Deep-ultraviolet picosecond flat-top pulses by chirp-matched sum frequency generation

Christoph Peter Hauri

Picosecond, flat-top, deep-UV pulses are needed to generate high-brightness electron beams to efficiently drive x-ray free electron lasers. Current metal photocathodes have low efficiency and therefore require high-energy pulses, and the generation of high ...

Falling film evaporation on enhanced tubes, part 2: Prediction methods and visualization

John Richard Thome, Marcel Christians

For falling film evaporation, the most important thermal design parameters that need to be predicted are the onset of dryout, after which a severe degradation in the evaporator performance is found, and the local heat transfer performance in fully wet and ...

Intrinsic Emittance Reduction of an Electron Beam from Metal Photocathodes

Christoph Peter Hauri

Electron beams in modern linear accelerators are now becoming limited in brightness by the intrinsic emittance of the photocathode electron source. Therefore it becomes important for large scale facilities such as free electron lasers to reduce this fundam ...

Material-Based Object Segmentation Using Near-Infrared Information

Sabine Süsstrunk, Neda Salamati

We present a framework to incorporate near-infrared (NIR) information into algorithms to better segment objects by isolating material boundaries from color and shadow edges. Most segmentation algorithms assign individual regions to parts of the object that ...

Automatic Skin Enhancement with Visible and Near-Infrared Image Fusion

Sabine Süsstrunk, Daniel Tamburrino

Skin tones, portraits in particular, are of critical importance in photography and video, but a number of factors, such as pigmentation irregularities (e.g., moles, freckles), irritation, roughness, or wrinkles can reduce their appeal. Moreover, such “defe ...

Falling-Film Evaporation On Tube Bundle With Plain And Enhanced Tubes-Part Ii: New Prediction Methods

John Richard Thome, Mathieu Habert

Many parameters influence the falling-film evaporation process and, despite numerous studies, the basic mechanisms remain only partially clear, making the prediction of heat transfer still mainly an empirical process. The most important thermal design para ...
