“北斗”救生终端海上自适应功率退避算法

受海况、浸水、结冰、对星等因素影响，飞行员海上遇险后报位可靠性较低，工作时长较短。为此，提出一种自适应功率退避方法，在对报位影响因素分析基础上，利用深度神经网络，通过对经纬度、高度、俯仰角、方向、加速度、速度、浸水、信号、电量等多维度数据进行学习，拟合出覆冰、浪涌、液面等信号特征与环境特征联想模型，自适应控制信号发射时机，实现功耗的有效控制。试验表明，该方法将通信成功率及工作时长分别由36.3%、6.0 h提升至73.3%、8.6 h。     

融合通信系统下WiFi门禁系统的实现

传统的由计算机控制的门禁系统需要构建专用的控制网络，并且不能进行局域网之外的无线远程控制；而以IP通信为基础的融合通信，把计算机网络与传统通信网络融合为一体，将数据、音视频融合在一个网络平台上；本文实现的门禁系统，利用IP网络，将门禁和IP融合通信达成一个有机的整体，是一种能实现无线WIFI控制的门禁系统。

“合作”视角下的行政协商制度

国家治理现代化是国家治理模式变迁过程中的产物,从本质上讲,国家治理现代化是一个开放的进程,理应包含国家与社会、个人之间的"合作"。行政法理论中"交往行为"的渗透,加之"和"传统文化的传承,共同展现"合作"的现代之意。作为"合作"的实然反馈,行政协商概念的提出是对现实与文化的双重回应,而经历过功能、形式与适用范围拷问的行政协商制度,具备预防纠纷的功能,符合"合作型谈判"的形式要件,同时可在部分行政活动中针对性适用,更具建构的可行性。     

Analyzing the Memory Impact of Advertising Fragments

Marketers are making increasing use of very brief messages that mention just a brand name or a brand name with a short headline, as in event sponsorship and program endorsements. There has been debate over the effectiveness of these advertising fragments. This paper introduces an approach for controlled testing of the effects of advertising fragments. Using a reaction-time based procedure, we show that a key effect of advertising fragments is to revive established brand associations, even though these associations are not explicitly communicated. This reactivation occurs not only when these names receive focal attention, but also when they receive nonfocal attention.     

The Use of Information and Communication Technologies (ICTs) in Tourist Information and Promotion of the Polish Carpathians in Foreign Tourism Markets

The recent years have been a time of rapid development of information and communication technologies (ICTs) in tourism. The objective of this article is to analyse and assess the use of ICTs in tourist information and promotion of selected municipalities in the Polish Carpathians, the largest region of mountain tourism in Poland. Particular attention was paid to the activities taken by DMOs, local entrepreneurs and cultural institutions. The use of ICTs in the Polish Carpathians is at a relatively advanced level, but still not sufficient enough to make these solutions a fully effective tool in building a strong regional brand in the international tourism markets.     

The Relevance of Organization Theory to the Field of Business and Information Systems Engineering

Information and communication systems (ICS) impact their organizational environment in significant ways; hence, the design, implementation, and use of ICS are inseparably linked to fundamental issues of organizational design and behavior. Current research in the field of business and information systems engineering (BISE), however, is primarily technology- or practice-oriented and concerned with the construction and validation of prototypes, whereas little attention is paid to theoretical insights into organizational phenomena and relationships. In this paper, we argue that paying more attention to organization theory would provide valuable guidance in addressing the close links between ICS on the one hand, and organizational systems on the other. To support our argument, we refer to selected theoretical perspectives and highlight their potential relevance to the BISE field.

The Effects of Electronic Collaboration in Distributed Project Management

Abstact The emergence and widespread use of collaborative technologies for distributed project management has opened up opportunities for off-shore outsourcing and collaborative development. However, most tools and techniques for project management focus on on-site, long term relationships and sourcing strategies at a time when inter-organizational relationships are becoming more dynamic and geographically dispersed. This paper uses grounded theory to analyze data on virtual teams' projects. The analysis uncovers “effects” in the way in which distributed projects are managed. These effects relate to coordination, communication and adaptation to distributed electronic work environments. Following an analysis of these electronic collaboration “effects”, a model for distributed project management is presented.
