This paper aims to focus on the usability evaluation of two interactive and popular cloud PaaS (Platform as a Service) providers namely Microsoft Azure and Appharbor. Usability evaluation has been carried out in two stages: Performance evaluation is carried out by taking CPU Utilization, Memory Usage and Disk Seeking Rate as essential parameters and in next stage customer satisfaction is measur...

Poly(A) has significant relevance to mRNA stability, protein synthesis and cancer biology. The ability of two phenothiazinium dyes azure A (AA) and azure B (AB) to bind single-stranded poly(A) was studied by spectroscopic and calorimetric techniques. Strong binding of the dyes and the higher affinity of AA over AB were ascertained from absorbance and fluorescence experiments. Significant pertur...

BACKGROUND To expand on the range of products which can be obtained from lignocellulosic biomass, the lignin component should be utilized as feedstock for value-added chemicals such as substituted aromatics, instead of being incinerated for heat and energy. Enzymes could provide an effective means for lignin depolymerization into products of interest. In this study, soil bacteria were isolated ...

I was the shadow of the waxwing slain By the false azure in the windowpane; I was the smudge of ashen fluff-and I Lived on, flew on, in the reflected sky. PREFACE This thesis is thought to be reflective of the transformation, mistily rendered in the citation on the previous page, which has taken place in me since I have handed in my Ph.D. thesis in the spring of 1996. If this transformation, no...

We propose to use cloud computing for solving constraint programing problems in parallel. We used the Embarrassingly Parallel Search (EPS) method in conjunction with Microsoft Azure, the cloud computing platform and infrastructure, created by Microsoft. EPS decomposes the problem in many distinct subproblems which are then solved independently by workers. EPS has three advantages: it is an effi...

Overview In cloud-infrastructure, cloud service providers (e.g. Amazon Web Service, IBM Cloud, Microsoft Azure) are not allowed to access the content of customer virtual machines. In consequence, it is hard for the providers to protect their infrastructure from malware infections. As the virtual machines are usually created from a limited set of standard images and likely share many vulnerabili...

Geoprocessing functions are important for discovering hidden and useful geospatial information, and are widely used in Earth science modeling and applications. The growth of the Web has resulted in the Web-based sharing of large volumes of distributed geospatial data and computational resources. Processing heterogeneous and distributed data into information requires a powerful, scalable, and in...

Abstract Virtual machines (VMs) are preferred by the majority of organizations due to their high performance. VMs allow for reduced overhead with multiple systems running from same console at time. A physical server is a bare-metal system whose hardware controlled host operating system. runs on single instance OS and application. virtual or machine encapsulates underlying networking resources. ...
