The Past And The Promised Future Of Supersonic Flight, Rowan Seskin

Emerging Writers

The commercial aviation industry is extremely competitive, and constant innovation is an essential part of its success. In 1976, the Concorde raised the stakes by more than doubling the cruising speed of existing airliners. However, a handful of issues plagued the aircraft until its eventual retirement in November of 2003. Since then, no airliner has successfully taken its place, but the tides are turning. In my research, I investigated the factors that led to the Concorde's demise and examined the steps currently being taken to overcome those challenges.

Adoption Of Cybersecurity Policies By Local Governments 2020, Donald F. Norris Phd, Laura K. Mateczun Jd

Journal of Cybersecurity Education, Research and Practice

This paper should be of interest to the readers of this journal because it addresses a subject that has received little scholarly attention; namely, local government cybersecurity. The U.S. has over 90,000 units of local government, of which almost 39,000 are “general purpose” units (i.e., municipalities, counties, towns and townships). On average, these governments do not practice cybersecurity effectively (Norris, et al., 2019 and 2020). One possible reason is that they do not adopt and/or implement highly recommended cybersecurity policies. In this paper, we examine local government adoption or lack of adoption of cybersecurity policies using data from three surveys. …

Impact Of Threshold Clipping On Bit Error Rate In Ofdm-Like Systems, Felipe Hoshino, Theodore Grosch

The Kennesaw Journal of Undergraduate Research

In wireless communications, 3GPP LTE is one of the solutions to meet the greater transmission data rate demand. One issue inherent to this technology is the PAPR (Peak-to-Average Power Ratio) of OFDM (Orthogonal Frequency Division Multiplexing) modulation. This high PAPR affects of the efficiency of power amplifiers. One approach to mitigate this effect is the Crest Factor Reduction (CFR) technique. In this work we simulate the impact of Hard Limited Clipping Crest Factor Reduction technique on BER (Bit Error Rate) in OFDM based Systems. In general, the results showed CFR has more effect on higher digital modulation schemes, as expected. …

Autonomous Speed Control For Kia Optima, Andrew J. Combs, Kyle Fugatt, Kevin Mcfall

The Kennesaw Journal of Undergraduate Research

The standard method for speed control is the cruise control system built into most modern vehicles. These systems employ a PID controller which actuates the accelerator thus, in turn, maintains the desired vehicle speed. The main drawback of such a system is that typically the cruise control will only engage above 25 mph. The goal of this paper is to describe a system which we used to control vehicle speed from a stop to any desired speed using an Arduino microcontroller and a CAN BUS shield, from where autonomous features can be built upon. With this system, we were able …
