The article is devoted to the problem of improving the reliability of monitoring systems for the technical conditions of high-rise buildings. The improvement is based on string sensors with an impulsed excitation method ensuring the maximum signal-to-noise ratio at their output. The influence of the parameters of the monitoring system on the shape of the excitation impulses of the string, and, consequently, on the amplitude of the string vibration of the string converter is also considered in the article. It has been experimentally proved that the parameters of the excitation impulses of the string converters. The article presents the results of the experiments showing the effect of the fronts duration of the excitation impulses on the amplitude of the oscillations of the strings. The influence of the fronts duration of the excitation impulse with the frontal lengths up to 0.5 ms is studied at the excitation impulse duration not exceeding 0.5 times the duration of natural oscillation periods of the string. The experimental data are compared with the theoretical ones and hypotheses explaining their difference are advanced. The article suggests some methods of reducing the influence of the cable-switching equipment system parameters on the amplitude of string oscillations. The possibilities of improving the reliability of the systems developed on the basis of string sensors with an impulsed excitation method and used for monitoring the technical conditions of the high-rise buildings are proposed.

This article investigated two cases of impulse transformer location selection in the DC-DC type two-step resonant converter, which fully segregates processes of taking and transferring energy between the input and its load. The electromagnetic processes during energy taking/transferring were studied, including active and static losses in the converter elements. Based on the suggested analytical-numerical method, the criteria for selecting the impulse transformer optimal transformation ratio, from the system efficiency point of view, was derived. The proposed optimization technique can be applied to a wide variety of input and output parameters. References 3, Figures 7.

An impulse power supply has been designed, simulated, and tested in order to feed the primary of a high-frequency transformer. Pulse power system has been widely used for plasma applications. The operational principle of the pulse power system is that the energy from the input source is stored in the capacitor bank device through a dc-dc converter. Then, when a discharging signal is given, the stored energy is released to the load. The new family of ZCS converters is suitable for high-power applications using insulated gate bipolar transistors (IGBTs). The power converter can achieve zero switching with the aid of high-frequency transformer. The device is capable of charging a 0.1 μF capacitor up to 5 kV which accounts for a charging power of 5 kJ/s. The novel control algorithm is achieved which eminently considers the nonlinear control characteristics of impulse power supply. The required charging voltage, together with the constraint on the charging time, translates into a required maximum power of 10 kW reduced in this initial version to 5 kW. The difficulty to reliably control such a power at the high-voltage side practically forbids any approach featuring a more or less stabilized DC high-voltage to be generated from a conventional 50 Hz transformer through rectification.

Compressive Sensing (CS) Theory enables sampling discrete signals with quite lower sampling rate compared with traditional Nyquist sampling rate and guaranteeing faithful reconstruction. Based on CS theory, Analog-to-Information Conversion (AIC) was proposed to process continuous-time signal. In this paper, the framework of Analog-to-Information Converter is composed by a pseudo-random demodulator, a low pass analog filter and a low speed sampler. And we mainly discuss the damage on the signal recovery produced by lower and higher orders of filter impulse response.

Abstract In the article “Technological capabilities of impulse rotators” the results of use of impulse rotators in some technological processes, differential adjustment of their motion with kinematic and dynamic vibration exciter are considered. Equation of kinetic energy of impulse rotator allows to determine mutual influence of design elements on rational use of supplied pulse energy for useful work. Positive qualities of kinematic torsional vibration exciters are noted, the main of which is organization of force pulse regularity and its considerable force possibilities of pulse creation. A generalized graph of the change of productivity and wear of the working element of the pulse converter compared to the static one is given. Features of impulse rotators with kinematic excitation of torsional oscillations make it possible to change the mode of work performance, to apply low-energy processes of individual operations. Transportation way of destruction products by the screw with use of an impulse rotator on breeds above average fortress excludes use of the compressor. Machines with rolling and spring impact tools do not correspond to the screw method of destruction products discharge and require compressor use. In this case, the energy intensity of production unit increases more than twice.

AssociaÃÃo TÃcnico-CientÃfica Eng. Paulo de FrontinThis paper presents the study and development of a voltage impulse generator using a cascaded boost converter topology operating in Discontinuous Conduction Mode (DCM) which will be used for the inspection of grounding systems used by electric power companies. The output voltage of the converter is applied to the grounding system which behaves as a load. The signal applied to the ground was measured by the data acquisition system and analyzed by an intelligent algorithms software. The voltage has the characteristics of a double exponential waveform which is a mathematical model used for study of lightning. Furthermore, the impulse generator has the option to produce a square waveform output voltage. Unlike, the traditional impulse generator with spark gaps, which was disadvantages of poor lifetime and the need of external system to operating the same, the developed generator uses only semiconductor devices in its construction. A theoretical study was carried out through qualitative and quantitative analyzes moreover, the switching process and the losses in the converter components were studied. In this work was performed the design of a cascaded boost converter for evaluating grounding systems with approximated 156 W, input voltage of 110 Vac rms and an output peak voltage of approximately 880 VDC, which correspond to the sum each voltage capacitor of the boost converter, when they are connected in series. A prototype with the indicated specifications was implemented and experimentally tested in the laboratory and real conditions using four grounding systems configurations. Tests were performed considering that the grounding impedance is resistive. The obtained experimental and simulation results are used to validate the theoretical analysis and the designed converter.
Este trabalho apresenta o estudo e desenvolvimento de um gerador de impulsos de tensÃo usando a topologia de um conversor boost em cascata operando em Modo de ConduÃÃo DescontÃnua (MCD) que serà utilizado para inspeÃÃo de sistemas de aterramentos usados pelas concessionÃrias de energia elÃtrica. A tensÃo obtida na saÃda do conversor à aplicada ao sistema de aterramento que se comporta como uma carga. O sinal aplicado ao aterramento à medido pelo sistema de aquisiÃÃo de dados e analisado pelo software por algoritmos inteligentes. A tensÃo aplicada tem as caracterÃsticas de uma onda tipo dupla exponencial que à um modelo matemÃtico para estudo de descargas atmosfÃricas. AlÃm disso, o gerador poderà gerar tensÃes com caracterÃsticas de uma onda quadrada. O gerador de impulsos desenvolvido utiliza apenas dispositivos semicondutores na sua construÃÃo que apresentam as vantagens de possuir uma longa vida Ãtil, podem operar em altas frequÃncias, sÃo acionados com baixa tensÃo e possuem uma baixa queda de tensÃo ao contrÃrio dos tradicionais geradores de impulsos que utilizam os spark gaps para chaveamento que apresentam como desvantagens a baixa vida Ãtil e a necessidade de um sistema externo para funcionamento da mesma. Um estudo teÃrico foi realizado atravÃs das anÃlises qualitativa e quantitativa, alÃm das anÃlises do processo de comutaÃÃo e das perdas nos componentes do conversor. Neste trabalho foi realizado o projeto do conversor boost em cascata para inspeÃÃo de sistemas de aterramento com uma potÃncia aproximada de 156 W, tensÃo de entrada eficaz de 110 Vca e tensÃo de pico de aproximadamente 880 Vcc que corresponde à soma da tensÃo dos capacitores do conversor boost quando estÃo dispostos em sÃrie. Um protÃtipo com as especificaÃÃes indicadas foi construÃdo e testado experimentalmente em laboratÃrio e em campo utilizando quatro topologias de sistemas de aterramento. Foram realizados testes considerando que a impedÃncia de aterramento era puramente resistiva. Os resultados de simulaÃÃo e experimentais obtidos sÃo utilizados para validar a anÃlise teÃrica e o projeto realizado.

The dissertation deals with designing electromechanical impulse induction converters (EIIC) with liquid-nitrogen-cooled cryoresistive windings. On the basis of generalization of accumulated data in impulse electromechanics, a technique for designing cryogenic EIICs has been developed which takes into account interrelated electrical, magnetic, thermal, and mechanical complex processes with nonlinear critical parameters. The basic mechanisms of power and energy EIIC functioning which result in linear motion of the armature when the converter is excited from a capacitive accumulator or a constant-voltage source have been revealed. Structure-geometry, circuit, and design approaches for perfecting single- and multi-stage EIICs with valid parameters have been suggested. Experimental data have been obtained to validate developed mathematical models and engineering solutions. The main research results have been utilized and implemented at execution of seven state and commercial research projects, in research enterprises, and for students’ training.

Unlike, the traditional impulse generator with spark gaps, which was disadvantages of poor lifetime and the need of external system to operating the same, the developed generator uses only semiconductor devices in its construction. A theoretical study was carried out through qualitative and quantitative analyzes moreover, the switching process and the losses in the converter components were studied. In this work was performed the design of a cascaded boost converter for evaluating grounding systems with approximated 156 W, input voltage of 110 Vac rms and an output peak voltage of approximately 880 VDC, which correspond to the sum each voltage capacitor of the boost converter, when they are connected in series. A prototype with the indicated specifications was implemented and experimentally tested in the laboratory and real conditions using four grounding systems configurations. Tests were performed considering that the grounding impedance is resistive. The obtained experimental and simulation results are used to validate the theoretical analysis and the designed converter
Este trabalho apresenta o estudo e desenvolvimento de um gerador de impulsos de tensão usando a topologia de um conversor boost em cascata operando em Modo de Condução Descontínua (MCD) que será utilizado para inspeção de sistemas de aterramentos usados pelas concessionárias de energia elétrica. A tensão obtida na saída do conversor é aplicada ao sistema de aterramento que se comporta como uma carga. O sinal aplicado ao aterramento é medido pelo sistema de aquisição de dados e analisado pelo software por algoritmos inteligentes. A tensão aplicada tem as características de uma onda tipo dupla exponencial que é um modelo matemático para estudo de descargas atmosféricas. Além disso, o gerador poderá gerar tensões com características de uma onda quadrada. O gerador de impulsos desenvolvido utiliza apenas dispositivos semicondutores na sua construção que apresentam as vantagens de possuir uma longa vida útil, podem operar em altas frequências, são acionados com baixa tensão e possuem uma baixa queda de tensão ao contrário dos tradicionais geradores de impulsos que utilizam os spark gaps para chaveamento que apresentam como desvantagens a baixa vida útil e a necessidade de um sistema externo para funcionamento da mesma. Um estudo teórico foi realizado através das análises qualitativa e quantitativa, além das análises do processo de comutação e das perdas nos componentes do conversor. Neste trabalho foi realizado o projeto do conversor boost em cascata para inspeção de sistemas de aterramento com uma potência aproximada de 156 W, tensão de entrada eficaz de 110 Vca e tensão de pico de aproximadamente 880 Vcc que corresponde à soma da tensão dos capacitores do conversor boost quando estão dispostos em série. Um protótipo com as especificações indicadas foi construído e testado experimentalmente em laboratório e em campo utilizando quatro topologias de sistemas de aterramento. Foram realizados testes considerando que a impedância de aterramento era puramente resistiva. Os resultados de simulação e experimentais obtidos são utilizados para validar a análise teórica e o projeto realizado

This work deals with high power pulse converters (tens of kW) using new semiconductor devices of silicon carbide (SiC). Firstly the current state of the issue is analyzed. A research in a specific area of high power buck converters with pulse transformer follows. There was a strong emphasis on minimizing size and weight. The design process was focused also on reliability and robustness. To achieve the defined objectives, it was necessary to use the latest available switching transistors and diodes, and an unusually high switching frequency (100 kHz at a power of about 16 kW). Due to the high switching frequency, we achieved small size of pulse transformers and output chokes. An optimization of high-frequency pulse transformer with demand on minimum volume and weight of core and windings represents a separate theoretical part of the thesis. There have been proposed several analytical solutions of optimization problems, the results of which could overlap with the implementation in practice of switching power supplies. The combination of high switching frequency, fast semiconductors and the high power brings various parasitic effects to the power circuit. In the thesis, these parasitic effects are analyzed. Solutions which minimize or completely remove those effects were theoretically designed and successfully implemented, tested and finalized in experimental part of the work. Detailed description of the implementation of functional sample and series of validation measurements are included in the final part.

This work is concerned with power inverters for alternate high voltage power sources. The theoretical part describes the topology of inverters that can be used in alternate power sources. A model of voltage transformer is described in details to better understand the parasitic effects that are inevitably present in high voltage power sources and, therefore, have to be taken into consideration at the design of high voltage power sources. The work is oriented to problems of alternate high voltage power sources for ozone generators. This is the reason, why the theoretical and, partially, also the experimental part deal with the properties of ozone and its use. The experimental part solves high voltage inverter with capacitive load that is formed by discharge element of an ozone generator. Designed inverter is able to feed the capacitive load with high voltage at very short periods of time from several microseconds up to tens of nanoseconds. In comparison with the length of voltage pulses in common ozone generators, this pulses are more than 100-time shorter. This has a positive effect to silent discharge characteristics.

The thirteenth century brought new urgency to Catholic efforts to convert non-Christians, and no Catholic ruler was more dedicated to this undertaking than King Louis IX of France. His military expeditions against Islam are well documented, but there was also a peaceful side to his encounter with the Muslim world, one that has received little attention until now. This book shines new light on the king's program to induce Muslims to voluntarily convert to Christianity and resettle in France. It recovers a forgotten but important episode in the history of the Crusades while providing a rare window into the fraught experiences of the converts themselves. This book transforms our understanding of medieval Christian–Muslim relations by telling the stories of the Muslims who came to France to live as Christians. Under what circumstances did they willingly convert? How successfully did they assimilate into French society? What forms of resistance did they employ? In examining questions like these, the book weaves a richly detailed portrait of a dazzling yet violent age whose lessons still resonate today. Until now, scholars have dismissed historical accounts of the king's peaceful conversion of Muslims as hagiographical and therefore untrustworthy. This book takes these narratives seriously, and uncovers archival evidence to back them up. It brings these findings to life; setting them in the context of the Seventh Crusade and the universalizing Catholic impulse to convert the world.

El Partido Demócrata Cristiano ha sido una pieza clave en la más general inserción de la política chilena en las grandes tendencias político-ideológicas que dominaron la segunda mitad del siglo XX. Durante el siglo pasado las relaciones entre actores políticos externos y chilenos se enmarcaron en el contexto de grandes procesos y disyuntivas de relevancia mundial: la Guerra Fría y la más general competencia entre proyectos sociales holísticos, la emergente preocupación por los derechos humanos, la experiencia de las transiciones post dictatoriales en Europa Meridional, entre otros. Estos actores externos jugaron un papel muy relevante en impulsar la estrategia política de salida de la dictadura chilena que, al converger con factores internos, tuvieron un impacto importante en determinar los lineamientos de la transición. Los actores políticos locales, como el PDC, lejos de ser piezas en manos de referentes externos, tuvieron un papel protagónico, usando sus redes internacionales para afianzar y consolidar su proyecto político. A diferencia de otros trabajos que han abordado la dimensión internacional de la transición, el foco de este libro no son los aspectos económicos, ni los ideológicos, sino más bien la centralidad política de un actor, el Partido Demócrata Cristiano, y la capacidad que éste tuvo de consolidar a nivel internacional su posición de referente para el retorno a la democracia en Chile.

Disaffected Parties reveals how alienation from politics effected crucial changes to the shape and status of literary form. Recovering the earliest expressions of grumbling, irritability, and cynicism towards politics, this study asks how unsettled partisan legacies converged with more recent discontents to forge a seminal period in the making of English literature—and thereby poses wide-ranging questions about the lines between politics and aesthetics. Reading works including Laurence Sterne’s Tristram Shandy, James Boswell’s Life of Johnson, the novels of Maria Edgeworth and Jane Austen, and the satirical poetry of Lord Byron in tandem with print culture and partisan activity, this book shows how these writings remained animated by disaffected impulses and recalcitrant energies at odds with available party positions and emerging governmental norms—even as they sought to imagine perspectives that looked beyond the divided political world altogether. ‘No one can be more sick of—or indifferent to politics than I am’, Lord Byron wrote in 1820. Between the later eighteenth century and the Romantic age, disaffected political attitudes acquired increasingly familiar shapes. Yet this was also a period of ferment in which unrest associated with the global age of revolutions (including a dynamic transatlantic opposition movement) collided with often inchoate assemblages of parties and constituencies. As writers adopted increasingly emphatic removes from the political arena and cultivated familiar stances of cynicism, detachment, and retreat, their estrangement also promised to loop back into political engagement—and to make their works ‘parties’ all their own.

Desde que la entrevista se consolidó como género periodístico, la tarea del periodista fue simplemente conversar con el entrevistado para luego volcar sus declaraciones en estructuras y presentaciones bastante encasilladas: estilo directo, indirecto o mixto. Catorce amapolas. Reflexiones (prismáticas) sobre la creación artística, nace como fruto no sólo de romper con estos cánones escriturales sino también con la necesidad de aportar un nuevo enfoque a los trabajos que existen en Argentina sobre las realizaciones artísticas. Nada hay más representativo que la propia voz del creador refiriéndose a su obra para reflexionar sobre el proceso de construcción. El libro parte de 14 reuniones presenciales transformadas en relatos biográficos en el que la modalidad subjetiva es el rasgo que lo distingue de la mayoría de los estudios y publicaciones existentes. El reto que impuso fue un cambio en la mirada sobre el artista y sus relaciones con el mundo, incluyéndolo como parte interactuante, como ser que siente y sobre todo que lo re-crea desde su propia producción. Utilizando la entrevista como medio de contacto para obtener información, se fundó un laboratorio dialógico que permitió referir al proceso de creación. Sin embargo, no solo fueron meses de escucha a artistas de diferentes ramas o disciplinas para conocer sus abordajes, lenguajes, técnicas, herramientas e interpelaciones sino que luego se hizo un cuidadoso trabajo para darle un tono autobiográfico y en primera persona. Cada encuentro realizado por separado con los catorce artistas fue único. Bajo el supuesto de que los testimonios y las entrevistas se consideran un “lugar” para la construcción del conocimiento, esta publicación partió del interrogante de si es posible encontrar la presencia de un método en su creación. Cada diálogo tuvo su propia cadencia, rozó temas puntuales y obras específicas, adquirió su propio lenguaje de entendimiento y dio un marco espaciotemporal para que los testimonios reflexionen sobre su propio camino compositivo. En las siguientes páginas, y en cada sección particular, el lector podrá encontrarse con las reflexiones de artistas de diferentes ramas y lenguajes estéticos en relación a la creación. Partiendo del interrogante general de si es posible hablar de la presencia de un método en la composición, cada testimonio recurre a su propia historia y retrospectiva para mencionar disparadores, intereses, motivaciones, recursos y contextos influyentes en diversas obras y producciones.

Due to special operating conditions, the valve side bushing of the converter transformer connected to the converter valve is subject to complex voltage excitation, including DC voltage, AC/DC composite voltage, lightning impulse overvoltage, or composite voltage of operating overvoltage and DC. Under the action of this complicated electric field, the oil-paper insulation of the valve-side bushing of the converter transformer is prone to electric field distortion due to charge accumulation, which causes a surface discharge, which will seriously cause the edge breakdown. At the same time, since the temperature in the converter transformer rises due to a large amount of loss during the operation of the transformer, creeping discharge is more likely to occur under the electrothermal composite field. Hence, it is significant to carry out research on the surface discharge characteristics of the oil-paper insulation on the valve side of the converter transformer under the electrothermal composite field.

The concluding chapter provides summary observations of the book’s themes that highlight the complex, multifaceted dimension of conversion throughout twenty centuries of Christian history. These include the convert’s cognizance of divine presence; the crucial importance of historical context (political, religious, institutional, and socioeconomic factors); continuity and discontinuity (how much of the new displaces the old in conversion?); nominal, incomplete, and “true” conversions; personal testimonies and narratives (the autobiographical impulse attests to the converted life); the role of gender; identity and the self; agency (are converts actors or are they being acted upon?); the mechanisms behind and the motivations for conversion; the body as a site of conversion; the role of music; conversion as event and process; coercive practices; and forms of communication in the converting process.

This chapter investigates the broader global context that generated the nineteenth-century missionary revival, which laid the foundation for missionary organizations like the Protestant Berlin Missionary Society (BMS) and the Catholic Society of the Divine Word (SVD). Witnessing the rise of revolutionary anti-clerical forces swell in the late eighteenth century, the founders of both missionary societies lived during a period of deep anxiety about the fate of Christianity. Missionary leaders channeled these anxieties. They recruited pious young men and sent them across the globe with the hopes of winning new converts as a way to combat the forces of secularism. This chapter argues that anxiety and optimism formed the dual pillars that propped up the nineteenth- century German missionary mind.

In this paper reduce power of multichannel fractional sample rate convertor by minimized hamming distance between consecutive coefficients of filter using Genetic algorithm. The main component of multichannel fractional sample rate convertor is Cascaded multiple architecture finite impulse response filter (CMFIR filter). CMFIR is implemented by cascading of cascaded integrator-comb (CIC) & multiply accumulate architecture (MAC) FIR filter. Genetic algorithm minimizes the hamming distance between consecutive coefficients of CMFIR filter. By Minimizing the hamming distance of consecutive filter coefficient reduces the transaction from 0 to 1 or 1 to 0. These techniques reduce the switching activity of CMOS transistor which is directly reduces Dynamic power consumption by multichannel sample rate convertor, it also minimizes the total power consumption of multichannel fractional sample rate convertor. later than use genetic algorithm on 1 to 128 channel Down sample rate convertor total power reduced by 3.44% to 61.56%, dynamic power reduced by 9.09% to 56.25% .1 to 128 channel Up sample rate convertor total power reduced by 2.81% to 45.42%, dynamic power reduced by 4.76% to 56%, 1 to 128 channel fractional sample rate convertor total power reduced by 1.44% to 17.17%, dynamic power reduced by 6.25% to 19.92%.

We have discussed so far the decimation and interpolation where the sampling rate conversion factor is an integer. However, the need for a non-integer sampling rate conversion appears when the two systems operating at different sampling rates have to be connected, or when there is a need to convert the sampling rate of the recorded data into another sampling rate for further processing or reproduction. Such applications are very common in telecommunications, digital audio, multimedia and others. In this chapter, we consider the sampling rate conversion by a rational factor, called sometimes a fractional sampling rate conversion. We use MATLAB functions from the Signal Processing and Filter Design Toolbox to demonstrate the fractional sampling rate conversion. We present the technique for constructing efficient fractional sampling rate converters based on FIR filters and the polyphase decomposition. In the sequel, we consider the sampling rate alteration with an arbitrary conversion factor. We present the polynomial-based approximation of the impulse response of a hybrid analog/digital model, and the implementation based on the Farrow structure. We also consider the fractional-delay filter problem. This chapter concludes with MATLAB exercises for individual study.

George Whitefield’s innovative doctrine of the Holy Spirit as an indwelling principle proved to be a perplexing issue for may Congregationalists. Part 3 tells the story of one man’s struggle to discern its presence in the body of a young Boston revival convert named Martha Robinson. Through a close inspection of physical signs and verbal utterances, Hartford magistrate Joseph Pitkin found that Robinson’s body had been alternately conscripted by Satan and the Holy Spirit. His surprising discovery positions the phenomenon of ecstatic Spirit possession at the heart of the Whitefieldian new birth experience. During the revivals of the 1740s, New Englanders learned to associate the descent of the Holy Spirit with exercised bodies, impulsive biblical texts, and unusual visionary phenomena.

This chapter introduces “the Living Stations of the Cross,” a Black Catholic reenactment of the passion and death of Jesus performed annually by parishioners of Chicago’s largest Black Catholic church from 1937 to 1968. This devotional practice serves as a lens through which to better understand the ways in which Catholic ritual life and relationships distinguished Catholic converts from the Protestant churches proliferating around them in the midst of the Great Migrations. It argues that Black Catholics should be understood as sharing in the same impulse as other new religious movements or “religio-racial movements,” such as the Black Hebrews and Black Muslims, who adopted religious practices and bodily disciplines that marked them as different from the assorted Black evangelical practices that were quickly coming to be understood as normative for Black religious life (known by the shorthand “the Black Church”).

Chapter 1 charts the institutionalization of confessional difference in the Russian Empire, from Tsar Alexander I and the genesis of confessional choice for Jews in 1817, to freedom of conscience measures instituted by Tsar Nicholas II in the wake of the 1905 revolution, which allowed Jewish converts to all tolerated confessions to legally reclaim their ancestral faith. The chapter uses the 1820 conversion to Catholicism of Moshe Schneerson, scion to the Chabad Hasidic dynasty, to illustrate the conditions in pre-reform imperial Russia (1817-1855) that shaped the conversion landscape for Jews. The tsarist state’s missionary impulse was tempered by religious toleration and the empire’s increasing patronage and sponsorship of a variety of Christian and non-Christian religions. The Schneerson case also highlights how contemporary Jews actively engaged with the problem of Jewish conversion and leveraged their confessional status to vie with the state for control over apostasy and communal belonging.

Many theories try to explain why remote controls of asylum seekers proliferated in the 1980s and 1990s, but most techniques of remote control were developed in the 1930s and 1940s. Policies to push out the border were ad hoc responses to perceived crises that then spread as governments copied each other’s policies. Europeanization took this process toward convergence the furthest of all the cases. Over time, policies have tended to converge across the Global North as multiple forces, such as the end of the Cold War and the broadening of the refugee definition, incentivized further remote control. This chapter describes the broad factors that promoted the spread of remote control as well as where those impulses have been constrained by countervailing forces arising from the courts, transnational advocacy networks, and foreign policy interests.

The extraction of wave energy through self-rectifying air turbine is one of the emerging technologies for oscillating water column (OWC) based wave energy devices. In the present effort, a bi-directional impulse (BDI) turbine is designed and the performance parameters were found numerically and compared with an existing unidirectional impulse (UDI) turbine. A brief analytical formulation through similarity laws, to find a dynamically similar BDI turbine using pressure drop vs flow characteristics, gives the approximate diameter range equivalent to the reference UDI turbine. The results are used to reduce the range of diameters and it is found that the characteristics are matching with the reference UDI turbine. The maximum and minimum diameters among the selected range are considered for detailed computational fluid dynamics (CFD) analysis. These two BDI turbines are modeled and meshed in ICEM CFD 14.5. The commercial CFD code CFX 14.5 is used for the numerical simulations. The Reynolds-averaged Navier-Stokes (RANS) equations with the standard k-ϵ scalable wall function model are solved to obtain the performance parameters. A detailed flow physics of the BDI turbines has also been included.

¿Sabías que la migración impulsa el crecimiento y la capacidad de innovación de los países? América Latina y el Caribe enfrenta un fenómeno migratorio sin precedentes. De los casi 15 millones de migrantes en la región más de la mitad han dejado sus países en los últimos 5 años, debido a situaciones de inestabilidad política, social y económica, desastres naturales y el COVID-19. Desde el Laboratorio de Innovación (BID Lab) y la Unidad de Migración del BID creemos que este desafío demanda una participación más activa y novedosa del sector privado y la sociedad civil, que permita crear nuevas oportunidades al unir el crecimiento económico y social que genera la migración con la capacidad de innovación, creatividad y emprendimiento que caracteriza a estos sectores y a los migrantes. Este enfoque, que llamamos MIGnnovación, busca apoyar los esfuerzos del sector público, aprovechar el talento de las personas, las nuevas tecnologías y la construcción de alianzas para convertir esta realidad en una gran oportunidad de desarrollo inclusivo para nuestros países. Conoce en esta publicación datos, historias e iniciativas exitosas que demuestran el poder de la MIGnnovación para hacer frente al desafío migratorio, y así seguir en nuestra tarea de mejorar la vida de millones.
