elements that enable otherwise passive data systems to search for patterns and relationships and discover knowledge in data streams.
The research holds solutions to the technical difficulties that resulted in the Air France flight 447 crash, which killed 228 people when it plunged into the Atlantic Ocean in 2009. According to Rensselaer Polytechnic Institute Carlos Varela, associate professor of computer science, 30 lines of computer code might have saved them.
AF447 went down after a pitot tube freeze, a scary malfunction that Varela knows well. When it froze on his flight from Albany Under Armour Shoes For Boys to Washington, readings became wonky. But in that situation, Varela went with his own logic rather than the plane instrument readings. Despite the urge to make the corrections the system suggested, he deducted that his airspeed indication was wrong and acted accordingly.
problem is there are too many things that can go wrong, so it hard to know exactly what went wrong when reading data, Varela said, but his autopilot system knows best.

a lot of current computer systems rely on data as truthful, Varela said, although that isn always the case.

Computer science graduate student Shigeru Imai presented the research and results at the International Conference Big Data Science and Engineering in December 2013.
creating a programming language, we make developing these kinds of systems much easier, Varela said. idea is to develop safer flight systems based on this notion of active data.
As a computer science minded pilot, Varela recognized that better active data systems could have prevented the crash of flight AF447, and in 2011 he decided to do something about it.
you can capture the patterns that arise when different correlated data streams are erroneous in a mathematical model, then you can correct for the data and avoid the unexpected behavior of the systems, Varela explained.
Varela research to developing active data was funded by the Air Force Office of Scientific Research under the Dynamic Data Driven Application Systems program, aimed to develop mathematical and programming Under Armour Curry White And Gold
The PILOTS programming language, though designed for this particular aviation study, can be utilized in other Under Armour Curry 2.5 Men
can be used for any data streaming application, Varela said.
The system includes an error function to alert pilots of something like a pitot tube causing faulty data. Because its monitored in real time, anything out of order would alert the pilot so they can correct the problem properly, not based on the false reading.
The research group took actual data from Air France flight black box and put it in their system.
Varela is also a single engine private plane pilot. He has been piloting since 1996.
Currently, the research group is looking at the specifics of Tuninter Flight 1153, which fell into the ocean in 2005.
Varela and his students took the black box information from that flight and created a solution for the future of aviation. The group created a solution called the Language for spatiO Temporal data Streaming applications, or PILOTS.
quite scary, Varela said. not an easy situation to be in. If pilots aren on their game, this can be a deadly error, as it was in the Air France flight.
He hopes to explore, with collaboration, medicinal usages. With more sensors attached to the human body, their system could potentially correlate data that may indicate when someone will have a heart attack or seizure. may be things that indicate something could go wrong ahead of time, he said.
In the longer term, the system could possibly monitor video surveillance systems in real time and be able to detect anomalies such as the Boston Marathon bombing beforehand, rather than reviewing the material afterward. Though the data is less clear, it is a research question, Varela said.
