Monitoring the behavior of earth dams over time requires that they be permanently equipped with their own tools and control points. Monitoring is performed according to the importance category of the objective, control parameters, but also the specific conditions of the location. The paper presents a modern way of tracking structural deformations in the case of earth dams, owned by private owners, in order to assess their operational safety. The article presents three earth dams of different categories of importance (B, C and D), to analyze how to monitor each objective. The main study area is represented by the Piscicola Podi?u accumulation located on the Valea Oii river in Ia?i county. For the location of the earth dam, measurements were made for the creation and monitoring of the local geodetic network. The network consists of reference points (S1, S2), station points (B1, B2, B3, B4) and control points (P1-P11) located on the studied dam. The way of working involved several stages. In the first stage, the site recognition and the monitoring requirements of the dam stability parameters were performed. In the second stage, the conditions for carrying out the measurements for drawing up the situation plan and designing the geodetic monitoring network were analyzed. In the third stage, measurements were performed for the design of a local GNSS geodetic network. The purpose of this paper is to design and analyze GNSS measurements in the monitoring of earth dams with modern technologies.

Analyzing the evolution of the territorial organization process in the Republic of Moldova, we can mention that in a short period of time, land reforms have greatly influenced the sustainable use of land resources. The reason being the transfer of state-owned agricultural land to private property or rather, the division of land into small plots, which led to the impossibility of sustainable use of land resources. This reform has been inevitable and economically and socially justified and has led to a number of problems with the sustainable use of land resources, such as the disappearance of crop rotations, the maintenance and / or improvement of soil fertility, and the lack of an institutional system and the normative framework for the sustainable organization of land resources.

In recent years, it is necessary to involve as many specialists from different fields as possible, who need significant data interoperability to carry out expropriation projects, due to the increase in complexity of projects in the field of road infrastructure. The realization of these projects is strongly influenced by the integration of geospatial data using GIS (Geographic Information System) technology. There is the possibility of managing these geospatial data in GIS for the efficient exploitation of the data obtained from the measurements within the road infrastructure projects, through surveying methods, using total stations respectively GNSS receivers. GIS have a very important contribution in the evidence, management and planning of processes through the automated workflows. The applicability of GIS is significant in cadastre, utilities, urbanism, land planning, taxes, city halls and regional and national institutions. The data managed in GIS can have geospatial reference, so that data and phenomena can be exploited, analyzed, and interpreted in a spatial context. The expropriation aims to carry out works of national, county, or local interest. The expropriation procedure is the legal operation that has as main effects the forced transfer of an asset from the private property of natural or legal persons to the public property of the expropriator, followed by the payment of a compensation to the affected assets owners. In this article, a case study was approached for a public utility work of national interest "Oradea Ring Road Connection (Calea Sântandrei Roundabout) – A3 Highway (Biharia)" which is located on the administrative area of Oradea.

Every citizen of the Republic of Moldova has the right to property and protection from the state, for this reason the registration of land rights in the Republic of Moldova is mandatory. The Republic of Moldova develops land reform and takes concrete measures to protect the rights over land. For this purpose, the Register of Real Estate was implemented. Land rights protection was and is the first basic function of the registration process, so the registration process is a mechanism for protecting land rights.

In the technological age, computerization becomes a key factor, both in the rationalization of the work schedule and in the provision of services and information, factors that help to achieve as efficiently as possible the ongoing projects. GIS technology is increasingly becoming a necessity for a number of companies and institutions working with geospatial data. CAD projects are also currently helping to develop each industrial sector with more accurate data, depending on their requirements, including architectural and construction companies, installation management, utilities. These two technologies, viewed in a unitary way, largely complement the need for information when drawing up a work plan. From this point of view, it is quite clear from the last few years that the interconnection of GIS and CAD data demonstratively improves the operability and elimination of errors at the level of projects of great importance, and not only. In this article it is aimed to highlight how to use and integrate 2D and 3D data with the help of GIS-CAD technologies. It was chosen a dataset related to the cadastral plan of the intravilan of Ceamurlia de Jos, Tulcea county, a dataset that was imported into GIS and CAD software products.

This thesis presents a modern monitoring model of the geodetic parameters specific to dams made of earth and rock. The monitoring of dam components movements in the horizontal plane is currently carried out by the micro-triangulation method. The optimization of the monitoring process geometrical parameters for water accumulations dams requires the use of modern equipment and technologies. They allow a faster retrieval of data and its immediate processing with high-performance analysis programs. This reduces the time between measuring the formation and making the intervention decision. The studies and researches carried out have indicated the development and application of a real-time monitoring system of the geometrical parameters at Gura Apelor dam. The proposed monitoring system uses a set of modern equipment including Leica Nova TM50 total stations, 360° prisms and GNSS antennas. The monitoring equipment is supplied with sensors for atmospheric information for the correction of measurements.

One of the reasons for the elaboration of this work is the desire to implement modern methods and techniques of cartographic analysis in order to obtain results that express both visually and in terms of value the level of accessibility of the population to various public administrative institutions in Alba Iulia, as well as their ability to act in different situations. This is why we consider it appropriate and topical to carry out a study that classifies a specific geographical area into a certain risk category in terms of accessibility to a specific emergency situation.

Urban issues related to energy performance are a top priority of the European Agenda, as a significant share of the intense effort to reach climate-neutrality by 2050 (European Commission, 2019). The European” Green Deal” set the target of 55% greenhouse gas emissions reduction by 2030, which requires new buildings to meet energy and environmental performance thresholds of the Nearly Zero-Energy Buildings (nZEB) (Directive 2010/31/EU) and also increase in deep renovations of existing buildings stock by giving priority to energy efficiency in order to achieve nZEB performances (Directive EU 2018/ 844). Sustainable planning plays an important role in the process of transformative urban adaptation (EEA Report 2016) by promoting the nZEB concept as an energy reconfiguration strategy of buildings, urban areas and settlements, having as goals of minimizing the impact on the quality of natural environment and ensuring normal indoor living conditions. It is proposed to submit a decision-making tool for energy assessment at the urban area level, called nZEB Urban Energy Atlas, which describes the methodological path from the current state assessment until the adoption of optimal scenarios for deep renovation of existing buildings stock.

Beside positive desired direct effects of industrial activities having the goal to increase humanity quality of life by developing, applying and using diverse technologies, these can also have negative, undesired impacts on environment and society. In this regard the concept of sustainable development has been recognized and accepted as being the possible solution for the arisen complex global environmental, economic and social problems, which humanity is actually confronted with. To assure the transition of our society toward sustainability technical, economic, environmental as well as socio-political aspects have to be simultaneously considered as much as possible in decision making processes. For engineers this means to lead technology assessment studies and to comprehensively assess industrial applications as well as correlated necessary infrastructure, especially existing and planned buildings. From this reason it is very important to develop analytical tools to analyze and assess buildings from the point of view of their potential impacts with regard to shaping sustainable cities. One of these tools already applied in technological field is the Life Cycle Assessment. In this paper the applying possibility of Life Cycle Assessment in the context of diverse buildings will be presented and debated in order to assure shaping sustainable cities.

Using a series of maps rendered via ArcGIS Pro, the present article aims to make a comparison of the number of Ukrainian refugees fleeing the war between Russia and Ukraine during 2022 and the number of Arab refugees who left their countries between the years 2011 and 2021, following the so-called “Arab Spring” conflicts. The techniques used for creating the maps included dot and bivariate dot density mapping, as well as a bivariate color and chart symbol mapping. For an improved highlighting of the represented phenomenon, it was proposed to have it symbolized by dots of similarly colored shades, from the lightest to the darkest, depending on the number of refugees hosted by each country. The resulting maps are intended for the general public to provide an overview of the population displacement caused by war.

The paper presents a finite element formulation based on the Generalised Beam Theory (GBT), for the analysis of elastic buckling behaviour of conical shells under various loading and boundary conditions. The GBT approach provides a general solution for 1st and 2nd order analysis using bar elements capable of describing the global and local deformations. Because of the cross-section variation specific to conical shells, the mechanical and geometric properties are no longer constant along the bar axis as it is the case of cylinders and prismatic thin-walled structures. This formulation is validated by comparison between GBT results and values obtained by means of shell finite element analyses. The study covers simply supported conical shells under axial compression. The study also presents a possible practical application on oil platforms.

: Being at the stage of 20 years of operation, the agricultural land market in the Republic of Moldova collided with several socio-economic problems, which limited (partially) the dynamic development of this market. Although in the process of identifying the market prices of agricultural land in the Republic of Moldova, different evaluation methods are widely used, the method, based on comparable prices, is the preferable one, the most often used. At the same time, this method is the most dependent on the stability of the purchasing power of the national currency - the Moldovan lei. The sudden increase in the level of inflation in the last two years has disorientated the participants of the land market and negatively influenced both the number of transactions for the sale and purchase of agricultural land, as well as the area of land included in the market circuit. The deeper analysis of the current state, as well as the elaboration of reasoned recommendations, regarding overcoming the crisis situation on the agricultural land market in the Republic of Moldova, is the main purpose of this publication.

Considering the climate change, the medium and long-term energy objectives of the European Union, regarding climate neutrality require significant reductions in energy consumption and implicitly in CO2 emissions related to the exploitation of buildings, and at the same time the promotion of energy production technologies from renewable source; the building envelope can become the support for the placement of these technologies both in the case of new constructions and in major energy renovation projects. The tools used for the purpose of sustainable urban planning with the objective of promoting new buildings with nearly-zero energy consumption but also with reference to the energetic reconfiguration of the existing built stock, such as the nZEB Urban Energy Atlas (Izabella Marin Lazar 2022) include the possibility simulation in accordance with the proposed intervention scenarios and specific climatic conditions of the amount of energy from renewable sources that can be produced on site and the contribution of these sources to the energy balance of the urban area.

Surveying technology currently offers us a multitude of benefits and can be used in many fields of activity to create a more efficient way of working for people. This project aims to describe the process of 3D reconstruction of a mining site with UAV technology. The first step means performing the actual flight in the targeted perimeter with a drone (or UAV – unmanned aerial vehicle) equipped with a camera to capture images of a site from different vantage points. Out of these images, a photogrammetry software can recreate geo-referenced 3D maps of the mining site. The processing of the cloud of points collected with the help of the drone is an important step of this project. Mining operators can also easily extract the precise volume of stockpiles or areas to be excavated. By providing thousands of data points for one stockpile, drone surveys are far more accurate than surveying with total stations.

Databases and new technologies offer the opportunity to recover the gaps with the European Union and with the countries that understood earlier the role of new technologies in the modernization of public services. In this context, ANCPI makes efforts regarding the digitization of services, by making available users, natural or legal persons, new ways of connecting, requesting and charging for the requested services, through the e-terra, e-payment, etc. applications. The purpose of this article is to present some aspects related to the use of the new service codes, related to the approval and reception of the registration documents in the Land Registry.
