Cyber-Physical-Social System Between a Humanoid Robot and a Virtual Human Through a Shared Platform for Adaptive Agent Ecology

Two artificial agents(a humanoid robot and a virtual human) are enriched with various similar intelligence,autonomy, functionalities and interaction modalities. The agents are integrated in the form of a cyber-physical-social system(CPSS) through a shared communication platform to create a social ecology. In the ecology, the agents collaborate(assist each other) to perform a real-world task(search for a hidden object)for the benefits of humans. A robot-virtual human bilateral trust model is derived and a real-time trust measurement method is developed. The role of taking initiative in the collaboration is switched between the agents following a finite state machine model triggered by bilateral trust, which results in a mixedinitiative collaboration. A scheme is developed to evaluate the performance of the agents in the ecology through the CPSS.The results show that the robot and the virtual human perform satisfactorily in the collaboration through the CPSS. The results thus prove the effectiveness of the real-world ecology between artificial agents of heterogeneous realities through a shared platform based on trust-triggered mixed-initiatives. The results can help develop adaptive social ecology comprising intelligent agents of heterogeneous realities to assist humans in various tasks through collaboration between the agents in the form of a CPSS.

Interactive navigation system in smart phone with vibration feedback

The traffic congestion has become an urgent problem to be solved,which appears in the domestic and foreign large and medium-sized cities.Intelligent transportation is one of the important applications of ubiquitous computing.And it＇s an important way to ease the traffic congestion of the city.Intelligent navigation system is an important embodiment of intelligent transportation.So far,there have been many kinds of traditional vehicle navigation systems.But when they are in use,drivers will pay extra attention to get the path information through the visual and auditory cues.It＇s dangerous for drivers when they drive.At the same time,with the development of science and technology,mobile navigation system has been widely used.The mobile navigation system is a comprehensive system which relates to the field of mobile communication and GPS.The objective of this paper is to develop a smart phone and interaction navigation system based on the feedback of vibration and micro programmed control unit（MCU）control system.When drivers are in the driving process,the new navigation system can avoid the same sense of multiple tasks,which makes each sensory focus on only one independent task.Through the analysis,the system is demonstrated to improve the driving safety.

Driving Smartization Through Intelligent Transport

Smart cities initiatives are developing all over the world, due to their support in favouring a better provision of services, in connection with the aim of achieving efficiency in cities management. More and more big corporations are interested in this topic to develop their businesses, as several issues are linked to these projects, like environment, water management, energy policies, education, culture, and so on. In literature these issues, known as drivers, were also related to sustainability aims which could be reached through the accomplishment of better performances within environment, economy, and society. This study synthesizes all the different drivers identified by scholars and industry players in a model, in order to use it as a framework to depict the linkages among the various smart cities projects. Since transport resulted as one of the most considered drivers in the analyzed contributions, the research questions were delineated to describe its role in the different phases of smart initiatives, and to understand if it could encourage and enable the other drivers＇ development. The multiple case study was chosen as the fittest methodological approach and it was conducted with the selection of three smart cities, one for each of the most cited platform models developed by industry players, which had started transport initiatives at least three years ago： Singapore （IBM）, Amsterdam （Accenture）, and San Francisco （Microsoft）. The analysis of the official documents set up by city departments and by the industry players showed transport as a driving force in smart cities projects which conveys a smart approach to different domains, especially energy savings, environment, and safety. The results also showed smart mobility as a pivot in stimulating investments and citizens＇ participation on different city drivers, especially as it concerns environment and services to both citizens and businesses. Smart transport initiatives, hardware and software infrastructures, technological devices, and people participation to smartization were closely interrelated in smart cities projects and they could be successfully used to achieve sustainability aims for different stakeholders.

Research on the Construction of Intelligence Community Integrated Information Service platform

With the constructions of ＂intelligence city＂, intelligent life quietly came to the people. As the ＂cell＂ of the city, the construction of intelligence community arises. Resident service system and e-government application system have been used in the traditional information community, but these systems are independent of each other, lack of interconnectedness, which results in the phenomenon of information isolated island. Intelligence community integrated information service platform can integrate information service resources and provide residents with efficient and convenient life. From the meaning, operation mode, we can design the cooperative, open and extensible system architecture.

Development of Online Based Smart House Renting Web Application

The house rental issue is one of the elemental parts of society. Nowadays, it is extremely difficult to find suitable accommodation in city areas if people search for it physically. On the other hand, the land owner also needs to rent the house. It can be difficult to find tenants just to hang a lease sign on a building, and as a result, they lose money. An online common platform can play a vital role in this case. The purpose of the study is to develop a common web-based online platform for both tenants and house owners so that both tenants and landowners will mutually benefit from the system. This paper presents the development of web applications for the people of Bangladesh where both house owners and tenants can register and tenants can have houses for rent via sophisticated contact with the house owner. In this paper, a common online-based smart house rental web application has been developed both for tenants and for house owners. This web application is very user-friendly, efficient and it has got many unique features that are not offered by other currently available house rental websites here in Bangladesh. Tenants can register using their phone number, store information about their identity, search for available houses, send messages to house owners, and choose a suitable house using developed web applications. House owners can also register for the system, which will manually verify and authenticate the knowledge provided by the house owner can view a tenant’s information history whenever a tenant makes contact through text and supply house-related information accordingly. The proposed online smart house system has been tested and validated. It works very efficiently with many features. The application provided faster and improved opportunities to get houses, as well as ensuring the availability of houses for rent in the greatest number of areas. The system will help to spread trustworthy services nationwide and supply users with the chance to speak and improve the house rent in Bangladesh. Because it has many smart features, this developed online smart house rental web application will make it very easy for tenants to find a house to rent. House owners, on the other hand, can easily rent out their properties.

中国数字平台治理的逻辑建构与路径

数字平台治理是当前社会治理的新兴领域,市场垄断、信息把关、数字伦理等是世界各国共同面临的问题。基于各自的历史脉络与制度传统,不同国家和地区形成了差异化的治理模式。总体来看,美国更强调市场竞争,欧盟则注重立法监管,英国立法与执法并重。中国的数字平台发展迅速,对应的治理模式正处于变迁、探索的过程。本文主要从智慧监管理论视角出发,分析常态化监管下中国数字平台的治理理念、治理主体与治理工具。当前,政府部门、平台企业与社会力量三方共治体系逐渐成形,立法、司法、行政力量、技术过滤等治理方式日趋灵活。
