Abstract: Our suggested self-driving car concept is a more cost-effective and simplified version of the real thing. Students' comprehension of how a real autonomous automobile operates will be aided by this model. Some difficulties in the real world can also be solved with the aid of this paradigm. Other vehicles, such wheelchairs, can be made autonomous and capable of being operated by the user without assistance by applying the same logic and algorithm employed in this model. There is also a description of the hardware architecture, which can be adjusted as needed.

Abstract: For commuters in these cities, traffic congestion is a nightmare come true and a huge issue in numerous large cities worldwide. At a number of significant crossroads, traffic can be managed by implementing traffic police or automated traffic signal management. Nevertheless, the foundation of conventional traffic signal systems is the idea of set times on either side of an intersection, which are immutable with respect to traffic volume. Because increased......

Abstract: Optical Fiber Communication (OFC) revolutionizes modern telecommunications, enabling rapid data transfer across long distances with minimal signal loss. This comprehensive review explores OFC's historical evolution, core principles, components, and versatile applications. It traces OFC's development into a global communication backbone and elucidates key principles like total internal reflection, modal dispersion, and attenuation governing light propagation. The paper details OFC system components such as light sources, fibers, connectors, amplifiers, and detectors. It also examines modulation formats and multiplexing techniques like AM, FM, TDM, and WDM for data transmission. Recent advancements including coherent detection, optical amplification, and fiber-optic sensing are discussed, along with their impact on future networks......

Abstract: This paper presents a novel method for enhancing images captured in low-light conditions. The proposed approach utilizes a combination of noise reduction techniques, image fusion, and contrast enhancement to produce high-quality images with improved visibility and detail. Unlike existing methods, our approach is flexible and adaptable, allowing users to adjust the level of enhancement based on their specific requirements. Experimental results demonstrate the effectiveness of the proposed method in improving image quality in various low-light scenarios..

Abstract: In our contemporary era, a noticeable shift towards electric vehicles is taking place, driven by the urgent need to curb pollution originating from conventional fossil fuel automobiles and to offer a viable solution to the escalating costs of transportation. Nowadays, the convenience of electric vehicles extends beyond mere functionality; with designated charging stations or the ease of home charging, refuelling becomes an effortless part of daily life. The concept of wireless transmission, already familiar in the realms of data, sound, and video signals, now extends to the transfer of power without physical connections. Credit for pioneering wireless power transfer goes to the visionary......
