Am I Blue? Depressed Mood And The Consequences Of Self Focus For The Interpretation And Recall Of Ambiguous Words, Paula T. Hertel, L. El-Messidi Jan 2006

Am I Blue? Depressed Mood And The Consequences Of Self Focus For The Interpretation And Recall Of Ambiguous Words, Paula T. Hertel, L. El-Messidi

Psychology Faculty Research

In two experiments, dysphoric and nondysphoric students first concentrated on either self-focused or other-focused phrases and then performed an ostensibly unrelated task involving the interpretation of homographs with both personal and impersonal meanings. In Experiment 1, they constructed sentences for the homographs; dysphoric students' sentences were more emotionally negative (although not more personal) in the self-focused condition than in the other-focused condition. In Experiment 2, they freely associated to the homographs, and the percentage of personal meanings reflected by the associations revealed an effect of self versus other focus that depended on mood group. Following free associations, they attempted to …


Human Visual Perception Of Region Warping Distortions With Different Display And Scene Characteristics, Yang-Wai Chow, Ronald Pose, Matthew Regan, James Phillips Jan 2006

Human Visual Perception Of Region Warping Distortions With Different Display And Scene Characteristics, Yang-Wai Chow, Ronald Pose, Matthew Regan, James Phillips

Faculty of Engineering and Information Sciences - Papers: Part A

This paper presents human visual perception experiment results for a computer graphics rendering technique introduced in ACSC'05. In order to achieve a good immersive virtual reality experience, it is necessary to have at least 60 frames per second to ensure smooth motion. It is also necessary to have low end-to-end latency so that user interaction does not suffer from perceptible delays in images presented to the eyes. The Address Recalculation Pipeline (ARP) architecture reduces end-to-end latency in immersive Head Mounted Display (HMD) virtual reality systems. By using the ARP in conjunction with priority rendering, different sections of the scene are …


Comparison Of Channelized Hotelling And Human Observers In Determining Optimum Os-Em Reconstruction Parameters For Myocardial Spect, Karen L. Gilland, Benjamin M. W Tsui, Yujin Qi, Grant T. Gullberg Jan 2006

Comparison Of Channelized Hotelling And Human Observers In Determining Optimum Os-Em Reconstruction Parameters For Myocardial Spect, Karen L. Gilland, Benjamin M. W Tsui, Yujin Qi, Grant T. Gullberg

Faculty of Engineering and Information Sciences - Papers: Part A

The performance of the Channelized Hotelling Observer (CHO) was compared to that of human observers for determining optimum parameters for the iterative OS-EM image reconstruction method for the task of defect detection in myocardial SPECT images. The optimum parameters were those that maximized defect detectability in the SPECT images. Low noise, parallel SPECT projection data, with and without an anterior, inferior or lateral LV wall defect, were simulated using the Monte Carlo method. Poisson noise was added to generate noisy realizations. Data were reconstructed using OS-EM at 1 & 4 subsets/iteration and at 1, 3, 5, 7 & 9 iterations. …


In Vitro Cytotoxicity Of Formaldehyde And Glutaraldehyde Mixtures In Human Cells, Shahnaz Bakand, Chris Winder, Christian Khalil, Amanda Hayes Jan 2006

In Vitro Cytotoxicity Of Formaldehyde And Glutaraldehyde Mixtures In Human Cells, Shahnaz Bakand, Chris Winder, Christian Khalil, Amanda Hayes

Faculty of Social Sciences - Papers (Archive)

The cytotoxicity of formaldehyde, glutaraldehyde and their binary mixtures was determined using the MTS (tetrazolium salt; Promega) in vitro assay. Cytotoxicity endpoints were investigated in human cells including; pulmonary type II-like epithelial cell lines (A549), hepatoma cell lines (HepG2) and skin fibroblasts. In order to study the cytotoxic effects of airborne formaldehyde, standard atmospheres at concentrations below 10 ppm (12.3 mg/m3) were generated using a dynamic diffusion method. Formaldehyde was bubbled through serum free culture media and cell viability was investigated after treating cells with formaldehyde air samples. HepG2 cells were found to be more sensitive (IC50 …
