We address the problem of blind identification of a convolutive Multiple-Input Multiple-Output (MIMO) system with more inputs than outputs, and in particular, the 3-input 2-output case. We assume that the inputs are temporally white, non-Gaussian distributed, spatially independent. Solutions for the scalar MIMO case, within scaling and permutation ambiguities, have been proposed in the past, ba...

In this paper, presents the feasibility of deploying RFID for the steel industry as a tool to reduce the production costs. Steel industry that is applicable to RFID-based tracking management system is proposed. The results of this paper proved that the recognition of 100 per cent came from the material input and output and the location, the location indicated 99 per cent detection rate. Therefo...

Input level fusion and output level fusion methods are compared for fusing Mel-frequency Cepstral Coefficients with their corresponding delta coefficients. A 49 speaker subset of the King database is used under wideband and telephone conditions. The best input level fusion system is more computationally complex than the output level fusion system. Both input and output fusion systems were able ...

This study investigates the role of financial structure on the volatility of four asset prices in Korea. First, historical development of size, activity and efficiency of financial structure is investigated and development of non-bank financial institutions analyzed for the last three decades. Second, using the concept of bank-based and market-based financial structure, it is shown that there e...

Sweep frequency response analysis is a major advance in transformer condition analysis. Frequency response is performed by applying a low voltage signal of varying frequencies to the transformer windings and measuring both the input and output signals. The ratio of these two signals gives the required response. This ratio is called the transfer function of the transformer from which both the ma...

This paper considers three pairs of circuit schemes for RF rectification. Given finite available power from RF source and load resistance, we formulate DC output power and efficiency of each scheme. Resultant formulas find that load-to-source resistance ratio R/r dominates the circuit performance. Maximum efficiency reaches 81.1% at R/r = 1 for single-diode half wave rectifiers. It also reaches...

An improved RF–dc converter based on a class-E rectifier with wide-dynamic-range input matching is presented. The input impedance is controlled by two varactor diodes to compensate for impedance changes with RF input power and dc loading conditions. The RF–dc converter achieved a peak efficiency of 60% and an S11 less than −20 dB over an input RF power range of 12 dB and an operating battery vo...

Motivated by the problem of out-of-shelf (OOS) in retail industry and the emergence of RFID (Radio Frequency Identification) technology, this paper investigates the impact that the adoption of RFID has on the quality of information utilized during the shelf replenishment process. A RFID-integrated information system (IS) with three alternative implementation scenarios is proposed to enhance the...

This paper presents a new design for an input impedance antenna automatic matching system. In order to achieve this main objective, it is necessary to accomplish several intermediate tasks. On the one hand, a study about the implementation of a generic electronically tunable impedance synthesizer is carried out. Then, a prototype based on the research is constructed, and its characteristics and...
