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. -

Stevenson Memorial Tournament 2018 Edited by Jordan Brownstein, Ewan MacAulay, Kai Smith, and Anderson Wang Written by Olivia Lamberti, Young Fenimore Lee, Govind Prabhakar, JinAh Kim, Deepak Moparthi, Arjun Nageswaran, Ashwin Ramaswami, Charles Hang, Jacob O’Rourke, Ali Saeed, Melanie Wang, and Shamsheer Rana With many thanks to Brad Fischer, Ophir Lifshitz, Eric Mukherjee, and various playtesters Packet 2 Tossups: 1. An algorithm devised by this person uses Need, Allocated, and Available arrays to keep the system in a safe state when allocating resources. This scientist, Hoare, and Dahl authored the book Structured Programming, which promotes a paradigm that this man also discussed in a handwritten manuscript that popularized the phrase “considered harmful.” Like Prim’s algorithm, an algorithm by this person can achieve the optimal runtime of big-O of E plus V-log-V using a (*) Fibonacci heap. This man expanded on Dekker’s algorithm to propose a solution to the mutual exclusion problem using semaphores. The A-star algorithm uses heuristics to improve on an algorithm named for this person, which can fail with negative-weight edges. For 10 points, what computer scientist’s namesake algorithm is used to find the shortest path in a graph? ANSWER: Edsger Wybe Dijkstra [“DIKE-struh”] <DM Computer Science> 2. A design from this city consists of a window with a main panel and two narrow double-hung windows on both sides. The DeWitt-Chestnut Building in this city introduced the framed tube structure created by an architect best known for working in this city. Though not in Connecticut, a pair of apartment buildings in this city have façades with grids of steel and glass curtain walls and are called the “Glass House” buildings. -

You Are Not Welcome Among Us: Pirates and the State
International Journal of Communication 9(2015), 890–908 1932–8036/20150005 You Are Not Welcome Among Us: Pirates and the State JESSICA L. BEYER University of Washington, USA FENWICK MCKELVEY1 Concordia University, Canada In a historical review focused on digital piracy, we explore the relationship between hacker politics and the state. We distinguish between two core aspects of piracy—the challenge to property rights and the challenge to state power—and argue that digital piracy should be considered more broadly as a challenge to the authority of the state. We trace generations of peer-to-peer networking, showing that digital piracy is a key component in the development of a political platform that advocates for a set of ideals grounded in collaborative culture, nonhierarchical organization, and a reliance on the network. We assert that this politics expresses itself in a philosophy that was formed together with the development of the state-evading forms of communication that perpetuate unmanageable networks. Keywords: pirates, information politics, intellectual property, state networks Introduction Digital piracy is most frequently framed as a challenge to property rights or as theft. This framing is not incorrect, but it overemphasizes intellectual property regimes and, in doing so, underemphasizes the broader political challenge posed by digital pirates. In fact, digital pirates and broader “hacker culture” are part of a political challenge to the state, as well as a challenge to property rights regimes. This challenge is articulated in terms of contributory culture, in contrast to the commodification and enclosures of capitalist culture; as nonhierarchical, in contrast to the strict hierarchies of the modern state; and as faith in the potential of a seemingly uncontrollable communication technology that makes all of this possible, in contrast to a fear of the potential chaos that unsurveilled spaces can bring. -

Digest #: Title
#9052 TTHHEE LLIIVVIINNGG SSAANNDDSS AMBROSE VIDEO PUBLISHING 2000 Grade Levels: 9-13+ 52 minutes DESCRIPTION Focuses on animal life in four extremely inhospitable deserts: the Namib's adaptive elephant, a dromedary roundup in Australia's outback, fish in thermal lakes in Mexico's Chihuahua desert, and the Sahara's Ennedi crocodiles. Survival is an eternal challenge to any life in these places. ACADEMIC STANDARDS Subject Area: Science: Life Sciences • Standard: Understands relationships among organisms and their physical environment Benchmark: Knows how the interrelationships and interdependencies among organisms generate stable ecosystems that fluctuate around a state of rough equilibrium for hundreds or thousands of years (e.g., growth of a population is held in check by environmental factors such as depletion of food or nesting sites, increased loss due to larger numbers of predators or parasites) • Standard: Understands biological evolution and the diversity of life Benchmark: Understands the concept of natural selection (e.g., when an environment changes, some inherited characteristics become more or less advantageous or neutral, and chance alone can result in characteristics having no survival or reproductive value; this process results in organisms that are well suited for survival in particular environments) INSTRUCTIONAL GOALS 1. To list physical features and capabilities of the desert elephant, gemsbok, warthog, ostrich, dromedary, pupfish, and crocodile. 2. To research how these animals survive in their environment. BACKGROUND INFORMATION Evolutionary Adaptations Desert Elephant of the Namib Desert (Namibia): • “Snowshoe feet” provide a soft wide track on sand. • It survives days without water while the elephants of the savanna of East Africa drink 40 to 50 gallons a day. -

A Biographical Study of Bishop Ralph Edward Dodge 1907 – 2008
ABSTRACT Toward a New Church in a New Africa: A Biographical Study of Bishop Ralph Edward Dodge 1907 – 2008 This biography of a Methodist Bishop, Ralph Edward Dodge is an extensive look into how, as a missionary, mission board executive, and bishop, Dodge applied principles of indigenization he embraced as a young man preparing for missionary work to the complexities of ministry in Southern Africa when empires were withdrawing and new nations were forming. Written by an African, the dissertation examines Dodge’s impact upon the several countries in which he was involved as a churchman ‒ countries that would soon move from imperial subjugation to independence. Ralph Edward Dodge (1907–2008) was an American missionary and Bishop of the Methodist Church and United Methodist Church. He was born in Iowa and went to Africa in 1936 at age 29. He began his missionary career in the Portuguese colony of Angola. Except for four years during World War II, he would serve there until 1950. During the war, he continued his postgraduate work, obtaining two more degrees, including a PhD. Afterwards, Dodge and his family returned to Africa. In 1950, he was asked to serve as Executive Secretary for Africa and Europe at the Methodist Church’s Board of Missions in New York. Six years later, the Reverend Doctor Dodge would return to Africa as Bishop Dodge, the first Methodist Bishop elected by the Africa Central Conference, and the only American. His Episcopal Area included the colonial territories of Angola, Mozambique, and Southern Rhodesia (now Zimbabwe). When his twelve-year term was ended, he was elected “Bishop for Life.” Bishop Dodge remained in Africa until his “retirement” in 1968. -
