    Following the interaction of a neutrino with saline environment, the Cherenkov cone will be generated. The electromagnetic effect of the Cherenkov cone is perpendicular to the cone generator and it has the energy directly proportional to the neutrino energy. In the saline environment, neutrinos with very high energies (noise – 115 dBm) can be determined. Investigation of these neutrinos will lead to the construction of a Cherenkov detector. The construction of a Cherenkov detector involves the design and the construction of a very large number of detection elements and of cascade amplifiers. Another necessary condition is to know exactly the distribution of the dielectric parameters of the saline environment. In order to know the distribution of the dielectric parameters of the saline environment, it is necessary to make a map of their distribution. Under these conditions, the number of detection elements will be optimized and also the optimal position of the future Cherenkov detector will be determined. In this chapter, we will present the methodology of calculating the detection elements and a method to determine the dielectric parameters. Measurements of attenuation of the propagation of electromagnetic waves in this environment will be presented. We will detail how to optimize a Cherenkov detector

    The National Cadastre and Land Registration Program that started in 2015 and is scheduled to be finished in 2023 is meant to ensure the systematic registration of all real estates in Romania, for the cadastral sectors of 3181 administrative territorial units. Some of the basic elements in favour of these changes are: the development of irrigation systems, rehabilitation of land developments works, the development of infrastructure projects for transport routes, unprivileged areas, etc. In this context, there are included all the administrative territorial areas where, at various moments in time, there have been conducted different hydro-ameliorative works and underground drainage systems have been implemented. In Suceava County, these works covered 55,100 ha and included 20 large systems and numerous local systems. The case study consists in the correlation of the graphic and alphanumeric database with the soil-land cartographic units that were identified in the Baia – Sasca hydro-ameliorative system. The mapping activity was conducted between 1976-1977 on a surface of 6,500 ha, and the hydrotechnical schemes were created in 1978-1980 on a total surface of 5,527 ha; from the total surface mentioned before, 1,806 ha also included a systematic underground drainage system with ceramic pipes. The cadastre and land registration activity from the six territorial administrative units of the Baia – Sasca system permited the correlation of the database into an integrated system. The present spatial distribution of the six territorial administrative units: Horodniceni, Cornu Luncii, Rădăşeni, Baia, Fântana Mare and Vadu Moldovei, includes 30,167 ha of the total surface of the agricultural and non-agricultural land

    The topographic measurements and the technical cadastral documents drawn up in time in Romania included several distinct stages. The main differences between them consisted in the society’s development requirements at that particular moment and the measuring technologies used. Law on Cadastre and Real Estate Advertising no.7/1996, with the subsequent modifications and completions, created the context for drawing up and implementing the unitary cadastre and land register system. This system includes 3,181 administrative - territorial units as follows: 103 municipalities, 217 cities and 2,861 communes, the latter one with 12,957 villages. At the same time, it was started the National Cadastre and Land Registration Program, estimated to be conducted between 2015 and 2023. The main objective of the program consists in performing systematic cadastral works considering the cadastral sectors in the administrative territorial units, so they can be registered in the land register. The cadastral documents drawn up on cadastral sectors indicate the measured surface as well as the real property right over the real estates. According to the present administrative - territorial organization of Suceava County, its 8,553 km2 include 114 administrative – territorial units, of which: 5 municipalities, 11 cities and 98 communes, the latter ones including 379 villages. Our case study tried to point out the real technical and legal situation of two cadastral sectors situated in the unincorporated area of Bilca commune, Suceava County. The two cadastral sectors that were identified and analysed cover 14.5134 ha (cadastral number 243) and 10.0668 ha (cadastral number 254), respectively. The limits of the real estates from the two cadastral sectors mentioned resulted from field measurements and their identification with the legal owners. The limits of the cadastral sectors were indicated on the basic plan sheet, scale 1:5000, nomenclature L-35-04-B-a-3-III and the control area 540.9816 ha

    The Application of Electromagnetic Sensors for Determination of Cherenkov Cone Inside and in the Vicinity of the Detector Volume in Any Environment Known

    The neutrinos of cosmic radiation, due to interaction with any known medium in which the Cherenkov detector is used, produce energy radiation phenomena in the form of a Cherenkov cone, in very large frequency spectrum. These neutrinos carry with them the information about the phenomena that produced them and by detecting the electromagnetic energies generated by the Cherenkov cone, we can find information about the phenomena that formed in the universe, at a much greater distance, than possibility of actually detection with current technologies. At present, a very high number of sensors for detection electromagnetic energy is required. Thus, some sensors may detect very low energy levels, which can lead to the erroneous determination of the Cherenkov cone, thus leading to information errors. As a novelty, we propose, to use these sensors for determination of the dielectrically permittivity of any known medium in which the Cherenkov detector is used, by preliminary measurements, the subsequent simulation of the data and the reconstruction of the Cherenkov cone, leading to a significant reduction of problems and minimizing the number of sensors, implicitly the cost reductions. At the same time, we offer the possibility of reconstructing the Cherenkov cone outside the detector volume

    Drawing up the numerical model for the field relief based on the detailed topographic elevations performed in the underground pipe drainage systems

    For The modern cartographic representations of field relief as plans and digital maps, and numerical models, respectively, require the existence of new topographic measurements made with modern methods. In this context, a series of hydroameliorative systems with underground pipe drainage are taken into consideration so that afterwards the fields can be exploited as agricultural fields. The case study included the execution of detailed topographic elevations on 210 ha that included a pipe drainage system. The area was situated in the Baia-Sasca, Suceava County, hydroameliorative system. For conducting the field works there were used GPS receivers, total measuring stations and the A class network of permanent stations from the GPS-GNSS national system. After the real time processing of the on field observations it resulted the plan metric and altimetric set of elevation points. Based on this set of points it was created the digital plan in the 1970 Stereographic projection system of coordinates and the numerical model of the relief in the normal heights system – 1975 Blank Sea

    UNHIDING FORESTED LANDSCAPES. THE ARCHAEOLOGICAL INDEX OF SOUTH-EASTERN CARPATHIANS

    Starting with late 2018, a new archaeological research project has been unfolding in the framework funded by the Romanian Governmental Unit for Research and Development (UEFISCDI) dedicated to top fundamental research, as one of the few winners of 2016 edition (the single to date) of ‘Complex Projects for Frontier Research’ competition. The Project, whose aims and methods will be shortly presented further, is entitled ‘Hidden Landscapes: Exploratory Remote-sensing for the Archaeology of the Lost Roads, Borders and Battlefields of South-Eastern Carpathians’ (HiLands). It implements a systematic and diachronic investigation of the historic strategic circulation corridors crossing the South-Eastern part of the Carpathian Mountains – the main gate used along ages by people transiting between Transylvania and the Danube or the Black Sea. In order to achieve such aims we have been exploring, starting from large scale LiDAR surveys, the circulation corridors’ diachronic archaeological fingerprint, preserved in the shape of  repeatedly fortified landscapes. LiDAR surveys have been carried on continuously since 2018, by airplane, but also with portable sensors based on SLAM technology. The results of the LiDAR explorations were enhanced by field surveys, geophysical prospections and pin-pointed excavations, in order to elucidate the nature of anomalies or better contextualize the significance and layout of the roads’ routes. The results of these activities are resumed in a constantly updated, open access, online data base of archaeological sites - The archaeological index of South-Eastern Carpathians (AISEC). The current contribution details the essentials of HiLands research (aims, concepts, methods), in order to introduce in the scientific circuit the AISEC’s functions and instruments, ready to be used as citable work.</em
