An Overview of the Use of Absolute Dating Techniques in Ancient Construction Materials
The reconstruction of the chronology of historical buildings is a tricky issue, as usually there are not historical documents that allow the assessment of construction phases, and some materials are hardly reliable for the use of dating techniques (e.g., stone). However, in the last two decades, important advances on the use of absolute dating methods on building materials have increased the po...
متن کاملrelative and absolute dating of tepe sagzābad, qazvin plain
sagz?b?d mound was one of the first areas excavated in the course of archeological surveys conducted by the university of tehran in qazvin plain. findings indicate its permanent establishment since the end of the third millennium up to the mid-first millennium b.c.; however, during the recent explorations made by the university of tehran in october and november 2008, absolute dating was carried...
متن کاملLifting and recombination techniques for absolute factorization
In the vein of recent algorithmic advances in polynomial factorization based on lifting and recombination techniques, we present new faster algorithms for computing the absolute factorization of a bivariate polynomial. The running time of our probabilistic algorithm is less than quadratic in the dense size of the polynomial to be factored.
متن کاملUnusual techniques for absolute distance measurement
Peter de Groot Zygo Corporation Research and Development Department 21 Laurel Brook Road Middlefield, Connecticut 06455 Abstract. I describe four unusual laser systems for absolute measures of linear distance. All employ the familiar techniques of multiple wavelengths, chirped wavelength, optical feedback and intensity modulation, but in somewhat unfamiliar architectures. These examples serve t...
متن کاملAn absolute chronology for early Egypt using radiocarbon dating and Bayesian statistical modelling.
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...
