Real-time specifications [PDF]

International Journal on Software Tools for Technology Transfer, 2013
A specification theory combines notions of specifications and implementations with a satisfaction relation, a refinement relation, and a set of operators supporting stepwise design. We develop a specification framework for real-time systems using Timed I/O Automata as the specification formalism, with the semantics expressed in terms of Timed I/O ...

Quantitative Measurements of Codeine and Fentanyl on a Surface-Enhanced Raman-Active Pad

Molecules, 2019
The USA is in the midst of an opioid crisis that included over 60,000 overdose fatalities in 2017, mostly unintentional. This is due to excessive use of prescription opioids and the use of very strong synthetic opioids, such as fentanyl, mixed with ...

Dynamic scheduling of parallel real-time jobs by modelling spare capabilities in heterogeneous clusters [PDF]

, 2003
In this research, a scenario is assumed where periodic real-time jobs are being run on a heterogeneous cluster of computers, and new aperiodic parallel real-time jobs' modelled by Directed Acyclic Graphs (DAG), arrive at the system dynamically.
