The objective of this thesis was to compare various approaches for classification of the `good' and `bad' parts via non-destructive resonance testing methods by collecting and analyzing experimental data in the frequency and time domains. A Laser Scanning Vibrometer was employed to measure vibrations samples in order to determine the spectral characteristics such as natural frequencies and amplitudes. Statistical pattern recognition tools such as Hilbert Huang, Fisher's Discriminant, and Neural Network were used to identify and classify the unknown samples whether they are defective or not. In this work, a Finite Element Analysis software packages (ANSYS 13.0 and NASTRAN NX8.0) was used to obtain estimates of resonance frequencies in `good' and `bad' samples. Furthermore, a system identification approach was used to generate Auto-Regressive-Moving Average with exogenous component, Box-Jenkins, and Output Error models from experimental data that can be used for classification

Background: Endometriosis is a condition characterized by the growth of the endometrium, or the tissue that lines the uterus, outside of the uterus, and it is diagnosed through the presence of endometriotic lesions in the pelvic region. The disease is most often associated with abnormal and painful vaginal bleeding. Currently, minimal literature exists concerning the management of endometriosis in low and middle-income countries (LMICs), which may influence the lack of a cultural competent understanding of menstruation in LMICs and, therefore, a lack of evidence-based policies concerning menstruation.

Methods: Social and cultural barriers influencing endometriosis reporting and management in LMICs were examined through a systematic literature review. Online databases yielded a list of relevant studies. Then, use of MAXQDA, a qualitative data analysis software program, helped to extract and code specific text segments from each study that pertain to the research topic. In-context analysis of coded segments revealed the most common trends, which were organized into broader themes.

Results: Findings demonstrated that social and cultural ideas regarding vaginal bleeding influenced the lack of disease reporting and management of endometriosis in LMICs. Socioeconomic challenges include a lack of hygiene and sanitation measures and education regarding menstruation and vaginal bleeding. Also, many diseases associated with the abnormal vaginal bleeding are often disregarded and not prioritized in clinical settings. It also became clear that cultural taboos regarding menstruation and vaginal bleeding often create feelings of anxiety and fear in women and girls throughout communities in LMICs. However, further research is needed to examine the ways in which women in those communities treat symptoms of irregular vaginal bleeding related to endometriosis.

Conclusions: Socioeconomic, gender, and sex-related factors may influence the ways in which endometriosis is reported and treated and may affect the way the related diseases are understood. Evidence-based policies using a culturally competent understanding of abnormal vaginal bleeding in LMICs may help positively affect the reproductive health of women and girls in such areas.

Breast cancer affects about 12% of women in the US. Arguably, it is one of the most advertised cancers. Mammography became a popular tool of breast cancer screening in the 1970s, and patient-geared guidelines came from the American Cancer Society (ACS) and the US Preventative Task Force (USPSTF).

Breast cancer affects about 12% of women in the US. Arguably, it is one of the most advertised cancers. Mammography became a popular tool of breast cancer screening in the 1970s, and patient-geared guidelines came from the American Cancer Society (ACS) and the US Preventative Task Force (USPSTF). This research focuses on ACS guidelines, as they were the earliest as well as the most changed guidelines. Mammography guidelines changed over time due to multiple factors. This research has tracked possible causes of those changes. Research began with an extensive literature search of clinical trials, the New York Times and the Washington Post archives, systematic reviews, ACS and USPSTF archives.

Description

Science fiction works can reflect the relationship between science and society by telling stories that are set in the future of ethical implications or social consequences of scientific advancements. This thesis investigates how the concept of reproduction is depicted in popular science fiction works.

By questioning methods of sex selection since their early development, and often discovering that they are unreliable, scientists have increased the creative and technological capacity of the field of reproductive health. The presentation of these methods to the public, via published books on timing methods and company websites for sperm sorting, increased interest in, and influence of, sex selection within the global society. The purpose of explaining the history, interest, development, and impact of various sex selection methods in the mid-twentieth century based on the information that is available on them today is to show couples which methods have failed and provide them with the knowledge necessary to make an informed decision on how they choose to go about utilizing methods of sex selection.
