New Climatic Indicators for Improving Urban Sprawl: A Case Study of Tehran City
(Multidisciplinary Digital Publishing Institute, 2013)In the modern world, the fine balance and delicate relationship between human society and the environment in which we exist has been affected by the phenomena of urbanisation and urban development. Today, various environmental ... -
A Novel Method for nZEB Internal Coverings Design Based on Neural Networks
(2019)[Abstract] Research from the International Energy Agency about indoor ambiences and nearly zero energy buildings (nZEB) in the past has been centred on di erent aspects such as the prediction of indoor conditions as a ... -
Eco-friendly Pressure Drop Dehumidifier: An Experimental and Numerical Analysis
(2019)[Abstract] The northwest of Spain is defined by very high relative humidity values, with an average relative humidity of 85% throughout the year, which is considered too high by most standards and therefore can be related ... -
A Novel Method Based on Neural Networks for Designing Internal Coverings in Buildings: Energy Saving and Thermal Comfort
(2019)[Abstract] Although several papers define energy saving and thermal comfort optimization with internal coverings materials, none of them deal with predictive models to improve design in building constructions. Thus, ... -
Photovoltaic Power Prediction Using Artificial Neural Networks and Numerical Weather Data
(MDPI, 2020)[Abstract] The monitoring of power generation installations is key for modelling and predicting their future behaviour. Many renewable energy generation systems, such as photovoltaic panels and wind turbines, strongly ... -
Energy Efficiency and Thermal Performance of Office Buildings Integrated with Passive Strategies in Coastal Regions of Humid and Hot Tropical Climates in Madagascar
(MDPI AG, 2020-04-02)[Abstract] Researchers have used passive strategies, such as the implementation of thermal insulation and the use of phase change materials (PCM), in several studies, but some problems have not yet been solved. It is the ... -
A Global Review of PWR Nuclear Power Plants
(MDPI, 2020-06-27)[Abstract] Nuclear energy is presented as a real option in the face of the current problem of climate change and the need to reduce CO2 emissions. The nuclear reactor design with the greatest global impact throughout history ... -
A New Methodology for Decision-Making in Buildings Energy Optimization
(MDPI, 2020-06-30)[Abstract] When designing or retrofitting a building, not too many tools let architects and engineers to define the optimal conditions to reduce energy consumption with the minimal economic investment. This is because ... -
A New Design Criterion to Improve the Intact Stability of Galician Small Fishing Vessels
(MDPI, 2020-07-07)[Abstract] The first technical factor involved in maritime accidents is related to the lack of intact stability. The current stability criterion, based on fixing a minimum value for each of the di erent static and dynamic ... -
Spring-loaded Winch Band Brakes as Tools to Improve Safety During Mooring Operations on Ships
(2020-09)[Abstract] Some recent accident reports involving large vessels in mooring operations or breaking away from their moorings conclude that brakes of mooring winches do not render before line parts. As the potential loss of ... -
Air Changes for Healthy Indoor Ambiences under Pandemic Conditions and Its Energetic Implications: A Galician Case Study
(MDPI, 2020-10-14)[Abstract] The present paper aims to show a mathematical understanding of the e_ect of ventilation rate over building energy consumption. Moreover, as a case study to show this methodology,a proposal was analyzed of modifying ... -
New Tendencies in Wind Energy Operation and Maintenance
(MDPI, 2021)[Abstract] Both the reduction in operating and maintenance (O&M) costs and improved reliability have become top priorities in wind turbine maintenance strategies. O&M costs typically account for 20% to 25% of the total ... -
Assessment of Cold Ironing and LNG as Mitigation Tools of Short Sea Shipping Emissions in Port: A Spanish Case Study
(MDPI, 2021)[Abstract] By the end of 2025 European ports are required to provide (Directive 2014/94/EU) facilities to ensure the Liquefied Natural Gas (LNG) use and on-shore electricity supply for vessels (Cold Ironing—CI). Even though ... -
The Influence of Climate Parameters on Maintenance of Wind Farms: A Galician Case Study
(MDPI, 2021)[Abstract] There are different monitoring procedures in wind farms with two main objectives: (i) to improve energy production by the capability of the national electrical network and (ii) to reduce the stooped hours due ... -
Transition to Zero Energy and Low Carbon Emission in Residential Buildings Located in Tropical and Temperate Climates
(MDPI, 2021)[Abstract] Different methods to achieve zero-energy and low carbon on the scale of a building are shown by most of the research works. Despite this, the recommendations generally offered by researchers do not always ... -
A New Understanding and Modelling of TSP and BP Indices Compared to Safety IMO Ship Requirements
(MDPI, 2021)[Abstract] Due to the lack of information about the concept of Tons of Steering Pull (TSP) of many escort tugs, and the lack of research works relating the TSP demanded by a tethered vessel with respect to the TSP provided ... -
A Detailed Identification of Classificatory Variables in Ship Accidents: A Spanish Case Study
(MDPI, 2021)[Abstract] The present paper shows an original study of more than 163 ship accidents in Spain showing which of the usually employed variables are related to each type of vessel accident due to the lack of information in ... -
Proposal of Optimal Operation in Ship Rolling Motion Considering Sea State Conditions
(MDPI, 2022)[Abstract] Most of the research on ship rolling motion concerns a specific type of ship, such as containerships, or analyzes sailing during certain wave characteristics, rather than the full spectrum of waves that can be ... -
A New Theoretical Dynamic Analysis of Ship Rolling Motion Considering Navigational Parameters, Loading Conditions and Sea State Conditions
(MDPI, 2022)[Abstract] Despite the IMO’s efforts and the large quantity of research carried out over the years concerning the sudden loss of stability in fishing vessels, and even the damage done to merchant fleets due to cargo shifting, ... -
Research on an Internal Combustion Engine With an Injected Pre-chamber to Operate With Low Methane Number Fuels for Future Gas Flaring Reduction
(Elsevier, 2022)[Abstract] Flaring gas is the action of burning waste crude natural gas that is not possible to process or sell during the extraction and processing of oil and gas extraction. However, the surge of the oil and gas (O&G) ...
