2/sup L/-symbol 8-dimensional constellations

Abstract: By utilizing four consecutive symbol periods at a time, eight-dimensional constellations can be generated. Here, such 2/sup L/-symbol constellations (8D-L) are proposed, where L is any integer >or=8. Actually, two constellations are given for L=8: one which requires an optimum detector, 8D-8B, and the other, 8D-8A, which can be detected by the general detector provided for 8D-L. It is demonstrated that 8D-8B provides 0.37-dB improvement as far as signal-to-noise ratio is concerned over 8D-8A which, in turn, provides 1.78 dB improvement over the corresponding QPSK (quadrature-phase-shift-keying) system. Furthermore, 8D-12 is better than 8-QAM (quadrature amplitude modulation)/by 3.17 dB, whereas 8D-16 achieves 2.55 dB improvement over 16-QAM. >

Homotopy analysis method applied to second-order frequency mixing in nonlinear optical dielectric media

Abstract: The classical problem of three-wave mixing in a nonlinear optical medium is investigated using the homotopy analysis method (HAM). We show that the power series basis builds a generic polynomial expression that can be used to study three-wave mixing for arbitrary input parameters. The phase-mismatched and perfectly phase matched cases are investigated. Parameters that result in generalized sum- and difference-frequency generation are studied using HAM with a power series basis and compared to an explicit finite-difference approximation. The convergence region is extended by increasing the auxiliary parameter.

Generation Property: A Consideration of Customary Land Tenure in The Bahamas

Abstract: Bahamian land ownership is linked closely with the idea of family. Many groups of kin lay claim to large estates throughout the Bahamian archipelago, and this property becomes a unifying emblem of the kin group as a whole. Generation property unites groups of relatives not only by serving as a symbolic connection to the land but also by providing them with what is potentially a very real source of capital, profit, and power. As the same time, it serves as a flexible resource to be manipulated as necessary by individuals, each of whom may make multiple claims on different pieces of land. In this regard, generation property is similar to the Afro-Caribbean tradition of family land, but the Bahamas cannot be judged simply as a variant of the Caribbean model. Family land is both scarce and a marker of ex-slave resistance and Afro-Caribbean solidarity. Bahamian generation property is not owned only by the descendants of the slaves, unlike Caribbean family land, and as such it is a symbolic resource for white and black Bahamians alike, and is also a potential provider of economic, social and political wealth.

Profiling Boundary Layer Aerosols in The Bahamas at Various Time of Year using a Camera-based Imaging Lidar

Abstract: A wide-angle camera-based bistatic imaging lidar is used to profile altitude dependent aerosol extinction at various time of year in the Bahamas. The instrument provides excellent altitude resolution in the near ground regions.
