Effects of gamma-Ray radiation on magnetic properties of NdFeB and SmCo permanent magnets for space applications

Several samples of NdFeB and SmCo permanent magnets have been irradiated with gamma rays up to different total irradiation doses until 1Mrad(Si). Magnetic properties of the samples have been measured at different temperatures before and after irradiation. The modifications of the magnetic parameters are presented. From these results it is highlighted which permanent magnets show more resistance to radiation and are more suitable to be included in devices for space applications or high radiation environments.

Impact of High-Speed Rail on Tourists' Decisions: Evidence from a Survey Conducted in Paris and in Madrid

The analysis of how tourists select their holiday destinations along with the factors that determine their choices is very important for promoting tourism. In particular, transportation is supposed to have influence on tourists? decissions. The objective of this paper is to investigate more especifically the role of High Speed Rail (HSR) in this choice. Two key tourist destinations in Europe, Paris and Madrid, have been chosen to understand the factors influencing this choice. On the basis of a survey conducted to tourists, we found out that some aspects such as the presence of architectural sites, the quality of promotion of the destination itself, and cultural and social events, have an impact on their choice. However the presence of the HSR system affects the choice of Paris and Madrid as a touristic destination in a different way. For Paris, TGV is considered a real transport mode alternative among tourists who use it quite often. On the other hand, Madrid is chosen by tourists irrespective of the presence of an efficient HSR network. Data collected from the two surveys have been used for a further quantitative analysis. Regression models have been specified and parameters have been calibrated to identify the factors influencing holidaymakers to revisit Paris and Madrid and visit other touristic spots accesible from HSR from these cities.

Histograms of oriented gradients for fast on-board vehicle verification

Histograms of Oriented Gradients (HoGs) provide excellent results in object detection and verification. However, their demanding processing requirements bound their applicability in some critical real-time scenarios, such as for video-based on-board vehicle detection systems. In this work, an efficient HOG configuration for pose-based on-board vehicle verification is proposed, which alleviates both the processing requirements and required feature vector length without reducing classification performance. The impact on classification of some critical configuration and processing parameters is in depth analyzed to propose a baseline efficient descriptor. Based on the analysis of its cells contribution to classification, new view-dependent cell-configuration patterns are proposed, resulting in reduced descriptors which provide an excellent balance between performance and computational requirements, rendering higher verification rates than other works in the literature.

The Double‐Edged Sword Of Interdict: Some More Warnings From History

In this paper I revisit the age-old question of the relationship between philosophy and theology by rejecting the claim that throughout the history of the Christian Church, whenever Christian thinkers have baptized philosophy, they have done so to the detriment of theology. Church history reveals just the opposite, i. e., that sometimes theologians have creatively and fruitfully used philosophical language, concepts, methods, and conclusions to understand and express the faith. In addition, church history records numerous attempts to limit philosophical enquiry for theological reasons that proved unsuccessful and counter-productive. Both types of interaction between philosophy and theology occurred at the University of Paris during the thirteenth century. Despite repeated efforts of some officials to place philosophy under interdict, that is, to ban the reading of particular philosophical works or the teaching of philosophical propositions from the university faculties, a series of university theologians applied Aristotelian tools of enquiry to questions about the Christian faith with positive and constructive results. If academic theology at Paris during the thirteenth century has anything to teach us, it is that interdict cuts both ways. It might protect some theological claims from philosophical contamination or compromise, but it can also insulate theological claims from much needed critical analysis. The thinkers and developments surveyed in this paper suggest that perhaps instead of placing deconstruction under interdict, today’s Christian thinkers should use some of the language, concepts, methods and conclusions of Derrida to further theological understanding.

Supporting the Revolution: America, Democracy, and the End of the Cold War in Poland, 1981-1989. ACES Working Paper (Report) No. 8, 2007

Early on the morning of December 13, 1981, General Wojciech Jaruzelski, the leader of the communist Polish United Workers' Party (PZPR), declared martial law, ending the so-called "Polish Crisis," which began with the creation of the Independent Free Trade Union "Solidamosc" in August 1980. Over the next eight years, the Communist government and the opposition struggled over power, culminating in 1989 with the creation of a Solidamosc-led government which ended fifty years of Communist rule in Poland and led the way to further democratic revolutions throughout Eastern Europe. The purpose of this dissertation is to utilize newly available and underutilized archival sources as well as oral history interviews, from both international and American perspectives, to fully chronicle American policy toward Poland from the declaration of martial law until the creation of the Solidarnosc government. Rather than explaining Polish-American relations in bilateral terms, the dissertation illuminates the complex web of influences that determined American policy in Washington and affected its implementation within Poland. This includes descriptions of internal tensions within the Reagan administration, differences between American decisions in Washington and implementation in Warsaw, lobbying from Polish-American groups, clashes between Capitol Hill and the White House, coordination with American labor organizations to support Solidarnosc, disagreements with West European allies in NATO and international financial organizations, cooperation with the Vatican and the Polish Catholic Church, synchronization with American humanitarian organizations working in Poland, limitations caused by the realities of Soviet power in Eastern Europe, and complications caused by domestic Polish concerns. By taking a broad view of American policy and highlighting internal Polish decisions, with both the Communist government and the democratic opposition, the dissertation provides concrete examples of America's role in Poland's transformation, arguing, however, that this role was very limited. These conclusions are relevant to arguments about the end of the Cold War, the nature of American power, as well as current discussions about possibilities to promote democracy within hostile regimes.

Annotated record of the detailed examination of Mn deposits from the TRANSINDIK R/V Valdivia (VA 07) cruise stations

The studied material was taken from Central Indian Ocean central, during the "TRANSINDIK" campaign of the R/V Valdivia. The campaign was conducted from 14 December 1973 until 23 January 1974, between Beira (Mozambique) and Singapore via Port Louis (Mauritius). The samples were taken on 14 stations aligned on a profile trending West, following approximately the 15th parallel (south). This profile cuts through the Mascarene plateau Basin. The preliminary study presented in this report was carried out as part of a study into the genesis and diagenesis the ocean deposits of the central and southern areas of the Indian Ocean (Laboratoire de GÈologie du MusÈum d'Histoire Naturelle - R.C.P. 212) and under the CNEXO No. 74/1017 contract. The data collected supplements the results of the OSIRIS campaign (R/V Marion Dufresne - TAAF) concerning relations existing between morphostructure and sedimentation and, more particularly, the nature and age of metalliferous deposits associated with Mn concretions.
