The auxiliary parts of the impact test hammer are only suitable for certain cases. The impact velocity of other cases are determined by measuring. Instead of measuring multiple times, the hammer velocity calculating method and program is suggested by this article for general cases and the input parameters will be changed for the other cases. The calculation results are verified by using a high speed camera to measure the hammer velocity.

Mathematical model of reaction systems contains experimental parameters such as reaction enthalpies, which may be inaccurate and, therefore, severely affect the computation as well as the implementation of feedback control laws. This paper aims to design an adaptive PI-like controller to regulate a chemical reaction system by means of the Lyapunov theory.

The main objective of this paper is to categorize the available literature (analytical/experimental). The discussion remains descriptive, and the reader is recommended to consult the cited references for specifics on parameters and mathematical models. Three phases were adopted to conduct this literature review: (a) conducting the review, (b) conducting the analysis, and (c) writing up the review.

Time series analysis is an essential field in data analysis, particularly within forecasting and prediction domains. Researching and building time series models play a crucial role in understanding and predicting the temporal dynamics of various phenomena. In mathematics, time series data is defined as data points indexed in chronological order and have a consistent time interval between consecutive observations.
