LSOM: A Link State protocol Over MAC addresses for metropolitan backbones using Optical Ethernet switches
2003
This paper presents a new protocol named "Link State Over MAC" (LSOM) for Optical Ethernet switches to allow the use of active loop topologies, like meshes, in Metropolitan Area Networks (MAN) or even Wide Area Networks (WAN) backbone. In this respect, LSOM is an alternative to a ring topology as proposed in draft IEEE 802.17 Resilient Packet Ring (RPR) or a tree topology using IEEE802. 1D Rapid Spanning Tree Protocol (RSTP). LSOM provides higher scalability and is able to achieve better bandwidth utilization and lower latency than RSTP and RPR. Simulation results for 4-node and 9-node topologies show that LSOM can improve throughput over RPR by a factor of up to 1.7. Furthermore, full free…
ZERO: An Efficient Ethernet-Over-IP Tunneling Protocol
2013
An Ethernet over IPv4 tunneling protocol is proposed, which categorizes all Ethernet frames to be tunneled into NICE and UGLY frames. The UGLY frames are tunneled by traditional methods, such as UDP or GRE encapsulation, resulting in substantial overhead due to additional headers and fragmentation usually required to transport long Ethernet frames over IP network typically limited to MTU=1,500 bytes. Meanwhile the NICE Ethernet frames are tunneled without any overhead as plain IPv4 packets due to non-traditional reuse of “fragment offset” or “identification” field in the IP header. It is shown that for typical Internet traffic transported over Ethernet, the proposed ZERO tunneling protocol …
Barriers to Sport Participation Faced by Ethiopian and Eritrean Migrant Women in Switzerland
2021
Global migration (both forced and voluntary) has intensified the interaction between existing and emerging cultures. Sport has gained recognition as an effective tool for enhancing migrants’ overall wellbeing, active participation, and social integration. However, a growing number of studies have shown that migrant women have the lowest rate of sport participation, especially in organized clubs. These findings have brought the accessibility and inclusion of existing sport structure and culture in host countries into question. Using the six-factor model of constraints by Tsai and Coleman (1999), this study explored the barriers that hinder Ethiopian and Eritrea migrant women (EEMW) from part…

Forecasting : theory and practice
2022
Forecasting has always been at the forefront of decision making and planning. The uncertainty that surrounds the future is both exciting and challenging, with individuals and organisations seeking to minimise risks and maximise utilities. The large number of forecasting applications calls for a diverse set of forecasting methods to tackle real-life challenges. This article provides a non-systematic review of the theory and the practice of forecasting. We provide an overview of a wide range of theoretical, state-of-the-art models, methods, principles, and approaches to prepare, produce, organise, and evaluate forecasts. We then demonstrate how such theoretical concepts are applied in a varie…
Transient dynamics of pulse-driven memristors in the presence of a stable fixed point
2019
Abstract Some memristors are quite interesting from the point of view of dynamical systems. When driven by narrow pulses of alternating polarities, their dynamics has a stable fixed point, which may be useful for future applications. We study the transient dynamics of two types of memristors characterized by a stable fixed point using a time-averaged evolution equation. Time-averaged trajectories of the Biolek window function memristor and resistor-threshold type memristor circuit (an effective memristor) are determined analytically, and the times of relaxation to the stable fixed point are found. Our analytical results are in perfect agreement with the results of numerical simulations.
Bifurcation analysis of a TaO memristor model
2019
This paper presents a study of bifurcation in the time-averaged dynamics of TaO memristors driven by narrow pulses of alternating polarities. The analysis, based on a physics-inspired model, focuses on the stable fixed points and on how these are affected by the pulse parameters. Our main finding is the identification of a driving regime when two stable fixed points exist simultaneously. To the best of our knowledge, such bistability is identified in a single memristor for the first time. This result can be readily tested experimentally, and is expected to be useful in future memristor circuit designs.
Highly selective chemical sensing in a luminescent nanoporous magnet.
2012
Among the wide variety of properties of interest that a given material can exhibit, luminescence is attracting an increasing attention due to its potential application in optical devices for lighting equipment and optical storage, [ 1a − c] optical switching, [ 1d ,e] and sensing. [ 1f − i ] At this respect, many scientists, working in the multidisciplinary fi eld of the materials science, have directed their efforts to the obtention of luminescent materials with potential sensing applications. For instance, sensitive and selective detection of gas and vapor phase analytes can result specially interesting because of the variety of applications that can be found in many different fi elds.

Korpora, Kombinatorik, Übersetzungssegmente… statt Terminologie? Zum neuen Stellenwert von Termini und Terminologie im Sprachtechnologie-Zeitalter am…
2021
International audience; Kontext Fachübersetzung sieht sich heute – vor dem Hintergrund der rasanten Entwicklung von Sprachtechnologien – vor neue Herausforderungen gestellt. Korpusbasierte Tools und Systeme wie Translation Memories, Konkordanzen, Maschinenübersetzung, … lenken die Aufmerksamkeit auf neue Übersetzungseinheiten, die – meistens als „Segmente“ aufgefasst – die traditionellen am Sprachsystem orientierten Kategorien – allen voran das Wort – neu beleuchten. Als auf die mehr oder weniger gelenkte Vermittlung von Fachinhalten ausgerichtete Tätigkeit bleibt aber Fachübersetzung nach wie vor sehr stark von terminologischen Fragestellungen geprägt, da das dem zu übersetzenden Text zu…
Fachsprachliche Konstruktionen? Zur korpuslinguistischen Neufundierung des Lexik-Grammatik-Kontinuums in stark formalisierten Fachtextsorten
2017
International audience; [Problemstellung und Thesen] Folgender Vorschlag reiht sich hauptsächlich in den ersten thematischen Strang des Calls für die Sektion ‚Grammatik und Grammatikographie’ ein, wobei die Forschungsergebnisse auch didaktisch, also für die „Entwicklung und Erstellung von Lernergrammatiken“ (2. Strang), verwertet werden können. Er geht der Frage nach dem Mehrwert korpuslinguistischer Instrumentarien für die Analyse von Fachtexten mit hohem Grad an Formelhaftigkeit nach. Der Beitrag vertritt folgende Thesen:a.Sind die linguistischen – auch morpho-syntaktischen – Merkmale von Fachtexten nicht qualitativer, sondern quantitativer Natur (Roelcke 20103), so können sie so gut wie …
