The Compressive Strength and Microstructure of Alkali-Activated Binary Cements Developed by Combining Ceramic Sanitaryware with Fly Ash or Blast Furnace Slag
MDPI (2018)The properties of a binder developed by the alkali-activation of a single waste material can improve when it is blended with different industrial by-products. This research aimed to investigate the influence of blast ... -
The connection between the heat storage capability of PCM as a material property and their performance in real scale applications
Elsevier (2017-06)Using phase change materials (PCM) for Thermal Energy Storage, the most important material property is their heat storage capability, usually given as h(T). Ideally, h(T) changes suddenly at a single temperature. However, ... -
The contact angle of nanofluids as thermophysical property
Elsevier (2019-07-01)Droplet volume and temperature affect contact angle significantly. Phase change heat transfer processes of nanofluids – suspensions containing nanometre-sized particles – can only be modelled properly by understanding these ... -
The Cost of Change in Parametric Modeling: A Roadmap
CAD Solutions (2021)In this paper, we lay the foundation for estimating the cost associated to parametric modeling changes and discuss its implications on the broader context of engineering change management. We provide an analysis of the ... -
The determination of waste generation and composition as an essential tool to improve the waste management plan of a university
Elsevier (2016-07)When many people work in organized institutions or enterprises, those institutions or enterprises become big meeting places that also have energy, water and resources necessities. One of these necessities is the correct ... -
The effect of information and communication technologies on creativity in collaborative design
Springer Verlag (2016)This study compares the degree of creativity of forty-two conceptual designs proposed as solutions to two innovative design problems developed in face-to-face and virtual collaborative environments. The solutions obtained ... -
The effect of nature on designers' creativity, according to their personality profile
Elsevier (2020-04)The aim of this work is to demonstrate whether natural environments, either real or simulated, tend to enhance designers' creativity, and whether the effects differ depending on their personality profile. Numerous studies ... -
The Heritagization of a Mediterranean Vernacular Mountain Landscape: Concepts, Problems and Processes
Taylor & Francis (2018-10-04)The concepts of heritage and landscape have always changed or been developed based on the social context of the time. For decades, attempts have been made to find a pragmatic definition for a changing setting where values, ... -
The influence of design methodology on a designer’s emotional parameters and on design results
Universidad Nacional de Colombia (2016)This paper presents the results of an experiment carried out on 21 subjects, all of whom had an engineering background, with the aim of determining the influence of the designer’s attitude on the design process and on the ... -
The Mathematics of the Contagion: Applications of the SIR Model in the Study of Pandemics
Universidad Ana G. Méndez (2020-02-28)At a first glance, the epidemics phenomenon seems to be enormously complex, especially if we consider the number of factors that can influence its appearance and evolution. However, within the scope of complex systems, ... -
The relationship between personal intrinsic factors towards a design problem and the degree of novelty and circularity
Springer (2021-08-30)The aim of this work is to determine how personal intrinsic factors towards a design problem are related to novelty and circularity. A deeper understanding of this relationship will be a valuable aid when it comes to making ... -
The thermal performances of a refrigerator incorporating a phase change material
Elsevier (2019-02-06)In this paper, a Phase Change Material (PCM) has been incorporated within the cabinet of a refrigerator, attached to the bare tube evaporator placed below the racks, with the aim of analysing the variation of temperatures ... -
Theoretical comparison of low GWP alternatives for different refrigeration configurations taking R404A as baseline
