    Équité environnementale et accessibilité aux parcs à Ho Chi Minh Ville (Vietnam)

    Anh Tu Hoang1 , Philippe Apparicio1, Thi-Thanh-Hien Pham2

    Revue Internationale de Géomatique, Vol.29, No.2, pp. 135-158, 2019, DOI:10.3166/rig.2019.00071

    Abstract The objective of this article is to assess environmental equity regarding the accessibility of parks for four population groups (children, older people, low-education individuals, and highly-educated persons) in Ho Chi Minh City (HCMC). To achieve this, two accessibility measures calculated according to network distance in GIS: the distance to the nearest park (immediate proximity) and the enhanced two-step floating catchment area method (availability based on supply and demand). Several regression models were then constructed, with the accessibility measures as dependent variables and the percentages of the four groups as independent variables. The results show that the accessibility of parks in… More >

    L’évolution de l’occupation du sol et des inégalités environnementales dans la ville minière de Métlaoui par le biais d’un SIG-AMC

    Bilel Salhi1 , Mohsen Dhieb2,3, Yamna Djellouli4

    Revue Internationale de Géomatique, Vol.29, No.3, pp. 381-399, 2019, DOI:10.3166/rig.2020.00094

    Abstract The city of Métlaoui is the most important urban core in Gafsa Mining Basin (BMG) in southwestern Tunisia. Like other BMG cities, it is characterized by a single industrial activity of phosphate enrichment and observes a spatial activity between the “European village” favorized to a certain term and the peripheral cities disadvantaged. Today, this dichotomy is not decreasing; on the contrary, the research reveals real signs of accentuation of this socio- spatial segregation inherited from colonial and post-colonial periods, and the environmental vicissitudes confirm the territorial iniquity. The research methodology has used for the social-spatial aspect heterogeneous data sources and… More >

    Transcriptome analysis reveals tumor antigen and immune subtypes of melanoma


    Oncology Research, Vol.31, No.3, pp. 389-403, 2023, DOI:10.32604/or.2023.029274

    Abstract Purpose: To screen potential tumor antigens for melanoma vaccine development and identify different immune subtypes. Methods: Transcriptional data (HTSEQ-FPKM) and clinical information of a 472 Melanoma cohort GDC TCGA Melanoma (SKCM) were downloaded from the UCSC XENA website (). Subsequently, transcriptome data and clinical information of 210 melanoma cohort GSE65904 were downloaded from Gene Expression Omnibus (GEO), a large global public database. All the transcriptome expression data matrices were log2 transformed for subsequent analysis. GEPIA, TIMER, and IMMPORT databases are also used for analysis. Cell function experiments were performed to validate the role of the IDO1 gene in melanoma cell… More >

    Vers une approche psychoacoustique et qualitative des paysages sonores de la commune de Sidi Bou Saïd

    Mohamed Amin Hammami1 , Christophe Claramunt2

    Revue Internationale de Géomatique, Vol.30, No.2, pp. 215-243, 2020, DOI:10.3166/rig.2022.00113

    Abstract The research presented in this paper introduces a qualitative approach for the representation of urban sound scapes. The approach combines a series of in situ psychoacoustics measurements recorded with different sensors with a qualitative evaluation derived from human beings acting in these urban environments. The experiments realized in the city of Sidi Bou Saïd illustrate the potential of the combination of the quantitative and qualitative views, as well as demonstration of the feasibility of the whole approach when experimented in a real urban environment.

    Vers une mesure des « vides alimentaires dans un contexte urbain hétérogène

    Réflexion méthodologique et application à Lyon-Saint-Étienne

    Luc Merchez1 , Hélène Mathian2 , Julie Le Gall3

    Revue Internationale de Géomatique, Vol.30, No.1, pp. 85-104, 2020, DOI:10.3166/rig.2020.00103

    Abstract The issue of food and characterization of food environments has been the subject of many studies and methodological developments to report and account for accessibility differentials. In the United States most studies are interested in this question with regard to health issues and have led to identify “food deserts”. As part of a project for which the main goal is to explore the transferability of this notion to other spaces, with a broader perspective on spatial justice, we propose a generic framework to shed light on this highly spatial question, generally addressed by qualitative (surveys, interviews) or quantitative methods (GIS-based… More >

    Articuler cognition spatiale et cognition environnementale pour saisir les représentations socio-cognitives de l’espace

    Thierry Ramadier

    Revue Internationale de Géomatique, Vol.30, No.1, pp. 13-35, 2020, DOI:10.3166/rig.2020.00101

    Abstract This article is based on a body of research on spatial cognition in order to show, on the one hand, that still scattered results argue in favour of a social construction of “mental maps”, and on the other hand, that it is by combining the analysis of the social meanings of geographical space (environmental cognition) with that of the topological distributions of geographical elements internalised by individuals (spatial cognition) that it is possible to account for this socialisation of cognitive mapping. The author thus questions the reasons that hinder a socio-cognitive analysis of “mental maps”, whereas, moreover, cartographic representations are… More >

    Une ontologie orientée objet pour la modélisation des socio-écosystèmes

    Éric Masson

    Revue Internationale de Géomatique, Vol.31, No.1, pp. 199-230, 2022, DOI:10.3166/RIG.31.199-230

    Abstract This article is a positional paper and an ontological contribution to the modelling of socio-ecosystems (SES). It is also an epistemic position that is anchored on the objectoriented approach. We thus propose a model of knowledge organisation that allows more complexity to be integrated into the multidisciplinary deconstruction and analysis of SES. This object-oriented ontological proposal is based on six concepts of high abstraction level allowing a transdisciplinary portability around the structures, functions, connections, phases, scales and adaptations of SES. After defining our position on object-oriented spatiotemporal modelling, we present the six concepts and explain the interest of a top… More >

    Assessment of Aged Offshore Jacket Type Platforms Considering Environmental Loads and Degradation Parameters

    Yazeed Al-Radhi1,*, Farzad Hejazi2, Azmi Abdulkarim3, Ali Feroozi4

    Structural Durability & Health Monitoring, Vol.17, No.2, pp. 89-113, 2023, DOI:10.32604/sdhm.2023.011439

    Abstract Offshore steel structures are a common investment in oil and gas industries operating in shallow to medium depth seas. These structures have become increasingly popular since the mid-19th century, with a typical design life of 30-50 years. Despite their popularity, the structural integrity of existing offshore structures remains a controversial topic. Environmental loads and material degradation have been identified as significant factors that can compromise the structural integrity of offshore structures. To address this issue, this study aims to investigate the reserved strength capacity of a selected offshore structure located in the Malaysian Seas. The study will explore the effect… More >

    An Investigation of Battery Energy Storage Aided Wind-Coal Integrated Energy System

    Enhui Sun1,2, Jiahao Shi1,2, Lei Zhang1,2,*, Hongfu Ji1,2, Qian Zhang1,2, Yongyi Li1,2

    Energy Engineering, Vol.120, No.7, pp. 1583-1602, 2023, DOI:10.32604/ee.2023.027790

    Abstract This paper studies the feasibility of a supply-side wind-coal integrated energy system. Based on grid-side data, the load regulation model of coal-fired power and the wind-coal integrated energy system model are established. According to the simulation results, the reasons why the wind-coal combined power supply is difficult to meet the grid-side demand are revealed through scenario analysis. Based on the wind-coal combined operation, a wind-coal-storage integrated energy system was proposed by adding lithium-iron phosphate battery energy storage system (LIPBESS) to adjust the load of the system. According to the four load adjustment scenarios of grid-side instructions of the wind-coal system,… More >

    Data Layout and Scheduling Tasks in a Meteorological Cloud Environment

    Kunfu Wang, Yongsheng Hao, Jie Cao*

    Intelligent Automation & Soft Computing, Vol.37, No.1, pp. 1033-1052, 2023, DOI:10.32604/iasc.2023.038036

    Abstract Meteorological model tasks require considerable meteorological basis data to support their execution. However, if the task and the meteorological datasets are located on different clouds, that enhances the cost, execution time, and energy consumption of execution meteorological tasks. Therefore, the data layout and task scheduling may work together in the meteorological cloud to avoid being in various locations. To the best of our knowledge, this is the first paper that tries to schedule meteorological tasks with the help of the meteorological data set layout. First, we use the FP-Growth-M (frequent-pattern growth for meteorological model datasets) method to mine the relationship… More >
