Download Question And Section Results Output For Inettest System, Pradeep Jagannath Rohokale

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

iNetTest is a useful tool to help instructors deliver computer-based tests, but when an instructor gives a test, they would often like to know individual question results, e.g.

• What was the average score for a question, how many got it correct and how many missed it,
• What was the most common answer chosen (for multiple choice, T/F, etc.),
• What was the score for a section?
• What was the average score for a section?
• etc.

Whenever individuals consider such data they often prefer different or multiple ways in which to analyze the data. For that reason, it was decided not to …

Effect Of Step Rate On Foot Strike Pattern And Running Economy In Novice Runners, Janae Lynn Richardson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Purpose—The objective was to examine if step rates ±5% or ±10% of a novice runner's preferred step rate (SR) is sufficient enough to shift a novice runner’s foot strike pattern (FSP) (rear-foot, mid-foot, forefoot) and whether these SR changes produce changes in the rate of submaximal oxygen consumption (VO2). Methods—Foot strike angle (FSA) was recorded using sagittal plane video images and VO2 was measured for novice runners while running on a treadmill at a constant speed during increased and decreased (±5% and ±10%) SR conditions. Foot strike angle was used to predict strike index (SI) (predicted strike index = [FSA …

Digital Labeling And Narrative Mapping In Mobile Remote Audio Signage: Verbalization Of Routes And Generation Of New Verbal Route Descriptions From Existing Route Sets, Tharun Tej Tammineni

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Independent navigation is a great challenge for people with visual impairments. In this project, we have designed and implemented an assisted navigation solution based on the ability of visually impaired travelers to interpret and contextualize verbal route descriptions. Previous studies have validated that if a route is verbally described in sufficient and appropriate manner then VI can use their orientation and mobility skills to successfully follow the route. In this project, we do not consider the issue how the VI will interpret the route descriptions, but we aim to identify and generate new verbal route descriptions from the existing route …

3-Way Test Suite Prioritization And Fault Detection: A Case Study, Arjun Roy Chaudhuri

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

GUI and web based applications are becoming universal. Functional accuracy of those applications is vital. Software defects caused by poor software testing can cost billions of dollars. Further, web application defects can be costly due to the fact that most web applications handle regular user interaction. By improving the time efficiency of software testing, many of the costs associated with defects can be saved. Web application users generate large numbers of possible test-cases and out of all those test-cases only some of them are vital for functional testing. Therefore testing correctness of these applications is expensive and time consuming and …

A Particle System For Musical Composition, Bruno Degazio

Publications and Scholarship

This paper describes the development of a software particle system for musical composition. It employs a generator as described in William Reeves’ seminal 1983 paper on the subject, but one in which the particles are musical themes rather than images or points of light. This is distinct from an audio-level particle system such as might be employed effectively in conjunction with granular synthesis, because an audio-level process has no “musical intelligence” in the traditional sense as the term is used in discussing rhythm, melody, harmony or other traditional musical qualities. The particle system uses the author’s software, The Transformation Engine …

Distortion Tolerant Source Code Using Viterbi Algorithm, Christopher Hankins

Electrical Engineering Undergraduate Honors Theses

Convolutional codes are used in digital communication systems in order to protect information from distortion and increase system reliability. One of the most efficient methods for decoding convolutional codes is based on the Viterbi Algorithm. Considering the fundamental similarities between these channel codes and source codes, it is logical to postulate that the Viterbi Algorithm may also provide a basis for the implementation of an efficient lossy source code. In this thesis, the Viterbi Algorithm is used to used to compress digital data from a symmetric Bernoulli source. The Viterbi source code is simulated and shown to produce results which …

Teaching And Assessment Of Mathematical Principles For Software Correctness Using A Reasoning Concept Inventory, Svetlana Drachova-Strang

All Dissertations

As computing becomes ubiquitous, software correctness has a fundamental role in ensuring the safety and security of the systems we build. To design and develop software correctly according to their formal contracts, CS students, the future software practitioners, need to learn a critical set of skills that are necessary and sufficient for reasoning about software correctness.
This dissertation presents a systematic approach to both introducing these reasoning skills into the curriculum, and assessing how well the students have learned them. Specifically, it introduces a comprehensive Reasoning Concept Inventory (RCI) that captures the fine details of basic reasoning skills that are …

Directed Percolation And The Abstract Tile Assembly Model, Tyler Garrett Moore

Graduate Theses and Dissertations

Self-assembly is a process by which simple components build complex structures through local interactions. Directed percolation is a statistical physical model for describing competitive spreading processes on lattices. The author describes an algorithm which can transform a tile assembly system in the abstract Tile Assembly Model into a directed percolation problem, and then shows simulations of the aTAM which support this algorithm. The author also investigates two new constructs designed for Erik Winfree's abstract Tile Assembly Model called the NULL tile and temperature 1.5. These constructs aid the translation between self-assembly and directed percolation and may assist self-assembly researchers in …

Identifying Robust Sift Features For Improved Image Alignment, Sanjay Abhinav Vemuri

Graduate Theses and Dissertations

In this thesis, we will study different ways to improve feature matching by increasing the quality and reducing the number of SIFT features. We created an algorithm to identify robust SIFT features by evaluating how invariant individual feature points are to changes in scale. This allows us to exclude poor SIFT feature points from the matching process and obtain better matching results in reduced time. We also developed techniques consider scale ratios and changes in object orientation when performing feature matching. This allows us to exclude false-positive feature matches and obtain better image alignment results.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Search is an important aspect of Artificial Intelligence. Efficiently searching for solutions to large problems is important. One way to scale search large in problems quickly is to divide the work between multiple processors. There are many ways to divide this work using abstractions. This thesis examines the previous way this has been done in the past and introduces other ways to more efficiently divide the work and search in parallel.

Demand Forecasting Using A Growth Model And Negative Binomial Regression Framework, Cally Yeru Ong, Murphy Choy, Michelle L. F. Cheong

Research Collection School Of Computing and Information Systems

In this paper, we look at demand forecasting by using a growth model and negative binomial regression framework. Using cumulative sales, we model the sales data for different wristwatch brands and relate it to their sales and growth characteristics. We apply clustering to determine the distinctive characteristics of each individual cluster. Four different growth models are applied to the clusters to find the most suitable growth model to be used. After determining the appropriate growth model to be applied, we then forecast the sales by applying the model to new products being launched in the market and continue to monitor …

We discuss ways to increase female participation as well as overall participation in the major.

Global Technical Communication And Content Management: A Study Of Multilingual Quality, Tatiana Batova

Theses and Dissertations

The field of technical communication (TC) is facing a dilemma. Content management (CM) strategies and technologies that completely reshape writing and translation practices are adopted in an increasing number of TC work groups. One driving factor in CM adoption is the promise of improving quality of multilingual technical texts, all the while reducing time/cost of technical translation and localization. Yet, CM relies on automation and privileges consistency¯an approach that is problematic in global TC with its focus on adapting texts based on the characteristics of end-users.

To better understand the interdisciplinary dilemma of multilingual quality in CM, during my dissertation …
