Although division is less frequent than addition and multiplication, because of its longer latency it dissipates a substantial part of the energy in floating-point units. In this paper we explore the relation between the radix and the energy dissipated. Previous work has been done on radix-4 and radix-8 division. Here we extend this study to a radix16 scheme with two overlapped radix-4 stages a...

In the high-speed collision between a baseball and bat, most of the initial center-of-mass kinetic energy is converted into compressional energy in the ball, and about 75% of that energy is dissipated. Some of the energy is stored in vibrational modes of the bat, particularly in the so-called “hoop modes”, the most important of which is a radial deformation with a quadrupole azimuthal dependenc...

The in situ rock undergoing different kinds of deformation accumulates elastic energy that can be released spontaneously o r under artificial effect. Triggering of energy can also be performed by means of a dynamic excitation caused by elastic waves. W e carried out special field investigations with the use of seismic vibrators (Vibroseis-like sources) to study the effect of the energy release ...

For a plant of average spectral properties and average diffusion resistance (2 sec/cm), diurnal variations in the energy dissipated by reradiation, convection, and transpiration have been explicitly calculated and plotted for certain environmental conditions as measured at St. Paul, Minnesota. These conditions represent the environments of characteristic types of days and of characteristic type...

Energy dissipation is an unavoidable phenomenon of physical systems that are directly coupled to an external environmental bath. In an oscillatory system, it leads to the decay of the oscillation amplitude. In situations where stable oscillations are required, the energy dissipated by the vibrations is usually compensated by replenishment from external energy sources. Consequently, if the exter...

PURPOSE To compare cumulative dissipated energy between two phacoemulsification machines. SETTING An ambulatory surgical center, Honolulu, Hawaii, USA. DESIGN Retrospective chart review. METHODS A total of 2,077 consecutive cases of cataract extraction by phacoemulsification performed by five surgeons from November 2012 to November 2014 were included in the study; 1,021 consecutive cases ...

Energy harvesting is a conventional method to collect the dissipated energy of a system. In this paper, we investigate the optimal location of a piezoelectric element to harvest maximum power concerning different excitation frequencies of a vibrating cantilever beam. The cantilever beam oscillates by a concentrated sinusoidal tip force, and a piezoelectric patch is integrated on the beam to gen...
