ArcGIS and ADMS, for control of Electrical Distribution Systems - Bok av Héctor Lara García - Häftad

ArcGIS and ADMS, for control of Electrical Distribution Systems - Bok av Héctor Lara García - Häftad

The electricity distribution system with increasing energy demand needs to incorporate an automatic control and visualisation system, tools for decision making and problem solving, such as electrical faults in the network. This is achieved with the Arcgis platform that helps in asset statistics and in the planning or dimensioning of new feeders of the electrical network and as a base or support for automatic and monitoring systems such as the ADMS system, for which the present work studies its integration..

The first graduating class of the Juvenal Miller Normal School - Bok av Josiane Alves Da Silveira - Häftad

The first graduating class of the Juvenal Miller Normal School - Bok av Josiane Alves Da Silveira - Häftad

This book aims to analyse the formation of the first class of normalistas at the \Juvenal Miller\ Normal School, as well as the work of these teachers from the 1950s onwards. To this end, six interviews were conducted, based on the theoretical-methodological framework of oral history and memory. The interviewees included five normalistas and one teacher from the first class of the public Normal Course in Rio Grande/RS. In addition, it presents the background to the creation of the Normal Course,..

State and Class Struggles in Late Capitalism: - Bok av José Cleyton Neves Lopes - Häftad

State and Class Struggles in Late Capitalism: - Bok av José Cleyton Neves Lopes - Häftad

What does Marxism say about the relationship between the bourgeois state and the class struggle? This is the question that guides this work. It is on this basis that the reflections of those who founded the so-called Marxist tradition, Karl Marx and Friedrich Engels, are retrieved. The theoretical-practical extensions promoted by Vladimir Lenin, Antonio Gramsci and Nicos Poulantzas are also emphasised. An examination of the works of these theorists reveals a complex and radically critical response..

FACIAL NERVE STIMULATOR - Bok av Habib Elkhorchani - Häftad

FACIAL NERVE STIMULATOR - Bok av Habib Elkhorchani - Häftad

The facial nerve can be stimulated with a biphasic current to unblock certain facial deformities and possibly limit facial pain. The electrical stimulator is a clinical tool that allows, on the one hand, to excite the mastoid foramen, which is a nervous zone located at the level of the lower jaw, and on the other hand, to record the muscular electrical response. This stimulator allows, with the help of electrodes, to generate variable electrical waves. The electrodes are controlled by a current programmable..

Pedagogical leadership of a class group in a school context - Bok av Youssef Hamdani - Häftad

Pedagogical leadership of a class group in a school context - Bok av Youssef Hamdani - Häftad

The idea for this essay on pedagogical animation in school education did not originate today. In fact, it has been in the back of our minds for the last ten years or so, and has gradually emerged in our investigations into measurement, evaluation and quality in education and training. The structuring aim of this work is to analyze the impact of the pedagogical animation of the class-group on the educational act in terms of teaching-learning practices in the qualifying secondary education cycle. To..

Formation of the cultural identity from the physical education class - Bok av Irma Amarilis Ponce Menéndez - Häftad

Formation of the cultural identity from the physical education class - Bok av Irma Amarilis Ponce Menéndez - Häftad

Several authors agree that cultural identity encompasses cultural traits, customs, traditions, values and beliefs of a human collective, enriched every day by the events of the past, whether remote or recent. Therefore, educational institutions should increase the mechanisms for its rescue, enrichment, preservation and transmission. Particularly from the Physical Education class the conditions for this are given, the traditional games are part of its curriculum, a propitious moment so that with all..

Water salinity and salicylic acid in guava cultivation - Bok av Cassiano Nogueira de Lacerda - Häftad

The objective of this work was to evaluate the growth, physiology, production and postharvest quality of guava cv. Paluma under salt stress and foliar application of salicylic acid. The experiment was conducted under greenhouse conditions, in a 2 × 4 factorial design, with two levels of electrical conductivity of irrigation water (0.6 and 3.2 dS m-1) and four concentrations of salicylic acid (0; 1.2; 2.4 and 3.6 mM), with three repetitions. Irrigation with 3.2 dS m-1 water promoted reductions in..

Results of experimental studies of electrical contact - Bok av Jan Solonar - Häftad

Compared to other types of electric machines, unipolar generators have a number of advantages. Simplicity of design, high overload capacity, high efficiency, absence of ripples in the current and voltage curve, possibility of direct connection to the turbine, etc. The use of superconducting winding in unipolar generators makes it possible to significantly increase the magnetic field and the generator's E.D.S.. As research has shown, it is necessary to use electric arc moving contact in unipolar ones...
