Modern science and technology is a weapon against natural disasters. Shenzhen is a city of technology and innovation and we should endeavor to address flood control, drought relief and wind mitigation (named “three-prevention” in this context). In particular, we should vigorously promote the improvement of technology, and make use of modern information technologies such as big data, internet of things, cloud computing and artificial intelligence to create intelligent three-prevention system. This paper described in detail the characteristics and the construction status of the intelligent three-prevention system as well as the future development direction, in order to achieve the construction goals of the overall situation probing of the three-prevention, real-time decision-making assistance, flat command and control and urban resilience development. Since the intelligent three-prevention system’s launch in April 2020, it has started more than 20 times of emergency response against typhoon and flood. The whole process functions of front-end intelligent perception, fine dynamic simulation, real-time forecast and early warning, emergency command and post-disaster assessment have been preliminarily realized.

Бурно развитие информационных технологий привели к широкому их внедрению во все отрасли современной науки. В работе рассмотрены вопросы использования информационных технологий для хранения и обработки информации, накапливаемых в различных геологических фондах, в частности в фондах Института геологии Дагестанского научного центра РАН. При этом основными задачами, которые необходимо решать, являются формализация и нормализация информации. Они успешно могут быть решены современными программными средствами по созданию хранилищ данных, систем их аналитической обработки, т.е. так называемых OLAP – методики и разнообразных способов интеллектуального анализа данных. Весь процесс разработки информационно-аналитической системы начинается именно с определения способов надежного хранения данных. Для этих целей использована доступная нам система управления базами данных Microsoft Access. Проведена большая работа по формализации информации по скважинам и рассмотрены проблемы разработки электронных баз данных в геологии. Используя технологию реляционных баз данных, разработана база данных гидрогеологических параметров артезианских скважин, расположенных на территории Республики Дагестан. Описана методика использования базы данных Intensive development of information technologies has led to their wide use in all spheres of modern science. This paper discusses the use of information technologies for storage and processing the information accumulated in various geological collections and, in particular, in the funds of the Institute of Geology of the Dagestan Scientific Center of Russian Academy of Sciences. The major challenge that must be addressed to is the problem of formalization and normalization of information. These problems can be successfully solved with the use of modern software tools for data warehousing, analytical data processing systems, i.e. the so-called OLAP-equipment and various means of data analysis. The whole process of development of information-analytical system begins with identifying ways of secure data storage. Thus, this article deals with the issues on creation of information-searching database of the wells drilled in different times in the territory of the Republic of Dagestan. For these purposes it is helpful to use the available database management system Microsoft Access. Quite a lot of work has been done to formalize information on wells; the problems of development of electronic databases in geology have been described. Using relational database technology developed has been the database of hydro-geological parameters of artesian wells located in the territory of the Republic of Dagestan. The technique for operation of the database is described.

Design And Manufacture

According to the development of Numerical Control (NC) machine tool’s manufacture, the way to build a platform of digitized design and manufacture system for NC machine tool was proposed, in which the various and relatively simplex digitized technologies were conformed as well as closely combined with the network and information technologies. From that, the real-time and parallel simulation in the whole process of NC machine tool’s design and manufacture would be achieved. Along with the all-sided expanding of digitized technology in the design field of NC machine tool, the corporations’ colligation which includes design, manufacture and management would be greatly upgraded and the development of entire manufacture will be expedited. And the mechanical equipments’ design and manufacture will be promoted at a larger-scale.

In recent years, the output of construction waste in China has been increasing. 70% of more than 600 large and medium-sized cities in China are surrounded by waste, of which the contribution rate of construction waste reaches 40%. Compared with some developed countries, China lacks real-time monitoring and intelligent control of the whole process of construction waste. In this paper, the popular “BIM + GIS” technology is introduced into the field of construction waste supervision. Based on this technology, a real-time monitoring and intelligent management and control information management platform for construction waste is established, so as to achieve accurate management and control of construction waste.

Knowledge of material pseudodielectric functions at MBE growth temperatures is essential for achieving in-situ, real time growth control. This allows us to accurately monitor and control thicknesses of the layers during growth. Undesired effusion cell temperature fluctuations during growth can thus be compensated for in real-time by spectroscopic ellipsometry. The accuracy in determining pseudodielectric functions is increased if one does not require applying a structure model to correct for the presence of an unknown surface layer such as a native oxide. Performing these measurements in an MBE reactor on as-grown material gives us this advantage. Thus, a simple three phase model (vacuum/thin film/substrate) can be used to obtain thin film data without uncertainties arising from a surface oxide layer of unknown composition and temperature dependence.In this study, we obtain the pseudodielectric functions of MBE-grown AlAs from growth temperature (650°C) to room temperature (30°C). The profile of the wavelength-dependent function from the ellipsometry data indicated a rough surface after growth of 0.5 μm of AlAs at a substrate temperature of 600°C, which is typical for MBE-growth of GaAs.

Abstract:On-line intelligent monitoring, diagnosis, and control of dynamic systems such as patients in intensive care units necessitates the context-dependent acquisition, processing, analysis, and interpretation of large amounts of possibly noisy and incomplete data. The dynamic nature of the process also requires a continuous evaluation and adaptation of the monitoring strategy to respond to changes both in the monitored patient and in the monitoring equipment. Moreover, real-time constraints may imply data losses, the importance of which has to be minimized. This paper presents a computer architecture designed to accomplish these tasks. Its main components are a model and a data abstraction module. The model provides the system with a monitoring context related to the patient status. The data abstraction module relies on that information to adapt the monitoring strategy and provide the model with the necessary information. This paper focuses on the data abstraction module and its interaction with the model.

The compaction quality of the subgrade is directly related to the service life of the road. Effective control of the subgrade construction process is the key to ensuring the compaction quality of the subgrade. Therefore, real-time, comprehensive, rapid and accurate prediction of construction compaction quality through informatization detection method is an important guarantee for speeding up construction progress and ensuring subgrade compaction quality. Based on the function of the system, this paper puts forward the principle of system development and the development mode used in system development, and displays the development system in real-time to achieve the whole process control of subgrade construction quality.
