A Comparison Of Web Development Technologies: Webobjects Vs. Asp.Net, Adnan Al-Ghourabi Jan 2006

A Comparison Of Web Development Technologies: Webobjects Vs. Asp.Net, Adnan Al-Ghourabi

Theses

There are at least two competing technologies for Web applications development: ASP.NET by Microsoft and WebObjects by Apple. The IBuySpy application, a web portal that has been developed by the ASP.NET team at Microsoft using the .NET framework, illustrates the best practices for developing ASP.NET applications, in terms of modular design, caching, user authentication and authorization, and state management. In this project, a similar application was developed in WebObjects so that both technologies can be compared in terms of system architecture, frameworks, reusability, development environment and tools, security, and implementation.

Tuple Board: A New Distributed Computing Paradigm For Mobile Ad Hoc Networks, Chaithanya Bondada Jan 2006

Tuple Board: A New Distributed Computing Paradigm For Mobile Ad Hoc Networks, Chaithanya Bondada

Theses

In this project, we introduce a new distributed computing paradigm called "tuple board" which is based on the tuple space abstraction originated by Gelernter and the blackboard architecture popular in distributed artificial intelligence. Most prominent implementations of tuple space systems including JavaSpaces and T-Spaces follow a centralized architecture where the space itself resides on a server, akin to a database server. Recently, researchers have attempted to develop decentralized architectures for tuple space systems. Some work includes LIME and PeerSpaces. In our opinion, the traditional implementation of tuple spaces is not well suited for ad hoc networks where devices frequently lose …

Genetic Music, Ryan Becker Jan 2006

Genetic Music, Ryan Becker

Theses

Algorithmic music composition has long been an active area of research in computer science, but the need for a human element only recently began to be more widely acknowledged. Interactive Evolutionary Computing (IEC), made popular by Karl Sims, effectively solves many high dimension problems, like music composition, involving creative and subjective elements. This work applies several Genetic Algorithm (GA) and Genetic Programming (GP) approaches, inspired by Karl Sims, to algorithmic music composition. The implementation of these IEC algorithms is described and their effectiveness compared.

Web-Based 3-D Theatre Seating Charts And Ticket Reservation Application, Patrick Henstebeck Jan 2006

Web-Based 3-D Theatre Seating Charts And Ticket Reservation Application, Patrick Henstebeck

Theses

Seating charts for theatres and stadia have always been an important part of buying tickets to a staged event, despite offering little information about the view from any particular seat. While the internet has increased the potential to provide this information, most official arena websites and online ticket brokers still only provide the standard two-dimensional diagram whose detail is limited to the approximate location of each section and which offers no guidance as to the height or slope of the section, nor any warning of any obstructing objects that would depreciate a seat s true value. The few three-dimensional models …

Group Key Agreement Protocols With Implicit Key Authentication, Jisoo Kim Jan 2006

Group Key Agreement Protocols With Implicit Key Authentication, Jisoo Kim

Theses

There have been numerous studies performed on secure group communication over unsecured channels such as the Internet and ad-hoc network. Most of the results are focused on cryptographic methods to share secret keys within the group. In the real world, however, we cannot establish an application for group communication without considering authentication of each peer (group member) since the adversary could digitally disguise itself and intrude into the key sharing process without valid membership. Therefore, authentication is an inevitable component for any secure communication protocols as well as peer group communication. In the classical design of group key protocols, each …

Electronic Voting System For Rit Student Government Elections, Sungho Maeung Jan 2006

Electronic Voting System For Rit Student Government Elections, Sungho Maeung

Theses

Recent studies argue that traditional voting systems do not encourage increased voter participation due to constraints in time, location, accuracy, and, accessibility. To ensure the rights of a democratic society and to enhance and secure the voting rights of citizens by surpassing all the limitations of the traditional voting system, the development of an electronic voting system is an attractive solution. Research on secure electronic voting systems has been conducted for at least the past two decades. We propose to develop an electronic voting system, called the Rochester Institute of Technology Student Government Election System (SGEES) based on Damgard et …

N-Body Visualizations, William Mclaughlin

Theses

In the age of technology and information, data calculations and visualizations are key to the communication and understanding of the world in which we live. It is sometimes difficult to display data in a way to make it clear and understanding, or is difficult to calculate the data to be displayed. The N-body problem has elements of both. The N-body problem is a set of N particles representing stars that move in response to the gravitational force generated by the N-1 other particles. There have been many attacks to this problem. The GRAPEcluster Project of RIT has developed software and …

M2mimud, Robert Whitcomb Jan 2006

M2mimud, Robert Whitcomb

Theses

M2MIMud is a simple MUD (multi-user dungeon) type game that is designed to run on an ad hoc network of devices without the presence of any central server. It runs over Many-to-Many Invocation (M2MI), a distributed object system API that uses broadcasts and handles, rather than IP addresses, to communicate. Most existing multi-user computer games rely on a client-server architecture with a central server storing and maintaining the state of the game. In contrast, M2MIMud runs on an ad hoc network of devices with no central server. This paper describes M2MI and its use for serverless multi-user applications, discusses the …

Integrating Database And Data Stream Systems, Rutul Mashruwala Jan 2006

Integrating Database And Data Stream Systems, Rutul Mashruwala

Theses

Traditionally, Database systems are viewed as passive data storage. Finite data sets are stored in traditional Database Systems and retrieved when needed. But applications such as sensor networks, network monitoring, retail transactions, and others, produce infinite data sets. A new system is under research and development, known as Data Stream Management System (DSMS), to deal with the infinite data sets. In DSMS, Data stream is a continuous source of sequential data. In Object-Oriented languages, like C/C++ and Java, the concept of stream does exist. The stream is viewed as a channel to which data is being inserted at one end …

Ad Hoc File System, Swarup Datta Jan 2006

Ad Hoc File System, Swarup Datta

Theses

Ad hoc File System (AFS) is middleware for peers wishing to share and access data in ad hoc fashion. AFS permits processes to export local files and import files shared by other processes. Communication between hosts is facilitated by the M2MI Framework, a novel paradigm for building collaborative systems. The API provided by AFS allows for data to be exported to the middleware, which become accessible to hosts running AFS. Interested peers can import exported data to their local system, allowing uniform access to local and remote files. Peers can also unexport and unimport data undoing effects of export and …

Efficient Encryption On Limited Devices, Roderic Campbell Jan 2006

Efficient Encryption On Limited Devices, Roderic Campbell

Theses

Encryption algorithms have been used since the dawn of time to ensure secure communication over insecure communication channels. Once a secret encryption key is established and as long as the key remains secret, two parties can communicate freely over open channels. The question of how to obtain such a secret key is a large dilemma. Many methods of obtaining such keys have been tried from the most basic form of a one-on-one encounter to more advanced techniques like Diffie-Hellman. This paper compares three versions of the Diffie-Hellman key exchange protocol -- using arithmetic in the field of integers modulo a …

Hf-Dsr: Dynamic Source Routing For High Frequency Radio Networks, Michael Stringer Jan 2006

Hf-Dsr: Dynamic Source Routing For High Frequency Radio Networks, Michael Stringer

Theses

HF-DSR is an ad hoc routing protocol designed to operate efficiently over high frequency (HF) radio networks. Ad hoc routing protocols allow networks to provide dynamic routing between endpoints. In contrast, static routing schemes require networks to be configured with potential routes in advance. As such, ad hoc routing mechanisms can compensate for unanticipated factors such as radio frequency (RF) interference or node mobility. HF-DSR is largely based on Dynamic Source Routing (DSR), a level 3 ad hoc networking protocol that emits network control information on demand. HF-DSR incorporates portions of DSR which minimize the quantity of control information transmitted. …

Routing In Anhinga, Aakash Chauhan Jan 2006

Routing In Anhinga, Aakash Chauhan

Theses

Anhinga project with Many-to-Many Protocol (M2MP) takes fundamentally different approach to resolve dynamic network topology in ad hoc networks. Instead of trying host-address based networking and routing to make work in ad hoc network environment, M2MP removes device address and groups. All messages goes to all devices within proximal area and each device decides whether and how to process the message based on message s content. [1] This project expands on this infrastructure by delivering these messages beyond sender device s broadcast range. The project implements Dynamic Source Routing (DSR) protocol based controlled flooding techniques. It also provides functionality for …

Adjusting The Margins: Building Bridges Between Deaf And Hearing Cultures Through Performance Arts, Luane Davis Haggerty Jan 2006

Adjusting The Margins: Building Bridges Between Deaf And Hearing Cultures Through Performance Arts, Luane Davis Haggerty

Theses

This study addresses a gap in scholarship on leadership styles in the Deaf community. There is an invisible style of leadership differing from the mainstream culture that has not been previously addressed in the literature at any depth. My study was composed of three interlocking parts in a sequence that constitutes the practice of anthropology: fieldwork, analysis, and presentation. The foundation for my fieldwork was an “archeology of the structure of the perceived world” (Merleau-Ponty), using the holding environment of the rehearsal process and the structural process of an acting technique called Del-Sign. Del- Sign is a fusion acting style …

Policing Performance Management Systems: Identifying Key Design Elements Within A `New' Public Management Context, John Gillespie Jan 2006

Policing Performance Management Systems: Identifying Key Design Elements Within A `New' Public Management Context, John Gillespie

Theses: Doctorates and Masters

The new public management (NPM) philosophy and move towards a governance approach places emphasis on the accountability of individuals, supervisors and managers relative to practice, processes and designated outcome - conformance and performance. A dichotomy is highlighted working within the NPM environment where managers need to practice creative and innovative freedoms, and at the same time to exercise constraint and compliance within a regulated and permission seeking framework. This situation can create inertia in respect to performance reforms within the public service. Police Services in Australia, and in particular the Western Australia Police (WAPOL) have made some inroads into providing …

Where Are The Active Citizens Of Tomorrow? We Need Them Now..., Margaret E. Piasecka Jan 2006

Where Are The Active Citizens Of Tomorrow? We Need Them Now..., Margaret E. Piasecka

Theses: Doctorates and Masters

In 1997, Hindess labelled the gap between governments and citizens the democratic deficit. This gap, or deficit, has arisen over a long time period as a result of public scandals, perceptions of poor performance and poor economies. Local governments around the world are now attempting to regain community respect and support - the unstated mandate for governance - and seeking to implement government policies relating to concepts variously described as community engagement, capacity building, active citizenship or public/citizen participation. This thesis has identified a methodology for finding people who are motivated to act in the public interest in one local …

Expanding The Protection Of Geographical Indications Of Origin Under Trips: Old Debate Or New Opportunity, Irene Calboli Jan 2006

Expanding The Protection Of Geographical Indications Of Origin Under Trips: Old Debate Or New Opportunity, Irene Calboli

Research Collection Yong Pung How School Of Law

Geographical indications of origin (GIs), their definition, and rationale for protection have historically been the subjects of heated debates in the international community. Fierce defenders of GIs protection, European countries have traditionally advocated that GIs should not be used by unrelated parties because GIs identify the unique qualities, characteristics, and reputation of the products to which they are affixed. To this claim, the United States and other "new world" countries have generally responded by pointing out that many GIs are generic terms on their soil, and, thus, consumers could not be confused as to the origin of the products identified …

A Case Study Investigation Of The Development And Treatment Of Alter Personalities In Dissociative Identity Disorder, Ian Brown Jan 2006

A Case Study Investigation Of The Development And Treatment Of Alter Personalities In Dissociative Identity Disorder, Ian Brown

Theses: Doctorates and Masters

Progress in the study and treatment of Dissociative Identity Disorder (DID) has been hampered by ideological debate regarding its validity. This is particularly the case when patient's suffering from DID also report ritualistic abuse. Part of the difficulty has been that past studies have not established independent checks to assess whether alters are artefacts introduced by therapeutic bias. This study addressed this issue by using independent judges to test the validity of a patient being treated for DID who claimed ritualistic abuse. The judges were 16 clinicians with an average of 21 years experience in their respective disciplines. The study …

Understanding Sustainable Tourism Development From A Complex Systems Perspective: A Case Study Of The Swan River, Western Australia, Janine R. Mcdonald Jan 2006

Understanding Sustainable Tourism Development From A Complex Systems Perspective: A Case Study Of The Swan River, Western Australia, Janine R. Mcdonald

Theses: Doctorates and Masters

Tourism does not operate in a predictable and mechanistic environment and is influenced by unpredictable circumstances. Influences include underlying values and perceptions keeping the system unpredictable and dynamic. Tourism that utilises natural resources is exposed to the additional unpredictability of natural changes and activities and/or decisions of other stakeholders. Tourism research generally adopts reductionist approaches and has not effectively understood tourism as a stakeholder within a complex system of stakeholders. Reductionist approaches have led to interpretations of sustainable tourism development being highly focused and sector specific limiting understanding of the complex systems in which tourism operates and resulting in narrow …
