Coalgebraic semantics for timed processes [PDF]

open access: yes, 2006
We give a coalgebraic formulation of timed processes and their operational semantics. We model time by a monoid called a “time domain”, and we model processes by “timed transition systems”, which amount to partial monoid actions of the time domain or ...

Estrus Synchronization and Pregnancy Rate Using Ovsynch Method in Uganda Dairy Farms

open access: yesJournal of Animal Reproduction and Biotechnology, 2017
The artificial insemination (AI) is one of the best assisted reproductive technologies for increasing reproductive capacity and facilitating the genetic improvement in farm animals.

Performance analysis of probabilistic timed automata using digital clocks [PDF]

open access: yes, 2006
Probabilistic timed automata, a variant of timed automata extended with discrete probability distributions, is a modelling formalism suitable for describing formally both nondeterministic and probabilistic aspects of real-time systems, and is amenable to

Timed Runtime Monitoring for Multiparty Conversations [PDF]

open access: yes, 2014
We propose a dynamic verification framework for protocols in real-time distributed systems. The framework is based on Scribble, a tool-chain for design and verification of choreographies based on multiparty session types, developed with our industrial ...

Model Checking Timed Automata with Priorities using DBM Subtraction

open access: yes, 2006
In this paper we describe an extension of timed automata with priorities, and efficient algorithms to compute subtraction on DBMs (difference bounded matrices), needed in symbolic model-checking of timed automata with priorities.

Efficient Detection of Zeno Runs in Timed Automata [PDF]

open access: yes, 2007
Zeno runs, where infinitely many actions occur in finite time, may inadvertently arise in timed automata specifications. Zeno runs may compromise the reliability of formal verification, and few model-checkers provide the means to deal with them: this ...

Evaluation of a modified GnRH-based timed-AI protocol associated with estrus detection in beef heifers inseminated with sex-selected or conventional semen.

open access: yesTheriogenology, 2018
The main objective was to compare pregnancy per AI (P/AI) between sex-selected and conventional semen in cyclic beef heifers subjected to a 5-day Co-synch plus CIDR protocol and evaluated the usefulness of an estrus detection (ED) aid to identify heifers

COWS: A Timed Service-Oriented Calculus [PDF]

open access: yes, 2007
COWS (Calculus for Orchestration of Web Services) is a foundational language for Service Oriented Computing that combines in an original way a number of ingredients borrowed from well-known process calculi, e.g.

Field comparison of GnRH and PGF2α treatments in cows not expressing estrus at timed-AI [PDF]

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia
RESUMO Objetivou-se comparar as taxas de prenhez (TP) e a perda gestacional (PG) de vacas sem expressão de estro (NEE), as quais receberam PGF2α ou GnRH no momento da IATF.

Reproductive performance of early- and late-calving dairy cows artificially inseminated after ovulation synchronization and estrous resynchronization or artificially inseminated after observed estrus

open access: yesJDS Communications, 2021
Within seasonal dairy systems, cows that calve late in the calving season are less likely to become pregnant and maintain a yearly calving interval. Very few studies have examined effective strategies for reproductive management of these late-calving ...
