Information Technology-assisted Teaching in the Field of Geodesy: Mentor – Debutant Co-operation

AbstractThe purpose of this paper is to analyse and asses the information technology-assisted teaching process of a debutant teacher, by following the advice of a mentor and using new teaching methods in the subject area of algorithms for geodetic networks analysis within the framework of the mentoring program “University school for initial and continuous training of the teachers and trainers in the field of technical and engineering specializations – DidaTec”, POSDRU/87/1.3/S/6089. As a result of the mentor – debutant meetings, evaluation reports were prepared by the debutant establishing the adequate teaching process and methods to be used; the design and development of a seminar material in electronic form, with the specific structure of blended learning and e-learning

Computerized simulations and modelling for evaluation of ballistic and security parameters of explosives for civil use

Explosives are chemical compounds - substances or mixtures of substances that have a large amount of energy and which under the influence of external actions decompose suddenly, violently with the release of heat and the formation of gases capable of performing a mechanical work. Due to their specific characteristics, these products are used, both in the civil field and in industry, for the execution of works such as: extraction from the massif, in mines or quarries of useful rocks, execution of mining works (galleries) for opening and preparing deposits for exploitation, tunnels, wells, road constructions, railways, canals, demolition of foundations / civil / industrial buildings that have become unusable, geophysical-seism metric surveys, etc. Research in the field of use of explosives for civil use in various industrial and civil applications requires in-depth knowledge of areas such as the phenomenology of explosion, the behaviour of materials in shock waves, the dynamics of structures, seismic engineering, etc. The design of these types of processes requires the consideration, with a relative approximation, of the degree of danger due to the design of fragments resulting from detonation, vibrations, pressures, tensions created in the space affected by the explosion, generation of explosion gases, etc. legislation in force, being an important indicator regarding the classification, handling, storage and transport in the assessment and management of the risks related to these operations. The paper presents a series of computer simulations, both of the ballistic parameter regarding the working capacity of the explosives, and of the security parameter regarding the impact sensitivity

WebGIS Solution for Urban Planning Strategies

AbstractIn line with the objectives established by the “European capital of culture” initiative, the entire community is involved in embarking socio-economic and infrastructure projects supported by an information platform which ensures efficient data management for the municipality. This platform should provide a good visibility of the candidate city in the context of enhancing the contribution of culture to its long-term development in accordance with its priorities and strategies. In particular, an important role is played by the implementation of a spatial data geoportal at Local Administration level (Timişoara City Hall) to streamline the data workflow and provide easy access to it in order to increase the visibility of cultural and historical heritage of the municipality. The need of this geoportal arises from the fact that Timişoara has the widest architectural heritage area in the country, of important value to both Romania and Europe. The preservation of this cultural heritage is a duty for the authorities and also for the owners. The present paper brings forward proposals and trends in implementation of a dedicated geoportal for the management of heritage objects to complete the existing urban GIS primarily aiming to contribute to fostering the urban planning and the sustainability of the “European capital of culture” project. This geoportal should include the 3D models of the cultural heritage objects for better preservation over time or restauration purposes and offer virtual tourism tours if they are made available by means of webGIS. That is why, the authors propose a webGIS solution in order to make the geoportal available on the City Hall's webpage. The actuality of the paper is given by the fact that preserving cultural heritage and historical sites represents an important issue that must be taken into account when urban planning projects are required for developing the model of urban growth

Geodetic studies with significant contribution to landslide monitoring in south-western Romania – area with high risk potential

Cilj rada je upoznavanje s geodetskim istraživanjima koja su usko povezana s modeliranjem odrona zemlje i moraju se primijeniti za trajno nadziranje područja u kojima dolazi do geomorfoloških opasnosti. Iako se ponekad nedovoljno cijeni doprinos geodeta nekim projektima za nadziranje odrona u svrhu razvoja sustava za rano upozorenje ili izradu karata s prikazom mogućih opasnosti, kako je navedeno u FIG radnoj grupi (2006) [20], i promatra ih se jedino kao dobavljače izmjerenih geometrijskih podataka, njihov je doprinos važan u modeliranju dinamičkih sustava, kao što su strateške konstrukcije (brane, visoke zgrade itd.) ili odroni zemlje te u interpretaciji podataka. Istraživanje ponašanja tijekom vremena nekog objekta zahvaćenog odronom uključuje geodetska mjerenja obavljena u ranije utvrđenim vremenskim intervalima primjenom najsuvremenijih tehnologija, koje omogućuju obradu i pregled tako dobivenih podataka u trodimenzionalnom sustavu. Uz to, cilj je postaviti okvir za oblikovanje i optimizaciju mreža za nadziranje biranjem optimalnih istraživačkih metoda.This paper aims at presenting geodetic studies that are in close connection with landslide modelling and must be used for continuously monitoring the areas affected by geomorphological hazards. Although sometimes the geodesist’s contribution to certain projects for landslide monitoring meant to develop early-warning-systems or risk maps is not adequately appreciated as stated in FIG Working Group (2006) [20] and he is only seen as supplier of measured geometric data, the geodesist has a significant contribution through his abilities regarding the modelling of dynamic systems, like strategic constructions (dams, tall buildings etc.) or landslides and data interpretation The study of how an objective affected by landslides behaves in time implies geodetic measurements performed at pre-set time intervals using state of the art technologies, which allow processing and review of data thus obtained in a three-dimensional system. Moreover, the goal is to set the stage for the shaping and optimization of monitoring networks by choosing the optimal research methods to be used
