More efficient combinations of web services through mobile channels

31.01.2007
The 'mobile channels' software concept allows services on the web to be combined more flexibly and efficiently. How mobile channels work is described by Dutch researcher Juan Guillen Scholten in his PhD thesis 'Mobile Channels for Exogenous Coordination of Distributed Systems'.

Over the past few years there has been a growing interest among computer scientists and users for distributed computer systems such as the Internet. A distributed system consists of different independent computers in a network that appears to be a single coherent system for the users. At least one software component is present on each computer, which communicates with components that are on other computers, such as databases, web services or peer-to-peer applications that exchange data such as Skype, Kazaa or Napster. As all of these components are distributed and run at the same time, suitable theories and infrastructures are needed for an efficient coordination.

Guillen Scholten developed the MoCha coordination framework that consists of both models and software. It is capable of coordinating components from the outside (exogenously). As a result of this MoCha can change the behaviour of the system without needing to adjust the software components. It can also dynamically change the links between components. This characteristic is particularly useful when the components are mobile. MoCha can be used efficiently on Grids, in service-oriented architectures (SOAs), component-based software and in-home networks.

The National Research Institute for Mathematics and Computer Science (CWI) is the national research institute for mathematics and computer science. It is a research institute of NWO. For further information see www.cwi.nl.

Juan Guillen Scholten's research was funded by NWO.

New technique promises tunable laser devices

Whispering gallery mode (WGM) resonators are used to make tiny micro-lasers, sensors, switches, routers and other devices. These tiny structures rely on a...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
