Abstract: An apparatus and method are described for producing and harvesting algae. The orientation of the production substrates is critical for maximizing production as a function of water area utilized. By employing an array of algae production substrates in a vertical configuration relative to the water surface, the yield of algae production per area of open water is increased substantially relative to prior art algae production systems.

Abstract: The invention described herein details a protocol to improve analysis and peak identification in spectroscopic data. Bayesian methods are used to automatically identify peaks in data sets. After identifying peak shapes, the method tests the hypothesis that a given number of peaks is found within any given data window. If a peak is identified within a given window, then the likelihood function is maximized in order to estimate peak position and amplitude. This process yields a spectrum with high resolution and minimal artifacts. The method described herein is particularly useful for identifying peaks in data sets obtained from spectroscopy.

Abstract: A method of manufacturing a circuit assembly is provided. The circuit assembly (10) manufactured according to the present invention includes a circuit board (12) and a heat sink (22). The circuit board (12) has a first side (16) and a second side (20), and each of these sides (16, 20) has one or more electronic components (14, 18) mounted thereon. The heat sink (22) also includes a first side (34) and a second side (43), the first side (34) having a recessed portion (24) therein. The method of manufacturing the circuit assembly (10) includes the step of dispensing a heat curable adhesive (26) between the mating surfaces (30, 32) of the second side (20) of the circuit board (12) and the first side (34) of the heat sink (22). The method also includes the step of positioning the circuit board (12) such that the component (18) on its second side (20) is aligned with the recessed portion (24) of the heat sink (22).

Abstract: The present invention relates to an apparatus for providing second harmonic generation from a single beam in an isotropic medium. An isotropic medium having a two-photon transition between a first level and a second level with a quadrupole moment therebetween is exposed to a beam of laser radiation. The photons in the laser beam have an energy which is substantially equal to one-half the energy difference between the first and second levels.

Abstract: A continuous length of aluminum is anodized during passage through an anodizing electrolyte and then colored during passage through an inorganic coloring electrolyte, in which a counterelectrode is immersed. In the electrolytic coloring stage alternating current with a superimposed D.C. compound is preferably passed between the anodized aluminum and the counterelectrode when the electrolyte is appropriate for such treatment. The alternating current circuit for the electrolytic coloring stage is preferably completed via an electrode immersed in the anodizing electrolyte at a position facing substantially unanodized aluminum so as to effect a liquid contact.

Abstract: In a process for electroplating aluminum articles, the article is first electrolytically treated, as anode, in a bath consisting essentially of a solution of caustic alkali, and thereafter electroplated. The electrolytic caustic cleaning step, preferably involving agitation, is found specially suitable in composition and indeed is effective in a relatively short time to afford an essentially bare aluminum surface, i.e., free of anodic oxide film and also free of pitting or smut, for advantage in plating, as with tin or other metal. Intermediate steps can be employed such as immersion tinning or zincating and brief electroplating such as a bronze strike; the electrolytic cleaning co-acts well with the intermediate stages, indeed requiring fewer steps over all. Although applicable batchwise, the process is particularly appropriate for continuous electroplating wherein the aluminum wire or strip may pass rapidly through the electrolytic cleaning, intermediate and plating baths in succession.
