This study aims to develop scientifically sound proposals and recommendations for implementing the principles and characteristics of digital monopolies and determine the patterns and relationships of individual products. To achieve the goal, methodological approaches used included correlation analysis. The results are methodological justifications to determine the key principles of digital monopolies within the service approach. The scientific novelty of the results is to identify the synergetic relationship of individual products of digital companies, which can be used to build an appropriate antimonopoly policy of the United States. The practical significance of the results consists of approbation of the proposed principles of digital monopolies on the example of the relationship of Google’s selected products.

Die Plattformen der Digitalkonzerne ziehen den Großteil der gesamtdeutschen digitalen Mediennutzung auf sich. Durch die extreme Konzentrationsbildung wurde fairer Wettbewerb auf dem Feld der digitalen Medien ebenso systematisch wie planvoll abgeschafft. Deswegen ist davon auszugehen, dass die GAFAs* infolge der digitalen Transformation in den kommenden Jahren unser Mediensystem übernehmen werden – eine Entwicklung, gegen die wir auf Grundlage der aktuellen Gesetzgebung weitgehend wehrlos sind. Dabei steht schon der Status Quo in einem eklatanten Widerspruch zu den antimonopolistischen Grundsätzen des klassischen deutschen Medienrechts. Zeit für eine Grundsatzdebatte. * Weil das Akronym „GAFA“ für Google, Apple, Facebook und Amazon allgemein gebräuchlich ist, wird der Begriff hier auch nach den Umbenennungen (Alphabet, Meta) als Sammelbezeichnung für die großen US-amerikanischen Digitalkonzerne verwendet.

The article deals with the issues of antimonopoly regulation of the activities of companies that are global digital giants. The activity of such companies is a kind of challenge for the antimonopoly authorities in all coun- tries of the world. Against the background of the pandemic, digital platforms are gaining special importance and are rapidly increasing their market share. During the period of active development of the digital economy, which is based on the information technology and innovative solutions, issues arise that are not typical for traditional markets for goods and services. There is a need to develop a new system of antitrust regulation that can protect competition, but at the same time takes into account the interests of companies operating in digital markets. In the digital economy, the main categories of antimonopoly regulation are fundamentally changing: it is more difficult to determine whet-her the price is monopoly; the points of application of the above regulation are shifting, as more and more transactions take place online and it is impossible to determine a specific responsible person; it becomes more complicated to form an evidence base in an antitrust case. Since the Internet overcomes both physical and legal boundaries, when building a regulatory system for the digital economy, it is necessary to take into account international experience and promote synchronization of the an- titrust laws of those countries where the largest players in digital markets are based. Participants in economic activity do not try to compete in some com- modity market, where are already many players, but generate new markets where they strive to become absolute monopolists. Today, “digital giants” have a large number of market power levers through the use and creation of new platforms, control and collection of data about users and product market par- ticipants, and the use of innovative methods of personalized marketing.

Cette thèse contribue à l’étude d’une des plus grandes entreprises contemporaines et peut-être la plus représentative du capitalisme contemporain : Amazon. L’objectif général de cette thèse est de placer le travail au cœur de l’analyse, en montrant sa centralité dans la production de la valeur, même dans ces corporations géantes que sont les « monopoles digitaux ». Avec son vaste réseau logistique et ses millions de salariés, Amazon est un cas d’étude privilégié pour comprendre (1) pourquoi ces monopoles, malgré leur caractère « digital », reposent sur des infrastructures physiques massives et comment ces infrastructures dépendent du travail, dans le cas d’Amazon du travail salarié, de millions de travailleuses et travailleurs, notamment dans les entrepôts logistiques ; (2) comment Amazon gère cette main d’œuvre pour faire en sort de mobiliser l’effort de ses salariés et en même temps de démobiliser leurs résistances, mais surtout comment ces stratégies changent en parallèle avec l’évolution de sa stratégie de profit (3) comment le caractère « disruptif » des monopoles digitaux se déploie dans des contextes historiques et institutionnels différents des États-Unis, notamment pour ce qui concerne les modes de régulations du travail et leur impact sur les conditions de travail chez Amazon. Pour répondre à ces trois question la thèse mobilise les résultats d’une enquête à plusieurs niveaux : le niveau procès de travail, étudié à travers l’observation participante, interviews avec les salariés et sources écrites ; le niveau de la stratégie de profit d’Amazon, examinée à partir de l’analyse des bilans d’entreprise, interviews avec le management ; le niveau des relations professionnelles locales et transnationales, analysées à travers l’observation directe des activités syndicales, interviews et l’exploitation de sources secondaires
This thesis contributes to the study of one of the largest contemporary companies and perhaps the most representative of contemporary capitalism: Amazon. The main goal of this thesis is to bring labour back at the core of the analysis, showing its centrality in the production of value, even in those giant corporations called “digital monopolies”.With its vast logistics network and millions of employees scattered across dozens of countries, Amazon is an ideal case study for understanding (1) why these monopolies, despite their “digital” nature, rely on massive physical infrastructures and how these infrastructures depends on the activity of millions of workers – in the case of Amazon, wage-workers, particularly in logistics warehouses; (2) how Amazon manages this workforce in order to mobilise the effort of employees while simultaneously demobilising their resistance, but above all how these strategies change at the same time as the evolution of Amazon’s profit strategy (3) how the “disruptive” power of digital monopolies unfolds in historical and institutional contexts other than those of the United States, particularly in terms of labour regulations and its impact on working conditions in Amazon’s workplace. To answer these three questions, the thesis mobilises the results of a multi-level investigation: the level of the labour process, studied through participant observation, interviews with employees and written sources; the level of Amazon’s profit strategy, examining the company’s balance sheets, interviewing management, and analysing vast secondary sources; the level of industrial relations, local and transnational, analysed through the direct observation of trade union activities, interviews and secondary sources

La tesi si compone di due progetti indipendenti. Il primo utilizza la metodologia real options per l'analisi delle politiche per lo sviliuppo di nuovi impianti rinnovabili. Propongo uno schema a sussidi crescenti nel tempo ed un price cap, di modo da aumetare la velocità di sviluppo di nuova capacità di produzione e contenere la spesa. Il secondo paper invece rappresenta il comportamento anticompetitivo di un'impresa digitale, un intermediario di dati, che estrae informazioni dai consumatori ed in seguito le alloca startegicamente presso le imprese, consentendo loro di offrire prezzi personalizzati. Inoltre l'intermediario riesce a sfruttare gli effetti di scala tipici delle tecnologie di produzione dei dati, per consolidare la sua posizione monopolistica.
The thesis consists of two independent projects. The first uses the real options methodology for the analysis of policies for the development of new renewable plants. I propose a subsidy scheme that increases over time and a price cap, in order to increase the speed of the development of new production capacity and contain spending. The second paper, on the other hand, represents the anti-competitive behavior of a digital company, a data intermediary, which extracts information from consumers and subsequently allocates it strategically to product firms, allowing them to offer personalized prices. Furthermore, the intermediary is able to exploit the scale effects, typical of data production technologies, to consolidate its monopolistic position.

A presente pesquisa trata o projeto e análise de uma antena monopolo planar com geometria modificada visando sua utilização para recepção do sinal de TV digital operante no Brasil na faixa de 470 MHz a 806 MHz. Faixa essa contida no espectro de UHF – Ultra High Frequency (300 MHz a 3 GHz). Para desenvolvimento desse trabalho foi tomado como referência à antena denominada “The Hi Monopole”. Que originalmente foi apresentada para operar em sistemas UWB (Ultra Wide Band) em 3,1 a 10,6 GHz. Para o desenvolvimento do trabalho proposto, diferentes técnicas de adequação da antena podem ser utilizadas para operação em banda larga, tais como: modificação na estrutura da antena, carregamento resistivo, chaveamento, utilização de elementos parasitas e estruturas de casamento. O projeto de antenas banda larga pode ser realizado a partir de três abordagens diferentes: domínio do tempo, domínio da frequência e método de expansão por singularidades. O método no domínio da frequência foi empregado neste trabalho para o projeto da antena proposta, algumas das técnicas supracitadas foram analisadas almejando o aumento da largura de banda, sendo confeccionado um protótipo da antena para validar os conceitos empregados. A antena foi então projetada para a faixa de 470 MHz a 890 MHz. O protótipo construído para essa mesma faixa apresentou bons resultados, o que valida à técnica empregada. Aspectos positivos e negativos do uso desta técnica são discutidos ao longo do trabalho. O programa computacional comercial CST® MICROWAVE STUDIO, baseado na Técnica da Integração Finita (FIT), foi usado para simulações no domínio da frequência.
This research deals with the design and analysis of a planar monopole antenna with modified geometry aiming its use for signal reception of digital TV in Brazil working in the of 470 MHz to 806 MHz. Track this contained in the spectrum of UHF-Ultra High Frequency (300 MHz to 3 GHz). To develop this work was taken as reference the antenna called "The Hi Monopole". What originally was presented to operate in UWB (Ultra Wide Band) at 3.1 to 10.6 GHz. For the development of the proposed work, different techniques of adjustment of the antenna can be used for broadband operation, such as: changes in the structure of antenna, resistive loading, switching, using of parasitic elements and matching structures. The design of broadband antennas can be made from three different approaches: time domain, frequency domain and expansion for singularities method. The frequency domain method was employed in this work to the antenna design proposed, some of the techniques mentioned above were analyzed aiming to increase bandwidth, and made a prototype of the antenna to validate the concepts employed. The antenna was designed for the range of 470 MHz to 890 MHz. the prototype built for this same range presented good results, which validates the technique employed. Positive and negative aspects of use of this technique are discussed throughout the work. The commercial computer program CST® MICROWAVE STUDIO, based on the Finite Integration Technique (FIT) was used for simulations in frequency domain.

Resumo: Este trabalho apresenta a implementação de um esquema de religamento monopolar adaptativo rápido baseado na medição do conteúdo harmônico da tensão da fase aberta nas extremidades da linha de transmissão. O objetivo principal deste esquema é controlar e reduzir o tempo compreendido entre a abertura e o religamento da fase em falta, como também bloquear a manobra em caso de faltas permanentes. O esquema proposto foi implementado em um relé de distância e um medidor de conteúdo harmônico. O método está baseado na identificação do instante de extinção da corrente de arco secundário para casos de faltas transitórias. Já para faltas permanentes é implementado o bloqueio da manobra automática e a abertura tripolar do disjuntor da linha protegida. A medição do conteúdo harmônico foi feita primeiramente utilizando um medidor de qualidade de energia comercial, que realiza a medição do conteúdo harmônico de acordo com a norma IEC 61000-4-3. Em seguida, foi utilizado outro método de medição do conteúdo harmônico, chamado de filtro de medição do conteúdo harmônico rápido, elaborado dentro do Simulador Digital em Tempo Real (RTDS). O sistema de transmissão utilizado foi modelado no RTDS e seus dados são dados reais do sistema interligado nacional (SIN). As faltas monofásicas transitórias foram simuladas utilizando o modelo de arco do próprio RTDS. Já para falta permanente utilizou-se uma resistência de 1 'ômega'. O esquema foi avaliado através de testes variando o ponto de aplicação do defeito e o valor da corrente de arco secundário
Abstract: This work presents the implementation of a scheme of fast adaptive single-phase reclosing based on measuring the voltage harmonic content at the opened faulty phase terminals. The main objective of this scheme is to control and to reduce the time between opening and reclosing of the phase in fault, and also to block the maneuver in case of permanent faults. The proposed scheme is implemented in a distance relay and a harmonic content meter. The method is based in the identification of the secondary arc current extinction moment for transient faults cases. For permanent faults an automatic blocking followed by circuit-breaker three-phase opening is implemented. The measurement of harmonic content was made initially using a commercial power quality meter, which performs the harmonic content measurement according to IEC 61000-4-3 standard. Another harmonic content measurement method was tested, the fast harmonic content filter measurement, elaborated within the real-time digital simulator (RTDS). The transmission system used was modeled on RTDS and the data corresponds to an actual Brazilian 500 kV system. To represent the transient single-phase fault it was used RTDS arc model. The permanent fault was modeled with an 1'ômega' resistance. The scheme was evaluated by varying the fault application point and the secondary arc current value

The present work constitutes a first attempt of understanding the digitalization of economy for what concerns platforms, which exploit two sides of market to make profits, by using targeted advertising built on personal “free” data. First, we analyse the nature of targeted advertising. We focus on the impact of ads on well-being of consumers. The possibility of having too much advertising calls for a government fiscal action that can be welfare-enhancing under some circumstances. Moreover, in a context of open economy, the decisions made by a government may spread their effects also abroad. Then, we study in deep how a two-sided platform works. We introduce a new element to the related literature. Users care about their privacy, but they do not know the actual level of their data mining. We deal with two issues: privacy protection and the need for government of raising fiscal revenue. Finally, we enlarge our approach by asking why a government should intervene by changing the market equilibrium. In an optimal taxation framework, we draw a method to address persuasive advertising when “undesired” by the government and show how it mixes with distributional concerns.

The digital television reception system has a number of possible technological changes in its architecture. One of the changes is the transition from the VHF broadcast band to UHF. This fact requires a change in design, size and electrical characteristics of the radio receiver antenna side. Among the desirable characteristics of an antenna operating in this frequency band are: omnidirectionality, gain, directivity and wideband required to cover the entire range, combined with low cost and easy construction. This work proposes a new antenna, formed by a planar monopole acting as irradiator element and supported by a conical structure attached to a cylindrical shaped element with sleeve format that promotes an increase and control of the bandwidth required to cover the entire UHF band, including GSM850 and GSM900 bands. The design of the proposed antenna was performed with a full wave electromagnetic field simulator. A prototype was built and simulated and experimental results showed that the proposed antenna could cover the range of 469.6 MHz to 1387.4 MHz, with a steady-state wave ratio of less than 2. The performance of the proposed antenna was compared with other monopole antennas in relation to the received power level. A digital TV receiver was used to verify system performance in a closed and urban environment.
O sistema de recepção da TV digital apresenta diversas mudanças tecnológicas na sua arquitetura. Uma das mudanças, é a alteração da faixa de transmissão do VHF para o UHF. Esse fato impõe uma alteração no desenho, tamanho e características radio elétricas da antena no lado do receptor. Dentre as características desejadas de uma antena que opere nessa faixa de frequências está a ominidirecionalidade, ganho, diretividade e largura de banda elevada para cobrir toda a faixa necessária, aliado a um baixo custo e facilidade de construção. Esta pesquisa apresenta uma nova proposta de antena, composta por um monopolo planar como elemento irradiador, e suportado por uma estrutura em formato de tronco de cone unida a um elemento cilíndrico em forma de luva para promover aumento e controle da largura de banda necessários para cobrir toda a faixa do UHF, inclusive as bandas GSM850, e GSM900. A antena proposta foi projetada com simulador de campo eletromagnético de onda completa. Um protótipo foi simulado e construído e os resultados experimentais demonstraram que a antena pode cobrir a faixa de 469,6 MHz a 1387,4 MHz, com uma taxa de onda estacionária inferior a 2. O desempenho da antena proposta foi comparada com outras monopolos em relação ao nível de potência recebido. Um receptor de TV digital foi utilizado para verificar o desempenho do sistema em um ambiente fechado e urbano.

A arquitetura contemporânea vive hoje uma arriscada fusão com a publicidade e a indústria do entretenimento. Tal convergência exige uma expansão da forma arquitetônica até o limite de sua materialidade. Em busca da renda informacional máxima, característica do universo das marcas mundiais, constatamos uma inversão de seus antigos fundamentos construtivos e produtivos, subvertidos por um jogo de volumes e efeitos para além de qualquer regra ou limitação. Aliado às técnicas digitais de projeto e à reorganização dos canteiros de obra, esse novo fetichismo da forma, análogo à autonomização do poder e da riqueza abstrata no capitalismo contemporâneo, define a nova condição da arquitetura. Estudaremos essa condição tomando como fio condutor projetos dos arquitetos mais consagrados pelo atual sistema de distinção e premiação. No propósito de melhor identificar esta arquitetura da exceção, investigamos nas obras emblemáticas dos últimos vinte anos um conjunto de particularidades e recorrências, que a nosso ver define a economia política da exceção e da regra no mundo atual. Principiamos pela análise do emaranhado de significados que sustentam hoje a forma construída, passando em seguida à esfera da produção das novas modalidades de projeto digital às transformações no canteiro de obras para, ao fim, examinar como ocorrem a circulação (com a proliferação de imagens midiáticas), o consumo (especialmente por meio da indústria do turismo) e a distribuição de riquezas que essa arquitetura favorece. O que se verifica é uma produção sobredeterminada pela busca da renda monopolista derivada das propriedades intrínsecas da forma, em seu novo estágio de concepção e realização. Esperamos, assim, mostrar como a arquitetura de ponta tornou-se uma das manifestações mais expressivas da acumulação flexível e da renda das marcas sob a dominância da lógica das finanças.
Contemporary architecture is dangerously enmeshed with the entertainment industry and the field of advertising. This meshing has pushed architectural form to the limits of materiality. Architecture today searches for maximum informational rent, a process typical of global product branding; through this process, established building and production principles are subverted by a play of volumes and effects beyond any rule or limitation. Relying on digital design technologies and the reorganization of the building site, this new fetishism of form, analogous to the autonomization of power and abstract wealth in contemporary capitalism, defines the new condition of architecture. We study this condition by focusing on the work of those architects who are most successful in the current system of professional recognition and rewards. So as to identify this architecture of exception more precisely, we analyze emblematic works from the last twenty years; in these works we identify a set of particularities and recurrent issues that define the political economy of exception and rule today. We begin by analyzing the tangle of meanings associated with contemporary built form. We then move on to the sphere of production from the new technologies of digital design to transformations in the building site. Finally, we examine three processes as they relate to contemporary architecture: circulation (through the proliferation of images in the media), consumption (in particular through the tourist industry), and distribution of wealth. Our investigation reveals that architectural production, in its new stage of conception and realization, is overdetermined by the search for monopoly rent through intrinsic properties of form. We argue that cutting-edge architecture has become one of the most expressive manifestations of flexible accumulation and brand revenue under the prevailing logic of financial capitalism.

In this thesis, a planar antenna methodology for receiving digital television signals from terrestrial broadcasting is proposed due to its ultra-wide band, omni-directional radiation, high gain, low cost and small size. In a dipole antenna design, multiple loops are constructed in the proposed antenna. Since each loop corresponds to a specific frequency response, multiple loops can yield the integrated frequency response from coupling all frequency responses of multiple loops to reach an ultra-wide band. In the active antenna design, a dipole antenna integrated with a two-port amplifier through a 75 ohm inset microstrip feed line results in ultra-wide band and high gain. In a vehicular antenna design, a new microstrip Printed Circuit Board (PCB) integrated with an iron stick can lead to great matching impedance while adequately adjusting the length of the microstrip. The proposed vehicular antenna can have S11 below -10dB at the Ultra-High Frequency (UHF), ranging from 470MHz to 860MHz, with an average gain of 1.78dBi. In the monopole antennas with coplanar waveguide feed-in designs, we first develop a monopole antenna with a separate coplanar waveguide feed-in, and then modify the antenna’s etch and gap, resulting in high flexibility in the proposed separate feed-in design. Finally, we propose a design with two slot lines located at both sides of the antenna for coupling current paths, to manipulate the resonant frequency. Additionally, the gain is increased when the back of the signal side is added with a radiation metal strip.

Digital television (DTV) is an advanced technology that enables television stations to provide better pictures and sound quality. It can also offer multimedia service and great interactive capabilities. The date when television goes all digital has changed. In this thesis, we propose a compact planar monopole antenna for DTV applications on the terrestrial television broadcasting. The proposed antenna can be printed on dielectric substrate by using printed circuit board technique. Also, the proposed antenna has good feature owing to its low cost in fabrication and ease of construction. It can be easily placed into a portable device such as notebook or TV box. The proposed monopole antenna which consists of microstrip line and a patch with rectangular slits. The wideband property is achieved by using a ground plane with notch and a slotted plane on the monopole back side. These techniques are used to enhance the impedance-matching of the proposed antenna. The proposed antenna can provide a wide operating bandwidth for DVB-T signal reception in the UHF band. The measured radiation patterns show the good characteristics in the operating frequency bands. Details of the proposed antenna designs, analysis, and experimental results of the constructed prototypes are also included.

Digital platforms have come under intense scrutiny from scholars, policy makers, regulators, and the general public for their immense and yet largely opaque influence on the social and economic sphere. This book advances value-form and social-form directions in Marxian theory, moving beyond mainstream economic reasoning that informs much of the debate. Digital monopoly platforms such as Google and Facebook are analysed in light of their profit seeking behaviour and monetary flows generated primarily through advertising and data commodification. Considering the unity of production and circulation the book argues that outputs are better understood as a collection of different types of social forms shaped by capital (pre, intermediate and final commodities) and as forms of public wealth (Copyleft Free Software, publicly financed science and research). The authors critically engage with Marxian theories that conceptualise user activities as forms of digital labour, with zero-price markets and critical legal theories, as well as with ‘internet exceptionalism’ in various forms. The role of regulation of production, especially of financial markets and monopolies is critically discussed with an empirical analysis of the development of GAFAM companies, Google’s mandatory reporting to the Securities and Exchange Commission, and of digital advertising of Google and Facebook. The book discusses contradictions of the capitalist mode of production, limits of ongoing reform initiatives, and alternatives to the logic of capital and commodity production on digital platforms.

Chapter 4 brings into focus various structural threats to journalism, including monopoly control over media infrastructures, the loss of public interest protections, digital divides, and the “Facebook problem.” It examines how monopolies—from platforms to traditional conglomerates and broadband cartels—threaten the entire news media system. The chapter goes on to provide an overview of why media policy matters for journalism and how different ownership structures affect media content. It then concludes with an in-depth discussion of Facebook’s relationship to journalism and the different schools of thought on how we should rein in monopolies.

Annotation:
The Tunu field is a swamp giant gas field located in the Mahakam Delta, East Kalimantan. Stratigraphically, this field has an anticline structure with three main intervals; Tunu Shallow Zone (TSZ), Fresh Water Zone (FWZ), and Tunu Main Zone (TMZ). Shallow gas reservoirs of TSZ have been produced since 2008, following the production of TMZ in the 1990s. Drilling targets in the shallow gas reservoir decreased significantly due to limited reservoir targets, high inclination wells and a low oil price environment. The utilization of radioactive source logging (density and neutron) on Logging While Drilling (LWD) tools is not recommended to be performed in open hole mode for operational and safety issues (e.g: tool stuck). Thus, LWD Monopole sonic is chosen as a replacement of LWD Neutron-Density logs and helps to differentiate between shallow gas potential and coal lithology which is the main challenge in TSZ at interval depth above 1200 mSS. The methodology utilized sonic semblance (STRA) and compressional slowness (DTc) data at real-time and memory data logs, so early decision can be made in drilling mode. In a gas-bearing reservoir, both semblance and slowness are missing, while in coal it produced strong semblance. In order to differentiate carbonate lithology, additional data, such as cutting, calcimetry, drilling Rate of Penetration and Gas While Drilling are utilized. During 2018-2020, 5 wells have been drilled using LWD Monopole sonic together with LWD GR-Resistivity-Neutron-Density (Triple Combo) to calibrate the fluid interpretation and 3 trial wells with only GR-Resistivity-Monopole Sonic. As a result, LWD Monopole sonic is able to differentiate between Gas and Coal based on semblance and slowness with a success ratio up to 80%. This LWD Monopole Sonic provides a non-radioactive solution for safe and effective logs acquisition for shallow gas identification that could be applied in oil and gas fields outside Mahakam.

Annotation:
In this paper, we study the coexistence of cash and electronic payments introducing some distortions in the payments markets to understand the widespread use of cash, specially in emerging countries. Following Lagos andWright (2005) we model explicitly some frictions in the exchange process considering money as essential. We introduce in this theoretical framework, theft and informality (measured by tax evasion), as factors a ecting cash usage and, therefore competition with an electronic payment method. In this paper, segmentation in the payments market is considered by introducing heterogeneity in the seller's side, assuming di erent levels of productivity to explain the preference for cash or for electronic payments. Considering the above, the provision of the electronic payment platform is modeled under three di erent market structures to identify the e ects of the distortions comparing the results with the social planner solution. In the rst case, the electronic payment platform is provided by a public rm as a free service; in the second case a private monopoly provides the platform at a positive cost, and in the third case the conditions for the existence of a mixed duopoly are derived. The existence of a public provider in the electronic payments market could lead private networks to provide these services at a lower cost than in the monopoly case, increasing the coverage of digital payments and reducing cash usage, which implies gains in social welfare. This paper gives a theoretical basis and key insights to the discussions regarding public provision of new payment services when the market is already served by private suppliers.
