Cloud systems by virtue characterize ultimate resource utilization with ever evolving user requirements facilitating adaptivity. With a scope of enhancing the QoS needs applications, numerous factors are considered for tunning among which Task scheduling promises to grab focus. The Scheduling mechanism ascertains improvement distributing subtasks specific set resources pertaining prevailing Qua...

This article aimed to design and simulated the speed control of a three-phase induction motor using PI controller with Space Vector Pulse width modulation technique. The used in this is was designed at Electrical Energy Conversion Laboratory, Riau University, power 1.1 kW, 380 V, 2-pole. Meanwhile, constants designing were determined Fine Tunning method obtain KP KI values 3.539 9.526, respecti...

Abstract Inconel 625 alloy is a nickel-based deformation superalloy which widely used in aviation, ocean engineering, chemical engineering and other important fields. In recent years, with the continuous expansion application field of alloy, requirements mechanical properties, corrosion resistance comprehensive properties are constantly improved. this paper, hardness tester, tensile machine, el...

In momentum space, the nodal loop is regarded as a ring-shaped band degeneracy and classified into type-I type-II configurations depending on positive/negative dispersions of degenerating bands. Here, we experimentally observe new class in photonic structure, employing an artificially designed bilayer metasurface. Such degeneracy, termed type-III loop, formed by crossing between resonant flat p...

In this paper we present a centralised flightby-wire system based on μ-synthesis approach to the longitudinal flight motion of our experimental flying wing unmanned aerial vehicle (UAV), P15035 aircraft. The challenge associated with our UAV is related to the fact that all motions of our UAV are controlled by two independently-actuated-ailerons, together with its throttle. The first reason for ...

In order to reduce power consumption in data dominated embedded applications, a multi-level memory hierarchy containing caches is often introduced in the implementation. The cache memory used in this hierarchy must have simple tag-comparison mechanisms and tag array overhead for reduced energy. However, such cache architecture, a direct mapped cache, potentially also causes energy overhead due ...

The early Universe inflation [11] is well known as a promising theory to explain the origin of large scale structure of the Universe, a causal theory for the origin of primordial density fluctuations which may explain the observed density inhomogeneities and cosmic microwave fluctuations in the very early Universe, and to solve the early universe pressing problems for the standard hot big bang ...

Abstract Differential evolution algorithm (DE) is a well-known population-based method for solving continuous optimization problems. It has simple structure and easy to adapt wide range of applications. However, with suitable population sizes, its performance depends on the two main control parameters: scaling factor ( F ) crossover rate CR ). The classical DE can achieve high by time-consuming...
