An experimental study of a refrigerating plant when replacing R22 with HFCs refrigerants
2011
This paper presents the results of an experimental analysis comparing the performance of a vapour compression refrigerating unit operating with R22, and its performance in comparison to some HFCs fluids, substituting the former according to reg. n. 2037/2000. In particular, the plant working efficiency was first tested with R22 and then with three HFC fluids: R417A, R407C and R404A. The investigation verified that the performance with HFCs refrigerants did not result as efficient as when using R22. An environmental analysis also was performed.

Studying the User Experience in Online Banking Services: An Eye-Tracking Application
2019
Abstract Neuromarketing as research method contrbutes to understanding consumer behavior a step further than traditional marketing research. The aim of the current study is to explore the usability and cognitive understanding of banking services webpages. In this regard, the theoretical part of the article reviews the relevant literature related to neuromarketing as research method and the use of eye-tracker as research technique. Further on, a two-step research design was developed for studying the consumers’ attention and memory during and after viewing two Romanian banking services websites. The results showed that the way information is structured and presented on the webpages influence…

Macro-regional Strategies, Cohesion Policy and Regional Cooperation in the European Union: Towards a Research Agenda
2018
Since 2009, the European Union has developed strategies for the Baltic Sea, Danube, Adriatic-Ionian and Alpine macro-regions. These macro-regional strategies represent a new tool of European Union governance that seeks to combine the community’s territorial cooperation and cohesion policy repertoire with intergovernmental ‘regional cooperation’ involving European Union member and partner countries. By establishing comprehensive governance architectures for cross-sectoral and trans-boundary policy coordination in areas such as transport infrastructure and environmental protection, macro-regional strategies seek to mobilise European Union member and non-member states alike in promoting and h…
Volatility Weighting over Time in the Presence of Transaction Costs
2019
Numerous empirical studies demonstrate the superiority of dynamic strategies with a volatility-weighting-over-time mechanism. These strategies control the portfolio risk over time by adjusting the risk exposure according to updated volatility forecasts. Yet, to reap all the benefits promised by volatility weighting over time, the composition of the active portfolio must be revised rather frequently. Transaction costs represent a serious obstacle to benefiting from this dynamic risk control technique. In this article, we propose a modified volatility-weighting strategy that allows one to reduce dramatically the amount of trading costs. The empirical evidence shows that the advantages of the …
