There are two well investigated approaches to automate reasoning in modal logics: the direct approach and the translational approach. The direct approach [6, 7, 14, 27] develops specific calculi and tools for the task; the translational approach [29, 30] transforms modal logic formulas into firstorder logic and applies standard first-order tools. Embeddings of modal logics into higher-order log...

In this paper, a timed modal logic Lc is presented for the specification and verification of real-time systems. Several important results for Lc are discussed. First we address the model checking problem and we show that it is an EXPTIMEcomplete problem. Secondly we consider expressiveness and we explain how to express strong timed bisimilarity and how to build characteristic formulas for timed...

Subtyping is a crucial ingredient of session type theory and its applications, notably to programming language implementations. In this paper, we study effective ways to check whether a session type is a subtype of another by applying a characteristic formulae approach to the problem. Our core contribution is an algorithm to generate a modal μ-calculus formula that characterises all the superty...

In this paper we work on (bi)simulation semantics of processes that exhibit both nondeterministic and probabilistic behaviour. We propose a probabilistic extension of the modal mu-calculus and show how to derive characteristic formulae for various simulation-like preorders over finite-state processes without divergence. In addition, we show that even without the fixpoint operators this probabil...

Shear-induced particle migration was investigated by using a continuum diffusive -flux model for the creep flow of nickel powder filled polymers, which are viscous with shear-thinning characteristic. The model, together with flow equations, was employed for solving the non-Newtonian flow patterns and non-uniform particle concentration distribution of mono-modal suspensions in a pressure-driven ...

This paper summarises recent work on vision based localisation of a moving camera using particle filtering. We are interested in real-time operation for applications in mobile and wearable computing, in which the camera is worn or held by a user. Specifically, we aim for localisation algorithms which are robust to the real-life motions associated with human activity and to the dynamic clutter e...

Karyawan memiliki tingkat stres tinggi dan berkepanjangan akan berniat meninggalkan karena modal psikologis, sosial manusia tangguh mampu menangani beban tuntutan pekerjaan. Tujuan dari studi ini adalah mengetahui keterkaitan antara sos...

The present study set out to investigate the effect of teaching substitution as a kind of grammatical cohesion on the true identification of confusing substitution elements with cohesive or non-cohesive roles in different contexts and also the production of modal, reporting and conditional contexts through clausal substitution acquaintance. To this end, the following procedures were taken. Firs...
