Emphasis will be on the urban fabric as in form and structure. This study will focus on both punctual (squares, crossroads and intersections) and linear (streets, alleys and cul-desacs) urban entities and their relationship with the immediate built environment. Then, we pass on to the analysis of networks of public facilities and green spaces in the Ksar. Finally, and within the same context, the housing units will be investigated in order to depict the typological constants and variables principles underpinning the spiritual content of the ksar. The outcome of this research is aimed at providing designers at different scales with the necessary understanding and knowledge to address the needs of present and future generations as well as historical, cultural, social, economic and environmental dimensions of authenticity to ensure sustainable development. 2013-12-30T00:00:00Z http://archives.univ-biskra.dz/handle/123456789/604 Titre: Démarche de caractérisation de la zone non saturée d'un site industriel. (Étude du cas de l'usine de peinture de SOUK AHRAS) Auteur(s): GHERIS, ABDERAHIM; MEKSAOUIN, MOHAMMED Résumé: Le travail abordé ici s'inscrit dans une étude globale de mise au point d'outils de caractérisation et de modélisation de flux de polluant transporté par l'eau (approche quantitative) transitant dans la zone non saturée d'un aquifère. Dans notre étude, nous présentons un modèle pratique de calcul de transfert des particules polluantes émises par une source de pollution, représentée dans notre cas par une usine de production de peintures située dans la ville de SOUK AHRAS. 2013-12-30T00:00:00Z http://archives.univ-biskra.dz/handle/123456789/603 Titre: Micro-irrigation de la tomate sous serre Auteur(s): ZELLA, LAKHDAR; SMADHI, DALILA Résumé: The agriculture in green house is one of the intensive production models, so factors of production must be maximized in order to warrant net profit. The present work consists on an example of optimal design set up of the micro-irrigation network of cultivated greenhouses of tomato. Obtained results by using a theoretical model of design showed that 157.5 litres per plantation are necessary for the irrigation during 78 h 42. One greenhouse requires 157.5 m3 and a hectare 4 000 m3. The water capacity of the network head for one hectare is 27 m3/h, if we irrigated an hectare in two times, it require 54 m3/h and 2 bars of a global pressure for the total area. From the previews observations, the equipment economic aspect of the project suggest that an amount of 13,9 millions DA per hectare and the relative expense per year is evaluated of 50 % of the global cost. 2013-12-30T00:00:00Z http://archives.univ-biskra.dz/handle/123456789/602 Titre: Images Segmentation based contour using EVCA approach, Evolutionary Cellular Automata Auteur(s): SLATNIA, S; KAZAR, O Résumé: We use an evolutionary process to seek a specialized powerful rule of Cellular Automata (CA) among a set of best rules for extracting edges in a given black-white image. This best set of local rules determines the future state of CA in an asynchronous way. The Genetic Algorithm (GA) is applied to search the best CA rules that can realize better the edge detection. 2013-12-30T00:00:00Z
