A model for the consolidation of hybrid textiles considering air entrapment, dissolution and diffusion

Véronique Michaud, Vincent Werlen

A new model is proposed for the consolidation of hybrid textiles, in which air entrapment and dissolution are considered. One of the key parameters is tow permeability, which is described by the analytical model of Gebart and validated at very high fibre v ...

As easy as ABC: Optimal (A)ccountable (B)yzantine (C)onsensus is easy!

Rachid Guerraoui, Vincent Gramoli, Seth Gilbert, Jovan Komatovic, Pierre Philippe Civit

In a non-synchronous system with n processes, no t(0)-resilient (deterministic or probabilistic) Byzantine consensus protocol can prevent a disagreement among correct processes if the number of faulty processes is > n - 2t(0). Therefore, the community defi ...

Increasing Superstructure Optimization Capacity Through Self-Learning Surrogate Models

François Maréchal, Ivan Daniel Kantor, Julia Granacher

Simulation-based optimization models are widely applied to find optimal operating conditions of processes. Often, computational challenges arise from model complexity, making the generation of reliable design solutions difficult. We propose an algorithm fo ...

Optimizing the trade-off between performance measures and operational risk in a food supply chain environment

Philippe Wieser, Nicolas Zufferey, Simone Lydia Voldrich

In the context of a growing world population and the need to use limited resources responsibly, this study is motivated by the increasing pressures on the food industry, which include issues of food security, safety, and waste. In the context of a global f ...

Performance analysis of frequency shift estimation techniques in Brillouin distributed fiber sensors

Luc Thévenaz, Zhisheng Yang

The performance of post-processing techniques carried out on the Brillouin gain spectrum to estimate the Brillouin frequency shift (BFS) in standard Brillouin distributed sensors is evaluated. Curve fitting methods with standard functions such as polynomia ...

A Query Model to Capture Event Pattern Matching in RDF Stream Processing Query Languages

Jean Paul Calbimonte Perez

The current state of the art in RDF Stream Processing (RSP) proposes several models and implementations to combine Semantic Web technologies with Data Stream Management System (DSMS) operators like windows. Meanwhile, only a few solutions combine Semantic ...

TripleWave: Spreading RDF Streams on the Web

Karl Aberer, Jean Paul Calbimonte Perez

Processing data streams is increasingly gaining momentum, given the need to process these flows of information in real-time and at Web scale. In this context, RDF Stream Processing (RSP) and Stream Reasoning (SR) have emerged as solutions to combine semant ...

Life Cycle Analysis within Pharmaceutical Process Optimization and Intensification: Case Study of Active Pharmaceutical Ingredient Production

Lioubov Kiwi, Charline Berguerand

As the demand for new drugs is rising, the pharmaceutical industry faces the quest of shortening development time, and thus, reducing the time to market. Environmental aspects typically still play a minor role within the early phase of process development. ...

Towards Ontology-based Context Modeling for Manufacturing Applications

Drazen Nadoveza

Relevant and readily available information is a crucial basis for decision making, problem solving or performing knowledge-intensive work. The motivation for this thesis lays in the fact that in certain situations not all information provided by an applica ...

Mutation of the BAFF furin cleavage site impairs B-cell homeostasis and antibody responses

Friedrich Beermann

B-cell-activating factor of the TNF family (BAFF)/BLyS contributes to B-cell homeostasis and function in the periphery. BAFF is expressed as a membrane-bound protein or released by proteolytic cleavage, but the functional importance of this processing even ...

High-Performance Transactional Event Processing

Rachid Guerraoui, Jesper Honig Spring

This paper presents a transactional framework for low-latency, high-performance, concurrent event processing in Java. At the heart of our framework lies Reﬂexes, a restricted programming model for highly responsive systems. A Reﬂex task is an event process ...

An implementing framework for holonic manufacturing control with multiple robot-vision stations

The paper describes a holonic control architecture and implementing issues for agile job shop assembly with networked intelligent robots, based on the dynamic simulation of material processing and transportation. The holarchy was defined considering the PR ...

Batch process optimization via run-to-run constraints adaptation

Dominique Bonvin, Benoît Chachuat, Alejandro Gabriel Marchetti

In the batch process industry, the available models carry a large amount of uncertainty and can seldom be used to directly optimize real processes. Several measurement-based optimization methods have been proposed to deal with model mismatch and process di ...

Large scale selective event dissemination

Sidath Handurukande

Event-based systems usually denote distributed infrastructures that are used to asynchronously disseminate information among geographically distant computing units. In these systems, the information sources (a.k.a. publishers) produce events and the system ...

Capturing Design Rationale with Functional Decomposition of Roles in Business Processes Modeling

Alain Wegmann, Pavel Balabko

Enterprises need to create and maintain the fit between their business processes and their business process support (BPS) systems. This frequently requires re-engineering of business processes. If the business processes design ration-ales are made explicit ...

Separating Business Process from User Interaction in Web-Based Information Commerce

Karl Aberer, Anwitaman Datta, Zoran Despotovic

In Web-based information commerce it is diffcult to disentangle presentation from process logic, and sometimes even data is not separate from the presentation. Consequently, it becomes crucial to define an abstract model for business processes and their ma ...
