Parallel Implementation Of Aes Using Xts Mode Of Operation, Muna Shrestha

Culminating Projects in Computer Science and Information Technology

Data encryption is essential for protecting data from unauthorized access. The Advanced Encryption Standard (AES), among many encryption algorithms, is the most popular algorithm currently employed to secure static and dynamic data. There are several modes of AES operation. Each of these modes defines a unique way to perform data encryption. XTS mode is the latest mode developed to protect data stored in hard-disk-like sector-based storage devices.

A recent increase in the rate of data breaches has triggered the necessity to encrypt stored data as well. AES encryption, however, is a complex process. As it involves a lot of computations, …

Implementation Costs Of Spiking Versus Rate-Based Anns, Lacie Renee Stiffler

Theses and Dissertations

Artificial neural networks are an effective machine learning technique for a variety of data sets and domains, but exploiting the inherent parallelism in neural networks requires specialized hardware. Typically, computing the output of each neuron requires many multiplications, evaluation of a transcendental activation function, and transfer of its output to a large number of other neurons. These restrictions become more expensive when internal values are represented with increasingly higher data precision. A spiking neural network eliminates the limitations of typical rate-based neural networks by reducing neuron output and synapse weights to one-bit values, eliminating hardware multipliers, and simplifying the activation …

Community College Faculty Dispositions Towards Blended Learning, Robin A. Hill

CCE Theses and Dissertations

Community colleges are being encouraged to find and provide access to higher education by offering more flexible course delivery methods to meet the needs of their diverse student body. At the same time, these institutions must retain their quality of instruction, accountability for learning outcomes, and institutional obligations. Blended learning, where students attend class both on campus and online, is promoted as one solution for attaining such goals. Among the four-year undergraduate population, blended learning has been shown to support student success, meet diverse learning styles, and meet institutional obligations; however, research within the community college population is limited. In …

The Successful Implementation Of Electronic Health Records At Small Rural Hospitals, Daniel Richardson

Walden Dissertations and Doctoral Studies

Electronic health records (EHRs) have been in use since the 1960s. U.S. rural hospital leaders and administrators face significant pressure to implement health information technology because of the American Recovery and Reinvestment Act of 2009. However, some leaders and managers of small rural hospital lack strategies to develop and implement EHRs. The focus of this descriptive phenomenological study was to explore lived experiences of hospital leaders and administrators who have used successful strategies to implement EHRs in small rural hospitals. Diffusion of innovation theory shaped the theoretical framework of this study. Data were collected through telephone interviews conducted with participants …

Electronic Medical Records (Emr): An Empirical Testing Of Factors Contributing To Healthcare Professionals’ Resistance To Use Emr Systems, Emmanuel Patrick Bazile

CCE Theses and Dissertations

The benefits of using electronic medical records (EMRs) have been well documented; however, despite numerous financial benefits and cost reductions being offered by the federal government, some healthcare professionals have been reluctant to implement EMR systems. In fact, prior research provides evidence of failed EMR implementations due to resistance on the part of physicians, nurses, and clinical administrators. In 2010, only 25% of office-based physicians have basic EMR systems and only 10% have fully functional systems. One of the hindrances believed to be responsible for the slow implementation rates of EMR systems is resistance from healthcare professionals not truly convinced …
