Medium-term shoreline evolution of the mediterranean coast of Andalusia (SW Spain)

2015

Coastal environment is a dynamic system in which numerous natural processes are continuously actuating and interacting among them. As a result, geomorphologic, physical and biological characteristics of coastal environments are constantly changing. Such dynamic balance is nowadays seriously threatened by the strong and increasing anthropic pressure that favors erosion processes, and the associated loss of environmental, ecologic and economic aspects. Sandy beaches are the most vulnerable environments in coastal areas. The aim of this work was to reconstruct the historical evolution of the Mediterranean coastline of Andalusia, Spain. The investigated area is about 500 km in length and includ…

Klases kultūras transformācijas Latvijā fotogrāfiju un atmiņu avotos (1964–2004)

2015

„Klases kultūra” ir jauns jēdziens pedagoģijas vēstures pētniecībā. Tās elementu izpēte ar dažādu vēstures avotu palīdzību sniedz ieskatu skolas realitātē noteiktos vēstures posmos un palīdz izprast un interpretēt cilvēku individuālo pieredzi, kas saistās ar skolas dzīvi, kurā veidojas cilvēka personība, sociālie kontakti un nostiprinās garīgā un emocionālā attīstība. Raksts iepazīstina ar klases kultūras jēdziena teorētiskajiem aspektiem, kā arī, izmantojot vēstures avotu – fotogrāfiju un interviju – analīzi, tiek rekonstruēta klases kultūras tranformācija Latvijā no autoritārā režīma Padomju Savienības laikā uz demokrātisko iekārtu postpadomju Latvijā.

A Location Based Service for the production of interactive photographs

2010

Currently, photographs are an indispensable means for documenting and surveying objects and places, however, they have an inherent limitation due to a lack of identification data. Digital applications on a photograph could resolve this limitation. This paper, therefore, details the results of a research based on an innovative photographic system, with the purpose of identifying objects in digital photos. To carry out this procedure, this is achieved by partly utilizing a Location Based Service. The final product, obtained from the user in real time with a simple shot of the photo, constitutes a small information system, which enables the analysis of the images of places and objects in an in…

Evolution des paysages Sahélines au cours des six dernières décennies dans la région de Niamey : de la disparition de la brousse tigrée à l'encroutem…

2010

In the Sahel, the rapid increase of the population during the last decades and the climate variation lead to an important environmental degradation. This work aims to measure the impacts of the human pressure on ecosystem during the six last decades. A diachronic cartography of a 100 km² area close to Niamey was done with aerial photographs (1950 and 1975) and GPS measurements (2009). Results showed that the tiger bush vegetation was completely cleared between 1950 and 2009 while the fallow decreases from 7 % to 1 %. In the sandy valley, the increase of cultivated fields from 20,7 % (1950) to 69,4 % (1975) favoured wind and water erosions which allowed surface soil crusting. Between 1975 an…
