  • A filtering technique for n-way stream joins in wireless sensors networks

    Purpose - The join operations between data streams need more time and request more energy than traditional joins. In wireless sensor networks, energy is a critical factor. The survival of the network depends on this energy, thus it is necessary to consider, for this type of queries in such networks, the reduction of the sensors' energy consumption. While works that have been done to treat n-way join operations between data streams are rare so far, we propose a technique, named NSLSJ (N-way Stream Local Semi-Join) to perform this type of join operations. The principal aim is to considerably reduce the consumed energy. Methodology/approach/design - The technique 'N-way Stream Local Semi-Join (NSLSJ) proposed in this paper is based on an in-network execution, and on filtering tuples strategy for an important gain in energy. Findings - Compared to NSLJ and Sens-Join techniques, NSLSJ shows better performances in the realized tests as it consumes less energy

  • Multi Band Metamaterials Absorber for Stealth Applications

    Purpose - This paper presents a simulation study using CST microwave studio computer software. Methodology/approach/design - A simple structure based on metamaterial are used to construct a perfect metamaterial absorber. It is made of just one uncompleted square patch copper placed on top of dielectric layer to separate it from a copper ground plate. Findings - This design provides four perfect absorption regions with absorption peaks of an average of 93%. The characteristic study of parameters such as copper dimensions and dielectric properties led to an expected result in the synthesis of resonant frequency. Practical implications - The multi-band absorption can be used in energy harvesting applications, protection from the effects of electromagnetic waves, radar stealth technology and thermal imaging. Moreover, the experimental results show good agreement with CST simulation

  • Multilayer, locality aware, telecommunication network deployment algorithm

    Purpose - In this paper we propose an iterative approach for the deployment of rural telecommunication networks. Methodology/approach/design - This approach relies heavily on the concept of locality, prioritizing small ‘cells' with a considerable population density, and exploits the natural nesting of the distribution of rural communities, focusing in communities which are populous enough to justify the investment required to provide them with connectivity, and whose sheer size promotes the formation of ‘satellite' communities that could be benefited from the initial investment at a marginal expense. For this approach, the concept of ‘cells' is paramount, which are constructed iteratively based on the contour of a Voronoi tessellation centered on the community of interest. Once the focal community has been ‘connected' with network of the previous layer, the process is repeated with less populous communities at each stage until a coverage threshold has been reached. One of the main contributions of this methodology is that it makes every calculation based on ‘street distance' instead of Euclidean, giving a more realistic approximate of the length of the network and hence the amount of the investment. To test our results, we ran our experiments on two segregated communities in one of the most complicated terrains, due to the mountain chains, in the state of Chiapas, Mexico. Findings - The results suggest that the use of ‘street distance' and a local approach leads to the deployment of a remarkably different network than the standard methodology would imply. Practical implications - The results of this paper might lead to a significant reduction in the costs associated with these kinds of projects and therefore make the democratization of connectivity a reality. In order to make our results reproducible, we make all our code open and publicly available on GitHub

  • Design and Testing of Fractal Antenna Parameters based on the Koch Curve for Reception of Digital Terrestrial Television Signals in the UHF Band

    Purpose - In this research paper, the electrical and radiation characteristics of a proposed fractal antenna based on the Koch curve in the second iteration for reception of digital terrestrial television signals are designed and analyzed by laboratory tests. Methodology/approach/design - The design is based on the concepts of fractal geometry and on a previously designed antenna, which is adapted to obtain a different frequency of operation; the designed antenna is constructed in three different ways, finally, they are tested in the lab using vector-network-analyzer, that allows to measure parameters, such as: VSWR, gain and radiation pattern. Findings - The fractal antenna based on the Koch curve has the necessary characteristics to receive digital terrestrial television signals in the UHF band

  • Integrated purchasing and banking data protection in the context of Directive (EU) 2015/2366: new payment service providers

    Purpose - The article analyses the limits of protection of bank users´ data in France, framing them as personal data. Its legal analysis is made amidst a context of radical changes in the European and French personal data protection law as well in the banking regulation, which is being transformed by the new payment services regulation. Methodology/approach/design - The article brings an interlacement of some new legal sources from the European and French law to appraise the limits of banking data protection. It tests the application of some legal norms in order to evaluate the potential protection in two areas: the security of the banking data on a new environment of payment services (fintechs and other new firms); the possibility of protection against the unauthorized data commercial usage. Findings - The article concludes that the European and French banking and payment services law have not the desired level of protection against bad commercial practices in a context, which is marked by both the retailers and payment services integration as well the presence of the big techs. The data protection law must complement the banking and payment services regulation in order to provide the desired level of protection. Practical implications - The article demonstrates the possibility of testing new kinds of legal regulation - data protection - to archive social and economic security in a different sector, like baking and commerce. Originality/value - The article departs from a new concept of banking data, built from the meshing of the concepts of banking information and sensible personal data. From this conceptual frame, it can evaluate the level of protection granted by the European and French law in order to sketch a possible protective regime

  • The effectiveness of French contract law in the face of Internet giants

    Purpose - The article analyzes the French contract law in order to assess its usefulness to provide regulatory means of the big techs. It shows that the recent reforms of the French contract law have not been able to empower the consumers and result in a stronger protection against abuse. Methodology/approach/design - The article evaluates the contractual relations between the big techs and their users, with a special regard to the French law (general contract law, the commercial law, and the consumer law). It demonstrates the limits of the general contract law due to the complexity of the contractual subject, named as Internet service. In addition, the article assesses the means of protection: liberty to contract, codes of conduct, and, judicial lawsuits. Findings - The article concludes that the French contract law will only be able to offer effective protective results by benefitting the Internet users if there is an increase of the collective lawsuits, filed by consumers´ protection groups or by state agencies like the Ministry of the Economy. Two other solutions exist, such as codes of conduct and the recognition of more liberty to the users. However, they both have specific limitations to produce effective results

  • The Internet giants and the future of the liability legal regime applicable to the technical intermediaries in the European and French Law

    Purpose - The article brings an examination of the legal regime of civil liability of the content and stockage Internet providers (technical intermediaries) under the European and French law in order to evaluate the possibilities of a new regulatory design, which may provide a better balance between the rights and obligations of those technical intermediaries. Methodology/approach/design - The research uses legal articles and rulings to provide an analysis of the European and French regarding the civil liability of the technical intermediaries to assess the limits of the current legal regulatory regime. Findings - Extracting data from rulings, technical reports and academic legal texts, the article shows the possibility of legal construction of new regulatory means that may provide a better balance between rights and obligations of the technical intermediaries

  • Judicial Control of State Regulation in light of Jürgen Habermas's thought: Analysis of the Decisions issued by the Brazilian Superior Court of Justice on Long-Distance-like Calls within the same Municipality or between Conurbated Municipalities

    Purpose - This article seeks to examine the possibility and limits of judicial control of regulatory agencies decision-making power in Brazil based on the ideas of communicative action and integrity proposed by Jürgen Habermas. Methodology/approach/design - There will be made an analysis of the decisions of the Superior Court of Justice regarding the charge of long-distance-like calls within the same municipality or between conurbated municipalities. Findings - Superior Court of Justice, in most of its cases, privileges the technical criteria adopted by the regulatory agency, understanding that the judicial review would be an improper invasion of a “technical” area. However, there are decisions of the same Court that kept the judicial review carried out by the Courts of Appeal, in flagrant contradiction. The lack of a more consistent reasoning and, above all, of consistency among the decisions reveal the lack of attention on the part of the Brazilian Superior Court of the criteria of integrity advocated by Jürgen Habermas

  • Mapping the origin of digital inequalities: an empirical study about the city of São Paulo

    Purpose - Approaches that attribute inequalities in access and use of the Internet to structural economic factors and contemplate the reproduction of individual off-line characteristics in the digital environment are predominant in the specialized literature. Recently, however, the focus has been shifting to the differences in patterns of digital inclusion according to characteristics of particular communities or territories. Methodology/approach/design - The empirical study investigates to what extent the territory matters to explain the variability of Internet use and the existence of ICT skills. Based on a sample survey conducted in 2016, the study analyses data collected on the city of São Paulo/Brazil. Findings - The results indicate that, in addition to socioeconomic conditions, territorial aspects are important for understanding digital inequalities. Nonetheless, it suggests that the level of territorial disaggregation must be taken into consideration when measuring the use of the Internet and ICT skills. Practical implications - The study highlights the need for deeper theoretical and methodological considerations of social, institutional and regulatory factors that affect the scenario of online inequalities, including place-based effects of urban policies
