Design de Relações entre tecnologias amigáveis e sociabilidades virtuais: um novo campo de investigação para o Design

The Digital Age, with its new interactive and converging technologies, stimulates original forms of sociability, which are interconnected, intercommunicating and virtualized through hyperscreens. Another kind of interaction arises from the digitization and new speeds of contemporary communicative process. With the new order of knowledge, it is now possible to transgress the limits of physical space and linear time sequence, through the collective development of content through such telematics networks. Youth gives voice to a new type of user, or a social actor, whose thinking is connected to other communication habits, consolidating singular cultural standards, demanding new languages and skills. Here, we address the nature of this Design of new relations, interactions, behaviors and social systems that emerge in the so called Information Society.

A contribuição do projeto de identidade coorporativa na redução da poluição visual

Among Richard Wagner´s work output one finds the Tetralogy The Ring of the Nibelung, composed of four stories interconnected by the same plot. The theme is mythological and involves dramatis personae taken from the nordic universe. This article examines Erda, one of the protagonists of the story as she is called in the musical drama. This article will consist of a series of pertinent questions posed in order to fully understanding of the character and its role in the plot, the vocal type assigned to it and the co-relation between its Leitmotiv and the musical interweaving created by the composer, besides exploring other themes that bear direct relationship with the same.

Simulação numérica de fluxo de águas subterrâneas na bacia do Rio Corrente (BA)

The numeric simulation is an important tool applied in understanding the dynamics of groundwater flow. In a hydrogeological model the processes responsible for groundwater flow are described by numerical formulations that allow the simplification, representation and understanding of the dynamics of the Aquifer System. In this work, a steady state groundwater flow simulation of Urucuia Aquifer System (UAS) part of the Corrente river basin was conducted, using the finite element method through software FEFLOW, to understand the dynamics of groundwater flow and quantify the hydrologic balance. The aquifer system Urucuia lodges in the São Francisco hydrogeological province and corresponds to a set of interconnected aquifers that occur in rocks from Urucuia group in the Urucuia sub-basin described by Campos e Dardenne (1997). The system is a porous media one, in a shape of a thick table mountain, consisting essentially of sandstones. The Corrente river basin is located in UAS in Western State of Bahia and it's one of the main units to maintaining permanent flow (Q95) and average natural flow of the São Francisco river. The simulation performed in this work obtained the following results for the modelled region: horizontal hydraulic conductivity of 3 x 10-4 m/s and vertical one 6 x 10-5 m/s; maximum recharge of 345 mm and minimum of 85 mm/a. It was concluded that: (1) regional groundwater flow has eastbound; with an exception of the extreme northeast portion, where the flow has opposite direction; (2) there are smaller water side dividers with an approximate direction EW, that guide the flow of water to the drainage that cut the aquifer; and (3) the UAS at Corrente river basin can be understood as a free regional aquifer system, isotropic and homogeneous. Regionally, the small lithological variations present in the Urucuia group can be neglected and do not exhibit significant influences on the dynamics of ground water flow

Transparent vs. Opaque vs. Translucent Wavelength-Routed Optical Networks

A wavelength-routed optical network consists of multi-wavelength crossconnect switches (XCSs) which are interconnected by optical fibers. Some (or all) crossconnects, referred to as nodes in this paper, are also attached to access stations where data from several end-users could be multiplexed onto a single wavelength division multiplexed (WDM) channel. An access station provides optical-to-electronic (O/E) conversion and wice wersa to interface the optical network with conventional electronic equipment. The access station, at an intermediate node, may also be used (as in this study) for signal regenerution on a lightpath. A new call is admitted into the network if a lightpath (a set of free wavelengths along a given route from source to destination) can be established between the call’s source and destination stations. Depending on the number of all-optical fragments in a single lightpath, three different approaches may be employed to operate such a network. These approaches are: transparency, opacity, and translucency (to be explained below). Our study concentrates on evaluating the relative merits of these three approaches in a sample network environment.

Global Competence: Determination of its Importance for Engineers Working in a Global Environment

We live and work in a world that is even more interconnected and interdependent than ever before. Engineers must now not only develop technical engineering competence, but must also develop additional skills and competencies including global competence to obtain success within a global engineering environment. The purpose of this study was to determine whether multinational companies considered global competence an important skill in mechanical engineering graduates when making hiring decisions. The study was an exploratory study that utilized an extensive literature review to identify eight global competencies for engineering success within a global environment and also included a survey instrument completed by Brigham Young University (BYU) mechanical engineering alumni in 48 states and 17 countries. The study focused on an evaluation of standard hiring technical engineering competencies with eight global competencies identified in the literature review. The study established that standard engineering technical competencies were the most important consideration when hiring mechanical engineers, but global competence was also considered important by a majority of all survey respondents with six of the eight global competencies rated important by 79 to 91% of respondents with an ability to communicate cross-culturally the highest-rated global competence. The importance of global competence in engineers when making hiring decisions, as considered by large companies who employed more than 10,000 employees or who had annual revenue exceeding $1 billion (US$) per year, was particularly strong. The majority of respondents (70%) indicated that companies were willing to provide training and experience to help engineers obtain success in a global engineering environment. In addition, a majority of respondents (59.9%) indicated that companies valued the efforts of higher educational engineering institutions to prepare engineers for success in a global environment with only 4.8% of respondents indicating that they did not value the efforts of higher education engineering institutions. However, only 27% of respondents agreed that colleges and universities were successful in this endeavor. Globalization is not a passing phenomenon, it is here to stay. Colleges and universities throughout the world need to recognize the importance of globalization and the interdependence and interconnectedness among the world’s population. Therefore, it is important to identify, develop, and provide opportunities for international collaboration and interaction among students and faculty throughout the world and to focus on developing global competence as an important outcome for engineering graduates.

An Artesian Well System in Beaver Crossing, Nebraska- It's Development and Demise

ABSTRACT Nebraska has a veritable wealth of groundwater. The High Plains Aquifer underlies most of the state, and within its sand and gravel deposits, many interconnected aquifers provide fresh water for a variety of uses. One of the most spectacular examples of this resource is the artesian well. Beaver Crossing, Nebraska was once home to one of the most prolific artesian systems in the state before its demise. Founded in the 1880’s, Beaver Crossing soon became known for its many artesian wells, that provided leisure activities and supported profitable business ventures such as small farming, ice production and aquiculture. Eventually these wells would dry up and the town of Beaver Crossing would never see the level of commerce and activity that it saw during its early years. I decided to research this subject because I lived in Beaver Crossing for twelve years. While I lived there I heard stories about the artesian wells, the nationally recognized lily pond, and the large public pool fed by underground water that was plentiful around town. I was interested in knowing what happened to the water, the wells, the pool and businesses. . . And, in the wake of their disappearance, what happened to the town. To research this topic I looked at accounts of the history of Seward County and Beaver Crossing. I also studied the basic geology underlying the Great Plains, as well as local geology and issues pertaining to groundwater levels, such as rainfall amounts, drought and irrigation. As irrigation became a factor in rural Nebraska and through several documented droughts, groundwater levels all over the state declined. At the same time the artesian system in Beaver Crossing all but disappeared.

Direito de livre expressão e direito social à informação na era digital

O artigo procura aprofundar o tema da liberdade de expressão e do direito à informação, tal como concebidos na democracia que se estabelece a partir da idéia de que todo o poder emana do povo e em seu nome é exercido, nos marcos da comunicação contemporânea postos pelas novas tecnologias e pelas redes interconectadas. A liberdade de expressão e o direito à informação de fato se expandem na era digital? Em que termos? Há novos constrangimentos para esses direitos fundamentais? Quais os desafios?

Improved low-voltage-ride-through capability of fixed-speed wind turbines using decentralised control of STATCOM with energy storage system

The design and implementation of a new control scheme for reactive power compensation, voltage regulation and transient stability enhancement for wind turbines equipped with fixed-speed induction generators (IGs) in large interconnected power systems is presented in this study. The low-voltage-ride-through (LVRT) capability is provided by extending the range of the operation of the controlled system to include typical post-fault conditions. A systematic procedure is proposed to design decentralised multi-variable controllers for large interconnected power systems using the linear quadratic (LQ) output-feedback control design method and the controller design procedure is formulated as an optimisation problem involving rank-constrained linear matrix inequality (LMI). In this study, it is shown that a static synchronous compensator (STATCOM) with energy storage system (ESS), controlled via robust control technique, is an effective device for improving the LVRT capability of fixed-speed wind turbines.

Optimization of Large-Scale Hydrothermal System Operation

This paper presents the development of a mathematical model to optimize the management and operation of the Brazilian hydrothermal system. The system consists of a large set of individual hydropower plants and a set of aggregated thermal plants. The energy generated in the system is interconnected by a transmission network so it can be transmitted to centers of consumption throughout the country. The optimization model offered is capable of handling different types of constraints, such as interbasin water transfers, water supply for various purposes, and environmental requirements. Its overall objective is to produce energy to meet the country's demand at a minimum cost. Called HIDROTERM, the model integrates a database with basic hydrological and technical information to run the optimization model, and provides an interface to manage the input and output data. The optimization model uses the General Algebraic Modeling System (GAMS) package and can invoke different linear as well as nonlinear programming solvers. The optimization model was applied to the Brazilian hydrothermal system, one of the largest in the world. The system is divided into four subsystems with 127 active hydropower plants. Preliminary results under different scenarios of inflow, demand, and installed capacity demonstrate the efficiency and utility of the model. From this and other case studies in Brazil, the results indicate that the methodology developed is suitable to different applications, such as planning operation, capacity expansion, and operational rule studies, and trade-off analysis among multiple water users.

A novel strategy for building interoperable MPI environment in heterogeneous high performance systems

Breakthrough advances in microprocessor technology and efficient power management have altered the course of development of processors with the emergence of multi-core processor technology, in order to bring higher level of processing. The utilization of many-core technology has boosted computing power provided by cluster of workstations or SMPs, providing large computational power at an affordable cost using solely commodity components. Different implementations of message-passing libraries and system softwares (including Operating Systems) are installed in such cluster and multi-cluster computing systems. In order to guarantee correct execution of message-passing parallel applications in a computing environment other than that originally the parallel application was developed, review of the application code is needed. In this paper, a hybrid communication interfacing strategy is proposed, to execute a parallel application in a group of computing nodes belonging to different clusters or multi-clusters (computing systems may be running different operating systems and MPI implementations), interconnected with public or private IP addresses, and responding interchangeably to user execution requests. Experimental results demonstrate the feasibility of this proposed strategy and its effectiveness, through the execution of benchmarking parallel applications.
