A machine vision approach to the grading of crushed aggregate

The grading of crushed aggregate is carried out usually by sieving. We describe a new image-based approach to the automatic grading of such materials. The operational problem addressed is where the camera is located directly over a conveyor belt. Our approach characterizes the information content of each image, taking into account relative variation in the pixel data, and resolution scale. In feature space, we find very good class separation using a multidimensional linear classifier. The innovation in this work includes (i) introducing an effective image-based approach into this application area, and (ii) our supervised classification using wavelet entropy-based features.

Investment and Capitalization of Firms in the USA

In the USA today, the precipitous rise of new financial mechanisms for capitalisation of firms as well as the merger and acquisition of others, especially risk equity capital through venture capitalist and investment banking, has sparked growth and helped to bring the economy out of the 1990s recession into a robust continuous growth pattern well positioned for the next century. The scenario is not new. For the venture capitalists of ''Silicon Valley'' in California, the experience is not new. They have seen the new industries arise before, like a phoenix from ashes of ruin, despair and even failure. Venture capital poured into high tech start-up companies has been an enormous source of financial support for the entrepreneurs who head new and growing companies. The mid-1990s marked the most dramatic increase yet recorded. Indicators, such as the NASDAQ document, outlined the solid and continuous growth in high tech industries. The paper discusses investment in US corporations within the context of governance and management of the company. Discussion about the various forms of finance are related to the organisation and management of the US corporation. Critical to any firm today are its ability to find innovative, new products or services. A growing literature on resource-base framework for analysis will be discussed as part of the firm's development of research for commercialisation. The results of a recent survey further shed light on the relationship between corporate financial management and allocated resources for research and development as the ''engine'' for new product development and therefore corporate market share and growth. The conclusion is that more financial mechanisms will be created and changed within US corporate systems to adjust, grow, and expand companies in the global economic arena, as the inevitable economic pattern leads to mergers, consolidations, and increasing cooperation and alliances among firms.

Molecular Plasmonics with Tunable Exciton-Plasmon Coupling Strength in J-Aggregate Hybridized Au Nanorod Assemblies

Controlling coherent electromagnetic interactions in molecular systems is a problem of both fundamental interest and important applicative potential in the development of photonic and opto-electronic devices. The strength of these interactions determines both the absorption and emission properties of molecules coupled to nanostructures, effectively governing the optical properties of such a composite metamaterial. Here we report on the observation of strong coupling between a plasmon supported by an assembly of oriented gold nanorods (ANR) and a molecular exciton. We show that the coupling is easily engineered and is deterministic as both spatial and spectral overlap between the plasmonic structure and molecular aggregates are controlled. We think that these results in conjunction with the flexible geometry of the ANR are of potential significance to the development of plasmonic molecular devices.
