The aim is to design an antenna within the K-band with three resonance frequencies at 24, 29, and 34 GHz. The antenna is designed on a volumetric dimension of 11×12.7×1.6 mm3. The substrate used is FR4 (dielectric constant 4.4), having a loss tangent of 0.0022. A microstrip line of width 1 mm for a 50 Ω impedance line is used to match with the load antenna, which has four rectangular connected patches. Patch dimensions come from standard antenna equations and simulation done on Ansys High-Frequency Structure Simulator software. Validation of simulated results is done through measurements on the prototype antenna. A substantial good agreement is found between the simulated and measured results. The gain of the proposed antenna is 6.16 dBi, with return loss being ≤-10 dB. Bandwidths are 1.1 GHz (23.8 - 24.9 GHz), 0.9 GHz (28.6 - 29.5 GHz), and 0.8 GHz (33.7 – 34.5 GHz), respectively. The far-field radiation characteristics of both E-plane and H-plane are also reported. The proposed design is suitable for mm wave applications, including smart vehicles, global positioning systems, radio frequency identifications, etc.","PeriodicalId":16984,"journal":{"name":"JOURNAL OF SCIENTIFIC RESEARCH","volume":"121 5-6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140523325","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}

In the cloud, Load balancing is the most significant issue that includes both hardware and software platforms for the execution of demand of the user request. Furthermore, for handling multiple user requests, load balancing is necessary. Therefore, an efficient load-balancing technique is required to optimize and ensure user satisfaction by utilizing the virtual machine's resources efficiently. A novel Orthogonal Projected Regressive MapReduce Lottery Load Balancing (PORLOB) technique is introduced for resource-efficient task scheduling with minimal Makespan and complexity. In the PORLOB technique, many cloud user requests are transmitted to the cloud server from different locations. The load balancer uses the index table for maintaining the virtual machines. The MapReduce function includes two steps, namely, map and reduce. Based on the resource estimation, the map function performs the regression analysis and provides three resource statuses of the virtual machine: overloaded, less loaded, and balanced. In the reduction phase, the load balancer uses the lottery scheduling technique to balance the workload by migrating the task from an overloaded Virtual Machine to a less-loaded VM.","PeriodicalId":16984,"journal":{"name":"JOURNAL OF SCIENTIFIC RESEARCH","volume":"133 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140523188","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 flow is restricted by the flow between two equidistant upright plates, one moving and the other at rest, and the formation of free convection due to a fixed wall at a time-dependent temperature, while heat flow is constant on the wall moving upwards in its plane. The problem is solved analytically, and the expression for velocity and temperature are derived. The effect of numerous physical parameters on the flow is discussed.

The X-ray diffraction (XRD) patterns reveal that the ZTO films have become polycrystalline as we increase the percentage of tin oxide. The crystallinity of films also increases significantly. The field emission scanning electron microscopy (FESEM) results indicate that the percentage of tin oxide changes the film's morphology. UV visible spectroscopy of the films indicates that the band gap is reduced with the increased percentage of tin oxide in the mixture, and transmittance is also decreased at a higher percentage. The transmittance of the films ranges from 90 to 83 %, while the band gap falls within the range of 3.90 to 3.40 eV.

Phosphate solubilizing bacteria can solubilize this immobilized phosphate. The goal of this study was to use random UV mutagenesis to improve the phosphate solubilizing efficiency of the bacterial strains isolated from agriculture soils of Jaipur, Rajasthan. The phosphate solubilizing capacity was determined using the colorimetric chlorostannous reduced molybdo phosphoric acid blue method. When UV treated for 40, 50, and 60  min. Strain B5 depicted 58.54 %, 133.27 %, and 159.09 % enhanced phosphate solubilization, respectively, in the phylogenetic tree constructed using 16S rRNA gene sequencing, the isolate B5 clustered with Pseudomonas putida strains. Thus wild strains such as Pseudomonas sp. and Bacillus sp. can be mutagenically exploited to avail incapacitated phosphorus in soil.

The synthesized nano ZnO powder was subjected to characterization to know the morphology and physical properties. FTIR analysis was employed for the identification of functional group, X-ray diffraction is to identify the crystalline structure, SEM-EDX analysis is employed to determine the morphological structure and size of the synthesized nanoparticles and elemental confirmation, and TEM is used to determine the particle size and shape of synthesized nanoparticles.
