Abstract: Computer-implemented systems and methods are provided for reducing a number of options presented to a user where the options have characteristics that are arranged in a multi-dimensional hierarchical space. A system and method can be configured to identify common dimensions using dimension nodes in dimensional points and identify compatible nodes for each dimension in the multi-dimensional hierarchical space by determining whether an association exists. Compatible pairs of surviving points are generated after applying each of the compatible nodes from the common dimensions. Greatest lower bounds (GLBs) are computed for each of the generated compatible points, and a set of options is generated comprising points from the generated compatible points and the computed GLBs.

Abstract: A sensing device that produces a Raman signal includes micro-rods or nano-rods arranged on a substrate in a two-dimensional (2D) array, each of the rods having a length in a single row being substantially the same, with the rod length of each row being different from the rod length of each other row. Each row of rods has a respective resonant vibration frequency that varies from row to row. A source of vibration energy, operatively connected to the substrate, excites vibration in each of the rods such that a responding row resonates when an exciting frequency approaches the resonant vibration frequency of the responding row. A method includes exposing the 2D array to a light source and analyzing Raman scattering at each rod of the 2D array to render a Raman map.
