The passive Radio Frequency Identification (RFID) technology in Ultra High Frequency (UHF) band is more and more mature and adopted in many heterogeneous scenarios mainly to optimize business processes related to logistics and supply chain management. In addition, the research community has started to experiment this technology also in new applicative fields, such as the tracking of laboratory ...

Introduction The rapid pace at which the technological innovations are being introduced in the world poses a potential challenge to the retailer, supplier, and enterprises. In the field of Information Technology (IT) there is a rapid growth in the last 30 years (Want 2006; Landt 2005). One of the most promising technological innovations in IT is radio frequency identification (RFID) (Dutta et a...

of Dissertation Presented to the Graduate School of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy SYNCHRONIZATION IN IMPULSE RADIO ULTRA-WIDEBAND COMMUNICATION SYSTEMS By Sandeep Aedudodla December 2006 Chair: Tan F. Wong Major Department: Electrical and Computer Engineering Ultra-wideband (UWB) communication has recently generated a...

In 2004, McLaughlin et al. discovered a phenomenon in the radio emission of PSR J0737−3039B (B) that resembles drifting sub-pulses. The repeat rate of the sub-pulses is equal to the spin frequency of PSR J0737−3039A (A); this led to the suggestion that they are caused by incidence upon B’s magnetosphere of electromagnetic radiation from A. Here we describe a geometrical model which predicts the...

We introduce a new graphical model for tracking radio-tagged animals and learning their movement patterns. The model provides a principled way to combine radio telemetry data with an arbitrary set of userdefined, spatial features. We describe an efficient stochastic gradient algorithm for fitting model parameters to data and demonstrate its effectiveness via asymptotic analysis and synthetic ex...

The use of RFID (radio-frequency identification) in the retail supply chain and at the point of sale (POS) holds much promise to revolutionize the process by which products pass from manufacturer to retailer to consumer. The basic idea of RFID is a tiny computer chip placed on pallets, cases, or items. The data on the chip can be read using a radio beam. RFID is a newer technology than bar code...

Location estimation in Wireless networks has become an important feature for improvement in public safety service. Its potential applications include location sensitive billing, asset tracking, fraud protection, mobile yellow pages, fleet management, etc. Several location techniques using terrestrial wireless network elements and radio signals have been proposed over the years, but multipath pr...

Radio science data collected from NASA’s Deep Space Networks (DSNs) are made available in various formats through Planetary Data System (PDS). The majority of these packed complex formats, making them inaccessible to users without specialized knowledge. In this paper, we present a Python-based tool that can preprocess the closed-loop archival tracking files (ATDFs), produce Doppler and range ob...

Due to advances in silicon manufacturing technology, Radio Frequency Identification (RFID) systems are useful in many applications such as automobile immobilizers, animal tracking, payment systems, automatic toll collection and inventory management. As RFID systems use both radio and wire communication, security issues become a critical concern. However, even if security and privacy solutions h...

This paper suggest the idea of developing an automatic Radio Frequency Identification (RFID)-based system for library search and to observe the current literature to define whether current technology and developed RFID-based systems are supportive for building that. To fully understand its key points, implementations, risks, and benefits, the fundamentals of radio frequency are to be recognized...
