A Location-Aware Architecture Supporting Intelligent Real-Time Mobile Applications, Sean J. Barbeau
A Location-Aware Architecture Supporting Intelligent Real-Time Mobile Applications, Sean J. Barbeau
USF Tampa Graduate Theses and Dissertations
This dissertation presents LAISYC, a modular location-aware architecture for intelligent real-time mobile applications that is fully-implementable by third party mobile app developers and supports high-precision and high-accuracy positioning systems such as GPS. LAISYC significantly improves device battery life, provides location data authenticity, ensures security of location data, and significantly reduces the amount of data transferred between the phone and server. The design, implementation, and evaluation of LAISYC using real mobile phones include the following modules: the GPS Auto-Sleep module saves battery energy when using GPS, maintaining acceptable movement tracking (approximately 89% accuracy) with an approximate average doubling of battery life. …
Algorithms For Visual Maritime Surveillance With Rapidly Moving Camera, Sergiy Fefilatyev
Algorithms For Visual Maritime Surveillance With Rapidly Moving Camera, Sergiy Fefilatyev
USF Tampa Graduate Theses and Dissertations
Visual surveillance in the maritime domain has been explored for more than a decade. Although it has produced a number of working systems and resulted in a mature technology, surveillance has been restricted to the port facilities or areas close to the coastline assuming a fixed-camera scenario. This dissertation presents several contributions in the domain of maritime surveillance. First, a novel algorithm for open-sea visual maritime surveillance is introduced. We explore a challenging situation with a camera mounted on a buoy or other floating platform. The developed algorithm detects, localizes, and tracks ships in the field of view of the …
Overcoming Limitations Of Serial Audio Search, Isabela Cordeiro Ribeiro Moura Hidalgo
Overcoming Limitations Of Serial Audio Search, Isabela Cordeiro Ribeiro Moura Hidalgo
USF Tampa Graduate Theses and Dissertations
The typical approach for finding audio recordings, such as music and sound effects, in a database is to enter some textual information into a search field. The results appear summarized in a list of textual descriptions of the audio files along with a function for playing back the recordings. Exploring such a list sequentially is a time-consuming and tedious way to search for sounds. This research evaluates whether searching for audio information can become more effective with a user interface capable of presenting multiple audio streams simultaneously.
A prototype audio player was developed with a user interface suitable for both …
Design Methodologies For Reversible Logic Based Barrel Shifters, Saurabh Kotiyal
Design Methodologies For Reversible Logic Based Barrel Shifters, Saurabh Kotiyal
USF Tampa Graduate Theses and Dissertations
The reversible logic has the promising applications in emerging computing paradigm
such as quantum computing, quantum dot cellular automata, optical computing, etc. In
reversible logic gates there is a unique one-to-one mapping between the inputs and outputs.
To generate an useful gate function the reversible gates require some constant ancillary
inputs called ancilla inputs. Also to maintain the reversibility of the circuits some additional
unused outputs are required that are referred as the garbage outputs. The number of
ancilla inputs, number of garbage outputs and quantum cost plays an important role in
the evaluation of reversible circuits. Thus minimizing these …
The Creation Of A Robotics Based Human Upper Body Model For Predictive Simulation Of Prostheses Performance, Derek James Lura
The Creation Of A Robotics Based Human Upper Body Model For Predictive Simulation Of Prostheses Performance, Derek James Lura
USF Tampa Graduate Theses and Dissertations
This work focuses on the use of 3D motion capture data to create and optimize a robotic human body model (RHBM) to predict the inverse kinematics of the upper body. The RHBM is a 25 degrees of freedom (DoFs) upper body model with subject specific kinematic parameters. The model was developed to predict the inverse kinematics of the upper body in the simulation of a virtual person, including persons with functional limitations such as a transradial or transhumeral amputation. Motion data were collected from 14 subjects: 10 non-amputees control subjects, 1 person with a transradial amputation, and 3 persons with …
Design Of A Reversible Alu Based On Novel Reversible Logic Structures, Matthew Arthur Morrison
Design Of A Reversible Alu Based On Novel Reversible Logic Structures, Matthew Arthur Morrison
USF Tampa Graduate Theses and Dissertations
Programmable reversible logic is emerging as a prospective logic design style for implementation in modern nanotechnology and quantum computing with minimal impact on circuit heat generation. Recent advances in reversible logic using and quantum computer algorithms allow for improved computer architecture and arithmetic logic unit designs. In this paper, a 2*2 Swap gate which is a reduced implementation in terms of quantum cost and delay to the previous Swap gate is presented. Next, a novel 3*3 programmable UPG gate capable of calculating the fundamental logic calculations is presented and verified, and its advantages over the Toffoli and Peres gates are …
Basal Graph Structures For Geometry Based Organization Of Wide-Baseline Image Collections, Aveek Shankar Brahmachari
Basal Graph Structures For Geometry Based Organization Of Wide-Baseline Image Collections, Aveek Shankar Brahmachari
USF Tampa Graduate Theses and Dissertations
We propose algorithms for organization of images in wide-area sparse-view datasets. In such datasets, if the images overlap in scene content, they are related by wide-baseline geometric transformations. The challenge is to identify these relations even if the images sparingly overlap in their content. The images in a dataset are then grouped into sets of related images with the relations captured in each set as a basal (minimal and foundational) graph structures. Images form the vertices in the graph structure and the edges define the geometric relations between the images. We use these basal graphs for geometric walkthroughs and detection …
