基于超声波雷达传感器的AGV导航参数选择

针对自主导引车(AGV)的已有导引方式灵活性差和精度低等问题,提出使用超声波雷达传感器实现AGV自主导航并设置合理的导航模型参数。分别建立AGV的运动学模型和传感器的观测模型,为了表征实际的系统误差,基于一致性检测原理为过程模型和观测模型添加乘性或加性噪声。仿真结果表明:设置适当的噪声参数大小,可以实现AGV沿基准路线的自主导航运动。

Optimal linear filter design for systems with correlation in the measurement matrices and noises: recursive algorithm and applications

This paper addresses the optimal least-squares linear estimation problem for a class of discrete-time stochastic systems with random parameter matrices and correlated additive noises. The system presents the following main features: (1) one-step correlated and cross-correlated random parameter matrices in the observation equation are assumed; (2) the process and measurement noises are one-step autocorrelated and two-step cross-correlated. Using an innovation approach and these correlation assumptions, a recursive algorithm with a simple computational procedure is derived for the optimal linear filter. As a significant application of the proposed results, the optimal recursive filtering problem in multi-sensor systems with missing measurements and random delays can be addressed. Numerical simulation examples are used to demonstrate the feasibility of the proposed filtering algorithm, which is also compared with other filters that have been proposed.     

Attitudes towards mobile banking: are there any differences between users and non-users?

Extant research has focused on monitoring the behaviour of people who use mobile banking (MB) but it has paid little attention to understanding the impact of information technology usage behaviour due to cultural differences. Humans are the weakest link in information technology adoption; past research has shown that not all users are predisposed to change their behaviour radically and adopt new channels of banking. This paper examines the demographic patterns of users and non-users of MB. The paper also investigates the attitudinal influences of users and non-users of MB based on innovation attributes. Using empirical research, the study identifies constructs of innovation attributes that were perceived to be significantly different among the users and non-users of MB. The study provides valuable insights into MB in Saudi Arabia that have not been previously investigated. From a practical point, findings of this study will be particularly useful to banks, financial institutions and telecommunication service providers.

以抚仙湖流域为研究区域,通过系统收集分析流域多年水量水质监测数据,诊断流域保护与发展面临的主要矛盾,并基于流域一体化管理思想,提出了流域保护与发展的可能路径:1创新抚仙湖流域生态文明示范区行政管理体制,从发展思路确立抚仙湖流域实施"严格环境保护、创新生态发展"的转型战略,真正树立和实现"大景区"环境保护和"大旅游"产业发展的生态文明建设理念;2在全面实现生态发展战略的前提下,建议将流域实施分区管控,调减农业用地面积,积极发展现代观光农业和旅游业;3通过生态搬迁,优化城乡布局,实施抚仙湖流域全域"大旅游景区"战略,实现生态资源-资产-资本的良性转化。     

Expectations and Experiences With MyLabourParty: From Right to Know to Right to Participate?

Social media are often argued to change political communication, decreasing the distance between politicians and citizens, and increasing citizens' influence on policymaking. This paper presents findings from a study of how the Norwegian Labour Party uses social media, focusing on the community platform MyLabourParty. Interviews with politicians and a survey with citizens as respondents were conducted to examine the experiences of online political discussions. Findings show that citizens and politicians expect MyLabourParty to strengthen citizen participation. Yet, citizens still experience communication asymmetry and politicians may find it challenging to participate to the extent citizens expect. Means for bridging the gap between expectations and experiences are called for, in particular redefinition of the offering, changes of user‐practices, and system improvements.
