Decoding the ancient Greek astronomical calculator known as the Antikythera Mechanism
The Antikythera Mechanism is a unique Greek geared device, constructed around the end of the second century bc. It is known that it calculated and displayed celestial information, particularly cycles
The development of a high-precision microfocus X-ray computed tomography and digital radiography system for industrial applications.
This paper describes the design and development of a high-precision microfocus X-ray inspection system for ultra-high resolution 3-D computed tomography (CT) and 2-D realtime radiography for a wide
New software protocols for enabling laboratory based temporal CT.
Two new software protocols that enable temporal CT using commercial laboratory CT systems are presented, one of which drastically reduces the need for periodic intervention when making time-lapse experiments, and the other allows the number of projections in a reconstruction to be changed as sample evolution occurs.
Improved X-ray computed tomography reconstruction of the largest fragment of the Antikythera Mechanism, an ancient Greek astronomical calculator
The Antikythera Mechanism is an extraordinarily complex ancient Greek astronomical calculating device whose mode of operation is now relatively well understood particularly since imaging studies in
The Influence of Data Filtering on Dimensional Measurements with CT
The results of industrial dimensional CT measurements obtained at the same data set of a calibrated reference standard – a calotte cube – when using different filters are compared and the implications are discussed.
The latest techniques reveal the earliest technology – A new inspection of the Antikythera Mechanism
In the National Archaeological Museum in Athens sit the r emains of a remarkable machine, 1600 years ahead of its time. The Antikythera Mechanism, found on an ancient Greek shipwreck in 1901 is
X-ray Tomography of the Antikythera Mechanism
An "in-depth" explanation of how X-ray tomography r evealed the secrets of the world's most ancient astronomical calculator, this talk will des cribe how X-Tek Systems Ltd, at the time a small
The pocket-watch
This book records the excavation of the wreck of a small Cromwellian warship, believed to be Swan, which was found off Duart Point in 1979. When erosion threatened the site in 1992 maritime
Antikythera Mechanism shows evidence of lunar calendar
Based on statistical analysis of micro CT imaging of the more than 2,000-year-old Antikythera Mechanism, we show unexpected evidence establishing a lunar calendar with Egyptian civil-calendar
