An approach to the application of additive manufacturing for water environments: A case study to measure dissolved carbon dioxide
(Universitat Jaume IUniversitat Politècnica de Catalunya, 2023)
This paper describes the design of a case for the grouping and protection of the elements required for the quantification of dis solved carbon dioxide, allowing measurements to a depth of 10 meters. The possibility of ...
Vapour compression and caloric refrigeration in combination for a new hybrid refrigeration system
(International Institute of Refrigeration (IIR), 2023-08-21)
Although caloric refrigeration systems, such as magnetic and elastocaloric ones have shown promising
potential in the last decade, their application in stand-alone applications remains scarce. Namely, they can
provide ...
Experimental evaluation of different refrigeration system configurations using CO2-based blends as refrigerants
(International Institute of Refrigeration (IIR)Institute International du Froid (IIR), 2023-08)
Recently, blends created by mixing CO2 with another fluid with a higher critical temperature are being
considered, to allow subcritical operation at high outdoor temperature, thus increasing the COP. The goal of
this ...
Experimental evaluation of alternative CO2-based blends for transcritical refrigeration systems
(International Institute of Refrigeration (IIR), 2023-08-21)
This work presents two refrigerant CO2 blends with R32 and R1270 designed with a theoretically nonflammability and a GWP below 150. Both mixtures were tested in a small-capacity vapour compression
system with and without ...

Influence of track modelling in modal parameters of railway bridges composed by single-track adjacent decks
(Universitat Politècnica de València, 2022-05-01)
A significant number of railway bridges composed by simply-supported (SS) spans
are present in existing railway lines. Special attention must be paid to short to medium span
length structures, as they are prone to ...
Estudio de las soluciones a la problemática de los microvertederos incontrolados: aplicación al caso de Castellón
(Asociación Española de Dirección e Ingeniería de Proyectos (AEIPRO), 2016)
Although the law has forbidden uncontrolled dumping of waste in Spain since 1998 (Law
