The above research work offers ways of an accident prevention system employing an eye blink sensor as well as an automated braking technique to make sure that when fatigue is detected and the driver doesn't respond to the buzzer's warning bell within the permitted time, the Vehicle comes to a slow stop. During the allocated time before circuit design, the vehicle's hazard, warning lights are turned on to warn other drivers, particularly those driving ahead. Thus, the results show that the eye blink sensor is used by the car's accident prevention system once the car has stopped. The Proteus software package and the C++ programming language were utilized to verify that the automated braking system is an effective method for reducing accidents caused by fatigued driving. The design and development of a car collision and accident prevention system, when drowsiness is identified using eye blink sensors is proposed in this research paper. This research work is essential because incorporating this technology into automobiles prevents accidents caused by driving when fatigued. This research work might be improved by more research to increase driver attention by employing wireless technology to inform other cars when the driver is tired rather than using the vehicle's danger warning lights","PeriodicalId":16654,"journal":{"name":"Journal of Nano-and electronic Physics","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68046208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Macroporous silicon and silicon structured by nanowires are considered as a two-layer structure of silicon with an effective medium. The analytical model of the reflection from a two-layer silicon structure with an effective medium takes into account the absorption of light by the structure and the multiple reflections of light from the surfaces of the sample and the interface between the effective medium and the monocrystalline substrate. The reflection coefficient from a structured surface, which is the boundary between two media, contains the complex index of refraction of silicon. The effective index of refraction of the effective medium is found from the expression for mixing two media. The reflection of light falling on flat surfaces at different angles is calculated according to Fresnel's formulas. The frontal structured surface and the second structured surface were considered as Lambert surfaces. Total internal reflection from a flat surface between silicon and air is given by Snelius' law, and from structured surfaces between silicon and the effective medium and between the effective medium and air is accounted for by co-efficients. The reflection spectra from macroporous silicon and arrays of silicon nanowires on a monocrys-talline substrate are calculated according to analytically derived formulas. It is shown that the magnitude of reflection spectra from macroporous silicon and arrays of silicon nanowires on a monocrystalline substrate decreases when the volume fraction of pores increases. The reflectance begins to increase again when the pore volume fraction is high. Reflection from the surface between the effective medium and air is observed at a high volume fraction of pores.","PeriodicalId":16654,"journal":{"name":"Journal of Nano-and electronic Physics","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68046477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The NWMCFET is created by splitting the Nanowire MCFET into four channels, and the charge plasma concept is employed during the design process using the Sentaurus TCAD simulation tool. To enhance the performance of the NWMCFET, Silicon Carbide (SiC) is utilized for the source and drain regions. The integration of SiC, combined with the utilization of a multi-bridge channel and the device's Ultra-Thin Body (UTB) technology, leads to an increased current drive capability. The Cur-rent-Voltage ( I-V ) characteristics of the device are plotted, and it is observed that these techniques result in a notable enhancement in current drive and overall performance. Additionally, the inclusion of hetero junction phenomena in the NWMCFET design further improves its performance. Consequently, the device incorporating the multi-channel and electrostatic doping idea demonstrates comparable results to manually doped devices. This finding highlights the potential of the proposed device design. Particularly, in the context of sub-10 nm devices, further development in this direction holds significant advantages. In summary, this paper presents a comprehensive exploration of a Nano Wire Multi Channel Field Effect Transistor design, utilizing the charge plasma concept, SiC material, and a multi-bridge channel configuration. The experimental results indicate improved current drive and overall device performance. Furthermore, the incorporation of hetero junction phenomena is found to be beneficial.

The entering plane wave will either be transmitted (passband) or reflected back (stopband) depending on the characteristics of the unit cell. This happens when the frequency of an electromagnetic (EM) wave coincides with the resonance frequency of the FSS components. As a result, an FSS is a spatial filter capable of allowing or inhibiting EM waves of a certain frequency range in free space. FSSs have now been widely investigated, and great progress is being made in the field of their design and implementation for a wide range of practical applications, from microwave to optical frequencies. The Frequency Selective Surface attached to the new center-fed circular patch antenna is presented. A wide band from 5 GHz to 6.2 GHz is achieved with a monopole-like radiation pattern. According to simulation results of the proposed antenna structure, it can be applied in ISM band applications, wireless audio and video systems and other wireless communications at 5.8 GHz. It has a simulated maximum gain of 5.36 dBi and a bandwidth of 31.1 %. Throughout the operational band, the omnidirectional radiation pattern is fairly constant. The overall dimensions of the antenna are 27.34  27.34 mm 2 including FSS structure thus makes a compactable wideband system at 5.8 GHz. A circular patch antenna with diamond slot at center initialize first resonance at 5.8 GHz with a dimension of 20  20 mm 2 and performance parameter is further improved by appending FSS Structure.","PeriodicalId":16654,"journal":{"name":"Journal of Nano-and electronic Physics","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135699625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
