This article recommends a virtually unknown manuscript on the early Portuguese presence in India to wider scholarly attention. Dubbed here the Wye manuscript, this text purports to be an English translation of a sixteenth-century Malayalam history that was produced at the court of the ruler of Calicut. The South Indian kingdom of Calicut was central to Portugal’s project of monopolizing the region’s all-important pepper trade; the Wye manuscript therefore holds the promise of adding an Indian perspective to a history that has been written largely on the basis of European sources. This article examines the external and internal evidence for the author’s claim of having translated the text from an original palm-leaf manuscript held by members of Calicut’s royal family. An analysis of its content shows significant overlap with an Arabic history of the sixteenth century; a comparison of their similarities and differences suggests a number of insights into the processes of composition and revision of both the Malayalam and Arabic texts. Last, and most important, the Wye manuscript is transcribed in full in the hope of stimulating further discussion and study.

Abstract This is the second of a two-part special issue on piracy in Asian waters. Part 1 (vol. 16, no. 6) explored the social and economic dynamics of pan-Asian piracy, and here in Part 2, contributors delve into the political dimensions of piracy by focusing on its interrelationship with notions of sovereignty, the changing nature of states in early modern Asia, and the rise of global seaborne empires. The four articles here challenge the conventional wisdom that Asian waters were great voids in indigenous political imagination and that Asian polities never regulated maritime space before the arrival of the West. Piracy played a significant role in the intense economic rivalries and competing political claims over sovereignty, not just between Western imperial powers but also among indigenous polities. Maritime space, therefore, was actively contested by both European powers and by various Asian states. In this contestation the early modern Asian pirate served as both instrument and contender of nascent projects of empire-building and sovereignty.

Abstract Rulers on the Indian Ocean littoral are generally portrayed as having been uninterested in the pursuit of sea power until the coming of the Europeans. This article examines a series of case studies from this earlier period to argue that maritime violence had long been a part of expansionist political projects centered on the control of trade routes and coastal waters. In their sum, they show the Indian Ocean to have been an arena of active political competition and legal contestation, which were waged through private and semi-private agents commonly denoted as pirates.

Abstract Seafaring, and especially the use of seaborne violence, in the early modern period is strongly associated with European naval activity. In this issue and the next, this perspective is challenged through a sustained interrogation of indigenous piracy in Asian waters. A series of studies highlight the persistence, sophistication, and breathtaking scale of Asian piracy. They show how piracy was deeply ingrained in the social worlds, commercial exchanges, and political contestations across the Asian littoral. Based on these insights, it is argued that the study of piracy reveals the significance of an often-overlooked dimension of Asian maritime enterprise in the early modern period.

Of all the oriental spices, black pepper was the most important until the eighteenth century. The historiography of the pepper trade is characterized by a strong focus on Europe in terms of both its economic significance in the ancient and medieval periods and the struggle for its control in the early modern period. This article, by contrast, seeks to situate the pepper trade firmly in its Asian contexts. It examines the Indian Ocean pepper trade from three perspectives. First, it places the trade in its supply-side context by focusing on the Malabar coast as the primary source of pepper. Second, it examines the relative importance of the different branches of Malabar's pepper trade and highlights the central role played by Muslim mercantile networks. Third, it considers the reconfiguration of these pepper networks in the sixteenth century in the face of aggressive competition from the Portuguese. In their sum, these arguments advocate the need for rethought balances of trade and a reweighted scholarly focus on the pepper trade in its global dimensions.

This essay won the 2007 History Compass Graduate Essay Prize, World Section. This article surveys the historiography of the Indian Ocean to examine the problems and opportunities of using maritime spaces as frameworks for world history studies. It first considers the problem of demarcating maritime space according to different material and mental definitions. Its second part assesses different periodizations that reflect the main themes of scholarly engagement with the Indian Ocean. The final section looks at the emerging field of network studies as a new approach to the study of interconnections across the Indian Ocean world.

We present in this Keck AO paper the first global high angular resolution observations of Io in three broadband near-infrared filters: Kc (2.3 mu m), Lp (3.8 mu m), and Ms (4.7 mu m). The Keck AO observations are composed of 13 data sets taken during short time intervals spanning 10 nights in December, 2001. The MISTRAL deconvolution process, which is specifically aimed for planetary images, was applied to each image. The spatial resolution achieved with those ground-based observations is 150, 240, and 300 km in the Kc, Lp, and Ms band, respectively, making them similar in quality to most of the distant observations of the Galileo/NIMS instrument. Eleven images per filter were selected and stitched together after being deprojected to build a cylindrical map of the entire surface of the satellite. In Kc-band, surface albedc, features, such as paterae (R > 60 km) are easily identifiable. The Babbar region is characterized by extremely low albedo at 2.2 mu m, and shows an absorption band at 0.9 mu m in Galileo/SSI data. These suggest that this region is covered by dark silicate deposits, possibly made of orthopyroxene. In the Lp-Ms (3-5 mu m) bands, the thermal emission from active centers is easily identified. We detected 26 hot spots in both broadband filters over the entire surface of the minor planet; two have never been seen active before, nine more are seen in the Ms band. We focused our study on the hot spots detected in both broadband filters. Using the measurements of their brightness, we derived the temperature and area covered by 100 brightness measurements. Loki displayed a relatively quiescent activity. Dazhbog, a new eruption detected by Galileo/NIMS in August 2001, is a major feature in our survey. We also point out the fading of Tvashtar volcanic activity after more than two years of energetic activity, and the presence of a hot, but small, active center at the location of Surt, possibly a remnant of its exceptional eruption detected in February 2001. Two new active centers, labeled F and V on our data, are detected. Using the best temperature and the surface area derived from the L and M band intensities, we calculated the thermal output of each active center. The most energetic hot spots are Loki and Dazhbog, representing respectively 36 and 19% of the total output calculated from a temperature fit of all hot spots (20.6 x 10(12) W). Based on the temperature derived from hot spots (similar to 400 K), our measurement can unambiguously identify the contribution to the heat flux from the silicate portion of the surface. Because the entire surface was observed, no extrapolation was required to calculate that flux. It is also important to note that we measured the brightness of the individual hot spots when they were located close to the Central Meridian. This minimizes the line-of-sight effect which does not follow strictly a classical cosine law. Finally, we argue that despite the widespread volcanic activity detected, Io was relatively quiescent in December 2001, with a minimum mean total output of 0.4-1.2 W m(-2). This output is at least a factor of two lower than those inferred from observations made at longer wavelengths and at different epochs. (c) 2005 Elsevier Inc. All rights reserved.

Io, the innermost Galilean satellite of Jupiter, is a fascinating world. Data taken by Voyager and Galileo instruments have established that it is by far the most volcanic body in the Solar System and suggest that the nature of this volcanism could radically differ from volcanism on Earth. We report on near-IR observations taken in February 2001 from the Earth-based 10-m W. M. Keck II telescope using its adaptive optics system. After application of an appropriate deconvolution technique (MISTRAL), the resolution, ∼100 km on Io's disk, compares well with the best Galileo/NIMS resolution for global imaging and allows us for the first time to investigate the very nature of individual eruptions. On 19 February, we detected two volcanoes, Amirani and Tvashtar, with temperatures differing from the Galileo observations. On 20 February, we noticed a slight brightening near the Surt volcano. Two days later it had turned into an extremely bright volcanic outburst. The hot spot temperatures (>1400 K) are consistent with a basaltic eruption and, being lower limits, do not exclude an ultramafic eruption. These outburst data have been fitted with a silicate-cooling model, which indicates that this is a highly vigorous eruption with a highly dynamic emplacement mechanism, akin to fire-fountaining. Its integrated thermal output was close to the total estimated output of Io, making this the largest ionian thermal outburst yet witnessed.

The ten small inner moons of Uranus, discovered in 1986, have so far only been studied from space (Voyager 2, HST). The orbital elements derived from the observations indicate very weakly eccentric orbits for all of them but one (Ophelia). We present here the first ground-based astrometric observations of Puck, performed using an Adaptive Optics system. The long observing sequences permitted by ground-based facilities at ESO-La Silla, Chile (64.S-0289) revealed an eccentricity 100 times larger than previously believed. Such a disagreement with the actual theory may arise from the reduction itself based on the bright moons of Uranus, considered until now as precise astrometric references. To cite this article: P.

The physical character of local oscillators on a nm scale will be outlined. Next-neighbor coupling leads to percolation areas of about 100 nm as result of Monte Carlo simulations. The percolation provides an intrinsic synchronization mechanism leading to macroscopic oscillations.

International audience; After having used an analytical expression in the form of a power series expansion to calculate the interelectrode electrostatic field in the general case of a toroidal electrostatic analyzer, we derive approximate analytical expressions for the most interesting response functions (geometrical factor, angular aperture, energy resolution, etc.). Results of a study of the dependence of these quantities with respect to the geometrical parameters of the analyzers are given in the form of grids of curves. By using such grids one is able to determine the optimal parameters to obtain any particular solution. Examples of such a choise are given in the case of measurements of low energy particles in space (10 eV to 50 keV).

We study three models of electrostatic mirror analyzers and show that these kinds of instruments are inadequate to analyze energetic particles because they require too high retarding voltages compared to the mean energy of the particles analyzed.

We describe a rocket‐borne instrument for measurement of the low energy electron and proton distribution function in the magnetosphere. It consists of an optimized programmable electrostatic toroidal analyzer as an energy selector, coupled with an electron multiplier as a particle detector, and of the associated electronics. Much attention has been paid to the experimental calibration of the instrument which gives us some understanding of the real behavior of the detector and the way it influences the analyzer properties.
