Bandwidth is a Rate at which electronic signals can travel through a medium, such as a wire, cable, or channel or capacity of network to transmit data on network. There are different transmissions medium such as audio video and voice. Bandwidth need is different in the all because these all are different data format. In analog transmission (such as of voice signals over copper telephone lines) bandwidth is measured in cycles per second (or Hertz); for example, a telephone conversation requires about 4,000 Hertz (4 KHz) of bandwidth. In digital transmission (such as of data from one computer to another) bandwidth is measured in bits per second (BPS); for example, modern modems can send and receive data at 56,000 bps (56 Kbps) over ordinary telephone lines. For the same amount of data, digital transmission requires more bandwidth than the analog transmission, and different types of data require very different bandwidths. For example, full motion video normally requires about 10 million bits per second (10 Mbps) bandwidth which is sufficient to carry 1,200 simultaneous telephone conversations. A typical voice signal has a bandwidth of approximately three kilohertz (3 kHz); an analog television (TV) broadcast video signal has a bandwidth of six megahertz (6 MHz) -- some 2,000 times as wide as the voice signal. Three bandwidth techniques involves are as like Traffic Management/QoS, Caching and Compression so these are different bandwidth techniques used over network .we manage it with UDP , because UDP is a connectionless and changeable transport protocol. The two ports serve to identify the end points within the source and destination machines. User Datagram Protocol is used, in place of TCP, when a dependable transfer is not required. However, UDP is never used to send important data such as web-pages, database information, etc. Flowing media such as video, audio and others use UDP because it propositions speed. The reason UDP is faster than TCP is because there is no form of flow control. No error checking, error correction, or acknowledgment is done by UDP.UDP is only concerned with speed. So when, the data sent over the Internet is affected by crashes, and faults will be present

Understanding India, Globalisation and Health Care Systems

...Bisht et al. Globalization and Health 2012, 8:32 http://www.globalizationandhealth.com/content/8/1/32 REVIEW Open Access Understanding India, globalisation and health care systems: a mapping of research in the social sciences Ramila Bisht1*, Emma Pitchforth2 and Susan F Murray3 Abstract National and transnational health care systems are rapidly evolving with current processes of globalisation. What is the contribution of the social sciences to an understanding of this field? A structured scoping exercise was conducted to identify relevant literature using the lens of India – a ‘rising power’ with a rapidly expanding healthcare economy. A five step search and analysis method was employed in order to capture as wide a range of material as possible. Documents published in English that met criteria for a social science contribution were included for review. Via electronic bibliographic databases, websites and hand searches conducted in India, 113 relevant articles, books and reports were identified. These were classified according to topic area, publication date, disciplinary perspective, genre, and theoretical and methodological approaches. Topic areas were identified initially through an inductive approach, then rationalised into seven broad themes. Transnational consumption of health services; the transnational healthcare workforce; the production, consumption and trade in specific health-related commodities, and transnational diffusion of ideas and......

Data Mining

...A Statistical Perspective on Data Mining Ranjan Maitra∗ Abstract Technological advances have led to new and automated data collection methods. Datasets once at a premium are often plentiful nowadays and sometimes indeed massive. A new breed of challenges are thus presented – primary among them is the need for methodology to analyze such masses of data with a view to understanding complex phenomena and relationships. Such capability is provided by data mining which combines core statistical techniques with those from machine intelligence. This article reviews the current state of the discipline from a statistician’s perspective, illustrates issues with real-life examples, discusses the connections with statistics, the differences, the failings and the challenges ahead. 1 Introduction The information age has been matched by an explosion of data. This surfeit has been a result of modern, improved and, in many cases, automated methods for both data collection and storage. For instance, many stores tag their items with a product-specific bar code, which is scanned in when the corresponding item is bought. This automatically creates a gigantic repository of information on products and product combinations sold. Similar databases are also created by automated book-keeping, digital communication tools or by remote sensing satellites, and aided by the availability of affordable and effective storage mechanisms – magnetic tapes, data warehouses and so on. This has created a......

Defeating Daesh

... SOCI 401A Culture and Anthropology February 16, 2016 Tracey Poirier Source: The Institute for the Study of War (ISW) and the Critical Threats Project (CTP).), Jan, 2016. “If you know the enemy and know yourself you need not fear the results of a hundred battles“ –– Sun Tzu, Chinese philosopher and military strategist, around 500 BC. “Our terrorism against America is blessed terrorism.” –– Osama bin Laden (on video) “The acme of this religion is jihad.” — Osama bin Laden (Bergen, 2001, p. 41) Many have asked, “what can we do to defeat the Islamic State of Iraq and al-Sham (ISIS)? ” There have been a variety of suggestions from airstrikes, isolation , establishing a national unity government in Iraq to the feasibility of a counter-offensive using 'local' militia's and only as a last resort U.S. Boots on the ground. These are all worthy ideas; however, it is imperative to get a fundamental understanding of what has caused this problem because ISIS is growing and becoming stronger (even though current air strikes and counter-offensives have been successful). Before a decision can be made a rigorous analysis is necessary, a sociological analysis, so that the United States and the rest of the world can determine what must be done regarding ISIS and why. (Thesis): This paper will argue that the challenge of removing IS lies in our ability to understand and realize that the terror group’s appeal is not its alleged goal of a regression to the...

...Naturwissenschaften (2004) 91:255–276 DOI 10.1007/s00114-004-0515-y REVIEW Ulrich Kutschera · Karl J. Niklas The modern theory of biological evolution: an expanded synthesis Published online: 17 March 2004  Springer-Verlag 2004 Abstract In 1858, two naturalists, Charles Darwin and Alfred Russel Wallace, independently proposed natural selection as the basic mechanism responsible for the origin of new phenotypic variants and, ultimately, new species. A large body of evidence for this hypothesis was published in Darwin’s Origin of Species one year later, the appearance of which provoked other leading scientists like August Weismann to adopt and amplify Darwin’s perspective. Weismann’s neo-Darwinian theory of evolution was further elaborated, most notably in a series of books by Theodosius Dobzhansky, Ernst Mayr, Julian Huxley and others. In this article we first summarize the history of life on Earth and provide recent evidence demonstrating that Darwin’s dilemma (the apparent missing Precambrian record of life) has been resolved. Next, the historical development and structure of the “modern synthesis” is described within the context of the following topics: paleobiology and rates of evolution, mass extinctions and species selection, macroevolution and punctuated equilibrium, sexual reproduction and recombination, sexual selection and altruism, endosymbiosis and eukaryotic cell evolution, evolutionary developmental biology, phenotypic plasticity, epigenetic inheritance and...

The Logistic Map

...The (re-)discovery of the chaotic behaviour of the discrete version of this logistic model in the late previous century is reminded. We conclude by referring to some generalizations of the logistic model, which were used to describe growth and diffusion processes in the context of technological innovation, and for which the author studied the chaotic behaviour by means of a series of computer experiments, performed in the eighties of last century by means of the then emerging “micro-computer” technology. 1 P.-F. Verhulst and the Royal Military Academy in Brussels In the year 1844, at the age of 40, when Pierre-Fran¸ois Verhulst on November c 30 presented his contribution to the “M´moires de l’Acad´mie” of the young e e Belgian nation, a paper which was published the next year in “tome XVIII” with the title: “Recherches math´matiques sur la loi d’accroissement de la e population” (mathematical investigations of the law of population growth), he did certainly not know that his work would be the starting point for further research by Raymond Pearl and Lowell J. Reed [10, 11], by the famous A.-J. Lotka [8] and independently by Volterra [16] and later by V.A. Kostitzin [5], in the fields of mathematical biology, biometry, and demography.

Rock Climbers Perception of Responsible Tourism in Waterval Boven

...CHAPTER 1 INTRODUCTION 1.1 INTRODUCTION Tourism is, according to the Department of Environmental Affairs and Tourism (2002a), the world’s largest economical sector. In 2002, tourism in South African had a growth rate of 11.1 % in foreign arrivals from the previous year. That accounted for 6,4 million foreign tourists (South African Tourism, 2003). In 2003 it grew with another 1.2 % to 6,5 million tourists (South African Tourism, 2004), and in 2004, the number had increased to more than 6,8 million foreign tourists that visited South Africa (Geldenhuys, 2005:10). This shows that South Africa is becoming a popular travel destination among tourists. South Africa is a diverse country with many unique cultures and historical significances. South African Tourism have established that tourists experienced the hospitality and friendliness of the South African people as the most satisfactory of their visit in South Africa (Geldenhuys, 2005:10), and in a recent international survey done by American Express (Geldenhuys, 2005:10), South Africa was rated as the second-cheapest destination. Attractions such as Table Mountain, Robben Island, the Garden Route, Namaqualand, the Cradle of Human Kind, the Kruger National Park, the Drakensberg Mountains, and Soweto are just some of the South African examples (South African Tourism, 2005a). The towns and cities of South Africa such as Durban, Johannesburg, Port Elizabeth, and Cape Town also serve as attractions (South African Tourism,......
