Battery-operated Light Emitting Diodes (LEDs) are often arranged in parallel strings in a lighting fixture due to the high voltage gain required in case of a series type connection. Yet, current sharing is prevalent in the parallel configuration due to the large forward voltage tolerance of high-power LEDs resulting in uneven light output and premature failure when they are “overdriven”. Current-matching...
Deriving deadlines and periods for update transactions so as to maintain timeliness and data freshness while minimizing imposed workload has long been recognized an important problem in real-time database research. Despite years of active research, the state-of-the-art still has much room for improvement, particularly for periodic transactions scheduled by the Earliest Deadline First (EDF) algorithm...
In many telecom and web applications, there is a need to identify whether data objects in the same source or different sources represent the same entity in the real-world. This problem arises for subscribers in multiple services, customers in supply chain management, and users in social networks when there lacks a unique identifier across multiple data sources to represent a real-world entity. Entity...
