Food tray sealing fault detection using hyperspectral imaging and PCANet
2020
Abstract Food trays are very common in shops and supermarkets. Fresh food packaged in trays must be correctly sealed to protect the internal atmosphere and avoid contamination or deterioration. Due to the speed of production, it is not possible to have human quality inspection. Thus, automatic fault detection is a must to reach high production volume. This work describes a deep neural network based on Principal Component Analysis Network (PCANet) for food tray sealing fault detection. The input data come from hyperspectral cameras, showing more characteristics than regular industrial cameras or the human eye as they capture the spectral properties for each pixel. The proposed classification…
The implications of diabetic foot health-related with quality of life: A retrospective case control investigation
2022
[Abstract] The diabetes people show a significant presence of foot health problems are usually all over the world, causing in big economic effects for these persons, their families and world population OBJECTIVE: The purpose of this research is to evaluate and relate the impact of foot health associated with the quality of life (QoL) in a group of people with and without diabetes MATERIAL AND METHODS: A total of 150 persons of a mean age of 71.45 ± 11.93 years came to a foot and ankle specialist outpatient center. Self-reported data were medical records where persons'with and without diabetes was evaluated. All findings obtained was compared with scores quality of life using the tool Foot H…
Sustainable bioactive pectin-based films to improve fruit safety via a circular economy approach.
2023
This work reports on the valorisation of persimmon (Diospyros kaki Thunb.) for the development of food-grade antiviral coatings against major viral foodborne pathogens, human noroviruses (NoVs) and hepatitis A virus (HAV). Initially, the antiviral activity of polyphenol-rich pectin extracts with abundant non-covalent interactions (PPN), pectin extracts enriched with intact pectin-polyphenol ester and O-glycosyl bonds (PPC) and hydro-ethanolic polyphenol-rich extracts (EPE) was compared. Higher viral reductions were found for the pectin extracts rich in polyphenols, mainly in those containing covalent pectin-polyphenol interactions. This specific extract was mixed with commercial citrus pect…
Quality recognition as a prescriber against disinformation
2022
El contexto mediático híbrido y la infodemia han incrementado el peligro de la desinformación, sobre todo entre los jóvenes, que mayoritariamente consumen contenidos digitales. Este artículo tiene como objetivo conocer las competencias y habilidades para detectar contenidos de baja calidad vinculados con la desinformación por parte de estudiantes de Periodismo y Comunicación de Argentina, Chile y España. A partir de un doble estudio comparativo, por países y nivel de formación, se pretende determinar las destrezas de futuros periodistas en el reconocimiento de información falsa. A través de un cuestionario online, los participantes (N=300) evaluaron la calidad observada (mínima, media o exc…
BPM for quality assurance systems in higher education
2014
Arran de la posada en marxa de l'Espai Europeu d'Educació Superior, les universitats espanyoles han dissenyat sistemes de garantia interna de qualitat per als seus centres i les seues titulacions. Aquest article presenta en detall el Sistema Informàtic de Garantia Interna de Qualitat de la Universitat de València (SIGIQ-UV), una eina informàtica de codi obert que integra tecnologies de gestió de processos de negoci amb tecnologies de repositori documental per al seguiment dels procediments de qualitat i l'emmagatzematge de les evidències documentals resultants de la seua execució. L'aproximació modular amb què ha estat desenvolupat garanteix la flexibilitat del sistema, l'estat d'implantaci…

Objetivo: Revisar los requisitos de calidad y usos recomendados de los diferentes tipos de mascarillas con objeto de optimizar su uso y facilitar la identificación de los productos no conformes. Método: Se hizo una búsqueda bibliográfica en PubMed, en el Boletín Oficial del Estado y Eudralex; se revisaron las páginas web de los Ministerios de Industria, Comercio y Turismo y Sanidad, así como las normas UNE. Resultados: Los diferentes tipos de mascarillas que se pueden encontrar en el mercado se acogen a diferentes exigencias regulatorias. Las mascarillas higiénicas no se consideran productos sanitarios ni equipo de protección individual y no necesitan autorización. No llevan marcado CE y de…
Antecedents and consequences of virtual customer co-creation behaviours
2019
Purpose The purpose of this paper is to compare the antecedents and consequences of two distinct types of virtual co-creation behaviours that require different degree of effort from the customer, i.e. customer participation (CPB), and customer citizenship (CCB) behaviour, in a cross-cultural study. Design/methodology/approach A survey was conducted among members of online panels in the UK and Spain, reaching a sample of 800 online individuals who participate in online co-creation processes with fashion retailers. This design allows us to test the cross-cultural effects. Multi-group structural equations modelling was used to analyse the data. Findings Virtual co-creation behaviours are driv…
Bladder cancer index: cross-cultural adaptation into Spanish and psychometric evaluation.
2014
Background: The Bladder Cancer Index (BCI) is so far the only instrument applicable across all bladder cancer patients, independent of tumor infiltration or treatment applied. We developed a Spanish version of the BCI, and assessed its acceptability and metric properties. Methods: For the adaptation into Spanish we used the forward and back-translation method, expert panels, and cognitive debriefing patient interviews. For the assessment of metric properties we used data from 197 bladder cancer patients from a multi-center prospective study. The Spanish BCI and the SF-36 Health Survey were self-administered before and 12 months after treatment. Reliability was estimated by Cronbach’s alpha.…
Axes of relationship value between manufacturers and retailers
2018
Purpose The purpose of this paper is to define the relationship strategy of manufacturers with their retail customers through the identification of axes for the creation of relationship value. Design/methodology/approach A survey was carried out and 219 valid questionnaires were completed and returned by the purchasing managers of retail companies in the furniture sector. The model was estimated using the partial least squares approach. Findings The results revealed three axes of value creation: the core axis, the information and communication technologies (ICTs) axis, and the access axis. These axes included the benefits and costs related to the product and the service provided, the ICTs …
