Abstract: A system includes a first most probable cause (MPC) module, a second MPC module, and an integrated MPC module. The first MPC module is configured to determine a first most probable cause of an issue on a vehicle based on at least one service procedure for the vehicle. The second MPC module is configured to determine a second most probable cause of the issue based on repair data for other vehicles. The integrated MPC module is configured to determine an integrated most probable cause of the issue based on the first and second most probable causes.

Abstract: A reaction pathfinder system can leverage historical chemical reaction data and determine a synthesis route in a reaction network. The reaction pathfinder system can account for various performance criteria of chemical reactions such as a highest yield for a molecule or a minimal number of reaction steps. A reaction pathfinder system receives a user request for a synthesis route including one of a user-specified molecule or a user-specified reaction. The reaction pathfinder system may then query a reaction network that has various synthesis routes and represents reactions of reactants to produce respective molecules. The reaction network may be composed of molecule nodes and reaction nodes. The reaction pathfinder system determines, using the reaction network, the synthesis route from the synthesis routes to fulfill the user's request.

Abstract: Systems and methods for processing crude methanol are disclosed. A crude methanol stream, comprising methanol and paraffin wax, is produced from syngas (carbon monoxide, carbon dioxide, and hydrogen). The crude methanol stream is cooled to form a partially condensed crude methanol stream, which is further separated in a vapor-liquid separator to form a liquid stream and a gas stream. The liquid stream is further cooled in a dewaxing unit to remove paraffin wax. The dewaxing unit includes two or more cooling units arranged in parallel such that when one of the cooling units is offline for cleaning, the methanol system does not need to be shut down.

Abstract: A board for testing DVD (Digital Versatile Disc) ROM (Read Only Memory) chip-set and associated circuit for generating radio frequency signals with phase difference are provided. The circuit includes signal potential dividers, high pass filters, and a phase shifter. The circuit receives a digital input signal, which has a predetermined frequency, generated by a chip test device. The radio frequency signals with phase difference for testing the analog circuit block of DVD ROM chipset are generated according to the received digital input signal. Therefor, the high temperature operating life test for optical disc drive chips can be achieved.

Abstract: A method for post-treating a dry-etched metal film is provided. The dry-etched metal film includes an unetched portion covered by a photoresist and an etched portion exposed from the photoresist and having thereon an etching by-product. According to the method, a stripping agent is used to remove the photoresist on the unetched portion, while reacting the stripping agent with the etching by-product to form a passivation layer on the exposed metal film. Then, a washing agent is used to remove the passivation layer after the photoresist is removed. A system for performing combined etching and stripping procedures of a metal film is also provided. The system comprises dry-etching chambers, stripping and cleaning chambers and a transportation device. In the stripping and cleaning chambers, the photoresist on the unetched portion is removed by a stripping agent and a passivation layer is formed on the etched portion by reacting the stripping agent.
