—It is, by now, well known that McIntyre's localized carrier-multiplication theory cannot explain the suppression of excess noise factor observed in avalanche photodiodes (APDs) that make use of thin multiplication regions. We demonstrate that a carrier multiplication model that incorporates the effects of dead space, as developed earlier by Hayat et al.(More)
—The conventional McIntyre carrier multiplication theory for avalanche photodiodes (APD's) does not adequately describe the experimental results obtained from APD's with thin multiplication-regions. Using published data for thin GaAs and Al 0 2 Ga 0 8 As APD's, collected from multiplication-regions of different widths, we show that incorporating dead-space(More)
The dead-space multiplication theory of Hayat and Saleh ͓J. Lightwave Technol. 10, 1415 ͑1992͔͒, in conjunction with the multiplication-width-independent ionization-coefficient model developed by Saleh et al. ͓IEEE Trans. Electron Devices 47, 625 ͑2000͔͒, are shown to accurately predict breakdown voltages for thin avalanche photodiodes of GaAs, InP, In 0.52(More)
—A large number of network applications today allow several users to interact together using the many-to-many service mode. In many-to-many communication, also referred to as group communication, a session consists of a group of users (we refer to them as members), where each member transmits its traffic to all other members in the same group. In this(More)
—In many-to-many communication, a session consists of group of users (we call them members) where each one of the members transmits its traffic to all other members in the group. This paper studies the problem of provisioning many-to-many sessions with sub-wavelength granularities in WDM mesh networks. Our objective is to minimize the number of transceivers(More)

Breast cancer is one of the most common fatal diseases in women. Early detection of malignant breast cancer could be a great help in treating this cancer. Many studies have been performed in order to detect the malignant of cancer tumor till now. It has been tried to contribute more in accurate diagnosis of breast cancer by Support Vector Machine, in this(More)
