Mobile Ad Hoc Networks In Transportation Data Collection And Dissemination, Kardigue Konte
Mobile Ad Hoc Networks In Transportation Data Collection And Dissemination, Kardigue Konte
Theses and Dissertations
The field of transportation is rapidly changing with new opportunities for systems solutions and emerging technologies. The global economic impact of congestion and accidents are significant. Improved means are needed to solve them. Combined with the increasing numbers of vehicles on the road, the net economic impact is measured in the many billions of dollars. Promising methodologies explored in this thesis include the use of the Internet of Things (IoT) and Mobile Ad Hoc Networks (MANET). Interconnecting vehicles using Dedicated Short Range Communication technology (DSRC) brings many benefits. Integrating DSRC into roadway vehicles offers the promise of reducing the problems …

Implementation And Analysis Of The Iso/Iec/Ieee P21451-1 Draft Standard For A Smart Transducer Interface Common Network Services And Its Applications In The Internet Of Things, Russell Henry Albert Trafford
Theses and Dissertations
The Internet of Things (IoT) has rapidly become the paradigm for the creation and improvement of new and old Cyber Physical Systems (CPS), but how much longer can this development of IoT devices, networks, and services be sustained? The past decade has seen incredible growth in internet connected devices, with current estimates placing the number of such devices at about 20 billion in 2017, not including personal computers, smart phones, and tablets. This has created a massive market for these devices, with each company making their own applications, protocols, and services. Since these markets are competitive, there originally was no …
Emotion Recognition Using Facial Feature Extraction, Demiyan Smirnov
Emotion Recognition Using Facial Feature Extraction, Demiyan Smirnov
Theses and Dissertations
Computerized emotion recognition systems can be powerful tools to help solve problems in a wide range of fields including education, healthcare, and marketing. Existing systems use digital images or live video to track facial expressions on a person's face and deduce that person's emotional state. The research presented in this thesis explores combinations of several facial feature extraction techniques with different classifier algorithms. Namely, the feature extraction techniques used in this research were Discrete Cosine/Sine Transforms, Fast Walsh-Hadamard Transform, Principle Component Analysis, and a novel method called XPoint. Features were extracted from both global (using the entire facial image) and …
Inverted Cone Convolutional Neural Network For Deboning Mris, Oliver John Palumbo
Inverted Cone Convolutional Neural Network For Deboning Mris, Oliver John Palumbo
Theses and Dissertations
Data plenitude is the power but also the bottleneck for data-driven approaches, including neural networks. In particular, Convolutional Neural Networks (CNNs) require an abundant database of training images to achieve a desired high accuracy. Current techniques employed for boosting small datasets are data augmentation and synthetic data generation, which suffer from computational complexity and imprecision compared to original datasets. In this thesis, we intercalate prior knowledge based on the temporal relation between the images in the third dimension. Specifically, we compute the gradient of subsequent images in the dataset to remove extraneous information and highlight subtle variations between the images. …
Applying Internet Of Things Principles To Spacecraft, Brian K. Dixon
Applying Internet Of Things Principles To Spacecraft, Brian K. Dixon
Theses and Dissertations
This thesis proposes the adaptation of the IEEE 1451 Transducer Electronic Data Sheet (TEDS) for usage in spacecraft subsystems. In the 1990s, TEDS initially were developed as a standardized method to provide metadata required for the operation of a transducer by a microcontroller or data acquisition device. The metadata provides information that identifies and documents key characteristics of the transducer, thereby facilitating plug-and-play interoperability within a system and across networks. An overarching goal of this thesis is to make a case for adapting and extending the TEDS concept as a means for self-describing critical physical components of a CubeSat nanosatellite. …
