An Examination Of Coordination Among Friends And Strangers From A Coordination Theory Perspective, Christopher D. Wamble

Theses

Within mobile social coordination, there is a field of study known as outeraction, the communicative processes used by people to manage future interactions. It is an important area of research because it identifies how informal interactions support complex collaboration between individuals and groups. Outeraction is primarily conducted through the interpersonal communication channels of texting, instant messaging (IM), face-to-face, and mobile phone or Skype conversations. Currently this area of research in mobile outeraction support systems is weak. It lacks a firm foundation in system building, has very few if any conceptual frameworks, and little empirical knowledge of user requirements and attitudes …

Developing A Virtual City For Emergency Preparedness Planning And Training, Jon K. Morgan

Theses

Existing techniques for emergency preparedness planning and training fail or lack the ability to convey training on a broad scale and timely fashion. Skill sets that are required for planning, mitigation, response and recovery issues are lost through information overload or failure to identify other channels in which to convey the information. In order to resolve some of the issues with currently existing methods such as tabletop training exercises (TTX), instructional video learning and full-scale exercises we can turn to virtual environments.

In a virtual environment teams can interact with their surroundings from the comfort of the office without having …

Sharing The Big Apple : A Survey Study Of People, Place And Locatability, Samer Nadim Karam

Theses

Over the past half century social trends and new technologies have weakened local social ties and thus, the fabric of civil society itself. Mobile location-aware community systems offer one path to redress these problems by enhancing community cohesion and the formation of social capital by helping people to meet each other and coordinate their actions. However, little is known about the general population's desire and attitude towards these systems.

The design space described by the People-to-People-to-Geographical-Places Framework (P3-Framework), was used to guide a survey study of the impact of 'place' on people's social information needs and their willingness to share …

A Toolkit For Xml-Based And Process-Oriented Application Integration, Volker Münch

Theses

Systems integration is hard work; different architectures with different interfaces and an innumerable amount of Legacy applications with non-standard interfaces exist. However the needs to meet changing business requirements and to implement faster and optimised procedures within an enterprise and in cooperation with other external enterprises mean that there is a continuing demand for such integration strategies and products. Integration was often an activity separate from system development and could not be accomplished without re-involving system designers and developers. Such a process is therefore inefficient and costly. This thesis proposes a process-oriented integration strategy that combines the tasks of integration …

Development And Characterization Of Techniques For Neuro-Imaging Registration, Carlo Ciulla

Theses

Three automated techniques were developed for the alignment of Neuro-Images acquired during distinct scanning periods and their performance were characterized. The techniques are based on the assumption that the human brain is a rigid body and will assume different positions during different scanning periods. One technique uses three fiducial markers, while the other two uses eigenvectors of the inertia matrix of the Neuro-Image, to compute the three angles (pitch, yaw and roll) needed to register the test Neuro-Image to the reference Neuro-Image. A rigid body transformation is computed and applied to the test Neuro-Image such that it results aligned to …

Computer Implementation Of Mason's Rule And Software Development Of Stochastic Petri Nets, Xiaoyong Zhao

Theses

A symbolic performance analysis approach for discrete event systems can be formulated based on the integration of Petri nets and Moment Generating Function concepts [1-3]. The key steps in the method include modeling a system with arbitrary stochastic Petri nets (ASPN), generation of state machine Petri nets with transfer functions, derivation of equivalent transfer functions, and symbolic derivation of transfer functions to obtain the performance measures. Since Mason's rule can be used to effectively derive the closed-form transfer function, its computer implementation plays a very important role in automating the above procedure. This thesis develops the computer implementation of Mason's …

Performance Analysis Of Queueing Systems With Synchronous Server, Wonmu Hur

Theses

The performance measures are derived for a queueing system which is characterized by its synchronous server operations. This property is the one which normal queueing systems lack. A system of this nature contains a single common server to which multiple number of buffers are connected in parallel, where the server operates only when all system buffers are occupied.

In this thesis, the analysis is carried out focusing on the simplest system involving only two buffers. Throughout the analysis, a symmetricity of the system is assumed (i.e., system is symmetrical in terms of arriving customer statistics.). Also assumed are the Poisson …

Character Recognition Using String Matching, Xiaozhi Ye

Theses

To handle noisy and distorted pattern is the use of similarity or distance measures. A similarity or distance measure can be defined between a representation of an unknown pattern and a representation of a prototype pattern. Recognition of the unknown pattern can be carried out on the basis of the maximum-similarity or minimum distance criterion (Bunke 1990) This approach is proposed to recognize the noisy or distorted character image. In this work, a directly string representation of the pattern ( prototype as well as unknown input) using the histogram method, a decision procedure for classification is the well known Levenshtein …

Design And Implementation Of Two Text Recognition Algorithms, Madhumathi Yendamuri

Theses

This report presents two algorithms for text recognition. One is a neural-based orthogonal vector with pseudo-inverse approach for pattern recognition. A method to generate N orthogonal vectors for an N-neuron network is also presented. This approach converges the input to the corresponding orthogonal vector representing the prototype vector. This approach can restore an image to the original image and thus has error recovery capacility. Also, the concept of sub-networking is applied to this approach to enhance the memory capacity of the neural network. This concept drastically increases the memory capacity of the network and also causes a reduction of the …

New algorithms using this new mid-crack code for image representation, restoration, and skeletonization are developed. The efficiency and accuracy can be increased obviously.

Firstly, the conversion of a binary image with multiple regions into the mid-crack codes is presented. A fast on-line implementation can be achieved using tables look-up. The input binary image may contain several object regions and their mid-crack codes can be extracted at the same time in a single-pass row-by-row …

Decomposition Of Geometric-Shaped Structuring Elements And Optimization On Euclidean Distance Transformation Using Morphology, Hong Wu

Theses

Mathematical morphology which is based on geometric shape, provides an approach to the processing and analysis of digital images. Several widely-used geometric-shaped structuring elements can be used to explore the shape characteristics of an object. In first chapter, we present a unified technique to simplify the decomposition of various types of big geometric-shaped structuring elements into dilations of smaller structuring components by the use of a mathematical transformation. Hence, the desired morphological erosion and dilation are equivalent to a simple inverse transformation over the result of operations on the transformed decomposable structuring elements. We also present a strategy to decompose …

Dynamic Machine Scheduling, Expansion, And Control Of A Generic Workcell, Peter A. Murray

Theses

Factory automation has come a long way since the invention of the automatic flour mill. A workcell is a group of machines (robots) working together to produce a product.
