Abstract
Outdoor navigation technologies based on GPS and Beidou has been very mature. However, due to the weakness of satellite signal and refraction, they can’t satisfy the needs of indoor localization and parking area navigation in large commercial buildings. Most indoor localization technologies, such as Bluetooth and Wi-Fi, are based on active equipment. Due to the implementation cost, they can’t be widely deployed. In recent years, SLAM has been greatly developed and applied in the field of robotics and autonomous driving. For technologies such as stereo SLAM and Lidar SLAM require additional equipment, and meanwhile large scale computing will happen during point cloud matching, they are not suitable for civilian mobile usage. Considering the BIM technology, which can provide accurate 3D data of buildings, are widely used gradually, a real-time localization method combining monocular SLAM and BIM model is proposed to complete vision-based initial localization. First, we create the BIM model with the design drawings, extract the visible edge lines of model, and establish a 3D line feature database; then, intercept the key frames of the mobile camera, and extract the edge line and line feature descriptors from image, match the line features between key frames, triangulate the matched line segments, get the 3D line coordinate in first frame, mistake filter will be rolled out between multiple frames; finally, match the reconstruction result with line feature database form BIM model, register the initial position. This method can quickly and effectively perform the registration of monocular images and BIM models, get the initial position in complex spaces, and support the application scenarios such as indoor navigation, equipment maintenance, facility management, and construction monitoring.

Abstract
In view of the difficulty of sensor installation and complicated process in traditional structure health monitoring, a feature point monitoring based on optical flow is proposed in this paper. A high-speed camera is applied to capture the dynamic response of the structure under excitation, and feature point could be selected and marked at any position in the video. The movement of the selected point could be traced and calculated by feature optical flow method, and the displacement time series of the feature point could be obtained. Results show that the displacement time series obtained from proposed method in this paper is consistent with the data of the pull-wire displacement sensor, the maximum displacement error is 3.3%, the method proposed is more flexible, convenient and of low cost.

Published: May 2021

Abstract
The Whitney (2018) linear baseline correction method is used to analyze the near-fault strong motion data of the 1999 Chi-Chi earthquake and quickly calculate the co-seismic displacement. The feasibility of this method is verified by comparison with the coseismic displacement data of adjacent GPS stations. The results show that the coseismic displacement of the hanging wall is significantly larger than that of the foot wall, and largest displacements reached 707.0cm north and 369.7cm up respectively, and occurred at the hanging wall station TCU052. The results in this paper can provide references for the rapid identification of coseismic displacements using strong motion data.

Published: May 2021

Abstract
Because of good cooling, heat absorption, attenuation of heat radiation and other functions, water mist is especially suitable for ship fire extinguishing and cooling. The CFD software is used to simulate water mist fire extinguishing and cooling in a ship cabin under the condition of six different parameter combinations. When the grain size is less than 150μm, the cabin temperature can be reduced to 25°C in three minutes after water mist intervention. The larger the flow rate, the smaller the grain size, the faster the cooling rate. Fire extinguishing efficiency test of water mist in small scale ship cabin is carried out. The result shows that water mist with grain size of 100μm-150μm can quickly extinguish fire and reduce cabin temperature to 25°C in two minutes.

Abstract
With the rapid development of science and technology as well as the progress in the social economy, the urban construction has accelerated significantly, and a large number of people have poured into the city, resulting in a certain degree of deterioration of the urban environment. The concept of sustainable development put forward by the Chinese government is to use more environmentally friendly materials during construction. In this way, the material consumption and environmental pollution during construction can be reduced in order to improve the living environment of residents, and promote the efficient use of overall resources. Through the sustainable use of overall resources, it can lay a good foundation for the subsequent development and construction of cities, thereby promoting the parallelism of urban construction and environmental protection. In this case, the application of BIM technology for the design and construction of green and intelligent buildings is of great significance to the field of contemporary architecture.

Published: May 2021

Abstract
Rapid liquid printing (RLP) is a new research direction for 3D printing technology holding great promise for the field of architecture. It boasts an environmentally friendly, personalised free form mode of printing which is able to produce complex structures with ease. This paper explores recent research into the use of rapid printing technology in architecture and the bio-aesthetic value of its own properties. We have experimentally investigated the materials and techniques required for rapid liquid printing on concrete, with complicating issues pertinent to the printing system identified. A suitable digital design language was investigated following completion of the research. The combination of rapid liquid printing technology and concrete breaks away from the single research direction of 3D printing technology and moves the academic literature towards focusing on biomaterials in ecological architecture fields. Finally, we explore design systems for spaces dominated by collaboration between non-human bodies. The simulation and feedback of specific environments and the cooperation of 3D printing technology create a new and extended space of possibility between nature and architecture.

Published: May 2021

Abstract
Based on the methods of geological drilling, literature research, induction and statistics, the site investigation of an old industrial park reconstruction project in Haizhu District of Guangzhou city was completed. The landform, formation lithology, structure and hydrogeological characteristics were systematically identified. Combined with indoor test and in-situ test, the variation rules of physical and mechanical parameters of argillaceous siltstone with different weathering degrees in the site were analyzed, and the evaluation results were given. The engineering suitability and the foundation stability are evaluated. The results showed that the weathering of soft rock makes the statistical standard values of compression coefficient, compression modulus, direct fast shear cohesion and internal friction angle of rock and soil decrease. Under the saturated state, the average value of strongly weathered argillaceous siltstone is 1.51 MPa, and that of moderately weathered argillaceous siltstone is 6.2 MPa. The strength of soft rock is low after softening with water, and the differential weathering of rock mass is strong. There are great differences in rock strength, local differences between fully and strongly weathered rock surfaces, and great changes in thickness. The weathering is extremely heterogeneous, in which the influence of structure, lithology, fissures and groundwater played a key role. The foundation is generally in a stable state, and the site is suitable for the construction of the project. The research results can provide reference for similar geotechnical engineering investigation and design.

Abstract
The load-carrying properties of super-long pile were important to bridge engineering in construction and operation phases, however, the research of its load-carrying properties was imperfect. The wireless monitoring system of super-long pile foundation in bridge engineering was presented in this paper. The intelligent vibrating wire steel stress gauges were used to reflect the axial stress of pile foundation, then the sensor data was acquired using wireless intelligent acquisition instrument. The LoRaWAN was used to establish the local area network, which was long range wide area network. Thus the monitoring data of each sensor was collected by Lora modules. Furthermore, the collected data was uploaded to the cloud platform using 4G wireless communication technology. Finally, the wireless monitoring system was applied in actual bridge engineering. The results indicated that the change of monitoring data was synchronized with the progress of actual working conditions, which could reflect the dynamic process of construction to a certain extent. It could provide an important reference for similar projects in the future.

Published: May 2021

Abstract
The technological development and popularity of swarm robotics actualizes the issues of increasing the efficiency and safety of consensus achievement between the swarm elements. Currently, most studies have little or no regard for information security issues when consensus achievement among swarm elements in the presence of robots with arbitrarily malfunctioning or malicious behavior. However, in many practical applications, when exploring the external environment, a swarm of one or more malicious robots may be sufficient to allow the current consensus mechanisms to fail. One of the promising ways to ensure information security in collective decision-making is the use of blockchain technology as a distributed system designed to work in conditions of lack of trust between the parties. The use of distributed ledger technologies, due to their complexity, leads to reducing efficiency in consensus achievement. The aim of the work is to improve the safety of the process of consensus achievement in swarms of robots through the use of blockchain technology in collective design making while maintaining the effectiveness of consensus achievement between robots. Increasing the safety of decision-making by a swarm will increase the stability and the possibilities of practical application of swarm robotic systems for solving problems in aggressive environments.
