Analysis of Sequential Caputo Fractional Differential Equations versus Non-Sequential Caputo Fractional Differential Equations with Applications

open access: yesFoundations, 2022
It is known that, from a modeling point of view, fractional dynamic equations are more suitable compared to integer derivative models. In fact, a fractional dynamic equation is referred to as an equation with memory.

Semantics through Pictures [PDF]

open access: yes, 1997
A diagrammatic approach to the semantics of OO modelling notations is proposed. This is based on an innovative and expressive notation dubbed ''constraint diagrams'', which can be used to precisely characterise a range of sophisticated, static ...

Noninvasive monitoring of radiotherapy-induced microvascular changes using dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) in a colorectal tumor model [PDF]

open access: yes, 2006
To examine dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) with a macromolecular contrast agent (P792) to visualize effects of radiotherapy (RT) on microvascular leakage in a colorectal cancer model.Journal Articleinfo:eu-repo/semantics ...

A formal dynamic semantics of Java: an essential ingredient of Java security

open access: yesJournal of Telecommunications and Information Technology, 2002
Security is becoming a major issue in our highly networked and computerized era. Malicious code detection is an essential step towards securing the execution of applications in a highly inter-connected context.

Hybrid Semantics of Stochastic Programs with Dynamic Reconfiguration [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2009
We begin by reviewing a technique to approximate the dynamics of stochastic programs --written in a stochastic process algebra-- by a hybrid system, suitable to capture a mixed discrete/continuous evolution.

Context updates are hierarchical

open access: yesGlossa, 2016
This squib studies the order in which elements are added to the shared context of interlocutors in a conversation. It focuses on context updates within one hierarchical structure and argues that structurally higher elements are entered into the context ...

Flow Control around the UAS-S45 Pitching Airfoil Using a Dynamically Morphing Leading Edge (DMLE): A Numerical Study

open access: yesBiomimetics, 2023
This paper investigates the effect of the Dynamically Morphing Leading Edge (DMLE) on the flow structure and the behavior of dynamic stall vortices around a pitching UAS-S45 airfoil with the objective of controlling the dynamic stall.

Dynamic structural operational semantics

open access: yesJournal of Logical and Algebraic Methods in Programming, 2019
We introduce Dynamic SOS as a framework for describing semantics of programming languages that include dynamic software upgrades, for upgrading software code during run-time. Dynamic SOS (DSOS) is built on top of the Modular SOS of P. Mosses, with an underlying category theory formalization.

Regulating Data Exchange in Service Oriented Applications [PDF]

open access: yes, 2007
We define a type system for COWS, a formalism for specifying and combining services, while modelling their dynamic behaviour. Our types permit to express policies constraining data exchanges in terms of sets of service partner names attachable to each ...

Explaining presupposition projection with dynamic semantics

open access: yesSemantics and Pragmatics, 2011
Heim's (1982, 1983b) dynamic semantics provides an attractive system for capturing the basic facts about presupposition projection. A long-standing criticism of this semantics is that it requires for each connective lexical stipulations that are not ...
