A novel method to measure the energy efficiency and performance of an auto-cascade refrigeration cycle
Elsevier (2023-10)Auto-cascade refrigeration systems are the most used cycles to maintain spaces at ultra-low temperature conditions (-80 to −60 °C). The interest in these systems has risen due to the need to maintain and distribute COVID-19 ... -
A Novel Real-Time MATLAB/Simulink/LEGO EV3 Platform for Academic Use in Robotics and Computer Science
MDPI (2021)Over the last years, mobile robot platforms are having a key role in education worldwide. Among others, LEGO Robots and MATLAB/Simulink are being used mainly in universities to improve the teaching experience. Most LEGO ... -
A Path Planning Algorithm for a Dynamic Environment Based on Proper Generalized Decomposition
MDPI (2020-12-19)A necessity in the design of a path planning algorithm is to account for the environment. If the movement of the mobile robot is through a dynamic environment, the algorithm needs to include the main constraint: real-time ... -
A Pilot Project Using Sensors in the Municipal Solid Waste Collection of a Medium-Sized City
MDPI (2023)Municipal solid waste collection must reach the recycling rates required by new regulations, like with the introduction of new bins to collect the organic fraction. The filling pattern of those bins is unknown, and the ... -
A practical approach for teaching the organic rankine cycles (ORCs) in an advanced thermodynamics course
DYNA (2020-03)Higher Education Institutions must consider the most recently developed technologies to increase energy efficiency. A significant share of the heat used in industry is wasted while still being at usable temperature levels ... -
A Practical Vision of Heritage Tourism in Low-Population- Density Areas. The Spanish Mediterranean as a Case Study
MDPI (2021-05-04)Heritage tourism bases its definition on searching for different, authentic, and somewhat unexplored places. Recent literature speaks of the growth of new forms of tourism based on the tradition that seeks to surprise ... -
A quantitative analysis of parametric CAD model complexity and its relationship to perceived modeling complexity
Elsevier (2023)Digital product data quality and reusability has been proven a critical aspect of the Model-Based Enterprise to enable the efficient design and redesign of products. The extent to which a history-based parametric CAD ... -
A review of refrigerant R1234ze(E) recent investigations
Elsevier (2016-02-25)Climate change is demonstrated through global surface temperatures increase in the last century. To stop this phenomenon, new regulations that ban or tax greenhouse gas fluids (HFC among them) have been approved. In the ... -
A Roof Refurbishment Strategy to Improve the Sustainability of Building Stock: A Case Study
MDPI (2024)The aging of the building stock in most cities highlights the relevance of refurbishment to achieve sustainability. Current refurbishment practices are often short-sighted and do not encompass holistic strategies beyond ... -
A simple procedure for generating locally refined 2D quadrilateral finite element meshes of gears
Elsevier (2020)This article describes a new procedure for automated generation of two-dimensional locally refined quadrilateral meshes of gear drives. In this new procedure, a base mesh is generated using a multiblock meshing procedure. ... -
A simplified model for shell-and-tubes heat exchangers: Practical application
Elsevier (2010)In this paper, a simplified model for the study of shell-and-tubes heat exchangers (HXs) is proposed. The model aims to agree with the HXs when they are working as condensers or evaporators. Despite its simplicity, the ... -
A simplified model to assess vulnerable areas for urban regeneration
Elsevier (2019)The plethora of approaches to assess urban sustainability entails the challenge of selecting the most appropriate model. Theoretical models constitute a necessary and valuable starting point, but here we highlight the ... -
A Study of the Flexural Behavior of Fiber-Reinforced Concretes Exposed to Moderate Temperatures
Multidisciplinary Digital Publishing Institute (2021-06-24)The use of synthetic fibers in fiber-reinforced concretes (FRCs) is often avoided due to the mistrust of lower performance at changing temperatures. This work examines the effect of moderate temperatures on the flexural ... -
A survey on 3D cad model quality assurance and testing tools
Elsevier (2017-02)A new taxonomy of issues related to CAD model quality is presented, which distinguishes between explicit and procedural models. For each type of model, morphologic, syntactic, and semantic errors are characterized. The ... -
