Mobiles brazilian operators have not reached the goals

30 Aug

Two  proposed by the Anatel for at least 95% in this indicator. company that regulates the activity of cellular companies in Brazil, Tim reached 89.51% in the rate of instantaneous transmission (upload speed and download accurate at the time of Internet use by the user) already Vivo got 93.55%.

The goals were related to mobile broadband.Anatel

Vivo claimed: ” systemic problems limited the number of measurements [the Anatel], which reduced the statistical validity of the data collected and made two results got too close to the rates set by the regulator. ”

Tim already said in a statement that “as compared to the instantaneous transmission rate, the company achieved the target in all states assessed, except in São Paulo, but clarifies that it is investing constantly focusing on development and optimization of their network.”

And now I can pay only 90% of the amount charged by the service provider?

Die F. W. Lancaster

28 Aug

Is much discussion today about the semantics of the data, the Web tries to remake tLancasterhe way to organize your content via the Semantic Web, but these studies are present in Information Science and reference name is JW Lancaster.

His book ” Indexação e Resumos: teoria e prática” (Indexing and Abstracting in Theory and Practice, with Brazilian translation made by Briquet Lemos, now in 2nd. Edition) was the first American edition awarded in 1991 by the American Society for Information Science, as best book of the year in the area.

Frederic Wilfrid Lancaster was born in 1933 in England, studied at the Newcastle School of Librarianship from 1950 to 1954, following his career in the public library system of Newcastle. In 1959, he immigrated to the United States, where he worked in private firms and specialized libraries in the development and evaluation of information retrieval systems.

It was one of the first to work the evaluation of databases and do fundamental work in information retrieval, with the classic work called the Medical Literature Analysis and Retrieval System (MEDLARS), who performed at the end of the 1960s, to the National Library of Medicine U.S. (Jackson, 2005).

Went to the University of Illinois in 1970, where he was professor ma Graduate School of Library and Information Science from the University, where he continued advising on development of information retrieval in automated systems, having rendered service to the CIA.

In an article published in 1978, Toward paperless information systems, 1978, and in later works, the author argued for the inevitability of change of publications on paper to a paperless society, perhaps the first person to write about this.

He was a teacher and mentor of the first Brazilian Masters course in the area in the 1970s,

The decision was then Koh against both companies, since the public interest is greater than the rights of companies keep information secret, and the decision of the Court of Appeals was made ​​unanimously.

“We recognize the importance of protecting the public interest in litigation and facilitate the understanding of such procedures,” decided the body of the court, reaffirming: “this interest, however, does not extend to mere curiosity about confidential information between parties, where the information is not definitive decision on the merits. ”

Particles, the universe and digital signals

22 Aug

In the early twentieth century, the physicsMatériaEscura2 model that is something we might call today the rigid bodies and low-speed, low compared to the speed of light, which became for quantum physics an important reference because it was she who changed our vision of mass and matter, creating a physical micro-particles that revolutionized even the way of thinking and it is important to understand the ‘information’ outside man.

All we can tell, all the model we have today of the whole universe is connected to this physical and she is about to meet a single model: the micro-particles, including photons particles and electro-magnetic waves in a single model, called Standard Model of Physics, the discovery of the Higgs particles or Particle of God in recent experiment done in the particle accelerator at the borders of France to Swizerland it helps this model.

But we must understand that this model corresponds to only what we understand as matter, that this is most stable part of the universe, and physicists call baryonic matter, even though 22% of this it is a “dark matter” (baryonic and non-baryonic) , and there are still a matter totally unknown, but acting on gravitational attraction, which is called dark energy, which permeates the darkness of space.

This information model profoundly influenced the thought of Claude Shannon, a young student who worked on the influence of Norbert Wiener, father of cybernetics, and Vannevar Bush, both his professors at MIT, and which work very close in the late 30.

Later meet up with Alain Turing and then begin to develop this information model “quantized” who wrote in 1948 “The mathematical theory of communication, prefaces by Warren Weaver, and Wherefore sometimes called theory of Shannon-Weaver.

Shannon’s theory was essential to provide treatment “digital signals” analog for it some times is seen as a theory of digital signals and not information.


Big Data and Libraries

21 Aug

Technology Data Big Data is poised to revolutionize all aspects of human life and culture BigData3as people collect and analyze large volumes of data to predict behavior, problem solving, safety, and numerous other applications, is what ensures the site Christian Science Monitor.

The generation of large amounts of data is being driven by the increasing digitization of everyday activities and dependence on electronic devices of people who leave “fingerprints” concept that can be extended to trace “information”, since any object in any state conservation may contain “implicit” that is not yet in a suitable format.

The site CSMonitor cites a large data project which is a remarkable effort by the Library of Congress to archive millions of tweets per day, which can cost a lot of money for its historical value.

One example cited is the work of Richard Rothman, a professor at Johns Hopkins University in Baltimore, fundamental save lives.

The Centers for Disease Control and Prevention (CDC) in Atlanta predict flu outbreaks, and does so through the reports from hospitals.

But it took weeks, in 2009, appeared a study where researchers could predict outbreaks much faster through the analysis of millions of Web searches, queries made ​​as “My son is sick” and could learn a flu outbreak long before the CDC knew the reports of hospitals.

But the technologies of large volumes of data also has a boundary claim, in which technology is perceived potential distruir privacy, encourage inequality and promote government surveillance of citizens or others in the name of national security, how to reconcile these two trends ?
