In recent times, the utility and privacy are trade-off factors with performance of one factor tends to sacrifice other. Therefore, dataset cannot be published without privacy. It is henceforth crucial maintain an equilibrium between data. this paper, a novel technique on developed, where former developed metaheuristic algorithm latter using cryptographic model. The carried out process clustering, model encrypts decrypts At first, input datasets clustered, after data maintained. simulation...
Currently, electric cars are receiving a lot of attention because their low fuel consumption and pollution-free nature. The efficiency vehicles is constantly being improved via variety studies applications. battery significant portion an vehicle’s overall component count. Because the acts like heart, performance in (EVs) examined this research.
Currently, the growth of tannery industries causes a significant volume waste disposal to environment due harmful Cr(VI). Long-time exposure Cr(VI) imposes serious hazards on all living organisms. Hence, treatment remove is not choice but mandatory. Therefore, this study focused removal from aqueous solutions via teff ( Eragrostis tef) straw based-activated carbon (TSAC) which was derived locally available agricultural solid waste, (TS). The prepared TSAC characterized using BET, FTIR, SEM,...
To develop high quality cookies, even seemingly smallest changes depended on factors that can affect taste, texture, and nutritional value. In this light, study aimed to investigate the upshot of refined wheat flour pumpkin seed properties cookies such as antioxidant activity, thermal oxidative stability. view foregoing, roasted seeds particle size below 500 μm were blended with at different ratios (BR) bake selected pre-determined temperatures (T) time durations (TD). The synergetic effect...
Teff straw ash was first converted into sodium silicate solution, then processed via sol-gel, producing low-density silica aerogel (modified gel). A one-step modification method applied to produce modified gel from teff ash. The involved the use of trimethylchlorosilane (TMCS), ethanol, and n-hexane as reagents, with a specific molar ratio. Then, we used ambient pressure drying complete process. had improved properties compared unmodified one. These chemicals were modify surface substrate....
In the current-generation wireless systems, there is a huge requirement on integrating big data which can able to predict market trends of all application systems. Therefore, proposed method emphasizes integration nanosensors with analysis will be used in healthcare applications. Also, safety precautions are considered when this nanosensor integrated where depth and reflection signals also observed using different time samples. addition, analyze effect nanosensors, six fundamental scenarios...
Cloud storage provides a potential solution replacing physical disk drives in terms of prominent outsourcing services. A threaten from an untrusted server affects the security and integrity data. However, major problem between data cost communication computation is directly proportional to each other. It hence necessary develop model that trade-off metrics cloud environment. In this paper, we verification mechanism enables utilisation cryptographic with algebraic signature. The utilises...
The global standards in the field of industrial automation are maintained industries by completely digitizing their manufacturing process with industry 4.0 standard. Internet Things (IoT) enables conservation cultural heritage proper assistance on data management collected from sensors. However, energy efficient is required to monitor IoT sensors order deal building a better infrastructure. In this paper, we develop bio-inspired algorithm which can automate entire furnace monitoring and...
With increasing advancements in the field of telecommunication, attainment a higher data transfer rate is essentially greater need to meet high-performance communication. The exploitation fuzzy system wireless telecommunication systems, especially Fifth Generation Mobile Networks (or) 5G networks vital paradigm markets. A comprehensive survey dealt paper, where it initially reviews basic understanding systems over telecommunication. literature studies are collected from various repositories...
The effects of the percentage volume reinforcement, ratio and matrix size particles on wear behavior AA5052/B4C metal composites (MMCs) examine. This research examines a model function developed from an artificial neural network (ANN). bent using powder metallurgy technique to hardness ball-on-disc testing. There are two exemptions such as (1) when reinforcement is less than 8% (2) particle (Rs) (Ms) increases before decreasing. results show that loss decreases with increasing Rs Ms. In...
Silica has shown numerous applications in different fields such as environmental, biomedical, agriculture, and even chemical processing. However, due to high energy-intensive cost-effective issues, researchers show interest replace the conventional methods with biobased environmentally-friendly techniques for biosilica production from renewable biomass sources. Generally, silica is found be available amorphous crystalline structures. For commercial purposes, produced alkyl orthosilicates ore...
Abstract The study was focused on preparing activated carbon from one of the predominant agro-wastes, teff straw (TS), through chemical activation and investigating optimum process condition for removing reactive yellow 145 dye (RY 145) simulated textile effluent oxygen demand (COD) industry effluent. prepared (TSAC) characterized using Fourier transform infrared (FTIR), scanning electron microscopy (SEM), point zero charge (pHpzc), X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET)...
Currently, many scholars are looking for renewable biomass sources the isolation of nanomaterials that have a sustainable property and ecofriendly. Thus, effectively synthesize characterization enset fiber nanocellulose using acid hydrolysis with sonication is focus study. Additionally, process optimization (CNCs) from raw RSM-CCD characterizations obtained CNCs was explored. The quadratic model selected, optimized values yield (77.69%) were acquired to be H2SO4: 51.6 wt. %, reaction...
This study is aimed at utilizing brewery’s spent grain (BSG) byproduct for the synthesis of cellulose nanocrystals (CNCs) using acid hydrolysis and optimizing parameters (hydrolysis time, temperature, liquid-solid ratio, concentration). Alkali bleaching treatment were done to remove hemicellulose lignin from BSG. Optimization process was performed central composite design (CCD) obtain optimum value nanocrystal (CNC) yield. The maximum yield 43.24% obtained conditions 50°C, 51 wt%...
