Just-in-time, just-enough-time and horizon signalling protocols on optical burst switches

Optical burst switch (OBS) is considered to be a promising switch technology for the future network. In this paper, just-in-time (JIT), just-enough-time (JET) and horizon signalling schemes for OBS are presented. These signalling schemes run over a core dynamic wavelength division multiplexing (DWDM) network. The network is proposed to support IP, ATM and burst traffic. We apply the Poisson and...

Just Enough Requirements Traceability

Even though traceability is legally required in most safety critical software applications and is a recognized component of many software process improvement initiatives, organizations continue to struggle to implement it in a cost-effective manner. This panel addresses the problems and challenges of requirements traceability and asks questions such as “How much traceability is enough?” and “Wh...

Just Enough Likelihood∗

Statisticians have developed several methods for comparing hypotheses and for estimating parameters from data. Of these, the method of maximum likelihood is remarkable both for its power and for its flexibility. Yet it is seldom covered in introductory statistics courses because it is hard to present either as a canned computer program or within a cookbook-style textbook. It is much too flexibi...

Pichia pastoris "just in time" alternative respiration.

Alternative oxidases (Aox or Aod) are present in the mitochondria of plants, fungi and many types of yeast. These enzymes transfer electrons from the ubiquinol pool directly to oxygen without contributing to the proton transfer across the mitochondrial membrane. Alternative oxidases are involved in stress responses, programmed cell death and maintenance of the cellular redox balance. The altern...
