There are some current technologies that may be applied to rural sustainable development, such as new-generation photovoltaic panels and systems of passive heating of water.This paper presents an application of Analytic Hierarchy Process for selection of renewable energy sources and technology in context of Central Region of Romania. The option – solar energy have been evaluated based on selected criteria. The objective of our working paper is to analyze the renewable energy development policy in isolated areas of Romania. Renewable sources of energy play an important part in the sustainable supply of energy and in the sustainable economic and social development.Using a GIS model, the aim is to demonstrate which of the analyzed sources of energy is the most convenient to be used in a sustainable system, solar or electric network.

A LOW TE(A)CH APPROACH TO DIGITAL HUMANITIES

Author(s): Liviu Pop / Language(s): English / Issue: 1/2017

Technological fatigue is spreading due to the increased arrays of technological branches and the rapid pace of development. Keeping up with the latest and newest might prove not only difficult and tiring, but also not necessarily recommended to beginners in digital humanities. A more “back to the basis” approach might be more useful for students that don’t have technical backgrounds.

A SHORT HISTORY OF COMPUTER USE AT FACULTY OF PHYSICS – UNIVERSITY OF BUCHAREST

Author(s): Mircea Victor Rusu / Language(s): English / Issue: 2/2017

For physicists computing is a main activity. Starting from devising an experiment to problem solving with computer, from using mathematical tables to other aids to computation, physics has grown its strength by using each step the numerical computation. So, computing for researches as well as education was used and steadily improved by us, starting from first minicomputers to the last generation of computers and algorithms. In this presentation we will follow, in short, the evolution of computing, hard and soft, in physics at our faculty. We selected here the main field of interests that was connected with problems showing: programmed solutions, simulations and modeling, computer application and software during the time. Such a time recollection is interesting and surprises me as how diverse and far such activity was done. Examples will be from computation in tradition physics, to biology, chemistry, astronomy, medicine to data processing and visualization, data management, to create our own educational software and so on. The fields as nonlinear dynamics, complexity, chaos and fractals, as well as fluid dynamics, atomic, molecular or nuclear physics, earth or stellar physics, connected to improvement of the experiments and devices via artificial intelligence are some of our topics which will be exemplified here.

Abordări G.I.S. în analiza evoluţiei teritorial-economice a municipiului Reşiţa

Author(s): George Laurenţiu Merciu / Language(s): Romanian / Issue: 2/2012

Territorial and economic evolution of Reşiţa city is closely link to industrial activity. This also contributed to shaping its role as urban center as regional pole in the Banat Mountain. Favorability of natural environment (ground and underground resourses) competed with historical factors in the emergence and development of an important industrial center since at the begining of the XIXth century. Industrial activity influenced the development of two well contoured functional areas (residential and industrial). Territorial development stages of the city were closely related to the expansion of plants domains of Reşiţa that marked still visible differentiations in the urban landscape (colony districts of German influence followed by the modern working-class neighborhoods). The actual urban landscape of Reşiţa city is a mixt between vernacular architecture and the modern one.

Actual Approaches on the Water Utilities Data Models

Actual Approaches on the Water Utilities Data Models

Author(s): Ana Cornelia Badea,Gheorghe Badea / Language(s): English / Issue: 24/2018

In November 2017 the Technical Normatives about producing spatial datasets on public utility networks was approved and published by National Agency of Cadastre and Land Registration. Romania has undertaken the implementation of INSPIRE, so identifying the best ways to put it into practice is an essential step in the application of these rules. Currently there are developed models for water and sewerage networks, designed both using company software and open source software solutions. From cadastral and urban management viewpoint, it is very important that the utility networks to be correctly and complexly modeled, justifying the importance of presented analysis. Its importance is due to the fact that utilities networks are fundamental parts of the smart city concept, being integrated with the cadastral information. The implementation of concepts that lead to 3D modeling of standards-compliant utilities networks, while also offering open-source access, is a top priority, including at international level. The present article aims to analyze these models by highlighting their current status and defining important aspects.

Aerial Survey Test Project with DJI Phantom 3 Quadrocopter Drone

Aerial Survey Test Project with DJI Phantom 3 Quadrocopter Drone

Author(s): Tamás Jancsó,Peter Engler,Peter Udvardy / Language(s): English / Issue: 21/2016

The paper deals with the optimization of the aerial triangulation based on UAS images. The images were taken with a DJI Phantom 3 quadrocopter and they were measured in Photomod Lite ver. 4.4. The bundle adjustment was carried out twice; first in Photomod Solver and later in BINGO ver. 6.8. During the adjustment 14 ground control points were used and 31 points were calculated as new points. Using these new points we could compare the coordinates to the coordinates received from the high-precision field surveying measurements. From the coordinate differences the calculated RMS errors of horizontal coordinates are around one pixel size on the ground and to 2.5 pixels vertically. The final results showed us that a non-metric camera at low flight height with a quadrocopter can be used effectively and accurately at aerial surveys of relatively small areas.

Alimentarea cu apă în orașul Iași: influențe, rețea, tehnologie (secolul al XVII lea – jumătatea secolului al XIX-lea)

Author(s): Laurenţiu Rădvan,Andrei Melinte / Language(s): Romanian / Issue: 25/2017

The water supply in the town of Iași was a long-standing concern for the rulers of Moldavia, with beginnings predating the rule of Vasile Lupu (1634–1653). Due to the lack of sources, it is only when this prince came into office that we can benefit from more solid information: the first pipelines bringing water to the palace and the public bath (feredeu) were installed during his reign. The most significant investments were made in the 18th century when the foundation is gradually laid for a network and supply system. Major contributions were brought by princes Grigore II Ghica and Grigore III Ghica, and Constantin and Alexandru Moruzi, who used water from the sources in the hills outside the town. The inventory (attached to this study) taken by a committee in 1841 has revealed more details about how the network operated, and allows for a clear conclusion: the water supply system displays an obvious Ottoman influence. The craftsmen who had worked on capturing water and creating the water fountains in Iași were known to have come from south of the Danube, but we now have data confirming the idea that structural and functional elements from Ottoman towns were introduced in the water network of the Moldavian capital. The specialized terms (suiulgiu, cișmea, havuz, maslac, terezie, lichium, edirmeli) are Turkish in origin, and so is the way the system was designed.

An Overview on Space Time Cube Visualization in GIS

An Overview on Space Time Cube Visualization in GIS

Author(s): Ana Cornelia Badea,Gheorghe Badea / Language(s): English / Issue: 25/2018

Over the last years, the STC (Space Time Cube) visualization method has been analyzed in many scientific papers in the literature. The term STC cames from cartography, meaning a geographical representation where time is treated as the third dimension.This model was introduced by the Swedish geographer Hägerstrand at the end of the sixties. When datasets involve more than one dimension in addition to time are difficult to visualize. In a geovisualization environment, maps as digital representations are used to emphasize visual thinking about geospatial patterns, relationships, trends. Currently, GIS technology offers dedicated tools that lead to interesting viewing results using this method, the cube and its contents being automatically created from a database. We reviewed some functions on temporal data, used to view geospatial data sets in different ways. Also in the case study, an earthquake dataset was used, which was represented using the STC method, but also in the form of a temporal slider application.

Analiza digitală a reprezentării cartografice a orașului Sebeș din 1769

Author(s): Andrei Nacu / Language(s): Romanian / Issue: 27/2019

In the first decades following the annexation of Transylvania to the Habsburg dominions, the Austrian military engineers produced a series of topographic plans representing the Saxon cities of Brașov, Sibiu, Mediaș, Bistrița and Sighișoara. In the case of Sebeș, the smallest urban center of the Transylvanian Saxons, the first cartographic depiction was only completed in 1769, during a general survey of the seat [administrative subdivision] of Mühlbach/Sebeș. This limited survey preceded the mapping of the entire Grand Principality of Transylvania (First Habsburg Military Survey), which took place between 1769 and 1773. The article presents the analysis of the 1769 cartographic representation of Sebeș using the open-source software Quantum GIS 3.4. After a scanned copy of the map was georeferenced and digitized, the investigation proceeded with a comprehensive description of the historical topography of Sebeș. We examined the roads, the hydrographic network, the inner city with its Medieval and Early Modern fortifications, the churches and cemeteries, the suburbs, the vineyards, gardens and orchards, as well as the mills and dams on the Sebeș river.

Author(s): Tadeusz Bocheński / Language(s): Polish / Issue: 1/2017

The aim of the study was to analyse the operation of passenger railway stations and station buildings in Poland, aswell as the changes that occurred in connection with investments in infrastructure. The studies covered active passenger andrailway stations as listed in the train timetable 2016/2017 and included comparison to the timetable 2009/2010. Two researchquestions were asked: about the layout of passenger stations and active railway stations in Poland and about the impactof investments in railway infrastructure carried out in the years 2010-2016 on the number of passenger stations and on thecondition of railway stations.In 2017 there were 2497 active passenger stations, located in 2063 localities. An average density of passenger stations inPoland was 0.80 station per 100 km2 and 0.65 station per 10,000 residents. At 622 passenger stations there were active stationbuildings, i.e. open for travellers. On many station buildings the scope of service for travellers was limited to a waiting room.As a result of investments carried out in the years 2010-2016, about 100 railway stations were modernised and several morewere renovated. Moreover, about 50 new passenger stations were built. During that time, several processes were taking placesimultaneously: closing passenger stations, reducing their operation to weekend or seasonal traffic, and opening new andpreviously closed passenger stations.
