The Near-Infrared Spectrometer and Photometer (NISP) on board the Euclid satellite provides multiband photometry R>=450 slitless grism spectroscopy in 950-2020nm wavelength range. In this reference article we illuminate background of NISP's functional calibration requirements, describe instrument's integral components, provide all its key properties. We also sketch processes needed to understand how NISP operates is calibrated, technical potentials limitations. Links articles providing more...
This paper focuses on Free Basics, a Facebook- developed mobile app that provides “free” Internet accessto many African countries. However, this humanitarian initiative came at hidden cost: lack of data protection for its users. debunks Facebook’s win-win narrative arguing the type internet connection users are connected to, and who gains from it, also matters.
Presented here is the design of Mechanical Ventilator Milano (MVM), a novel mechanical ventilator designed for rapid mass production in response to COVID-19 pandemic address urgent shortage intensive therapy ventilators many countries, and growing difficulty procuring these devices through normal supply chains across borders. This an electro-mechanical equivalent old reliable Manley Ventilator, able operate both pressure-controlled pressure-supported ventilation modes. MVM optimized...
The gLite Workload Management System (WMS) is a collection of components that provide the service responsible for distributing and managing tasks across computing storage resources available on Grid. WMS basically receives requests job execution from client, finds required appropriate resources, then dispatches follows jobs until completion, handling failure whenever possible. Other than single batch-like jobs, compound types handled by are Directed Acyclic Graphs (a set where...
Economic performativity is the idea that theories, metrics, and models developed by economic professionals, then used policymakers, affect reality they aim to describe. This can create a self-fulfilling prophecy brings world more in line with their models. paper develops theoretical framework assess how ideas are developed, turned into policy, eventually gain possibility be performative. We argue this based on three steps: firstly, economists need quantify economy, implementing process we...
Studying atmospheric neutrino oscillations in the few-GeV range with a multi-megaton detector promises to determine mass hierarchy. This is main science goal pursued by future KM3NeT/ORCA water Cherenkov Mediterranean Sea. In this paper, processes that limit obtainable resolution both energy and direction charged-current events ORCA are investigated. These include composition of hadronic fragmentation products, subsequent particle propagation photon-sampling fraction detector. GEANT...
Resource management and scheduling of distributed, data-driven applications in a Grid environment are challenging problems. Although significant results were achieved the past few years, development proper deployment generic, reliable, standard components present issues that still need to be completely solved. Interested domains include workload management, resource discovery, matchmaking and brokering, accounting, authorization policies, access, reliability dependability. The evolution...
The Euclid mission objective is to understand why the expansion of Universe accelerating through by mapping geometry dark investigating distance-redshift relationship and tracing evolution cosmic structures. project part ESA's Cosmic Vision program with its launch planned for 2020 (ref [1]). NISP (Near Infrared Spectrometer Photometer) one two instruments operating in near-IR spectral region (900- 2000nm) as a photometer spectrometer. instrument composed of: - cold (135K) optomechanical...
Since 2017, the Worldwide LHC Computing Grid (WLCG) has been working towards enabling token-based authentication and authorization throughout its entire middleware stack. Following initial publication of WLCG Token Schema v1.0 in 2019, OAuth2.0 token workflows have integrated across grid middleware. There are many complex challenges to be addressed before can end-to-end token-based, including not just technical hurdles but also interoperability with wider landscape. This paper presents...
In the first phase of European DataGrid project, 'workload management' package (WP1) implemented a working prototype, providing users with an environment allowing to define and submit jobs Grid, able find use ``best'' resources for these jobs. Application have now been experiencing about year this release workload management system. The experiences acquired, feedback received by user need plug new components implementing functionalities, triggered update existing architecture. A description...
The KM3NeT research infrastructure, currently under construction in the Mediterranean Sea, will host neutrino telescopes for identification of sources Universe and studies mass hierarchy. These house hundreds thousands photomultiplier tubes that have to be operated a stable reliable fashion. In this context, stability dark counts has been investigated with negative high voltage on photocathode held insulating support structures made 3D printed nylon material. Small gaps between rigid...
We report on our investigations into the viability of ARM processor and Intel Xeon Phi co-processor for scientific computing. describe experience porting software to these processors running benchmarks using real physics applications explore potential production processing.
Geant4 is a simulation system of particle transport through matter, widely used in several experimental areas from high energy physics and nuclear experiments to medical studies. Some its applications may involve critical use cases; therefore they would benefit an objective assessment the software quality Geant4. In this paper, we provide first statistical evaluation metrics data related set packages. The analysis aims at identifying risks for maintainability, which being addressed early...
Within the context of Competence Centre for Conservation Cultural Heritage (4CH) project, design and deployment a platform-as-a-service cloud infrastructure first European competence centre cultural heritage (CH) has begun, some web services have been integrated into platform. The service is INFN-CHNet application FAIR storage scientific analysis on CH: THESPIAN-Mask. It based CIDOC-CRM-compatible ontology CRMhs, describing metadata. To ease process metadata generation data injection,...
Several years of research are establishing Petri nets as a modeling formalism for scientific workflows; their formal semantics and the existence several analysis tools, among others, make them suitable complex concurrent processes' description. However, non-determinism Net model clashes with imperative Turing- based environment provided by mainstream programming languages such C/C++, Java C#. Therefore design decisions must be taken in order to provide concrete implementation Net-based...
