Dynamic FOV visible light communications receiver for dense optical networks

This study explores how the field-of-view (FOV) of a visible light communications (VLCs) receiver can be manipulated to realise the best signal-to-noise ratio (SNR) while supporting device mobility and optimal access point (AP) selection. The authors propose a dynamic FOV receiver that changes its aperture according to receiver velocity, location, and device orientation. The D-FOV technique is evaluated through modelling, analysis, and experimentation in an indoor environment comprised of 15 VLC APs. The proposed approach is also realised as an algorithm that is studied through analysis and simulation. The results of the study indicate the efficacy of the approach including a 3X increase in predicted SNR over static FOV approaches based on measured received signal strength in the testbed. Additionally, the collected data reveal that D-FOV increases effectiveness in the presence of noise. Finally, the study describes the tradeoffs among the number of VLC sources, FOV, user device velocity, and SNR as a performance metric.Accepted manuscrip

USING DATA MINING TO DETECT ANOMALOUS PRODUCER BEHAVIOR: AN ANALYSIS OF SOYBEAN PRODUCTION AND THE FEDERAL CROP INSURANCE PROGRAM

The analysis was conducted on the USDA's Risk Management Agency insurance data and NRCS Land Resource Regions from 1994 - 2001 to assist RMA in improving program integrity. The objective is to develop a data-mining algorithm that identifies anomalous producers and counties within LRRs based upon the percentage of acres harvested.Risk and Uncertainty,

Literature review of work based learning: October 2008

This work is the foundation for a process which will be elaborated and expanded as our knowledge and understanding of work based learning (WBL) develops. The main aim and purpose of the review is to help practitioners, policy makers and researchers to focus more effectively on relevant questions, issues or sources of evidence to inform their own research or practice in WBL in higher education. This is so that they may be able to improve the quality of the learning opportunities and processes for people already undertaking work. It scopes existing literature with a view to dissemination and reflection. The main concern of this review is work based learning where the learning outcomes are recognised through higher education awards and academic credit. The focus is on pedagogic issues relating to the provision of work-based modules and programmes, and other courses aligned to higher education awards
