Structural Features Related to Tree Crotch Strength

Farrell, Robert William 11 June 2003 (has links)
Crotches were cut out of red maple (Acer rubrum), callery pear (Pyrus calleryana), and sawtooth oak (Quercus acutissima) trees (2.5â -7â d.b.h.) and then pulled apart in an engineering testing machine to identify physical parameters correlated with crotch strength. Parameters measured included the diameter of the branch and of the trunk above and below the crotch, angle of the branch and branch bark ridge, and the length of the crotch and the branch bark ridge. The force required to break each sample was used to calculate breaking strength based on the formula for bending stress. Each parameter was tested for correlation with crotch strength within the individual species and for the three species combined. The ratio of branch diameter over crotch width had the highest correlation coefficient for crotch strength. Branch angle was also correlated with crotch strength but not as highly as the ratio of the diameters. V-shaped crotches (those with included bark) were significantly weaker than U-shaped crotches for all species. The ratio of the two stem diameters greatly influenced the manner in which the crotches broke. In crotches where the branch diameter was 2/3 the size of the trunk or smaller, the crotch broke by being pulled directly out of the trunk. Crotches with branches more than 2/3 the diameter of the trunk broke when the trunk split longitudinally and had significantly lower strength values. These results indicate that increased crotch strength results from a small branch diameter relative to that of the trunk. / Master of Science

A Study of Pupil Failures as they Exist in the Senior High School of Stamford, Texas

Flemins, Mabel Bryan 08 1900 (has links)
The purpose of this study was threefold: (1) to determine the degree of pupil failure as it exists in the Senior High School, Stamford, Texas; (2) to consider the extent to which the "basic factors" of failure contribute to pupil failure in this school; and (3) to submit suggestions as to how pupil failure may be reduced to a minimum in the Stamford Senior High School.

Using Generic Telemetry Prognostic Algorithms for Launch Vehicle and Spacecraft Independent Failure Analysis Service

ITC/USA 2009 Conference Proceedings / The Forty-Fifth Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2009 / Riviera Hotel & Convention Center, Las Vegas, Nevada / Current equipment and vehicle failure analysis practices use diagnostic technology developed over the past 100 years of designing and manufacturing electrical and mechanical equipment to identify root cause of equipment failure requiring expertise with the equipment under analysis. If the equipment that failed had telemetry embedded, prognostic algorithms can be used to identify the deterministic behavior in completely normal appearing data from fully functional equipment used for identifying which equipment will fail within 1 year of use, can also identify when the presence of deterministic behavior was initiated for any equipment failure.

From failure to flourishing: a cognitive, emotional, and behavioral model

North, Rebecca Jeanne 22 October 2010 (has links)
Two studies were conducted to examine if and how failure can lead to subsequent psychological flourishing. Both studies used the context of individuals’ biggest job-related failure or most significant challenge to test a proposed model of adaptive response to failure. Specifically, it was proposed that, at a cognitive/emotional level, an adaptive response to failure is characterized by acceptance of negative emotions and self-acceptance. Further, it was proposed that at a behavioral level, an adaptive response to failure involves goal disengagement coupled with goal reengagement, including reengaging with new goals that are intrinsically meaningful. These complementary studies both examined the relationship between individuals’ response to failure and psychological flourishing. Studies were conducted with different participant samples and used complementary designs to provide converging evidence for the proposed model. Using a random sampling process to recruit participants, Study 1 (N = 50) consisted of semi-structured interviews with individuals from the Austin community. Study 2 (N = 101) was an online study and consisted of a series of questionnaires and a writing task. Analyses were conducted on interviews, questionnaires, and writings to examine the relationships between response to failure, including acceptance of negative emotions, self-acceptance, goal disengagement, and goal reengagement, and psychological flourishing. Overall, findings underscored the significance of acceptance and goal reengagement in predicting psychological flourishing after failure. Goal reengagement, in particular, consistently predicted subsequent flourishing. Results also indicated that in response to failure, both persistence toward meeting established goals and moving beyond established goals can lead to subsequent flourishing. These findings imply that flexibility, rather than adherence to a singular response, may be adaptive in responding at a behavioral level to failure. Furthermore, results showed that failures characterized by higher emotional distress can lead to greater subsequent psychological flourishing than failures characterized by low levels of emotional distress. Overall, both studies demonstrate that failure, when responded to in an adaptive way, can lead to a broad range of positive psychological outcomes. / text
