Abstract: A method for producing an ?-olefin oligomer, the method including subjecting ?-olefin to oligomerization reaction to produce an ?-olefin oligomer mixture, carrying out distillation separation of ?-olefin oligomer having less than n carbon atoms in the mixture to obtain a distillation residue containing ?-olefin oligomer having n or more carbon atoms, and then carrying out a step of removing high molecular weight molecules from the distillation residue.

Abstract: A process for increasing MFR2 of a polyethylene copolymer or an ethylene plastomer or elastomer comprising: (I) extruding a copolymer of polyethylene copolymer having a density of 910 to 970 kg/m3 and an MFR2 of 1 and 100 g/10 min or an ethylene plastomer or elastomer having a density of 855 to 910 kg/m3 and an MFR2 of 0.5 and 100 g/10 min in the presence of 0.1 to 2 wt % of a non-peroxide radical initiator so as to produce a polyethylene copolymer having an MFR2 of 200 g/10 min or more, or an ethylene plastomer or elastomer having a MFR2 of 200 g/10 min or more.

Abstract: The invention proposes a method of calculating aerodynamic derivatives for flight vehicle including the following steps: step 1: simulation and calculation of static aerodynamic coefficients for flight vehicle; step 2: simulate forced harmonic oscillation, specifically: create the harmonic oscillation profile by channels and determine the combined derivative according to the pitch, roll and yaw channels for at least 3 different frequencies; step 3: calculate the aerodynamic derivatives for each channel, specifically: establish a mathematical model describing the forced harmonic oscillations according to the channels, developing an optimal program to minimize the cost function and estimate parameters.

Abstract: A method of detecting a user input includes sensing one or more touch events at a device. In some embodiments, a method includes sensing a first touch event via a first housing of a device. The method also includes generating a first detection signal based on the first touch event. The method also includes sensing a second touch event via a second housing of the device, the second housing conductively isolated from the first housing. The method also includes generating a second detection signal based on the second touch event. The method also includes classifying, based on the first detection signal and the second detection signal, the first touch event as user input. The method also includes identifying one or more actions based on the classification of the first touch event as the user input, the one or more actions associated with the user input.
