Contribuição do uso da terra e do manejo do solo para a recarga de aquíferos.

Neste texto é apresentada uma visão da pesquisa quanto à importância do conhecimento edafoambiental e do monitoramento do efeito de tecnologias e práticas de manejo e de conservação dos recursos naturais - solo, água e biodiversidade - de ocorrência nas denominadas zonas de recarga de aquíferos. O objetivo principal é a construção de cenários futuros, capazes de predizer a eficácia das tecnologias e das práticas em uso e formular propostas para a recarga dos sistemas hídricos brasileiros. Para isso, são necessários estudos envolvendo as relações hídricas (pluviométrica, subterrânea e superficial) e edafoambientais (solo, clima, uso potencial e atual) que permitam a compreensão da complexidade envolvida na recarga dos aquíferos, tendo como componente integrador o processo de infiltração vertical da água pluvial.bitstream/CNPS-2010/14888/1/comtec32-2005-recarga-aquiferos.pd

Prevention of advancing degradation and recovery of degraded lands.

This chapter presents an overview on the main technological contributions of Embrapa and partners to halt land degradation, accelerated erosive processes, desertification, sanding, salinization, and to restore degraded lands, as established in target 15.3 (United Nations, 2018): By 2030, combat desertification, restore degraded land and soil, including land affected by desertification, drought and floods, and strive to achieve a land degradation-neutral world.bitstream/item/204882/1/Prevention-of-advancing-degradation-and-recovery-of-degraded-lands-2019.pd

Serious Games in Cultural Heritage

Although the widespread use of gaming for leisure purposes has been well documented, the use of games to support cultural heritage purposes, such as historical teaching and learning, or for enhancing museum visits, has been less well considered. The state-of-the-art in serious game technology is identical to that of the state-of-the-art in entertainment games technology. As a result the field of serious heritage games concerns itself with recent advances in computer games, real-time computer graphics, virtual and augmented reality and artificial intelligence. On the other hand, the main strengths of serious gaming applications may be generalised as being in the areas of communication, visual expression of information, collaboration mechanisms, interactivity and entertainment. In this report, we will focus on the state-of-the-art with respect to the theories, methods and technologies used in serious heritage games. We provide an overview of existing literature of relevance to the domain, discuss the strengths and weaknesses of the described methods and point out unsolved problems and challenges. In addition, several case studies illustrating the application of methods and technologies used in cultural heritage are presented

Verification of Magnitude and Phase Responses in Fixed-Point Digital Filters

In the digital signal processing (DSP) area, one of the most important tasks is digital filter design. Currently, this procedure is performed with the aid of computational tools, which generally assume filter coefficients represented with floating-point arithmetic. Nonetheless, during the implementation phase, which is often done in digital signal processors or field programmable gate arrays, the representation of the obtained coefficients can be carried out through integer or fixed-point arithmetic, which often results in unexpected behavior or even unstable filters. The present work addresses this issue and proposes a verification methodology based on the digital-system verifier (DSVerifier), with the goal of checking fixed-point digital filters w.r.t. implementation aspects. In particular, DSVerifier checks whether the number of bits used in coefficient representation will result in a filter with the same features specified during the design phase. Experimental results show that errors regarding frequency response and overflow are likely to be identified with the proposed methodology, which thus improves overall system's reliability

Relação entre o intervalo de partos e o custo total de produção de leite por vaca no rebanho.

O intervalo de partos foi a variavel de maior impacto nos custos de producao de vacas da raca holandesa de primeira e segunda lactacoes, seguida da producao total de leite. A idade ao primeiro parto e o valor genetico relacionaram-se apenas com o custo de producao de vacas holandesas de primeira lactacao. No caso de vacas mesticas (HZ) de primeira e segunda lactacao apenas o intervalo de partos e a producao total de leite relacionaram-se com o custo total.Resumo expandido
