Autonomic Brokerage Service for an End-to-End Cloud Networking Service Level Agreement
2014
8 pages; International audience; Today, cloud networking which is the ability to connect the user with his cloud services and to interconnect these services within an inter-cloud approach, is one of the recent research areas in the cloud computing research communities. The main drawback of cloud networking consists in the lack of Quality of Service (QoS) assurance and management in conformance with a corresponding Service Level Agreement (SLA). In this paper, we propose a framework for self-establishing an end-to-end service level agreement between a Cloud Service User (CSU) and multiple Cloud Service Providers (CSPs) in a cloud networking environment using brokerage service. We focus on Qo…
SMART: Unique splitting-while-merging framework for gene clustering
2014

Successful clustering algorithms are highly dependent on parameter settings. The clustering performance degrades significantly unless parameters are properly set, and yet, it is difficult to set these parameters a priori. To address this issue, in this paper, we propose a unique splitting-while-merging clustering framework, named "splitting merging awareness tactics" (SMART), which does not require any a priori knowledge of either the number …
Developing a conceptual framework for the co-operative and mutual enterprise business model
2018
AbstractThe co-operative and mutual enterprise business model represents a unique type of organisation that has a dual purpose focused on both economic and social goals. For nearly two centuries it has played an important role in economic development, job creation and addressing market failures. However, despite its potential importance to economic development it has been largely ignored within the mainstream economics and management literature. This paper provides an overview of the nature of the co-operative and mutual enterprise business model and also proposes a business model framework or ‘canvas’ that can be used for research, teaching and strategic analysis.
ASSESSMENT OF BEACH LITTER ALONG THE COAST: CASE STUDY OF THE CITY OF CADIZ (SPAIN)
2016
The United Nations Environment Program defines as waste all the persistent marine debris deposited or abandoned in the sea (marine litter) and beach (beach litter) environment. Thus including all substances or products abandoned or involuntarily dispersed into the sea or on the coastline. It has been estimated that, all around the world, about 10 million tons of waste coming from domestic, commercial and industrial activities reach the seas every year. Moreover, waste floating adrift in the seas and oceans can be carried very far away, reaching different places from the ones they were originated. Further, damage may result to various human activities and equipment, such as navigation, energ…
A STUDY OF THE πN SCATTERING DATA WITH JP = 3/2- AND A PROOF OF THE EXISTENCE OF THE N*(1700)
2014
Using an interaction extracted from the local hidden gauge Lagrangians and the coupled channels ρN (s-wave), πN (d-wave), πΔ (s-wave) and πΔ (d-wave), we look in the region of [Formula: see text] and we find two resonances dynamically generated which are naturally associated to the N*(1520)(3/2-) and N*(1700)(3/2-). The N*(1700)(3/2-) appears neatly as a pole in the complex plane. The free parameters of the theory are chosen to fit the πN (d-wave) data. The unitary coupled channel approach followed here, in connection with the experimental data, leads automatically to a pole in the 1700 MeV region and makes this second 3/2- resonance unavoidable.
Asymptotics for thenth-degree Laguerre polynomial evaluated atn
1992
We investigate the asymptotic behaviour of ? n (n),n?? where ? n (x) denotes the Laguerre polynomial of degreen. Our results give a partial answer to the conjecture ?? n (n)>1 forn>6, made in 1984 by van Iseghem. We also show the connection between this conjecture and the continued fraction approximants of $$6\sqrt {{3 \mathord{\left/ {\vphantom {3 \pi }} \right. \kern-\nulldelimiterspace} \pi }} $$ .
Integer Complexity: Experimental and Analytical Results II
2015
We consider representing natural numbers by expressions using only 1’s, addition, multiplication and parentheses. Let \( \left\| n \right\| \) denote the minimum number of 1’s in the expressions representing \(n\). The logarithmic complexity \( \left\| n \right\| _{\log } \) is defined to be \({ \left\| n \right\| }/{\log _3 n}\). The values of \( \left\| n \right\| _{\log } \) are located in the segment \([3, 4.755]\), but almost nothing is known with certainty about the structure of this “spectrum” (are the values dense somewhere in the segment?, etc.). We establish a connection between this problem and another difficult problem: the seemingly “almost random” behaviour of digits in the ba…
Assessing interactional skills in a paired speaking test : raters’ interpretation of the construct
2019
The operationalization of interactional competence (IC) within the paired speaking test format allows for a range of interactional skills to be tested. However, in terms of assessment, challenges are posed with regard to the co-constructed nature of IC, making investigations into raters’ perceptions of the construct essential to inform test score interpretation. This qualitative study explores features of IC that raters attended to as they evaluated performances in a paired speaking test, part of a Swedish national test of English as a Foreign Language (EFL). Two groups of raters, 17 EFL teachers from Sweden, using national standards based on the Common European Framework of Reference for L…
The National Bilingual Programme in Colombia: Imposition or Opportunity?
2011
The National Bilingual Programme, created by the Colombian Ministry of Education in 2004, offers all students in the county the possibility of becoming bilingual in English and Spanish as part of a vision of increased productivity in a globalised world. However, the language and education policies promoted within this framework tend to foreground the development of English at the expense of bilingual competence in Spanish and English. This bilingual policy has been strongly criticised by several Colombian academics with regard to what they consider as the imposition in the Colombian context of the Common European Framework of Reference for Languages, the disregard of local knowledge and exp…
Use your languages! : From monolingual to multilingual interaction in a language class
2015
This reflective paper presents a new course concept for multilingual interaction, which was piloted at the University of Jyväskylä Language Centre in the spring of 2014. The course, implemented as part of the centre’s action research, is the result of a development process aimed at enhancing students’ multilingual and multicultural academic communication competences along with promoting use of their entire linguistic repertoire. The course concept was inspired by the EU project Modularising Multilingual and Multicultural Academic Communication Competence (MAGICC), whose main intent is “to integrate multilingual and multicultural academic communication competences as graduate learning outcom…
