LEYBA, JASON. Higher Order Primitives for the Reconstruction of Coarsely Sampled Imagery. (Under the direction of Dr. Benjamin Watson). While computer-processing power continues to grow at rates predicted by Moore’s Law, display technologies have lingered and grown at a much slower pace. The ability to display interactive printer-resolution images will not be achievable for several years at the...

We propose a novel variational approach to automatically soft-segment medical images into a fixed number of classes. Our method combines fuzzy classification and active contours in a single variational framework. This approach allows the use of tools from both deformable geometry and clustering in a well-defined setting and provides a useful, unsupervised segmentation technique. The model was t...

The described Fuzzy Controller was implemented in a test car and performed quite well in various driving situations. The behavior of the active accelerator pedal felt very " human like " and fulfilled the requirements described in section 3. The part of a test drive with the Fuzzy ACC presented in Figure 6 shows that the accuracy of the acceleration control was high enough to meet the intention...

In the framework of fuzzy algebras with fuzzy equalities and acomplete lattice as a structure of membership values, we investigate fuzzyequational classes. They consist of special fuzzy algebras fullling the samefuzzy identities, dened with respect to fuzzy equalities. We introduce basicnotions and the corresponding operators of universal algebra: construction offuzzy subalgebras, homomorphisms...

Fuzzy logic techniques have been widely used in civil and earthquake engineering applications in the past four decades. However, no thorough research studies were conducted to use them for deriving attenuation relationships for peak ground accelerations (PGA). This paper is an attempt to fill this gap by employing a fuzzy approach with fuzzy sets for earthquake magnitude and distance from sourc...

In the present paper, the idea of braking energy regeneration and reusing that energy during acceleration for a refuse truck is comprehended. According to their driving cycle, the refuse trucks have a good potential for braking energy regeneration. On the other hand, hydraulic hybrid is a powertrain with high power density which is appropriate for energy regeneration. In the primary stage of th...

car body acceleration is an important factor affecting track safety and ride comfort, which are two primary aspects of railway systems. though track level is an important source of wagon body acceleration, no quantitative relation between them is available and the aim of this paper is to propose a method to address this issue. to do so, car body acceleration is determined using a 10 dof simulat...

Dysphagia, a swallowing disorder, is a problem encountered frequently in the rehabilitation of stroke and head injury patients. In normal individuals, safe passage of a food bolus into the esophagus is ensured by laryngeal elevation and closure of the airway. Inadequate laryngeal elevation can lead to aspiration, choking, and even death. The course of recovery in the current clinical practice i...
