Abstract/Description
This thesis is concerned with an outline survey on the modern aspects of asynchronous transmission mode (ATM) telecommunication; also considered are certain specific issues such as the performance characteristics of ATM-based telecommunication networks under fluctuating workloads. Estimation of the stochasticity of the jitter associated with the cell-delay arising out of buffering within the network as well as due to signal-to-noise considerations which induce bit-errors and eventually lead...
Show moreThis thesis is concerned with an outline survey on the modern aspects of asynchronous transmission mode (ATM) telecommunication; also considered are certain specific issues such as the performance characteristics of ATM-based telecommunication networks under fluctuating workloads. Estimation of the stochasticity of the jitter associated with the cell-delay arising out of buffering within the network as well as due to signal-to-noise considerations which induce bit-errors and eventually lead to cell-losses manifesting as delay(s) in the cells being transmitted, is also addressed as a part of this thesis efforts. Relevant theoretical models are proposed, algorithms are developed and simulations are done on the above considerations. Based on these efforts, inferential conclusions are drawn and discussed. Scope for future research and developments towards engineering design of softwares suitable for practical applications by ATM networking planners and traffic forecasters is indicated. Merits and shortcomings of the models are proposed and algorithmic approaches pursued in the present study are also specified with relevant discussions.

An integrated framework for home healthcare delivery.
Creator
Conaster, Mark., College of Engineering and Computer Science, Department of Computer and Electrical Engineering and Computer Science
Abstract/Description
With the increasing demands of rising medical costs in combination with a boom in elderly patients in need of quality patient care medical practices are being stressed. Patient to nurse ratios are increasing and government spending in the medical domain is at an all-time high threatening the futures of government medical programs such as Medicare and Medicaid. In this thesis we propose a framework for the monitoring of a patient's vital statistics in a home-based setting using a mobile smart...
Show moreWith the increasing demands of rising medical costs in combination with a boom in elderly patients in need of quality patient care medical practices are being stressed. Patient to nurse ratios are increasing and government spending in the medical domain is at an all-time high threatening the futures of government medical programs such as Medicare and Medicaid. In this thesis we propose a framework for the monitoring of a patient's vital statistics in a home-based setting using a mobile smart device. We believe that in taking advantage of the wireless sensor technology which is readily available today we can provide a solution that is both economically and socially viable offering a solid quality of healthcare in a comfortable and familiar environment. Our framework exposes both 802.11 and Bluetooth wireless protocol transmitting medical sensor devices using an Android platform device as a monitoring hub.

Comparing the use of second language communication strategies in oral interaction and synchronous computer-mediated communication
Title
Comparing the use of second language communication strategies in oral interaction and synchronous computer-mediated communication.
Creator
Knierim, Markus., Florida Atlantic University, DuBravac, Stayc
Abstract/Description
This study investigates whether synchronous computer-mediated communication (CMC) has the potential to foster second language learners' strategic competence (as a component of communicative competence). For this purpose, the use of communication strategies (CSs) by 15 fourth-semester students of German during four computer-mediated and four oral "jigsaw" tasks is compared. The students used more CSs in oral interaction, which is attributed to a lesser degree of utterance planning in oral...
Show moreThis study investigates whether synchronous computer-mediated communication (CMC) has the potential to foster second language learners' strategic competence (as a component of communicative competence). For this purpose, the use of communication strategies (CSs) by 15 fourth-semester students of German during four computer-mediated and four oral "jigsaw" tasks is compared. The students used more CSs in oral interaction, which is attributed to a lesser degree of utterance planning in oral interaction and stronger time constraints in synchronous CMC. However, this quantitative difference is due to only five students' use of significantly more CSs in oral interaction. The distribution of the various CS types was similar in both communication modes; only code-switching occurred much more frequently in synchronous CMC, which is attributed to stronger time constraints in this medium and less monitoring by the instructor. Hence, synchronous CMC is not superior to oral interaction as far as promoting CS use is concerned.

TELEHEALTH UTILIZATION IN MENTAL HEALTH: THE UNEXPECTED CATALYST.
Creator
Perrys, John, Feyereisen, Scott, Florida Atlantic University, Department of Management Programs, College of Business
Abstract/Description
This quantitative research study explored the impact of the COVID-19 pandemic on the utilization of telehealth in mental health services, focusing on the Veterans Health Administration (VHA) of the U.S. Department of Veterans Affairs. The study assessed changes in appointment types across location, modality, gender, age, race, and rurality. Drawing on the Technology Acceptance Model (TAM) and introducing a COVID-19 moderation factor, the study investigates the adoption of telehealth...
Show moreThis quantitative research study explored the impact of the COVID-19 pandemic on the utilization of telehealth in mental health services, focusing on the Veterans Health Administration (VHA) of the U.S. Department of Veterans Affairs. The study assessed changes in appointment types across location, modality, gender, age, race, and rurality. Drawing on the Technology Acceptance Model (TAM) and introducing a COVID-19 moderation factor, the study investigates the adoption of telehealth technology and its effects on traditionally underserved groups. The research method involved a quantitative analysis of de-identified patient appointment data from FY 2017 to FY 2022, encompassing 66 million appointments. Empirical research was assessed for any impact of the coronavirus disease 2019 (COVID-19) pandemic on the proliferation of the telehealth modality in mental health. The study incorporated statistical analyses, including time series regression, to test the hypothesis that telehealth positively influenced mental health service delivery, with the COVID-19 pandemic as a moderating factor. Descriptive statistics were used to present the mean and standard deviation scores for the independent and dependent variables. Frequency statistics were used to describe the independent variables for the study further. Three regression models were used to answer the hypotheses. Comprehensive results were presented, showcasing the impact of the pandemic on telehealth adoption, and behavioral intentions. Specifically, the COVID-19 pandemic has fundamentally altered the landscape of doctoral healthcare provider visits, generally decreased in-person visits while substantially increased video and phone visits. The findings highlighted sizable shifts in healthcare dynamics, emphasizing the influence of demographic factors on visit types and the complex interplay with COVID-19. This study contributed valuable insights into the transformative role of telehealth in mental health care, especially during global health crises like the COVID-19 pandemic.

We proposed an IDR for oncology applications which can handle large datasets and which can be used on both the intranet and the Internet. It is designed to provide one or multiple medical institutions on a global scale a common platform for patient care and consultation. The proposed application consists of two key models, Body Surface Area model and Search model, which are described in detail and their results are discussed. We have implemented the proposed IDR for oncology application using ColdFusion MX. Existing research in this area have been studied and compared. Framework of the proposed IDR, structure, front-end user interface and back-end database schema of the proposed oncology application are explained in this thesis.

The basic electromagnetic properties of human tissues are investigated at 403 .5 MHz. Then, the radiation characteristics of submerged wire antenna are evaluated in order to approximate the effects of multilayered media on a PIFA's performance. The PIFA is assessed using Ansoft's Finite Element Method based electromagnetic evaluation software, HFSS v.l 0. The electrical parameters of the antenna in relation to the surrounding environment, notably air, silicone capsule, and a three-layered bio-media, are presented. The analysis shows that the resonant frequency as well as the electrical performance of the design is significantly affected by the physical dimensions and the relative permittivity of the dielectric materials covering the antenna.
