Abstract: A method of producing bioethanol in a bioethanol system and a control system for a bioethanol system is disclosed, the control system comprising a controller comprising one or more processors and an interface, wherein the one or more processors are configured to obtain a primary amino nitrogen (PAN) measurement; determine an input scheme based on the PAN measurement; and control one or more input devices of the bioethanol system according to the input scheme.

Abstract: In an embodiment, the disclosed technologies are capable of creating and storing a digital repository capable of storing digital work items; receiving a query; determining historical alpha values and historical beta values for each of at least two candidate search algorithms; for each of the at least two candidate search algorithms, generating a beta distribution using the historical alpha values and the historical beta values as parameters; for each of the at least two candidate search algorithms, computing, using values sampled from the beta distribution, a score that indicates a likelihood of the candidate search algorithm producing a search result that satisfies a relevance criterion; selecting, from the at least two candidate search algorithms, an algorithm that has a score that satisfies a selection criterion; and executing the query using the selected algorithm.

Abstract: Apparatus for sharpening microtome blades comprises a frame and a horizontally sliding carriage reciprocated on the frame by a drive motor and chain drive. The frame carries a high speed motor and a low speed motor which can be selectively coupled to strops and the carriage has a clamp member to clamp a microtome blade for engagement by the strops.
