Recently, augmented ultrahigh frequency radio-frequency identification (UHF RFID) systems have been developed, and they contain additional components that can detect a tag's backscattered response and use this information for the localization of the tag and other applications. The methods currently employed either have poor performance because the detection… (More)
A treatment for depression, chronic pain, cravings, and more--this is the emerging field of transcranial direct current stimulation (tDCS). In tDCS, transcranial means through the skull, and direct current is a weak stimulation current delivered to the brain using noninvasive electrodes placed on the scalp [Figure 1(a)].
An overview of academic and industry solutions to UHF RFID portals.
—In this paper, a summary of performance evaluation is presented, including a discussion of different types of evaluations. The following performance metrics are introduced and defined: speedup, efficiency and scalability. The paper includes a literature survey of performance counters used in multiprocessor systems. A classification is established based on… (More)
