Simple computer modeling of impulse responses for small rectangular rooms is typically based on the image source method, which results in an impulse response with very high time resolution. Image source method is easy to implement, but simulated impulse responses are often a poor match to measured impulse responses because descriptions of sources, receivers, and room surfaces are often too idea...

Impulse radio, a form of ultra-wide band signaling, has properties that make it a viable candidate for short range communications in dense multipath environments. This paper describes the characteristics of impulse radio, gives analytical estimates of its multiple access capability, and presents propagation test results and their implications for the design of the radio receiver.

An innovative and energy efficient sludge dewatering technology has been developed. The technology, impulse drying, involves briefly contacting the sludge under pressure with a heated surface. A unique feature of impulse drying is that the majority of moisture removal occurs as lipid water. A pilotand laboratory-scale demonstration was performed on low ash primary paper mill sludge. The pilot-s...

Water hammer wave is widely applied to test hydraulic components in various areas. A new high-pressure impulse generator presented this paper order provide the standard water for long-term usage. combination of a sleeve and rotary spool was used build generator, booster piston amplify output pressure. Mathematical models were established using commercial software, prototype rig built based on s...

Impulse is a memory system architecture that adds an optional level of address indirection at the memory controller. Applications can use this level of indirection to remap their data structures in memory. As a result, they can control how their data is accessed and cached, which can improve cache and bus utilization. The Impulse design does not require any modification to processor, cache, or ...

This study performs analytical investigation of how accurately three existing phase shift models describe the phase shift impulse response of a simple planar oscillator. The investigation finds that Kaertner’s model perfectly describes the behavior of the phase shift impulse response, whereas the projection-based ISF, and the perturbation projection-based model oversimplify it to its initial, a...

A Lagrangian numerical method based on impulse variables is analyzed. The relation between discrete impulse vectors and vortex dipoles with a prescribed dipole moment is presented and used to adapt the high-accuracy cutoo functions of vortex methods for use in impulse-based methods. The long-time implementation of the impulse method is shown to contain a source of error whose growth in time lea...

Limited frequency response of impulse voltage dividers contributes to the measurement errors of the peak voltage and time parameters. This paper investigates the convolution method for the determination of the errors of lightning impulse parameters due to non-ideal step responses. The step response of a damped capacitor divider with a voltage rating of 2.2 MV was measured and analytical lightni...
