Social sensing belongs to an interdisciplinary research field formed in the background of Information and Communication Technology (ICT) and big data development. This can be attributed to the continuous improvements in data acquisition, processing and analysis capacity for urban and social economy studies. It has been recognized that social sensing holds potential benefits across a number of industry sectors. This chapter analyzes the influences of social sensing on Planning Support system (PSS) and decision making with specific applications in supporting data, technology, function and application aspects. A case study is provided which focuses on the renovation planning in Changxindian old town, Beijing. The case study proves that social sensing has positive effects in addressing some of the disadvantages of PSSs and enabling such systems to play a greater role in planning practice. Based on analysis, this chapter puts forward the proposition that social sensing should be adopted as a critical component of PSS for urban planning in a smart city. © Springer International Publishing AG 2017.

The paper presents an experimental study on the performance of two types of stress sensor for their possible use in structural health monitoring (SHM) of masonry constructions. Ceramic piezoelectric sensors and capacitive sensors were installed in mortar bed-joints of two series of masonry specimens made of calcarenite stones and clay bricks. The specimens were tested under uniaxial compression, assessing the effectiveness of the sensors in recording the stress state variation in terms of vertical stresses within different types of masonry. Experimental results show that, although both the ceramic and capacitive sensors were initially designed to be embedded in concrete elements, their application in mortar joints ensures a good agreement with records by standard measurement devices. Results also demonstrate the possibility to extend the application of these devices to existing masonry structures, where SHM becomes a challenging issue. © 2021, Scipedia S.L. All rights reserved.

This paper presents an integrated approach to Visual SLAM, merging online sequential photometric calibration within a Hybrid direct-indirect visual SLAM (H-SLAM). Photometric calibration helps normalize pixel intensity values under different lighting conditions, and thereby improves the direct component of our H-SLAM. A tangential benefit also results to the indirect component of H-SLAM given that the detected features are more stable across variable lighting conditions. Our proposed photometrically calibrated H-SLAM is tested on several datasets, including the TUM monoVO as well as on a dataset we created. Calibrated H-SLAM outperforms other state of the art direct, indirect, and hybrid Visual SLAM systems in all the experiments. Furthermore, in online SLAM tested at our site, it also significantly outperformed the other SLAM systems.

Docking is an important and difficult task in ship navigation that has traditionally required excessive time and expert piloting. In this study, an autonomous docking system based on symbol recognition was developed for autonomous surface vehicles (ASVs). The docking process is divided into an approaching phase for approaching the docking port and a docking phase for guiding an ASV into the target docking port. In the docking phase, the desired heading of the ASV is determined based on a combination of the centering angle and lead angle. The centering angle is used for pure tracking and the lead angle is used for guiding the ASV into the safety zone. Each angle is determined according to the relative heading angle and position of the ASV, which are estimated by detecting the dock and symbols using a camera and LiDAR. Docking tests based on Turtlebot and ASVs were conducted to verify the proposed docking algorithm. The performance of the developed autonomous docking system was verified by participating in the docking mission of the Korea Autonomous BOAT 2021. © 2022, The Authors. All rights reserved.

The efficiency of a website depends on how usable the UI user interface, (UI) is and how well it is structured. The aim of this research was to try and understand the issues with the Arion system. Arion is the student information system used by Auckland University of Technology. We conducted three experimental studies to examine the usability and to improve the user experience of student who use Arion. Three main methods were used namely; survey, open card sorting and situated co-inquiry. The survey was used to inform the study and collect more information about users. The open card sorting used to redesign the navigation menu for the system. Then the Situated co-inquiry used to discover the user's current unexpected or unforeseen ideas, which may be helpful for future research.

The product line engineering approach is a promising concept to identify and manage reuse in a structured and efficient way and is even applied for the development of safety critical embedded systems. Managing the complexity of variability and addressing functional safety at the same time is challenging and is not yet solved. Variability management is an enabler to both establish traceability and making necessary information visible for safety engineers. We identify a set of requirements for such a method and evaluate existing variability management methods. We apply the most promising method to an industrial case and study its suitability for developing safety critical product family members. This study provides positive feedback on the potential of the model-based method PLUS in supporting the development of functional safety critical embedded systems in product lines. As a result of our analysis we suggest potential improvements for it.

Software product line engineering is a widely used approach to plan and manage reuse of software. When safety critical products are developed, achieving functional safety standard compliance must be shown. The requirements stated in the functional safety standards also apply when safety critical products are developed in product lines. Managing functional safety in industrial product lines is challenging and work around solutions are applied in practice. The objective of this research is to collect and review reported research publications focusing on achieving safety in product lines and to identify gaps in todays research. We conduct a systematic mapping study of research publications reported until January 2016. We identify 39 research articles to be included in a list of primary studies and analyze how product lines are documented, which safety-related topics are covered and which evaluation method the studies apply. Generally, we find that the area of how to achieve functional safety in product lines needs more attention. Our study provides an overview on which topics have been discussed until now and which safety-related topics need more attention.

Computer Modelling and New Technologies 2014年第5期18卷 7-13页

Vibration characteristics analysis is important in the design of multi-span pipeline with different support conditions. In order to analyze the natural frequency and the vibration modal of the multi-span pipeline, a matrix transfer method is proposed in this paper. With the multi-span pipeline divided into single-span pipes, the transmission formulas for the deflection, angle, bending and shear between two adjacent spans are deduced, in combination with the Krylov function solution of the free vibration equation for the single-span pipe, and the constraint condition between the two adjacent spans of the multi-span pipeline. According to the boundary conditions on the starting and ending spans, the natural frequency equation and the vibration modal function between two adjacent spans of the multi-span pipeline are presented. The FORTRAN program based on the above principle is written, and the natural vibration frequencies and the vibration modals of two typical multi-span pipelines are investigated and compared with the results from ABAQUS. It is shown that the model presented in this paper is efficient in the analysis of multi-span pipeline and has the advantages of high computational efficiency and convenience for engineering practice application.
