CONTRIBUTIONS TO APPLIED RESEARCH OF THE START SYSTEM FROM DACIA LOGAN IN ORDER TO OUTLINE
THE SIMPTOMATIC ASPECTS
The present study outlines the problems which may appear with the starter system in the case of vehicles in exploitation. After many starting procedures the starter motor wear out and doesn’t work properly, making the vehicle use and pre-operation sequences more and more difficult. The worst case scenario is when starter stops suddenly in the middle of a junction without symptoms and as an aggravating aspect with impossibility to restart immediately. Analyzing the starting system and complex assembly of components allows the engineers to obtain some significant knowledge in the intricate character of optimal functionality in order to develop proper know-how and skills in repairing the system or solving the problem once it has appeared. The development of present work has the purpose to define the starting system and the methods for saving energy and time in the process of application or switching the engine’s turn on procedures. The paper experimental part points out some of the significant symptoms and problems related to the electric starter motor and internal combustion engine starting system on Dacia Logan sedan.

THE ACTIVATOR VALANCES OF INTEGRATED
APPROACH TO THE PRIMARY SCHOOL
“The master argument for curricular integration is simply that life is not divided into subjects”. (James Moffett). One of the goals of the 21st century’s education is to bring school closer to real life, while placing the focus on building transferable competences, useful for students’ personal and social development. To integrate means to make connections, to coordinate, to blend, so that the final result reflects harmoniously the various components and provides a holistic vision of the topic of study. The interdisciplinary approach to education crosses the barriers of individual fields of study, and the contribution of each subject is paramount for a unitary perspective over any proposed theme. Integrated teaching and learning are prerequisites for the development of personalities perfectly adaptable to today’s society.

STRATÉGIES MÉTHODOLOGIQUES STIMULANTES
DANS L’APPRENTISSAGE ACTIF
L’apprentissage constitue un acte social qui conduit à la transformation des représentations mentales des individus. Depuis quelques décennies même, les spécialistes dans la formation humaine affirmaient que l’utilisation seule d’une pédagogie transmissive conventionnelle (exposé, conférence, etc.) orientée de préférence vers la quantité de connaissances, mène souvent à l’échec. Il est souhaitable d’adopter des stratégies didactiques orientées vers l’élève, qui tiennent compte des acquisitions et des expériences de chacun, de manière à réussir à former des compétences désirables à une bonne insertion sociale. L’approche euristique, l’apprentissage par découverte et l’apprentissage par résolution de problèmes représentent seulement quelques stratégies méthodologiques stimulantes qui constituent le thème de notre article. Celles-ci rendent le processus instructif-éducatif plus efficace et plus flexible, et l’apprentissage beaucoup plus durable.

O NOUĂ METODĂ DE DETECTARE A PLEOAPELOR
PENTRU SISTEMUL DE RECUNOAȘTERE A IRISULUI
This paper presents a new method for detecting the upper and lower eyelids. The method is called Refine-Connect-Smooth (R-C-S). It consists of three algorithms, Canny edge detector, Refine Edge Map (REM) and Connect and Smooth Edges (CSE). The algorithm is applied after the iris extraction stage therefore any incorrect detection of the eyelid will not decrease the accuracy of iris localization. The application of the method to CASIA database images version-1.0 has shown reasonable accuracy compared to previous methods of eyelid detection. For upper eyelid the accuracy reached 87.3%, while for lower eyelid the accuracy reached 99.2%.

E-LEARNING USED IN TEACHING AND ASSESSMENT Using computers as an educational teaching process in the act of teaching and learning, affecting both, the teacher teaching and learning activities of students. Pedagogical issues related to this aspect is contained in formulas of this type of computer assisted instruction and computer assisted learning. The two aspects, instruction and learning are in fact correlative first it aims mainly the teacher, the second, the student. In a speech condensed we could say that CBT is the way in which interaction between teaching and the learning of teachers and students, is mediated by the presence of the computer, considered as auxiliary technical, intended to increase and optimize teaching positions, work reception and information retrieval teaching by students.

UNE PERSPECTIVE PSYCHOLOGIQUE SUR
L’INSTRUCTION ET L’APPRENTISSAGE ACTIF
A partir du XXe siècle, de nombreux chercheurs se sont posé des questions sur le processus d’apprentissage. Ce processus a représenté une des préoccupations majeures de l’homme tout au long de son existence, qui a essayé pas seulement à apprendre, mais aussi à comprendre comment doit-il apprendre. Le syntagme «la théorie de l’apprentissage» définit un ensemble de lois ou de principes qui décrivent et expliquent la manière dont l’apprentissage se produit. Tout le monde a entendu parler de Pavlov et de son chien, et la plus grande majorité du corps didactique a pris connaissance des études et recherches réalisées par Piaget sur le développement ontogénétique de l’enfant et de l’adolescent. De nos jours, les théories cognitives et constructivistes, assez connues par les enseignants, ne se concrétisent pas toujours dans le curriculum éducationnel, l’enseignement, et surtout l’évaluation, restant tributaires au béhaviorisme.

OCTOBER 2018, 20 YEARS OF THE ESTABLISHMENT
OF THE ROMANIAN STANDARDIZATION
ASSOCIATION – ASRO
The beginnings of standardization in Romania date from the period preceding the Second World War, the first national standards being adopted in 1937-1938 within the General Association of Engineers of Romania – AGIR. The Military Circle in Bucharest, October 2, 1998. According to Government Ordinance no. 39/1998 (as amended by GO no. 44/27 July 1998), on this date was held the General Assembly for the establishment of the Association of Standardization in Romania – ASRO, a legal entity of private law, with a legal status of a non-lucrative association, on the basis of Law no. 21/1924, the association comprising 106 founding members.
Through this institutional reform in national standardization, alignment with European norms has been achieved, transferring the responsibilities in the field to those who are the main beneficiaries of this activity.
