BUSINESS PROCESSES AND OCCUPATIONAL PROFILES CHALLENGES FOR TOMORROW-S INDUSTRY WORKFORCE

(STEF92 Technology, 2021-12-20, Maria Ioana Vlad Sandru, Alina Răduțu, Ion Nedelcu)

Show more

This article offers an innovative method for deriving curricula for tomorrow’s workforce in the geospatial sector, considering the market requirements through modelling business processes, identifying and analyzing occupational profiles. The idea behind this approach reveals business processes models described by workflows of tasks that workforce needs to master in their daily work. In addition, business processes show who is involved in projects and needs to communicate with one another, and how the information i...

CHANGE DETECTION TRENDS IN URBAN AREAS WITH REMOTE SENSING AND SOCIO-ECONOMIC DIAGNOSIS IN BUCHAREST CITY

(STEF92 Technology, 2021-12-20, Alina Răduțu, Maria Ioana Vlad S ndru, Ion Nedelcu, Violeta Poenaru)

Show more

Urban areas are very dynamic environments, subject to continuous expansion and growing population, with land use changes influenced by the needs and dynamics of the population. Using remote sensing techniques applied to Sentinel-1 GRD images, some change detection patterns could be revealed for Bucharest city, for a period of three years (2016-2019). As the largest city in Romania, the main university center and the most important industrial and commercial center, Bucharest offers a wide range of educational, inve...

NEW PROPOSED SOLUTION FOR MINIMIZING THE EFFECTS CAUSED BY REPEATED FLOODS

(STEF92 Technology, 2021-12-20, Victorita Radulescu)

Show more

Romania faces floods every 2-3 years, followed by human and animal losses, and large flooded agricultural areas. There are rivers such as Siret, Crisul Repede, Cri?ul Negru, Ialomita with non-rehabilitated areas that have systematically caused damages in the last decade. Based on the latest measurements, the real transport capacity of natural course in high flow conditions and flood risk was estimated. In recent years, after the massive floods recorded in 2005, 2008, 2012, and 2018, there have been uncontrolled de...

NUMERICAL MODELING OF INFILTRATION THROUGH DAMS AND LATERAL DIKES REALIZED OF LOCAL MATERIALS TO REHABILITATE THEM AND INCREASE THEIR LIFESPAN

(STEF92 Technology, 2021-12-20, Victorita Radulescu)

Show more

In Romania before 1990, over 600 hydro-power plants were built with dams and lateral dikes made of local materials. In order to be completed as soon as possible and with material savings, the protection screens were improperly executed. In many cases there is no continuous protection screen along the dam and in its vicinity, but only from place to place, intermittently. The same problem is with the lateral dikes of the lakes. In these conditions, at the hydroelectric power plant commissioning, the infiltration imm...

SOIL QUALITY, A PERMANENT PROBLEM IN THE MANAGEMENT OF CRITICAL AREAS FACED WITH ACCIDENTAL OR CONTINUOUS POLLUTION

(STEF92 Technology, 2021-12-20, Bogdan-Alexandru Radulescu, Victorita Radulescu)

Show more

Unfortunately, soil is a non-renewable resource that fulfills several vital functions such as food/biomass production, storage, filtration and transformation of mineral or biological substances, source of biodiversity and habitats, etc. Due to the development of industrial activities outside the localities, in many areas the soil is degraded. Among these degradation processes can be mentioned degradation of organic matter, contamination, soli salting, and erosion. This paper is dedicated to the presentation of the...

SOURCE PARAMETERS, CLUSTERING AND SCALING PROPERTIES FOR THE VRANCEA (ROMANIA) SUBCRUSTAL EARTHQUAKES RECORDED BETWEEN 2016 AND 2018

(STEF92 Technology, 2021-12-20, Anica Otilia Plăcintă, Felix Borleanu, Emilia Popescu, Mircea Rădulian)

Show more

The Vrancea zone, located in Romania, at the sharp bend of the Southeastern Carpathians, is a well-defined seismic region in a continental convergence area with unique properties and generating the most destructive subcrustal earthquakes in Europe. The seismicity is concentrated in a confined, high-velocity, focal volume at 60–200 km depth range. The increasing number and quality of waveforms digitally recorded in the last time by the National Institute for Earth Physics (NIEP) provide the opportunity to better co...

THE INFLUENCE OF ENVIRONMENTAL CONDITIONS ON THE DOLPHIN POPULATION IN THE ROMANIAN COASTAL AREA

(STEF92 Technology, 2021-12-20, Victorita Radulescu)

Show more

In recent decades, there have been some changes in the salinity, quality, and average temperature of the Black Sea water. Among other modifications, there was a significant decrease in the dolphin population on the Romanian coast. The decrease in the number of species Tursios trucantus ponticus, Delphinus delphis ponticus, and Phoococena phocoena relicata species found in this area required more detailed research to obtain information about their living conditions and migration. Located at the top of the ecologica...

THE INFLUENCE OF WATER LOSSES IN THE OPERATION OF THE WATER SUPPLY SYSTEM IN THE ROMANIAN BIG CITIES

(STEF92 Technology, 2021-12-20, Victorita Radulescu)

Show more

In many cities from Romania, the water supply systems are very old, sometimes having over 60 years after their commissioning. Under these conditions, permanent large leakages are recorded. They are significant for the operator, influencing its economic performance and operating costs. The water supplier must understand the mechanism of water leaks and their influence on the performance of distribution network. The losses recorded by the system are unused for the purpose for which the supply was made, representing ...

THE SITUATION OF THE ROMANIAN COAST LAKES, AN OLD PROBLEM REQUIRING RAPID SOLUTIONS

(STEF92 Technology, 2021-12-20, Bogdan-Alexandru Radulescu, Victorita Radulescu)

Show more

Lakes on the Black Sea coast are the direct result of soil erosion and marine or hydrographic accumulations, consequence of the specific evolution of the nearby sea basin. They depend on the variations in groundwater levels, rainfall or other hydraulic surface sources. In recent decades, as a result of many small, local earthquakes, some deep currents have appeared. Lakes as origins, are of fluvial-marine estuary, lagoons or artificial. Many of them are tourist attractions, due to the specific microclimate establi...
