针对传统方法在5G共享输电杆塔倾斜监测应用中存在较大的监测误差,提出了多传感器的5G共享输电杆塔倾斜监测方法.以双轴倾角传感器和加速度传感为测量仪器,采集了5G共享输电杆塔姿态数据,利用Kalman滤波技术,对5G共享输电杆塔倾角数据和加速度数据进行滤波,利用建立的坐标系分析滤波后的数据,计算5G共享输电杆塔倾斜变化情况,以完成多传感器的5G共享输电杆塔倾斜监测.经实验证明,此次监测结果误差小于传统方法,可以准确地监测5G共享输电杆塔倾斜情况. 相似文献

The changing and challenging conditions of the 21st century have been significantly impacting our economy, society and built and natural environments. Today generation of knowledge, mostly in the form of science, technology, engineering, mathematics, and arts, is seen as a panacea for the adaptation to changes and management of challenges. Making space and place that concentrate on knowledge generation, exchange, and marketing has become a priority for many nations. Consequently, the concept of knowledge city is coined at the beginning of the century and since then it is widely researched and practiced. This paper aims to scrutinise and provide a clear understanding on the evolution of knowledge city research and practice. As the methodological approach, the study employs systematic review of the knowledge city empirical studies in peer-reviewed journals. The findings shed light on the emerging patterns, identify research and practice gaps, and point out research directions to advance the field. 相似文献

We study Spanish savings banks from the point of view of their efficiency, transparency in the disclosure of financial information through the net, and the provision of electronic banking services. Performance indicators are developed using data envelopment analysis and the tools of multivariate statistical analysis. The choice of indicators is framed within the theory of intangible assets. An attempt is made rank savings banks according to their level of achievement in each indicator. Savings banks are shown to be classified into four groups according to the level of achievement in the indicators of transparency and e-service. The relationship between efficiency and profitability is also discussed. 相似文献

This paper addresses the critical role leadership plays in the implementation and facilitation of knowledge management activities. Leadership is particularly important for organizations willing to ‘evolve’ their culture to a knowledge-supporting culture. Organizational culture has been identified as the main impediment to knowledge activities, and therefore leaders should model the proper behaviors causing culture to evolve in a way that enables and motivates knowledge workers to create, codify, transfer, and use and leverage knowledge. In the literature this leadership behavior is referred to as ‘leading through a knowledge lens’. Leading through a knowledge lens has some special characteristics since it is dealing with knowledge workers having specialized expertise. Leading them can be done only by intellectual power, conviction, persuasion, and interactive dialog. It requires skills that build confidence and engagement. Therefore, leaders should establish trust and commitment that will help the knowledge organization to achieve its knowledge and business goals. 相似文献

This paper presents a conceptual model to explore the knowledge integration (KI) practices of internal and external company actors involved in the New Product Development (NPD) process of the aerospace industry. The model is based on the linkage of elasticity principles, particularly Hooke’s Law, to Knowledge Management theory. KI practices are considered as a force pushing the NPD process and are metaphorically described as the spring addressed by Hooke’s law. The integration of the knowledge of internal and external company actors impacts NPD, reducing the dimensions of the whole process, in terms of phases, through the application of the concurrent engineering approach. The whole NPD process is improved in terms of the reduction of uncertainty and complexity, and with an ‘integrated energy’ that sustains the pressure of the fast-changing competitive environment. The model is explored to provide an interpretation of the conceptualisation phase of a new aerospace product development process. Qualitative data were collected and analysed. Insights regarding the applications of the model and the theoretical implications are also provided for applications in other industries. 相似文献

This paper argues that the traditional employment relationship based on long-term commitment and reciprocity has been replaced by one which incorporates a high level of precariousness and that individuals form perceptions of the trust they have in the organisation based on their view of the psychological contract. This paper develops a model of these perceptions and develops six propositions about an individual's level of trust in the organisation, management and fellow workers and their belief that their expectations will be progressively met and that they will be compensated in the long term for their contribution. These perceptions and the six propositions developed in the paper have profound ramifications for the willingness of individuals to converse and potentially to share their knowledge with others for the benefit of the organisation, because high levels of trust will be needed before individuals will be predisposed to start to converse and exhibit a willingness to share their knowledge. 相似文献

This paper reports the findings from a survey conducted in Australia to explore current practices relating to knowledge management (KM) and intellectual capital (IC). A systematic approach in the form of the intellectual capital web guided the research. Findings revealed that KM was perceived to be more about developing knowledge culture than about managing organisational processes and structure. IC was perceived to be more about human capital than about customer capital and organisational capital. It can therefore be concluded that human capital holds the greatest importance for KM and IC. However, when facilitators for knowledge creation and knowledge sharing were rated, organisation structure was perceived to be more important than organisational culture and information technology. For KM practices, participants indicated that more attention was paid to training and developing employees and less to measurement and reward and incentive issues. The importance of aligning the management of IC and KM was perceived to be more important than the difficulty of doing so. 相似文献

Based on an exploratory study of the work and learning processes of highly skilled and experienced knowledge workers, this paper explores an alternative perspective to knowledge management, one that focuses on how individual workers apply knowledge processes to support their day-to-day work activities – broadly characterized as problem solving – and learning practices. Developing the concept of Personal Knowledge Management, the paper presents an emergent model that links distinctive types of problem solving activities with specific cognitive, information, social and learning competencies, supported by an individual, social and organizational enablers. 相似文献

Looking to the Internet for models of governance 总被引:3,自引:0,他引:3
If code is law then standards bodies are governments. This flawed but powerful metaphor suggests the need to examine more closely those standards bodies that are defining standards for the Internet. In this paper we examine the International Telecommunications Union, the Institute for Electrical and Electronics Engineers Standards Association, the Internet Engineering Task Force, and the World Wide Web Consortium. We compare the organizations on the basis of participation, transparency, authority, openness, security and interoperability. We conclude that the IETF and the W3C are becoming increasingly similar. We also conclude that the classical distinction between standards and implementations is decreasingly useful as standards are embodies in code – itself a form of speech or documentation. Recent Internet standards bodies have flourished in part by discarding or modifying the implementation/standards distinction. We illustrate that no single model is superior on all dimensions. The IETF is not effectively scaling, struggling with its explosive growth with the creation of thousands of working groups. The IETF coordinating body, the Internet Society, addressed growth by reorganization that removed democratic oversight. The W3C, initially the most closed, is becoming responsive to criticism and now includes open code participants. The IEEE SA and ITU have institutional controls appropriate for hardware but too constraining for code. Each organization has much to learn from the others. 相似文献
