PresenceSense: Zero-training Algorithm for Individual Presence Detection based on Power Monitoring

Non-intrusive presence detection of individuals in commercial buildings is much easier to implement than intrusive methods such as passive infrared, acoustic sensors, and camera. Individual power consumption, while providing useful feedback and motivation for energy saving, can be used as a valuable source for presence detection. We conduct pilot experiments in an office setting to collect individual presence data by ultrasonic sensors, acceleration sensors, and WiFi access points, in addition to the individual power monitoring data. PresenceSense (PS), a semi-supervised learning algorithm based on power measurement that trains itself with only unlabeled data, is proposed, analyzed and evaluated in the study. Without any labeling efforts, which are usually tedious and time consuming, PresenceSense outperforms popular models whose parameters are optimized over a large training set. The results are interpreted and potential applications of PresenceSense on other data sources are discussed. The significance of this study attaches to space security, occupancy behavior modeling, and energy saving of plug loads.Comment: BuildSys 201

Information System for NGO Libraries in Pakistan: A Proposed Model for Organizing the Grey Literature by Syed Attaullah Shah and Humera Ilhaq

Abstract In recent years, especially in developed countries, various systems have been created to advance the management and organization of grey literature. Such systems use the latest communication technology and electronic and digital resources, and have developed huge networking systems to distribute and mange grey literature. Because of the scarcity of a global standardized organization system for grey literature and often limited access to computer technology, however, awareness of existence and access to grey literature is still seriously lacking, particularly in developing countries. Based on a survey of selected Pakistani NGOs from various sectors, this study proposes a new model. This paper explains the current usage patterns of grey literature in Pakistani organizations, then assesses their needs and resources for grey literature and finally recommends anew standardized model for organizing grey literature in the developing world. In this model a separate subject and classification scheme to control various types of grey literature, a shelving arrangement system and a networking system have been introduce
