The use of high resolution IKONOS imagery should make it possible to extract urban features like buildings and roads more easily than conventional satellite image data. This work examines the synergetic ability of using spectral information from multispectral data in combination with spatial information from panchromatic data in urban land cover mapping using IKONOS Imagery. In this work we tri...

A direct sequence optical code division multiple access technique is investigated. This paper introduces, first, the principles definitions of Code Division Multiple Access in radio communications. After that, the performances of Optical Code Division Multiple Access are evaluated in association with a realistic amplified optical channel model. To determine the performances obtained by this com...

Pharmaceutical drug screening and research into diseases call for significant improvement in the effectiveness of current in vitro models. Better models would reduce the likelihood of costly failures at later drug development stages, while limiting or possibly even avoiding the use of animal models. In this regard, promising advances have recently been made by the so-called “organ-on-chip” (OOC...

-In wireless optical system, CDMA suits well for high bit rate systems where good security is needed and mobility is not important. It would be economical when compared to radio frequency band and much safer since there is no electromagnetic effect. Infrared systems are used for its widest bandwidth and are not affected by radio transmission. The advantage of the prime code and the security iss...

In this paper a new method to construct zero cross correlation code with the help of Pascal's triangle pattern called Pascal's Triangle Matrix Code (PTMC) for Spectral Amplitude Coding Optical Code Division Multiple Access (SAC-OCDMA) system is successfully developed. The advantages of this code are simplicity of code construction, flexibility of choosing code weight and number of users. The nu...

There has been a recent upsurge of interest in applying Code Division Multiple Access (CDMA) techniques to optical networks. Conventional spreading codes for OCDMA, known as optical orthogonal codes (OOC) spread the signal in the time domain only, which often results in the requirement of a large chip rate. By spreading in both time and wavelength using two-dimensional OOCs, the chip rate can b...

One of the many applications organ-on-a-chip (OOC) technology is study biological processes in human induced pluripotent stem cells (iPSCs) during pharmacological drug screening. It paramount importance to construct OOCs equipped with highly compact situ sensors that can accurately monitor, real time, extracellular fluid environment and anticipate any vital physiological changes culture. In thi...

This paper investigates the Parallel Interference Cancellation technique in Direct Sequence Optical Code Division Multiple Access (DS-OCDMA) system. In the proposed system, the estimated interference is removed from the received signal. We have developped a new approach to obtain the analytical expression of error probability in chip synchronous case, for Optical Orthogonal Codes (OOC). We have...

A new puke position modulation code division multiple access (PPM-CDMA) system is proposed for an indoor optical wireless channeL As a signature sequence for CDMA an optical orthogonal code (OOC) is used To reduce multiple access interference, two interference cancellation schemes are employed: decorrelating detection and successive interference cancellation (SIC). The bit error rate of the pro...

1,1 0-Ferrocene dicarboxylic acid pyridin-4-yl ester (1) is prepared from 1,1 0-ferrocene dicarbonyl chloride and 4-hydroxypyridine. This new bidentate ferrocenoyl ligand reacts with the monocationic complex [(g-p-cymene)2Ru2(l-OH)3] + to give the dicationic complex [(g-p-cymene)2Ru2(l-OH)2(1,1 0(NC5H4–OOC)2–Fc)] 2+ (2) (Fc: C5H4–Fe–C5H4), isolated as a tetrafluoroborate salt. The single-crysta...
