湾岸およびインド洋地域の安全保障と日本

In this paper, first we look back at the activities of the JMSDF in the Indian Ocean and the Gulf for the past 10-20 years from the view-point of contributions to security in the regions, and Japan's defence and diplomatic policies. In addition we would like to consider the situation that Japan has currently been placed in, or the primary factors of the change of power balance caused by China's foreign expansion and US gradual troop reductions, and economic conditions and energy supply problems after the earthquake disaster, as well as the returning of the LDP Administration. Each of these affects Japan's defence and diplomatic policies, and Japanese approach to Gulf countries is to be precisely understood in this context. For Japan, the importance of relationships with Gulf countries will surely increase in the foreseeable future. However the immediate addition of the JMSDF's force in the Indian Ocean and the Gulf Region is difficult. So Japan's role in regional security will probably be depending on the licensing of technology to India and Gulf countries, plus the construction of collaborative systems devoted to the training and support of highly proficient personnel. China will have a competitive relationship with Japan over access to the energy supply sources and the markets in Gulf countries, and it will be necessary to employ such systems for the purpose of international trust building and preventing of any free-ride.

Use of STATCOM in wind farms with fixed-speed generators for grid code compliance

The increasing penetration of wind energy into power systems has pushed grid operators to set new requirements for this kind of generating plants in order to keep acceptable and reliable operation of the system. In addition to the low voltage ride through capability, wind farms are required to participate in voltage support, stability enhancement and power quality improvement. This paper presents a solution for wind farms with fixed-speed generators based on the use of STATCOM with braking resistor and additional series impedances, with an adequate control strategy. The focus is put on guaranteeing the grid code compliance when the wind farm faces an extensive series of grid disturbances.

Dynamic Response Optimization of Vehicles through Efficient Multibody Formulations and Automatic Differentiation Techniques

El diseño y desarrollo de sistemas de suspensión para vehículos se basa cada día más en el diseño por ordenador y en herramientas de análisis por ordenador, las cuales permiten anticipar problemas y resolverlos por adelantado. El comportamiento y las características dinámicas se calculan con precisión, bajo coste, y recursos y tiempos de cálculo reducidos. Sin embargo, existe una componente iterativa en el proceso, que requiere la definición manual de diseños a través de técnicas “prueba y error”. Esta Tesis da un paso hacia el desarrollo de un entorno de simulación eficiente capaz de simular, analizar y evaluar diseños de suspensiones vehiculares, y de mejorarlos hacia la solución optima mediante la modificación de los parámetros de diseño. La modelización mediante sistemas multicuerpo se utiliza aquí para desarrollar un modelo de autocar con 18 grados de libertad, de manera detallada y eficiente. La geometría y demás características de la suspensión se ajustan a las del vehículo real, así como los demás parámetros del modelo. Para simular la dinámica vehicular, se utiliza una formulación multicuerpo moderna y eficiente basada en las ecuaciones de Maggi, a la que se ha incorporado un visor 3D. Así, se consigue simular maniobras vehiculares en tiempos inferiores al tiempo real. Una vez que la dinámica está disponible, los análisis de sensibilidad son cruciales para una optimización robusta y eficiente. Para ello, se presenta una técnica matemática que permite derivar las variables dinámicas dentro de la formulación, de forma algorítmica, general, con la precisión de la maquina, y razonablemente eficiente: la diferenciación automática. Este método propaga las derivadas con respecto a las variables de diseño a través del código informático y con poca intervención del usuario. En contraste con otros enfoques en la bibliografía, generalmente particulares y limitados, se realiza una comparación de librerías, se desarrolla una formulación híbrida directa-automática para el cálculo de sensibilidades, y se presentan varios ejemplos reales. Finalmente, se lleva a cabo la optimización de la respuesta dinámica del vehículo citado. Se analizan cuatro tipos distintos de optimización: identificación de parámetros, optimización de la maniobrabilidad, optimización del confort y optimización multi-objetivo, todos ellos aplicados al diseño del autocar. Además de resultados analíticos y gráficos, se incluyen algunas consideraciones acerca de la eficiencia. En resumen, se mejora el comportamiento dinámico de vehículos por medio de modelos multicuerpo y de técnicas de diferenciación automática y optimización avanzadas, posibilitando un ajuste automático, preciso y eficiente de los parámetros de diseño. ABSTRACT Each day, the design and development of vehicle suspension systems relies more on computer-aided design and computer-aided engineering tools, which allow anticipating the problems and solving them ahead of time. Dynamic behavior and characteristics are thus simulated accurately and inexpensively with moderate computational times and resources. There is, however, an iterative component in the process, which involves the manual definition of designs in a trialand-error manner. This Thesis takes a step towards the development of an efficient simulation framework capable of simulating, analyzing and evaluating vehicle suspension designs, and automatically improving them by varying the design parameters towards the optimal solution. The multibody systems approach is hereby used to model a three-dimensional 18-degrees-of-freedom coach in a comprehensive yet efficient way. The suspension geometry and characteristics resemble the ones from the real vehicle, as do the rest of vehicle parameters. In order to simulate vehicle dynamics, an efficient, state-of-the-art multibody formulation based on Maggi’s equations is employed, and a three-dimensional graphics viewer is developed. As a result, vehicle maneuvers can be simulated faster than real-time. Once the dynamics are ready, a sensitivity analysis is crucial for a robust optimization. To that end, a mathematical technique is introduced, which allows differentiating the dynamic variables within the multibody formulation in a general, algorithmic, accurate to machine precision, and reasonably efficient way: automatic differentiation. This method propagates the derivatives with respect to the design parameters throughout the computer code, with little user interaction. In contrast with other attempts in the literature, mostly not generalpurpose, a benchmarking of libraries is carried out, a hybrid direct-automatic differentiation approach for the computation of sensitivities is developed, and several real-life examples are analyzed. Finally, a design optimization process of the aforementioned vehicle is carried out. Four different types of dynamic response optimization are presented: parameter identification, handling optimization, ride comfort optimization and multi-objective optimization; all of which are applied to the design of the coach example. Together with analytical and visual proof of the results, efficiency considerations are made. In summary, the dynamic behavior of vehicles is improved by using the multibody systems approach, along with advanced differentiation and optimization techniques, enabling an automatic, accurate and efficient tuning of design parameters.

Aerodynamic shape optimization of the nose of a high-speed train subjected to crosswind conditions

When dealing with the design of a high-speed train, a multiobjective shape optimization problem is formulated, as these vehicles are object of many aerodynamic problems which are known to be in conflict. More mobility involves an increase in both the cruise speed and lightness, and these requirements directly influence the stability and the ride comfort of the passengers when the train is subjected to a side wind. Thus, crosswind stability plays a more relevant role among the aerodynamic objectives to be optimized. An extensive research activity is observed on aerodynamic response in crosswind conditions.

50 Years Ago We Marched: What began on the grounds of Lincoln University, ended on the steps of the Alabama State Capitol

LINCOLN UNIVERSITY - On March 25, 1965, a bus loaded with Lincoln University students and staff arrived in Montgomery, Ala. to join the Selma march for racial and voting equality. Although the Civil Rights Act of 1964 was in force, African-Americans continued to feel the effects of segregation. The 1960s was a decade of social unrest and change. In the Deep South, specifically Alabama, racial segregation was a cultural norm resistant to change. Governor George Wallace never concealed his personal viewpoints and political stance of the white majority, declaring “Segregation now, segregation tomorrow, segregation forever.” The march was aimed at obtaining African-Americans their constitutionally protected right to vote. However, Alabama’s deep-rooted culture of racial bias began to be challenged by a shift in American attitudes towards equality. Both black and whites wanted to end discrimination by using passive resistance, a movement utilized by Dr. Martin Luther King Jr. That passive resistance was often met with violence, sometimes at the hands of law enforcement and local citizens. The Selma to Montgomery march was a result of a protest for voting equality. The Student Nonviolent Coordinating Committee (SNCC) and the Southern Christian Leadership Counsel (SCLC) among other students marched along the streets to bring awareness to the voter registration campaign, which was organized to end discrimination in voting based on race. Violent acts of police officers and others were some of the everyday challenges protesters were facing. Forty-one participants from Lincoln University arrived in Montgomery to take part in the 1965 march for equality. Students from Lincoln University’s Journalism 383 class spent part of their 2015 spring semester researching the historical event. Here are their stories: Peter Kellogg “We’ve been watching the television, reading about it in the newspapers,” said Peter Kellogg during a February 2015 telephone interview. “Everyone knew the civil rights movement was going on, and it was important that we give him (Robert Newton) some assistance … and Newton said we needed to get involve and do something,” Kellogg, a lecturer in the 1960s at Lincoln University, discussed how the bus trip originated. “That’s why the bus happened,” Kellogg said. “Because of what he (Newton) did - that’s why Lincoln students went and participated.” “People were excited and the people along the sidewalk were supportive,” Kellogg said. However, the mood flipped from excited to scared and feeling intimidated. “It seems though every office building there was a guy in a blue uniform with binoculars standing in the crowd with troops and police. And if looks could kill me, we could have all been dead.” He says the hatred and intimidation was intense. Kellogg, being white, was an immediate target among many white people. He didn’t realize how dangerous the event in Alabama was until he and the others in the bus heard about the death of Viola Liuzzo. The married mother of five from Detroit was shot and killed by members of the Ku Klux Klan while shuttling activists to the Montgomery airport. “We found out about her death on the ride back,” Kellogg recalled. “Because it was a loss of life, and it shows the violence … we could have been exposed to that danger!” After returning to LU, Kellogg’s outlook on life took a dramatic turn. Kellogg noted King’s belief that a person should be willing to die for important causes. “The idea is that life is about something larger and more important than your own immediate gratification, and career success or personal achievements,” Kellogg said. “The civil rights movement … it made me, it made my life more significant because it was about something important.” The civil rights movement influenced Kellogg to change his career path and to become a black history lecturer. Until this day, he has no regrets and believes that his choices made him as a better individual. The bus ride to Alabama, he says, began with the actions of just one student. Robert Newton Robert Newton was the initiator, recruiter and leader of the Lincoln University movement to join Dr. Martin Luther King’s march in Selma. “In the 60s much of the civil rights activists came out of college,” said Newton during a recent phone interview. Many of the events that involved segregation compelled college students to fight for equality. “We had selected boycotts of merchants, when blacks were not allowed to try on clothes,” Newton said. “You could buy clothes at department stores, but no blacks could work at the department stores as sales people. If you bought clothes there you couldn’t try them on, you had to buy them first and take them home and try them on.” Newton said the students risked their lives to be a part of history and influence change. He not only recognized the historic event of his fellow Lincolnites, but also recognized other college students and historical black colleges and universities who played a vital role in history. “You had the S.N.C.C organization, in terms of voting rights and other things, including a lot of participation and working off the bureau,” Newton said. Other schools and places such as UNT, Greenville and Howard University and other historically black schools had groups that came out as leaders. Newton believes that much has changed from 50 years ago. “I think we’ve certainly come a long way from what I’ve seen from the standpoint of growing up outside of Birmingham, Alabama,” Newton said. He believes that college campuses today are more organized in their approach to social causes. “The campus appears to be some more integrated amongst students in terms of organizations and friendships.” Barbara Flint Dr. Barbara Flint grew up in the southern part of Arkansas and came to Lincoln University in 1961. She describes her experience at Lincoln as “being at Lincoln when the world was changing.“ She was an active member of Lincoln’s History Club, which focused on current events and issues and influenced her decision to join the Selma march. “The first idea was to raise some money and then we started talking about ‘why can’t we go?’ I very much wanted to be a living witness in history.” Reflecting on the march and journey to Montgomery, Flint describes it as being filled with tension. “We were very conscious of the fact that once we got on the road past Tennessee we didn’t know what was going to happen,” said Flint during a February 2015 phone interview. “Many of the students had not been beyond Missouri, so they didn’t have that sense of what happens in the South. Having lived there you knew the balance as well as what is likely to happen and what is not likely to happen. As my father use to say, ‘you have to know how to stay on that line of balance.’” Upon arriving in Alabama she remembers the feeling of excitement and relief from everyone on the bus. “We were tired and very happy to be there and we were trying to figure out where we were going to join and get into the march,” Flint said. “There were so many people coming in and then we were also trying to stay together; that was one of the things that really stuck out for me, not just for us but the people who were coming in. You didn’t want to lose sight of the people you came with.” Flint says she was keenly aware of her surroundings. For her, it was more than just marching forward. “I can still hear those helicopters now,” Flint recalled. “Every time the helicopters would come over the sound would make people jump and look up - I think that demonstrated the extent of the tenseness that was there at the time because the helicopters kept coming over every few minutes.” She said that the marchers sang “we are not afraid,” but that fear remained with every step. “Just having been there and being a witness and marching you realize that I’m one of those drops that’s going to make up this flood and with this flood things will move,” said Flint. As a student at Lincoln in 1965, Flint says the Selma experience undoubtedly changed her life. “You can’t expect to do exactly what you came to Lincoln to do,” Flint says. “That march - along with all the other marchers and the action that was taking place - directly changed the paths that I and many other people at Lincoln would take.” She says current students and new generations need to reflect on their personal role in society. “Decide what needs to be done and ask yourself ‘how can I best contribute to it?’” Flint said. She notes technology and social media can be used to reach audiences in ways unavailable to her generation in 1965. “So you don’t always have to wait for someone else to step out there and say ‘let’s march,’ you can express your vision and your views and you have the means to do so (so) others can follow you. Jaci Newsom Jaci Newsom came to Lincoln in 1965 from Atlanta. She came to Lincoln to major in sociology and being in Jefferson City was largely different from what she had grown up with. “To be able to come into a restaurant, sit down and be served a nice meal was eye-opening to me,” said Newsom during a recent interview. She eventually became accustomed to the relaxed attitude of Missouri and was shocked by the situation she encountered on an out-of-town trip. “I took a bus trip from Atlanta to Pensacola and I encountered the worse racism that I have ever seen. I was at bus stop, I went in to be served and they would not serve me. There was a policeman sitting there at the table and he told me that privately owned places could select not to serve you.” Newsom describes her experience of marching in Montgomery as being one with a purpose. “We felt as though we achieved something - we felt a sense of unity,” Newsom said. “We were very excited (because) we were going to hear from Martin Luther King. To actually be in the presence of him and the other civil rights workers there was just such enthusiasm and excitement yet there was also some apprehension of what we might encounter.” Many of the marchers showed their inspiration and determination while pressing forward towards the grounds of the Alabama Capitol building. Newsom recalled that the marchers were singing the lyrics “ain’t gonna let nobody turn me around” and “we shall overcome.” “ I started seeing people just like me,” Newsom said. “I don’t recall any of the scowling, the hitting, the things I would see on TV later. I just saw a sea of humanity marching towards the Capitol. I don’t remember what Martin Luther King said but it was always the same message: keep the faith; we’re going to get where we’re going and let us remember what our purpose is.” Newsom offers advice on what individuals can do to make their society a more productive and peaceful place. “We have come a long way and we have ways to change things that we did not have before,” Newsom said. “You need to work in positive ways to change.” Referencing the recent unrest in Ferguson, Mo., she believes that people become destructive as a way to show and vent anger. Her generation, she says, was raised to react in lawful ways – and believe in hope. “We have faith to do things in a way that was lawful and it makes me sad what people do when they feel without hope, and there is hope,” Newsom says. “Non-violence does work - we need to include everyone to make this world a better place.” Newsom graduated from Lincoln in 1969 and describes her experience at Lincoln as, “I grew up and did more growing at Lincoln than I think I did for the rest of my life.”

Valor de marca colectiva: aproximación desde el enfoque de la eficiencia

El objetivo del trabajo consiste en analizar la eficiencia de las empresas que integran una marca colectiva en una industria productora de bienes de experiencia. El supuesto básico es que la marca colectiva tiene un impacto positivo en la eficiencia de las empresas acogidas a la misma, el cual viene explicado porque la reputación colectiva fomenta una inversión eficiente en calidad. Sin embargo, la marca colectiva también puede tener un efecto opuesto sobre los incentivos de una empresa a una inversión en calidad ya que dicha marca puede crear un incentivo a “free ride”. Nuestra propuesta defiende que la interacción entre estos factores opuestos, reputación colectiva y “free ride”, viene moderada por las características de la marca colectiva y de la propia empresa. La metodología aplicada en el contraste de estas hipótesis se apoya en el Análisis Envolvente de Datos para estimar la eficiencia, así como en modelos econométricos para explicar la eficiencia empresarial mediante características de la marca colectiva y de la empresa. Los resultados obtenidos en el ámbito de las bodegas españolas evidencian que las marcas colectivas tienen un impacto positivo sobre la eficiencia, el cual viene moderado por el tamaño de la marca colectiva generando una relación curvilínea en forma de U invertida. Adicionalmente, el volumen de producción de la marca colectiva y el tamaño de las bodegas ejercen un efecto moderador en el impacto del tamaño de la marca colectiva sobre la eficiencia. En general, los resultados ponen de manifiesto la importancia de las marcas colectivas cuando se investigan industrias donde la calidad no es solamente señalizada por una marca típica individual.

Taking stock after the Warsaw COP. CEPS Commentary, 4 December 2013

Drawing on his direct participation in the latest round of climate talks in Warsaw, Andrei Marcu looks at the results of the 19th COP through the lens of three basic questions, with a view to understanding how much progress was made and where we stand two years ahead of Paris. Are the targets adequate and how do we reach environmentally adequate targets? Can one understand and compare what other Parties are promising to do to ensure that the level of effort is comparable and equitable, and that companies are not asked to do more than their competitors in other jurisdictions? Is there comparability and equity in the eyes of the beholder? Do we understand what tools each country uses (what is available, what one gets as support) to ensure that no one country (and its companies) gets an easier ride or competitive advantage in meeting the commitment/promises that countries make. The author asserts that these questions need to be answered if an agreement is to be reached in 2015. And if they are not, he warns of mistrust, fear of carbon leakage and the temptation to resort to protectionist measures to compensate for competitive disadvantage.

The Single Supervisory Mechanism: A Sound First Step in Europe’s Banking Union? Egmont European Affairs Paper, March 2013

The financial and economic crisis has hit Europe in its core. While the crisis may not have originated in the European Union, it has laid bare structural weaknesses in the EU’s policy framework. Both public finances and the banking sector have been heavily affected. For a long time, the EU failed to take into account sufficiently the perverse link that existed between the two. Negative evolutions in one field of the crisis often dragged along the other in its downward spiral. In June 2012, in the early hours of a yet another EU Summit, the leaders of the eurozone finally decided to address the link between the banking and sovereign debt crises. Faced with soaring public borrowing costs in Spain and Italy, they decided to allow for the direct European recapitalisation of banks when the Member State itself would no longer be in a position to do so. In exchange, supervision of the banking sector would be lifted to the European level by means of a Single Supervisory Mechanism. The Single Supervisory Mechanism, or SSM in the EU jargon, is a first step in the broader revision of policies towards banks in Europe. The eventual goal is the creation of a Banking Union, which is to carry out effective surveillance and – if needed – crisis management of the banking sector. The SSM is to rely on national supervisors and the ECB, with the ECB having final authority on the matter. The involvement of the latter made it clear that the SSM would be centred on the eurozone – while it is to remain open to other Member States willing to join. Due to the ongoing problems and the link between the creation of the SSM and the recapitalisation of banks, the SSM became one of the key legislative priorities of the EU. In December 2012, Member States reached an agreement on the design of the SSM. After discussions with the European Parliament (which were still ongoing at the time of writing), the process towards making the SSM operational can be initiated. The goal is to have the SSM fully up and running in the first half of 2014. The decisions that were taken in June 2012 are likely to have had a bigger impact than the eurozone’s Heads of State and Government could have realised at the time for two important reasons. On the one hand, creating the SSM necessitates a full Banking Union and therefore shared risk. On the other hand, the decisions improved the ECB’s perception of the willingness of governments to take far-reaching measures. This undoubtedly played a significant role in the creation of the Outright Monetary Transactions programme by the ECB, which has led to a substantial easing of the crisis in the short-term. 1 These short-term gains should now be matched with a stable long-term framework for bank supervision and crisis management. The agreement on the SSM should be the first step in the direction of this goal. This paper provides an analysis of the SSM and its role in the creation of a Banking Union. The paper starts with a reminder of why the EU decided to put in place the SSM (§1) and the state of play of the ongoing negotiations on the SSM (§2). Subsequently, the supervisory responsibilities of the SSM are detailed, including its scope and the division of labour between the national supervisors and the ECB (§3). The internal functioning of the SSM (§4) and its relation to the other supervisors are discussed afterwards (§5). As mentioned earlier, the SSM is part of a wider move towards a Banking Union. Therefore, this paper sheds light on the other building blocks of this ambitious project (§6). The transition towards the Banking Union is important and will prove to be a bumpy ride. Before formulating a number of conclusions, this Working Paper therefore provides an overview of the planned road ahead (§7).

Imperial legacy? The EU's Developmental Model and the Crisis of the European Periphery. CES Papers - Open Forum #19, 2013-2014

The high hopes for rapid convergence of Eastern and Southern EU member states are increasingly being disappointed. With the onset of the Eurocrisis convergence has given way to divergence in the southern members, and many Eastern members have made little headway in closing the development gap. The EU´s performance compares unfavourably with East Asian success cases as well as with Western Europe´s own rapid catch-up to the USA after 1945. Historical experience indicates that successful catch up requires that less-developed economies to some extent are allowed to free-ride on an open international economic order. However, the EU´s model is based on the principle of a level-playing field, which militates against such a form of economic integration. The EU´s developmental model thus contrasts with the various strategies that have enabled successful catch up of industrial latecomers. Instead the EU´s current approach is more and more reminiscent of the relations between the pre-1945 European empires and their dependent territories. One reason for this unfortunate historical continuity is that the EU appears to have become entangled in its own myths. In the EU´s own interpretation, European integration is a peace project designed to overcome the almost continuous warfare that characterised the Westphalian system. As the sovereign state is identified as the root cause of all evil, any project to curtail its room of manoeuvre must ultimately benefit the common good. Yet, the existence of a Westphalian system of nation states is a myth. Empires and not states were the dominant actors in the international system for at least the last three centuries. If anything, the dawn of the age of the sovereign state in Western Europe occurred after 1945 with the disintegration of the colonial empires and thus historically coincided with the birth of European integration.

Annotated record of the detailed examination of Mn deposits from RIDA cruise stations

The cores and dredges described at this site were taken on the RIDA cruise from 1 May until 25 May 1984 by the Muséum National d'Histoire Naturelle from the R/V Marion Dufresne. A total of 45 cores and dredges were recovered along with underwater camera runs. They are available at MNHN for sampling and study.
