On the Great Trimaran-Catamaran Debate
On the Great Trimaran-Catamaran Debate Lawrence J. Doctors, Member, School of MechanicnJ and Manufacturing Engineering, The University of New South Wales, Sydney, NSW 2052, Australia Abdmct In the cumwtt work, a aydewaatic investigation into a variety of monohulls and mul- tihulls is carried out with an emphasis on finding optimal forms. Vessels with up to six identical subhulls are taken into consideration and a large range of lengths is studied. hT- thermore, sidehuli trimaran configurations are included in the investigation. There are two main purposes to this investigation. Firstly, one is interested in mini- mizing the wave resistance, becawe this is closely related to the wave generation and is of critical importance to the operation of river ferries. Secondly, it is also important to min- imize the total resistance, in order to reduce fuei costs and to permit long-range trips for ocean-going vessels. The theoretical predictions show that increasing the length beyond that normally accepted is beneficial in reducing both the wave Resistance and often the total resistance. I. the goal is to minimize wave resistance and if the length is constrained, the calculations also demon- strate that trimarans are superior to catamarans, which are in turn superior to monohulls. On the other hand, if the goal is to minimize the total resistance, then all the muh!ihulis (~m catamarans to hezamarans) are inferior to monohulls, except possibly at low speeds which are not of interest in thw study. Similarly, sidehull trimarans are shown to be inferior to catamarans except perhaps if rather great lengths are permitted. -
The Emergence of the Mahajanapadas
The Emergence of the Mahajanapadas Sanjay Sharma Introduction In the post-Vedic period, the centre of activity shifted from the upper Ganga valley or madhyadesha to middle and lower Ganga valleys known in the contemporary Buddhist texts as majjhimadesha. Painted grey ware pottery gave way to a richer and shinier northern black polished ware which signified new trends in commercial activities and rising levels of prosperity. Imprtant features of the period between c. 600 and 321 BC include, inter-alia, rise of ‘heterodox belief systems’ resulting in an intellectual revolution, expansion of trade and commerce leading to the emergence of urban life mainly in the region of Ganga valley and evolution of vast territorial states called the mahajanapadas from the smaller ones of the later Vedic period which, as we have seen, were known as the janapadas. Increased surplus production resulted in the expansion of trading activities on one hand and an increase in the amount of taxes for the ruler on the other. The latter helped in the evolution of large territorial states and increased commercial activity facilitated the growth of cities and towns along with the evolution of money economy. The ruling and the priestly elites cornered most of the agricultural surplus produced by the vaishyas and the shudras (as labourers). The varna system became more consolidated and perpetual. It was in this background that the two great belief systems, Jainism and Buddhism, emerged. They posed serious challenge to the Brahmanical socio-religious philosophy. These belief systems had a primary aim to liberate the lower classes from the fetters of orthodox Brahmanism. -
Two Great Adventurers, Battuta and Polo, Affect the Medieval World
Two Great Adventurers, Battuta and Polo, Affect the Medieval World When you take a trip, how do you record what you did? Do you take pictures, and maybe post some of them on a social media site? Or you do send postcards or emails to your family and friends about your travels? Do you keep a journal to record events as they happen? Ibn Battuta and Marco Polo traveled in a time around the 13th and 14th centuries when recording events was not as easy as it is today. Upon their return to their homes, both Ibn Battuta and Marco Polo wrote about their adventures. Their stories were very influential in stimulating trade and travel in the regions they visited. Ibn Battuta’s desire to see the lands where his fellow Muslims lived led him across Asia, Africa, and Europe and the seas. His nearly thirty years of travel began when he was twenty-one when he set off for a pilgrimage to Mecca. After that, he traveled over 75,000 miles. Ibn Battuta traveled by joining trading caravans. Caravans were bands of travelers who journeyed together for security and mutual aid. He told of his adventures when he returned home to Morocco, and those who heard his stories thought they should be written down. The sultan of Morocco commissioned a young court secretary named Ibn Juzayy to listen to Ibn Battuta’s stories and record them. It took two years to write everything down, and when they were finished, the result was the Rihla, a story of travels centered on a pilgrimage. -
Spirited Seafarers WANDERLUST / Malay Archipelago

AirAsia Inflight Magazine The Bajau Laut Spirited Seafarers WANDERLUST / Malay Archipelago Nomads of WORDS & PHOTOGRAPHY: Claudio Sieber/ theclaudiosieberphotography.com Sulu Sea Living on the water, moving from island to island, and sometimes settling along the coastal areas of the Malay Archipelago (though concentrated in the area of the Sulu Sea), the seafaring Bajau Laut live a simple life in some of the most enchanting places on earth. The charming Bajau Laut wooden stilt huts can accommodate anywhere between a family of four or five to a small community encompassing about 30 roommates. These stilt houses, which usually take three weeks to erect, are equipped with only basic necessities. 1. Pictured here is Nalu, a Bajau Laut who migrated from the Philippines 26 years ago. A self- taught carpenter, he can easily design a fishing boat in about a week all by himself, without even an initial sketch to go by. The traditional craft of boat building is passed down from generation to generation. 2. A young Bajau Laut boy flies a home-made kite in the stilt village of Bangau-Bangau, Semporna, Sabah. The simple kite is constructed from a plastic bottle, plastic material, bamboo string and a rope. 3. A stunning vista enjoyed by the Bajau Laut who roam the seas. As a result of comprehensive conservation efforts by Sabah Parks authorities, the reefs at Tun Sakaran Marine Park remain pristine, allowing marine life to flourish.

5. from Janapadas to Empire
MODULE - 1 Ancient India 5 Notes FROM JANAPADAS TO EMPIRE In the last chapter we studied how later Vedic people started agriculture in the Ganga basin and settled down in permanent villages. In this chapter, we will discuss how increased agricultural activity and settled life led to the rise of sixteen Mahajanapadas (large territorial states) in north India in sixth century BC. We will also examine the factors, which enabled Magadh one of these states to defeat all others to rise to the status of an empire later under the Mauryas. The Mauryan period was one of great economic and cultural progress. However, the Mauryan Empire collapsed within fifty years of the death of Ashoka. We will analyse the factors responsible for this decline. This period (6th century BC) is also known for the rise of many new religions like Buddhism and Jainism. We will be looking at the factors responsible for the emer- gence of these religions and also inform you about their main doctrines. OBJECTIVES After studying this lesson, you will be able to explain the material and social factors (e.g. growth of agriculture and new social classes), which became the basis for the rise of Mahajanapada and the new religions in the sixth century BC; analyse the doctrine, patronage, spread and impact of Buddhism and Jainism; trace the growth of Indian polity from smaller states to empires and list the six- teen Mahajanapadas; examine the role of Ashoka in the consolidation of the empire through his policy of Dhamma; recognise the main features– administration, economy, society and art under the Mauryas and Identify the causes of the decline of the Mauryan empire. -

Performance Evaluation of the 19Th Century Clipper Ship Cutty Sark: a Comparative Study
Performance Evaluation of the 19th Century Clipper Ship Cutty Sark: A Comparative Study C. Tonry1, M. Patel1, C. Bailey1, W. Davies2, J. Harrap2, E. Kentley2, P. Mason2 1University of Greenwich, London, UK 2 Abstract The Cutty Sark, built in 1869 in Dumbarton, is the last intact composite tea clipper ship [1]. One of the last tea clippers built she took part in the tea races back from China. These races caught the public imagination of the day and were widely reported in newspapers [2]. They developed from a desire for 'fresh' tea and the first ship to return with the new season's tea could charge a higher price for the cargo. Clipper ships were built for speed rather than carrying capacity. The hull efficiency of the Cutty Sark and her contemporaries is currently unknown. However, with modern CFD techniques, virtual experiments can be performed to model the fluid flow past the hull and so based on the shear stress and the pressure over the surface of the hull to calculate the resistance. In order to compare the hull against other ships three other ships were selected. The Farquharson, an East Indiaman built in 1820 [3]; the Thermopylae, another composite clipper built in 1868 which famously raced the Cutty Sark in 1872 [1]; and finally the Erasmo a later Italian all-steel construction 4-masted barque built in 1903[4]. Fig. 1 shows images of these ships. As only one of these ships exists today, and she no longer sails, 3D geometries were constructed fromlines plans of the ships hulls. -
Stable-Ships of Tiruppudaimarudur and Tirukkurunkudi (South India)*
Indian Journal of History of Science, 44.4 (2009) 551-567 STABLE-SHIPS OF TIRUPPUDAIMARUDUR AND TIRUKKURUNKUDI (SOUTH INDIA)* JEAN DELOCHE** (Received 13 October 2008) In the district of Tirunelveli, South India, two works of art provide some significant information bearing on Indian nautical technology. The first one is found in the gopura of boat anchored in a harbour; the second one decorates the gateway of the Tirukkurunkudi temple with a relief which shows a ship disembarking horses and elephants. Though not strictly accurate, both the painting and carving are of an exceptional importance since they are the unique representations of the stable-ships which, for centuries, plied in the western part of the Indian Ocean, the first one coming from the Persian Gulf, the other, from the Red Sea. It is certain that these documents will be used by scholars to illustrate the fascinating history of horse trade from the Near East to India during the Medieval period. Key words: Boat, Persian Gulf, , Red Sea, Ship, Technology. INTRODUCTION The representations of ancient boats and ships in India are not numerous: some images on seals from the Harappan period, engravings on bas-reliefs and coins, from the 2nd century BC to the 7th century AD, Ajanta paintings (6th century) (Deloche 1996, pp. 199-224), carvings on memorial stones from the 11th-15th century (Deloche 1987, pp. 164-184), a few Rajput or Mughal miniatures (Verma 1978, pp. 109-11, pl. LXXI); finally, the Maratha drawings in the Prince * Revised version of two of my articles published in Bulletin de l’Ecole française d’Extrême- Orient, 72 (1983) 1-11 and 76 (1987), 170, 182-84. -
Hornblower's Ships
Names of Ships from the Hornblower Books. Introduction Hornblower’s biographer, C S Forester, wrote eleven books covering the most active and dramatic episodes of the life of his subject. In addition, he also wrote a Hornblower “Companion” and the so called three “lost” short stories. There were some years and activities in Hornblower’s life that were not written about before the biographer’s death and therefore not recorded. However, the books and stories that were published describe not only what Hornblower did and thought about his life and career but also mentioned in varying levels of detail the people and the ships that he encountered. Hornblower of course served on many ships but also fought with and against them, captured them, sank them or protected them besides just being aware of them. Of all the ships mentioned, a handful of them would have been highly significant for him. The Indefatigable was the ship on which Midshipman and then Acting Lieutenant Hornblower mostly learnt and developed his skills as a seaman and as a fighting man. This learning continued with his experiences on the Renown as a lieutenant. His first commands, apart from prizes taken, were on the Hotspur and the Atropos. Later as a full captain, he took the Lydia round the Horn to the Pacific coast of South America and his first and only captaincy of a ship of the line was on the Sutherland. He first flew his own flag on the Nonsuch and sailed to the Baltic on her. In later years his ships were smaller as befitted the nature of the tasks that fell to him. -
A Hundred Years of Tagore in Finland
Cracow Indological Studies vol. XVII (2015) 10.12797/CIS.17.2015.17.08 Klaus Karttunen [email protected] (University of Helsinki) A Hundred Years of Tagore in Finland Summary: The reception of Rabindranath Tagore in Finland, starting from newspa- per articles in 1913. Finnish translations of his works (19 volumes in 1913–2013, some in several editions) listed and commented upon. Tagore’s plays in theatre, radio and TV, music composed on Tagore’s poems. Tagore’s poem (Apaghat 1929) commenting upon the Finnish Winter War. KEYWORDS: Rabindranath Tagore, Bengali Literature, Indian English Literature, Fin nish Literature. In Finland as well as elsewhere in the West, the knowledge of Indian literature was restricted to a few Sanskrit classics until the second decade of the 20th century. The Nobel Prize in Literature given to Rabindranath Tagore (1861–1941) in 1913 changed this at once. To some extent, the importance of Tagore had been noted even before—the Swedish Nobel Committee did not get his name out of nowhere.1 Tagore belonged to a renowned Bengali family and some echoes of this family had even been heard in Finland. As early as the 1840s, 1 The first version of this paper was read at the International Tagore Conference in Halle (Saale), Germany, August 2–3, 2012. My sincere thanks are due to Hannele Pohjanmies, the translator of Tagore’s poetry, who has also traced many details about the history of the poet in Finland. With her kind permission, I have used this material, supplementing it from newspaper archives and from my own knowledge. -
