Cattal Bridge. Cattal Bridge is a historic road bridge in Cattal, a village in North Yorkshire, in England.

The Roman road later known as Rudgate, connecting Tadcaster and Aldborough, crossed the River Nidd at Cattal, though it is not known whether there was a bridge or a ford.  A ford was in use in the Mediaeval period, being first recorded during the reign of Henry III of England.  A timber bridge was in existence by the mid-16th century, when it was recorded by John Leland.

The current bridge was built at the end of the 18th century, when embankments were constructed on the river.  It is 150 metres upstream from the line of the Roman road.  The north arch and parapets have been extensively repaired, but it has never been strengthened, and so retains its original features better than most other bridges of similar date.  The bridge underwent a £78,000 repair project in 2011, during which careful measures were taken to maintain the original character and shape of the bridge.

The bridge carries Cattal Moor Lane over the River Nidd.  It is built of limestone, and consists of three round arches with chamfered moulding.  The central arch is 15 metres wide, and the others each span 11 metres.  The bridge has triangular cutwaters, the piers rising to form refuges, and the parapet has flat coping.

The bridge was made a scheduled monument in 1976, and a Grade II listed building in 1985.

Energy signature. In mechanical engineering, energy signatures (also called change-point regression models) relate energy demand of buildings to climatic variables, typically ambient temperature. Also other climatic variables such as heating or cooling degree days are used. In most cases, heating or cooling building energy demand is analysed through energy signatures,  but also hot water or electricity demand is considered.

Energy signatures make a simplified assumption of a linear relationship between a building's energy demand and temperature. This assumption allows for balancing accuracy with computation time, as the estimation of energy demand through energy signatures is considerably faster than using building performance simulation software. A crucial advantage of applying energy signatures is that no detailed information on the geometrical, construction, and operational characteristics of buildings needs to be available.

William Curtin. William A. Curtin is an American materials scientist who is Elisha Benjamin Andrews Professor at Brown University in Providence, Rhode Island.

From 2011 to 2022, he was director of the Institute of Mechanical Engineering at École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland. He received a Guggenheim Fellowship in 2005.

His research interests span a wide range of topics in materials science and theoretical physics, including the mechanics of materials, multiscale modeling, and the properties of metal alloys and composites. He is the author of several high-impact publications in the field of materials science.

He was editor-in-chief of Modelling and Simulation in Materials Science and Engineering for more than ten years until 2016.

Curtin proposed a new model for the Portevin–Le Chatelier effect (PLC effect), which is based on the "single-atomic-hop motion of solutes from the compression to the tension side of a dislocation core." This model provides a predictive framework for understanding dynamic strain ageing (DSA) in these alloys, offering new insights into the microscopic interactions that lead to macroscopic material behaviors.

Events
 December 1: Charles-Émile Reynaud files a patent for his animated moving picture system Théâtre Optique. The patent was issued on 14 January 1889.  Reynaud in the 1888 patent: "The aim of the apparatus is to obtain the illusion of motion, which is no longer limited to the repetition of the same poses at each turn of the instrument, as is necessary in all known apparatus (Zootropes, Praxinoscopes, etc.), but Having, on the contrary, an indefinite variety and duration, and thus producing real scenes animated by unlimited development. Hence the name of Optical Theater given by the inventor to this apparatus" (translated from French).
 Date uncertain - Charles-Émile Reynaud creates the animated film Un bon bock (A Good Beer). It consisted of 700 individually painted 6 x 6 cm pictures in a 50 meter long flexible strip. Reynaud manipulated the speed and repeated movements by moving the film back and forth through the projector to tell a visual story that lasted close to fifteen minutes. The film would not be exhibited to the public until 1892.
