This paper provides a concise summary of the framework of operational-probabilistic theories, aimed at emphasizing the interaction between category-theoretic and probabilistic structures. Within this framework, we review an operational version of the GNS construction, expressed by the so-called purification principle [12], which under mild hypotheses leads to an operational version of Stinespri...

This paper present a semantic model of an higher-order process calculus that can be interactively updated by the user to handle locality information. We hide locations at the calculus level in an aspect-oriented programming style. This separation of concerns helps programmers designing pure functional components while delaying the management of lower level and orthogonal details such as allocat...

We consider the calculus of Communicating Sequential Processes (CSP) [8] extended with action-guarded probabilistic choice and provide it with an operational semantics in terms of a suitable extension of Larsen and Skou’s [14] reactive probabilistic transition systems. We show that a testing equivalence which identifies two processes if they pass all tests with the same probability is a congrue...

We proposed a syntactical format, the path format, for structured operational semantics in which predicates may occur. We proved that strong bisim-ulation is a congruence for all the operators that can be deened within the path format. To show that this format is useful we provided many examples that we took from the literature about CCS, CSP, and ACP; they do satisfy the path format but no for...

A polypropylene microporous membrane (PPMM) was fabricated by thermally induced phase separation (TIPS) method. The effects of protein size and structure as well as filtration pressure on the membrane performance and fouling mechanisms were investigated using two different proteins, bovine serum albumin (BSA) and collagen, in dead-end filtration setup. Obtained results showed that, for each pro...

We introduce a general stochastic process operator f d:D p(d) which behaves as the process p(d) where the value d is chosen from a data domain D with a probability density determined by f . We require that f is a measurable function from D to R such that R d∈D f(d)dμD = 1. For finite or countable D the function f represents the probability distribution directly. For bigger domains f represents ...

joule-thomson cooling systems are used in refrigeration processes such as cryogenic gas liquefaction. although extensive studies have been carried out by researchers, most of them include cryogenic heat exchangers and their associated fields. in the current study, an attempt was made to indicate the effect of using inappropriate operational conditions in a cryogenic joule-thomson cooling system...

The Parameterised Model Checking Problem asks whether an implementation Impl(t) satisfies a specification Spec(t) for all instantiations of parameter t . In general, t can determine numerous entities: the number of processes used in a network, the type of data, the capacities of buffers, etc. The main theme of this paper is automation of uniform verification of a subclass of PMCP with the param...

The specification and simulation of complex concurrent systems is a difficult task due to the intricate combinations of message passing and synchronizations that can occur between the components of the system. Two of the most extended formalisms used to specify, verify and simulate such kind of systems are CSP and the Petri nets. This work introduces a new technique that allows us to automatica...

Compensation is a technique to roll-back a system to a consistent state in case of failure. Recovery mechanisms for compensating calculi specify the order of execution of compensation sequences. Dynamic recovery means that the order of execution is determined at runtime. In this paper, we define an extension of Compensating CSP, called DEcCSP, with general dynamic recovery. We provide a formal,...
