Frequency Locking of Two Laser Diodes to Femtosecond Frequency Comb-Frequency standard of THz

Wang, Chih-Yu 17 July 2006 (has links)
Phase locking of external-cavity diodes laser¡]ECDL¡^ to the stabilized optical frequency combs of a femtosecond mode-locked laser. Optical frequency combs of a femtosecond mode-locked laser can be the reference standard of dual-wavelength external-cavity diode lasers (ECDLs). Frequency stabilization of two external-cavity diode laser is also demonstrated simultaneously.Suppression of the frequency fluctuation of two ECDLs from hundreds MHz to 200 Hz is demonstrated and characterized. Meanwhile, frequency tunable continuous-wave Tera-Hertz (cw THz) wave is generated and observed by photomixing of the output of two frequency stabilized ECDLS with tunable relative frequency difference on a photoconductive antennas. In our experiment, cw THz wave is demonstrated and with tuning range from 0.200 to 1.240THz and could be attribute as frequency standard of THz.

The Determinants of Geographic Concentration in Taiwan Manufacturing Industries

Fang, Jing-yi 21 July 2006 (has links)
This study focuses on the determinants of agglomerations, natural advantages, spillovers, and transaction costs respectively, and intends to form a location choice model with those agglomerative factors. Besides, we examine the geographic concentration scope overall and by region with the data set of manufacturing industries in Taiwan in 2003. We also explore some interesting empirical results. First, the overall geographic concentration level is slightly decreasing through 1996 to 2003. Second, the plants in the South and Middle regions of Taiwan are more concentrated than those in the North region. And each region has its own specific characteristic that draws different types of industries to locate. Third, with OLS regression we find that outsourcing dependence variable applied to proximate transaction costs effect is the most significant of all and represents that transaction costs have large influence to agglomeration scope. Finally this model can be improved from some aspects of involving distance into consideration and extending to entrepreneur across countries.

A study between Trust, Delegation and job satisfaction

Han, Nien-Chia 29 January 2007 (has links)
The effectiveness of manager¡¦s management leadership is potentially affected by the interpersonal interactions with and delegation to its employees. At the same time, the level of employee job satisfaction is also affected by such relationships. How much trust does a supervisor has in this subordinate? What level of delegation is exercised by supervisors? In a business organization, what kinds of relationships exist between supervisor¡¦s trust in employees, delegation to employees and employee job satisfaction? When a supervisor¡¦s trust in and delegation to employees are met with employee with orientation toward theory X, or theory Y, what kinds of relationships exist for internal and external job satisfaction? Two sets of samples were collected in this study. One set of data were collected from a group of Taiwanese employee, the other set from a group of Chinese employee employed by Taiwanese business enterprises in the Gungdong district of China. The results of the two groups in different geographic regions were compared. Differences in trust, delegation and employee job satisfaction in the two groups with similar Chinese culture were identified. The research findings are as follows: 1. Trust and delegation are moderately and positively correlated. In this relationship, the Taiwanese employee group exhibits no significant difference with the Chinese employee group.¡@The correlation for this relationship was not highly correlated in for both employee groups. 2. Trust and employee overall job satisfaction showed moderate positive relationship. The results indicate that the Chinese employee group exhibit higher level of job satisfaction relative to the Taiwanese employee group in respect of trust. In the Taiwanese employee group, there was no significant difference between internal and external job satisfaction. But in the Chinese employee group, internal job satisfaction was higher than external job satisfaction with respect to trust. 3. In the sample of Chinese employee studied, there was no employee with theory X orientation. In the Taiwanese employee group, when theory X and Y was introduced as a factor moderating the relationship between trust and internal job satisfaction, employee with theory Y orientation showed higher level of internal job satisfaction with respect to trust than employee with theory X orientation. For both groups of employee with theory Y orientation, the Chinese employee group showed higher level of internal job satisfaction than the Taiwanese employee group. 4. Delegation and overall job satisfaction showed moderate level of positive relationship. There was no difference between the Taiwanese and Chinese employee group. 5. The relationship between delegation and internal and external job satisfaction was moderated by theory X and Y orientation. In this study, the Chinese employee group has no employee with theory X orientation. In the Taiwanese employee group, employee with theory Y orientation exhibit higher level of correlation between delegation and internal job satisfaction than employee with theory X orientation. In both groups of theory Y orientation, there was no significant difference between the Chinese and Taiwanese employee group with respect to internal job satisfaction. With respect to the relationship between delegation and external job satisfaction, in the Taiwanese employee group, the correlation between delegation and external job satisfaction for employee with theory Y orientation was much higher than that for theory X. For both groups of theory Y, the internal job satisfaction in Taiwanese employee group was higher than the Chinese employee group. This study reviews the relationship between supervisor¡¦s trust and delegation with respect to subordinate¡¦s level of job satisfaction. The results serve as reference for supervisors and managers in their management or leadership. For the business managers and supervisors of Taiwanese business enterprises in China, this study has made comparison between the Taiwanese group and Chinese group, which may be beneficial in understanding the organizational behavior of local Chinese employee when considering investment in China.

An Investigation On Compatibility Properties Of Exterior Finish Coats For Insulated Walls In Terms Of Water Vapour Pemeability And Modulus Ofelasticity

Ors, Kerime 01 September 2006 (has links) (PDF)
The compatibility properties of some contemporary finish coats together with their complementary layers used in insulated exterior walls were examined in terms of water vapour permeability and modulus of elasticity. Basic physical and mechanical properties of some synthetic-, cement- and polymer-based external finish coats were analyzed in laboratory. Some additional samples, complementing the wall section, were also examined for their water vapour permeability. Results showed that the finish coats were high vapour permeable although they had high resistance to water vapour permeation, which was achieved by their application in thin layers. Cement-based undercoats were found to be medium permeable. The application of primer and/or paint was found to decrease the permeability of finish coats in different ranges. Thermal insulation layer was found to interrupt water vapour flow considerably. Among polystyrene- and mineral-wool-based thermal insulation boards, rockwool was recommended as the insulation layer due to its medium vapour permeability. In conclusion, walls insulated externally with rockwool boards and plastered with polymer-based finish coat, FC8ACB or synthetic-based finish coat FC3SB were found to be the most proper combination in terms of breathing and thermal resistance capabilities. All finish coats seemed to have sufficient strength and except the synthetic-based finish coat, FC2SB, they seemed to be compatible with each other and with the masonry in terms of their Emod values. Further studies were recommended on some other compatibility properties of finishing systems, such as thermal and moisture dilatation properties, and on the relation between the resistance to water vapour permeation and water permeability.

The Effects Of Positive Core Self And External Evaluations On Performance Appraisals

Guven, Lale 01 December 2007 (has links) (PDF)
The purpose of this study was to investigate the effects of core self-evaluations (CSEs) and core external-evaluations (CEEs) on performance evaluations. It was hypothesized that people with higher levels of CSEs and CEEs would be more lenient in their performance ratings, when rating neutral performance. The second hypothesis of the study was that people with higher and lower CSEs would engage more in halo when rating neutral performance compared to people with average levels of CSEs. It was further hypothesized that CEEs would moderate the relationship between CSEs and performance ratings given. A total of 129 students from the Middle East Technical University participated in this study. They were given the core self- and external-evaluations scales, as well as two distractor scales (PANAS and Rosenberg Self-Esteem Scale). They were later assigned randomly to either the neutral or the good performance vignette conditions, and asked to rate the performance of a departmental secretary whose performance was described in the vignette using two different performance rating forms that included the relevant performance dimensions and behaviors of the secretary. The first one of these forms is the Behavior Observation Scale (BOS) and the second one is the Graphic Rating Scale (GRS). The results showed that CSEs did not have a significant effect on the performance evaluations given. When the mood of the participants was controlled, however, people who had higher CSEs gave lower performance ratings to neutral performance than people who had lower CSEs, with the GRS as the rating form. Thus, the first hypothesis was not supported and even an opposite effect emerged. The second hypothesis found no support, as the standard deviations of the performance ratings given by people with high, low or average CSEs did not differ significantly from each other for the neutral performance vignette condition, even when the mood of the participants was controlled. However, the standard deviations of the ratings given by participants with average CSEs were higher than that of the participants with low and high CSEs for the good performance vignette condition. Hypothesis three was not supported either, as CEEs were not found to moderate the relationship between CSEs and the performance ratings.

Seismic Upgrade Of Deficient Reinforced Concrete Frames Using External Systems

Ozkok, Mustafa Emre 01 June 2010 (has links) (PDF)
There is a large building stock in seismic regions of Turkey that require seismic upgrades. In order to minimize the disturbance to occupants and not to intervene with the functioning of the building, external strengthening methods can be preferred among different alternatives. This study reports the experimental findings on the upgrading of deficient reinforced concrete frames with external installed structural components. Specimens strengthened with an externally reinforced concrete shear wall, external steel frames, steel plate shear wall and one as-built reference 1/3-scale portal frame specimens were tested under constant gravity load and increasing cyclic displacement excursions. The RC frames had deficiencies those mimic the existing deficient building stock in Turkey. The test results showed that the external upgrading can increase both the lateral stiffness and strength of deficient RC frames considerably. Finite element analyses were conducted to specimen models to investigate the behaviors numerically. Furthermore, corresponding single degree of freedom (SDOF) models of specimens were generated to perform dynamic analysis. Results show the importance of hysteretic response and enhancement of energy dissipation capability with drift control.
