Implementation Of Switching Circuit Models As Vector Space Transformations, David Kebo Houngninou
Computer Science and Engineering Theses and Dissertations
Modeling of switching circuits is the foundation for many Electronic Design Automation (EDA) tasks and is commonly used at various phases of the design flow for tasks such as simulation, justification, and other analyses. State-of-the-art simulation tools are based on discrete event algorithms using switching algebraic models and are highly optimized and mature. Symbolic simulation may also be implemented using a discrete event approach, or other approaches based on extracted functional models. The common foundation of modern simulation tools is that of a switching or Boolean algebraic model that may be augmented with timing information. Justification using switching circuit models ...

One-To-Cloud One-Time Pad Data Encryption: Introducing Virtual Prototyping With Pspice, 2017 Dublin Institute of Technology
One-To-Cloud One-Time Pad Data Encryption: Introducing Virtual Prototyping With Pspice, Paul Tobin, Lee Tobin, Roberto Gandia Blanquer Dr, Michael Mckeever, Jonathan Blackledge Professor
In this paper, we examine the design and application of a one-time pad encryption system for protecting data stored in the Cloud. Personalising security using a one-time pad generator at the client-end protects data from break-ins, side-channel attacks and backdoors in public encryption algorithms. The one-time pad binary sequences were obtained from modified analogue chaos oscillators initiated by noise and encoded client data locally. Specific ``one-to-Cloud'' storage applications returned control back to the end user but without the key distribution problem normally associated with one-time pad encryption. Development of the prototype was aided by ``Virtual Prototyping'' in the latest version ...
Solid State Drive, 2017 California Polytechnic State University, San Luis Obispo
Solid State Drive, Shaun A. Steele
This project documents the design and implementation of a solid state drive (SSD). SSDs are a non-volatile memory storage device that competes with hard disk drives. SSDs rely on flash memory, a type of non-volatile memory that is electrically erased and programmed. The appeal of SSDs lies in the fact that they allow a fast, reliable, and durable memory storage device. The goal of this project is to have a working external SSD built from scratch.

Power Efficient High Temperature Asynchronous Microcontroller Design, Nathan William Kuhns
Theses and Dissertations
There is an increasing demand for dependable and efficient digital circuitry capable of operating in high temperature environments. Extreme temperatures have adverse effects on traditional silicon synchronous systems because of the changes in delay and setup and hold times caused by the variances in each device’s threshold voltage. This dissertation focuses on the design of the major functionality of an asynchronous 8051 microcontroller in Raytheon’s high temperature Silicon Carbide process, rated for operation over 300ºC. The microcontroller is designed in NULL Convention Logic, for which the traditional bus architecture used for data transfer would consume a large amount ...
On The Development Of A One-Time Pad Generator For Personalising Cloud Security, 2017 Dublin Institute of Technology
On The Development Of A One-Time Pad Generator For Personalising Cloud Security, Paul Tobin, Lee Tobin, Michael Mckeever, Jonathan Blackledge Profesor
Cloud computing security issues are being reported in newspapers, television, and on the Internet, on a daily basis. Furthermore, in 2013, Edward Snowden alleged backdoors were placed in a number of encryption systems by the National Security Agency causing confidence in public encryption to drop even further. Our solution allows the end-user to add a layer of unbreakable security by encrypting the data locally with a random number generator prior to uploading data to the Cloud. The prototype one-time pad generator is impervious to cryptanalysis because it generates unbreakable random binary sequences from chaos sources initiated from a natural noise ...
Recent Semantic Changes For The Term "Digital", 2016 University of Tromsø
Recent Semantic Changes For The Term "Digital", Tore Brattli
Proceedings from the Document Academy
The term digital originates from the Latin word for finger/counting and has for many years been used to denote discrete signals and information, as opposed to analog. Discrete representation is an important principle, not only in computers, but also for (printed) text, music scores and even our genes. Recently however, the use of the term has increased and the meaning expanded to include almost everything related to information technology, e.g. digital natives and digital addiction. This study investigates the core principles of digital representation and compares this concept with the recent usage, with a focus on Norwegian media ...

A System For Monitoring And Managing Indoor Air Quality And Environmental Conditions, 2016 Boise State University
A System For Monitoring And Managing Indoor Air Quality And Environmental Conditions, Ali Ibrahim
Boise State University Theses and Dissertations
The quality of indoor air depends on different types of pollutant sources existing in a semi-enclosed environment. The sources can be biological, chemical, or toxic pollutants. These sources can cause health issues and discomfort for occupants. One of the indicators of poor indoor air quality is Carbon Dioxide (CO2). CO2 can be used to indicate the indoor air exchange rate. The lack of air exchange means higher levels of CO2. High levels of indoor particulates can also be an indication of poor air quality. Due to the lack of fresh air, air circulation, and air filtration, the ...
