The impact of financial aid awards on Alabama community college student successMays, Theresa V 10 May 2024 (has links) (PDF)
Financial pressures, encompassing factors such as tuition, fees, books, and work-life balance, consistently substantially influence student success in higher education. Existing research highlights finances' significant role in a student's withdrawal decision. This study aimed to assess the impact of financial aid awards on the retention, persistence, and completion of students enrolled in two community colleges in Alabama, primarily those residing in rural or urban areas. The research focused on the retention and completion outcomes of first-time, full-time students who began their enrollment at two community colleges, UCC and RCC, in the fall of 2017 and received financial aid. Utilizing a quantitative causal-comparative research design, the study analyzed data measuring the retention, persistence, and completion of first-year students who received financial assistance compared to those who did not receive financial aid. A Chi-square test investigated the relationship between financial aid awards and student success. The analysis of the study results revealed that there was no significant difference in the relationship between the retention and completion rates of first-time, full-time students who received financial aid awards and those who did not receive financial aid.

Synchronization analysis and simulation of a standard IEEE 802.11g OFDM signalLowham, Keith D. 03 1900 (has links)
Approved for public release, distribution is unlimited / Synchronization of orthogonal frequency-division multiplexed (OFDM) signals is significantly more difficult than synchronization of a single-carrier system. The recently approved IEEE Standard 802.11g specifies a packet-based OFDM system that provides a basis for the discussion of OFDM synchronization in a packet-based environment. Algorithms that synchronize the receiver carrier demodulation frequency and phase, the data frame, the OFDM symbol timing, and the data symbol timing are discussed and analyzed in an AWGN channel. System View simulation is used to implement the frame and carrier frequency synchronization algorithms, where the performance of these algorithms is analyzed and they are shown to be useful detection algorithms for Standard 802.11g signal reception. / Lieutenant Commander, United States Navy
