Simulation For Evaluating The Usability Of Integrated Flight Decks, Troy Ricardo Weeks
Simulation For Evaluating The Usability Of Integrated Flight Decks, Troy Ricardo Weeks
Theses and Dissertations
There is a modern revolution of pilot interface designs as technological advancements force industrial progress in general aviation (GA). Recent accident statistics and safety reports indicate that computerized flight decks in Technically Advanced Aircraft (TAA) present novel safety hazards. Little empirical data have been used to measure the usability of integrated flight decks due to the complexity and time-consuming nature of flight data assessment. The objectives of this thesis are (1) to describe the human factors issues that are induced by the design of the integrated flight deck, (2) to demonstrate the evaluative capabilities of a TAA flight simulator, and …
Correlogram Method For Comparing Bio-Sequences, Gandhali P. Samant
Correlogram Method For Comparing Bio-Sequences, Gandhali P. Samant
Theses and Dissertations
Sequence comparison is one of the most primitive operations used in bio-informatics. It is used as a basis for many other complex manipulations in the field of Computational Molecular Biology. Many methods and algorithms were developed to compare and align sequences effectively. Most of these methods use linear comparison and some standard scoring schemes to calculate the similarity between sequences. We described an alternative approach to compare sequences based on the correlogram method. This method has already been used in the past for comparing images. By using the correlogram method, a sequence is projected on a 3-D space and the …
Learning Implicit User Interest Hierarchy For Web Personalization, Hyoung-Rae Kim
Learning Implicit User Interest Hierarchy For Web Personalization, Hyoung-Rae Kim
Theses and Dissertations
Most web search engines are designed to serve all users in a general way, without considering the interests of individual users. In contrast, personalized web search engines incorporate an individual user's interests when choosing relevant web pages to return. In order to provide a more robust context for personalization, a user interest hierarchy (UIH) is presented. The UIH extracts a continuum of general to specific user interests from web pages and generates a uniquely personalized order to search results. This dissertation consists of five main parts. First, a divisive hierarchical clustering (DHC) algorithm is proposed to group words (topics) into …
Mindshare: A Collaborative Peer-To-Peer System For Small Groups, Gareth Charles Farrington
Mindshare: A Collaborative Peer-To-Peer System For Small Groups, Gareth Charles Farrington
Theses and Dissertations
We present Mindshare, a system for small group collaboration using Peer to Peer networking technology. This paper details the motivation behind its design, how it benefits users and details of its construction and operation. The solution focuses on the needs of small collaborating groups with limited computing experience and resources. Mindshare allows the group to share an unlimited number of files and visualize them in unified hierarchical file system. Mindshare synchronizes the files between users without user input. Its robust design allows files to be shared even when the owner is offline and allows users to work with files from …
Keyword Spotting Using Normalization Of Posterior Probability Confidence Measures, Rachna Vijay Vargiya
Keyword Spotting Using Normalization Of Posterior Probability Confidence Measures, Rachna Vijay Vargiya
Theses and Dissertations
Keyword spotting techniques deal with recognition of predefined vocabulary keywords from a voice stream. This research uses HMM based keyword spotting algorithms for this purpose. The three most important components of a keyword detection system are confidence measure, pruning technique and evaluation of results. We suggest that best match for a keyword would be an alignment in which all constituent states have high emission probabilities. Therefore score of even the worst subsequence must also be better than a threshold and a path can be represented by the score of its worst subsequence match. This confidence measure is called Real Fitting. …
