The cadastre and the land book form a unitary and mandatory system that ensures technical, economic and legal records of all the properties on the territory of the country. This paper includes the presentation of the operations necessary to prepare the cadastral documentation for detachment in two lots, using UAV photogrammetric technology. The studied area is located in the suburbs of Valea Ierii locality, with an area of 212353 sqm. The main part of the project was based on the use of the UAV photogrammetric method to survey the area. At the same time, two GNSS receivers were used to complete the photogrammetric measurements. Control and verification points were premarked on the ground, the coordinates of which were determined by the real-time kinematic GNSS method. This operation was followed by performing the photogrammetric flight using an UAS platform. The flight lasted about 17 minutes, covered an area of 29 ha and 288 frames were captured. The front overlap between photos was set to 75% and the side overlap to 65%. New technologies for taking frames and processing them have been adopted, through methods that involve a low cost and a shorter time to perform specific operations.
3D building models are widely used in many applications. The use of terrestrial laser scanning and UAS photogrammetry for 3D modelling is a popular practice especially for constructions with complex architecture. The present article presents an example of using these technologies successfully for 3D modelling of the Episcopal Cathedral of the Holy Trinity from Baia Mare, Romania. A number of 51 control and verification points were determined by the closed circuit travel method and the intersection method. All measurements were processed in Terramodel software. The control points used in the georeferencing of the scans were materialized by metal stakes and the verification points were materialized by reflective targets. Depending on the construction configuration, the field of view and the minimum/maximum scanning distances were subsequently set. A total of 45 scans were performed to model the entire cathedral. The photogrammetric flight was performed in RTK mode, with corrections being transmitted from the DJI D-RTK-2 Mobile Station base to the RTK drone. All retrieved frames had geolocation and frame orientation elements recorded by the IMU module. A total number of 222 photograms were taken, as a result of a double grid photogrammetric flight, with the camera oriented at 60 degrees, but also as a result of manual acquisition by performing orbital flights at different heights: an orbital flight on the ground floor, an orbital flight at the level of about 40 meters and an orbital flight around the tower.
The article presents the results of a study conducted to assess change in depression severity, and modification in the kynurenine pathway at participants. Presently, depression is one of the most regularly encountered mental illnesses. Research based on experimental studies indicated the beneficial effects of activities conducted in nature are reducing self-reported anger, fatigue, anxiety, stress and depression. The present study was conducted by measuring depression on both the subjective (Beck Depression Inventory) and the objective (spectrophotometric analysis) levels, to obtain more relevant information regarding the real change in depression levels, during the therapeutic horticulture intervention. Consequently, depression is assessed with the BDI doubled the data by assessing the levels of kynurenine and kynurenic acid obtained from biological samples. Results indicate that the levels of depression measured with the BDI have significantly decreased after the Therapeutic Horticulture Sesions. An even better result regards the fact that the significance of this change was not only statistical, but also clinical. Analysing the kynurerine and kynurenic acid concentrations, differences were observed amongst subject during the research study.
The field of constructions has evolved extraordinarily in terms of measurement techniques, requiring increasing accuracy. This has led to the creation of new specific technologies, and implicitly measuring instruments. The range of classical geodetic measuring instruments has been completed with new high precision instruments, even in the field of physics or machine building. The use of geodetic measurement methods in the field of Engineering Topographic Measurement Techniques involves, in addition to ensuring precision requirements, the choice of appropriate devices and technologies. This choice is imposed both by the previous precision calculations, starting from a maximum permissible deviation given, and by the knowledge of the execution and assembly technologies. The purpose of this paper was to study the effect and also the impact that new technologies had on the main measurement activities, and of course on measurement techniques. This review article summarizes, analyzes and discusses the current state of primary research in terms of the impact of current or developing technologies on geodetic techniques. The global corpus of primary research is growing at an unprecedented rate. It is difficult for most researchers to grasp the state of the art of a topic. A vast number of bibliographic references were taken into account, on which analyzes were performed.
Along with the development and improvement of measuring technologies and techniques in recent times, new methods have appeared to model and monitor the behavior of land and constructions over time. The main purpose of this research was to develop a new methodology to model and monitor large buildings in a non-invasive way. The methods proposed in this research are non-destructive and can be used to monitor the behavior of buildings over time. A method of comparing point clouds obtained using terrestrial laser scanning combined with aerial photogrammetric methods was used in this study. The advantages and disadvantages of using non-destructive measurement techniques over the classic methods were also analyzed. With a building located in the University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca campus as a case study and with the help of the proposed methods, the deformations over time of the facades of that building were determined. As one of the main conclusions of this case study, it can be stated that the proposed methods are adequate to model and monitor the behavior of constructions over time, ensuring a satisfactory degree of precision and accuracy. The methodology can be successfully applied to other similar projects.
