This paper describes the e-Science Central (e-SC) cloud data processing system and its application to a number of e-Science projects. e-SC provides both software as a service (SaaS) and platform as a service for scientific data management, analysis and collaboration. It is a portable system and can be deployed on both private (e.g. Eucalyptus) and public clouds (Amazon AWS and Microsoft Windows...

Unstructured storage and data processing using platforms such as MapReduce are increasingly popular for their simplicity, scalability, and flexibility. Using elastic cloud storage and computation makes them even more attractive. However cloud providers such as Amazon and Windows Azure separate their storage and compute resources even within the same data center. Transferring data from storage t...

Nowadays cloud infrastructures allow storing and processing increasing amounts of scientific data. However, most of the existing large scale data management frameworks are based on the assumption that users deploy their data-intensive applications in single data center, few of them focus on the inter data centers data flows. Managing data across geographically distributed data centers is not tr...

Botnet has become one major Internet security issue in recent years. Although signature-based solutions are accurate, it is not possible to detect bot variants in real-time. In this paper, we propose behavior-based botnet detection in parallel (BBDP). BBDP adopts a fuzzy pattern recognition approach to detect bots. It detects a bot based on anomaly behavior in DNS queries and TCP requests. With...

First, this case study explores an Intrusion Detection System package called Snort (provided by Cisco Systems) in a cloud environment. Snort is an open source and highly scalable signaturebased intrusion detection system. Here, Snort is deployed on Ubuntu Server 16.0.4 running on a virtual machine within a Microsoft Azure cloud system. This paper provides details on installing Snort on the virt...

leukocyte physiology related to the genesis or perpetuation of the leukemic state. Ilistochemical,2,’ biochemical4 and fine structural studies5’t’ have defined a number of similarities between Auer rods and the primary dense particles of immature granulocytes, the azurophilic granules. The resemblance of the two types of cytoplasmic organelles has prompted the conclusion that Auer bodies are un...

A unique and simple colorimetric method for the quantitation of plasma protamine levels has been developed. The method is established on the competitive binding displacement mechanism between protamine and heparin-azure A dye complex, and the metachromatic color change of azure A dye in the presence of heparin. Because the method is based on the clinical specificity of protamine as the heparin ...
