Spent Nuclear Fuel Self-Induced XRF to Predict Pu to U Content
The quantification of plutonium (Pu) in spent nuclear fuel is an increasingly important safeguards issue. There exists an estimated worldwide 980 metric tons of Pu in the nuclear fuel cycle and the majority is in spent nuclear fuel waiting for long term storage or fuel reprocessing. This study …

The political discourse of globalisation: globalising tendencies as self-induced external enforcement mechanisms
I begin with a critical deconstruction of the conventional wisdom of globalisation. If the world does indeed resemble that depicted in the conventional wisdom, the claim that policy change is structurally determined at the economic level could well be sustainable. However, I show that globalisation …

Predicting the Spatial Output Field of a Laser Beam in a Thermally Self-Induced Inhomogeneous Medium
Laser beam propagation in a thermally self-induced inhomogeneous medium is investigated to find the transient spatial output field for an arbitrary incident field. The paraxial wave equation is coupled with the heat diffusion equation to predict the beam output field as the index of refraction …

Selbstinduzierte Geschwindigkeitsoszillationin der Fahrzeugführung
This work is concerned with self-induced speed oscillations when driving a car. Although the driver is largely unaware of these variations, speed oscillates around a desired mean speed similarly a sine curve. While speed oscillations are often determined by the traffic situation (e.g. by a …

Estimation and Testing Methods for Monotone Transformation Models
… models as special cases. It develops a self-induced smoothing method for estimating the regression coefficients of these models, resulting in simultaneous point and variance estimations. The self-induced smoothing does not require bandwidth selection, yet provides the right amount of …

Cryogenic characterization of Josephson junctions
… are presented for use in analysis. The effect of self-induced magnetic field is considered. A numerical simulation is performed to justify neglecting effects of self-induced magnetic field in junctions of diameter less than the Josephson penetration depth Aj. Lincoln Laboratory's Josephson …

Slow and fast light by spectral hole-burning in the solid state
… as Rabi oscillations, free-induction decay and self-induced transparency (SIT). Switching between slow and fast light was obtained by transient hole-burning, which was reported for the first time. These results could pave the way to applications such as all optical switches. In addition, light …

Direct and Indirect Searches for Anomalous Beta Decay
… searches, focusing primarily on the concept of ``self--induce decay.'' This investigation stems from a series of recent reports that suggest that the decay rates of several isotopes may have been influenced by solar activity (perhaps by solar neutrinos). A mechanism in which (anti)neutrinos can …

Contributions Toward Understanding the Effects of Rotor and Airframe Configurations On Brownout Dust Clouds
… were also performed to examine the accuracy of self-induced velocities of vortex filaments by augmenting the straight-line vortex segments with a curved filament correction term. It was found that while curved elements can accurately recover the self-induced velocity in the case of a vortex …

A comprehensive study of the electrochemistry and floatability of pyrite in coal flotation
… pyrite from coal by flotation. They include self-induced hydrophobicity of pyrite caused by superficial oxidation, nonselective hydraulic entrainment of pyrite particles into froth product, and incomplete liberation of pyrite from coal that results in composite coal-pyrite particles, i.e., …

Crisis Management, Tourism and the Three Gorges Dam, China
… perspective, therefore, the Dam has become a ‘self-induced’ crisis for the Three Gorges area in general and for Three Gorges tourism. However, the Chinese government stresses that the Dam provides significant benefits to China’s economic development. The aim of this study is to identify …

Dynamic Instabilities in Structures with Nonholonomic Constraints
… examined. Within this setting, the Lorentz force induced is solely a property of the electric field as the magnetic induction field outside the solenoid vanishes. This property is known in electromagnetism as the 'Maxwell--Lodge effect'. The second investigation revisits Ziegler's double pendulum …

The Genesis and Evolution of African Easterly Waves
… centering at about 850 mb. The effect of the self-induced latent heating strongly depends upon the particular baroclinic structure. The growth rate, the propagation speed and the overall structure of the observed easterly waves (Reed et al., 1977) are well reproduced in the model.

The role of system dynamics on the behavior of elastomeric friction
Friction induced vibration of an epoxy coated shaft rotating in an elastomeric bushing is investigated. This study investigates the manner in which system dynamics and friction mechanisms are responsible for friction induced vibration and noise generation. A test method was developed to measure the …

Stable Spatial Solitons In Semiconductor Optical Amplifiers
A spatial soliton is a shape invariant self guided beam of light or a self induced waveguide. Spatial solitons appear as a result of the balance of diffraction and nonlinear focusing in a system. They have been observed in many different conservative media in the last couple of years. Solitons are …
