in this study, porous scaffolds from poly(d,l-lactic acid) have been prepared via liquid- liquid phase separation method in ternary system of polymer-1,4-dioxane-water. polymer dissolved in dioxane in 1.5, 2.5 and 5 % wt/v and the solvent/non-solvent ratios were 13/87, 15/85 and 17/83. cloud point curves prepared by visual turbidometry. in order to obtain porous scaffolds with inter-connected p...

Cloud computing has become one of the fastest growing fields in computer science. As the new computing service pattern of cloud computing develops rapidly, the security problem of cloud computing has become a hot research topic. Before the user passes important data or computing task to the cloud, the user of the cloud may want to verify the trusted status of the platform which actually carries...

Cloud radiative kernels and histograms of cloud fraction, both as functions of cloud-top pressure and optical depth, are used to quantify cloud amount, altitude, and optical depth feedbacks. The analysis is applied to doubled-CO2 simulations from 11 global climate models in the Cloud Feedback Model Intercomparison Project. Global, annual, and ensemble mean longwave (LW) and shortwave (SW) cloud...

Cloud computing offers its customer‘s reliable service at flexible prices that do not break the bank. However, as good and innovative as cloud computing may be, it does not necessarily mean that cloud computing is good for all businesses. By researching the cloud computing services available, I will explore the benefits, as well as the drawbacks of cloud computing within the business realm. Fir...

Cloud Platform is a platform where cloud applications runs. It is an online platform, which works over internet. Cloud Platform has been constructed of three layers: “SaaS”, “PaaS”, and “IaaS”. Many companies in market i.e. Google, Microsoft, IBM etc used to provide cloud platform on per click basis and as well free of cost. The Google cloud platform is used to deploy cloud applications and the...

The vulnerability of Cloud Computing Systems (CCSs) to Advanced Persistent Threats (APTs) is significant. So a cloud architecture reference model that incorporates a wide range of security controls and best practices, and a cloud security assessment model – Cloud-Trust – that estimates high level security metrics to quantify the degree of confidentiality and integrity offered by a CCS or cloud ...

Cloud computing has emerged as a fast-growing paradigm for storing/sharing data and delivering services over the Internet. It provides its users with a way to deal with information or data without investing in any new technology or resources of their own. Although cloud computing environment is viewed as a promising Internet-based computing platform, the security challenges it poses are also eq...

The handling of unstructured data in database management system is very difficult. The managing unstructured data like image, video textual data etc. are not easy task in database system. In this work a concept of cloud algebra introduced to handle unstructured data in CDBMS. The most popular concept, relational algebra is used in relational database management system. The relational algebra is...
