With a growing number of consumers utilizing the Internet, companies have foreseen a consumer demand for high-speed wireless access. Since current mobile cellular systems can transfer at most 115.2 kbps per user, a third generation of mobile cellular service has been under development by various organizations since 1997. This new generation of technology will support data rates up to 2 Mbps for...

A national comparison of dc resistance at 10 M and 1G level was organized by the Electromagnetic Division of National Institute of Metrological Research (INRIM, Italy) and piloted by the same Division. This comparison took place between January and April of 2008 with the participation of 8 secondary Laboratories accredited by the Italian Accreditation of Calibration Laboratories Service (SIT). ...

This paper presents competent Method for Optimizing Artificial Neural Network Using Quantum Based Algorithm. In the evolutionary process, the Quantum bits refined so that the probability of finding the optimal network is increased. The probability representation reduced the non positive impact of the permutation problem and the risk of the potential network. To finds near-optimal connection wei...

Long Term Evolution (LTE) is the next step towards in the arena of 3G cellular wireless services. Expected in the 2008 time frame, it is a 3GPP standard which provides an uplink transmission rate of up to 50 megabits per second (Mbps) and a downlink transmission rate of up to 100 Mbps. LTE evolved from an early 3GPP wireless standard identified as Universal Mobile Telecommunication System (UMTS...

⎯The IEEE 802.16d communication standard uses orthogonal frequency division multiplexing (OFDM). In the widely used OFDM systems, the fast Fourier transform (FFT) and inverse fast Fourier transform pairs are used to modulate and demodulate the data constellation on the sub-carriers. In this paper, a high level implementation of a high performance FFT for OFDM modulator and demodulator is presen...

to the extent that a society is to work, there exist a need for a cooperative process, including weber’s and merton’s note of common means and goals. but at the same time, there exist no societal process without involving conflict; (conflict in a dynamic and dialectical sense.) dealing with this problematic situation the emergence of “division of labor”, as a compulsive social differentiation, ...

conclusions our underlying hypothesis is that recapitulating the three-dimensional early embryonic structure, in order to reproduce better in vitro the three-dimensional morphogenetic-like re-arrangements, would improve cells differentiation, when in vivo transplanted; moreover, it could be used as a simplified cancer disease model and reliable drug evaluation method as well. results the proces...

This study proposed a novel methodology for designing bandpass multiplexer-integrated power dividers (PDs) that provide frequency division, selection, and division. New coupling schemes the PDs were presented to ensure multifunctionality compactness. Miniaturization was achieved through common resonator technique. Dual-mode stub-loaded resonators serving as various channel passbands used in PD ...

This paper describes a proposed Code Division Multiple Access (CDMA) digital cellular network by QUALCOMM. The main characteristics of the access method are described shortly and the simple capacity estimate is given. The power control mechanisms, the handoff algorithm and the privacy measures are described. The description also contains the layered description of communication services with th...
