Eduard Lill
Eduard Lill (1830–1900) was an Austrian engineer and army officer. Life Lill was born 20 October 1830 in Brüx ( Bohemia). From 1848 to 1849 he studied mathematics at the Czech Technical University in Prague and in 1850 he joined the military engineering corps of the Austrian Empire. From 1852 to 1856 he continued his education at the military engineering academy at Klosterbruck near Znaim. Later he was stationed in Esseg, Kronstadt and Spalato until he retired from his military career in 1868 with the rank of captain (Hauptmann) of the engineering corps. In the same year he became an engineer for the Austrian Northwestern Railway and oversaw the railroad construction at Trautenau (Trutnov). A severe accident however restricted him soon to office work. From 1872-1875 he worked as a secretary for the director of construction of the railway company. Later he became a technical consultant for company's headquarters and in 1885 the head of its statistics department. He retired in 18 ...

Horner's Method
In mathematics and computer science, Horner's method (or Horner's scheme) is an algorithm for polynomial evaluation. Although named after William George Horner, this method is much older, as it has been attributed to Joseph-Louis Lagrange by Horner himself, and can be traced back many hundreds of years to Chinese and Persian mathematicians. After the introduction of computers, this algorithm became fundamental for computing efficiently with polynomials. The algorithm is based on Horner's rule: :\begin a_0 &+ a_1x + a_2x^2 + a_3x^3 + \cdots + a_nx^n \\ &= a_0 + x \bigg(a_1 + x \Big(a_2 + x \big(a_3 + \cdots + x(a_ + x \, a_n) \cdots \big) \Big) \bigg). \end This allows the evaluation of a polynomial of degree with only n multiplications and n additions. This is optimal, since there are polynomials of degree that cannot be evaluated with fewer arithmetic operations. Alternatively, Horner's method also refers to a method for approximating the roots of polynomials, described by H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
19th-century Austrian Military Personnel
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1830 Births
Year 183 ( CLXXXIII) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Victorinus (or, less frequently, year 936 ''Ab urbe condita''). The denomination 183 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Hermann Knoflacher
Hermann Knoflacher (born 21 September 1940 in Villach) is an Austrian civil engineer. He was the head of the Institute for Transport Planning and Technology at the Vienna University of Technology. Life and teachings Knoflacher completed degrees in civil engineering, geodesy, and mathematics. Since 1975 he is a professor at the Vienna University of Technology. In 1985 he became head of the Institute for Transport Planning. His research focuses on spatial planning, urban planning, and transport planning. He is one of the key contributors to the sustainable transport movement (known as "''Sanfte Mobilität''" in German). Since 2004 he is the president of the Club of Vienna. He is also a member of the Club of Budapest and the global pedestrian representative of the United Nations. Knoflacher is well known for his criticism of excessive automobile usage and its effects on humans and the environment.

Route Capacity
Route capacity is the maximum number of vehicles, people, or amount of freight than can travel a given route in a given amount of time, usually an hour. It may be limited by the worst bottleneck (engineering), bottleneck in the system, such as a stretch of road with fewer lanes. Air traffic route capacity is affected by weather. For a Metro (rapid transit), metro or a light rail system, route capacity is generally the capacity of each vehicle, times the number of vehicles per train, times the number of trains per hour (tph). In this way, route capacity is highly dependent on headway. Beyond this mathematical theory, capacity may be influenced by other factors such as slow zones, single-tracked areas, and infrastructure limitations, e.g. to useful train lengths. Overview Any assessment of the effectiveness of a transport network includes a calculation of what capacity is used, how it is used, and whether it is used effectively. For instance, overloaded routes may need to be upgra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lill's Method
In mathematics, Lill's method is a visual method of finding the real roots of a univariate polynomial of any degree. It was developed by Austrian engineer Eduard Lill in 1867. A later paper by Lill dealt with the problem of complex roots. Lill's method involves drawing a path of straight line segments making right angles, with lengths equal to the coefficients of the polynomial. The roots of the polynomial can then be found as the slopes of other right-angle paths, also connecting the start to the terminus, but with vertices on the lines of the first path. Description of the method To employ the method a diagram is drawn starting at the origin. A line segment is drawn rightwards by the magnitude of the first coefficient (the coefficient of the highest-power term) (so that with a negative coefficient the segment will end left of the origin). From the end of the first segment another segment is drawn upwards by the magnitude of the second coefficient, then left by the magnitud ...
