In JIT assembly system, any supplier’s postponement of delivery or incorrect delivery quantity will result in the manufacturer’s incapability of assembling on schedule, which will not only damage the interests of other suppliers but also jeopardize the interests of enterprises and reduce the competitiveness of the supply chain. In this article, coordination of the upstream supply logistics from...

We study asymptotic behavior in a class of non-autonomous second order parabolic equations with time periodic unbounded coefficients in R×R. Our results generalize and improve asymptotic behavior results for Markov semigroups having an invariant measure. We also study spectral properties of the realization of the parabolic operator u 7→ A(t)u − ut in suitable L spaces.

Community-based mass prophylaxis is a core public health operational competency, but staffing needs may overwhelm the local trained health workforce. Just-in-time (JIT) training of emergency staff and computer modeling of workforce requirements represent two complementary approaches to address this logistical problem. Multnomah County, Oregon, conducted a high-throughput point of dispensing (PO...

Synchronous Data Flow (SDF) is a popular model for analyzing workflows. It is well-known that self-timed scheduling, starting a task when all its prerequisites are satisfied, is throughput-optimal for SDF graphs. Just-in-time scheduling in the presence of deadlines has so far received little attention in the literature. We show that a feasible just-in-time schedule exists if and only if a feasi...

Among the suite of commonly used backbone experiments, HNCACO presents an unresolved sensitivity limitation due to fast 13CO transverse relaxation and passive 13Calpha-13Cbeta coupling. Here, we present a high-sensitivity 'just-in-time' (JIT) HN(CA)CO pulse sequence that uniformly refocuses 13Calpha-13Cbeta coupling while collecting 13CO shifts in real time. Sensitivity comparisons of the 3-D J...

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,...
