conclusions in this case, after failure of awake fiberoptic intubation, awake direct laryngoscopy and blind nasal intubation, finally awake nasal intubation in sitting position, using fiberoptic led to success. case presentation the present case discusses a patient with severe deformity of mandible that was admitted for correction with free-flap. the following intubation techniques were used fo...

Fiber optic sensor technology offers the possibility of sensing different parameters like strain, temperature, pressure in harsh environment and remote locations. these kinds of sensors modulates some features of the light wave in an optical fiber such an intensity and phase or use optical fiber as a medium for transmitting the measurement information. The advantages of fiber optic sensors in c...

Infrared detectors can be used for a variety of applications such as: using in fiber-optic communications. Conventional technology for IR detectors is using p-i-n structure based on GaAs compound. This paper reports on the design and modeling of an IR detector using a p-i-n GaAs structure. Comsol software is used to simulate the model and the detector is discussed for terminal current, dopant p...

The monitoring of transportation infrastructure health is currently reliant on transportation maintenance teams. Scheduled and periodic inspections of most infrastructures are performed by manual and visual operations, which are generally time consuming and costly procedures. The use of fiber-optic sensor technology makes it possible to realize continuous, real-time and automatic health monitor...

Fiber optic interferometry can be broadly explained as the techniques that utilize the fundamental principles of optical interference to measure physical sample properties or detect changes via sensing systems that are partially or completely realized using fiber optic components. While the field of optical interference dates back to second half of seventeenth century, the advent of fiber optic...
