This paper proposes an exactly discretized model for FitzHugh-Nagumo oscillatory system. A recent technique of discretization, Taylor-Lie discretization is used for the exact discretized model. Exact discretization for nonlinear models is new and the proposed model has been compared with canonical discretization technique to establish the quality of Taylor-Lie discretization approach. A set of system theoretic analyses supports the obtained results which includes time response analysis, phase portrait analysis, effects of sampling time T and external stimulus I

This paper provides an overview of the working principle, benefits, and applications of a crankshaft in mechanical systems, particularly in internal combustion engines. A crankshaft is a vital component of a reciprocating engine that converts the linear motion of the pistons into rotary motion, providing the necessary torque to drive the vehicle. This paper explores the various types of crankshafts, including forged steel, cast iron, and lightweight materials such as aluminium and titanium. It examines the advantages and disadvantages of each material, and their suitability for different types of engines and operating conditions. Furthermore, A static stress simulation of torsional load on crankshafts made up of different materials, specifically aluminium, titanium, cast iron, and steel were carried out using varying torques between 250Nm and 850Nm. The stress-load relationships indicated that steel exhibited the lowest stress levels per given load compared to the other materials. This behaviour can be attributed to steel's ability to yield under high forces, making it more resistant to deformation. In contrast, titanium demonstrated a higher tendency to deform under significant loads, while aluminium and cast iron displayed nonlinear strain-stress relationships. However, due to cast iron's brittleness, it is more prone to cracking and failure under severe stress loads. Displacement characteristics of the crankshafts made from different materials were also simulated. Steel exhibited the least displacement compared to aluminium, titanium, and cast iron. This result can be attributed to steel's higher modulus of elasticity, indicating its ability to withstand deformation more effectively. This paper highlights the importance of selecting the appropriate material for a crankshaft to ensure optimal performance, durability, and reliability. It also emphasizes the need to consider the effects of torsional load on crankshafts and the differences between materials in their

This paper presents the design and analysis of a circularly polarized dual-band slotted patch antenna intended for S-band applications using simulation software Advanced Design system (ADS). This design features a circular patch with a crescent-shaped stub. Copper is used for both patch and ground, while FR-4 material is used as substrate. Proposed antenna operates at two resonant frequencies: 2.36 GHz and 2.68 GHz, with effective bandwidth of 2.26–2.44 GHz and 2.66–2.69 GHz, respectively. The designed antenna achieves circular polarization (RHCP) at 2.36 GHz with a reflection coefficient of -47.30 dB and a directivity of 5.85 dBi. Additionally, designed antenna achieves a reflection coefficient of -14.58 dB and directivity of 4.90 dBi at 2.68 GHz. The proposed antenna exhibits an enhanced circular polarization with an axial ratio of 0.43 dB at 2.35 GHz. The Voltage Standing Wave Ratio (VSWR) values of 1.02 at 2.36 GHz and 1.48 at 2.68 GHz demonstrates excellent impedance matching across both frequency bands. The designed antenna highlights promising performance suitable for S-band applications, demonstrating its potential for deployment in wireless communication system.
