The Reader Collision Problem (RCP) is a bottle-neck decreasing the reading efficiency in multiplereader RFID systems. This paper proposed a novel anti-collision protocol – DRA (Distributed Reservation-based Anti-collision) protocol to solve the RCP in multiple-reader RFID systems. Temporal Cluster Headers (TCHs) are dynamically selected among the potentially interfered readers in DRA protocol. ...

The technology of Radio Frequency IDentification (RFID) enables many applications that rely on passive, battery–less wireless devices. If a RFID reader needs to gather the ID from multiple tags in its range, then it needs to run an anti–collision protocol. Due to errors on the wireless link, a single reader session, which contains one full execution of the anti–collision protocol, may not be su...

This article describes reproducibility of a single-step automated β-galactosidase, and the equivalence of its data to the traditional assay ("Experiments in Molecular Genetics" [1]). This was done via a pairwise comparison of both methods using strains with Miller Unit [MU] values ranging from 0 to over 2000. The data presented in this article is associated with the research article entitled "A...

In an RFID system, tags can be identified by a reader when they are within the interrogation zone of the reader. Collisions occur when tags using backscatter technology report their IDs to the reader at the same carrier frequency simultaneously. The performance of tag identification is degraded by collisions, so it is important to address the tag collision problem. Several anti-collision protoc...

This paper investigates the potential interactions between reader and tag anti-collision algorithms of passive RFID (radio frequency identification) systems. Conventionally, reader and tag anti-collision algorithms are designed by assuming that they are independent from each other. In practice, however, readers and tags usually operate in the same frequency band. Therefore, contention between t...

BACKGROUND AND PURPOSE Treating MS with disease-modifying drugs relies on accurate MR imaging follow-up to determine the treatment effect. We aimed to develop and validate a semiautomated software platform to facilitate detection of new lesions and improved lesions. MATERIALS AND METHODS We developed VisTarsier to assist manual comparison of volumetric FLAIR sequences by using interstudy regi...
