This paper puts forward the overall scheme of CNC System Reliability Testing base on the SCADA(Supervisory Control And Data Acquisition) system,introduces to the principle and sets up the physical system According to the selected hardware and software of data acquisition system and data storage system.It selects the mechanical load set load simulation method according to the characteristics of the test sample size is bigger. Using UG software to design and install to loading plate ,and tested.At present,The system of test has run with the safe operation of the normal,and obtain actual measured data about the reliability of CNC system.

This study examined the effects of two designs of rigid foot orthoses on plantar pressure measurements and identified differences between the devices. While wearing modified Root- and Blake-style orthoses, 27 subjects were examined with the Electrodynogram (EDG) in-shoe pressure measurement system. Reliability testing was performed on the EDG data. Significant changes were observed in the temporal parameters of gait when subjects wore the orthoses. When the devices were used, the duration of some of the components of stance phase was altered, and the initiation of loading beneath the medial forefoot was delayed. A reduction in the total duration of loading at discrete sites beneath the heel and forefoot was also observed. The effects of the two orthoses were similar, with only small differences observed between the devices. (J Am Podiatr Med Assoc 91(4): 184-193, 2001)

This research goal is to identification and evaluation influence of work motivation and work environment to employee’s performance in BAPPEDA Kabupaten Wonosobo. The object of this research is 37 employees of Badan Perencanaan Pembangunan Kabupaten Wonosobo. And the location of this research is at Badan Perencanaan Pembangunan Kabupaten Wonosobo. The analysis used is test validity, reliability testing, and test the hypothesis, with the help of the computer program SPSS version 17, using multiple linear regression analysis. Based on calculations of data and analysis used, the regression equation is obtained: Y = 11.733 + 0.320 X1 +0.334 X2 + ε, by using the equation regression analytical method can conclude that (X1) take effect positively against employees performance. With t value in amount of 2,219 (bigger than t in table in amount of 1,690) and significance value in amount of 0,33. By applying significance limited value in amount of 0,05, it means, hypothesis that claim if work motivation take effect against employees performance can be accepted. There is a positive and significant correlation between work environment variables (X2) against employees. With t value in amount of 2,219 (bigger than t in table in amount of 1,690) and significance value in amount of 0,33 (smaller than 0,5). Simultaneously, work motivation take effect positively and significantly against employees performance with the F value in amount of 11,562 (bigger than 0.05), then obtained significance value 0.000. It can be concluded that the work motivation and work environment has a positive and significant influence on employee performance in BAPPEDA Kabupaten Wonosobo.

AbstractThis paper describes the results of extensive performance and reliability characterization of a silicon-based surface micro-machined tunable optical filter. The device comprises a high-finesse Fabry-Perot etalon with one flat and one curved dielectric mirror. The curved mirror is mounted on an electrostatically actuated silicon nitride membrane tethered to the substrate using silicon nitride posts. A voltage applied to the membrane allows the device to be tuned by adjusting the length of the cavity. The device is coupled optically to an input and an output single mode fiber inside a hermetic package. Extensive performance characterization (over operating temperature range) was performed on the packaged device. Parameters characterized included tuning characteristics, insertion loss, filter line-width and side mode suppression ratio. Reliability testing was performed by subjecting the MEMS structure to a very large number of actuations at an elevated temperature both inside the package and on a test board. The MEMS structure was found to be extremely robust, running trillions of actuations without failures. Package level reliability testing conforming to Telcordia standards indicated that key device parameters including insertion loss, filter line-width and tuning characteristics did not change measurably over the duration of the test.
