Abstract The outbreak of the COVID-19 pandemic has made widespread testing a need for controlling the disease. Numerous recent investigations have shown that many people with COVID-19 show no outward signs of illness. As a result, these patients are more likely to unwittingly spread the virus because they will not take a COVID-19 test. In order to get tested, patients will need to travel to a lab, putting others at risk of exposure. Recent studies have shown that people with COVID-19 who are asymptomatic have distinctive coughs and breathing patterns compared to the general population. This prompted the study of cough and breath sounds in COVID-19 patients as a means of differentiating them from those of non-COVID lung infection patients and the general population. In this article, we present a robust, efficient, and extensible method for identifying symptomatic patterns in biological audio signals. Cough digitized audio files are subjected to spectral analysis via a stationary wavelet transform (SWT). The proposed model employs ADASYN technique to handle the class imbalance problem. Also, features like Mel-frequency cepstral coefficients (MFCCs), log frame energies, zero crossing rate (ZCR), and kurtosis are extracted. For classification process, deep belief network (DBN) model is utilized. Finally, mayfly optimization (MFO) algorithm is exploited for optimal hyper-parameter tuning of the DBN model. The experimental validation of the proposed model takes place using open access dataset. Proposed method is compared with other methods in terms accuracy, specificity, sensitivity, F1-Score, precision and recall. The experimental outcomes demonstrated the betterment of the proposed model over other recent state of art approaches.
摘要2019冠状病毒病(COVID-19)大流行的爆发使得广泛检测成为控制疾病的需要。最近的许多调查表明,许多COVID-19患者没有表现出疾病的外在迹象。因此,这些患者更有可能在不知不觉中传播病毒,因为他们不会接受COVID-19检测。为了进行检测,患者需要前往实验室,将其他人置于暴露的风险之中。最近的研究表明,与普通人群相比,无症状的COVID-19患者咳嗽和呼吸模式不同。这促使研究人员对COVID-19患者的咳嗽和呼吸音进行研究,以将其与非COVID-19肺部感染患者和一般人群区分开来。在本文中,我们提出了一种鲁棒、高效和可扩展的方法来识别生物音频信号中的症状模式。通过平稳小波变换(SWT)对数字化音频文件进行频谱分析。该模型采用ADASYN技术来处理类不平衡问题。此外,还提取了mel频率倒谱系数(MFCCs)、对数帧能量、零交叉率(ZCR)和峰度等特征。在分类过程中,采用深度信念网络(DBN)模型。最后,利用蜉蝣优化(MFO)算法对DBN模型进行超参数优化。利用开放获取数据集对所提出的模型进行了实验验证。并在准确度、特异度、灵敏度、F1-Score、精密度、召回率等方面与其他方法进行比较。实验结果表明,所提出的模型优于其他最新的技术方法。

An Energy-Aware Agent-Based Resource Allocation Using Targeted Load Balancer for Improving Quality of Service in Cloud Environment 一种基于能量感知代理的资源分配,使用目标负载均衡器提高云环境中的服务质量

Abstract In order to manage the load on dispersed data centers and cut down on energy established on time usage, agent-based resource allocation is given attention. Using a targeted load balancer (TLB), we suggest an energy-aware agent-based resource allocation in this research to enhance quality of service in a cloud setting. This agent is first set up to keep track of the resource load resulting from the request that has been assigned a job. Cloud watch also keeps an eye on energy levels to determine the typical payload size of resource execution. The TLB establishes new instance state to assign the resource based on the payload weight. To shorten the execution time, the dynamic hyper switching model develops a balancing mechanism. The suggested system achieves high performance in resource management by creating load balancer that is efficiently targeted to cut down on computation time and cost depending on energy levels. In comparison to existing techniques, the suggested parallelized homogeneous job in the cloud environment produces greater performance up to 95.5% while maintaining the time execution utilizing switching state of execution. This maintains the reduced CPU consumption, which dependent on the lowering of temporal complexity.
摘要为了管理分散数据中心的负载,减少基于时间的能源消耗,基于agent的资源分配受到关注。在本研究中,我们建议使用目标负载平衡器(TLB)进行基于能量感知代理的资源分配,以提高云环境中的服务质量。首先设置此代理来跟踪分配作业的请求所产生的资源负载。Cloud watch还关注能量水平,以确定资源执行的典型有效负载大小。TLB根据负载权重建立新的实例状态来分配资源。为了缩短执行时间,动态超交换模型开发了一种平衡机制。建议的系统通过创建负载平衡器来实现高性能的资源管理,该负载平衡器有效地减少了计算时间和成本,这取决于能量水平。与现有技术相比,建议在云环境中并行化同构作业产生更高的性能,最高可达95.5%,同时利用切换执行状态保持时间执行。这样可以降低CPU消耗,这取决于时间复杂度的降低。
