The purpose of this project is to set up a statistical process control (SPC) system in a high volume machining center to reduce the scrap rate and improve the manufacturing quality. The system is demonstrated on a machining center at Waters Corporation as part of a team internship project. This thesis focuses on the gage repeatability and reproducibility study (Gage R&R study) for the implement...
The mechanical behavior of Zr41.25Ti13.75Cu12.5Ni10Be22.5 LM-1 has been extensively characterized under quasistatic loading conditions; however, its mechanical behavior under dynamic loading conditions is currently not well understood. A Split–Hopkinson pressure bar SHPB and a single-stage gas gun are employed to characterize the mechanical behavior of LM-1 in the strain-rate regime of 102–105 ...
Doppler radar data are increasingly used in rainfall-runoff synthesis studies, perhaps due to radar data availability, among other factors. However, the veracity of the radar data are often a topic of concern. In this paper, three Doppler radar outcomes developed by the United States National Weather Service at three radar sites are examined and compared to actual rain gage data for two separat...
Previous studies directed at identifying paclitaxel resistance genes in a paclitaxel-resistant subclone of the human ovarian cancer cell line SKOV-3 identified a novel cancer testis antigen, Taxol resistance-associated gene 3 (TRAG-3). Because investigation suggested that TRAG-3, located on chromosome Xq28, does not directly participate in the paclitaxel-resistant phenotype, it was hypothesized...
The structures are challenged by earthquakes, material degradations and other environmental factors. In order to protect the lives, assets, for maintenance planning, structural health monitoring (SHM) is important. SHM applications, strain gages widely used which have low durability, sensitivity while they high cost. To monitor a structure, large number of be that increases this study, seven co...
به منظور بررسی تلفیق باکتری های محرک رشد و کود شیمیایی بر عملکرد و کیفیت شلغم علوفه ای، آزمایشی در مزرعه پژوهشی موسسه تحقیقات برنج کشور (رشت) در قالب طرح بلوک های کامل تصادفی در سال زراعی90- 1389 انجام شد. تیمارهای مورد بررسی در این تحقیق شامل تیمار بدون کود و بدون تلقیح (شاهد)، استفاده از کود کامل شیمیائی و بدون تلقیح، تلقیح با azotobacter chroococcum strain 41 و بدون کود نیتروژن، تلقیح با a. ...
Fiber optic Bragg gratings packaged in long gage configurations are being used to measure static and dynamic macro-strains in structures and structural models to monitor structural health and detect and identify macrodamage incurred from a seismic event. These long gage sensors are being used to experimentally verify analytical models of small-scale structural models in their preand post-damage...
A silicon force sensor is realized in which the force is measured by compressing a meander shaped polysilicon strain gage. A second gage which is not loaded, is used for temperature compensation, for compensation of bending and stretching stresses in the chip and for common changes in zero load resistor values. It is shown that the output of the bridge is a linear function of the force and is i...
A small and lightweight signal conditioning unit for use with strain-gage transducers is described. The unit provides bridge-balancing, amplification, and filtering for three channels of Wheatstone bridge circuits. The electronics are housed with a 4.5 cm x 3.0 cm x 2.5 cm box that allows connection to a transducer and to a cable that extends to power supplies and a data storage facility. Evalu...
