Abstract: In one example embodiment, speech signals are received from a user during a communication session. The received speech signals contain noise including speech of other individuals. The received speech signals are transformed by a machine learning model to produce transformed speech signals corresponding to the received speech signals with a reduced amount of the noise. The machine learning model is trained with speech of the user satisfying a noise threshold and collected during one or more communication sessions.

Abstract: Disclosed is a method for partially regenerating a catalyst for methanol and/or dimethyl ether-to-olefin. The method comprises: introducing a mixed gas into a regenerated region containing a catalyst to be regenerated, and subjecting same to a partial regeneration reaction to obtain a regenerated catalyst, wherein the mixed gas contains water vapor and air; and in the regenerated catalyst, the coke content of at least part of the regenerated catalyst is greater than 1%. The method utilizes the coupling of a mixed gas of water vapor and air to activate a deactivated catalyst, selectively eliminate part of a coke deposit in the catalyst to be regenerated, and obtain a partially regenerated catalyst for methanol-to-olefin. Another aspect of the present invention is that further provided is a method for methanol and/or dimethyl ether-to-olefin by using the partially regenerated catalyst for methanol-to-olefin regenerated by means of the method.

Abstract: Disclosed is a selective field-assisted machining system. The system includes a micron-level high-speed identification module, an in-situ laser assisted module, an ultrasonic vibration module, an energy field loading high-speed control module, and a diamond tool. The micron-level high-speed identification module is used to quickly identify the type of a material substrate of a workpiece to be processed, process the identification information into a corresponding control signal, and send same to the energy field loading high-speed control module to implement selective processing of the workpiece to be processed, i.e. to process brittle particles using in-situ laser assisted machining and to process a soft metal substrate using ultrasonic vibration processing. In the present invention, ultra-precision cutting of brittle particles and a soft metal substrate can be completed at the same time in a single processing process.

Abstract: Submarines with air-charged cargo holds are provided. The pressurize hull of a traditional submarine's cargo hold is replaced by non-pressurized hull, which lowers costs for transporting dry cargo and solves strength and seal problems raised when providing large openings for hatches. The dive depth of the air-charged cargo submarines is not large, so the pressure and volume of the charged air in the cargo hold are limited. This allows problems associated with ensuring the safety of the crew and properly operating the submarine to be easily solved.

Abstract: In space, wastes from humans, animals, and crops can be fully recycled by rearing maggots which will be nourishing feedstuff for feeding animals. These animals and their eggs combined with crop plants will be varied food for humans in space. Water and nutrition left in the residues remaining after rearing the maggots can be recycled and used to fertilize crop plants. Rearing maggots, animals, and crop plants provides a self-sufficient food regenerative system that enables humans to live and work in space on long term missions independent of food from earth.

Abstract: The method apply charge of air to the cargo hold space of the underwater transportation ship or submarine, the pressure hull of cargo hold can be replaced by non-pressure type to achieve lower cost to transport dry cargo and solve strength/seal problems raised by cutting large hatch under water. By adopting the method, various new types of air-charge cargo submarine (ACS) and underwater construction can be designed. The dive depth of ACS is not large. The pressure and volume of the charged air are limited. Therefore the problems of safety, equipment and technology can be easily solved.

These animals and their eggs combines with the crop plants that NASA developed will be varied food for human in space. The water and nutrition leaving in the residues after rearing maggot can be recycled and fertilized by the crop plant again. Rearing maggot and animals combined with crop plants could achieve a self-sufficient food regenerative system from most wastes to enable human to live and work in space-independent of earth-provided food in long term mission.

Abstract: To raise fly larvae (FL) as space food besides crop plants for waste recycling and food production. NASA has been cultivating crop plants as the space food. The feedstuff nutrition from both crew's waste (faces and urine) and crop's waste can be recycled by FL to achieve the goal of efficiently producing nourishing food. The water and nutrition leaving in the dreg after raising HFL can be recycled and fertilized the crop plant again. Raising HFL combining with crop plants could develop a self circular closed system from most wastes to enable human to live and work in space-independent of earth-provided logistics in long duration mission.
