基于同时发射声纳环移动机器人导航系统

开发了一种能在未知环境下实现快速障碍检测与障碍回避的基于同时发射声纳环移动机器人导航系统。为了消除由于同时发射造成的串话干扰,提出了一种基于神经网络模式识别的过滤方法;并制作了由24个声纳传感器组成的声纳环安装到实际的移动机器人上,实现了扫描频率最大可达到66Hz的全景检测。系统中应用了动态窗口法来完成快速障碍回避的运动规划。实际的导航实验表明,系统可用于室内未知环境中的移动机器人快速导航。

Co‐Present Conversation as “Socialized Trance”: Talk,Involvement Obligations,and Smart‐Phone Disruption

In an era where digital and co‐present involvements become entangled, the role of face‐to‐face conversation now vies with mediated communication. Applying insights provided by Erving Goffman, we explore conversational interaction and consider how engrossing face‐to‐face conversation can be understood as a form of socialized trance. We explore how this interaction represents one type of “involvement obligation” that can become disrupted and, increasingly, uniquely impacted by mediated involvements that are enabled through mobile and “smart” devices. The crux of the argument is considered in the context of a burgeoning digital era where conversation is found to become meshed together in uneven ways with mediated interaction. We highlight the efficacy of Goffman's approach with regards to the current information environment, providing insights into how engrossing conversation and its involvement obligations are impacted by mediated interactions and how breaches of conduct are experienced.

政府信息发布的时效性研究——以手机媒体为载体

《中华人民共和国政府信息公开条例》的实施要求政府向公众实行信息公开，以充分保证公众的知情权。由于现有的政府信息大都是借助于报纸、电视等传统媒介或网络媒介进行发布，加上各种因素的干扰，使得它们不能在最短的时间里被公众认知，因而对公众和政府都造成了一些不必要的损失。随着信息技术及通信技术的发展，时效性问题在信息量呈几何级数增长的今天，显得更加突出。为了使政府能够达到最有效传递信息的目的，有必要对政府信息发布的时效性进行研究。     

Locative Mobile Social Networks: Mapping Communication and Location in Urban Spaces

Abstract

This study conceptualizes the new spatial logic created by the social use of location aware mobile technologies, analyzing how mobile communities are formed by the mapping of social networks in urban spaces. It explores two main areas with the goal of understanding how locative mobile social networks (LMSNs) challenge the traditional logic of networks. First, it conceptualizes LMSNs by comparing them to (1) traditional transportation and communication networks, and (2) mobile social networks (MSNs). Second, the paper discusses potential social implications of LMSNs, such as privacy, surveillance, and social exclusion.     

The Culture of New Mobility in Russia: Networks and Flows Formation

Abstract

The paper considers the development of the culture of new mobility in Russia from the perspective of the quantitative analysis of the changes occurring in the structure of traffic movements and flows and communication using mobile phones, the internet, and other mobile gadgets. The culture of mobility is defined as a set of the interactions which are carried out apropos and during mobility. It is argued that the culture of new mobility in Russia is specified by the processes of ‘individualization’ and ‘networked individualism’. This conclusion is inferred from the rapid growth of individualized automobility, from the considerable increase in international tourism and from the widespread prevalence of mobile gadgets as indispensable attributes of everyday life.
