Researchers achieve these cables in the detection of seismic movements


Fiber optic cables are the best earthquake detectors, according to the study by Philippe Jousset and Thomas Reinsch of the GFZ German Research Center for Geosciences published in Nature Communications.

In this study, the scientists sent pulses of laser light through an optical fiber, which was part of a 15-kilometer-long cable deployed in 1994, within the telecommunications network on the Reykjanes peninsula, southwest of Iceland.

This light signal was analyzed and compared with data sets from a dense network of seismographs, results that even surprised the researchers themselves. "Our measurements revealed structural characteristics in the subsoil with an unprecedented resolution and showed signals that equaled the data points every four meters," Philippe Jousset said in a statement.

Although the method is not new in other applications, the team is the first worldwide that carried out such measurements on the surface of the ground for seismological purposes and with such a long cable.

The advantages of the new method are enormous since there are innumerable fiber optic cables throughout the world in the dense telecommunications network.

Especially in large cities with high seismic risks, such as San Francisco, Mexico City, Tokyo or Istanbul, and many others

After twenty years of Salesforce, what Marc Benioff got right and wrong about the cloud

Image
As we enter the 20th year of  Salesforce,  there’s an interesting opportunity to reflect back on the change that  Marc Benioff   created with the software-as-a-service (SaaS) model for enterprise software with his launch of Salesforce.com. This model has been validated by the annual revenue stream of SaaS companies, which is fast approaching $100 billion by most estimates, and it will likely continue to transform many slower-moving industries for years to come. However, for the cornerstone market in IT — large enterprise-software deals — SaaS represents less than  25 percent of total revenue , according to most market estimates. This split is even evident in the most recent high profile “SaaS”  acquisition of GitHub by Microsoft,  with  over 50 percent of GitHub’s revenue coming from the sale of their on-prem offering,  GitHub Enterprise .   Data privacy and security is also becoming a major issue, with  Benioff himself even pu...

What Will the Future of Gaming Look Like?

New gaming innovation at CES this year offered some real overhauls for PC gamers. In any case, as the digital and physical world turn out to be perpetually interwoven, gamers might not be shackled to screens for any longer. We chose to examine what the eventual fate of gaming might look like. In some respects, this year’s Consumer Electronics Show was a quiet one for gaming. None of the console giants wanted to reveal anything new. Yet CES 2018 had plenty for gamers to drool over. New PC peripherals offer enhanced controls and stunning graphics. In addition, the expo revealed what the future of gaming might look like. Instead of being shackled to screens, players may soon have the opportunity to get physical. The question is, will they want to? Instant Upgrades In the present, gaming is about fast reactions and even faster fingers. Every millisecond counts when you’re trying to run through your Overwatch enemies or score the winner in Rocket League. For players who enjoy this tradition...

"Both my prime supporter and I experienced childhood in families were the majority of our salary was subject to the organizations our folks were running. Afterward, I joined a product organization working back office apparatuses for home change contractual workers," prime supporter and President Mahyar Raissi let me know. "There I saw two imperative things. To start with, the majority of our clients were utilizing their own telephone numbers for business and they totally detested that. They'd need to put their numbers on the web or give it out to outsiders. This implied getting consistent calls when they were investing energy with their families or when they ...
