Voltage sensing buck converter-based technique for maximum photovoltaic solar energy delivery

A voltage sensing buck converter-based technique for maximum solar power delivery to a load is presented. While retaining the features and advantages of the incremental conductance algorithm, this technique is more desirable because of single sensor use. The technique operates by maximising power at the buck converter output instead of the input.

Violence and social memory in twentieth century Belfast:Stories of Buck Alec Robinson

This article explores the life and commemoration of Buck Alec Robinson. A feared loyalist killer in 1920s Belfast, in more recent times he has featured as a lion-keeping “character” on wall murals and in tourist guide books. Robinson is employed as a case study to investigate two separate but, in this case, interlinked historiographical debates. The first involves Norbert Elias’s analysis of the decline of violence. The second relates to discussion of the analysis of social memory in working class communities, with violence being placed therein. The article supports historical assessments suggesting that the “civilizing offensive” had an uneven impact. That point is usually made in the context of working class men. This article extends it to political elites in Belfast and probes their flirtations with violent hard men. The case is made that it is a mistake to assume the “civilizing” dynamic is to be understood as a teleological or top-down process.

More bang for your buck: Super-adiabatic quantum engines

The practical untenability of the quasi-static assumption makes any realistic engine intrinsically irreversible and its operating time finite, thus implying friction effects at short cycle times. An important technological goal is thus the design of maximally efficient engines working at the maximum possible power. We show that, by utilising shortcuts to adiabaticity in a quantum engine cycle, one can engineer a thermodynamic cycle working at finite power and zero friction. Our findings are illustrated using a harmonic oscillator undergoing a quantum Otto cycle.

The Harold Hutton Sports Center, completed in 1978, is named in honor of this former trustee, and made possible by a gift from his widow, Betty Hutton Williams.

La educación en las novelas de Jean Marie de Buck.

Estudiar en las obras 'Dios hablará esta noche' y 'El silencio de un adolescente' de Jean Marie de Buck. Las principales ideas pedagógicas contenidas en estas novelas se reducen a: realismo pedagógico. El educando tiene múltiples posibilidades y la educación actuando sobre ellas produce resultados positivos. Por estos motivos, hay que mantener en el adolescente un alto nivel de exigencia en los aspectos personal, social y trascendente. La educación es una obra que se tiene que llevar a cabo en común entre el educando y los distintos educadores que le ayudan. Dios habla a través de las personas, de las cosas de los acontecimientos. Hay que fomentar en el educando una disposición de apertura al mensaje que se le dirige y que únicamente él puede realizar.

Pedagogía de J. M. de Buck.

Señalar que J. M. de Buck en su vida y en su obra es un auténtico pedagogo. El autor hace una critica bastante dura de la burguesia, presenta una burguesia que teme el esfuerzo físico, que abusa de la comodidad, que no sabe adaptarse a una ley de acción y que vive refugiado en su orgullo de casta. En esto mismo algunas veces se contradice, en su novela 'Dios hablará esta noche' demuestra lo contrario, comprobamos que no todos estos chicos carecen de carácter y de dominio. Subraya la importancia de la formación de los padres. Se excede quizá al acusarlos siempre de ser la causa de los fracasos. Trata bastante superficial lo referente al adolescente en su evolución, no puntualiza bien. Pasa por alto la educación sexual, siendo uno de los problemas que presentan mayor dificultad a esta edad. La educación estética, aunque no la estudia por separado, la encontramos a lo largo de toda la novela, de manera especial en 'Dios hablará esta noche'. Aunque su obra no es un tratado cientifico su pedagogía convence porque está al alcance de todos, es sencilla y facilmente aplicable. Insiste en la importancia de una buena educación inicial, de donde se deduce la necesidad de formación en los padres. El factor determinante principal es el ambiente familiar. La familia es la que consolida y complementa la inteligencia y todo cuanto de social hay en la educación. Se nota la importancia que da a la educación social en la adolescencia. En cuanto al educador señala como indispensable el principio del ser. Para educar no basta saber, es necesario ante todo ser. Interés del método psicopedagogico y de la necesidad del médico para la educación no sólo de anormales sino también de los normales. Insiste en la educación positiva más que represiva: em la política de relación y de persuasión para dirigir al adolescente.

Dancy on buck passing

I defend the buck-passing account of value from Dancy's critique.

The buck passing account of value: assessing the negative thesis

The buck-passing account of value involves a positive and a negative claim. The positive claim is that to be good is to have reasons for a pro-attitude. The negative claim is that goodness itself is not a reason for a pro-attitude. Unlike Scanlon, Parfit rejects the negative claim. He maintains that goodness is reason-providing, but that the reason provided is not an additional reason, additional, that is, to the reason provided by the good-making property. I consider various ways in which this may be understood and reject all of them. So I conclude that buck-passers cannot reject the negative claim.

Controle Robusto Aplicado a Conversor Buck-Boost em Sistemas Fotovoltaicos

The need to implement a software architecture that promotes the development of a SCADA supervisory system for monitoring industrial processes simulated with the flexibility of adding intelligent modules and devices such as CLP, according to the specifications of the problem, it was the motivation for this work. In the present study, we developed an intelligent supervisory system on a simulation of a distillation column modeled with Unisim. Furthermore, OLE Automation was used as communication between the supervisory and simulation software, which, with the use of the database, promoted an architecture both scalable and easy to maintain. Moreover, intelligent modules have been developed for preprocessing, data characteristics extraction, and variables inference. These modules were fundamentally based on the Encog software
