Tiling light sheet selective plane illumination microscopy using discontinuous light sheets
Tiling light sheet selective plane illumination microscopy (TLS-SPIM) improves the 3D imaging ability of SPIM by using a real-time optimized tiling light sheet. However, the imaging speed decreases, and size of the raw image data increases proportionally to the number of tiling positions in TLS-SPIM. The decreased imaging speed and the increased raw data size could cause significant problems when TLS-SPIM is used to image large specimens at high spatial resolution. An exemplary aspect solves this problem. Discontinuous light sheets created by scanning coaxial beam arrays synchronized with camera exposures are used for 3D imaging to decrease the number of tiling positions required at each image plane without sacrificing the spatial resolution. One exemplary aspect investigates the performance of the method via numerical simulation and discuss the details thereof. |

System and method for configuring analytic rules to equipment based upon building data
An energy management system is disclosed for optimizing energy usage of HVAC equipment in a building complex. The energy management system is configured to be integrated into an existing Building Automation System (“BAS system”) in order to process the data points in a less time consuming and efficient manner relative to known systems that map one point at a time. The BAS system data points are “point mapped”, i.e., uploaded to a file in the “cloud”, and are updated continuously as a function of time and deposited in a “bucket” in which the data points are unfiltered. These data points can then be filtered by node path and equipment in order to bulk tag equipment and bulk tag points in each of the buildings. These bulk tagged points data points can then be linked to specific rules in an analytical rules library. The system automatically applies predetermined analytical rules to tagged HVAC data points without specific knowledge of the rule by the user. These analytical rules are used to determine energy usage for each type of equipment and are pre-stored in the cloud. By selecting an equipment type, the correct analytical rule is automatically applied in bulk to the selected HVAC equipment type, and a report may be selectively generated for the selected piece(s) of HVAC equipment. |

Control apparatus for vehicle
Torque reduction control is executed for temporarily reducing a torque capacity of a reaction engagement device during a transition of a shift. The reaction engagement device is maintained in an engaged state from before the shift to after the shift such that a predetermined rotating element in an automatic transmission bears a reaction caused by progress of the shift resulting from a change of an engaging-side engagement device into an engaged state.

Polar solvent solution and production method thereof
A polar solvent solution of the present invention is a polar solvent solution in which a solute containing a polyamine acid is dissolved in a polar solvent. An inorganic salt is added to the solution, and a mole ratio of moisture to the inorganic salt in the solution is 2.5×m×n or less, where m represents the number of cations forming the inorganic salt and n represents a charge number of the cation. A production method of the present invention is a method for producing the above solution, including: changing at, least one of a moisture content and a content of the inorganic salt in the solution to adjust a viscosity of the solution. Thus, the present invention provides a polar solvent solution whose viscosity can be easily adjusted to a desired value and thus enables stable spinning and casting when used as dopes for spinning, film, etc., and methods for producing the same. |
