In another study, Thorn and Thorn examined the effect of induced blur on reading accuracy of television captions. Given the adverse effect of blur on letter acuity, and since reading involves recognizing letters, it is expected that reading performance will be degraded in the presence of blur.

As impressive as these contributions are, most have only included nominal validation efforts, typically limited to comparisons to traffic counts. We implemented the statistical model fitting in R http: The value of the critical print size, however, depends on the method of analyzing the reading speed vs.

Instead, we used probit analysis to analyze the data from each block of trials 40 trials per block to obtain the acuity threshold. All contributors will receive a keepsake packet, as will those who attend the conference.

Reading acuity was determined according to the standard method Mansfield et al,i. Based on the finding of Legge et al who showed that the maximum reading speed was virtually constant for a range of print sizes once blur was not the limiting factor, we predicted that maximum reading speed does not depend on blur.

This is especially so for those who wear progressive addition lenses because of the progressive changes in the lens power to allow the wearers to focus at different distances.

The protocol of this study was approved by the Institutional Review Board at the University of Houston. We invite you to experience printing history in the Amana Colonies and Grinnell, Iowa.

Bring your item to the conference and drop it off at registration. Volunteers will be available to assist with set up and break down on Thursday, and during transfer and set up on Friday and Saturday.

Limited to eleven participants in each of the five 1-hour sessions. They will receive their keepsake packet by mail after the Conference.

Critical print size refers to the smallest print size that could be read at the maximum reading speed, while reading acuity refers to the smallest print size that could be read. The purpose of this study was to quantify the effect of dioptric blur on reading performance in a group of normally sighted young adults.

Observers were young adults and their pupils were not dilated nor was their accommodation paralyzed. These rooms will be open during session breaks and over the lunch hour but can otherwise be locked. For example, uncorrected refractive errors can cause retinal blur, and because a small amount of uncorrected refractive errors may go undetected in young children, reading skills may not be able to develop properly if blur indeed adversely affects reading performance.

The role of printing in a devotional community and in a small town newspaper will be vividly experienced. In this study, we examined the effect of induced dioptric blur on reading performance in a group of 19 normally sighted young adults. Van seating is limited. Data Analyses Reading time and number of errors recorded for each sentence were converted to reading speed in words per minute wpm and were analyzed by fitting and comparing nonlinear mixed-effects models NLME: On Friday and Saturday there are 19 tables available in a cluster of three rooms at the IMU for vendors who would like to display for the duration of the conference, Trade Fair II.

The walks look at a wide range of lettering styles and materials, depending on the history of each city and neighborhood. After obtaining informed consent, we performed a screening test to ensure that it was safe to dilate the pupil of the observer.

Dioptric blur was induced using convex trial lenses, placed in a trial frame for the observers to wear for those who wore glasses to correct for their refractive errors, their own prescriptions were also incorporated in the trial frame.

Van transportation will depart regularly from the IMU. Because the effect of blur on visual performance depends on pupil size e.

In sum, to date, there exists very little data to allow a precise quantification of the effect of blur on reading performance. Funds raised support the Friends of Dard Hunter student scholarships.

Vendors who want to attend conference sessions must register for both the conference and a Trade Fair table. Testing began when the pupil was fully dilated. Visual acuity was measured using 4-orientation Landolt C stimuli. They were asked to read as fast and as accurately as possible.

This distance was used for blur levels of 2 and 3D. Written informed consent was obtained from each of the observers after the procedures of the experiment were explained, and before the commencement of data collection.

Please note, however, that in the event that we have more attendees than keepsakes those who contributed will receive their keepsakes first followed by those who registered first.

The maximum reading speed was relatively constant for a range of letter sizes 0. For all levels of dioptric blur, reading speed increased with print size up to a certain print size and then remained constant at the maximum reading speed.

The artificial pupil was placed in the rear cell of the trial frame so that it was as close to the eye as possible, and that the center of the artificial pupil was aligned with the visual axis of the testing eye for the testing distance. In many cases both the quality and quantity of these counts are disappointing, and definitive conclusions about model validity and accuracy are difficult to draw from them.

If the pupil was not fully dilated after 20 min, an additional drop of Tropicamide was instilled again.Process Validation of Urban Freight and Logistics Models Corresponding Author: Rick Donnelly, WSP.

Process Validation of Urban Freight and Logistics Models

Abstract. A number of innovative freight and commercial vehicle models have been built in recent years, ranging from quick response models to tour-based formulations based on truck survey data to agent-based microsimulation models.
