The growing popularity of Free and Open Source (FOSS) GIS software is -without doubtsdue to the possibility to build and customize geospatial applications to meet specific requirements for any users. From this point of view, QGIS is one of the most flexible as well as fashionable GIS software environment which enables users to develop powerful geospatial applications using Python. Exploiting th...

ESD phenomenon has become a serious problem for IC products fabricated by deep-submicron CMOS technologies. To qualify the ESD immunity of IC products, there are some test methods and standards developed by some organizations, which are ESDA, AEC, EIA/JEDEC, and MIL-STD organizations. ESD events have been classified into 4 models, which are HBM, MM, CDM, and SDM. Besides, there are 4 modes of p...

Analyzing real-world events captured in video is often a very time-consuming and labor-intensive process. This paper describes Video Assist, a software tool designed to assist encoding arld analyzing actions recorded on video tape. It presents the design rationales underlying its features such as: customizable objects and their attributes, their integration with an outliner and timeline diagram...

Abstract Under the “ultra-conventional” control measures of COVID-19 period, urban population distribution is different from usual time. Studying its evolution laws has a certain reference effect for judgment aggregations, division precise zoning, and differentiated management places during period. Based on data Baidu heat maps points interest (POIs), this paper uses three models density index ...

A Geographical Information System (GIS) provides a powerful collection of tools for the management and visualization of spatial data. These tools can be even more powerful when they are integrated with methods for spatial data analysis. In this context, we provide several examples that show the power of exploratory spatial data analysis (ESDA) within a GIS and how this can provide the foundatio...

This paper aimed to identify the main factors that influence homicides in state of Alagoas, Brazil. Therefore, we employed Exploratory Spatial Data Analysis (ESDA) technique and estimated spatial models order fix autocorrelation. Although several articles have explored this theme for other states Brazil, chose a small northeastern since it lead homicide ranking per 100 thousand inhabitants 2010...

In order to promote the sustainable development of sports facilities, statistical data football fields in 13 districts Wuhan city were selected. Based on geographic information system (GIS) and exploratory spatial analysis (ESDA) technology, this paper analyzed global local autocorrelation number per capita city. The results indicate that: (1) Comparing new Wuhan, central was relatively few. (2...

The spatial distribution pattern of cultural resource generally manifests clustered qualification to some extent, and we can infer the vicissitudes of the correlative culture by analyzing the changing rule of the spatial distribution pattern of cultural resource. However, the majority of the concerned researches are still at the level of qualitative statistics and thematic map visualization of ...
