Electric vehicle (EV) charging must be optimised for grid load while guaranteeing that drivers' schedules and range requirements are met. A system encompassing EV owner input via a mobile application, an aggregation middleware, a charge scheduling and vehicle-to-grid (V2G) operation algorithm and a radio-frequency identification reader is proposed. The algorithm's parameters and effectiveness are presented and discussed using simulation results. Simulation results show the algorithm to effectively optimise charging and V2G operation for a given electricity price curve. The proposed system is shown to alleviate grid load during peak hours, take advantage of off-peak charging benefits and generate revenue for the parking garage operator.

The continuous growth of health care services expenses urges U.S. government to take actions. The adoption of Information Technology, and especially RFID (Radio Frequency IDentification) allow hospitals to re-engineer their processes in order to reduce costs, maintaining the same level of service to the patients. Information technology represents a core element of the service itself; therefore a service design approach is believed to improve the adoption rate of RFID in hospitals. The main goal of the present study is to propose an RFID based service platform for hospitals, which is consistent with a service science driven design approach. A survey of 33 California based hospitals has been used to identify the user requirements of the hospitals. Later, a business process re-engineering for hospitals is proposed. Firstly the different actors involved in the health care services, along with their relationships in terms of information flows, are identified. This leads us to identify the various operations in a hospital setting that have a potential to be streamlined by introducing RFID technology. Having introduced these operations, we theorize a customizable RFID service, which can be implemented sequentially by each hospital according to its individual conditions such that it suits them most.

Radio-frequency identification (RFID) has a great number of unfulfilled prospects. Part of the problem until now has been the value proposition behind the technologyVit has been marketed as a replacement technique for the barcode when the reality is that it has far greater capability than simply non-line-of-sight identification, towards decision making in strategic management and reengineered business processes. The vision of the internet of things (IOT) has not eventuated but a world in which every object you can see around you carries the possibility of being connected to the internet is still within the realm of possibility. However incremental innovations may see RFID being sold as a service (much like photocopiers are maintained today) than a suite of technologies within a system that are sold as individual or bundled packaged components. This paper outlines the vision for such a product service system, what kinds of smart applications we are likely to see in the future as a result, and the importance of data management capabilities in planetary-scale systems.

In this paper, an RFID architecture has been presented where the traditional role of the localised middleware has been distributed to the RFID reader and a cloud based web service supported by a web based user interface, eliminating the role of the former. Such an interface allows a user to control and carry out all of the major RFID related operations in a typical supply chain based situation remotely. Load testing was carried out to test the processing capability of the RFID reader based Reader Resident Application and the Reader Web Service for both large scale tag traffic and large scale event generation and processing. Different schemes were proposed for small and large scale event processing. These results are presented to demonstrate the applicability of this architecture for multiple RFID based operations.
