We have extended OWL-Time to support the encoding of temporal position in a range of reference systems, in addition to the Gregorian calendar and conventional clock. Two alternative implementations are provided: as a pure extension or OWL-Time, or as a replacement, both of which preserve the same representation for the cases originally supported by OWL-Time. The combination of the generalized t...

The Egyptian state was formed prior to the existence of verifiable historical records. Conventional dates for its formation are based on the relative ordering of artefacts. This approach is no longer considered sufficient for cogent historical analysis. Here, we produce an absolute chronology for Early Egypt by combining radiocarbon and archaeological evidence within a Bayesian paradigm. Our da...

In East Timor’s diversified subsistence economy, rice and maize are today common staples in some areas but root crops and arboriculture, too, play an important role. Although a cultural and chronometric framework for the introduction of agriculture in East Timor has long been proposed, little is known about the exact history of early plant use in the island. This paper deals with preliminary fi...

The high-precision unification of global height datum has long been a hot issue in the field geodesy. chronometric leveling method originates from gravitational redshift effect general relativity, which may provide new solution for datum. difference between two locations could be measured via frequency comparison optical clocks. We build error model leveling, mainly including measurement system...
