Boiler Drum-level Modeling
In this paper, a mathematical model is developed to describe the dynamics of the drum-level of a natural circulation boiler. A boiler-drum is divided into two parts; the upper part contains saturated steam while the lower part contains a steam/water mixture. The ratio of the steam in that mixture is defined in this work as the steam volumetric ratio. On the other hand, balance equations are app...
متن کاملDoes the Catford drum give an accurate assessment of acuity?
Adult emmetropes and myopes were tested with the Catford drum and the results compared with subjective (Landolt C) acuity. For he emmetropes the Catford drum was found to overestimate visual acuity by a factor of approximately 4. For myopes, and emmetropes viewing through plus lenses, the discrepancies were much larger. Since the Catford drum not only overestimates acuity but will do so by a fa...
متن کاملControl of Drum Boiler Dynamics via an Optimized Fuzzy Controller
Drum Boilers are an important component of many modern industrial facilities. Generally, the simulation of tailormade Drum Boilers starts up at each steady-state condition inside each operation region. The problem of such systems is the control of parameters, as level and pressure, around a reference value. The design of control algorithms can be accomplished using intelligent techniques such a...
متن کاملDigital Drum Tutor
This thesis investigates issues surrounding the design and implementation of a digital drum tutor. People have been developing digital tutors in all fields of study in an attempt to replace or complement human instructors. This drum tutor aims to replace a human instructor in some cases, but mostly to guide a student’s practice sessions, which is where the most improvement occurs. While using t...
متن کاملThe Evolving Drum Machine
The expectation of the listener from house and techno music seems to be that percussion sounds will maintain the same timbre for the duration of a piece of music. For the composers of such musics the synthesizing of drum sounds of a quality equal to those available from commercial drum machines or samples is difficult and seems unnecessary. A system is presented here which provides a unique met...
