The impact of the projectile-plate is a complex phenomenon that is analyzed through analytical methods, based on simplifying hypotheses. In addition to the use of empirical laws, these aspects of the projectile-plate interaction and the effects on the structure are studied using numerical methods. This article presents the numerical evaluation of the behavior of a monolithic plate on impact with a rigid projectile using element-free Galerkin method and is shown the evolution of the impact with its effects (deformation with perforation of the plate). Also, an analyze of the variation of the total energy of the plate, kinetic energy of the bullet and bullet velocity over time are presented.

This paper represents AFAHC's conception of the beginning of digitization in the academy. The poor digitalization in the institution has made itself felt during the pandemic. The paper is a brief summary of what has been done over the course of a year to mitigate the effects of a weak digitization in the teaching/learning process. The beginning of solving the problem of digitalization, of understanding the digital educational process was made with the submission by a consortium with 4 partner universities of a project under the action Partnerships for Digital Education Readiness of the Erasmus program that is talked about in the paper.

UAV systems used automated pilots which can be configured based on the mission. The entry level market for this type of systems is not focus mainly on fixed-wing configurations. On this paper we asses, develop and simulate missions for an automated piloting system, built on a Cube Orange architecture. The flight controller is mounted on a fixed-wing twin-engine airplane built using additive manufacturing technologies. For the management and simulation of UAV mission we use Mission Planner, and open-source software from ArduPilot. The missions is simulated to obtain an improvement of the automated piloting system, evaluate the terrain from the flight path, avoid dangers, keep out of restricted areas and find the optimal routes. .

Enveloping a wide-range spectrum of political, cultural, and ethical aspects, the power distance index essentially summarizes the acceptance of hierarchical structures. The number of micro ecosystems in which hierarchy and power-centered forms of organization prevail is undoubtedly large, given the fact that authoritarian regimes have been mostly abolished and invalidated during relatively recent history, and many people are still unconsciously reminiscing on their unwritten rules of conduct. This paper intends to take a closer look into the impact that various power distance index values have on organizational culture, with multinationals being the niche thoroughly studied. By analyzing official performance reports in correlation with dr. Geert Hofstede’s premises, the author intends to give insight into how overall worker performance is affected by autocracy, inequality, and responsibility centralization, which are all consequences of high-power distance indexes.

Thermal properties of surface, Earth’s surface energy balance and atmospheric conditions effect the land surface dramatically. Local and global change continues in the Earth’s climate since the industrial era continues. The urban heat island (UHI) represents the phenomenon of higher atmospheric and surface temperatures occurring in urban area or metropolitan area than in the surrounding rural zones due to urbanization. UHI is most noticeable during the summer and winter. The main cause of the UHI effect is from the modification of land surfaces. In this research was using MODIS and SENTINEL data. From SENTINEL images was extracted coherence maps to determine values of this parameter in areas where UHI was notice. Coherence for SUHI range from 0.20 to 0.89 for day and varies for night between 0.23-0.89.

Diplomacy has emerged in interstate relations as a mechanism that facilitates the achievement of state objectives, with the task of promoting and protecting state sovereignty. It has had to be reinvented with every important discovery in world history and with every substantial change in the field of communication. The fourth industrial revolution changed the whole panoply of interpersonal and interstates relations, having an important effect on the way international relations unfolded. The emergence of 24/7 news networks, social networks, blogs and streaming has led diplomacy to enter a new stage of its transformation and adaptation to the realities of the contemporary world, giving rise to the so-called digital diplomacy. In this article cyber diplomacy is described from its communicational dimension point of view underlining its importance for assuring national interest of states.

In this article we describe the results obtained in an activity of evaluation of a personal development program addressed to students in the first year of study. It was carried out within a project financed by the Scholarship Scheme for Universities, concluded between the Ministry of National Education through the Management Unit of Externally Funded Projects and the Faculty of Electrical Engineering, Energy and Applied Informatics, “Gheorghe Asachi” Technical University of Iasi. The specific objectives of the project pursued three intervention components: motivation (M), networking (R) and workload (V). These have been directly correlated with other identified aspects (individual failure, academic failure) that lead to school dropouts and low academic performance. In order to achieve the objectives, the project presented a proposed activity plan for a target group of 80 students for one year of implementation). The activities proposed within the project represent punctual educational interventions on the factors that influence school dropout and academic performance. The evaluated program, the results of which we present here, was subordinated to the objectives related to the motivation of the students and their relationship skills and pursued personal development through creativity and socio-emotional education in students. This dimension of the programme was chosen because a major need existing on the labour market is the need to educate young people to have the attitude of a winner and to find solutions to problems .The behavioural acquisitions of the students, within the personal development programme through creativity and social-emotional education were: flexible, generative thinking in solving problems; acquiring coping strategies; optimisation of personal and academic life.

The paper aims to determine the optimal geometry, the control law and the operational limits of a supersonic air inlet; its operation control consists of its central cone positioning, with respect to the flight Mach number, keeping in sight the necessity of a suitable parameters’ distribution into engine’s combustion chamber. Inlet’s optimal architecture shall be determined (based on an algorithm regarding the maximization of the total pressure recovery), using basic planar geometry principles. Based on the optimal geometry of the inlet, its flow rate characteristic and its control law, as well as inlet’s operation limits were calculated and graphically represented.
