Paper presents a method for analysis of UHF RFID tags. After a brief overview of RFID system and UHF tags an electromagnetic (EM) simulation of tags in WIPL-D software was conducted. Electrical matching was performed after which tags were excited by a uniform EM wave, induced powers were measured and tag characteristics were compared.

Collaborative tagging has grown on the Internet as a new paradigm for web information discovering, ltering and retrieval. In the physical world, we use visual tags: labels readable by smartphones with cameras. While visual tags are usually related to a web site address, collaborative tagging, instead, provides updated, recommended information contributed and shared by users. In this paper we in...

Several expert systems have been proposed to address the sparsity of tags associated with online content such as images and videos. However most of such systems either necessitate extracting domain-specific features, or are solely based on tag semantics, or have significant space requirements to store corpus based tag statistics. To address these shortcomings, in this work we show how ontologic...

MAE and MAI are lightweight annotation and adjudication tools for corpus creation. DTDs are used to define the annotation tags and attributes, including extent tags, link tags, and non-consuming tags. Both programs are written in Java and use a stand-alone SQLite database for storage and retrieval of annotation data. Output is in stand-off XML.

We describe a new non-contact high capacity optical tagging technique based on the use of nanostructured barcodes. The tags are generated from a number of superimposed diffraction gratings. With one-dimensional diffraction, capacity for up to 68,000 distinguishable tags has been demonstrated, with a theoretical capacity of up to 109 tags. Extension into two dimensions increases this theoretical...

We present an algorithm for automatically clustering tagged videos. Collections of tagged videos are commonplace, however, it is not trivial to discover video clusters therein. Direct methods that operate on visual features ignore the regularly available, valuable source of tag information. Solely clustering videos on these tags is error-prone since the tags are typically noisy. To address thes...

RFID authentication on large numbers of tags or tag groups has attracted many researchers’ attention as an extension of initial one-or-two-tags scenarios. Due to demands of RFID application in supply chain, various proofs are proposed in the purpose of solving existing problems of grouping tags identification. However, it is proved that verifiers in these proofs are not aware of abnormal relati...

Using a simple method of mass production of green carbon nanotags (G-tags) from harmful cyanobacteria, we developed an advanced and efficient imaging platform for the purpose of anticancer therapy. Approximately 100 grams of G-tags per 100 kilograms of harmful cyanobacteria were prepared using our eco-friendly approach. The G-tags possess high solubility, excellent photostability, and low cytot...

Although social, collaborative classification through tagging has been the focus of recent research, the effect of multilingual tags is often overlooked. This work presents an early exploratory study of the production and consumption of multilingual tags in a European educational K-12 context. The data, produced by teachers bookmarking and tagging learning resources during three month period, w...

ABSTR.ACT We will describe an Earley-type parser for Tree Adjoining Grammars (TAGs). Although a CKY-type parser for TAGs has been developed earlier (Vijay-Shanker and :Icshi, 1985), this is the first practical parser for TAGs because as is well known for CFGs, the average behavior of Earley-type parsers is superior to that of CKY-type parsers. The core of the algorithm is described. Then we dis...
