Weather Prognostics in Anglo-Saxon England

Prognostics concerning the day of the week on which kalendae ianuariae and Christmas Day fall, commonly known as the Revelatio Esdrae , purport to be a set of prophecies by the Biblical Esdras. They make predictions about the weather and other natural phenomena for the year to come, and they then extend their predictions to the field of human affairs. A remarkable number of copies of the Revelatio appear in English manuscripts from the tenth to the twelfth centuries. Some of these versions have been attributed to Bede and Abbo of Fleury as part of their computus works.

Both R. M. Liuzza and L. S. Chardonnens point out the frequent occurrence of the Revelatio in religious and scientific manuscripts and therefore reject the label of folklore, stressing instead the probable monastic origin of this prognostication. This study will provide the first complete collation and analysis of the surviving exemplars, to give as full an idea as possible of their circumstances of composition, their transmission, and their relationship to one another. It will consider how the Revelatio Esdrae was copied and used in Anglo-Saxon England, the audience to which it was addressed, and whether any conclusion can be drawn from its appearance in particular manuscripts, alongside certain other texts.

The regular occurrence of the Revelatio along with computistical material supports the case for its monastic origin and learned nature. Such a text would have been a helpful handbook to be used by monks and priests, and was among the standard holdings of continental and Anglo-Saxon monasteries and scriptoria, giving further proof of the monks’ intellectual eclecticism and their knowledge of the kinds of continental literature from which this text derives.

In situ diagnostics and prognostics of solder fatigue in IGBT modules for electric vehicle drives

This paper proposes an in situ diagnostic and prognostic (D&P) technology to monitor the health condition of insulated gate bipolar transistors (IGBTs) used in EVs with a focus on the IGBTs' solder layer fatigue. IGBTs' thermal impedance and the junction temperature can be used as health indicators for through-life condition monitoring (CM) where the terminal characteristics are measured and the devices' internal temperature-sensitive parameters are employed as temperature sensors to estimate the junction temperature. An auxiliary power supply unit, which can be converted from the battery's 12-V dc supply, provides power to the in situ test circuits and CM data can be stored in the on-board data-logger for further offline analysis. The proposed method is experimentally validated on the developed test circuitry and also compared with finite-element thermoelectrical simulation. The test results from thermal cycling are also compared with acoustic microscope and thermal images. The developed circuitry is proved to be effective to detect solder fatigue while each IGBT in the converter can be examined sequentially during red-light stopping or services. The D&P circuitry can utilize existing on-board hardware and be embedded in the IGBT's gate drive unit.

NIGHT FLIGHT ACROSS A BLUE SKY: PROGNOSTICS

The purpose of this presentation is to gain new perspectives on pest control and related phenomena. Some will call it “blue sky.” I would claim it informal futuristics. Systems men call such efforts feedforward; others grandify it with “prognostics.” Some say prognostics is one of the leading challenges of the day. We must anticipate future developments and imagine or invent new alternatives as a background for rational choice. The activity can influence today’s decisions, modify our concepts of risks and probable payoffs, and can help those of us who ask: “What am I really doing; what should I be doing?”
