Design Of A Highly Portable Data Logging Embedded System For Naturalistic Motorcycle Study, Noureddine Elmehraz

USF Tampa Graduate Theses and Dissertations

According to Motorcycle Industrial Council (MIC), in USA the number of owned

motorcycle increased during last few years and most likely will keep increasing. However, the

number of the deadly crash accidents associated with motorcycles is on the rise. Although MIC

doesn't explain why the accident rate has increased, the unprotected motorcyclist gear can be one

of the reasons. The most recent National Highway Traffic Safety Administration (NHTSA)

annual report stated that its data analyses are based on their experiences and the best judgment is

not based on solid scientific experiment [3]. Thus, building a framework for the data acquisition …

Human Intention Recognition Based Assisted Telerobotic Grasping Of Objects In An Unstructured Environment, Karan Hariharan Khokar

USF Tampa Graduate Theses and Dissertations

In this dissertation work, a methodology is proposed to enable a robot to identify an object to be grasped and its intended grasp configuration while a human is teleoperating a robot towards the desired object. Based on the detected object and grasp configuration, the human is assisted in the teleoperation task. The environment is unstructured and consists of a number of objects, each with various possible grasp configurations. The identification of the object and the grasp configuration is carried out in real time, by recognizing the intention of the human motion. Simultaneously, the human user is assisted to preshape over …

The Effect Overall Density Plays On Performance And Preference In A Windowed Environment, Lucas M. Downard

UNF Graduate Theses and Dissertations

This thesis consists of fundamental research into the effect that a display’s overall density has on a user’s performance and preference while performing simple tasks using a window-styled computer application specifically developed for this study. This study sought to reevaluate previous findings by exploring their application in the more current, present-day environment. In this research, overall density was considered to be a measure of a screen’s complexity and was examined at three different levels. Users performed a series of tasks using only one of three available screens with different density levels. The same tasks were performed by all users to …

Performance Evaluation And Comparison Of Distributed Messaging Using Message Oriented Middleware, Naveen Mupparaju

UNF Graduate Theses and Dissertations

Message Oriented Middleware (MOM) is an enabling technology for modern event- driven applications that are typically based on publish/subscribe communication [Eugster03]. Enterprises typically contain hundreds of applications operating in environments with diverse databases and operating systems. Integration of these applications is required to coordinate the business process. Unfortunately, this is no easy task. Enterprise Integration, according to Brosey et al. (2001), "aims to connect and combines people, processes, systems, and technologies to ensure that the right people and the right processes have the right information and the right resources at the right time"[Brosey01]. Communication between different applications can be achieved …

Energy Efficiency Performance Improvements For Ant-Based Routing Algorithm In Wireless Sensor Networks, A. M. Zungeru, Kah Phooi Seng, Li-Minn Ang, W.C. Chia

Research outputs 2013

The main problem for event gathering in wireless sensor networks (WSNs) is the restricted communication range for each node. Due to the restricted communication range and high network density, event forwarding in WSNs is very challenging and requires multihop data forwarding. Currently, the energy-efficient ant based routing (EEABR) algorithm, based on the ant colony optimization (ACO) metaheuristic, is one of the state-of-the-art energy-aware routing protocols. In this paper, we propose three improvements to the EEABR algorithm to further improve its energy efficiency. The improvements to the original EEABR are based on the following: (1) a new scheme to intelligently initialize …

Indirect Measures Of Learning Transfer Between Real And Virtual Environments, Michael J. Garrett, Mark T. Mcmahon

Research outputs 2013

This paper reports on research undertaken to determine the effectiveness of a 3D simulation environment used to train mining personnel in emergency evacuation procedures, designated the Fires in Underground Mines Evacuation Simulator (FUMES). Owing to the operational constraints of the mining facility, methods for measuring learning transfer were employed which did not require real world performance evaluation. Transfer measures that examined simulator performance relative to real world experience, fidelity assessment, and appraisal of the training value of the platform were utilised. Triangulation of results across all three measures indicated the presence of learning transfer, suggesting the viability of indirect measures …

A Method For Identifying Personalized Representations In Web Archives, Mat Kelly, Justin F. Brunelle, Michele C. Weigle, Michael L. Nelson

Computer Science Faculty Publications

Web resources are becoming increasingly personalized — two different users clicking on the same link at the same time can see content customized for each individual user. These changes result in multiple representations of a resource that cannot be canonicalized in Web archives. We identify characteristics of this problem by presenting a potential solution to generalize personalized representations in archives. We also present our proof-of-concept prototype that analyzes WARC (Web ARChive) format files, inserts metadata establishing relationships, and provides archive users the ability to navigate on the additional dimension of environment variables in a modified Wayback Machine.
