Fuel cell analytical modeling: Solving the trade-off between accuracy and complexity
2013
In this paper, a 5.5 kW Proton Exchange Membrane fuel cell is modeled. The proposed analytical model is described and the parameters identification procedure is further discussed. Simulation results of all three sub-models are compared to test the accuracy of each one. A comparison between simulation and experimental results is provided as well validating the modeling approach.
Statistical Modelling and Risk Analysis of Bitcoins Exchange Rate
2018
Master's thesis Business Administration BE501 - University of Agder 2018 Bitcoin is a phenomenon that is new and there is little information on how and why it behaves as volatile as it does. This thesis uses existing data on Bitcoin’s exchange rate to estimate a model that describes the pattern and use it in a financial risk analysis. We also aim to contribute as a foundation for further studies in this field. The statistical properties of the log-return of the exchange rate are analysed and it is deemed to be iid. From the eleven distributional candidates we study is the fitted skew generalised t distribution proven to represent the data best after evaluation by criteria and statistics. Th…
Interactions, spillovers de connaissance et croissance des économies modernes. Faut-il préférer la globalisation ou la proximité géographique ?
2009
Globalisation and metropolisation in modern economies induce some locational strategies of knowledge based activities towards cities and deeply increase trade and move of ideas across cities. In that context, we study the way knowledge spillovers have influenced the economic growth of 82 European Metropolises over the 1990-2005 period. We model knowledge spillovers across cities according to three specific interaction patterns depending either on geography or on global advanced services or thought a combination of these patterns. We show that the mixed pattern matters the best for economic growth of cities in Europe.
O funkcji substytucji frazemów w reklamie prasowej
2022
Substytucja jest metodą modyfikacji formalnej frazemu, która ze względu na swoje walory komunikacyjne i ekspresywny charakter jest jednym z ulubionych środków językowych w reklamach prasowych. Jej popularność można wyjaśnić m.in. niewyczerpanymi możliwościami wyrazistych gier językowych o różnych stopniach trudności w odbiorze. Celem artykułu jest nie tylko prezentacja substytucji jako metody formalnej modyfikacji frazemu wywołującej efekty semantyczne, ale przede wszystkim omówienie jej funkcji w reklamie prasowej. Substytucja dzięki swojej kreatywności skupia uwagę odbiorcy, zachęca do lektury oraz wzmacnia koherencję tekstu ogłoszenia prasowego. Dzięki znajomości utartego sformułowania u…
Regional currencies and regional monetary zones in Latin America : what prospects ?
2009
9 p.; This paper aims at drawing lessons from Keynes's plan presented at the Bretton Woods conference, in order to help improving current regional monetary agreements in Latin America. Some promoters of the Bank of the South and the New Financial Architecture in Latin America are proposing to implement a regional clearing system designed to allow a multilateral offsetting of the liabilities and assets generated in the reciprocal transactions of member countries in words that the British economist certainly would not have denied. This system would be very different from current regional payments aggreements that maintain an implicit reference to the US dollar as reserve or payment currency.
Regional currencies and regional monetary zones in Latin America : whats prospects ?
2010
International audience; Reducing transaction costs and the need for international reserves is a primary objective to the establishment of regional payment agreements. Another objective, especially in the case of Latin America where the Ecuadorian promoters of the Bank of the South (Banco del Sur) and the New Regional Financial Architecture are planning the implementation of a regional clearing system, is to reduce member countries' dependence on the U.S. dollar as an international standard and reserve currency. To help improve the design of such agreements, this paper refers to the plan Keynes designed for the Bretton Woods conference. First, it observes that cases were made against this pl…
The Euro and Monetary Policy Transparency
2002
This paper focuses on a possible explanation for the weakness of the euro, namely the lack of transparency of the European Central Bank's (ECB) monetary policy. In order to obtain a time-varying measure of monetary policy uncertainty in both the U.S. and Euroland, we estimate a Stochastic Volatility model using policy-adjusted short-term interest rates. We also analyze directly the impact of higher uncertainty on the euro-dollar exchange rate. The empirical findings are in line with those of other studies, and show that the U.S. Fed is more transparent than the ECB. This results in higher volatility of European interest rates, capital outflows, and a weaker euro vis-a-vis the U.S. dollar.
The role and presence of conflicts in romantic Erasmus relationships
2017
The present study assesses the presence and importance of conflicts in intercultural relationships that were created during an Erasmus exchange period abroad. The theoretical background is based upon the concepts of third culture building (TCB) and conflict management styles, both of which were used to explain the various stages of the relationship development. So far the scholarly literature on the subject of Erasmus students is rather scarce and only a few studies focus on intercultural couples’ lived experiences concerning conflicts. This study is driven by the need for more developed and valid information of Erasmus couples that in fact form a rather large number of the Erasmus students…
Overcoming Essentialism? Students’ Reflections on Learning Intercultural Communication Online
2022
The fields of intercultural communication (IC) and intercultural education are in flux and the paradigmatic shift is away from essentialist approaches on culture and interculturality towards seeing IC and interculturality as flexible, fluid, contradictory, political, and ideological constructs. This study presents a virtual exchange project, a joint introductory course on IC between a Finnish university and a French university. One of the objectives of the course was to provide students with a more critical, non-essentialist perspective on interculturality. This study presents an analysis of 32 students’ texts (learning logs) that are processed qualitatively using content analysis to find a…
Virtual Exchange: Future-ready teaching of multiliteracies across borders and cultures
2020
Virtual exchange is an online form of internationalization at home. Students from different countries collaborate in small, international groups on tasks joined by a common theme. They combine their expertise when solving problems together. The teachers act as mentors, providing facilitation and support for the students during the virtual exchange. The student teams work independently by selecting the tools for the collaboration, allocating the tasks and creating the group’s final product. Virtual exchange is a transnational learning opportunity which enables students to learn and practice how to efficiently combine and make use of their digital, visual, critical, linguistic and intercultur…
