On The Relative Positioning Of Mobile Devices Through Bluetooth Analysis, Karsten Andersen, Matt Gibson

Computer Science and Engineering Senior Theses

Currently, there is no way to accurately track a mobile devices position in a given space without the use of GPS or WiFi. This means that people who are interested in understanding where they currently are in relationship to other people or landmarks and do not have access to these technologies are not able to get accurate location information. In many cases, GPS and WiFi fail to provide the accuracy required to provide useful information as well.

Our solution is a software layer that utilizes existing bluetooth hardware to create a highly accurate relative positioning system. The software layer utilizes …

These websites have begun to get away from the simple …

Conversation Station, Davis Allen, Robert Bayer

Computer Science and Engineering Senior Theses

We built a mobile application that improves speed and personalization in conversations for people struggling with verbal communication. Many people diagnosed with autism, Down syndrome, and other disorders face daily challenges involving communication due to speech impediments. Existing solutions allow users to communicate via speech cards or typing on a keyboard. However, these solutions make tradeoffs between personalization and speed, compromising what it takes to have fluid, natural) and rewarding conversations. Our solution speeds up personalized communication by applying Machine Learning principles, Artificial Intelligence, and Natural Language Processing. Our project will predict how a user will respond based on natural …

Taking Afrobarometer Data Everywhere, Christen Nguyen, Sean Thomas, Adrienne Tina

Computer Science and Engineering Senior Theses

According to statistics gathered by research group Afrobarometer, many countries in Africa lack infrastructure and basic necessities. In fact, Afrobarometer knows the specific rates of need and availability sampled across thirty-six countries but more prosperous African countries do not know these numbers. These more developed countries are in a position to help their less fortunate neighbors if only made aware of the social and economic climate in the respective areas. Our partnership with Afrobarometer will allow us to advertise these statistics through the use of a mobile application. The data will be displayed in a way that is easy for …

Scu Cube, Matt Condino, Andrew Drape, Evan Eberhardt, Cooper Mcdonnell, Brayton Mcknight, Isaac Mcquillen, James Olwell, Laura Tschudy

Interdisciplinary Design Senior Theses

Traditional forms of communication such as landlines and cell phones are unreliable during disaster scenarios. It is difficult to coordinate relief efforts in the aftermath of a disaster due to the unavailability of reliable communication methods. The SCUCube is a 3U CubeSat designed to aid disaster relief communications. The satellite has an amateur radio primary payload that can send and receive standardized data packets with compatible radios, and also has an experimental attitude control system secondary payload. The semi-passive attitude control system uses a gravity gradient boom and a reaction wheel to stabilize the orientation of the satellite. In addition, …

Auto Generation Of Xliff Translation Documents From Proprietary File Formats, Kieran O'Connor, Geraldine Gray

The ITB Journal

The handling of proprietary documents by localisation vendors is time consuming and error prone, and represents a significant challenge to localisation projects. Vendors with many customers, each with its own set of document formats, must potentially support a document format set numbering in the hundreds or thousands. This paper describes an approach to automating the extraction of translatable text from a variety of file formats. The solution is based on XLIFF, language parsers, and XML transformations.

Developing Real-Time Multimedia Conferencing Services Using Java And Sip, Gavin Byrne, Declan Barber

This paper examines Java's suitability in creating real-time multimedia communications-based applications in Next Generation Networks (NGNs). We investigate some of the current enabling technologies provided by the Java plaiform which are concerned with the rapid development of realtime communications-based products and services. In particular, we look at creating a multiparty conferencing and collaboration service using the Session Initiation Protocol (SIP) and the JAIN Framework and present an approach which models multiparty conferencing applications by separating signaling and media transfer functionality. We map our model through the design stage to an implementation in Java. This paper is based on real experiences …

Web Enabled Embedded Devices, Anthony Keane, Brian Myler

The ITB Journal

The trend in manufacturing of computerised control systems has been to miniaturise the components while increasing the functionality of the systems. This has led to the development of small inexpensive hand-held computer devices coupled with the availability of a user friendly application development language, Java and public cost-effect communication networks has given the developer a programmable web-enabled embedded device. This paper investigates the steps involved in programming the Tiny InterNet Interface platform and analyses the limitations imposed by miniaturisation on this device.

Soft, Vertical Handover Of Streamed Multimedia In A 4g Network, Ger Cunningham, Philip Perry, Liam Murphy

The ITB Journal

In this paper the soft, vertical handover of streamed multimedia in a 4G network is considered. We propose a soft handover solution in which the mobile client controls the handover. This solution requires no modifications to existing wireless networks. The second stream required for the soft handover is duplicated just above the transport layer, rather than requiring the server to play out a second stream that needs to be synchronised with the existing stream. Such a scheme is outlined, and the results are presented that show how the scheme functioned in an emulated environment.

The system modelled is a single axis positioning system driven via an armature controlled DC motor. The model consists of the main items in the system; pulse width modulated amplifier, DC motor, pulley and belt drive, and ball screw thread. Effects of inertia of parts and also frictional effects are also accoU;nted for in the models. The problems of combing different disciplines within each method are shown. Simulation results are presented …

Developing A Distributed Java-Based Speech Recognition Engine, Tony Ayers, Brian Nolan

The ITB Journal

The development of speech recognition engines has traditionally been the territory of low-level development languages such as C. Until recently Java may not have been considered a candidate language for the development of such a speech engine, due to its security restrictions which limited its sound processing features. The release of the Java Sound API as part of the Java Media Framework and the subsequent integration of the Sound API into the standard Java development kit provides the necessary sound processing tools to Java to perform speech recognition. This paper documents our development of a speech recognition engine using the …

Simplest Polynomial For Which Naive (Straightforward) Interval Computations Cannot Be Exact, Olga Kosheleva, Vladik Kreinovich, Songsak Sriboonchitta

Departmental Technical Reports (CS)

One of the main problem of interval computations is computing the range of a given function over given intervals. It is known that naive interval computations always provide an enclosure for the desired range. Sometimes -- e.g., for single use expressions -- naive interval computations compute the exact range. Sometimes, we do not get the exact range when we apply naive interval computations to the original expression, but we get the exact range if we apply naive interval computations to an equivalent reformulation of the original expression. For some other functions -- including some polynomials -- we do not get …

Towards Efficient Resource Provisioning In Hadoop, Peter P. Nghiem

Engineering Ph.D. Theses

Considering recent exponential growth in the amount of information processed in Big Data, the high energy consumed by data processing engines in datacenters has become a major issue, underlining the need for efficient resource allocation for better energy-efficient computing. This thesis proposes the Best Trade-off Point (BToP) method which provides a general approach and techniques based on an algorithm with mathematical formulas to find the best trade-off point on an elbow curve of performance vs. resources for efficient resource provisioning in Hadoop MapReduce and Apache Spark. Our novel BToP method is expected to work for any applications and systems which …

Recommending Personalized Schedules In Urban Environments, Cen Chen

Dissertations and Theses Collection

In this thesis, we are broadly interested in solving real world problems that involve decision support for coordinating agent movements in dynamic urban environments, where people are agents exhibiting different human behavior patterns and preferences. The rapid development of mobile technologies makes it easier to capture agent behavioral and preference information. Such rich agent specific information, coupled with the explosive growth of computational power, opens many opportunities that we could potentially leverage, to better guide/influence the agents in urban environments. The purpose of this thesis is to investigate how we can effectively and efficiently guide and coordinate the agents with …

How To Gauge The Accuracy Of Fuzzy Control Recommendations: A Simple Idea, Patricia Melin, Oscar Castillo, Andrzej Pownuk, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

Fuzzy control is based on approximate expert information, so its recommendations are also approximate. However, the traditional fuzzy control algorithms do not tell us how accurate are these recommendations. In contrast, for the probabilistic uncertainty, there is a natural measure of accuracy: namely, the standard deviation. In this paper, we show how to extend this idea from the probabilistic to fuzzy uncertainty and thus, to come up with a reasonable way to gauge the accuracy of fuzzy control recommendations.

Skin Tone Tracking Device (Chromaband), Ziyang Bian

Computer Engineering

It’s long been said that your skin is a window into your health and with many illnesses the first signs of trouble actually show up in your skin. So if we have this natural warning system, then why isn’t anyone able to effectively use it to predict changes in our health? The problem is that currently there is no reliable way to accurately measure the change in skin tone and how these changes may or may not change with variations in health. This project’s aim is to design and develop a device that will record the changes in a user’s …
