Symmetric key block ciphers, such as AES, are well known and frequently used. There are five confidentiality modes of operation that are currently recommended for use with a symmetric key block cipher algorithm: Electronic Codebook (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB), Output Feedback (OFB), and Counter (CTR). This...
Drones are being used increasingly in the transportation sector for roadside applications such as surveying, structural inspection, and traffic monitoring, which raises distraction concerns for drivers. This study examines the visual attention of a group of Oregon drivers to determine drones’ potential as distracting roadside elements. Eye tracking data was...
Species conservation depends on robust population assessment. Data on population abundance, distribution, and connectivity are critical for effective management, especially as baseline information for newly documented populations. I describe a pygmy blue whale (Balaenoptera musculus brevicauda) population in New Zealand waters with year-round presence that overlaps with industrial activities. This...
The distribution of mobile marine predators often reflects underlying dynamic ecological processes. The geographical focus of this PhD is the South Taranaki Bight (STB) of New Zealand, where wind-driven coastal upwelling generates productivity and prey to support a blue whale foraging ground. The STB is also New Zealand’s most industrial...
Student engagement has been the focus of much engineering education research, in large part due to its ties to student learning. Widely considered to be a meta-construct, student engagement is often broken down into behavioral, emotional, and cognitive components. Reasons for ongoing research on student cognitive engagement are twofold: educators...
Friends benefit both our psychological and our emotional well-being by increasing overall happiness, life satisfaction, and a positive sense of self among women. Often, however, friendships decrease in the later years. The purpose of this study is to learn more about divorced or widowed, retired women and their friendships, specifically,...
A growing number of nonmetropolitan communities have chosen to pursue
nontraditional avenues for economic development including the promotion of the
nonmetropolitan area to older adults who may choose to migrate after retirement. The
purpose of this study was to help community leaders in nonmetropolitan areas make
informed decisions if they...
Detonation combustion is of great interest for propulsion devices because of its potential to increase thermodynamic efficiency, reduce the weight of current gas turbine engines, and rapidly accelerate to high Mach numbers. Detonation engines might also have the ability to decrease harmful exhaust products from traditional propulsion methods. In order...
Unmanned aerial systems (UASs), more commonly known as drones, have recently achieved commercial success for many public and private applications. As with all emerging technologies, new safety concerns and conflicts with existing paradigms are likely to arise. Many potential applications of UASs will result in their operation near roadway infrastructure,...
State Departments of Transportation (DOTs) are the primary owners of roadway infrastructure in the United States. Many of the employees of state DOTs work on roadway work sites, putting them at disproportionately higher risks of injury or fatality. A review of the literature determined that a combination of policies, standards,...
