First, when Wji(m) and δjOi assume the same numerical sign, meaning that there may exist a large distance between the current weight vector position and the forthcoming minimum point, the weights adjustment is thus increased. Therefore, the inclusion of the momentum coefficient here acts as ...
To calculate the VaR for a single asset, we would calculate the standard deviation of its returns, using either its historical volatility or implied volatility. If a 95% confidence level is required, meaning we wish to have 5% of the observations in the left-hand tail of the normal distribut...
1, the essence of the balance coefficient In order to discuss the essence of the balance coefficient, we must start with the principle of the traction elevator. A vertical lift is a lifting device for vertical and downward movements of heavy objects. From the angle of mechanics, to make a ...
1. Explain the meaning of the coefficient of linear expansion for a material. 2. How is \Delta L related to \Delta T? 3. Will \Delta L be the same regardless if the rod is hollow or solid? Derive an equation for the equivalent stiffness...

First, we have compared the data pretreatment methods, to select a suitable one for the rest of the analyses. The effect of pretreatment was significant according to ANOVA, meaning that the results were significantly different for the different scaling options, as seen in Fig. 4. For the furth...
Figure 2f plots the wavelength dependence of the photocurrent for devices with lateral pads patterned with a finger-like design (as in Fig. 1c) with different pitches. The fill ratio (i.e., Au finger area per total available pad area) is kept constant at 0.5, meaning that, e.g., ...
An overview of modeling and experiments of vortex-induced vibration of circular cylinders In considering the transverse force on the cylinder, the lift coefficient CL is expressed in terms of an in-phase inertia force and an out-of-phase drag force. The inertia coefficient Cml characterizes the ...
