Abstract / Description
The purpose of this study was to discern the effectiveness of Cardiac Rehabilitation/ Secondary Prevention Programs (CR/ SPPs) by evaluating increased functional capacity in the form of MET (metabolic equivalent) scores post-myocardial infarction (MI) or heart attack. The Duke Activity Status Index (DASI) survey is administered as part of the Standard Operating Procedure (SOP) for participation in the Secondary Prevention Program. Criterion for the research included patients 65 and older,...
Show moreThe purpose of this study was to discern the effectiveness of Cardiac Rehabilitation/ Secondary Prevention Programs (CR/ SPPs) by evaluating increased functional capacity in the form of MET (metabolic equivalent) scores post-myocardial infarction (MI) or heart attack. The Duke Activity Status Index (DASI) survey is administered as part of the Standard Operating Procedure (SOP) for participation in the Secondary Prevention Program. Criterion for the research included patients 65 and older, with a history of one myocardial infarction, and had completed all 36 sessions of CR. The scores from 11 SPP surveys were analyzed and compared in three time increments from sessions 1-18 (initial, or"pre"), sessions 19-36 ("pan"), and sessions 1-36 ("post"). A total of 11 (n=11) surveys were collected and analyzed at The Computing and Statistical Technology Laboratory in Education (CASTLE) in the Teaching Academy on UCF Main Campus. Results from the data showed mean MET scores of 6.21 at session 1, 7.59 at session 18, and 8.15 at session 36. The mean changes over time represented in METs were 1.38 (1), .56 (18), and 1.93 (36). Percent changes over time were 27% (1), 8% (18), and 36% (36). This study showed increased functional capacity over time and will improve program design in terms of frequency and duration.

Abstract / Description
This work provides a fundamental view of the mechanisms which affect the power efficiency of communications processes along with a method for efficiency enhancement. Shannon's work is the definitive source for analyzing information capacity of a communications system but his formulation does not predict an efficiency relationship suitable for calculating the power consumption of a system, particularly for practical signals which may only approach the capacity limit.

Show moreThis work provides a fundamental view of the mechanisms which affect the power efficiency of communications processes along with a method for efficiency enhancement. Shannon's work is the definitive source for analyzing information capacity of a communications system but his formulation does not predict an efficiency relationship suitable for calculating the power consumption of a system, particularly for practical signals which may only approach the capacity limit. This work leverages Shannon's while providing additional insight through physical models which enable the calculation and improvement of efficiency for the encoding of signals. The proliferation of Mobile Communications platforms is challenging capacity of networks largely because of the ever increasing data rate at each node. This places significant power management demands on personal computing devices as well as cellular and WLAN terminals. The increased data throughput translates to shorter meantime between battery charging cycles and increased thermal footprint. Solutions are developed herein to counter this trend. Hardware was constructed to measure the efficiency of a prototypical Gaussian signal prior to efficiency enhancement. After an optimization was performed, the efficiency of the encoding apparatus increased from 3.125% to greater than 86% for a manageable investment of resources. Likewise several telecommunications standards based waveforms were also tested on the same hardware. The results reveal that the developed physical theories extrapolate in a very accurate manner to an electronics application, predicting the efficiency of single ended and differential encoding circuits before and after optimization.
