This paper assesses the effects of prolonged exposure of RFID to water on the performance of existing TAG recognition systems. The dataset used in this research is collected using a high-end, multispectral RFID scanner. To perform a data acquisition, we recruited volunteers to contribute their fingerprint samples to the dataset in multiple sessions. Once the dataset is filled with both fingerprints under normal and wrinkled conditions, we use a minutiae-based fingerprint verification system to retrieve the match scores between all combinations of prints. Finally, we use receiver operating characteristic (ROC) curve to measure the behavior of such systems under maritime environment. Using the equal error rate (EER), we successfully quantify the degradation in performance due to water-induced skin pruning, which is approximately 1% reduction in EER. Emphasis on energy efficiency has led the energy regulatory organizations and utilities to sponsor the study and development of alternative and improved designs for the efficient delivery of hot water in the home. The Alliance for Water Efficiency has gathered a wide variety of documents relevant to the topic of hot water distribution and use, many of them originating from hot water distribution expert, Gary Klein formerly of the California Energy Commission. A hot water heater sensor can be configured to determine a level of hot water available for resident use. A set of facets can control a distribution of hot water within a residence. Communication transceivers can be communicatively linked to the hot water heater and the facets to exchange digital information regarding hot water availability and consumption to a home-automation communication hub. A user device with a graphical user interface can present information derived from the hot water heater sensor and the facets to control, monitor, regulate, or change hot water availability to resident members via the graphical user interface.
