Mainz/PSI Φ-factory design considerations
1991
Abstract Design considerations for a Φ-factory with a Luminosity of the order of 10 33 cm −2 s −1 lead to the concept of a multi-bunch round beam double storage ring with supercoducting solenoids for micro-beta focusing and beam rotation. Simulations of the beam-beam-interaction indicate, that significantly higher beam-beam-parameters may become possible with round beams. A rough draft design of a round beam Φ-factory is presented.
IRIDE: Interdisciplinary research infrastructure based on dual electron linacs and lasers
2014
This paper describes the scientific aims and potentials as well as the preliminary technical design of RUDE, an innovative tool for multi-disciplinary investigations in a wide field of scientific, technological and industrial applications. IRIDE will be a high intensity "particles factory", based on a combination of high duty cycle radio-frequency superconducting electron linacs and of high energy lasers. Conceived to provide unique research possibilities for particle physics, for condensed matter physics, chemistry and material science, for structural biology and industrial applications, IRIDE will open completely new research possibilities and advance our knowledge in many branches of sci…
Analytical and Numerical Assessment of Thermally Induced Pressure Waves in the IFMIF-DONES Liquid-Lithium Target
2020
The intended steady-state operation conditions of the International Fusion Materials Irradiation Facility-DEMO Oriented Neutron Source (IFMIF-DONES) target system are based on the D+ beam stationary running at full nominal power (5 MW). Nevertheless, critical situations can occur in the case of unavoidable sudden events like beam trips. The instantaneous variation in the heating power deposited in lithium when the beam is rapidly switched between ON-and OFF-states leads to thermal expansion, which is compensated by the compression of the target material, resulting in locally high pressures and a pressure wave propagating through the target toward the back wall. Besides the tensile stress of…
Object Recognition and Modeling Using SIFT Features
2013
In this paper we present a technique for object recognition and modelling based on local image features matching. Given a complete set of views of an object the goal of our technique is the recognition of the same object in an image of a cluttered environment containing the object and an estimate of its pose. The method is based on visual modeling of objects from a multi-view representation of the object to recognize. The first step consists of creating object model, selecting a subset of the available views using SIFT descriptors to evaluate image similarity and relevance. The selected views are then assumed as the model of the object and we show that they can effectively be used to visual…
IP-OOP interaction in URM infilled frame structures: A new macro-modelling proposal
2020
Abstract Reinforced concrete frame structures with unreinforced masonry (URM) infills represent a common construction practice all over the world. To correctly assess the seismic performance of these structures, prediction of the behaviour of masonry infills under in-plane (IP) and out-of-plane (OOP) loading, as well as their interaction, is of primary importance. Different approaches are available in the literature with different levels of approximation for assessment of the IP-OOP infill response, showing increasing interest in this field. In this context, this paper presents a new macro-element model which can simulate the behaviour of URM infill walls under seismic IP and OOP actions. T…
The inheritance workshop
2002
International audience; The Inheritance Workshop at ECOOP 2002, which took place on Tuesday, 11 June, was the first ECOOP workshop focusing on inheritance after the successful workshops in 1991 and 1992. The workshop was intended as a forum for designers and implementers of object-oriented languages, and for software developers with an interest in inheritance. It was organized by Andrew P. Black, Erik Ernst, Peter Grogono, and Markku Sakkinen.
Mobile agents principles of operation
2004
Publisher Summary This chapter discusses the mobile agent technology and summarizes their features, principles of operation and implementation elements. Some development tools are also discussed. The chapter provides general description of mobile agents as an advanced software paradigm, which extends object oriented programming. Then it discusses principles of operation starting from agent intelligent behavior and continuing with mobility, communication, coordination, and fault tolerance. Finally, as for related topics, monitoring, performances, and security issues are discussed in the chapter. Agent monitoring techniques are very useful because they allow users to know which agents are run…

In the framework of function points associated to OO-method conceptual models (OOmFP), measuring the functional size of an information system in a precise and automatic way starting from its conceptual model is today a reality. The industrial application of the OO-Method modelling tools has resulted in their evolution, incorporating support for new functional elements. The present work shows the measurement rules associated to the new functional elements supported by OO-Method conceptual models, applying these rules in tools that generate executable code from OO-Method conceptual models. Finally, a comparative analysis is performed over OO-Method models of real systems. The comparative anal…
UPC++ for bioinformatics: A case study using genome-wide association studies
2014
Modern genotyping technologies are able to obtain up to a few million genetic markers (such as SNPs) of an individual within a few minutes of time. Detecting epistasis, such as SNP-SNP interactions, in Genome-Wide Association Studies is an important but time-consuming operation since statistical computations have to be performed for each pair of measured markers. Therefore, a variety of HPC architectures have been used to accelerate these studies. In this work we present a parallel approach for multi-core clusters, which is implemented with UPC++ and takes advantage of the features available in the Partitioned Global Address Space and Object Oriented Programming models. Our solution is base…
Defining Components in a MetaCASE Environment
2000
In this paper we describe how to improve method reusability in a metaCASE environment called MetaEdit+. The suggested component based approach helps unify design artefacts into components with explicit interfaces and meaningful context descriptions. We describe a method artefact from three perspectives: concept, content, and context. We create a component concept by using a hierarchical facet-based schema, and represent contextual relationship types by using definitional and reuse dependency, usage context, and implementation context links. This is the first attempt to explicitly define components into a metaCASE environment.
