Design of Public Communication Spaces in Urban Highrises:A Case Study of Xuzhou Hanbang Square Residential Area

Highrise residences with high plot ratio meet housing needs of urban residents, improve living conditions of residents, but also show many unreasonable problems in the design of public communication spaces with a result of interpersonal indifference and lack of sense of identity. This paper took Xuzhou Hanbang Square for example to explore strategies of improving public communication spaces in highrises from the perspectives of entrance lobby, open-floor ground design, ecological garage, and three-level property management. On the one hand, the paper tries to improve quality of residential environment and service quality of public facilities; on the other hand, to enhance sense of neighborhood and identity of residents, and change the current interpersonal indifference.

Publicizing Science! To What Purpose? (Revisiting the notion of public communication of science and technology)

A [1] common lament in the realm of science and technology culture (SL and PCST [2]) is the scant regard for publicizing science and technology.Similarly decried is the chronic lack of knowledge of science and technology by a high proportion of the general public, who are said to be de facto deprived of the right to speak on issues concerning them since they cannot grasp the real impact on society of the spinoffs from science and technology development. PCST actors reiterate that the real challenge is to maintain our individual and collective capacity for intervention in a knowledge society that is ever more complex to decipher and master.……

BLE Mesh： A Practical Mesh Networking Development Framework for Public Safety Communications

Owing to advanced storage and communication capabilities today, smart devices have become the basic interface between individuals and their surrounding environment. In particular, massive devices connect to one other directly in a proximity area, thereby enabling abundant Proximity Services（Pro Se）, which can be classified into two categories： public safety communication and social discovery. However, two challenges impede the quick development and deployment of Pro Se applications. From the viewpoint of networking, no multi-hop connectivity functionality component can be directly operated on commercially off-the-shelf devices, and from the programming viewpoint, an easily reusable development framework is lacking for developers with minimal knowledge of the underlying communication technologies and connectivity. Considering these two issues, this paper makes a twofold contribution. First, a multi-hop mesh networking based on Bluetooth Low Energy（BLE） is implemented,in which a proactive routing mechanism with link-quality（i.e., received signal strength indication） assistance is designed. Second, a Pro Se development framework called BLE Mesh is designed and implemented, which can provide significant benefits for application developers, framework maintenance professionals, and end users. Rich application programming interfaces can help developers to build Pro Se apps easily and quickly. Dependency inversion principle and template method pattern allow modules in BLE Mesh to be loosely coupled and easy to maintain and update. Callback mechanism enables modules to work smoothly together and automation processes such as registration, node discovery, and messaging are employed to offer nearly zero-configuration for end users.Finally, based on the designed Pro Se development kit, a public safety communications app called Quote Send App is built to distribute emergency information in close area without Internet access. The process illustrates the easy usability of BLE Mesh to develop Pro Se apps.

How To Be A Good Speaker

Public speaking is a part of communication.Good public speaking can convey clear、 persuasive ideas or opinions and also can become an effective bridge between the audience and the speaker.This paper is dealing with some skills of public speaking- from several different aspects that should be noticed in public speaking.

Architecture and Key Technology of Distributed Intelligent Open Systems

High-speed large-bandwidth networks and growth in rich internet applications has brought unprecedented pressure to bear on telecom operators. Consequently, operators need to play to the advantages of their networks, make good use of their large customer bases, and expand their business resources in service, platform, and interface. Network and customer resources should be integrated in order to create new business ecosystems. This paper describes new threats and challenges facing telecom operators and analyzes how leading operators are handling transformation in terms of operations and business model. A new concept called distributed intelligent open system （DIOS）—a public computing communication network—is proposed. The architecture and key technologies of DIOS is discussed in detail.
