District heating networks: enhancement of the efficiency
2019
International audience; During the decades the district heating's (DH) advantages (more cost-efficient heat generation and reduced air pollution) overcompensated the additional costs of transmission and distribution of the centrally produced thermal energy to consumers. Rapid increase in the efficiency of low-power heaters, development of separated low heat density areas in cities reduce the competitiveness of the large centralized DH systems in comparison with the distributed cluster-size networks and even local heating. Reduction of transmission costs, enhancement of the network efficiency by optimization of the design of the DH networks become a critical issue. The methodology for determ…
Next-generation sequencing: big data meets high performance computing
2017
The progress of next-generation sequencing has a major impact on medical and genomic research. This high-throughput technology can now produce billions of short DNA or RNA fragments in excess of a few terabytes of data in a single run. This leads to massive datasets used by a wide range of applications including personalized cancer treatment and precision medicine. In addition to the hugely increased throughput, the cost of using high-throughput technologies has been dramatically decreasing. A low sequencing cost of around US$1000 per genome has now rendered large population-scale projects feasible. However, to make effective use of the produced data, the design of big data algorithms and t…
Raising awareness of multilingualism as lived – in the context of teaching English as a foreign language
2020
Tässä artikkelissa esitellään mahdollisuuksia herätellä kielen oppijoiden kieli- ja kulttuuritietoisuutta. Esitellyt mahdollisuudet pohjautuvat 24 empiirisen tutkimuksen kriittiseen arviointiin. Tutkimuksissa käytettiin kuvataiteisiin pohjautuvia visuaalisia menetelmiä. Tällaisten menetelmien avulla on mahdollista pohtia aikaisempia kokemuksia tai kuvitella tulevaisuutta ja näin reflektoida erilaisia monikielisyyden kokemuksia. Näitä voivat olla identiteetin rakentumiseen liittyvät kysymykset, käsitykset eri kielten käytöstä tai tulevaisuuden unelmat. Arviointimme perusteella esitämme, että niitä tehtäviä, joita käytettiin tutkimuksissa, voidaan soveltaa eri tavoin erilaisille vieraan kiele…
Chances and Problems of Cultural Anthropological Perspectives in Ancient Studies. Theories – Methods – Case Studies
2020
The Distant Worlds Journal (DWJ) is an online peer-reviewed journal established especially for presenting the research of early-career scholars on the ancient world. Each edition of the DWJ centres on a specific question or topic pertinent to the diverse disciplines engaged in the study of ancient cultures. In our fourth edition, we explore cultural anthropological theories and methods in the ancient studies, both in terms of the opportunities they offer for the study of ancient cultures and the problems they pose when applied.
Big Data in metagenomics: Apache Spark vs MPI.
2020
The progress of next-generation sequencing has lead to the availability of massive data sets used by a wide range of applications in biology and medicine. This has sparked significant interest in using modern Big Data technologies to process this large amount of information in distributed memory clusters of commodity hardware. Several approaches based on solutions such as Apache Hadoop or Apache Spark, have been proposed. These solutions allow developers to focus on the problem while the need to deal with low level details, such as data distribution schemes or communication patterns among processing nodes, can be ignored. However, performance and scalability are also of high importance when…
A HOLISTIC MULTI-METHODOLOGY FOR SUSTAINABLE RENOVATION
2019
A review of the barriers for building renovation has revealed a lack of methodologies, which can promote sustainability objectives and assist various stakeholders during the design stage of building renovation/retrofitting projects. The purpose of this paper is to develop a Holistic Multi-methodology for Sustainable Renovation, which aims to deal with complexity of renovation projects. It provides a framework through which to involve the different stakeholders in the design process to improve group learning and group decision-making, and hence make the building renovation design process more robust and efficient. Therefore, the paper discusses the essence of multifaceted barriers in buildin…
The effect of culture on educational methodologies in international business programs: an application to the iMBA program
2012
As the world becomes global, there are growing needs and opportunities for intercultural exchanges in learning processes. In the context of the Spanish University Strategy for 2015, one of the most important objectives is to increase internationalisation through international postgraduate courses (Spanish Ministry of Education, 2010). Intercultural teaching capabilities are now becoming necessary for better achieving perceived service quality among international students. In the area of business studies, research on pedagogical issues is needed in order to provide recommendations and group management implications. For instance, a challenge for international business programs is dealing with…
Complete, Exact and Efficient Implementation for Computing the Adjacency Graph of an Arrangement of Quadrics
2007
The original publication is available at www.springerlink.com ; ISBN 978-3-540-75519-7 ; ISSN 0302-9743 (Print) 1611-3349 (Online); International audience; We present a complete, exact and efficient implementation to compute the adjacency graph of an arrangement of quadrics, \ie surfaces of algebraic degree~2. This is a major step towards the computation of the full 3D arrangement. We enhanced an implementation for an exact parameterization of the intersection curves of two quadrics, such that we can compute the exact parameter value for intersection points and from that the adjacency graph of the arrangement. Our implementation is {\em complete} in the sense that it can handle all kinds of…
The species-specific monitoring protocols for plant species of Community interest in Italy
2017
The results of a project for the identification of species-specific monitoring protocols for the Italian plant species protected under the Habitats Directive (Annexes II/IV/V) are presented. The project led to the development of 118 monitoring factsheets, providing an operational guidance for 107 vascular taxa, 10 bryophytes and 1 lichen taxon. Each factsheet includes information on the species (distribution, biology, ecology, conservation status, threats, etc.) and the description of field methodologies for the detection of the two main reporting parameters, i.e. population size and habitat quality. Practical information to plan field activities are also given. Protocols were designed to a…
On thermoeconomics of energy systems at variable load conditions: integrated optimization of plant design and operation
2007
Abstract Thermoeconomics has been assuming a growing role among the disciplines oriented to the analysis of energy systems, its different methodologies allowing solution of problems in the fields of cost accounting, plant design optimisation and diagnostic of malfunctions. However, the thermoeconomic methodologies as such are particularly appropriate to analyse large industrial systems at steady or quasi-steady operation, but they can be hardly applied to small to medium scale units operating in unsteady conditions to cover a variable energy demand. In this paper, the fundamentals of thermoeconomics for systems operated at variable load are discussed, examining the cost formation process an…
