This paper describes the development of a data mining system that is to operate on NASA’s Information Power Grid (IPG). Mining agents will be staged to one or more processors on the IPG. There they will grow using just-intime acquision of new operations. They will mine data delivered using just-in-time delivery. Some initial experimental results are presented.

We compare two recent astrobiological approaches to the solution of the problem of the “Great Silence” (or Fermi’s paradox): the “rare Earth” hypothesis of Ward and Brownlee, and the phase-transition scenario of Annis. We show that they have important similarities, as far as self-selection of intelligent observers is concerned. In order to better illuminate the differences, we consider the dura...

Most just-in-time compilers for object-oriented languages operate at the granularity of methods. Unfortunately, even “hot” methods often contain “cold” code paths. As a consequence, just-in-time compilers waste time compiling code that will be executed only rarely, if at all. We discuss an alternative approach in which only truly “hot” code is ever compiled.

Ein verbreitetes Problem beim Unterrichten von Software-Engineering ist, dass den Studierenden die Erfahrung mit großen, realen Softwaresystemen fehlt. Dadurch wird die Sinnhaftigkeit der vorgestellten Methoden nicht ausreichend erkannt. Wir versuchen, die fehlende Erfahrung zu simulieren und haben dazu die Methode des Justin-Time Teaching (JiTT), in Form von Quiz, eingeführt. Die Studierenden,...

Due to increasing globalization, businesses are managing global supply chains. Information technology and the internet have introduced new market opportunities. Increases in productivity and increasing cost pressures from global competition have introduced just-in-time manufacturing and assembly. The trucking industry, which moves over three-quarters of the country’s freight, has had to adapt t...

Workplace training is most effective when the training happens just in time as part of a worker’s regular job activities. We are developing a just-in-time training system called PHelpS (Peer Help System) which can select peer helpers with whom the worker can interact. User modelling is central in the PHelpS system. For each worker, a user model is kept containing several kinds of information ab...

In view of strong competitive markets, current companies tend to new methods of production, from a logic of «planning» type of production to a logical of «Just in time » type. In this context, the system that allows controlling the production has to be a modular, flexible and reactive system. The hierarchized and classical approaches don’t permit any more to take into account the complexity lin...

We introduce and study the range contract, which allows a buyer to procure from a supplier at a prescribed price any amountwithin a specified range. In return, the supplier is compensated up front for thewidth of the rangewith a range fee. This fee canbe viewed as the buyer tradingmonetary value for reduceduncertainty. The range contract generalizes and unifiesmany common contracts, such as fix...

I believe that education is an investment for the future of society. To develop our society we need to achieve the best education for every individual through providing every appropriate means for the particular individual. To provide the best education for each individual, we must perforce adapt our education to the individual. One adaption is to free the individual constraints of place and ti...
