Missing sets in rational parametrizations of surfaces of revolution  [PDF]
J. Rafael Sendra,David Sevilla,Carlos Villarino
Computer Science , 2014,
Abstract: Parametric representations do not cover, in general, the whole geometric object that they parametrize. This can be a problem in practical applications. In this paper we analyze the question for surfaces of revolution generated by real rational profile curves, and we describe a simple small superset of the real zone of the surface not covered by the parametrization. This superset consists, in the worst case, of the union of a circle and the mirror curve of the profile curve.
Information Revolution  [PDF]
Akshar Bharati,Vineet Chaitanya,Rajeev Sangal
Computer Science , 2003,
Abstract: The world is passing through a major revolution called the information revolution, in which information and knowledge is becoming available to people in unprecedented amounts wherever and whenever they need it. Those societies which fail to take advantage of the new technology will be left behind, just like in the industrial revolution. The information revolution is based on two major technologies: computers and communication. These technologies have to be delivered in a COST EFFECTIVE manner, and in LANGUAGES accessible to people. One way to deliver them in cost effective manner is to make suitable technology choices (discussed later), and to allow people to access through shared resources. This could be done throuch street corner shops (for computer usage, e-mail etc.), schools, community centers and local library centres.
The Darwinian revolution
Revista chilena de historia natural , 2010, DOI: 10.4067/S0716-078X2010000200004
Abstract: the scientific revolution probably began at 16th century with the heliocentric theory of the eminent astronomer nicolaus copernicus, but it was culminated with the masterful discoveries of galileo galilei and isaac newton at 17th century who revealed that planet movements around the sun and other similar phenomena can be explained by simple mechanical laws of physics and astronomy. however, the origin, complexity and configuration of living beings remained in the mystery until 19th century, with the publication of "on the origin of species". in this essay i discuss the importance of the darwinian scientific revolution, its beginnings, and the main objections of creationists to his evolutionary ideas. darwin demonstrated that the origin and complexity of living beings can be explained by natural processes, without the intervention of a supernatural being. however, the beginnings of the darwinian revolution were particularly difficult and 128 years after his death, the controversy between evolutionists and creationists still persists.
Fiction on Revolution
Moslem Zolfagharkhani
Studies in Literature and Language , 2012, DOI: 10.3968/2255
Abstract: The present study aims at showing Joseph Conrad’s Under Western Eyes as the author’s major deep concern about revolution and revolutionaries. Indeed the book is his memoire of both his past life and his mother country. The novel focuses on Razumov the central character and his unwanted involvement in political activities. Hence two worlds are depicted, one is the individual world of Razumov the student and the other is the communal world of the revolutionists. Under Western Eyes is a site for Conrad’s sentiments and inner responses where one comes across his obsessions about man and his society. Key words: Fiction; Joseph Conrad; Under Western Eyes; Revolution
The Sultan and the Revolution
John Monfries
Bijdragen tot de Taal-, Land- en Volkenkunde , 2008,
Abstract: One of the most famous events of the Indonesian Revolution is Sultan Hamengku Buwono’s successful defiance of the Dutch occupation of his city of Yogyakarta from December 1948 to June 1949. It may be timely to re-examine the episode, bearing in mind that Hamengku Buwono’s early career established the unusual constitutional arrangements in the Yogyakarta Special District which still remain in place today, nearly 60 years later.

The plane section of the surface of revolution  [PDF]
Obradovi? Ratko M.
Facta Universitatis Series : Architecture and Civil Engineering , 2005, DOI: 10.2298/fuace0502235o
Abstract: In this paper a procedure for determining a plane section of the surface of revolution was described. The surface of revolution is given by an axis of the revolution and a meridian which is coplanar with the axis. The axis of revolution is parallel to the z axis of the coordinate system. The intersecting plane is given by its three points; these are the points where the plane intersects axes x, y and z. For the determination of a plane section of the surface of revolution we can use horizontal planes which intersect the surface of revolution on parallel circles and each auxiliary plane intersects the intersecting plane on the horizontal line. Two points of the intersecting space curve are given as intersecting points between the horizontal line and the circle and new points of the intersecting curve have been determined by using several auxiliary planes.
A Cubic Surface of Revolution  [PDF]
Mark B. Villarino
Mathematics , 2013,
Abstract: We develop a direct and elementary (calculus-free) exposition of the famous cubic surface of revolution x^3+y^3+z^3-3xyz=1.12 pages. We have added a second elementary proof that the surface is of revolution.
Introduction — Ruptures in revolution
Irène Herrmann
La Révolution Fran?aise : Cahiers de l’Institut d’Histoire de la Révolution Fran?aise , 2011,
Abstract: On February 26 2011, during the so-called Jasmine Revolution, a Tunisian newspaper stated: “A revolution is, by definition, a rupture with the past”. This interpretation is not new and tellingly confirms what dictionaries and encyclopedias suggest. Revolutions are always defined as radical changes and thus indeed evoke the idea of a rupture with the past, of a break in continuity. This seemingly obvious interconnectedness might be the reason why the link between rupture and revolution has nev...
Challenges of the Knowledge Society , 2013,
Abstract: The paper attempts to highlight the main characteristics and the main flaws of the most important classification of theories of revolution, the generational approach. The first half aims to discuss and present the main tenets of the most important taxonomy of theories of revolution, as well as the similar attempts made by several scholars to build alternative classifications of theories of revolution. The second part of the paper attempts to show the limits of the aforementioned perspective and the importance of looking for alternative approaches to the study of revolutions. The paper considers that the generational perspective remains impermissibly flexible and elusive, ignoring the main paradigmatic debates within the field of study and maintaining a strong bias in favor of the clearest category, that of structural theories.
