Expert System-Type Approach To Voice Disorders: Scheduling Botulinum Toxin Treatment For Adductor Spasmodic Dysphonia, Anthony P. Salvatore, Amitava Biswas, Vladik Kreinovich, Bertha Manriquez, Michael P. Cannito, Robert J. Sinard

Departmental Technical Reports (CS)

One of the most debilitating disorders is adductor spasmodic dysphonia (ADSD), a voice disorder caused by involuntary movements of the muscles of the larynx (voice box). For treating ADSD, botulinum toxin (BT) injections turned out to be very useful. However, the effects of BT are highly variable, so at present, there is no objective criterion of when such a BT treatment is necessary. It is therefore desirable to develop such a criterion.

In this paper, we show that traditional statistical techniques are unable to generate such a criterion, while a natural expert system approach seems to be capable of generating …

Global Challenges As Inspiration: A Classroom Strategy To Foster Social Responsibility, Linda Vanasupa, Lynn Slivovsky, Katherine C. Chen

Materials Engineering

Social responsibility is at the heart of the Engineer’s Creed embodied in the pledge that we will “dedicate [our] professional knowledge and skill to the advancement and betterment of human welfare...[placing] public welfare above all other considerations.” However, half century after the original creed was written, we find ourselves in a world with great technological advances and great global-scale technologically-enabled peril. These issues can be naturally integrated into the engineering curriculum in a way that enhances the development of the technological skill set. We have found that these global challenges create a natural opportunity to foster social responsibility within the …

Nanotechnology, Biology, Ethics And Society: Overcoming The Multidisciplinary Teaching Challenges, Linda Vanasupa, Matthew Ritter, Barbara Schader, Katherine C. Chen, Richard N. Savage, Peter Schwartz, Lynne Slivovsky

Materials Engineering

One of the inherent challenges of teaching any emerging technology like nanotechnology, is the fact that its core competencies flux in the new disciplines' early stages. Nanotechnology presents an additional challenge in that its underpinnings cross multiple traditional disciplinary boundaries. We have designed a course that aims to address some of these challenges through a handful of structural features: team-based learning; a "reverse of the learning pyramid" approach; team-teaching; embedded information literacy techniques; and application-centered content. Our course is organized around four applications that are in their developmental stages: gold nanoshells for cancer treatment; molecular manufacturing; tissue engineering of a …

Multicomponent Patterning Of Nanocomposite Polymer And Nanoparticle Films Using Photolithography And Layer-By-Layer Self -Assembly, Javeed Shaikh Mohammed

Doctoral Dissertations

In this dissertation, the fabrication, characterization, and application examples of 3D multicomponent nanocomposite micropatterns (MNMs) with precise spatial arrangements are described. The ability to produce such small-scale 3D structures with versatility in composition and structure is a new development based on the integration of nanoscale layer-by-layer (LbL) self-assembly and microscale photolithographic patterning, enabling construction of surfaces with microscale patterns that possess nanotopographies. The techniques used here are analogous to surface micromachining, except that the deposition materials are polymers, biological materials, and colloidal nanoparticles used to produce 3D MNMs. A key feature of the resulting 3D MNMs is that the physical …

The Effect Of Gender Schematicity On The Assessment Of Male And Female Pilots’ Competence Given Identical Scenarios, Jan D. Laplante

Master's Theses - Daytona Beach

Gender has been identified as one of the top three categories, along with race, and age that are subject to stereotyping, prejudice and discrimination (Fiske, 1998). With the emergence of women in stereotypical male domains, gender research has never been more important. The aviation community is a prime example of one such domain.

This study examined the presence of an existing perception that male pilots are more competent then female pilots. It suggested that there does not appear to be evidence that would explain why there should be a difference in this perception of competence. It also discussed social theories …

A Study On Perceptions Of Civil Engineers Regarding Mandatory Continuing Education, Alee A. Sleymann

Dissertations

This study explored the perceptions of civil engineers regarding continuing professional competency requirements for license renewal. In this study,continuing professional competency is assumed to have a direct relationship to public welfare and safety. The policy of mandatory continuing education was adopted primarily for this reason. Currently, mandatory continuing education is adopted by 29 states as the method of assuring continued professional competency.

Many professionals, however, have not welcomed this mandatory continuing education (MCE) policy. The reason for this opposition is the claimed ineffectiveness of this policy in fostering continued competency. In addition, the regulatory boards and policy advocates have not …

A Quantitative Model Of Error Accumulation During Pcr Amplification, Elsje Pienaar, M. Theron, M. Nelson, Hendrik J. Viljoen

Hendrik J. Viljoen Publications

The amplification of target DNA by the polymerase chain reaction (PCR) produces copies which may contain errors. Two sources of errors are associated with the PCR process: (1) editing errors that occur during DNA polymerase-catalyzed enzymatic copying and (2) errors due to DNA thermal damage. In this study a quantitative model of error frequencies is proposed and the role of reaction conditions is investigated. The errors which are ascribed to the polymerase depend on the efficiency of its editing function as well as the reaction conditions; specifically the temperature and the dNTP pool composition. Thermally induced errors stem mostly from …

Semiempirical Electromagnetic Modeling Of Crack Detection And Sizing In Cement-Based Materials Using Near-Field Microwave Methods, Jagadish Nadakuduti, Genda Chen, R. Zoughi

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Detection and characterization of cracks in cement-based materials is an integral part of damage evaluation for health monitoring of civil structures. Microwave signals are able to penetrate inside of dielectric materials (e.g., cement-based materials) and are sensitive to local, physical, geometrical, and dielectric variations in a structure. This makes microwave nondestructive testing and evaluation (NDT&E) techniques suitable for inspection and health monitoring of civil structures. Near-field microwave NDT&E techniques offer the added advantage of providing high spatial resolution, requiring simple hardware that may be portable, low power, fast, real time, and robust. Additionally, these techniques are noncontact and one-sided. Besides …
