Appropriate performance evaluations of commercial Cloud services are crucial and beneficial for both customers and providers to understand the service runtime, while suitable experimental design and analysis would be vital for practical evaluation implementations. However, there seems to be a lack of effective methods for Cloud services performance evaluation. For example, in most of the existi...

Design of Experiment (DOE) is a widely used method for examining experiments especially in industrial production and robust design processes. This set statistical approaches which mathematical models are developed through experimental testing to estimate possible outputs given input values or parameters. The aims determine the main factors that affect results with smallest number studies. In th...

Design of experiment (DoE) techniques are invaluable tools which readily allow for efficient optimisation processes via simultaneous evaluation a combination input parameters. Such approaches can yield positive outcomes whilst minimising the number resources and amount time utilised, hence, achieving more robust approach. Additionally, when designing intelligently information about interaction ...

This paper presents an optimization of the hull separation, i.e. transverse clearance. The main objective is to identify the feasible speed ranges and find the optimum transverse clearance considering the minimum wave-making resistance. The dimensions and the weight of hardware systems installed in the catamaran structured fuel cell powered USV (Unmanned Surface Vehicle) were considered as cons...

We present a design of experiments (DOE) technique for microwave/millimeter wave flip chip characterization and optimization. Two optimization approaches, signal bump misalignment and transmission line compensation, are combined together for optimal performance for high frequency operation. First, the design of experiments method is presented and its advantages are emphasized. Then, the two tec...

In this paper, we present the design and optimization of a centrifugal fan with requirements maximizing total-to-static pressure rise efficiency at two operating points maximum torque provided by motor power using 3D inverse method, DOE (design experiment) study, an RSM (response surface model) MOGA (multi-objective genetic algorithm). The geometry is parametrized 13 parameters, 120 different d...

Abstract Electrospinning is a well-known and straightforward technique for creating nanofibres from various materials, such as metals, ceramics, polymers. The process takes place in strong electric field, causing the polymer solution to stretch, resulting micro/nanoscale fibres. parameters of electrospinning influence morphology nanofibres. In present study, zinc oxide (ZnO) were created polyvi...
