Abstract: This invention is a fuel engine piston with an installed bearing and belongs to the field of automotive engine components, specifically relating to a piston for a fuel engine. It includes a piston body, outer arc bearings, pin shaft bolts and sealing rings. It provides a piston for a fuel engine with bearings. The bearings on the piston enable rolling friction during piston operation, replacing sliding friction. This reduces the friction between the piston and the engine cylinder liner, decreases the energy consumption required to overcome friction, and reduces wear on the piston caused by sliding friction.

Abstract: Systems and methods are provided for calculating, using an electronic processor, an average environmental brightness and determining a current pulse width modulation (“PWM”) output level provided to the light source. The method also includes determining, using the electronic processor, a target illumination level and a PWM adjustment rate. The PWM adjustment rate is based at least partially on the calculated average environmental brightness. The method also includes adjusting, using the electronic processor, the current PWM output level at the determined PWM adjustment rate to reach the target illumination level, and transmitting the adjusted PWM output level to the light source. The target illumination level is determined as a function of the current PWM output level and an output mode of the light source.

Abstract: A method of predicting a central fishing ground of flying squid family Ommastrephidae, includes three steps of setting spatial and temporal dimension, setting environmental factor, and establishing a central fishing ground prediction model. The spatial and temporal dimension includes three levels of spatial dimensions, and two levels of temporal dimensions of week and month. An SST is selected as a main environmental factor, and two environmental factors, i.e., SSH and Chl-a, are selected as a supplement. The environmental factors include four situations. According to the setting situations of the spatial and temporal dimension and the environmental factor, a set of sample schemes of 24 situations is established using permutation and combination method. An error backward propagation neural network model is established, wherein an input layer inputs data of the sample scheme set, and an output layer outputs a CPUE or a fishing ground grading index converted from the CPUE.
