Wireless Mesh Networks (WMNs) are susceptible to various security threats, including black hole attacks, where malicious nodes attract and drop packets, disrupting network communication. Traditional mechanisms often inadequate in detecting mitigating these attacks due their dynamic evolving nature. In this paper, we propose a novel deep learning-based defense mechanism against WMNs. It utilizes Recurrent Neural (RNNs) Long Short-Term Memory (LSTM) networks analyze traffic patterns detect...
Performance of a polymer electrolyte membrane fuel cell is appreciably improved by flow-field geometry. In recent literature, it has been observed that naturally inspired flow channel designs enhance the fuel-cell performance. The relevant examples are plant leaves and human lung structure. high performance these uniform reactant distribution better water management. this study, geometry bipolar plate used in for supply reactants. A 49 cm2 area with Nafion-117 assembled incorporating tested...
Fuel cells technologies are the most promising green energy for diverse applications. One of fastest growing areas is portable electronic applications where power range order 1–100 W. For devices, rechargeable battery major source. Due to limitations like limited capacity, requirement external recharge have led many researchers look alternative sources devices. The high density fuel makes them very attractive batteries There a variety cell being considered replace in equipment. Direct Liquid...
This study investigates the influence of void microstructure on effective elastic properties high fiber volume fraction discontinuous fiber-reinforced composites with randomly oriented fibers. A is characterized by using parameters such as number voids, fraction, Aspect Ratio and size distribution. In order to overcome difficulties associated creation representative element models containing a novel automation program called “ArtiComp” developed. used generate straight fibers, curved fibers...
Liquid feed Passive Direct Methanol Fuel Cell (DMFC) is a promising option for charging low power application devices. In passive DMFC, Nafion membranes provide high proton conductivity, chemical, and thermal stability. However, the DMFC suffers from disadvantage that membrane allows flow of methanol fuel anode side to cathode (methanol crossover), leads mixed overpotential losses. present study, liquid electrolyte (LE) layer introduced between two reduce crossover improve performance DMFC....
A fuel cell hybrid (FCH) mid-size car is modeled and simulated in Advanced Vehicle Simulator (ADVISOR), the results are compared with 2017 Toyota Mirai Fuel Cell Electric (FCEV) to examine capability of hybridization compare economy vehicle. The aim this analysis understand energy interactions batteries identify an optimal management. In current modeling, power downsized by 30% a corresponding increase number battery modules 50% compensate maintaining same motor demand. Urban Dynamometer...
Abstract Development of possible technologies for the generation green energy is focus research worldwide. Fuel cells are a promising option in this regard. Out various categories fuel cells, air breathing–direct methanol (AB‐DMFCs) finding prominent place as an electric power source charging compact electronic devices. In AB‐DMFC, design and construction cathode current collector very crucial, since performs important functions cell operation such collecting electrons, facilitating flow...
A 3-D PEM fuel cell model with 3-pass serpentine flow field was developed to analyse the performance of cell. Simulations were carried out in commercial ANSYS FLUENT 15.0 software species concentration on anode side as H2 – 0.8, O2 0, H2O 0.2 and cathode 0.2, 0.1. Along cell, key parameters like pressure drop, hydrogen mass fraction, oxygen liquid water activity membrane content have been analysed. The results showed that when operated at a lower voltage 0.4 V, i.e. higher current density,...
Achieving the new emission norms is a difficult task to today’s compression ignition (CI) engine without any exhaust gas after-treatment technologies. It necessary find practical method which reduces unsafe emission, with minor modifications of CI engine. Dual fuel homogeneous charge (HCCI) has been recognised as one solutions minimise emissions and achieve higher performance. In present study dual HCCI mode operation carried out by supply ethanol fuel-air mixture cylinder through carburetor...
Water and CO2 are by-products of an active direct methanol fuel cell (ADMFC) during its operation. In the present study, ADMFC is operated with air-breathing technique. A cathode open to atmosphere anode side solution pumped using a peristaltic pump. polytetrafluoroethylene-coated carbon porous layer added in between flow field plate current collector at determine performance experimentally. series experiments were conducted for different thicknesses ranging from 0.1 0.3 mm reactant mass...
