A long range, periodically ordered array of discrete nano-features (10), such as nano-islands, nano-particles, nano-wires, non-tubes, nano-pores, nano-composition-variations, and nano-device-components, are fabricated by propagation of a self-assembling array or nucleation and growth of periodically aligned nano-features. The propagation may be induced by a laterally or circularly moving heat source, a stationary heat source arranged at an edge of the material to be patterned (12), or a series of sequentially activated heaters or electrodes. Advantageously, the long-range periodic array of nano-features (10) may be utilized as a nano-mask or nano-implant master pattern for nano-fabrication of other nano-structures. In addition, the inventive long-range, periodically ordered arrays of nano-features are useful in a variety of nanoscale applications such as addressable memories or logic devices, ultra-high-density magnetic recording media, magnetic sensors, photonic devices, quantum computing devices, quantum luminescent devices, and efficient catalytic devices.

Analysis of a vehicle is performed using multi-dimensional infrared image data acquired for the vehicle. A component of the vehicle can be identified within the infrared image data, and the infrared image data for the component can be analyzed to determine whether any condition(s) are present on the vehicle. One or more actions can be initiated in response to a determination that a particular condition is present. Additionally, visible image data can be used to supplement the infrared image data. Still further, infrared image data for similar components imaged concurrently with the component can be used to identify whether any condition(s) are present on the vehicle. Unlike prior art approaches in the rail industry, the analysis can be performed on rail vehicles within a classification yard.
