Metamaterial antennas are a class of antennas which use metamaterials to enhance or increase performance of the antenna system. Applying metamaterials to increase performance of antennas has garnered much interest. Demonstrations have shown that metamaterials could enhance the radiated power of an antenna. Materials which can attain negative magnetic permeability could possibly allow for properties such as an electrically small antenna size, high directivity, and tunable operational frequency. Left-handed material, also known as negative index material, and DNG metamaterial, has applications in aspects of antenna systems and sub systems. Antenna subsystems that apply metamaterials are being researched. Either double-negative slabs are...

High Quality Content by WIKIPEDIA articles! Metcalfe's law states that the value of a telecommunications network is proportional to the square of the number of connected users of the system (n2). First formulated in this form by George Gilder in 1993, and attributed to Robert Metcalfe in regard to Ethernet, Metcalfe's law was originally presented, circa 1980, not in terms of users, but rather of "compatibly communicating devices" (for example, fax machines). Metcalfe's law characterizes many of the network effects of communication technologies and networks such as the Internet, social networking, and the World Wide Web. It is related to the fact that the number of unique connections in a network of a number of nodes (n) can be expressed...

High Quality Content by WIKIPEDIA articles! Meteorological instrumentation is the equipment used to sample the state of the atmosphere at a given time. Each science has its own unique sets of laboratory equipment. However, meteorology is a science which does not use much lab equipment but relies more on field-mode observation equipment. In science, an observation, or observable, is an abstract idea that can be measured and for which data can be taken. Rain was one of the first quantities to be measured historically. Two other accurately measured weather-related variables are wind and humidity. Many attempts had been made prior to the 15th century to construct adequate equipment to measure atmospheric variables.

This work is aimed at the study of different methods for uncertainty evaluation in measurement, both theoretical and applied. In the metrological field, the internationally accepted approach for uncertainty evaluation implies use of the GUM (Guide to the Expression of Uncertainty in Measurement). There are however situations in which it may not perform satisfactorily, e.g. when the measurement function is non-linear. The JCGM (Joint Committee for Guides in Metrology) has recently described in Supplement 1 to the GUM an alternative method for uncertainty evaluation, that is propagation of distributions using a Monte Carlo method. This method requires however an appropriate knowledge of statistical distribution of input quantities, a hard...

Service firms are confronted with rapid technological developments, fast changes in customer requirements, and hypercompetition, leading to exceedingly short product life cycles. That is, under rapidly changing and highly competitive circumstances, the timely design, development, and marketing of new services with creative and innovative features are essential for a company?s survival. With the development of information and communication technology (ICT) such as internet or mobile technology, the focus on New Service Creation(NSC) has been moving from offline to online services. Especially, the creation of technology-based services has been paid more and more attention to. For above mentioned issues, this book supposes a systemic...

High Quality Content by WIKIPEDIA articles! Metre gauge refers to narrow gauge railways and tramways with a track gauge of 1000 mm (3 ft 3 3/ 8 in). In some African, American and Asian countries it is the main gauge. In Europe it has been used for local railways in France, Germany, and Belgium, most of which were closed down in mid 20th century. Only in Switzerland and northern Spain do huge metre gauge networks remain in continuous use. Also, many European urban trams run on metre gauge. With the revival of urban rail transport, in some cities metre gauge light metros were established, while in other cities metre gauge was replaced by standard gauge.

The Metropolitan line is part of the London Underground. It is coloured in TfL's Corporate Magenta on the Tube map and in other branding. It was the first underground railway in the world, opening on 10 January 1863. The main line runs from Aldgate in the City of London to Amersham, with branch lines to Uxbridge, Watford and Chesham. For the initial section of the line the rails are in tunnel for much of the way; beyond Baker Street, at Finchley Road the line runs in the open. Out of the 34 stations served, only 9 are underground. It is the oldest line and initially covered the bulk of the Underground system. Today it is the ninth busiest line on the network.

Since 2008, more than half of the world population lives in cities. To cope with this rapid urbanization in a sustainable manner, transit systems all around the world are likely to grow. By looking at 33 metro networks in the world, this book identifies the geometric properties and effects of network designs. For this work, a new methodology was developed and is explained thoroughly. Each system is first characterized along three axes: State, Form and Structure. The complexity and robustness of metros is then studied from a Network Science perspective. Subsequently, the impact of network design on ridership is studied, and positive relations are observed. As a practical case study, all of these concepts are applied to the new transit...

Only Fenchurch Street was located within the City of London itself. London had also seen a large increase in road traffic congestion in this period. Данное издание не является оригинальным.

The Maschinengewehr 30, or MG30 was a German-designed machine gun that saw some service with various armed forces in the 1930s. It was also modified to become the standard German aircraft gun as the MG15 and MG17. It is most notable as the design pattern that led to the MG 34 and MG 42, and thus is one of the major ancestors of many of the weapons in service which would later find widespread use into the 21st century.

The MG 42 (shortened from German: Maschinengewehr 42, or "machine gun 42") is a 7.92mm universal machine gun that was developed in Nazi Germany and entered service with the Wehrmacht in 1942. It supplemented and in some instances, replaced the MG 34 general purpose machine gun in all branches of the German Armed Forces, though both weapons were manufactured and used until the end of the war. The MG 42 has a proven record of reliability, durability, simplicity, and ease of operation, but is most notable for being able to produce a stunning volume of suppressive fire. The MG 42 has one of the highest average rates of fire of any single-barreled man-portable machine gun, between 1,200 and 1,500 rpm, resulting in a distinctive muzzle report....
