The focus is on fundamental and advance papers that understanding of applied scientific research. JOAASR incorporates innovations of the novel theoretical and experimental approaches on the quantitative, qualitative and modeling of advanced scientific concepts.</p> http://mail.joaasr.com/index.php/joaasr/article/view/748 Optimizing Performance of Cloud Infrastructure Through Effective Resource Scheduling 2023-11-04T13:10:32+00:00 M.Abdullah abdulcs1963@gmail.com Dr. M. Mohamed Surputheen msurfudeen@yahoo.com <p>Cloud computing has emerged as a very promising technology that has garnered significant interest from both industry professionals and academic researchers. Cloud computing service models refer to the various types of services that are provided, including hardware and software infrastructure, platforms for application development, testing, and deployment, as well as enterprise software that is readily available for usage through subscription. Public cloud computing involves the delegation of IT infrastructure, storage, or applications to an external service provider. The presence of a cloud infrastructure also signifies the existence of geographically distributed computing resources. The utilisation of resources in conjunction with cloud computing is not exclusive to large-scale organisations, as it may be employed by entities of any size. Numerous services are offered based on a fee-for-use model, rendering them cost-effective for organisations of various sizes. Cloud service providers are obligated to provide consumers with cloud services on demand, as there is a growing need for such services. This requirement stems from the necessity to decrease the size of large data volumes, which in turn leads to cost savings in maintaining extensive storage systems. The overall effectiveness of cloud computing environments is directly related to the operational performance of cloud infrastructure. This phenomenon holds substantial significance in the realm of optimization, since it enhances the overall efficiency of the underlying cloud architecture. The proposed technique exhibits a significant effectiveness in enhancing cloud performance, as it manifests improvements for both service providers and cloud customers.</p> <p><strong>Key Words: </strong>Cloud Computing, Task Scheduling, Cloud Infrastructure, Resource Scheduling, Performance Analysis and Infrastructure as Service.</p> 2024-02-26T00:00:00+00:00 Copyright (c) 2024 JOURNAL OF ADVANCED APPLIED SCIENTIFIC RESEARCH http://mail.joaasr.com/index.php/joaasr/article/view/797 Detection and Removal of Assymmetrical Skin Lesions Using DU-Net for Patch Extraction 2023-12-19T14:07:04+00:00 Gopikha S gopikha.in@gmail.com BalaMurugan M mbala@bdu.ac.in <p id="E253" class="x-scope qowt-word-para-2"><span id="E255" class="qowt-font2-TimesNewRoman">The incidence of melanoma, a highly </span><span id="E256" class="qowt-font2-TimesNewRoman">fatal</span><span id="E257" class="qowt-font2-TimesNewRoman"> kind of malignant </span><span id="E258" class="qowt-font2-TimesNewRoman">tumor</span><span id="E259" class="qowt-font2-TimesNewRoman">, is exhibiting an upward trend in its progression.

The DU</span><span id="E267" class="qowt-font2-TimesNewRoman">-net framework incorporates deep convolutional neural networks, notably YOLOv5, to perform patch detection.
