This research article proposes an automatic frame work for detecting COVID -19 at the early stage using chest X-ray image. It is an undeniable fact that coronovirus is a serious disease but the early detection of the virus present in human bodies can save lives. In recent times, there are somany research solutions that have been presented for early detection, but there is still a lack in need of right and even rich technology for its early detection. The proposed deep learning model analysis the pixels of every image and adjudges the presence of virus. The classifier is designed in such a way so that, it automatically detects the virus present in lungs using chest image. This approach uses an image texture analysis technique called granulometric mathematical model. Selected features are heuristically processed for optimization using novel multi scaling deep learning called light weight residual-atrous spatial pyramid pooling (LightRES-ASPP-Unet) Unet model. The proposed deep LightRES-ASPPUnet technique has a higher level of contracting solution by extracting major level of image features. Moreover, the corona virus has been detected using high resolution output. In the framework, atrous spatial pyramid pooling (ASPP) method is employed at its bottom level for incorporating the deep multi scale features in to the discriminative mode. The architectural working starts from the selecting the features from the image using granulometric mathematical model and the selected features are optimized using LightRESASPP- Unet. ASPP in the analysis of images has performed better than the existing Unet model. The proposed algorithm has achieved 99.6% of accuracy in detecting the virus at its early stage. © 2022 Tech Science Press. All rights reserved.

Concrete Paver blocks are ideal materials for footpaths, parking areas for easy placing, aesthetic look and finish. It was found that rapid failure occurred on pavers and blocks became unusable within few years of its utility. The application of paver blocks has extended to the traffic areas and due to movement of vehicles, the formation of cracks on the paver blocks. An attempt is made by partially replacing cement with Rice Straw Ash (RSA) in paver blocks. Rice Straw ash is one of the agriculture waste materials that create most of the environmental conflicts. These conflicts are on the rise over the world, posing a serious threat to human health. The aim of this research is utilization of RSA as cement replacement material in concrete for making paver blocks. RSA increases the compressive strength, flexural strength, decrease water permeability and workability of the concrete. Partial replacement of cement in different percentage as like 0%, 5%, 10%, 15% and 20% has been done. The strength properties have been determined at the end of 7 and 28 days of curing. The durability properties such as sulphate resistance, acid resistance, salt resistance tests have been conducted at 90 days immersion in the solutions.

Acoustic Voice Quality Index is a six-variable acoustic model for the multiparametric measurement developed by Maryn et al. Studies have provided evidence regarding the practical usefullness, internal consistency, external validity, diagnostic accuracy, and responsiveness to change of AVQI. Recently, researchers have been exploring the utility of AVQI in classifying the voice severity. The aim of the present study was to determine the diagnostic accuracy of the AVQI v.02.03 in discriminating across the perceptual levels of dysphonia severity in 18-40 years age range in Kannada speaking population; and to develop an application to depict the AVQI based severity of dysphonia. For the study, 163 individuals in normophonic and 134 individuals in dysphonic group were considered in the age range of 18-40 years. All participants were native speakers of Kannada language. The sustained vowel /a/ and reading of standard Kannada passage were considered as stimuli for extracting AVQI analysed using AVQI script version 02.03. The AVQI cut-off values obtained were 2.50 (A

Large cardamom (Amomum subulatum Roxb.) is one of the important cash crops of Sikkim and Darjeeling areas of West Bengal. In this study, a fixed plot survey on insect pests of large cardamom was conducted and found that stem borer (Glyphipterix spp., Lepidoptera: Glyphiperidae), shoot fly (Merochlotops dimorphus Cherian, Diptera: Chlororpidae), leaf eating caterpillar (Artona chorista Jordon, Lepidoptera: Zygaenidae) and tea mosquito bug (Helopeltis theivora Waterhouse, Hemiptera: Miridae) are the major pests of the crop. Eco-friendly organic treatments like neem-based oil, petroleum-derived horticultural oil, spinosad and different formulations of entomopathogens were tested against these major insects. Among all, application of spinosad 45 SC @ 0.3 ml L-1 was found effective followed by neem-based oil (Azadirachtin 0.15% EC) 1500 ppm @ 3 ml L-1 at three different time intervals (first application in February-March, second application in June-July and third application in October-November) against all insects. Moreover, entomopathogenic bio-control agents (Bacillus thuringiensis @ 2 ml L-1, Metarhizium anisopliae@ 5 ml L-1 and Beauveria bassiana @ 5 ml L-1) were on par with neem-based oil for the management of stem borer. Considering the economic importance of the crop and absence of valid technology for management of insect pests in large cardamom through organic options, application of either of them could be helpful in organic management of insect pests in Sikkim.

Due to the huge flow of data and complications in mutable characteristics of the data, Distributed Denial of Services attacks existed in the Multimedia Internet of Things. Attacks over the IoT have become an increasing menace in recent time, which tries to hack or illegally tamper the streaming data available over the networks. On the other hand, there has been an increase in volume in research contributions to effectively counter these attacks and implement a strong defense mechanism. There have been numerous algorithms and frameworks implemented in recent times that are intelligent and soft computing-based. These evolution-based algorithms play a vital role in self-adapting the system under attack towards increasing and new types of attacks which are increasing day by day. One such area of soft computing algorithms investigated in this paper is the Artificial Neural Network or popularly known as ANNs. It works analogously to the biological neurons in the human body. In this paper, we systematically explain the ANN-based network model to counteract the DDoS attacks in the Multimedia Internet of Things, architecture, and implementation of ANNs, the experimental investigations and findings which help in drawing an inference of ANN-based defense models.

The mobile users have acquired the benefits of cloud computing with the help of Mobile Edge Computing (MEC) technology in order to satisfy the increasing data demands. The efficiency of the system is highly limited by the bandwidth limitations and limitations associated with the mobile devices despite the rapid development of MEC as well as the cloud computing technology. Our aim is to provide an optimal method to optimize the energy consumption in the mobile edge computing. In this regard, the research paper proposed a Green Cloud based Queue Management system for 5G networks that helps in addressing the issues related to latency and energy consumption. While serving the users, the proposed methodology results in less amount of energy being wasted and hence the reduced latency. By means of alleviating the congestion and implementing the virtual list, this issue can be resolved greatly. Simulation is done with the help of NS2 green cloud simulator and the results are obtained by comparing the proposed model to conventional cloud model and cloudlet based on throughput, latency, energy consumption and normalized overhead as these are the evaluation measures. The results show that there has been considerable enhancement in the energy consumption. As the throughput increases, the quality of the service also increases.

Ring spot caused by Leptosphaeria sacchari is a very common disease of sugarcane in humid tropical conditions. We have conducted a detailed study on status of disease resistance to the disease in our major Saccharum spp collections of Saccharum officinarum. All the S. officinarum clones exhibited ring spot disease with varying intensity as 70.14% clones showed resistant reaction, 24.3% clones showed intermediate reaction and 5.5% clones showed susceptible reaction. The disease appears in the month of June and remains until the harvest. Maximum average disease severity (29.33%) was observed in the July. The accessions analysed also showed significant difference with respect to origin. Multiple comparisons indicated that mean rank of Thailand accessions (682.50) was significantly highest as compared to those of other. Stalk height and leaf length showed significantly weak correlation with ring spot incidence, and other morphological factors were not significant. Disease severity with leaf colour and canopy type was found significant. Purple-leaved clones recorded lower disease incidence than other clones. Very strong positive correlation was observed with rainfall, evening relative humidity and rainy days, whereas maximum temperature showed significant negative correlation. This study clearly indicated the role played by the morphological factors, juice quality traits and weather factors in determining resistance in germplasm to ring spot disease in sugarcane.

The main objective of this study was to investigate the flexural behavior of self compacting self curing concrete (SCSCC) beams using lightweight expanded clay aggregates (LECA) and fly ash aggregates (FAA). The light weight aggregates used in this experimental investigation are high porous and water absorption capacity; so that the water required for self curing is taken from the water which is held in the internal pores of the aggregates. Self curing by the addition of lightweight fine aggregate under saturated surface dry (SSD) condition enhances the strength & durability of the concrete and it maintains saturated condition with in the hydrating cement paste. The fine aggregate was replaced by LECA/FAA by 0% to 20% at 5% interval in volume basis. The flexural behavior of self compacting self curing concrete in hardened state was carried to assess the feasibility of the study. The reinforced concrete beams of effective size 1200 mm x120 mm x180 mm and reinforced with High Yield Strength Deformed (HYSD) bars are casted and tests were performed in loading frame. The load deflection behavior, moment carrying capacity and ductility ratio of beams are found and the test results indicate that the 15% replacement of fine aggregate by LECA/FAA achieved higher moment carrying capacity and ductility ratio.

Tungsten Inert Gas (TIG) Welding is a type of arc welding process which has its major application in the pressure equipment industries. The shielding gas used in TIG welding avoids the contamination of weld and it also enhances the weld characteristics. Normally, the inert gases are used as shielding gas. The aim of this study is to investigate the weld characteristics of alloy steels with pure argon and argon (80%) mixed with carbon dioxide as shielding gas. During the study, the weld penetration and the number of root passes were monitored. Then the weld characteristics were analyzed by mechanical testing of the welded specimen were examined. Finally, a thorough technical comparison is made for the different shielding gases in detail.

Thermal spray coating is a surface modification technique that improves the properties of the metal surface. The basic principle of this technique is the combination of melting and acceleration. Thermal spray coatings are also classified as plasma spray, High-Velocity Oxy-Fuel, wire arc, detonation, and so on. Among the types of thermal spraying, the high-velocity Oxy-fuel process is a widely used technique in various applications. Chromium and tungsten carbide are used in down-hole drilling tools and gas turbine engines because of high resistance to wear, erosion, cavitation, high hardness, and toughness. In this review article, wear characteristics, corrosion analysis, hardness, surface roughness, and microstructure of thermal sprayed High-Velocity Oxy-Fuel - Tungsten Carbide coatings have been addressed.

This current study intends to measure the durability of self compacting concrete with lightweight aggregates. Saturated scoria and fly ash aggregate (FAA) is used as self curing agents in self-compacting concrete (SCC). Scoria and FAA were pre sopping for 24 h before concreting. Fine aggregate was replaced by Scoria and FAA by volume. Scoria content was varied from 5% to 20% at an increment of 5% and FAA is fixed at 15%. A total of 7 mixes were studied including the direct mix. Both presaturated scoria and FAA detains the water in its pore structure and supplied the water required for internal curing. The durability properties such as salt attack, volume change and ultra sonic pulse velocity (UPV) test were carried out at the age of 7, 28, 56 and 90 day on hardened concrete. This experiments responses shows that the replacement of fine aggregate by presaturated Scoria and FAA sustained the strength and durability of the concrete.

The strength gaining process is essential in case of conventional concrete structures, to achieve desired properties. To achieve target strength concrete, it’s required 28 days of curing and proper hydration. Improper curing can lead to badly effects in strength and lastingness point of view. Self-curing is modern technique to cure concrete, which due to moisture content cured itself in it. The admixture helps to take good hydration while using of polymer is polyethylene glycol in conventional concrete and useful to create agents of emulsified, plasticizers, detergents, and lubricants of textile in water soluble. In the present investigation Polyethylene glycol-600 admixture in concrete would results in the strength increases compared to conventional curing. The admixture of Polyethylene Glycol-600 on weight of cement 0.3%, 0.6%, 1%, 2% was studied. The test result showing that the use of polymer in water soluble has upgrade presentation of concrete and increase of strength criteria.

It has been said that “Many buildings have been damaged or demolished by earthquakes in India, not killing people, but losing precious lives”. The ability of structures to resist a major earthquake is significantly enhanced by observing how buildings acknowledge to the earthquake and utilising the expertise obtained by engineers. During the design of a perfect structure many challenging areas need to be addressed and when the structures are to be constructed in earthquake-prone areas, those difficulties are compounded. The main intension and purpose of this paper is to design an earthquake resistant structure by undertaking seismic study of the structure by static equivalent method of analysis and execute the design of structure using STAAD.pro software. For this present research work, a G + 5 residential building is considered. Seismic calculations are executed for all the earthquake zones.
