Physics-Informed Machine Learning for Modeling and Control of Dynamical Systems

Colin Neil Jones, Melanie Nicole Zeilinger, Roland Schwan, Xuan Truong Nghiem

Physics-informed machine learning (PIML) is a set of methods and tools that systematically integrate machine learning (ML) algorithms with physical constraints and abstract mathematical models developed in scientific and engineering domains. As opposed to ...

A Noise-Resistant Mixed-Discrete Particle Swarm Optimization Algorithm for the Automatic Design of Robotic Controllers

Alcherio Martinoli, Cyrill Silvan Baumann

The automatic design of well-performing robotic controllers is still an unsolved problem due to the inherently large parameter space and noisy, often hard-to-define performance metrics, especially when sequential tasks need to be accomplished. Distal contr ...

Replicated state machines without replicated execution

Kirill Nikitin

This paper introduces a new approach to reduce end-to-end costs in large-scale replicated systems built under a Byzantine fault model. Specifically, our approach transforms a given replicated state machine (RSM) to another RSM where nodes incur lower costs ...

Drowsy-DC: Data center power management system

Willy Zwaenepoel, Baptiste Joseph Eustache Lepers

In a modern data center (DC), a large majority of costs arise from energy consumption. The most popular technique used to mitigate this issue is virtualization and more precisely virtual machine (VM) consolidation. Although consolidation may increase serve ...

Computing Crowd Consensus with Partial Agreement (Extended Abstract)

Quoc Viet Hung Nguyen, Thành Tâm Nguyên

Crowdsourcing has been widely established as a means to enable human computation at large-scale, in particular for tasks that require manual labelling of large sets of data items. Answers obtained from heterogeneous crowd workers are aggregated to obtain a ...

Verification of Component-based Systems via Predicate Abstraction and Simultaneous Set Reduction

Simon Bliudze, Qiang Wang

This paper presents a novel safety property verification approach for component-based systems modelled in BIP (Behaviour, Interaction and Priority), encompassing multiparty synchronisation with data transfer and priority. Our contributions consist of: (1 ...

The S2E Platform: Design, Implementation, and Applications

George Candea, Vitaly Chipounov, Volodymyr Kuznetsov

This article presents S2E, a platform for analyzing the properties and behavior of software systems, along with its use in developing tools for comprehensive performance profiling, reverse engineering of proprietary software, and automated testing of kerne ...

Scala to the Power of Z3: Integrating SMT and Programming

Viktor Kuncak, Philippe Paul Henri Suter

We describe a system that integrates the SMT solver Z3 with the Scala programming language. The system supports the use of the SMT solver for checking satisfiability, unsatisfiability, as well as solution enumeration. The embedding of formula trees into Sc ...

A General Characterization of Indulgence

Rachid Guerraoui

An indulgent algorithm is a distributed algorithm that, besides tolerating process failures, also tolerates unreliable information about the interleaving of the processes. This article presents a general characterization of indulgence in an abstract comput ...

A mealy machine with polynomial growth of irrational degree

We consider a very simple Mealy machine ( two nontrivial states over a two-symbol alphabet), and derive some properties of the semigroup it generates. It is an infinite, finitely generated semigroup, and we show that the growth function of its balls behave ...

Correctly defined concrete syntax

Due to their complexity, the syntax of modern modeling languages is preferably defined in two steps. The abstract syntax identifies all modeling concepts whereas the concrete syntax should clarify how these concepts are rendered by graphical and/or textual ...

Concrete syntax definition for modeling languages

Frédéric Fondement

Model Driven Engineering (MDE) promotes the use of models as primary artefacts of a software development process, as an attempt to handle complexity through abstraction, e.g. to cope with the evolution of execution platforms. MDE follows a stepwise approac ...

A Method of Functional Alignment Verification in Hierarchical Enterprise Models

Alain Wegmann

Enterprise modeling involves multiple domains of expertise: requirements engineering, business process modeling, IT development etc. Our experience has shown that hierarchical enterprise models, made of an assembly of system models, are effective. In these ...

On the Usage of Concrete Syntax in Model Transformation Rules

Graph transformations are one of the best known approaches for defining transformations in model-based software development. They are defined over the abstract syntax of source and target languages, described by metamodels. Since graph transformations are ...

Correctly Defined Concrete Syntax for Visual Modeling Languages

The syntax of modeling languages is usually defined in two steps. The abstract syntax identifies modeling concepts whereas the concrete syntax clarifies how these modeling concepts are rendered by visual and/or textual elements. While the abstract syntax i ...
