The escalating research focus on natural plant-based fibers has been attributed to their cost-effectiveness, lightweight nature, and minimal carbon footprint in contrast to engineered fibers such as glass, steel and polymer fibers.
In addition, the inherent self-curing mechanism of natural fibers enhances the concrete performance, rendering them a highly promising substitute to engineered fibers [17–19].
Consequently, the key findings of this research can be leveraged by engineers and architects to identify the most suitable concrete candidate, Typha percentage, sand and cement mixtures for new concrete designs.

Introduction The study of oceans needs underwater vehicles such as AUVs and ASVs with concrete aims to enhance the effectiveness of civil society in economic as well as in other naval facilities, e.g. the biological discovery of ocean resources, disaster and tsunami warnings, self-operated underwater military means, etc.
AUV/ASV Dynamics and Control Structure AUV/ASV Dynamic Model According to the Society of Naval Architects and Marine Engineers (SNAME) [8], the six motion components of an underwater vehicle are defined as surge, sway, heave, roll, pitch, and yaw, which are presented in Fig. 1.
No single formalism or language of an engineering process can possible capture all the knowledge and information needed to solve complex control systems such as the AUV/ASV’s controller.

Thermal Degradation of Natural Rubber Vulcanizates Reinforced with Organomodified Kaolin Intercalates CHINEDUM Ogonna Mgbemena1,a*, IKUOBASE Emovon1,b 1Department of Mechanical Engineering, Federal University of Petroleum Resources, Effurun, Delta State, Nigeria a*mgbemena.ogonna@fupre.edu.ng, bemovon.ikuobase@fupre.edu.ng Keywords: Kaolin, Natural Rubber, Rubber Seed Oil, Tea Seed Oil, Thermal behaviour, Vulcanizates.
It has been established and reported that Natural Rubber without fillers have no strength and cannot be utilised in key engineering applications [4,5].
Classic examples of fillers include Calcium carbonate, talc, carbon black, kaolin, precipitated silicas and silicates[6–11] Natural Rubber vulcanizates (NRV) have numerous industrial applications in automobiles, aerospace, industrial machinery, electrical engineering, civil engineering and packaging.
This present study will enable engineers and materials scientists to understand the thermal degradation of NRV and decide suitable applications of the vulcanizates. 2.
