Surface Charges Guided Quasi‐TEM‐mode Microwave Propagation along Dielectric Nanowire

open access: yesAdvanced Physics Research, EarlyView.
According to Maxwell's equations, a single‐conductor transmission line cannot allow TEM‐mode electromagnetic wave propagation, however, this is based upon the assumption that dielectric material is isolated from the environment. In practice, surface electrostatic charges widely existed in nano‐materials with large surface‐to‐volume ratio.

Modeling of inflation cases in South Sulawesi Province using single exponential smoothing and double exponential smoothing methods [PDF]

open access: yesQuality and Quantity, 2021
The inflation rate, particularly in South Sulawesi Province from year to year, is found to be very unstable, so that an effort to overcome the instability of the inflation rate is highly needed. One of the efforts that can be used is to carry out a process of forecasting the inflation rate, so that the government can predict the inflation rate properly

Forecasting by fuzzy double exponential smoothing model

International Journal of Computer Mathematics, 2003
The exponential smoothing model is a popular tool in short-term forecasting. However, the smoothing constant is arbitrary and is determined by a decision maker in both the nature and perception of the unknown system structure to make the forecasting of exponential smoothing model ineffective.
