A Hybrid k-Means Cuckoo Search Algorithm Applied to the Counterfort Retaining Walls Problem

García, José; Yepes, V.; Martí Albiñana, José Vicente (MDPI AG, 2020-04)

[EN] The counterfort retaining wall is one of the most frequent structures used in civil engineering. In this structure, optimization of cost and CO2 emissions are important. The first is relevant in the competitiveness ...
Analysing the potential of a simulation-based method for the assessment of CO2 savings from eco-innovative technologies in light-duty vehicles

Gil-Sayas, Susana; Komnos, Dimitrios; Lodi, Chiara; Currò, Davide; Serra, Simone; Broatch, A.; Fontaras, Georgios (Elsevier, 2022-04-15)

[EN] Mandatory targets are set in Europe for Carbon Dioxide (CO2) emissions of light-duty vehicles. EU law recognises the potential of certain innovative technologies to contribute to reducing CO2 emissions. Vehicle systems ...
Analysis of CO2 as bioindicator of termite degradation in wood structures

Oliver Villanueva, José Vicente; Ibiza-Palacios, M.S.; Lerma Arce, V.; Luzuriaga, J. E.; Lemus Zúñiga, Lenin Guillermo (Statny Drevarsky Vyskumny Ustav, 2019)

[EN] The research performed exhaustive experiments to help better understand how subterranean termite colonies function in their biodegradation activity in wooden structural elements. Specifically, the research had as main ...
Analysis of the Influence of Geometric Design Consistency on Vehicle CO2 Emissions

Llopis-Castelló, David; Camacho-Torregrosa, Francisco Javier; García García, Alfredo (Elsevier, 2019)

[EN] Highway vehicles driving on rural roads account for more than 50% of all CO2 emissions produced by the transportation sector in Europe. Although the policy measures to mitigate Greenhouse Gas emissions are increasing, ...
Analysis of two biochars and one hydrochar from different feedstock: focus set on environmental, nutritional and horticultural considerations

Fornes Sebastiá, Fernando; Belda Navarro, Rosa María; Lidón Cerezuela, Antonio Luis (Elsevier, 2015-01-01)

[EN] Two biochars, one from forest waste (BCH-FW) and the other from olive mill waste (BCH-OMW), and one hydrochar from forest waste (HYD-FW) were analyzed from the horticultural and environmental point of view. Several ...
Black Hole Algorithm for Sustainable Design of Counterfort Retaining Walls

Yepes, V.; Martí Albiñana, José Vicente; García, José (MDPI AG, 2020-04)

[EN] The optimization of the cost and CO 2 emissions in earth-retaining walls is of relevance, since these structures are often used in civil engineering. The optimization of costs is essential for the competitiveness of ...
CO2-Optimization of Post-Tensioned Concrete Slab-Bridge Decks Using Surrogate Modeling

Yepes-Bellver, Lorena; Brun-Izquierdo, Alejandro; Alcalá-González, Julián; Yepes, V. (MDPI AG, 2022-07)

[EN] This paper deals with optimizing embedded carbon dioxide (CO2) emissions using surrogate modeling, whether it is the deck of a post-tensioned cast-in-place concrete slab bridge or any other design structure. The main ...
Impact of horizontal geometric design of two-lane rural roads on vehicle CO2 emissions

Llopis-Castelló, David; Pérez Zuriaga, Ana María; Camacho-Torregrosa, Francisco Javier; García García, Alfredo (Elsevier, 2018)

[EN] In 2014, highway vehicles accounted for 72.8% of all Greenhouse Gases emissions from transportation in Europe. In the United States (US), emissions follow a similar trend. Although many initiatives try to mitigate ...
Life cycle greenhouse gas emissions of blended cement concrete including carbonation and durability

García Segura, Tatiana; Yepes Piqueras, Víctor; Alcalá González, Julián (Springer Verlag (Germany), 2014-01)

Purpose Blended cements use waste products to replace Portland cement, the main contributor to CO2 emissions in concrete manufacture. Using blended cements reduces the embodied greenhouse gas emissions; however, little ...
