Experimental Validation of Maximum Constant Boost Control and Switching Frequency Optimal for three-phase Quasi-Z-Source Converters
2020
This paper presents a modified modulation scheme for quasi-Z-Source converters, based on the Maximum Constant Boost Control (MCBC) concept and Switching Frequency Optimal (SFO) as reference signal. The effectiveness of the proposed technique is validated by comparing the obtained results (in terms of AC harmonic content and voltage stress) with those carried out from traditional modulation schemes. For this reason, a test bench has been assembled and the benefits of the SFO MCBC modulation scheme have been valuated.
Electrochemical sensor for phosphate ions based on laser scriber reduced graphene oxide
2022
This preliminary work shows a new and innovative way to produce laser scribed reduced graphene oxide (LSGO) electrodes using different porous substrates (ranging from paper to plastic and fabric). The obtained electrodes were also tested as electrochemical sensors towards the detection of phosphate ions in water. To obtain the electrodes, a water suspension of GO was filtered on top of substrate (such as Whatman® filter paper) and a complete sensor was obtained from its reduction using a CO2 laser. The electrode is composed of working and counter electrodes made of LSGO and a reference electrode of a Ag/AgCl obtained by using a commercial AgCl conductive paste. Phosphate ions were detected …
El Voto Económico en España
2015
En general se admite que el estado de la economía influye en los votantes y los políticos son plenamente conscientes de ello. Como dice Kiewiet se apoya al candidato que proporciona 'buenos tiempos', y se va en contra de quien gobierna en época de empeoramiento económico. Antes de otorgar el voto, los electores valoran el entorno político, social y económico del país. Qué les induce a inclinarse hacia un candidato se puede explicar a posteriori, estudiando aquello que determinó el sentido del voto en el pasado. El investigador puede observar un momento del tiempo (una o como mucho dos elecciones), o puede realizar un análisis longitudinal, con el deseo de aclarar qué influye en el votante c…
Maltrato y enfermedad mental. Estudio de personas con enfermedad mental, víctimas de maltrato
2011
Se realiza un trabajo de investigación sobre la victimización de personas con enfermedad mental, desde la perspectiva de que este colectivo es con frecuencia víctima de maltrato, a pesar de los prejuicios y el estigma que pende sobre él. Dada su especial vulnerabilidad social, los y las profesionales que atienden a esta población tienen la responsabilidad de visibilizar este fenómeno, y validar los instrumentos de diagnóstico que utilizan como útiles para detectar maltrato. The thesis involved research on the victimization of people with mental illness from the angle of this group often being the victim of abuse, despite the prejudice and stigma that hangs over it. Given its special social …
Ontology and protocol secure for SCADA
2014
In this work, we present a semantic cyber security system and we study its semantic intelligent systems vulnerabilities, focusing on the semantic attacks. For resolving semantic problems we propose a security global solution for the new generation of SCADA systems. The proposed solution aims at protecting critical semantic SCADA processes from the effects of major failures and semantic vulnerabilities in the modern IT-SCADA network. We used a security block in the global network access point, security protocols deployed in different network (OSI) levels and security ontologies deployed in security devices. We used our mixed coordinates (ECC) cryptography solution, this is an encryption tech…
Anàlisi sobre la figura/institució del Comissionat del menor: Pare d'Òrfens contemplada a la Llei 12/2008 de Protecció a la infància i l'adolescència…
2012
The concept / institution of the Commissioner for Children ' 'Pare d'Òrfens' appears for the first time in Valencia with Law 12/2008 on Protection of Children and Adolescents. The purpose of this article is to inform readers of the existence of this concept / institution, analysing the regulatory development that has taken place and comparing its performance with other similar concepts/institutions existing in other Spanish regions, in order to critically assess the work done in recent years. To close the paper, we give a number of conclusions drawn after completing the research on this concept / institution, including several general recommendations in the form of constructive criticism.
A qualitative study of pre-service teachers’ experienced benefits and concerns of using motivational interaction in practice after a training course
2022
This is a pre-print of a published study: Renko, E., Koski-Jännes, A., Absetz, P. et al. A qualitative study of pre-service teachers’ experienced benefits and concerns of using motivational interaction in practice after a training course. Humanit Soc Sci Commun 9, 458 (2022). https://doi.org/10.1057/s41599-022-01484-y Despite its positive effects on physical activity promotion, motivational style of interaction by health professionals is not easily taken up, as shown by meta-analyses of training courses. The concerns professionals experience for taking up the novel skills remain an open question. Preservice physical education teachers were offered a 16-hour training course on motivational i…
Examining Consumers’ Usage Intention of Contactless Payment Systems
2019
Purpose The purpose of this paper is to develop and test a conceptual model that combines the modified Unified Theory of Acceptance and Use of Technology (UTAUT2) with a consumer brand engagement (CBE) model to predict consumers’ usage intentions toward contactless payment systems in a developed country. Design/methodology/approach The authors cooperated with a contactless payment service provider in Finland and reached out to 22,000 customers, resulting in 1,165 usable responses. The collected data were analyzed using structural equation modeling. Findings The study shows that the UTAUT2 and the CBE model together explain approximately 70 percent of the variance in usage intention. Of the…
The Effects of Cold Water Immersion on the Recovery of Drop Jump Performance and Mechanics : A Pilot Study in Under-20 Soccer Players
2020
Cold water immersion (CWI) is a popular method used for enhancing recovery from exercise. However, the efficacy of this approach is inconclusive and studies investigating variables contributing to overall performance are scarce. Additionally, few studies have investigated the recovery of stretch-shortening cycle (SSC) performance after a fatiguing SSC task. The SSC occurs naturally in human locomotion and induces a recovery pattern different from isolated muscle contractions (e.g., pure eccentric exercise). Therefore, the main aim of this study was to investigate the effects of a single CWI on jumping performance and mechanics after exhaustive SSC exercise. On a sledge apparatus, 10 male un…
