EVENT TRIGGERED PRESCRIBED TIME TRAJECTORY TRACKING CONTROL FOR UNMANNED SURFACE VESSELS WITH LUMPED DISTURBANCES AND PRESCRIBED PERFORMANCE CONSTRAINTS

Abstract This article proposes a prescribed-time trajectory tracking control algorithm for unmanned surface vessels with lumped disturbances, limited communication, and error constraints, utilizing an event-triggered mechanism.Firstly, we present a prescribed-time lumped disturbances observer to accurately estimate the lumped disturbances, includin

One of the results of the expansion using land transportation means in various aspects of life was the emergence of many problems with economic, security, health and social aspects.Perhaps the most prominent embodiment of this is the escalation of the number of deaths and injuries of car accidents and the resulting priceless human losses with the a

The DEP1 (dense and erect panicle 1) gene, which corresponds to the erect panicle architecture, shows a pleiotropic effect in increasing Lego Boxed grain yield and nitrogen use efficiency (NUE) in rice.Nevertheless, it remains unclear whether the carbon-nitrogen metabolic balance changes as the dep1 allele enhances nitrogen uptake and assimilation.

Additive manufacturing, particularly the laser powder bed fusion (LPBF) technique, has ushered in a new era of intricate metallic component fabrication, leveraging the exceptional performance of the Ti6Al4V alloy.However, the intricate mechanical behavior of additively manufactured Ti6Al4V, particularly its anisotropic attributes stemming from non-

Soybean mosaic virus (SMV), a member of Potyvirus, is the most destructive and QUERCETIN LIPOMICEL widespread viral disease in soybean production.Our earlier studies identified a soybean 40S ribosomal protein S8 (GmRPS8) using the 6K1 protein of SMV as the bait to screen a soybean cDNA library.The present study aims to identify the interactions bet
