A function from the domain (x-set) to the codomain (y-set) connects each x element to precisely one y element. Since each x-point originating from the domain corresponds to two y-points on the graph of a closed curve (i.e., circle, ellipse, superellipse, or ovoid) in a rectangular (Cartesian) diagram, it does not fulfil the function’s requirements. This non-function phenomenon obstructs the nonlinear regression application for fitting observed data resembling a closed curve; thus, it requires transforming the rectangular coordinate system into a polar coordinate system. This study discusses nonlinear regression to fit the circumference of a tree stem’s cross-section and its sapwood–heartwood transition by transforming rectangular coordinates (x, y) of the observed data points’ positions into polar coordinates (r, θ). Following a polar coordinate model, circular curve fitting fits a log’s cross-sectional shape and sapwood–heartwood transition. Ellipse models result in better goodness of fit than circular ones, while the rotated ellipse is the best-fit one. Deviation from the circular shape indicates environmental effects on vascular cambium differentiation. Foresters have good choices: (1) continuing using the circular model as the simplest one or (2) changing to the rotated ellipse model because it gives the best fit to estimate a tree stem’s cross-sectional shape; therefore, it is more reliable to determine basal area, tree volume, and tree trunk biomass. Computer modelling transforms the best-fit model’s formulas of the rotated ellipse using Python scripts provided by Wolfram engine libraries.

With the development of Internet of Things (IoT) and machine learning technologies, mobile geographic information systems (GISs) have developed rapidly. Moreover, mobile GIS applications serve all walks of life including remote sensing, geological disaster management, and decision support systems. This article discusses the main development methods of the Android system for mobile GIS, analyzes the characteristics of different development methods, and mainly introduces the technology of developing mobile GIS based on free and open-source software (FOSS) framework. Finally, we present a data collection framework for an Android application development, based on QGIS, QFiled, GeoServer, PostgreSQL, and GeoPackage. The mobile GIS can collect important data. Furthermore, the data collection framework uses a data aggregation technique to filter and remove redundant data. Machine learning approaches are integrated in the GIS to make it intelligent. The application, in the Xishan mining area of Taiyuan, proves that the proposed framework can complete the collection and storage of geological disaster data, which has certain practical significance. Our experimental results show that the data aggregation method is approximately 42.3–44.09 percent (training times) more efficient than the no aggregation approach. Moreover, the attention network may produce an additional overhead in the prediction process, depending on the model. This overhead is observed between 0.58% and 2.83% for the LSTM model.

En la última decada se han incrementado los robos de vehiculos en México, una de las principales causas es la falta de un sistema adecuado de seguridad que involucre la tecnología a precios razonables y pueda ofrecer una alternativa de mayor robustes en el control de apertura de la puerta o puertas del vehículo, actualmente existen sistemas que permiten el control de apertura de las puertas desde un teléfono inteligente (gama alta o con características muy específicas), pero regularmente estos sistemas están vinculados a los autos de gama alta o que ya cuentan con cierta tecnología de fábrica, pero más del 80 % de la población tiene un vehículo compacto de gama media o baja que regularmente no cuenta con esta tecnología, esta necesidad es la que detona la propuesta de diseñar un sistema con una tarjeta electrónica, sistemas de control de voltaje, motores de dc, y módulos de comunicación inalámbrica para poder tener comunicación con un teléfono inteligente convencional y mediante una interface fácil e intuitiva poder tener el control de apertura de las puertas del vehículo de gama baja.
