Small fiber neuropathy (SFN) is a peripheral nerve condition causing neuropathic pain and autonomic complaints. Skin biopsy an important diagnostic tool for diagnosing SFN. SFN associated with conditions like diabetes mellitus autoimmune diseases, but in 53% of the patients, etiology remains unknown. Treating underlying first-line treatment, most patients will also need symptomatic treatment ba...

This paper presents a computational approach for simulating the motion of a single fiber suspended within a viscous fluid. We develop a Finite Element Method (FEM) for modeling the dynamics of a single rigid fiber suspended in a moving fluid. Our approach seeks solutions using the Newton-Raphson method for the fiber’s linear and angular velocities such that the net hydrodynamic forces and torqu...

In this paper, ultrasonic wave propagation in three phases (3P) of composite materials was investigated. The simulation was conducted by PZFlex analysis code, a time domain finite element program. The reflection and transmission characteristics with different shapes of middle layer between glass fiber and epoxy resin are investigated in order to understand basic ultrasonic behavior of energy di...

In this study, we evaluate the performance of a flow-based surface evolution fiber tracking algorithm by means of a physical anisotropic diffusion phantom with known connectivity. We introduce a novel speed function for surface evolution that is derived from either diffusion tensor (DT) data, high angular resolution diffusion (HARD) data, or a combined DT-HARD hybrid approach. We use the model-...

SLT on subject 1 (top) and 2 (bottom). Green line shows fiber skeleton extraction results from ACFSE and red shows fiber tractography from SLT. The active contour approach was able to generate the skeleton of cingulum. Fig. 2 (right). Results of ACFSE and SLT. From top to bottom, results are from 6 different volume data sets of subject 1 with 3 acquisitions. Green shows fiber skeleton extractio...

In this paper, we study the efficiency of applying the numerical simulation of a moving interface to the problem of defining fiber placement trajectories for composite structures. This new approach, which is based on an adaptation of the Fast Marching method, presents two advantages. Firstly, it simulates accurately the mechanism of an Automated Fiber Placement (AFP) machine by producing equidi...

The project management discipline is expanding within many engineering activities. This discipline can facilitate strivings toward successful accomplishment of an engineering project. Therefore, many academic institutes teach the “project management” program. This study presents a novel approach that educates engineering students to become successful project managers based on contextual learnin...

Ambivalence, the presence of positive and negative reactions toward an object, typically involves the subjective experience of conflict. We investigate the role that the perceived validity of each side of an ambivalent attitude plays in producing subjective ambivalence (SA). Consistent with the metacognitive model of attitudes, we demonstrated that SA is reduced when people doubt either the pos...

The functional perspective on attitudes suggests that individuals will be more persuaded by advertisements that match their individual needs or attitude functions. Although previous research provided correlational support for this functional approach, the current study aimed to provide a stronger, experimental test. A pilot study validated situational manipulations of the value-expressive and k...
