This paper investigate to use of information technology, i.e. machine learning algorithms for water assessment in Timor-Leste. It is essential to access clean water to ensure the safety for humans and others livings in this world. The Water Quality Index (WQI) is the standard tool for assessing water …

Climate change calls for an energy transition utilizing all available renewable energy resources, such as bioenergy from biomass. However, the use of biomass is debated in society, and public acceptance is low or lacking. This survey-based research demonstrates for the first time that public acceptance …

Positive Energy Districts (PEDs) are a promising approach to urban energy transformation, aiming to optimize local energy systems and deliver environmental, social and economic benefits. However, their effectiveness and justification for investment rely on understanding the additional value they provide …

The energy community movement has grown considerably over the past ten years. Energy communities are also expanding their activities. However, room for new energy projects is limited because of grid congestion. Therefore, citizen energy communities (CECs) are looking for ways to reduce the pressure on …

Concrete is arguably the most widely used building material in the world today. Current estimates of world cement manufacture are of the order of 1.7*109 tons per year, enough to produce well over 6 km3 of concrete per year or at least 1 m3 per person (Gartner, 2004). It is a composite material made …
