1. Fast Optimization of Tuned Mass-Spring Arrangement for Reduction of Acoustic Power Radiation of Submerged Ribbed Cylinder
Abstract In this paper, acoustic power radiation of a submerged finite length ribbed cylinder subject to a harmonic point load is minimized by a new fast scheme. For this purpose, two arrangements of non-uniformly distributed sequential point masses and mass springs attached on stiffening ribs of the cylinder are used to optimally reduce the acoustic power r

2. Cloud computing: searching its use in public management environments
Abstract The research investigated the perception about cloud computing (CC) in public management environments. After, from the perspective of information technology (IT) people on those organizations, it has raised views on how IT in the cloud is seen as a solution for government-level service delivery. Then, managers of the top public management of two cit

4. Estudo exploratório sobre fontes de os jitter no kernel linux
The OS Jitter phenomenon has been considered an important factor in high-performance distributed computing. In this thesis, we present the results of an experimental study that quantifies the effects of different sources of OS Jitter in the Linux operating system. We use the DOE method to conduct controlled experiments statistically planned. Differently than

9. Uma infraestrutura para aplicações distribuídas baseadas em atores Scala / An infrastructure for distributed applications based on Scala actors
Escrever aplicações concorrentes é comumente tido como uma tarefa difícil e propensa a erros. Isso é particularmente verdade para aplicações escritas nas linguagens de uso mais disseminado, como C++ e Java, que oferecem um modelo de programação concorrente baseado em memória compartilhada e travas. Muitos consideram que o modo de se programar conco

11. UTILIZATION OF DHT IN DISTRIBUTED COMPUTING SYSTEMS / APLICAÇÕES DE DHT EM SISTEMAS DE MPUTAÇÃO DISTRIBUÍDA
P2P architectures are recognized for decentralization and incentive for the cooperation among nodes. These characteristics allow for fault tolerance and resource distribution among the nodes (by replication) to systems based on the P2P architecture. Systems based in P2P networks built using the DHT technique are scalable. Since this architecture is commonly
