The structure and development of energy consumption in European transition countries, i.e., 11 former socialistic republics including Croatia, which are now new EU members, are considered. For the last twenty years, transition countries have been in the processes of changing their social, economic and political structures with considerable influence on the energy sector. In these former sociali...

Trapezoids represent a significant category of tools among the innovative geometric implements in the lithic assemblages of European late glacial complexes, particularly those late Epigravettian industries from the Mediterranean region to the southern Ukrainian plain. The recen t recovery of several artifacts from two excavlllions in the Venetian Pre-Alps (northern Italy) prompted a large-scale...

Abstract – The paper considers end-use electricity consumption and efficiency trends in transition countries, i.e. ten former socialist states that are now new EU members, and the Republic of Croatia as a candidate country. For the last twenty years, transition countries are in the process of changing their social, economic and political structures with considerable influence on the electricity...

Within the ubicomp and related communities two areas are receiving attention, mobile phone-based reminders and techno-spiritual practices. We explore the relationship of these through the development and real world deployment of “sun dial,” a mobile Islamic call to prayer application that alerts American Muslims to daily salāt times. We describe the design, a formative evaluation, and a two-wee...

In this paper we compare and evaluate suitable methods for delivering broadband services at the metro and backbone level. In particular, the paper presents a techno-economic analysis of two key broadband technologies for metropolitan and backbone networks: The studies are based on a modelling methodology for network value analysis that involves CAPEX and OPEX calculations, while the overall tec...

Munksøgård is a housing community near the city of Roskilde, Denmark. In 2014, Munksøgård's residents have agreed to change the existing heat supply system. The choice of future heat supply was narrowed to heat pumps, new biomass boiler and connection to nearby district heating network. The present paper compares results from techno-economic energy system analysis, simple private-economic analy...
