Purpose: Relative dispersion analysis (RDA), a new high pass resolution perimetry (HRP) index, appears to capture a novel aspect of visual field abnormality. The aim of this study was to evaluate the correlation of RDA and other HRP indices with the Humphrey perimeter parameters. Methods: Fifty-six eyes were randomly recruited from among patients at the authors’ clinic. Twenty-nine eyes were cl...

Cloud computing has emerged as a new computing paradigm that offers great potential for storing data remotely. Presently, many organizations have reduced the burden of local data storage and maintenance by outsourcing data storage to the cloud. However, integrity and security of the outsourced data continues to be a matter of major concern for data owners due to the lack of control and physical...

در این پایان نامه به بررسی یک آرایه retrodirective array (rda) می پردازیم، و با هدف کاهش سخت افزار مورد نیاز برای طراحی، از آنتن هایی با خاصیت حذف هارمونیک استفاده می کنیم. در بین ساختارهای مورد استفاده در کاربردهای مخابراتی، نیاز به سیستمی که پس از دریافت موج، موجی در جهت منبع ارسال موج بفرستد، احساس می شود. کارکرد مهم یک rda، که آن را از سایر ساختارهای مخابراتی متمایز می کند، داشتن چنین ویژگ...

This paper proposed a red deer algorithm (RDA)-based selective harmonic elimination (SHE) method for multilevel inverters (MLIs). To eliminate the desired orders, optimum switching angles of MLI have been calculated using RDA. The applied to 3-phase cascaded H-bridged 11-level inverter. In addition, performance RDA was compared with results methods such as Newton-Raphson (NR) method, LSHADE/EpS...

INTRODUCTION Critically ill patients suffer from oxidative stress caused by reactive oxygen species (ROS) and reactive nitrogen species (RNS). Although ROS/RNS are constantly produced under normal circumstances, critical illness can drastically increase their production. These patients have reduced plasma and intracellular levels of antioxidants and free electron scavengers or cofactors, and de...
