Why Toyota And Honda Topped The 2002 J.D. Power Quality Study, Susan Lightle, Kenneth Yale Rosenzweig, John Talbott
Why Toyota And Honda Topped The 2002 J.D. Power Quality Study, Susan Lightle, Kenneth Yale Rosenzweig, John Talbott
Kenneth Y. Rosenzweig
Toyota again topped the annual J. D. Power and Associates quality study released in late May of 2002. Toyota scored the highest mark ever with l 07 defects per l 00 vehicles, while Honda came in second with 113 defects. The study was based on responses of approximately 65,000 new car owners queried during their first 90-days of ownership. These results do not surprise us, as we have been fortunate to make numerous sojourns to the Toyota plant in Georgetown, Kentucky, and observe the manufacturing processes. These trips were normally facilitated by a former Japanese student of ours, Minako Yanke, …

Mechanical surface enhancement techniques such as cavitation peening (CP) have various design parameters which can affect the fatigue performance of the part. In this study, a full factorial design of experiment is applied to investigate the effects of cavitation peening process parameters on the fatigue performance of carburized steel. These parameters include standoff distance, cavitation number, nozzle size, and exposure time. The response variables considered in this experiment include residual stress, surface roughness and austenitic ratio. Results obtained from full factorial design of experiment method were compared with the results from literature which applied Taguchi method. The comparison revealed that …
A Comparison Between Single And Dual Monitor Productivity And The Effects Of Window Management Styles On Performance, Alex Stegman, Chen Ling, Randa Shehab
A Comparison Between Single And Dual Monitor Productivity And The Effects Of Window Management Styles On Performance, Alex Stegman, Chen Ling, Randa Shehab
Dr. Chen Ling
Several research studies have been published on user opinion and productivity of using dual monitor systems. These studies found that users typically enjoy using multiple monitors, but none found a strong increase in performance and productivity. Other researchers have focused on improving multiple monitor usability, but often without any statistical framework. This study compared single and dual monitor productivity measures: task time, cursor movement, and number of window switches. Additionally, window management styles (WMS) were studied in order to help designers understand user behavior better. WMS were broken into two categories, toggler and resizer, and then compared to the WMS …
A Nano-Cheese-Cutter To Directly Measure Interfacial Adhesion Of Freestanding Nano-Fibers, Xin Wang, Johnny F. Najem, Shing-Chung Wong, Kai-Tak Wan
A Nano-Cheese-Cutter To Directly Measure Interfacial Adhesion Of Freestanding Nano-Fibers, Xin Wang, Johnny F. Najem, Shing-Chung Wong, Kai-Tak Wan
Dr. Shing-Chung Josh Wong
A nano-cheese-cutter is fabricated to directly measure the adhesion between two freestanding nano-fibers. A single electrospun fiber is attached to the free end of an atomic force microscope cantilever, while a similar fiber is similarly prepared on a mica substrate in an orthogonal direction. External load is applied to deform the two fibers into complementary V-shapes, and the force measurement allows the elastic modulus to be determined. At a critical tensile load, “pull-off” occurs when the adhering fibers spontaneously detach from each other, yielding the interfacial adhesion energy. Loading-unloading cycles are performed to investigate repeated adhesion-detachment and surface degradation.
