Claims first made over half a century ago that certain prehistoric monuments utilised high-precision alignments on the horizon risings and settings of the Sun and the Moon have recently resurfaced. While archaeoastronomy early on retreated from these claims, as a way to preserve the discipline in an academic boundary dispute, it did so without a rigorous examination of Thom’s concept of a “lunar standstill”. Gough’s uncritical resurrection of Thom’s usage of the term provides a long-overdue opportunity for the discipline to correct this slippage. Gough (2013), in keeping with Thom (1971), claims that certain standing stones and short stone rows point to distant horizon features which allow high-precision alignments on the risings and settings of the Sun and the Moon dating from about 1700 BC. To assist archaeoastronomy in breaking out of its interpretive rut and from “going round in circles” (Ruggles 2011), this paper evaluates the validity of this claim. Through computer modelling, the celestial mechanics of horizon alignments are here explored in their landscape context with a view to testing the very possibility of high-precision alignments to the lunar extremes. It is found that, due to the motion of the Moon on the horizon, only low-precision alignments are feasible, which would seem to indicate that the properties of lunar standstills could not have included high-precision markers for prehistoric megalith builders.

For nearly 270 years, between the end of the Roman Empire and the advent of the Carolingian dynasty, the Merovingian territories experienced an intense flowering of religious construction, which recent archaeology has documented with increasing detail. This chapter sheds light on new research and recent discoveries; however, rather than reviewing all of the sites and studies of Merovingian churches and the contemporary sources mentioning them, it gives some new clues and reflections about so-called Merovingian architecture and the broad vision of an architectural form that was expressed in quite simple but majestic designs. These structures, constructed of stone (or wood), reveal a society progressively Christianized under the leadership of bishops, clerics, and monks, as well as by the Merovingian sovereigns. Without any break with classical antiquity, the Merovingian centuries fit into a continuous legacy that transformed the monumental landscape in both cities and countryside. The various forms of Christian monuments of the fifth to eighth century thus illustrate this heritage, sometimes through an extreme simplification of antique patterns and sometimes through the enrichment of aesthetic forms brought by the arrival of immigrant populations. Within a changing world, religious buildings appear to have been a catalyst for cultural exchanges as places of visibility and gathering, as witnesses of the building fever of the period. Our understanding of religious architecture in Merovingian Gaul is gradually becoming more accurate. We now know an increasing amount about the establishment, planning, forms and sizes, construction techniques, ornamentation, and liturgical and functional content of all these structures. These structures, which were so varied in size and use, reveal extensive artistic plurality.

In this paper, we present the concept of the Radio Environment Map (REM) designed to ensure electromagnetic situational awareness of cognitive radio networks. The map construction techniques based on spatial statistics are presented. The results of field tests done for Ultra High Frequency (UHF) range with different numbers of sensors are shown. Exemplary maps with selected interpolation techniques are presented. Control points where the signal from licensed users is correctly estimated are identified. Finally, the map quality is assessed, and the most promising interpolation techniques are selected.
