Dislocation
Price dislocations are common in fixed-income markets. I propose a dislocation factor (DIS), the first principle of three fixed-income market dislocations, including covered interest parity, on/off the run spread, and treasury noise measure. DIS surges when the market is under stress and indicates …

Quantifying Dislocation Microstructures
… work, we reconstructed and full characterized a dislocation microstructure that formed during an in situ micro-cantilever beam experiment. Based on this information, we were then able to infer how the dislocations propagated from the notch into the specimen. We propose using the so-called …

Arrival / departure : architecture of dislocation
Our identities are defined by a qualitative set of parameters that are at once universal and site specific. We are, as an old saying puts it, "products of our environment." Our knowledge and our beings are constantly being tested and changed through our interactions, both physical and cerebral, in …

Dislocation -Obstacle Interactions in Aluminum Alloys
This thesis examines two types of dislocation-obstacle interactions: dislocation-particle interactions during creep deformation, and dislocation-loop interactions during deformation at room temperature. Dislocation-particle interaction studies in Al-Zn-Mg-Cu-Zr, Al-4Mg-0.3Sc, and Al-0.3Sc showed …

Plastic Instability Due to Collective Dislocation Effect in Portevin-Le Châtelier Effect and Dislocation Nucleation
… (PLC) effect and the cooperative nucleation of dislocation loops, have been studied. In the experimental part of the work, two creep-type mechanical tests have been conducted on a Cu-10at.%Al single crystal and a Mg single crystal to study the plastic instability in the PLC effect and …

Dislocation and Adjustment of International Student-Athletes
<p>One reason that attracts international student-athletes to American universities could be the interest in earning high quality education with the possibility of playing high performance sports. However, when compared to other international students, differences are seen: Other foreign students …

Neural injury following traumatic anterior shoulder dislocation
… with brachial plexus lesions caused by shoulder dislocation. As far as can be established, this is the largest series reviewed in the literature to date. Contrary to most other reports, the neurological lesions involved the supraclavicular as well as the infraclavicular brachial plexus. The only …

Atomistic and mesoscale modeling of dislocation mobility
Dislocation is a line defect in crystalline materials, and a microscopic carrier of plastic deformation. Because dislocation has both a localized core and a long-range stress field, linking atomistic and meso scales is often the most challenging step in studying its dynamics. This Thesis presents …

Statistical physics of dislocation nucleation by nanoindentation
… of crystalline materials involves homogenous dislocation nucleation in the crystal underneath the indenter. Through the use of cutting-edge nanoindentation techniques, this study examines the initiation of plastic deformation in single crystal oriented platinum samples. Variations in the …

Bias stress detection of dislocation resonance in lead

Modeling dislocation density evolution in continuum crystal plasticity
Dislocations are the singly most important material defects in crystal plasticity, and although dislocation mechanics has long been understood as the underlying physical basis for continuum crystal plasticity formulations, explicit consideration of crystallo- graphic dislocation mechanics has been …
