Development of a Participative Approach to Guide Organizational Change: Reviewing the Sawtooth Technique
In a world economy that bears scant resemblance to the one dominated by the United States following World War II, many American companies have found it increasingly difficult to keep pace with their foreign competitors. The public sector, too, has found itself under significant pressure to provide …

DEVELOPMENT OF THE ROCKY MOUNTAIN FORELAND BASIN: COMBINED STRUCTURAL, MINERALOGICAL, AND GEOCHEMICAL ANALYSIS OF BASIN EVOLUTION, ROCKY MOUNTAIN THRUST FRONT, NORTHWEST MONTANA
… of the Middle Jurassic (Bajocian-Bathonian) Sawtooth Formation (~170 Ma). Fieldwork established that northwest-trending, karst-widened fractures (grikes) are filled with cherty, phosphatic sandstone and conglomerate of the Sawtooth Formation and penetrate the Madison Group for 4 meters below …

On the use of switched-capacitor multi-level inverters for electro-aerodynamic thrust applications
… thrust to DBD power for a sine wave and sawtooth wave were >76% higher than for a pulse wave, and >19% higher than for a square wave, indicating that a sine or sawtooth wave generating circuit such as a SCMLI may be a good choice for EAD flight applications.

Finite element analysis of shear resistant mechanisms for biolaminate interfaces
… a stiff outer ganoine layer, a characteristic "sawtooth" pattern at the interface and a compliant bone inner layer with all materials exhibiting a decreasing elastic modulus, yield strength and density through the thickness. Experiments on ganoid scales revealed properties such as damage …

Optimizing Snake Locomotion on a Plane: A Variational and Analytical Framework for Friction and Normal Force Modulation
… forward displacement. The results show that sawtooth-shaped body waveforms—characterized by alternating constant body angles—achieve optimal efficiency and velocity. In anisotropic environments, where transverse friction dominates, lateral undulation is both energetically favorable and …

Thermal helium buildup and control in a fusing tokamak
… the ash from there. It is found that the optimal sawtooth period to give minimum ash level (or maximum fusion power) is several times larger than the fast alpha slowing down time for the ARIES-I type driven plasma. With sawtooth period $\sim$5 seconds and helium transport selectively enhanced by …

Suboptimal period design for a maneuvering missile to evade tracking filters
… and of specific types (sinusoidal, square and sawtooth waveforms); therefore, the periods which minimize the EHITS in this study are suboptimal for the general engagement problem. Two methods are used to obtain the suboptimal periods: one is the ”brute force" method of computing the EHITS for …

False lock in sampled-data phase lock loops
… lock loop containing a phase detector with a sawtooth characteristic are investigated. The ideal processor of data operated on by such a phase detector nonlinearity is derived in open-loop form. A second system is proposed which is shown to approximate the operation of the ideal system with …

STM Studies of Oxygen Etching of Silicon Surfaces
… Si(5 5 12) and Si(112). These surfaces form sawtooth facets that are primarily composed of more stable (111) and (113) planes. By controlling the temperature and exposure during oxygen etching, it is therefore possible to form a variety of surface morphologies.

Experimental Design and Analysis of Piezoelectric Synthetic Jets in Quiescent Air
… found to be the most important factor, with the sawtooth signal producing significantly higher velocities than the sine signal. Cavity dimensions also proved to be relevant factors when considering the designing of a synthetic jet actuator. The cavities with the smaller orifice produced lower …

Disruption mitigation and real-time detection of locked modes
… procedure has been written which detects the ECE sawtooth suppression by calculating changes in the standard deviation of the signal over a moving time-window. This procedure has been programmed into the digital plasma control system (DPCS) for real-time testing. The procedure successfully located …

Convertible Parks: New Architectural Strategies for Public Parks in a Changing Climate
… opportunities throughout the year. Specifically, sawtooth roofs, brise soleil, and vegetation are explored to manage temperatures, light, and airflow.

Understanding the Impact of a Serrated Trailing Edge on the Unsteady Hydrodynamic Field
… experiments have shown that a trailing edge with sawtooth serrations can reduce trailing edge noise compared to a straight trailing edge, but the mechanism by which sawtooth serrations reduce noise is not fully understood. Previous theoretical models have assumed that the turbulence field …

Experimental study of current-driven turbulence during magnetic reconnection
… enabling deleterious instabilities, such as the sawtooth instability in fusion experiments, to transport plasma across the experiment's minor radius. Notably, simple estimates of the finite reconnection rate due to classical resistivity fail to explain the fast and explosive nature of …

Microfabricated magnetophoretic focusing systems for the separation of submicrometer particles
… core elements. The systems produced "sawtooth" magnetic fields that were combined with a long-range magnetic field or pressure- driven flow to bring about migration, focusing and trapping of nonmagnetic particles suspended in ferrofluid. A potential application of such systems is …

Coherent control of quantum information
… schemes. A quantum simulation of the quantum sawtooth map in the perturbative parameter regime is used to study the effects of experimental noise on quantum localization, a highly sensitive quantum interference phenomenon that depends on the coherence of the localized state. Experimental data …

DNA translocation through an array of kinked nanopores
… a coarse-grained drift-diffusion theory with a sawtooth like potential can reasonably describe the velocity and translocation time of DNA through the pore. By control of pore size, length, and shape, we capture the major functional behaviors of protein pores in our solid-state nanopore system.'

Quantitative study on current-induced effects in an antiferromagnetic insulator/Pt bilayer film
… memory devices and obtained a similar sawtooth-like behavior. Using the uniquely small spin-flop field of [alpha]-Fe2O3, we compared the current-induced Hall resistance to the field-induced one, and analyzed the nature of the switching. We raise the concern that the signal in these …
