Recently, cloud systems composed of heterogeneous hardware have been increased to utilize progressed hardware power. However, to program applications for heterogeneous hardware to achieve high performance needs much technical skill and is difficult for users. Therefore, to achieve high performance easily, this paper proposes a PaaS which analyzes application logics and offloads computations to ...

Transitioning cloud-based Hadoop frameworks from IaaS to PaaS, which are commercially conceptualized as pay-as-you-go or pay-per-use, often reduces the associated system costs. However, managed systems obscure inner performance dynamics of platform and present a black-box behavior end-users. The aim this study was investigate resource utilization current platforms. Thus, we explored three promi...

Analisou-se, sob a perspectiva do gestor e de profissionais saúde, uma proposta metodológica trabalho em grupos para promoção da alimentação adequada saudável (PAAS) na Atenção Primaria à Saúde baseada no referencial Paulo Freire. Trata-se um estudo qualitativo, qual foram realizadas entrevistas com roteiro semiestruturado e, posteriormente, transcritas analisadas pela técnica análise conteúdo....

Two different disulfide (SS)-containing poly(amidoamine) (PAA) polymers were constructed using guanidino (Gua)-containing monomers (ie, arginine [Arg] and agmatine [Agm]) and N,N'-cystamine bisacrylamide (CBA) by Michael-addition polymerization. In order to characterize these two Gua-SS-PAA polymers and investigate their potentials as short hairpin RNA (shRNA)-delivery carriers, pSilencer 4.1-C...

It is proved that cloud computing has many benefits, and cloud services with flexible licensing model and cost saving features bring opportunities to enterprise's IT operations. Conventional ERP system, an important component of enterprises, is impacted by on-demand cloud services also. Integrating conventional ERP system with cloud services becomes a trend because it brings new processing capa...

Cloud computing (CC) has gained much popularity. Large amounts of data, many of them personal, are consumed by CC services. Yet, data security and, derived from that, privacy are topics that are not satisfyingly covered. Especially usage control and data leakage prevention are open problems. We propose the development of a trusted Platform as a Service CC architecture that addresses selected Da...
