This research investigates the potential of natural jute fibre nets to enhance the flexural strength of geopolymer concrete tiles. Two types of jute fibre grids with surface densities of 120g/mm² and 220g/mm² were tested in four configurations. The objective was to determine the configuration that most …

The Heating Ventilation and Air Conditioning (HVAC) sector is responsible for a large part of the total worldwide energy consumption, a significant part of which is caused by incorrect operation of controls and maintenance. HVAC systems are becoming increasingly complex, especially due to multi-commodity …

Even though mango productivity in Ethiopia is low due to moisture stress, there is no report on how such constraint could alleviate using Cocoon water-saving technology. Cocoon is small water reservoir technology which uses for plant growth in dry season. The objectives of this study were to introduce …

A bioaugmentation approach was used to enhance the performance of anaerobic digestion (AD) using cow manure (CM) as the substrate in a continuous system. To obtain the desirable microbial culture for bioaugmentation, a biochemical methane potential test (BMP) was used to evaluate three commonly used …

Current methods for energy diagnosis in heating, ventilation and air conditioning (HVAC) systems are not consistent with process and instrumentation diagrams (P&IDs) as used by engineers to design and operate these systems, leading to very limited application of energy performance diagnosis in practice. …

The overriding purpose of the thesis research is to develop new design concepts for improved and sustainable asphalt mixes. To accomplish this goal, it became necessary to reach some prerequisite goals. Determining what a sustainable asphalt means, and how that ideal is connected with the field of asphalt …

De toenemende marktvraag naar diepgevroren aardappelproducten, appetizers en gedroogde aardappelvlokken is aanzienlijk groter dan dat LWM momenteel met de huidige capaciteit kan produceren. Deze groei heeft er helaas toe geleid dat de focus op de efficiëntie is verzwakt, wat heeft geresulteerd in een …

The future energy system could benefit from the integration of the independent gas, heat and electricity infrastructures. In addition to an increase in exergy efficiency, such a Hybrid Energy Network (HEN) could support the increase of intermittent renewable energy sources by offering increased operational …

Reducing the use of pesticides by early visual detection of diseases in precision agriculture is important. Because of the color similarity between potato-plant diseases, narrow band hyper-spectral imaging is required. Payload constraints on unmanned aerial vehicles require reduc- tion of spectral bands. …

Within this paper, biomass supply chains, with different shares of biomass co-combustion in coal fired power plants, are analysed on energy efficiency, energy consumption, renewable energy production, and greenhouse gas (GHG) emissions and compared with the performance of a 100% coal supply chain scenario, …
