Development of optical diaphragm deflection sensors

The objective of this project was to develop high-temperature pressure sensors using non-metallic components and optical sensing methods. The sensors are to operate over a temperature range from room temperature approx. 20C to 540C, to respond to internal pressure up to 690 kPa, to respond to external pressure up to 690 kPa, and to withstand external overpressure of 2070 kPa. Project tasks include evaluating sensing techniques and sensor systems. These efforts include materials and sensing method selection, sensor design, sensor fabrication, and sensor testing. Sensors are tested as a function of temperature, pressure, overpressure, and vibration. The project results show that high-temperature pressure sensors based on glass components and optical sensing methods are feasible. The microbend optical diaphragm deflection sensor exhibits the required sensitivity and stability for use as a pressure sensor with temperature compensation. for the microbend sensor, the 95% confidence level deviation of input pressure from the pressure calculated from the overall temperature-compensated calibration equation is 3.7% of full scale. The limitations of the sensors evaluated are primarily due to the restricted temperature range of suitable commercially available optical fibers and the problems associated with glass-to-metal pressure sealing over the entire testing temperature range

Case Study: Investigation into the Ownership of Jean-Honore Fragonard\u27s Blind Man\u27s Buff (1750-1752)

During World War II, Nazis stole 60,000 pieces of Jewish-owned cultural valuables from French collections. German leaders were fascinated with art and saw it as a vehicle to bolster their status and power. Art was specifically stolen on behalf of Adolf Hitler, who intended to build his own museum: the Fuhrermuseum. One of the most influential families in France at that time was the Rothschild family. During World War II, the Jewish family was forced to flee their home while over 3,500 pieces of artwork from the Rothschild collection were stolen. Most were never recovered. I suspect that Jean Honoré Fragonard’s Blind Man’s Buff is one of them. The archives from the Jeu de Paume identify many Fragonard paintings, once owned by the Rothschilds, which were seized by the Einsatzstab Reichsleiter Rosenberg (ERR) Nazi agency. The provenance of Fragonard’s Blind Man’s Buff, now owned by Toledo Museum of Art, has missing dates and gaps in its timeline, specifically during the seizure of the Rothschilds collections. Evidence indicates the painting was owned by the Rothschild family, at the very latest by 1915. Its next appearance is in New York in 1954, where it is sold and donated to the Toledo Museum. Although Toledo’s Blind Man’s Buff is not mentioned in the Jeu de Paume records, the question of the provenance still exists. Where was the Toledo painting during this time period and how did it get to New York? Due diligence is required of art dealers, collectors, and museums to investigate the provenance and provide answers. This case study intends to trace the history and location of Blind Man’s Buff

Exploring Interpersonal, Sexual, and Moral Development of Offending Clergy

This study explored the lived experiences of offender clergy through their childhood development. It specifically looked at the social, moral, and sexual development of these individuals. This phenomenological qualitative study provided insight into what, if anything, in their early moral, social, and sexual development could help shed light on their future behaviors and actions. Bandura’s Social Learning Theory guided this study by providing an understanding of how social learning throughout development can influence the formation of social, moral, and sexual behaviors later in life. The data were collected from reviewing existing material from existing diaries, interviews, and previously published studies. The information was coded and analyzed within the context of the social, moral, and sexual development of the participants. The findings indicated a similarity in themes across most, if not all, participants. The relative themes included religious moral upbringing, authoritarian fathers, sexuality is immoral, special maternal relationships, and awkward social relationships. Ramifications for positive social change included the understanding of the circumstances that may help shape an individual’s predisposition to commit these offenses while in positions of power. This will help form early intervention strategies and shift resources from reactionary to preventative measures

Conditional Reasoning: Scenario or Context Effects?

This Paper was presented at the Fifth Conference of the European Society for Cognitive Psychology - ESCOP, celebrated in Paris, Societé Francaise de Psychologie-Université de Paris-SUD (September, 12-16, 1992).This paper studies the importance of contextual factors in reasoning with conditional inference tasks. In this experiment subjects were given conditional sentences in the context of narrative texts. Short stories about scenarios of the daily life were described in these texts. The experiment manipulated: a) context (causal or promises/threats), b) degree of factual relation between antecedent and consequent of conditional (deterministic, probabilistic or without relation), c) congruence between the factual consequence explicit in the story and the logic conclusion and d) conditional rules. The results were related to previous investigations about syllogistic inference (Valiña & De Vega, 1988) and were discussed within the framework of theoretical modes about pragmatic reasoning

Galaxies with Background QSOs, I: A Search for Strong Galactic H-alpha Lines

A search for emission lines in foreground galaxies in quasar spectra (z(gal) < z(QSO)) of the Sloan Digital Sky Survey (SDSS) data release 5 (DR5) reveals 23 examples of quasars shining through low redshift, foreground galaxies at small impact parameters (< 10 kpc). About 74,000 quasar spectra were examined by searching for narrow H{\alpha} emission lines at z < 0.38, at a flux level greater than 5 \times 10^-17 ergs cm^-2 s^-1, then confirming that other expected emission lines of the H II regions in the galaxy are detected. The galaxies were deblended from the quasar images to get colors and morphologies. For cases that allow the galaxy and the quasar to be deblended, the galaxies are blue (0.95 <(u-r)< 1.95). Extinction and reddening through the galaxies is determined from the (g-i) color excesses of the quasars. These reddening values are compared with the flux ratio of H{\alpha} to H{\beta}, which reflect the extinction for an undetermined fraction of the sightline through each galaxy. No trends were found relating E(B-V)_(g-i), impact parameter (b), and (u-r) for the galaxies or between E(B-V) derived from (g-i) and that derived from H{\alpha}/H{\beta}. Comparison with previous studies of quasar absorption systems indicate our sample is more reddened, suggesting disk-dominated absorber galaxies. Measurement or limits on galactic, interstellar Ca II and Na I absorption lines are given from the quasar spectrum. No trends were found relating Ca II equivalent width (W (Ca II)) or Na I equivalent width (W (Na I)) to b, but a correlation of r_s = -0.77 ({\alpha} = 0.05) was found relating W (Ca II) and E(B-V)(g-i)
