“…A sintaxe no sentido usado por Charles W. Morris é a que trata da investigação das combinações possíveis de significantes, pelo sentido saussuriano, ou seja, "o exemplo do significante é sempre uma imagem material, captável pelos sentidos" (TRABANT, 1980, p.42); -o modo pelo qual os signos de várias classes se combinam para formar signos compostos (MASER, 1975) e depois as regras de transformação; -localizam-se as unidades estruturantes do processo, características definidoras ou fundamentais da forma (SILVA, 1985); -não há o detalhamento dos problemas desses significantes, tais como suas constituições específicas, materiais, elementos de arranjo, etc. devendo ser subsidiados por disciplinas recentes (TRABANT, 1980); -o isolamento das partes pela sintaxe permite delimitar os elementos, destacando suas características e facilitando a análise (MASER, 1975).…”

The architecture has been strongly expanded in its complexity by the resources of computing, promoting significant changes in the way, the resignation of the common range of appearances and the search for experiences with unusual versions, creating visual metaphors for a new world. Space enunciations intertwine several variables with many scientific motes to explore, in an intense and systematic use of digital media, thus resulting plastic holdings processes with different affinities to the scope of the digital arts. The projects of digital architectures are underpinned by the characteristics given in the code and with specific internal rules in which those instructions were given to certain degrees of autonomy machine. Thus, the hypothesis of this study assumed the flexible assemblages of rules, in which computer codes are able to promote the creation of unpredictable abstract structures (not able to be reached by human reason without the assistance of computers) that contains complex character grounds similar to the arts. As a kind of cultural metaphor, digital architecture can materialize signs of a very wide range of related and underlying the way the desire for expression translated into a character of beauty. Even in experimental or poetic investigation cases, this approach fits into the context of the technical and the built environment production processes. In this thesis of digital processes is analyzed, presenting the concepts and founding elements of very heterogeneous work: MRGD Architects, Tom Wiscombe Architecture, Zaha Hadid Architects, Jerry Tate Architects and Kokkugia. Discussions of these digital architectures are performed by the concepts of architectural sign second syntax categories, semantics and pragmatics of Charles William Morris semiotics, and other approaches of Charles Sanders Pierce.

Reservoir operation and environmental water demand: Scenarios for the Sub‐Middle and Lower São Francisco River basin, Brazil

et al. 2018

View full text Add to dashboard Cite

Water management is important for delivering water for different users and uses.Reservoirs are built to overcome the stochastic nature of river flows and to increase the reliability of water supply. Reservoir operation affects the ecology of downstream river sections, and there has been a discussion of a more ecologically oriented flow regime, although ecosystems of reservoirs themselves are rarely taken into account.For reservoirs, it is important to identify multiple impacts and trade-offs of different management options. This information can be used in a multidisciplinary and multiparticipatory decision-making process to assess the management options. This study develops, applies, and discusses reservoir operation options for the São Francisco River basin (Brazil): (a) Reference; (b) Environmental discharge; (c) Reduced daily water-level variation; and (d) Reduced annual water-level variation. In the simulation study, the operation option with reduced daily water-level variation in reservoirs turned out to be the most flexible, guaranteeing hydropower generation and water supply in the dry season, while considering the ecology of the reservoirs and rivers. The simulations are exemplary for decision makers, requiring further assessment after agreeing on priority setting.

This paper proposes the use of a floating solar photovoltaic (FSPV) power plant as an alternative renewable energy resource for the San Francisco River Integration Project (SFIP), which aims to deliver water to 12 million people in the Brazilian semiarid. The SFIP requires considerable amounts of energy in a region that has had increasing electricity costs and consumption of water in the past decade. By simulating an FSPV power plant at the System Advisor Model (SAM) using techniques and parameters of real FSPV projects, the results demonstrated the techno-economic feasibility of this technology linked to the SFIP. The economic outcomes are positive net present value (NPV), $2.8 million, and a payback varying from 10.5 to 11.7 years. The levelized cost of electricity (LCOE) of $32.17/MWh is smaller than the current energy rates paid by the SFIP administrator, and the water costs to final consumers could be reduced by 40%. In addition, the FSPV's capacity factor was 21.1%, and the system could minimize water evaporation from one of the SFIP's reservoirs by 16.7%. The system can also create revenues for the San Francisco and Parnaiba Valleys Development Company (CODEVASF) by trading the excess of electricity with the grid. This paper also analyses the FSPV's environmental impacts and its relevance under the water-energy nexus in the Brazilian Northeast. The FSPV could minimize the SFIP's operational costs, avoid environmental impacts, and improve the efficiency of water and energy management. Such components are crucial when analyzing the water-energy nexus in such a region, marked by strong competition for water access and long periods of drought.
