Internet of things (IoT) has been significantly raised owing to thedevelopment of broadband access network, machine learning (ML), big dataanalytics (BDA), cloud computing (CC), and so on. The development of IoTtechnologies has resulted in a massive quantity of data due to the existenceof several people linking through distinct physical components, indicatingthe status of the CC environment. In the IoT, load scheduling is realistictechnique in distinct data center to guarantee the network suitability by fallingthe computer hardware and software catastrophe and with right utilize ofresource. The ideal load balancer improves many factors of Quality of Service(QoS) like resource performance, scalability, response time, error tolerance,and efficiency. The scholar is assumed as load scheduling a vital problem inIoT environment. There are many techniques accessible to load scheduling inIoT environments. With this motivation, this paper presents an improved deerhunting optimization algorithm with Type II fuzzy logic (IDHOA-T2F) modelfor load scheduling in IoT environment. The goal of the IDHOA-T2F is todiminish the energy utilization of integrated circuit of IoT node and enhancethe load scheduling in IoT environments. The IDHOA technique is derivedby integrating the concepts of Nelder Mead (NM) with the DHOA. Theproposed model also synthesized the T2L based on fuzzy logic (FL) systemsto counterbalance the load distribution. The proposed model finds usefulto improve the efficiency of IoT system. For validating the enhanced loadscheduling performance of the IDHOA-T2F technique, a series of simulationstake place to highlight the improved performance. The experimental outcomesdemonstrate the capable outcome of the IDHOA-T2F technique over therecent techniques.

Journal of Harbin Institute of Technology(New series) 2024年

作者： v uma v Ganesh Department of Computer and Information Science Annamalai University Department of Computer Science Government Arts College (Autonomous) Kumbakonam

In recent times， an abrupt upswing has emerged within the data mining domain， particularly within the sphere of sentiment analysis. Encompassing diverse dimensions such as sentiment extraction， subjectivity categorization， opinion summarization， and spam detection， sentiment analysis， also acknowledged as Opinion Mining (OM)， undertakes a mathematical exploration into the perspectives， emotions， evaluations， and conduct of individuals toward entities， encompassing products， services， individuals， and events. The advent of web technology tools empowers users to liberally articulate their opinions across varied online platforms， culminating in the generation of a substantial corpus of invaluable yet unstructured data. This exposition scrutinizes the importance of harnessing this data， delving into the intricate process of refining and metamorphosing it for subsequent operations like classification and aspect-oriented sentiment analysis. The crux of the discourse centers on a thorough scrutiny of four data mining algorithms deployed for prognostication and categorization， providing insights into their efficacy within the domain of sentiment analysis. This investigation transcends into pragmatic applications， challenges encountered in the field， and potential trajectories ahead， culminating in a nuanced comprehension of the dynamic panorama of sentiment analysis and its ramifications.

Deep bed filtration model for cake filtration and erosion

Many phenomena in nature and technology are associated with the filtration of suspensions and colloids in porous media. Two main types of particle deposition,namely, cake filtration at the inlet and deep bed filtration throughout the entire porous medium, are studied by different models. A unified approach for the transport and deposition of particles based on the deep bed filtration model is proposed. A variable suspension flow rate, proportional to the number of free pores at the inlet of the porous medium, is considered. To model cake filtration, this flow rate is introduced into the mass balance equation of deep bed filtration. For the cake filtration without deposit erosion,the suspension flow rate decreases to zero, and the suspension does not penetrate deep into the porous medium. In the case of the cake filtration with erosion, the suspension flow rate is nonzero, and the deposit is distributed throughout the entire porous medium. An exact solution is obtained for a constant filtration function. The method of characteristics is used to construct the asymptotics of the concentration front of suspended and retained particles for a filtration function in a general form. Explicit formulae are obtained for a linear filtration function. The properties of these solutions are studied in detail.

Ion heat transport in electron cyclotron resonance heated L-mode plasma on the T-10 tokamak

引用

Plasma Science and Technology 2024年第4期26卷 52-60页

作者： v.A.KrUPIN M.r.NUrGALIEv A.r.NEMETS I.A.ZEMTSOv S.D.SUNTSOv T.B.MYALTON D.S.SErGEEv N.A.SOLOvEv D.v.SArYCHEv D.v.rYJAKOv S.N.TUGArINOv N.N.NAUMENKO National research Centre“Kurchatov Institute” Moscow 123182Russia Bauman Moscow State Technical University Moscow 105005Russia Institution“Project Center ITEr” Moscow 123098Russia JSC“SOLAr” Minsk 220034Belarus

Anomalous ion heat transport is analyzed in the T-10 tokamak plasma heated with electron cyclotron resonance heating(ECrH) in second-harmonic extra-ordinary mode. Predictive modeling with empirical scaling for Ohmical heat conductivity shows that in ECrH plasmas the calculated ion temperature could be overestimated, so an increase of anomalous ion heat transport is required. To study this effect two scans are presented: over the EC resonance position and over the ECrH power. The EC resonance position varies from the high-field side to the low-field side by variation of the toroidal magnetic field. The scan over the heating power is presented with on-axis and mixed ECrH regimes. Discharges with high anomalous ion heat transport are obtained in all considered regimes. In these discharges the power balance ion heat conductivity exceeds the neoclassical level by up to 10 times. The high ion heat transport regimes are distinguished by three parameters: the ratio Te/Ti, the normalized electron density gradient r/■, and the ion–ion collisionality νii~*. The combination of high Te/Ti, high νii~*, and r/■=6-10 results in values of normalized anomalous ion heat fluxes up to 10 times higher than in the low transport scenario.
