We present a system for automatically identifying the native language of a writer. We experiment with a large set of features and train them on a corpus of 9,900 essays written in English by speakers of 11 different languages. our system achieved an accuracy of 43% on the test data, improved to 63% with improved feature normalization. In this paper, we present the features used in our system, d...

In this paper, we present an overview of UHF RFID tag performance characterization. We review the link budget of RFID system, explain different tag performance characteristics, and describe various testing methods. We also review state-of-the art test systems present on the market today.

RFID technology is an area currently undergoing active development. An issue, which has received a lot of attention, is the security risks that arise due to the inherent vulnerabilities of RFID technology. Most of this attention, however, has focused on related privacy issues. The goal of this chapter is to present a more global overview of RFID threats. This can not only help experts perform r...

This paper focuses on the new trends to optimize costs in healthcare supply chain operations that include virtual centralization of supply chains, supply utilization management practices, use of RFID technologies, use of analytics, streamlining workflow etc. The application of these techniques can provide affordable healthcare solutions in developing countries.

Efficient Cardinality Counting for Large-scale RFID Systems

In the aerospace industry, a maintenance history is not that easy to maintain. It can be an arduous task trying to find the part number on a component especially when the component has already been assembled and the number is the back. However, searching for the number is not the only issue in tracking the maintenance history. Since the number is written down by a person, human errors are prone...

Tag collision is one of the most important issues in RFID systems and many tag anti-collision protocols were proposed in literature. But some kind of these protocols like Tree-based protocols (specifically Query tree) which its performance depends on tag ID length and construction, have some issues like ID distribution. In this paper we discuss about Query tree protocol which may influenced by ...

Native Language Identification (NLI), which tries to identify the native language (L1) of a second language learner based on their writings, is helpful for advancing second language learning and authorship profiling in forensic linguistics. With the availability of relevant data resources, much work has been done to explore the native language of a foreign language learner. In this report, we p...
