Web GIS-Based Temporal Analysis of Climatic Factors Impacting Heat Stroke in Karachi

引用

Journal of Geographic Information System 2024年第1期16卷 61-69页

作者： Ali atif Mahnoor Rehman Muhammad Butt Syed Mahmood Shahid Ghazi Rashid Mehmood Department of Management Victoria University Sydney Australia Department of Geography Government College University Lahore Pakistan Department of Space Science University of the Punjab Lahore Pakistan Centre of Geographic Information System University of The Punjab Lahore Pakistan

This study focuses on the impact of climate change, specifically the increasing threat of heatwaves, in Pakistan, with a particular emphasis on the city of Karachi. The Pakistan Meteorological Department (PMD) analysed a century of climatic data to reveal warming trends, attributing them to human-induced factors. The vulnerability of Pakistan to climate change is highlighted, given its warm climate and location in a region where temperature increases are expected to surpass global averages. The study examines the past three decades, noting a significant rise in the frequency of hot days, especially in Karachi, where heatwaves have become more prevalent. The aims and objectives of the study involve identifying temporal changes in temperature, rainfall, humidity, and wind speed from 1984 to 2014 in Karachi. The literature review emphasizes the health implications of heatwaves, citing increased mortality during such events globally. The study incorporates a comprehensive temporal analysis, addressing gaps in previous research by considering multiple climate indicators responsible for heatwaves. The methodology involves statistical analyses, including linear regression and Pearson correlation, applied to temperature data and urbanization parameters. Results indicate an increasing trend in heat index temperature, with heatwave vulnerability peaking in the last three decades. Heat Index Temperature Anomalies show a clear surge, emphasizing the need for new indices to control critical heat stress conditions. The study concludes that tropical climate variability, particularly heat index, is linked to extreme hot days, urging measures to reduce population vulnerability. The findings underscore the importance of policy strategies, such as integrated coastal zone management, to mitigate the adverse health effects of heatwaves in Karachi’s vulnerable population.

优先流是水通过土壤中特定路径的运动,而不是水在土壤结构里均匀地流动。由于土壤的异质性,例如裂缝、根通道或虫洞,这些优先流动路径经常形成。这种分形图案使理解和描述首选流动路线的行为变得具有挑战性。为了准确地进行水和溶质的输送,需要花费大量时间来理解和描述优先流路的增长和演变。传统模型需要改进来捕捉优先流的复杂和非线性行为。选取4块120 cm×120 cm样地,对4块样地进行染料示踪实验,以确认溶质和水的优选流动模式。数据已在Origin Lab中进行分析,以创建3D图表,并使用Sketchu p-2021 Pro向每个绘图提供0.50 L亮蓝溶液(5 g/L)。每个地块包含3个垂直的土壤剖面,每个剖面深150 cm,并且剖面墙经过广泛的刀具准备。将亮蓝留在表面24 h以渗透到土壤表面。结果表明:优先流在压实度最小且大孔隙连续性保持的区域最为突出。相反,压实的影响导致压实区域微孔隙率降低和优先流动模式减弱。亮蓝色在土壤中的最大深度可达15.5 cm。FCP的运动取决于不同的因素,如根部、毛孔、裂缝等。亮蓝色在根部可用的地方达到最大深度。在本研究中,通过使用Sketch Pro软件以三维方式显示亮蓝色运动,以便更好地理解它。此外,本研究揭示压实和随后的恢复过程如何影响土壤对水流和地表径流的敏感性。全面的3D表示,这项研究提供了对水流通道的形成和演化的深入理解。根据本研究发现的水流模式,在没有压实作用的较高位置,大孔隙连续性得以保留,择流最强。由于压实作用,微孔隙度下降,且越下侧越弱。该研究可以更好地理解水流通道的创建和演化。该研究增强对优先流及其在自然和农业生态系统中养分和水循环中的作用的了解。从这项研究中获得的见解可以为制定改进的农业用地管理策略提供信息,促进可持续和高效的水资源管理。

研究云南省陇川县脐橙园土壤与叶片养分状况，为脐橙园科学施肥提供理论依据。在脐橙园采集土壤（0～20和20～40 cm土层）和叶片样品，测定土壤和叶片养分含量，明确其丰缺状况，并计算土壤肥力综合指数。结果表明：在0～20 cm土层，土壤pH平均为5.43，31.7%的果园土壤pH在5.5～6.5，80%以上的脐橙园土壤有机质、有效磷、速效钾和微量元素含量（有效铜除外）处于适宜及以上水平，超过60%的土壤交换性钙、镁和有效铜含量处于缺乏水平；在20～40 cm土层，土壤pH变幅在4.22～7.49，91.4%的土壤有机质含量>15 g·kg-1，交换性钙、镁和有效铜含量低，其他养分处于适宜及以上水平。0～20 cm土层土壤pH、速效钾、交换性镁和微量元素（有效铁除外）含量显著高于20～40 cm，其他指标在两个土层间无显著差异。叶片磷、钾、钙和微量元素含量处于适宜及以上水平，49.3%的叶片氮含量和87.3%的镁含量处于较低水平。0～20和20～40 cm土层土壤综合肥力指数分别为0.57和0.46，均为中等水平。综上，陇川县脐橙园土壤pH较低，土壤交换性钙、镁及有效铜含量缺乏，其他养分适宜，叶片氮和镁含量严重不足，其他营养元素含量为适量及以上水平。因此，在生产中应适当施用石灰或碱性肥料调节土壤pH，土施或叶片喷施钙肥、镁肥和铜肥，提高脐橙园土壤和叶片营养水平，促进脐橙的提质增效。

Multiple Deep-Belief-Network-Based Spectral-Spatial Classification of Hyperspectral Images

引用

Tsinghua Science and Technology 2019年第2期24卷 183-194页

作者： atif Mughees Linmi Tao Pervasive Computing Division Tsinghua National Laboratory for Information Science and Technology Department of Computer Science and Technology Tsinghua University

A deep-learning-based feature extraction has recently been proposed for HyperSpectral Images(HSI)classification. A Deep Belief Network(DBN), as part of deep learning, has been used in HSI classification for deep and abstract feature extraction. However, DBN has to simultaneously deal with hundreds of features from the HSI hyper-cube, which results into complexity and leads to limited feature abstraction and performance in the presence of limited training data. Moreover, a dimensional-reduction-based solution to this issue results in the loss of valuable spectral information, thereby affecting classification performance. To address the issue, this paper presents a Spectral-Adaptive Segmented DBN(SAS-DBN) for spectral-spatial HSI classification that exploits the deep abstract features by segmenting the original spectral bands into small sets/groups of related spectral bands and processing each group separately by using local DBNs. Furthermore, spatial features are also incorporated by first applying hyper-segmentation on the HSI. These results improved data abstraction with reduced complexity and enhanced the performance of HSI classification. Local application of DBN-based feature extraction to each group of bands reduces the computational complexity and results in better feature extraction improving classification accuracy. In general, exploiting spectral features effectively through a segmented-DBN process and spatial features through hyper-segmentation and integration of spectral and spatial features for HSI classification has a major effect on the performance of HSI classification. Experimental evaluation of the proposed technique on well-known HSI standard data sets with different contexts and resolutions establishes the efficacy of the proposed techniques,wherein the results are comparable to several recently proposed HSI classification techniques.

Directional mechanical and thermal properties of single-layer black phosphorus by classical molecular dynamics

Chinese Physics B 2018年第1期27卷 535-540页

作者： Afira Maryam Ghulam Abbas Muhammad Rashid atif Sattar Department of Physics Riphah International University Department of Nanoscience and Nanotechnology Research Institute of Physics and Chemistry Chonbuk National University Department of Physics COMSATS Institute of Information Technology Department of Physics Simulation Laboratory The Islamia University of Bahawalpur

Black phosphorus （BP） has received attention due to its own higher carrier mobility and layer dependent electronic properties, such as direct band gap. Interestingly, the single layer black phosphorus （SLBP） has had large popularity in applications related to thermoelectric, optoelectronic, and electronic devices. Here, we investigate the phonon spectrum, thermal conductivities, and stress strain effects. Robust anisotropy was mainly observed in the thermal conductivities together with the alongside zigzag （ZZ） direction value, compared to the armchair （AC） directions. We also investigated the attitude of stress that was anisotropic in both directions, and the stress effects were two times greater across the ZZ path than those in the AC direction at a low temperature. We obtained a ~oung＇s modulus of 63.77 and 20.74 GPa in the AC and ZZ directions, respectively, for a strain range of 0.01. These results had good agreement with first principle calculations. Our study here is useful and significant for the thermal tuning of phosphorus-based nanoelectronics and thermalelectric applications of phosphorus.
