Summary: Conventional building energy analysis methods often overlook the spatial and temporal heterogeneity of energy consumption. This study proposes a geographically and temporally weighted regression (GTWR) model to improve the accuracy and reliability of building energy modeling. The results show that the GTWR model outperforms other models in terms of goodness-of-fit and average absolute error. The number of floors and energy stars are identified as the most significant factors in evaluating site energy use intensity (EUI).

Summary: This study demonstrates the use of remote sensing and Geographic Information System (GIS) to extract land surface temperature (LST) from the Landsat datasets. The research focuses on the lower catchment area of the Kharun river in Chhattisgarh, India, and examines how land use has changed over time and its impact on LST. The findings reveal an increase in LST due to urbanization, with urban areas experiencing higher temperatures compared to forest and water cover.

Summary: A groundwater quality map was created and evaluated to assess the quality and changes in groundwater in Erbil, Iraq. The water quality index (WQI) was calculated based on 13 parameters, showing a decrease in water quality in 2017 compared to previous years. Untreated domestic and industrial wastewater were identified as the main cause of groundwater pollution in the city.

Summary: This paper proposes a model of contributor's reputation based on the semantic similarity of ontology concepts, which calculates the contributor's evaluation reputation by synthesizing the semantic similarity, geometric similarity, and topological similarity of object versions. The experimental results show that the proposed model can eliminate evaluation bias caused by semantic changes between versions and the obtained user's reputation is positively correlated with data quality.

Summary: In this paper, a spatio-temporal joint-modeling tracker named STTrack is proposed for continuous object tracking in video sequences. The proposed method concentrates on the temporal connection of the object by employing a time-sequence iteration strategy (TSIS) and captures the spatio-temporal correlation of the object between frames using a novel spatial temporal interaction Transformer network (STIN). Experimental results demonstrate that STTrack achieves excellent performance on six tracking benchmark datasets while operating in real-time.

Summary: Urbanization is the main driver of global environmental and land use land cover changes. This study used Geographic Information System to analyze the changes in land use and land cover in Peshawar district and linked the results with environmental aspects and DPSIR framework. The results showed a significant increase in vegetation cover due to government afforestation projects, but also a major expansion in built-up areas. The adverse effects of urbanization on the natural environment should be addressed by the government and environmental protection agencies.

Summary: The aim of this study was to optimize the parameters of a support vector regression (SVR) model for spatio-temporal modeling of asthma-prone areas in Tehran, Iran using genetic algorithm (GA) and teaching-learning-based optimization (TLBO) algorithm. The results showed that the SVR-GA and SVR-TLBO models had higher accuracy than the SVR model in predicting asthma occurrence in different seasons.
