Full textAbstract:
Abstract Following the death of the incumbent Henry James Pye in 1813, the office of poet laureate came under scrutiny from press, court and government figures alike, and was eventually bestowed upon Robert Southey, having first been turned down by Walter Scott. This article examines the selection process and questions why, after a century in which the reputation of the office had fallen so far, it provoked such concern in 1813, and was suddenly thought an appropriate office for such pre-eminent ‘geniuses’ as Scott and Southey. Situating the selection process in the context of recent scholarship on national identity, cultural production and public opinion, it will be argued that the laureateship in 1813 can give us a unique and illuminating perspective on ideas of Britishness, patriotism and literature at the start of the nineteenth century, and of the place of court and public with regards to these ideas. In particular, the case of the laureateship demonstrates the variety, contingency and usability of notions of Britishness during the Napoleonic Wars: the ways that different agents invoked and thereby fashioned competing national identities in accordance with the needs of their discursive contexts. One possible constellation of Britishness, which came to the fore in the Liverpool ministry’s prosecution of the war effort and in the contest between the Edinburgh and Quarterly Reviews, validated ‘traditional’ forms of cultural production and patriotism in which court—and laureateship—played a crucial part.

Plasmodium ofPhysarum polycephalumis a single huge (visible by naked eye) cell with a myriad of nuclei. The plasmodium is a promising substrate for non-classical, nature-inspired computing devices. It is capable of approximation of the shortest path in a maze, computation of planar proximity graphs and plane tessellations, primitive memory and decision making. The unique properties of the plasmodium make it an ideal candidate for a role of amorphous biological robots with massive parallel information processing and distributed inputs and outputs. We show that when adhered to a lightweight object resting on a water surface the plasmodium can propel the object by oscillating its protoplasmic pseudopodia. In experimental laboratory conditions and computational experiments we study phenomenology of the plasmodium-floater system, and possible mechanisms of controlling motion of objects propelled by on-board plasmodium.

Ningbo–Zhoushan Port Main Corridor project is important in the development of Zhoushan City, but its impact on the hydrodynamic characteristics of the Zhoushan sea area is still unclear. Finite volume method is used in the present study to solve the shallow water equations and establish a plane two-dimensional tidal current numerical model. The measured tidal current data of the Yangtze River Estuary and Hangzhou Bay is utilized to verify the accuracy of the model in simulating the tidal current process. The results indicate the model can numerically reproduce the tidal current process in the Hangzhou Bay–Yangtze River Estuary–Zhoushan sea area (HYZ). In addition, the dynamic characteristics of tidal currents in the Zhoushan sea area with and without piers are compared. The results show that the construction of the project changes the water level near the bridge piers and causes the water obstruction and deficiency in the front and behind the piers, respectively. Tidal flow velocity increases on sides of the piers with while a low velocity area is formed before and after the piers. The project construction exerts a small impact on the tidal currents but a strong influence on the local area near the bridge piers.

A 14C age estimate of 13 470 ± 130 BP (ISGS-1378) from organic material at the base of transgressive lake deposits exposed in a southern Lake Michigan shore bluff near Riverside, Michigan, confirms that an intra-Glenwood low-water phase occurred in the Lake Michigan basin during the Mackinaw (Cary – Port Huron) Interstade. The altitude of organic material at Riverside suggests that the water plane was at or below modern lake level during the intra-Glenwood low-water phase. This observation indicates that drainage from the Lake Michigan basin was eastward, probably through the Straits of Mackinac into the Lake Huron basin. Such a drainage pattern implies that the correlative lake occupying the Lake Huron basin (Arkona low-water phase) must have had a level either congruent with or below that of the Lake Michigan basin. This lake system ultimately drained from the Lake Huron basin through a low eastern outlet (probably the Trent River lowland). The existence of low-level lakes at this time also indicates that the ice margin of the Lake Michigan lobe must have retreated at least as far north as the Straits of Mackinac region during the Mackinaw Interstade.

Full textAbstract:
Luke Terlaak Poot, “Scott’s Momentaneousness: Bad Timing in The Bride of Lammermoor” (pp. 283–310) This essay takes up the debate at the beginning of Walter Scott’s The Bride of Lammermoor (1819), noting that critics have generally treated one figure in this debate—Dick Tinto, the painter who advises our narrator to use less dialogue and more descriptive language—as a strawman. Critics have mostly overlooked the extent to which Tinto articulates the dynamics of “momentaneousness,” an aesthetic principle drawn from Scott’s contemporary, Henry Fuseli. Fuseli defined a momentaneous painting as one that represents a moment with a clear past and future. For Fuseli, paintings ought to select pregnant moments for representation, moments from which whole narrative sequences can be intuited. Implicit in this notion is the belief that some moments are particularly suited to representation because they are qualitatively different from others—more fully narrative, because more indicative of larger processes of change. Turning to Scott’s novel, I show how this assumption features prominently in The Bride of Lammermoor, where it repeatedly produces unforeseen, calamitous consequences. The moment’s disruptive potential culminates in an aptly novelistic take on momentaneousness: the cliffhanger. The cliffhanger draws the act of reading into a circuit of temporal interruption and delay, reproducing the bad timing endemic to the novel’s plot. When read as an instance of momentaneous representation, The Bride’s climactic cliffhanger can be said to incorporate the reader’s own interpretive activity into the bewildering experience of historical time that the novel depicts. This technique, I argue, helps to account for The Bride’s peculiar place in the Waverley canon—its pessimistic historical vision and fatalistic narrative logic.

Full textAbstract:
Many existing pile-supported marginal wharves within ports along the West Coast of the United States were designed in the late 1960s and early 1970s using the seismic design criteria available then, which were much less robust than the current criteria. As a result, structures designed using these criteria have often been severely damaged during the past earthquakes. This paper investigates the modal properties and vulnerability of such structures by using advanced structural and soil modeling procedures to perform two-dimensional nonlinear plane-strain seismic analyses using time histories of ground displacement and excess pore water pressures within the underlying soil embankment. Results show that the wharf structure experiences large permanent deformations and undergoes failure of the piles and pile-deck connections and pullout of batter piles in tension under large seismic events. Such failures were observed at the Port of Oakland during the 1989 Loma Prieta earthquake and also during other earthquakes throughout the world.

Full textAbstract:
This paper presents a finite element analysis of a case study of a combined vacuum and surcharge load through prefabricated vertical drains (PVD) at a storage yard at Port of Tianjin, China. The top 15 m of soil at this site was very soft to soft and needed to be improved using preloading surcharges of more than 140 kPa. To avoid any stability problems associated with a high surcharge embankment, 80 kPa vacuum pressure combined with fill surcharge was applied (40 and 58 kPa for sections I and II, respectively). A plane strain analysis was performed using equivalent permeability and transformed unit-cell geometry. The converted (equivalent) parameters were incorporated in the finite element code ABAQUS, using the modified Cam-Clay theory. The performance of a trial embankment at the site of the storage yard is predicted on the basis of a constant vacuum pressure applied on the soil surface and distributed along the length of the drain. The predictions of settlement, pore-water pressure, and lateral displacement were compared with the available field data, and an acceptable agreement was found based on this numerical approach. The combination of vacuum and surcharge load can effectively shorten the preloading period, reduce the height of the embankment, and counterbalance excessive lateral displacements.Key words: consolidation, finite element analysis, plane strain method, soil improvement, vertical drains.

Full textAbstract:
AbstractThe design of proper antenna element (AE) for microwave-based head imaging or brain stroke detection is a crucial challenge in the development process of microwave imaging (MWI) systems. The main purpose of this paper was to design, fabricate, and experimentally verify the compact and dimensions-reduced H-slot antenna suitable for the new generation of multichannel MWI system for brain stroke detection. The slot antenna type was chosen based on the numerical study of three AEs available in the literature, i.e. bow tie, slot, and waveguide-based. The study was focused on the sensitivity of the antennae (change of magnitude and phase of S21) due to dielectric parameters change or type and diameter of inclusion in a head phantom representing a hemorrhagic (HEM) or ischemic (ISCH) stroke phantom, respectively. Further, the analysis of antenna radiation to lossy medium/air and its immunity against plane wave exposure was carried out. The H-slot antenna was fabricated and experimentally verified (measurements of reflection as well as transmission coefficients) using a liquid head phantom with inserted HEM stroke phantom (both prepared as a mixture of propylene glycol, water, and salt). The phantoms were filled inside the designed two-port test system. Numerical models were validated by comparing calculated and measured S-parameters. The sensitivity of the H-slot antenna to the presence of the HEM stroke phenomenon within the phantom of the head was also demonstrated. The main advantage of the proposed H-slot antenna is its small dimensions, easy, inexpensive, and repeatable fabrication as well as mechanical stability.

Full textAbstract:
Abstract. On 5 December 2018, a magnitude Mw 7.5 earthquake occurred southeast of Maré, an island of the Loyalty Islands archipelago, New Caledonia. This earthquake is located at the junction between the plunging Loyalty Ridge and the southern part of the Vanuatu Arc, in a tectonically complex and very active area regularly subjected to strong seismic crises and earthquakes higher than magnitude 7 and up to 8. Widely felt in New Caledonia, it was immediately followed by a tsunami warning, confirmed shortly after by a first wave arrival at the Loyalty Islands tide gauges (Maré and Lifou), and then along the east coast of Grande Terre of New Caledonia and in several islands of the Vanuatu Archipelago. Two solutions of the seafloor initial deformation are considered for tsunami generation modeling, one using a non-uniform finite-source model from USGS and the other being a uniform slip model built from the Global Centroid Moment Tensor (GCMT) solution, with the geological knowledge of the region and empirical laws establishing relationships between the moment magnitude and the fault plane geometry. Both tsunami generation and propagation are simulated using the Semi-implicit Cross-scale Hydroscience Integrated System Model (SCHISM), an open-source modeling code solving the shallow-water equations on an unstructured grid allowing refinement in many critical areas. The results of numerical simulations are compared to tide gauge records, field observations and testimonials from 2018. Careful inspection of wave amplitude and wave energy maps for the two simulated scenarios shows clearly that the heterogeneous deformation model is inappropriate, while it raises the importance of the fault plane geometry and azimuth for tsunami amplitude and directivity. The arrival times, wave amplitude and polarities obtained with the uniform slip model are globally coherent, especially in far-field locations (Hienghène, Poindimié and Port Vila). Due to interactions between the tsunami waves and the numerous bathymetric structures like the Loyalty and Norfolk ridges in the neighborhood of the source, the tsunami propagating toward the south of Grande Terre and the Isle of Pines is captured by these structures acting like waveguides, allowing it to propagate to the north-northwest, especially in the Loyalty Islands and along the east coast of Grande Terre. A similar observation results from the propagation in the Vanuatu islands, from Aneityum to Efate.

Full textAbstract:
Abstract Air–water and air–water–oil flows were analyzed in a complex channel prototype of a plate and shell heat exchanger (PSHE) with the aid of a fast camera. Air–water flows were characterized before the PSHE inlet port by electrical capacitance tomography (ECT). The effects of inlet pipe flow pattern (bubbly, stratified, or slug) and flow direction (upward or downward) on PSHE air–water flows were investigated. The resultant phase distribution within the PSHE channel was determined by imaging analysis. Instantaneous velocity fields projected on the channel frontal plane were obtained with particle image velocimetry (PIV) for the dispersed phase of bubbly flows. Stratified pipe flow pattern results in PSHE channel segregated flow. The thermal analysis of segregated flow patterns occurring in the hot and cold sides of a PSHE reveals that the countercurrent configuration may present worse heat transfer performance than the parallel one. PSHE multiphase flows are characterized by breakup phenomenon: the mixture among phases is intensified even if stratification occurs at the inlet port. Oil–water–air downward flows are characterized by oil–water emulsion at the channel center and by water and air–water streams at the channel external part. Oil–water–air upward flows are characterized by air–water and oil–water emulsions at the channel center and by the water stream at the channel external part.

In this section of the book, readers will encounter key documents pertaining to the genesis and the development of the penal settlement. Port Blair gets its name. Captain Henry Man, the first superintendent of the settlement, hoists the Union Jack. Many convicts escape from the settlement; captured run-away convicts are hanged; most die in the hands of aborigines; survivors, however, record their encounter with aborigines. Friendly signs with aborigines are initiated, and they are put to capture run-away convicts. Convict labour is channelized to control the sea passage. Lord Mayo visits the settlement in 1872 and succumbs to Shere Ali’s knife. The subjects of the texts include, but are not limited to, controlling penal libido, provision for public women, the question of ‘unnatural crime’ and sodomy, rules pertaining to the physical fitness of transported convicts, controlling malaria, convict marriage, and important individual cases on the question of repatriation of prisoners after their term of imprisonment.

Full textAbstract:
In adopting a more overt emigration-immigration parallel, this chapter connects cultural texts focusing on the Mediterranean Sea, and in particular the Channel of Sicily for its bridging and dividing function between the European and the African continents. In the cultural melting pot of the Mediterranean basin, this chapter identifies less a place of fluid encounters and exchanges than one of tensions, struggled-for opportunities, and even mortal dangers. The blurring of emigrant and immigrant desires and failures in Vincenzo Marra’s 2001 film Tornando a casa (Sailing Home), the coexistence of painful legacies of emigration and slavery in Kym Ragusa’s 2006 memoir The Skin Between Us: A Memoir of Race, Beauty and Belonging, and the survival-driven urge to flee Northern Africa for the post-colonial subject in Feven Abreha Tekle’s 2005 as-told-to self-narrative Libera are all staged, either partially or fully, in a Mediterranean that functions as a pre-occupied space. Occupied by previous stories of demographic and cultural movements, this sea now hosts new concerns over economic stability, human rights protection, and racial tolerance, as well as new possibilities. Geographer Edward Soja’s concept of “Thirdspace,” developed off of Henri Lefebvre’s space trialectics, is adopted to recognize the transformative power of international waters over national identities.

One day at Ithaca I had screwed my courage to the sticking point, hopped on my Honda scooter, scooted over to the Ithaca airport, and joined the East Hill Flying Club, an organization that owned a Piper Cub and a Tri-Pacer, and I learned how to fly. I had taken a few lessons at the age of fourteen, but quit when we began to do stalls and my stomach had dropped faster than the plane. Now I found that although I was still scared, I could handle it, and I progressed quickly. Probably the single most terrifying, exhilarating moment in my life was my first solo. I hadn’t yet earned my private pilot’s license, but I was able to fly by myself and was allowed, even encouraged, to take short crosscountry trips. For this—and for me—Ithaca was ideally suited. The Tri-Pacer had a four-hour range at 120 knots cruising speed, and Ithaca was well within flying range of Washington, New England, New York—and Brookhaven. I took off and was soon approaching Long Island Sound, and having second thoughts. Whenever I flew out of sight of the Ithaca airport I not only continually looked around the skies to be sure there were no other planes anywhere near me, I also kept my eyes on the ground, picking out level places where I could put the plane down if the motor in front of me ever quit. Now, approaching the Sound, it looked vast and never-ending, with Long Island nothing but a dim, dark line on the horizon. If the engine quit over that water, if I went down … I turned around, was ashamed of myself, turned back again, turned around again, took a deep breath and headed out over that endless expanse of water. Ten minutes later I was approaching Long Island. I skimmed over Port Jefferson, found the little airport that served the lab, and set her down smoothly. A cab took me to Brookhaven, I said hello to everyone, found Joe Zähringer’s notebooks, and was amazed.

Abstract The injection of choked gaseous jets into the still air is investigated experimentally motivated by many industrial applications including flares and burners. The objective is to study the effect of injection angle on the jet mixing with ambient air. The experimental methods consist of particle image velocimetry (PIV) using pulsed Nd:YAG lasers of a choked gas jet, seeded with aluminum oxide particles, injected into still air, seeded with water fog. The computational methods consisted of 7.7 million cells simulation using Star CCM+. The test conditions include injection angles of 0°, 15°, and 30°. The results including mean and fluctuating velocities and the flow vorticity are presented. The flow field is not symmetric along the injection axis due to the asymmetric triggering of expansion fans at the jet exit due to the inclined injection plane. Moreover, the numerical simulation reveals the complex interaction mechanism of the expansion fans and shockwaves within the injection port.

Abstract Floating wind turbines are becoming an important part of renewable offshore power generation, offering an opportunity to deliver green energy. The floating nature of the substructures permits wind turbine placement in deep water locations, probably out of sight of land. This paper presents the tow out design method requirements for the installation of floating offshore wind turbines. Most existing floating offshore wind turbines substructures are barge, semi submersible, TLP and Spar types and their installation methods have been developed from those used on offshore oil and gas structures. Whilst the turbines are derived from those used on fixed bottom offshore wind turbines. The paper summarises the weather window limitations for the various substructure types and installations phases, including the transportation to and from the offshore site and during the connection of mooring lines and electrical cables. The choice of construction materials i.e. steel or concrete, influence the draft of the substructure at the fit-out quay and hence during the tow offshore. Semi submersible and barge types are of shallow draft and can be fitted out alongside a quay. Spar types typically require deep water for construction in sheltered inshore waters. The Tension Leg Platform (TLP) floating wind turbine has minimum water plane area and hence has low intact stability during ocean tow and thus TLPs may require modified crane vessels for offshore installation. The paper will present recent advances in the tow out requirements of floating offshore wind turbines. Data will be provided on intact stability, damage stability, tow forces and motions during tow from fit out port to the offshore location.
