Service opportunities for next generation networks

Next Generation Networks was the buzzword last year. Different people imagine different things when they think of NGN. How can this concept be defined? NGN is the application of Internet, IP and IT solutions to Telecom Services, including (but not only) the integration and sometimes the substitution of circuit switching with packet switching either for trunking or for access. Surprisingly, usually people think of a mere porting of Telecom protocols over an IP network (read H.323 protocol). Why should we reuse existing telecom solutions over an IP transport? The usual answer is to reduce cost of ownership. Is that really true? Is that a reason enough? Indeed, the introduction of NGN opens a huge opportunity for incumbent telecom operators: enabling the renewal in the service offering (meaning cash!) In this paper, we present the objectives and results of the Eurescom Project P1109”Next Generation Networks: the service offering Standpoint”. The overall goal is to evaluate solutions for NGNs from a service-offering standpoint and understanding the wider effects of introducing NGNs both in a fixed and 3G mobile network infrastructure, in terms of the inter-operability and functionality of next generation network products. In particular this paper focuses on the implementation of service scenarios (i.e. call center, VPN) on top of NGN platforms. The implementation of the service scenarios is meant to measure the attitude of NGN service platforms to provide new services in a developer friendly way

Carving from Ray-Tracing Constraints: IRT-Carving

We present a new algorithm for improving an available (conservative) estimate of the shape of an object using constraints from ray-tracing. In particular, we exploit incoherences between the lit portions of the object - detected on a set of acquired images - and the shadows that the current estimate casts on itself. Whenever a contradiction is found the current estimate is modified in order to remove the inconsistency. Sufficient conditions for the correctness of the algorithm and a discussion of their validity are provided. Finally, we describe a simple implementation of the method and present some preliminary experimental results from computer simulations

Next Generation Networks: the service offering standpoint

Next Generation Networks (NGN) is the application of Internet, IP and IT solutions to Telecom Services, including (but not only) the integration and sometimes the substitution of circuit switching with packet switching either for trunking or for access. In this paper, we will present the objectives and results of the Eurescom Project P1109 [1]. The overall goal is to support this view, in evaluating solutions for NGNs from a service-offering standpoint and understanding the wider effects of introducing NGNs in terms of the inter-operability and functionality of NGN products

Imaging of the Inner Zone of Blast Furnaces Using MuonRadiography: The BLEMAB Project

The aim of the BLEMAB project (BLast furnace stack density Estimation through online Muons ABsorption measurements) is the application of muon radiography techniques, to image a blast furnace’s inner zone. In particular, the goal of the study is to characterize the geometry and size of the so-called “cohesive zone”, i.e., the spatial region where the slowly downward-moving material begins to soften and melt, which plays such an important role in the performance of the blast furnace itself. Thanks to the high penetration power of natural cosmic-ray muon radiation, muon transmission radiography could be an appropriate non invasive methodology for the imaging of large high-density structures such as a blast furnace, whose linear dimensions can be up to a few tens of meters. A state-of-the-art muon tracking system is currently in development and will be installed at a blast furnace on the ArcelorMittal site in Bremen (Germany), where it will collect data for a period of various months. In this paper, the status of the project and the expectations based on preliminary simulations are presented and briefly discussed

The BLEMAB European project: Muon radiography as an imaging tool in the industrial field

The European project called BLEMAB (BLast furnace stack density Estimation through on-line Muons ABsorption measurements), provides for the application of the muon radiography technique in the industrial environment. The project represents a non-invasive way of monitoring a blast furnace and in particular aims to study the geometric and density development of the so-called “cohesive zone”, which is important for the performance of the blast furnace itself. The installation of the detectors is expected in 2022 at the ArcelorMittal site in Bremen (Germany). This paper describes the status of the project, the experimental setup and the first results obtained with preliminary simulations. © 2022 Societa Italiana di Fisica. All rights reserved

West-Life: A Virtual Research Environment for structural biology

The West-Life project (https://about.west-life.eu/)is a Horizon 2020 project funded by the European Commission to provide data processing and data management services for the international community of structural biologists, and in particular to support integrative experimental approaches within the field of structural biology. It has developed enhancements to existing web services for structure solution and analysis, created new pipelines to link these services into more complex higher-level workflows, and added new data management facilities. Through this work it has striven to make the benefits of European e-Infrastructures more accessible to life-science researchers in general and structural biologists in particular

Towards a muon collider

A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity and 10 TeV centre of mass energy are being investigated by the recently-formed International Muon Collider Collaboration. This Review summarises the status and the recent advances on muon colliders design, physics and detector studies. The aim is to provide a global perspective of the field and to outline directions for future work
