Aramaic receipts and title-deeds on clay tablets are formally distinguished in the 7th century B.C., although they are closely related juridical documents. Only two receipts are known at present and both have a triangular shape like loan contracts. Instead, titledeeds, often called sale acts, have a rectangular shape and are narrowest along the lines of writing. They are sealed on the upper edge of the tablet or in the upper part of the obverse. So far, there is only one Aramaic title-deed concerning a field and a second one fixing the boundary between two properties. Instead, four or five deeds concern the acquisition of persons, not necessarily slaves. Considering the state of the clay tablets and their somewhat inadequate edition, a new transliteration and translation of the operative parts of the deeds are provided below, omitting the lists of witnesses. Short comments are proposed also for the fragment of a title-deed dated in the 34th year of Nebuchadnezzar II.
The paper presents the problem of building disturbances, which are usually an inseparable element during the implementation of construction projects. They were classified, their causes and sides of the construction process responsible for their creation were identified on the basis of the analyzed construction investment. In addition, using the Earned Value Management method, the scale of delays arising in construction works and the related effects were determined. The important role of close cooperation and good communication between all participants of the construction process was emphasized, which would reduce the phenomenon of building disturbances, but also mitigate the negative effects of delays that have already occurred.
This article proposes and examines a solution in which the base-station for the fifth generation radio access network is simplified by using a single millimeter-wave oscillator in the central-station and distributing its millimeter-wave signal to the base-stations. The system is designed in such a way that the low-phase-noise signal generated by an opto-electronic oscillator is transmitted from the central-station to multiple base-stations via a passive optical network infrastructure. A novel flexible approach with a single-loop opto-electronic oscillator at the transmitting end and a tunable dispersion-compensation module at the receiving end(s) is proposed to distribute a power-penalty-free millimeter-wave signal in the radio access network. Power-penalty-free signal transmission from 10 MHz up to 45 GHz with an optical length of 20 km is achieved by a combination of a tunable dispersion-compensation module and an optical delay line. In addition, measurements with a fixed modulation frequency of 39 GHz and discretely incrementing optical fiber lengths from 0.625 km to 20 km are shown. Finally, a preliminary idea for an automatically controlled feedback-loop tuning system is proposed as a further research entry point.
