1. Evaluation of the Heat and Energy Performance of a Datacenter Using a New Efficiency Index: Energy Usage Effectiveness Design – EUED.
Abstract Data Centers are growing steadily worldwide, and they are expected to continue growing up to 53% in 2020. Energy efficiency, in high power consumption, is a key venue. There are methodologies to measure this efficiency, one example is using the PUE (Power Usage Effectiveness) index. In this paper is proposed a new index for measuring efficiency at

2. FairCPU: Uma Arquitetura para Provisionamento de MÃquinas Virtuais Utilizando CaracterÃsticas de Processamento / FairCPU: An Architecture for Provisioning Virtual Machines Using Processing Features
Resource scheduling is a key process for cloud computing platform, which generally uses virtual machines (VMs) as scheduling units. The use of virtualization techniques provides great flexibility with the ability to instantiate multiple VMs on one physical machine (PM), migrate them between the PMs and dynamically scale VMâs resources. The techniques of con

3. Vibration attenuation and shape control of surface mounted, embedded smart beam
Active Vibration Control (AVC) using smart structure is used to reduce the vibration of a system by automatic modification of the system structural response. AVC is widely used, because of its wide and broad frequency response range, low additional mass, high adaptability and good efficiency. A lot of research has been done on Finite Element (FE) models for

4. Iluminação natural em setores de produção de edifícios industriais : estudos de caso na região metropolitana de Campinas / Daylighting in manufacturing sectors of industrial buildings : case studies in the metropolitan region of Campinas
Although daylighting is a renewable resource, clean and costless, support to energy efficiency of a built environment and promoter of wellness state and health, it is not yet used in an efficient way in industrial building design, probably because architects and its clients ignore its principles, resources and possibilities. On the other hand, one notes an i

5. AnÃlise da Outorga de Direito de Uso dos Recursos HÃdricos no Estado do Cearà / Analysis of Grant of Right to Use Water Resources in the State of Ceara
This study is an analysis of the system for granting rights of usage of water resources, currently developed in the State of CearÃ. This analysis was based on data relating to the grant, provided by the managing agencies (SRH and COGERH). In reviewing the literature, the concept of grant was analysed in the legal and technical contexts and have discussed th

6. Contribuições ao estudo comparativo dos efeitos de descargas atmosféricas em sistemas compostos por cabos aéreos e subterrâneos a seco e a óleo
By means of computing simulations, it is presented in this work a comparative study of the effects of electromagnetic transients proceeding from indirect and direct atmospheric discharges in mixed-transmission lines, which consist of aerial and underground parts with oil and dry type isolation. The developed and implemented model in the ATP computing environ

7. Projeto e desenvolvimento de um dispositivo de avaliação do rolamento do pe de idosos durante a marcha / Projecting and developing a device to feet roll-over gait evaluation in aged people
Feet roll-over is fundamental to assure an efficient human gait but aging brings body system s alterations that cause modifications in gait s feet roll-over and diminishes gait s efficiency. This work s proposal was to elaborate and develop a device in order to simultaneously acquire e record plantar load distribution during gait and to give sound stimuli th

8. An automated speculative trading system proposal / Uma proposta para um sistema automatizado de tomada de decisão financeira especulativa
In this work we present the development of an automatic trading system based upon simplified time series models that, when applied on prices of liquid financial assets, derivatives and indexes, and with parameters adjusted by extensive back testing and reality conditions checks (Hansens SPA test), seeks to reach out financial returns that exceed the traditio

9. Effects of ZmDof1 and OsDof25 transcriptional factors superexpression on nitrogen usage efficiency in Arabidopsis. / Efeito da superexpressão dos fatores de transcrição ZmDof1 e OsDof25 sobre a eficiência de uso de nitrogênio em Arabidopsis.
To improve nitrogen usage efficiency in plants the rice transcriptional factor OsDof25 was identified and cloned, whose probably orthologe is the maize ZmDof1, already identified and partially characterized. The ZmDof1 was also cloned for comparative analysis with OsDof25, in order to confirm this last one as ZmDof1 orthologe in rice. The constructions for A

10. Evaluation of CTMP pulp´s behavior towards hydrogen peroxide bleaching: utilization of sub/supercritical carbon dioxide / Avaliação do comportamento de polpa CTMP frente ao branqueamento com peróxido de hidrogênio: utilização de dióxido de carbono no estado sub/supercrítico
The bleaching of chemithermomechanical pulp (CTMP) is usually performed using hydrogen peroxide (H2O2) in alkaline medium. This stage produces high quantity of effluent to be treated, increasing the costs of the industrial process. The usage of liquid carbon dioxide (CO2) under sub/supercritical conditions can help in reducing the amount of liquid effluents
