The rapid growth of published cloud services in the Internet makes the service selection and recommendation a challenging task for both users and service providers. In cloud environments, software re services collaborate with other complementary services to provide complete solutions to end users. The service selection is performed based on QoS requirements… (More)
The living anionic polymerization of isocyanates carried out using conventional initiators is associated with side reactions due to rapid initiation rates as well as back-biting by the growing chain, resulting in a lack of control on the molecular weight (MW) and molecular weight distribution (MWD) of the polymers. Successful control over the reaction was… (More)
QoS-based service selection has been an active research area in both Service Computing and Cloud Computing communities in recent years. One of the obstacles for many researchers is lack of benchmark QoS datasets, especially for cloud service selection. In this paper, we propose a testbed system which can be used to collect the QoS data for software services… (More)
The effect of solvent compositions on the micellization behaviors of amphiphilic poly(n-hexyl isocyanate)-b-poly(2-vinylpyridine)-b-poly(n-hexyl isocyanate) (PHIC-b-P2VP-b-PHIC) rod-coil-rod triblock copolymer was studied. In absolute methanol the block copolymer formed hollow spherical micelles. These micelles transformed into giant-tubes by simply… (More)
The rod-like chains wrap tangentially to the curved interface of the spherical cores of the rod-coil micelles and vesicles that are reversibly interchangeable by varying the polymer concentration.
The rapid growth of published cloud services in the Internet makes the service selection and recommendation a challenging task for both users and service providers. Services' QoS properties such as response time and throughput are often used to select the best of functionally equivalent services. In cloud environment, software services collaborate with… (More)
Morphologies of the poly(n-hexyl isocyanate)-block-poly(2-vinylpyridine) (PHIC-b-P2VP, fP2VP=0.3) amphiphilic rod-coil block copolymer were studied in rod-selective chloroform (CHCl3), both-block-soluble tetrahydrofuran (THF), and CHCl3/THF mixed solvent systems. Spherical, solid micelles with a P2VP core and PHIC shell were formed in CHCl3, whereas a… (More)
