Genetic Algorithm Automated Generation Of Multivariate Color Tables For Visualization Of Multimodal Medical Data Sets, Karl Baum, Maria Helguera, Andrzej Krol Jan 2006

Genetic Algorithm Automated Generation Of Multivariate Color Tables For Visualization Of Multimodal Medical Data Sets, Karl Baum, Maria Helguera, Andrzej Krol

Articles

In many applications there is a need to visualize multidimensional data sets. Using spatial relationships alone, display is limited to two or three dimensions. The use of color, in addition to spatial relationships, increases the dimensionality of the data that can be effectively visualized. Use of color is usually achieved through the application of color tables. The generation of color tables is not an easy task, and since color space is relatively large it is nearly impossible for an individual to consider all of the possible options. A genetic algorithm was developed to automate this task, generating color tables for …


Iterative Finite Element Deformable Model For Nonrigid Coregistration Of Multimodal Breast Images, Andrzej Krol, Mehmet Unlu, Alphonso Magri Jan 2006

Iterative Finite Element Deformable Model For Nonrigid Coregistration Of Multimodal Breast Images, Andrzej Krol, Mehmet Unlu, Alphonso Magri

Articles

We have developed a nonrigid registration technique applicable to breast tissue imaging. It relies on a finite element method (FEM) model and a set of fiducial skin markers (FSMs) placed on the breast surface. It can be applied for both intra- and intermodal breast image registration. The registration consists of two steps. First, location and displacements of corresponding FSM observed in both moving and target volumes are determined, and then FEM is used to distribute the FSM displacements linearly over the entire breast volume. After determining the displacements at all the mesh nodes, the moving breast volume is registered to …


Rytsi: The Rochester Institute Of Technology-Yale Tip-Tilt Speckle Imager, Reed Meyer, Elliott Horch, Zoran Ninkov Jan 2006

Rytsi: The Rochester Institute Of Technology-Yale Tip-Tilt Speckle Imager, Reed Meyer, Elliott Horch, Zoran Ninkov

Articles

We have constructed a new speckle imaging system that collects a large number of speckle patterns on the detector area of a large-format CCD. The system is called the RIT-Yale Tip-tilt Speckle Imager (RYTSI) because it uses two galvanometric scanning mirrors to tip and tilt each speckle pattern to a different location on the CCD chip. It therefore solves the bandwidth problem of using CCDs in speckle imaging in a unique way: the mirrors direct speckle patterns across the chip with millisecond accuracy, and the CCD is read out only when the chip is filled with patterns. The instrument was …


Reexamining Media Capacity Theories Using Workplace Instant Messaging, Yu-Ting Caisy Hung, Wei-Chang Kong, Ai-Ling Chua Jan 2006

Reexamining Media Capacity Theories Using Workplace Instant Messaging, Yu-Ting Caisy Hung, Wei-Chang Kong, Ai-Ling Chua

Articles

This study empirically examines the general propositions of media capacity theories using a newer and increasing popular communication medium: instant messaging. We developed hypothe ses based on the proposition that synchronous communication media would be perceived to be more effective for convergence communication and asynchronous communication media would be perceived to be more suitable for conveyance communication. These hypotheses were tested using data collected from 81 IM users in four organizations by means of survey instruments develped for this study. The results suggested that although IM was perceived to be a highly synchronous communication medium, it was not perceived to …

An Integer Programming Approach To The Construction Of Trend-Free Experimental Plans On Split-Plot Designs, Andres Carrano, Brian Thorn, Guillermo Lopez

Articles

In many experimental designs, the standard procedure involves randomization of the factor-level combination run order. There are cases, however, where it Is known that a time or position trend that can seriously compromise the results of the experiment may be present. These trends Include wear of tooling and equipment, leaming curves, change In temperatures, and so on, and the trends may show up as linear, quadratic, or even higher order trends. All previously published work has dealt with various methods of constructing trend-resistant run order plans on full and fractional factorial designs. These previous efforts have not addressed any additional …


Priority-Determined Multiclass Handoff Scheme With Guaranteed Mobile Qos In Wireless Multimedia Networks, Fei Hu, Neeraj Sharma Jan 2006

Priority-Determined Multiclass Handoff Scheme With Guaranteed Mobile Qos In Wireless Multimedia Networks, Fei Hu, Neeraj Sharma

Articles

The provision of multiclass services is gaining wide acceptance and will be more ubiquitous in future wireless and mobile systems. The crucial issue is to provide the guaranteed mobile quality of service (QoS) for arriving multiclass calls. In multimedia cellular networks, we should not only minimize the dropping rate of handoff calls, but also control the blocking rate of new calls at an acceptable level. This paper proposes a novel multiclass call-admission- control mechanism that is based on a dynamic reservation pool for handoff requests. In this paper, we propose the concept of servicing multiclass connections based on priority determination …

Innovation In Non-Profit And For-Profit Organizations: Visionary, Strategic, And Financial Considerations, Clyde Hull, Brian Lio Jan 2006

Innovation In Non-Profit And For-Profit Organizations: Visionary, Strategic, And Financial Considerations, Clyde Hull, Brian Lio

Articles

Innovation has been widely studied in the context of for-profit organizations. Less attention has been paid in business literature to innovation in non-profit organizations. This paper lays out a model for comparison and then explores the differnce between the two types of organizations. Using these data, predictions are made as to how these differences between the two types of innovative behavior of non-profit organizations and theories are proposed about the methods of innovation most suited to a non-profit organization. A theory model is presented which incorporates differences in vision, in strategic constraints, and in financial constraints.

Competing Discourses On Journalism Education, Nora French Jan 2006

Competing Discourses On Journalism Education, Nora French

Articles

This paper is concerned with the lack of an agreed framework for the curriculum for journalism education. The paper reports on research into the beliefs and values underlying the two main undergraduate degree programmes in journalism in Ireland, with the aim of gaining a better understanding of the concepts of journalism and journalism education on which the curricula were based. Critical discourse analysis was used in the research. The discrepancies found in the two concepts within and between different texts make clear that the problems within journalism education reflect the wider problems of lack of closure in the discourses of …

Effects Of Retinal Image Degradation On Pre-Attentive Visual Search (Pavs) Efficiency For Flicker, Movement And Orientation Stimuli, Peter Davison, James Loughman Jan 2006

Effects Of Retinal Image Degradation On Pre-Attentive Visual Search (Pavs) Efficiency For Flicker, Movement And Orientation Stimuli, Peter Davison, James Loughman

Articles

Background: Previous research has shown that several clinical conditions cause increased preattentive visual search (PAVS) times, implying reduced parallel search capabilities in glaucoma and DLB dementia. The purpose of the research reported here was to examine for the first time the resistance of PAVS to dioptric blur using targets differing from the background in terms of flicker, vertical displacement, and orientation. Resistance would enhance the applicability of PAVS as a screening method for glaucoma and other clinical conditions affecting performance of a substantial area of the retina. Method: Computer generated flicker, orientation and vertical displacement targets were used to assess …

Broken Windows: New Evidence From New York City And A Five-City Social Experiment, Bernard E. Harcourt, Jens Ludwig Jan 2006

Broken Windows: New Evidence From New York City And A Five-City Social Experiment, Bernard E. Harcourt, Jens Ludwig

Articles

In 1982, James Q. Wilson and George Kelling suggested in an influential article in the Atlantic Monthly that targeting minor disorder could help reduce more serious crime. More than twenty years later, the three most populous cities in the United States-New York, Chicago, and, most recently, Los Angeles-have all adopted at least some aspect of Wilson and Kelling's theory, primarily through more aggressive enforcement of minor misdemeanor laws. Remarkably little, though, is currently known about the effect of broken windows policing on crime. According to a recent National Research Council report, existing research does not provide strong support for the …
