Internet of Things: Spectral Demand in Mexico
Authors: Ruíz José Luis Cuevas 
Published: May 2019

Purpose – The present text seeks to examine the amount of spectrum to be used, mainly due to the scarcity and costs of the same, for the implementation of IoT services with high demand, based on the conditions of Mexico.
Methodology/approach/design – The present study will analyze the conditions of bandwidth demand and connection speeds for certain IoT applications. For the calculation of the bandwidth, the procedure used to obtain the bandwidth requirements considering different work cycles for various IoT applications is applied; This procedure has been applied for the estimation of the bandwidth in smart cities in India. The procedure makes use of population data to determine the current and potential density of IoT devices connected through wireless networks; At the same time, an area of coverage of the network is calculated, considering the typical radio coverage for urban, semi-urban and rural areas. With the above data, it is possible to obtain the number of devices in the coverage area of the network and with this the total traffic demand, to finally estimate the value of the bandwidth.
Findings – Considering the five regions with the highest population density, the amount of bandwidth was projected up to the year 2023. The spectral needs can vary considerably from one area to another. The results obtained present a direct dependence on the size of the cell to be considered. The radio coverage of the cell can vary depending on the type of geographical area, so that an increase of 1 km in the coverage radius could represent an increase of up to twice the spectrum demand.

Published: May 2019

Purpose – Economic activity is based increasingly on the Internet. This development generates multiple benefits for consumers but also competition challenges for operators and regulatory authorities.
Methodology/approach/design – The study considers the recent evolution of the traditional voice, messaging and video telecommunications services, as well as OTT of similar functionality that coexist in the markets with them. Based on the literature review, the degree of substitution and / or complementarity between traditional services and OTT is analyzed from a demand perspective.
Findings – No conclusions can be set, as certain conditions of consumption substitution is observed, while in others, complementarity between services. From the perspective of suppliers, there is a certain complementarity that is reflected in a greater number of associations between operators and OTT.
Integrated purchasing and banking data protection in the context of Directive (EU) 2015/2366: new payment service providers
Authors: Legeais Dominique 
Published: May 2019

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.

Sistem Information Retrieval (IR) maupun chatbot semakin banyak dikembangkan. Salah satu bagian yang banyak diteliti adalah cross language. Masalah pada pengembangan cross language yaitu terjadinya kesalahan pada hasil terjemahan mesin translasi yang memberikan arti tidak sesuai dengan bahasa natural, sehingga pengguna tidak mendapatkan jawaban yang semestinya, bahkan tidak jarang pula pengguna tidak menemukan jawaban. Penelitian ini mengusulkan skema baru mesin translasi yang bertujuan meningkatkan performa dalam masalah ambiguitas. Mesin translasi bekerja dengan cek kebenaran kata kunci, kemudian melakukan Part-of-Speech (POS) Tagging pada kata benda (noun). Kemudian, setiap kata benda yang terdeteksi akan dicari sinonimnya. Lalu, sinonim yang didapatkan akan ditambahkan dan menjadi alternatif kueri baru. Kueri yang mempunyai nilai confident tertinggi diasumsikan sebagai kueri yang paling sesuai. Pada hasil yang didapatkan setelah dilakukan uji coba, melalui penambahan metode yang kami usulkan pada machine translation, dapat meningkatkan akurasi chatbot dibandingkan tanpa menggunakan skema yang diusulkan. Hasil akurasi bertambah 5%, dari yang semula 73% menjadi 77%. Information retrieval and chatbot systems are increasingly being developed with its language part mostly studied. However, the problem associated with its development is the occurrence of errors in the translation machine resulting in inaccurate answers not in accordance with the natural language, thereby providing users with wrong answers. This study proposes a new translation machine scheme that aims to improve performance while translating ambiguous terms. Translation machines functions by checking the correctness of keywords, and carrying out Part-of-Speech (POS) Tagging on nouns (noun). The synonyms of any detected noun are searched for and obtained added to become alternative new queries. Those with the highest confident value are assumed to be the most appropriate. The results obtained after testing, through the addition of the method proposed in machine translation, can improve the accuracy of the chatbot compared to not using the proposed scheme. The results of the accuracy increased from the original 73% to 77%.

Receiver function seismology
Authors: Vinnik L. P. 
Published: May 2019

The application results of the receiver function technique are briefly outlined. The topography of the main seismic boundaries in the mantle transition zone is evaluated with resolution of about 3 km in depth and about 200 km laterally. The maximal amplitudes of depth variations of the main boundaries reach tens of kilometers. The mantle transition zone thinning in the hot spots and the respective increase in temperature by ~100 °C is established. In several regions, two low-velocity layers are revealed in the mantle transition zone, one directly above the 410-km seismic discontinuity and another at a depth of 450 to 500 km. The origin of the first layer is associated with dehydration in the mantle plumes during olivine – walesite phase transformation. The increase in the S-wave velocity at the base of the second layer can explain the observations of the so-called 520-km boundary. The traditional approach to studying the structure of the crust and upper mantle is from surface waves. Receiver functions can provide higher resolution at the same depths when a combination of P- and S-wave receiver functions is used. This type of results was obtained for Fennoscandia, Kaapvaal craton, Indian shield, Central Tien Shan, Baikal rift zone, the Azores, Cape Verde Islands, and the western Mediterranean. S-receiver functions were used in the studies of the lunar crust. The joint P- and S-receiver function inversion provides robust estimates of the parameters of seismic boundaries including weak discontinuities such as the lithosphere – asthenosphere interface of cratons. The parameters determined from receiver functions include the P- to S-wave velocity ratio. In a few regions, a very high (> 2.0) velocity ratio is observed in the lower crust, probably indicating the presence of a fluid with high pore pressure. Receiver functions allow estimating the parameters of azimuthal anisotropy as a function of depth. The changes of the parameters with depth make it possible to distinguish the active anisotropy associated with recent deformations from the frozen anisotropy – the effect of the past tectonic processes.
