In the recent era of cloud computing, huge demand for virtual resource provisioning requires mitigating challenges uniform load distribution as well efficient utilization among machines in datacenters. Salp swarm optimization is one simplest, yet metaheuristic techniques to balance VMs. The proposed methodology has incorporated self-adaptive procedures deal with unpredictable population tasks b...

This paper proposes a new algebraic scheme to design a PID controller for higher order linear time invariant continuous systems. Modified PSO (MPSO) based model order formulation techniques have applied to obtain the effective formulated second order system. A controller is tuned to meet the desired performance specification by using pole-zero cancellation method. Proposed PID controller is att...

The reaction pathways following electronic excitation of 10-methyl phenothiazine (MPS) in the presence of oxygen have been investigated as a contribution to establish the mechanisms involved in the phototoxic reactions related to phenothiazine drugs. In the context of previously published results, the pathways of oxidation via the radical cation and/or by reactive oxygen species, such as single...

Advanced power converters are being developed due to the latest developments in electronics switches. The matrix converter (MC) assessment is product of this drastic growth. MC a bidirectional flow device with single-step energy conversion mechanism that operates at variable voltage and frequency. main drawback presence harmonics electronic switching. A lot research has been done decrease conte...

چکیده- در این مقاله، طراحی کنترل کننده تناسبی- انتگرالی- مشتقی (تام) بهینه بر مبنای "الگوریتم بهینه سازی بهبود یافته اجتماع پرندگان" (ePSO) ارائه می شود. مزیت این روش جدید نسبت به روش‌های متداول در طراحی کنترل کننده این است که ارائه آن محدود به کلاس خاصی از سیستم‌ها نیست. در طراحی کنترل کننده تام بهینه، مجموع زمان صعود، زمان نشست، فراجهش و انتگرال قدر مطلق خطا کمینه می­شوند. سه نوع الگوریتم بهی...
