Numerical integration of subtraction terms
2016
Numerical approaches to higher-order calculations often employ subtraction terms, both for the real emission and the virtual corrections. These subtraction terms have to be added back. In this paper we show that at NLO the real subtraction terms, the virtual subtraction terms, the integral representations of the field renormalisation constants and -- in the case of initial-state partons -- the integral representation for the collinear counterterm can be grouped together to give finite integrals, which can be evaluated numerically. This is useful for an extension towards NNLO.
On the Rigorous Calculation of All Ohmic Losses in Rectangular Waveguide Multi-Port Junctions
2005
In this paper, all ohmic losses effects present in rectangular waveguide multi-port junctions are rigorous and efficiently computed. For this purpose, a new formulation based on the theory of cavities, which provides generalized admittance matrix representations for such junctions, is proposed. To validate this theory, we have successfully compared our results with numerical data of a lossy E-plane T-junction and of a hollow waveguide, as well as with experimental measurements of a real H-plane T-junction.
Temporal evolution of neoclassical tearing modes in the frequently interrupted regime
2010
A phenomenological method for description of temporal evolution of neoclassical tearing modes in the frequently interrupted regime (FIR) is proposed. The method makes it possible to predict the beginning and the end of the FIR regime as well as the frequency of the FIR drops. A few experimental parameters which are used in the model are commonly measured quantities. Several specific ASDEX Upgrade (http://en.wikipedia.org/wiki/ASDEX_Upgrade) FIR discharges with different heating and different FIR behavior are analyzed in detail.
International student mobility in Southern-Latin Europe: beyond the EU logics, towards a new space
2018
This paper discusses international student mobility (ISM) in Southern-Latin Europe, specifically Italy, Portugal, and Spain, analysing the inflow of international students as reflected in the UNESCO, OECD and European Commission databases. Only recently Italy, Portugal and Spain, as latecomers, have become more actively involved in ISM dynamics. This trend has been a response to EU pressures to internationalization, instrumented through the consolidation of the Bologna process and the need to build a common space of higher education. The analysis shows that at the intra-European level Italy, Portugal and Spain share similar ISM patterns; however, in the global context other logics shape ISM…

Comparative Analysis of Natural Gas Pipeline Interconnections
2021
The paper shows a comparison between two intervention methods for interconnecting two gas transmission pipelines within a natural gas transmission system. One intervention implies shutdown of pipelines, while the other one in-service pipelines. Each method is described in detail along with the main technological issues, as well as the related advantages and disadvantages. The technological procedures imply special working techniques such as welding or hot tapping in service pipelines.
Unpacking Higher Educational Institutions (HEIs) performances through the institutional logics lens
2019
In the current knowledge-based economy, Higher Education Institutions (HEIs) are called to play different interconnected roles related to triple university missions. Alongside the two traditional missions of teaching and research, HEIs have experienced the emergence of the so-called “third mission”, which sees HEIs as knowledge-based agents part of ecosystems of public institutions, companies and citizens oriented to coknowledge creation. Finding a balance between the traditional missions and the third mission can be a serious challenge. For this reason, HEIs need to revise their objectives, strategies and performance indicator systems to plan, monitor and assess their social, cultural, and…
Navigating multiple logics: Legitimacy and the quest for societal impact in science
2022
Academic scientists are encouraged to pursue research that delivers both scientific and societal impact. This may involve a search for alternative mechanisms of social approval which lead to endorsement of scientists’ research goals. We explore how scientists mobilise and accumulate different forms of legitimacy, which might favour their participation in practices related to innovation and societal impact. We propose three specific sources of scientific legitimacy: i) scientists’ social networks (research-related legitimacy ties), ii) prominence in the relevant academic community (reputation-based legitimacy); and direct contact with the primary beneficiaries of the research (beneficiary-ba…
Opportunities and challenges of digitized discretionary practices: a public service worker perspective
2018
Abstract Public service workers exercise discretionary power during policy implementation. Due to an immense diffusion of information and communications technology (ICT) in public service provision, they are increasingly exposed to reforms aiming at more efficient and fair decision-making. Whereas extant literature has found that ICT can both enable and constrain public service workers' ability to exercise discretion, we know less about underlying explanations for these inconclusive findings. This paper addresses this research gap by exploring how and why public service workers react to digitized discretionary practices. We draw upon institutional logics to show the underlying consideration…
Implementation of JPEG2000 arithmetic decoder using dynamic reconfiguration of FPGA
2005
This paper describes implementation of a part of JPEG2000 algorithm (MQ-Decoder and arithmetic decoder) on a FPGA board using dynamic reconfiguration. Comparison between static and dynamic reconfiguration is presented and new analysis criteria (time performance, logic cost, spatio-temporal efficiency) are defined. MQ-decoder and arithmetic decoder can be classified in the most attractive case for dynamic reconfiguration implementation: applications without parallelism by functions. This implementation is done on an architecture designed to study dynamic reconfiguration of FPGAs: the ARDOISE architecture. The implementation obtained, based on four partial configurations of arithmetic decoder…
