[1] Our understanding of the activation of aerosol particles into cloud drops during the formation of warm cumulus clouds presently has a limited observational foundation. Detailed observations of aerosol size and composition, cloud microphysics and dynamics, and atmospheric thermodynamic state were collected in a systematic study of 21 cumulus clouds by the Center for Interdisciplinary Remotel...

The malicious usage of the cloud platform, untrusted providers, and untrusted perception from the users all contribute to the difficult application of the cloud services. In order to solve these issues, a trust evaluation method of the cloud service based on user perception is proposed. Based on fuzzy set theory, the behaviors of nodes in the cloud platform are quantitated, and the trust values...

We perform numerical simulations of nonlinear MHD waves in a gravitationally stratified molecular cloud that is bounded by a hot and tenuous external medium. We study the relation between the strength of the turbulence and various global properties of a molecular cloud, within a 1.5-dimensional approximation. Under the influence of a driving source of Alfvénic disturbances, the cloud is lifted ...

Cloud computing has emerged rapidly as an exciting new paradigm that offers a challenging model of computing and services. Leveraging cloud computing technology, bioinformatics tools can be made available as services to anyone, anywhere, and through any device. The use of large biodatasets, its highly demanding algorithms, and the hardware for sudden computational resources makes large-scale bi...

Cloud computing is recognized as an emerging paradigm in today’s business environment. Nevertheless, it is not completely a new technology, it is widespread due to the fast development of the internet, mobile phones, higher bandwidth and increasing mobility requirements of the clients. In spite of the fact that the adoption of cloud computing services is proliferating in large companies, SMEs s...
