Abstract

The article substantiates the necessity of forming environmental culture in the field of water consumption using software products. The paper creates a concept of a smart information system that combines a mobile application and technical devices that provide real-time control of water consumption and the occurrence of abnormal or emergency situations that significantly increase water consumption. Algorithms realizing the functional capabilities allow collecting and processing data from these devices and promptly recommend effective control actions. In addition, an interactive game is available to the user, which implies periodic performance of tasks related to household environmental literacy. Using object-oriented design methods, a user graphical interface has been created and a fragment of such a game is presented in the paper.

Abstract

Object segmentation and object tracking are fundamental research area in the computer vision community. These two topics are diffcult to handle some common challenges, such as occlusion, deformation, motion blur, and scale variation. The former contains heterogeneous object, interacting object, edge ambiguity, and shape complexity. And the latter suffers from difficulties in handling fast motion, out-of-view, and real-time processing. Combining the two problems of video object segmentation and tracking (VOST) can overcome their respective difficulties and improve their performance. VOST can be widely applied to many practical applications such as video summarization, high definition video compression, human computer interaction, and autonomous vehicles. This article aims to provide a comprehensive review of the state-of-the-art tracking methods, and classify these methods into different categories, and identify new trends. First, we provide a hierarchical categorization existing approaches, including unsupervised VOS, semi-supervised VOS, interactive VOS, weakly supervised VOS, and segmentation-based tracking methods. Second, we provide a detailed discussion and overview of the technical characteristics of the different methods. Third, we summarize the characteristics of the related video dataset, and provide a variety of evaluation metrics. Finally, we point out a set of interesting future works and draw our own conclusions.

Abstract

A novel coordination polymer, [Pb(L)(1,3-bdc)]·2H2O (1), (L = 2-(2,6-dichlorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline, 1,3-H2bdc = 1,3-benzenedicarboxylic acid) has been successfully prepared under hydrothermal conditions. The structure of 1 is a 1D chain structure, which further stacks together to form a 3D supramolecular architecture by π–π interactions and C–H⋯π interactions. In addition, the thermogravimetric analysis of 1 has been investigated.

Abstract

Background Mycoplasma pneumoniae pneumonia (MPP) can cause a variety of intrapulmonary and extrapulmonary injuries, including thrombotic diseases, which seriously endanger the health of children. And for assessing the coagulation status, routine coagulation parameters has great limitations, while thromboelastography (TEG) can be comprehensively and rapidly, but there are few data on TEG used in condition evaluation in children with MPP. Objective To explore the value of TEG in condition assessment of children with MPP. Methods Two hundred and twelve MPP children were recruited from the Affiliated Changzhou No.2 People's Hospital of Nanjing Medical University from July 2019 to July 2021, including 52 with severe condition and 160 with non-severe condition. Comparisons were made between two groups in terms of demographics, platelet count, routine coagulation parameters, and TEG parameters. The association of TEG parameters with platelet count and routine coagulation parameters was assessed. Multivariate Logistic regression analysis was used to explore influence factors for the condition of MPP. ROC analysis was used for assess the value of those identified risk factors for predicting the condition of MPP. Results Both groups had no significant differences in sex ratio and mean age (P>0.05) . Compared with children with non-severe condition, those with severe conditionhad shortened reaction time (R) and kinetic time (K) , and elevated maximum amplitude (MA) , α-angle, clotting index (CI) , fibrinogen (FIB) , prothrombin time (PT) , international normalized ratio (INR) , D-dimer (D-D) (P
