Model-Based Evaluation of Air-Side Fouling in Closed-Circuit Cooling Towers
Fouling is a permanent problem in process technology and is estimated to cost 0.25% of the gross national product. Evaporative cooling systems are especially susceptible to air-side fouling: as they work with untreated outside air, they are exposed to ...

A geostrophic-like model for large Hartmann number flows [PDF]
A flow of electrically conducting fluid in the presence of a steady magnetic field has a tendency to become quasi two-dimensional, i.e. uniform in the direction of the magnetic field, except in thin so-called Hartmann boundary layers.

Study of a MEMS-based Shack-Hartmann wavefront sensor with adjustable pupil sampling for astronomical adaptive optics [PDF]
We introduce a Shack-Hartmann wavefront sensor for adaptive optics that enables dynamic control of the spatial sampling of an incoming wavefront using a segmented mirror microelectrical mechanical systems (MEMS) device.

Reconstruction of coherence matrix in x-representation using nonclassical Hartmann sensor [PDF]
We show the coherence properties of a signal can be measured by a Hartmann wavefront sensor in a nonclassical regime. Recasting the detection theory of the classical Hartmann sensor in the sense of quantum tomography enables to measure the coherence ...

Effects of Laparoscopic Hartmann Reversal on Short-term Operative Outcomes Among Vietnamese Patients
Background The reestablishment of continuity after Hartmann operation is considered a major surgical procedure with high morbidity and mortality. The optimal interval time between the Hartman procedure and reversal is controversial.
