The Bottle-Pipe Resonator

Silica Bottle Resonator Sensor for Refractive Index and Temperature Measurements

We propose and theoretically demonstrate a bottle resonator sensor with a nanoscale altitude and with alength several of hundreds of microns made on the top of the fiber with a radius of tens microns for refractive index and temperature sensor applications. The whispering gallery modes (WGMs) in the resonators can be excited with a taper fiber placed on the top of the resonator. These sensors c...

‘Solomon’s Bottle’: a Glass Bottle in Tehran and Abbasid Glass Floors in Mesopotamia and the Levant

The article discusses a scarcely known medium of architectural decoration in Abbasid palaces, transparent glass tiles, and reports on the discovery of the largest known assemblage of fragments of such tiles in Tehran, in a bottle of the Glassware and Ceramics Museum of Iran.  The first part deals with the visual and material aspects of the use of transparent glass tiles, based on archaeologica...

The Bottle of Medicine Habit

In-Pipe Inspection Crawler Adaptable to the Pipe interior Diameter

One of the most important requirements of repairing and maintaining of pipelines is the ability to monitor and evaluate the pipe’s interior. In this paper, a novel apparatus to traverse pipes is introduced. The mechanism employs three independent rubber track units which are circumferentially spaced out 120 degree apart symmetrically. The apparatus employs an active mode to adapt to a wide rang...
