Authors: Cao Jing , Wang Xiao Yong , Zuo Huai Xi , Liu Hai Ming , Zheng Wen Wei
Published: December 2013

The shear stress transfer of prestressed anchor is the key for anchor performance and engineering design. The interface bonding strength between soil and induration has a very important role in supporting capacity of the soil anchor. It is presumed that the deformation between the soil layer rod and induration is compatible after the sliding section. Based on the Mindlin solution of a force act on the interior of a semi-infinite solid, a theory solution for the shear load of anchorage section is solved by considering the part of slip characteristics of interface in the loading process. On this basis, the shear stress of anchorage section is tested from anchor pullout test on site. Contrasted with the tests result, it is proved that the theoretical analysis is consistent with the tests. Theoretically, the research of shear stress transfer will enrich and develop anchor cable theory.

Research on Applied Technology with the Characteristic of the Spatial Fresnel Diffraction Field of a Circle Aperture Illuminated by a Hyperbolic Secant Optical Pulse
Authors: Wang Huai Sheng
Published: December 2013

Based on the Fresnel diffraction theory and the principle of Fourier transformation, an equation is put forward to analyze the spatial diffraction intensity distribution of a circle aperture illuminated by a hyperbolic secant optical femtosecond pulse. The spatial diffraction intensity distributions are determined by the distance, the radius of the circle aperture, the Fresnel number, the width and the central wavelength of the hyperbolic optical pulse. Number calculation shows that when the radius of the circle aperture is definite, the spatial diffraction intensity is a function of the distance z. If the distance is definite, the spatial diffraction intensity is a function of the radius of the circle aperture. In a definite extent the spatial diffraction intensity remains approximately a constant. A constant spatial intensity distribution is good for optical imaging and laser fusion.

Authors: Ma Yong Qiang
Published: December 2013

A large number of experiments have been carried out in this study to reveal the effect of the steel fiber dosage on the mechanical properties of HPC (high performance concrete). The mechanical property includes compressive strength, elastic modulus and flexural strength. The results indicate that the addition of steel fiber increase the compressive strength, elastic modulus and flexural strength of HPC. When the steel fiber dosage is less than 2%, these mechanical property parameters are increasing gradually with the increase of steel fiber dosage, while these parameters begin to decrease when the steel fiber dosage is more than 2%. With the development of HPC, the application of steel fibers in HPC becomes more and more popular. In the actual construction of steel fiber reinforced HPC, the dosage of steel fiber should be controlled strictly in order to ensure that the steel fibers can perform their best improvement on high performance concrete.

Research on the Wear Resistance of High-Chromium White Cast Iron and Multi-Component White Cast Iron
Authors: Yen Chien Lung , Chen Fu Je , Pan Yung Ning
Published: December 2013

The pin-on-disk wear test and solid particle erosion test were used to investigate the wear resistance property of both high chromium white cast iron and multi-component white cast iron with optimal alloy compositions and heat treatment conditions. Experimental results indicate that a linear relationship between the wear lose and the testing time exists for high chromium white cast irons. Apparent scratch grooves and sheared pits appeared on the specimen surface. Subsurface observations found pit depths of some 4.5~8.0 mm. Crack propagation routes were clearly visible along the martensitic grain boundaries for alloys in the as-quenched state. Tempering treatment increases the toughness of the alloy, resulting in an increase in the resistance to crack formation. On the other hand, the multi-component white cast irons exhibited a non-linear relationship between the wear lose and the testing time. Relatively shallow scratches were found on the specimen surface, and pit depths of about 4.0 mm were observed through subsurface observations. Tempering at 570°C caused a reduction in hardness of the alloy, and therefore, the fracture mode tends to be ductile. As a result, deformation only occurred in crater regions with no clear evidence of spreading.

Existence and Stability of Periodic Planar Standing Waves in Phase-Transitional Elasticity with Strain-Gradient Effects I: General Theory
Authors: Yao Jinghua
Published: December 2013

Extending investigations of Antman &Malek-Madani, Schecter & Shearer, Slemrod, Barker & Lewicka & Zumbrun, and others, we investigate phase-transitional elasticity models with strain-gradient effect. We prove the existence of non-constant planar periodic standing waves in these models by variational methods, for deformations of arbitrary dimension and general, physical, viscosity and strain-gradient terms. Previous investigations considered one-dimensional phenomenological models with artificial viscosity/strain gradient effect, for which the existence reduces to a standard (scalar) nonlinear oscillator. For our variational analysis, we require that the mean vector of the unknowns over one period be in the elliptic region with respect to the corresponding pure inviscid elastic model. Previous such results were confined to one-dimensional deformations in models with artificial viscosity–strain-gradient coefficients.

Convergence of Variational Approximation Schemes for Elastodynamics with Polyconvex Energy
Authors: Miroshnikov Alexey , Tzavaras Athanasios E.
Published: December 2013

We consider a variational scheme developed by S. Demoulini, D. M. A. Stuart and A. E. Tzavaras [Arch. Ration. Mech. Anal. 157 (2001), 325–344] that approximates the equations of three dimensional elastodynamics with polyconvex stored energy. We establish the convergence of the time-continuous interpolates constructed in the scheme to a solution of polyconvex elastodynamics before shock formation. The proof is based on a relative entropy estimation for the time-discrete approximants in an environment of

L^p

-theory bounds, and provides an error estimate for the approximation before the formation of shocks.

\omega

-limit sets

\{\omega(x, f): x \in I\}

{\cal R}(\omega) = \{\omega(x,f): (x,f) \in I \times C(I,I)\}

, the range of

\omega

, and

{\cal R}({\cal L})= \{{\cal L}(f): f \in C(I,I)\}

, the range of

{\cal L}

. In particular,

{\cal R}(\omega)

and its complement are both dense,

{\cal R}(\omega)

is path-connected, and

{\cal R}(\omega)

is the disjoint union of a dense

G_{\delta}

set and a first category

F_{\sigma}

set. We see that

{\cal R}({\cal L})

is porous and path-connected, and its closure contains

{\cal K} = \{F \subseteq [0,1]: F \text{ is closed}\}

. Moreover, each of the sets

{\cal R}(\omega)

and

{\cal R}({\cal L})

demonstrates a self-similar structure.
Asymptotic Behavior of Inexact Infinite Products of Nonexpansive Mappings in Metric Spaces
Authors: Reich Simeon , Zaslavski Alexander J.
Published: December 2013

We study the influence of errors on the convergence of infinite products of nonexpansive mappings in metric spaces. Previously, certain convergence results were proved under the assumption that all exact orbits converge uniformly on the whole space. In the present paper, we improve upon these results by proving the convergence of inexact orbits only assuming uniform convergence of exact orbits on bounded subsets of the metric space. We also provide applications to the convex feasibility problem in Hilbert space.
A Note on the Composition of Regular Functions
Authors: Aziz Wadie , Merentes Nelson , Sánchez José Luis
Published: December 2013

In this note we give a condition on a function

h:\mathbb{R}\rightarrow\mathbb{R}

, both necessary and sufficient, under which the nonlinear composition operator

Hf = h \circ f

maps the space of all regular functions

f : [a,b] \rightarrow \mathbb{R}

into itself. Moreover, we show that in this case the operator

H

is automatically bounded in the supremum norm.
Systematic Review of the Effectiveness of Occupational Therapy–Related Interventions for People With Amyotrophic Lateral Sclerosis
Authors: Arbesman Marian , Sheard Kendra
Published: December 2013

We describe the results of a systematic review of the literature on occupational therapy–related interventions for people with amyotrophic lateral sclerosis (ALS). The review included 14 studies. We found limited to moderate evidence that people involved in multidisciplinary programs have longer survival than those in general care and limited evidence that those in multidisciplinary programs have a higher percentage of appropriate assistive devices and higher quality of life in social functioning and mental health. Limited evidence indicates that people with ALS are satisfied with the comfort and ease of use of their power wheelchairs (PWCs). In addition, limited evidence is available that PWCs allow people to have increased interaction in the community. Evidence also is limited that some assistive devices are more helpful than others. Moderate evidence indicates that a home exercise program of daily stretching and resistance exercise results in improved function. The implications for practice, education, and research are discussed.
Systematic Review of Occupational Therapy–Related Interventions for People With Multiple Sclerosis: Part 1. Activity and Participation
Authors: Yu Chih-Huang , Mathiowetz Virgil
Published: December 2013

This article is the first part of a systematic review of studies on occupational therapy–related intervention for people with multiple sclerosis (MS). The objective of this systematic review was to critically appraise and synthesize the applicable findings to address the following focused question: What is the evidence for the effectiveness of interventions within the scope of occupational therapy practice for people with multiple sclerosis? This article focuses on occupational therapy interventions aimed at activity and participation, including programs (e.g., inpatient and outpatient rehabilitation) in which an occupational therapy practitioner was one member of the team. Part 2 (Yu & Mathiowetz, 2014) focuses on interventions within the scope of occupational therapy to remediate impairment (e.g., exercise, cognition, emotional regulation).

Age-related medical conditions such as Parkinson’s disease (PD) compromise driver fitness. Results from studies are unclear on the specific driving errors that underlie passing or failing an on-road assessment. In this study, we determined the between-group differences and quantified the on-road driving errors that predicted pass or fail on-road outcomes in 101 drivers with PD (mean age = 69.38 ± 7.43) and 138 healthy control (HC) drivers (mean age = 71.76 ± 5.08). Participants with PD had minor differences in demographics and driving habits and history but made more and different driving errors than HC participants. Drivers with PD failed the on-road test to a greater extent than HC drivers (41% vs. 9%), χ2(1) = 35.54, HC N = 138, PD N = 99, p < .001. The driving errors predicting on-road pass or fail outcomes (95% confidence interval, Nagelkerke R2 =.771) were made in visual scanning, signaling, vehicle positioning, speeding (mainly underspeeding, t(61) = 7.004, p < .001, and total errors. Although it is difficult to predict on-road outcomes, this study provides a foundation for doing so.
Systematic Review of the Effectiveness of Occupational Therapy–Related Interventions for People With Parkinson’s Disease
Authors: Foster Erin R. , Bedekar Mayuri , Tickle-Degnen Linda
Published: December 2013

We describe the results of a systematic review of the literature on occupational therapy–related interventions for people with Parkinson’s disease (PD). Three broad categories of intervention emerged: (1) exercise or physical activity; (2) environmental cues, stimuli, and objects; and (3) self-management and cognitive–behavioral strategies. Moderate to strong evidence exists for task-specific benefits of targeted physical activity training on motor performance, postural stability, and balance. Low to moderate evidence indicates that more complex, multimodal activity training supports improvement in functional movement activities. The evidence is moderate that the use of external supports during functional mobility or other movement activities has positive effects on motor control. In addition, moderate evidence is available that individualized interventions focused on promoting participant wellness initiatives and personal control by means of cognitive–behavioral strategies can improve targeted areas of quality of life. The implications for practice, education, and research are discussed.
Self-Generated Strategic Behavior in an Ecological Shopping Task

Published: December 2013

OBJECTIVES. The use of cognitive strategies optimizes performance in complex everyday tasks such as shopping. This exploratory study examined the cognitive strategies people with traumatic brain injury (TBI) effectively use in an unstructured, real-world situation.

METHOD. A behavioral analysis of the self-generated strategic behaviors of 5 people with severe TBI using videotaped sessions of an ecological shopping task (Instrumental Activities of Daily Living Profile) was performed.

RESULTS. All participants used some form of cognitive strategy in an unstructured real-world shopping task, although the number, type, and degree of effectiveness of the strategies in leading to goal attainment varied. The most independent person used the largest number and a broader repertoire of self-generated strategies.

CONCLUSION. These results provide initial evidence that occupational therapists should examine the use of self-generated cognitive strategies in real-world contexts as a potential means of guiding therapy aimed at improving independence in everyday activities for people with TBI.
