A project funded by the Engineering and Physical Sciences Research Council and led by University of Nottingham researchers is developing a new computerized approach to scheduling airport operations that is designed to reduce delays, speed up baggage handling, and decrease pollution. The project aims to computerize and coordinate the scheduling of take-offs, landings, gate assignments, and baggage handling. The end result will be a search engine capable of analyzing the billions of possible scheduling combinations to provide the controllers with the most efficient courses of action. Currently, these four areas are organized manually by staff members who make decisions based on observations, reports, and experience. The scheduling improvements will make flying easier for passengers and reduce pollution by minimizing the time planes spend on the ground with their engines running. The project will develop computational models for each of the four areas of operations and determine how to run those models in conjunction with each other. One of the critical issues is how long an airplane needs for preparation on the ground before it can take off. Preparation includes enough time for the safety briefing and warming the engines. Sending a plane to the runway before either of these steps has taken place will cause delays on the runway that could affect other flights.

University of Edinburgh researchers used low-energy lasers to make salt crystals in gel, which could make it possible to store a terabyte of data in a space the size of a sugar cube within the next 10 years. The researchers focused two overlapping low-energy laser beams on a salt solution, which provided the exact right amount of energy to form a temporary crystal. Edinburgh professor Andy Alexander says the process could be used to improve on traditional methods of optical data storage such as CDs. In comparison to the two-dimensional surface of a CD, three-dimensional (3D) optical data storage contains far more layers, and tiny crystals could act as storage points. Information would be stored by making marks in a pattern and read using light. Alexander says that 3D, crystal-based devices could be available within 10 years and would enable users to easily store, access, and move massive amounts of data. “This research builds on a discovery that was made by accident many years ago, when it was found that light can be used to trigger crystal formation,” he says. “We have refined this technique and now we can create crystals on demand. There is much work to be done before these crystals can be used in practical applications such as optical storage, but we believe they have significant potential.”
