A TAXICAB VERSION OF A TRIANGLE' S APOLLONIUS CIRCLE
One of the most famous problems of classical geometry is the Apollonius' problem asks construction of a circle which is tangent to three given objects. These objects are usually taken as points, lines, and circles. This well known problem was posed by Apollonius of Perga ( about 262 - 190 B.C.) who was a Greek mathematician known as the great geometer of ancient times after Euclid and Archimede...
متن کاملBus Rapid Transit Technologies: A Virtual Mirror for Eliminating Vehicle Blind Zones
The FTA has identified the concept of Bus Rapid Transit as a means to increase the efficiency of transit operations while maintaining transit's proven safety record. According to the FTA website www.fta.dot.gov, " BRT combines the quality of rail transit and the flexibility of buses. It can operate on exclusive transitways, HOV lanes, expressways, or ordinary streets. A BRT system combines inte...
متن کاملMeasurement of Mirror Birefringence at the Sub-Ppm Level: Proposed Application to a Test of QED
We present detailed considerations on the achievable sensitivity in the measurement of birefringence using a high finesse optical cavity, emphasizing techniques based on frequency metrology. Alternative approaches of laser locking and cavity measurement techniques are discussed and demonstrated. High-precision measurements of the cavity mirror birefringence have led to the interesting observati...
متن کاملAn analysis of Bordeaux meridian transit circle observations of planets and satellites (1997-2007)
Context. Meridian transit circle observations of the planets and their satellites are regularly performed for ephemerides improvement. Some have been made in Bordeaux observatory during the period 1997-2007. Aims. This paper presents these observations and makes an analysis of the data in order to determine the accuracy of the observations, their interest for dynamical purpose and a comparison ...
متن کاملCircle Line Optimization of Shuttle Bus in Central Business District without Transit Hub
The building density of Central Business District (CBD) is usually high. Land for a bus terminal is insufficient. In this situation, passengers in CBD have to walk far to take a bus, or take a long time to wait for a taxi. To solve this problem, this paper proposes an indirect approach: the design of a circle line of shuttle bus as a dynamic bus terminal in CBD. The shuttle bus can deliver peop...
