv...

Extensions of the Schur complement and the principal pivot transform, where the usual inverses are replaced by the Moore-Penrose inverse, are revisited. These are called the pseudo Schur complement and the pseudo principal pivot transform, respectively. First, a generalization of the characterization of a block matrix to be an M -matrix is extended to the nonnegativity of the Moore-Penrose inve...
