This article discusses an adaptive cruise control system aimed at monitoring the distance with the vehicle ahead. This system allows for the automatic control of the throttle by electronic control signals instead of manual pedal operation. In the research, a predictive control model (MPC) is utilized within the Matlab/Simulink software to simulate the control process of the research model.

The literary text is the communication between the author and the reader. When the author uses the discourse to actualize the experiences of what is happening around or inside them. Descriptive discourse is the flexible discourse genre, the multifunctional social entity. In discourse research, the “dynamic” not only are personal thoughts and attitudes realized, but the moral standards and social ideologies of the community are also clearly realized.

This paper introduces a practical and simple power control method for wind energy conversion systems based on a doubly-fed induction generator. Due to the limitations of traditional proportional-integral controllers when the parameters of the doubly-fed induction generator and wind speed vary, fuzzy control theory is applied to overcome these challenges.

This research aims to enhance comprehension of legal texts by applying Talmy's (2017) threestep process for identifying and integrating referents from contextual cues into linguistic forms. Drawing on pragmatics, discourse analysis, cognitive semantics, and Talmy's force dynamics notion, a qualitative content analysis investigates the cognitive processes readers use for cue detection, attention allocation, and semantic integration when reading court indictments.
