The purpose of this paper is to present a comprehensive study of latest and most famous facial features extraction techniques and as well as classification techniques. We studied these techniques in two different perspectives; one is spatial domain and other is frequency domain. We found many advantages and disadvantages of each technique inside one domain(More)
• We provide an overview of the research within Data Center Networks (DCNs). • We present the state-of-the-art energy efficiency techniques for a DCN. • The survey elaborates on the DCN architectures (electrical, optical, and hybrid). • We also focus on traffic management, characterization, and performance monitoring. • We present a comparative analysis of(More)
Available online xxxx a b s t r a c t Integration of large number of electronic components on a single chip has resulted in complete and complex systems on a single chip. The energy efficiency in the System-on-Chip (SoC) and its communication subset, the Network-on-Chip (NoC), is a key challenge, due to the fact that these systems are typically(More)
— In modern computing paradigms, energy consumption is of foremost importance because it constitutes a major percentage of the operational expenses. Virtual Machines (VMs) are consolidated on a fewer number of servers to significantly reduce the overall power consumption. The idle servers are then turned off by using Dynamic threshold Voltage Scaling(More)
INTRODUCTION Echinococcosis is produced by the larval stage of Echinococcus granulosus; it is a parasitic disease which is seen rarely in humans and has adverse outcomes. We report a case of advanced pelvic hydatid bone disease with successful limb salvage surgery. Our patient had a 5-year follow-up without recurrence which is a rarity as per the(More)
