Travel Demand Forecasting: Parameters and Techniques

Intrusive and non-intrusive watermarking

“Can we watermark without perturbing an image?” We present the salient results of the investigation carried out to find an answer to this question.

Non-intrusive temperature measurement using microscale visualization techniques

The ‘‘nano-particle image velocimetry’’ technique uses evanescent-wave illumination generated by total internal reflection at the wall to excite colloidal neutrally buoyant fluorescent tracer particles. The displacement of these particles over time as they are convected by the flow then gives the flow velocity components tangential to the wall. Since the extent of the illumination region normal...

Non-Intrusive Temperature Measurements Using Microscale Visualization Techniques

μPIV is a widely accepted tool for making accurate measurements in microscale flows. The particles that are used to seed the flow, due to their small size, undergo Brownian motion which adds a random noise component to the measurements. Brownian motion introduces an undesirable error in the velocity measurements, but also contains valuable temperature information. A PIV algorithm which detects ...

Combination Forecasts of Tourism Demand

This study investigates the performance of combination forecasts in the context of international tourism demand. Five econometric and two time-series models are employed to generate individual forecasts. Six combination methods are then employed, and their forecasting performance evaluated, using data on UK outbound tourism demand in seven destination countries. The results suggest that combina...
