Abstract Side weirs are widely used in hydraulic engineering applications. The studies on the subject have been generally focused classical and labyrinth side weirs. However, same is not true for piano key (PKSW) a straight channel. weir (PKW) has high discharge capacity compared with In this study, characteristics of trapezoidal (TPKSW) channels were investigated experimentally. all experiment...

This paper proposes novel computer-based interfaces for piano practicing. They are designed to display in real time certain well-defined sub-aspects of piano playing. They are intelligent and unobtrusive in that they adjust automatically to the needs of the practitioner so that no other interaction is needed than moving the piano keys. They include 1) a pattern display, finding recurring pitch ...

Two related versions of an unstable live algorithm for the Disklavier player piano are presented. The underlying generative feedback system consists of four virtual musicians, listening to each other in a circular configuration. There is no temporal form, and all parameters of the system are controlled by the performer through an intricate but direct mapping, in an attempt to combine the experi...

This study investigated the temporal behavior of grand piano actions from different manufacturers under different touch conditions and dynamic levels. An experimental setup consisting of accelerometers and a calibrated microphone was used to capture key and hammer movements, as well as the sound signal. Five selected keys were played by pianists with two types of touch ("pressed touch" versus "...

Run-of-river hydropower plants usually lack significant storage capacity; therefore, the more adequate control strategy would consist of keeping a constant water level at the intake pond in order to harness the maximum amount of energy from the river flow or to reduce the surface flooded in the head pond. In this paper, a standard PI control system of a run-of-river diversion hydropower plant w...

The Natural Resources Conservation Service (NRCS) has assisted local sponsors with analysis, design and construction of approximately 26,000 of the 80,000 dams in the National Inventory of Dams. Many of these dams are reaching their design life and require rehabilitation. Rehabilitation efforts come at a time when NRCS is in the process of evaluating a potential change from a minimum 6-hour sto...

OBJECTIVE To report a patient with genetically proven DYT1 dystonia who shows dramatic improvement in symptoms while playing the piano. DESIGN Case study. SETTING Sobell Department for Motor Neuroscience and Movement Disorders, Institute of Neurology, University College London, England. PATIENT A 49-year-old right-handed male civil servant. MAIN OUTCOME MEASURES The patient was videotap...
