The promotion of low-carbon city tourism is an important measure to reduce carbon emissions in various regions and realize sustainability. This research explores tourists’ sensory experience the city’s economy, environment society from urban providing relevant units with a blueprint for planning. accompanies empirical cases introduces Gray Relational Analysis overcome difficulties practice, som...

This study explored the spatiotemporal characteristics of drought and ecosystem services (using soil conservation as an example) in YanHe Watershed, which is a typical water basin Loess Plateau China, experiencing erosion. Herein, was simulated using Soil Water Assessment Tool (SWAT), relationship between drought, services, meteorological, vegetation, other factors since implementation ‘Grain f...

Accurate traffic prediction is crucial to alleviating congestion in cities. Existing physical sensor-based data acquisition methods have high transmission costs, serious information redundancy, and large calculation volumes for spatiotemporal processing, thus making it difficult ensure accuracy real-time prediction. With the increasing resolution of UAV imagery, use unmanned aerial vehicles (UA...

considering the importance of quality services, the study attempted to analyze the quality of municipal services strategy in yazd. the population of this study, including all client of the area three municipality .of yazd city from this population, 111 clients were selected to answer the questionnaire. content validity of the questionnaire was confirmed by experts point of views and the reliabi...

this paper investigates the stability analysis of fuzzy relational dynamic systems. a new approach is introduced and a set of sufficient conditions is derived which sustains the unique globally asymptotically stable equilibrium point in a first-order fuzzy relational dynamic system with sumproduct fuzzy composition. this approach is also investigated for other types of fuzzy relational composit...

In this study, metal matrix hybrid composites obtained by adding B4C and graphene nanoplatelets (GNPs) powders as reinforcement elements to Al7075 were produced powder metallurgy (P/M) method. Mixture prepared supplementing with different weight ratios of (2-5-10%) GNPs (0.5%) are compressed at room temperature pressing pressures (600-700-800 MPa) then temperatures (500-550- 600C) was sintered...
