<p><strong>O APLICATIVO UBER: UM ESTUDO DE CASO BASEADO NOS PRINCÍPIOS E FUNDAMENTOS DA ORDEM ECONÔMICA NA CONSTITUIÇÃO FEDERAL DE 88 </strong></p><p><strong>Resumo:</strong> Os princípios da ordem econômica são positivados na atual Constituição da República Federativa do Brasil com o escopo de conferir segurança jurídica na economia brasileira. Considerando que o Estado delimita em sua Lei Fundamental quando e como pode interferir no mercado, bem como esclarece quais princípios norteiam sua política econômica, o presente estudo propõe-se a tecer uma preocupada análise acerca da proibição equivocada do serviço de transporte de passageiros na modalidade privada no Brasil. Uma prestadora desses serviços, a Uber do Brasil Tecnologia LTDA, tem sido alvo de questionamentos da legalidade de suas atividades. O presente trabalho problematizará a questão das novas tecnologias no direito, mormente quando a prestação do serviço ou o exercício da atividade afrontam a legislação atual, um direito administrativo engessado e a doutrina clássica em desafinação com o tempo presente. O objetivo deste artigo é demonstrar que o transporte individual de passageiros em sua modalidade privada está em consonância com o atual ordenamento econômico da Constituição, a Política Nacional de Mobilidade Urbana, e o posicionamento do Ministério Público Federal, resguardando, assim, a autonomia do particular no exercício legal de sua profissão e contribuição com a economia do país.</p><p><strong>Palavras-chaves:</strong> Ordem econômica constitucional; princípios econômicos; transporte privado; Uber; mobilidade; novas tecnologias; atividade econômica; serviço público.</p><p><strong>THE UBER APPLICATION: A CASE STUDY BASED ON THE PRINCIPLES AND FOUNDATION OF ECONOMIC ORDER IN THE FEDERAL CONSTITUTION OF 88</strong></p><p><strong>Abstract:</strong> The principles of economic order are implemented in the current Constitution of the Federative Republic of Brazil with the aim of providing legal certainty to the Brazilian economy. Whereas the State delimits under its Basic Law when and how to intervene in the market, and clarifies what principles should guide its economic policy, the purpose of this monograph is to offer a concerned analysis on the mistaken prohibition imposed on private passenger transport service in Brazil. A supplier of such services, Uber do Brasil Tecnologia LTDA, has been undergoing some questioning regarding the legality of their activities. This paper will question the matter of new technologies under the Law, particularly when the service performance or the exercise of the activity is against current legislation, a plastered administrative law, and the classical doctrine in disagreement with present time. This controversy will be addressed in an exclusive chapter and will be present throughout this study. With all this exposure, the objective is to show that the private individual passenger transport is in line with the current economic order of the Constitution, the National Urban Mobility Policy and the position of the Federal Prosecution Service, and, consequently, protecting the autonomy of private parties in the lawful exercise of their profession and contribution to the Brazilian economy.</p><p><strong>Keywords:</strong> Constitutional Economic Order; economic principles; private transport; Uber; mobility; new technologies; economic activity; public service.</p><p><strong>Data da submissão:</strong> 29/10/2016                   <strong>Data da aprovação:</strong> 01/12/2016</p>

Mobility System

Travelers interact with a large number and variety of products and services during their journeys. The quality of a travel experience depends on a whole urban mobility system considered in space and time. This paper outlines the relevant concepts to be considered in designing urban mobility. The goal is to provide a language and insights for the early stages of a design process. A literature review sheds light on the complexity of urban mobility from technical, sociotechnical, and user experience perspectives. Observations of experiences in urban areas provide data for describing and understanding travel experience patterns and issues. The paper proposes a conceptual model to describe and analyze different facets of traveler experience and categorizes problems that travelers face when they interact with an urban mobility system. A case study is reported illustrating the use of the conceptual model in identifying travel problems for a demand-responsive transport service.

<p>The Soil Science Institute of Thessaloniki produces new digitized Soil Maps that provide a useful electronic database for the spatial representation of the soil variation within a region, based on in situ soil sampling, laboratory analyses, GIS techniques and plant nutrition mathematical models, coupled with the local land cadastre. The novelty of these studies is that local agronomists have immediate access to a wide range of soil information by clicking on a field parcel shown in this digital interface and, therefore, can suggest an appropriate treatment (e.g. liming, manure incorporation, desalination, application of proper type and quantity of fertilizer) depending on the field conditions and cultivated crops. A specific case study is presented in the current work with regards to the construction of the digitized Soil Map of the regional unit of Kastoria. The potential of this map can easily be realized by the fact that the mapping of the physicochemical properties of the soils in this region provided delineation zones for differential fertilization management. An experiment was also conducted using remote sensing techniques for the enhancement of the fertilization advisory software database, which is a component of the digitized map, and the optimization of nitrogen management in agricultural areas.</p>

Photovoltaic panel efficiency can be heavily affected by soiling, due to dust and other airborne particles, which can determine up to 50% of energy production loss. Generally, it is possible to reduce that impact by means of periodic cleaning, and one of the most efficient cleaning solutions is the use of demineralized water. As pauperization of traditional water sources is increasing, new technologies have been developed to obtain the needed water amount. Water extracted from the air using air to water generator (AWG) technology appears to be particularly suitable for panel cleaning, but its effective employment presents issues related to model selection, determining system size, and energy efficiency. To overcome such issues, the authors proposed a method to choose an AWG system for panel cleaning and to determine its size accordingly, based on a cleaning time optimization procedure and tailored to AWG peculiarities, with an aim to maximize energy production. In order to determine the energy loss due to soiling, a simplified semiempirical model (i.e., the DIrt method) was developed as well. The methodology, which also allows for energy saving due to an optimal cleaning frequency, was applied to a case study. The results show that the choice of the most suitable AWG model could prevent 83% of energy loss related to soling. These methods are the first example of a design tool for panel cleaning planning involving AWG technology.

Heritage Buildings

Sustainable design is believed to stand on the opposite side of heritage conservation. This view is supported by the fact that sustainable design requires invasive measures to implement new technologies and treatments that challenge the principle of minimum intervention in heritage conservation. Another point of view sees heritage conservation as an already act of sustainable development that protects and preserves social and cultural resources such as heritage buildings and their intangible values. On the other hand, research and practice have proven that heritage buildings can be the subjects of sustainable design projects that achieve outstanding measures of sustainability and energy efficiency while not compromising the authenticity of the heritage value of the building. This sustainable conservation reaches its peak in adaptive-reuse projects of heritage buildings as reusing the building guarantees its ongoing maintenance and promotes its social, cultural and economic values to society, while giving it the ability to withstand modern users’ comfort and energy efficiency standards. This research presents a case study of the adaptive-reuse project of Villa Antoniadis in Alexandria; a heritage building built in the mid-nineteenth century and in the process of a major adaptive-reuse project. The history and significance of the building will be studied as well as the conservation values of the current project, then some proposals for interventions that could achieve more energy efficiency for the project while conserving the building are discussed. The research included a simulation of the building, using building energy modelling software for the current adaptive-reuse project as a base case, and the hypothetical application of different proposed sustainable interventions such as thermal insulation, double glazing, shading, lighting control, natural ventilation, and photovoltaic energy generation, where the energy savings potentials for each proposed intervention were studied. The simulation proved a possible reduction of 36.5% in the cooling, heating and lighting energy consumption as well as generated 74.7% of the energy required for cooling, heating and lighting from renewable energy sources.

Am Processes

Additive manufacturing (AM) has experienced a phenomenal expansion in recent years and new technologies and materials rapidly emerge in the market. Design for Additive Manufacturing (DfAM) becomes more and more important to take full advantage of the capabilities provided by AM. However, most people still have limited knowledge to make informed decisions in the design stage. Therefore, an interactive DfAM system in the cloud platform is proposed to enable people sharing the knowledge in this field and guide the designers to utilize AM efficiently. There are two major modules in the system, decision support module and knowledge management module. A case study is presented to illustrate how this system can help the designers understand the capabilities of AM processes and make rational decisions.
