Traditional organic chromophores and polymers with disc-like, coplanar geometry tend to be highly emissive in the dilute solutions but become weakly luminescent in the concentrated solution and solid states. On the contrast, conventional chromophores (such as silole) with non-coplanar structure exhibit strong fluorescence in the concentrated states due to the aggregation-induced emission (AIE) or AIE enhancement (AIEE) effect originated from the restricted intramolecular rotation (RIR) inherent from the chemical structures of the luminescent materials. To verify the influence of RIR on the AIEE properties, four approaches were attempted in this research. First, copolymers PFN with alternative fluorene-naphthol unit was prepared through facile Suzuki coupling and was characterized to have AIEE properties due to the hydrogen-bond (H-bond) interactions among the inherent hydroxyl (OH) groups of the naphthol units. The H-bond interactions of PFN copolymer effectively restrict the molecular rotations and experimental variables (such as increasing solution concentration, introducing non-solvent water to solution, cooling and applying shearing forces during solvent evaporation stage etc.) effective in promoting the H-bond interactions result in the emission enhancement. Second, the fluorescent PFN was blended with poly(vinyl pyrrolidone) (PVR) through facile hydrogen-bond (H-bond) interactions. By the effective H-bond interactions between the OH groups of PFN and the carbonyl functions of PVR. The molecular rotations of PFN can be effectively locked by large amounts of carbonyl groups in PVR. With the efficient H-bond interactions, the PFN/PVR blend with the low content (2.33 wt%) of fluorescent PFN component actually has a high quantum efficiency of 0.93, comparatively higher than other blends containing higher fluorescent PFN. Third, novel vinyl polymer PTP with pendant AIE-effective tetraphenylthiophene (TP) group was prepared through radical polymerization. The resultant PTP polymer exhibits two discernible emission bands corresponding to monomer and aggregate emissions, respectively. The relative monomer to aggregate emission intensity of the PTP polymer in either the solution or the solid state depends strongly on the extent of aggregations. Increasing solution concentration results in the increasing extent of aggregation and the increasing aggregate/monomer emission ratio and also, the large emission enhancement due to the AIEE effect. Finally, the TP-derived ammonium (TP-NH3+) cations are complexed with poly(sodium vinylsulfonate) (PSV) polyanion to generate ionic PSV-TP(x/y) systems with long-range electrostatic interactions between the cationic ammonium of TP-NH3+ and the polyanion of PSV. The fluorophoric TP units are associated with each other to form large aggregate domains stabilized by the long-range interactions. Introduction of water into dilute solution of PSV-TP in THF resulted in self-aggregated nanoparticles and the accompanied emission enhancement due to AIEE effect. Introduction of excess PSV polyanions promoted the self-aggregation of the TP fluorophores and resulted in the fluorescence enhancement. Nevertheless, addition of NaCl electrolytes causes the dissociations of the TP aggregates and the corresponding emission reduction. By controlling the additive, the blended PSV-TP film containing excess PSV has a high quantum yield of £XF = 0.83. In addition, the ionic PSV-TP complex film possesses high spectral stability without spectral variations after annealing at a high temperature of 270 oC.

Whether it is Forbes, The Globe & Mail, The Wall Street Journal or Harvard Business Review, one can¡¦t help but notice that most accounts of business mergers are about what went wrong! In fact, over 70% of all mergers and acquisitions fail to achieve original financial expectations. That is a traumatic statistic. Additionally, although the merging entities give a great deal of importance to financial matters and the outcomes, HR issues are the most ignored ones. To be ironical, many studies have shown that most of the mergers fail to bring out the desired outcomes due to ¡§people-related¡¨ issue. The uncertainty brought out by poorly managed HR issues in mergers and acquisitions have been the major reason for these failures. The human resource issues in the mergers and acquisitions (M&A) can be classified in two phases the pre-merger phase and the post merger phase. Some literature provides ample evidence of difference in between the human resource activities in the two stages: the pre-acquisition and post acquisition period. However, we will focus on post acquisition period. The post acquisition period involves an assessment of the cultural and organizational differences, which will include the organizational cultures, role of leaders in the organization, and the management styles. The usual impacts, such as high turnover rate, decrease in the morale, motivation, and even lead to M&A failures. The other issues in the M&A activity are the changes in the HR policies, downsizing, layoffs, stress on the workers, and information system issues. As a result, human resource system issues in M&A activity are occupying a crucial position, indeed, human resource planning, compensation designs, performance appraisal system, employee development and employee relations should be given in the priority. Beside, the M&A activity also causes changes in their well defined career paths and future opportunities in the organization. Some employees also have to be relocated or assigned new jobs. Accordingly, HR will place employees in a completely different situation with new job profiles and work teams or design the job rotation programs. This may pose a tremendous impact on the performance of the employees. Therefore, HR may also need to develop a variety of training system and communication system to rebuild self-esteem of each employee. Those programs will enhance employees to obtain ability and create their potentials. Finally, the compensation structure among the organizations may also have a unavoidable difference, for example, one of firms may have performance based pay while other may have higher component of fixed pay; Hence the differences in compensation structure and performance appraisal systems also need to be re-evaluated so as to bring equity in the human resource systems and to treat employees at the equal level. Simultaneously, the employee relations issues will gain more importance in the acquisitions of Taiwan¡¦s industries. The power equation between management and unions is bound to change with the acquisition. The acquiring management also needs to keep track of number of unions in the workplace and equations between HR department and unions. Hence, developing a harmony relationship should be put in the first place. To sum up, this will require study of management-union equation, employee contracts, political linkages of the unions, compensation related clauses, number of union and dynamics between the unions. To sun up, once company accomplish those conditions, it will elevate the successful rate of M&A.

With the industrial economy and changing times demand for talent in the organization of work, employee would not only want the salary, but further hope to cultivate the ability to meet their own interest with organizational development. There are more and more companies also starting to focus on employee career development and nurturing of talent management policies, such as personal development plans, job rotation, mentoring, competency model, succession planning, and so on are also promoting inter-enterprise. However, the implementation of the organization's policies and implementation have to cooperate with the staff's participation and recognition.

Knowledge of energy dissipation and relaxation in electron, spin, and lattice degrees of freedom is of fundamental importance from both a technological and scientific point of view. In this dissertation, the electronic and magnetization dynamics of photoexcited colloidal cobalt substituted iron oxide nanocrystals, CoxFe3-xO4, were investigated through transient absorption and pump-probe Faraday rotation measurements. In this dissertation, linearly polarized femtosecond optical pulses at 780 nm were used to excite the weak absorption originating from the intervalence charge transfer transition (IVCT) between Fe2+ and Fe3+ ions of Fe3O4 nanocrystals. The timescale and corresponding relaxation processes of electronic relaxation dynamics of the excited IVCT state were first discussed. Size effect on electronic relaxation dynamics in Fe3O4 nanocrystals is not distinct on the basis of result from this study. One interesting feature of electronic dynamics data of photoexcited Fe3O4 nanocrystals is the creation of coherent acoustic phonons. Information on lattice temperature was obtained by measuring the period of coherent acoustic phonon as a function of excitation fluence and fit into a simple model based on Lamb’s theory. Since optical control of the magnetization can be either through optical or heating mechanisms, quantitative estimation of degree of demagnetization caused by lattice temperature is made by using Langevin function. The result from such estimation indicates the effect of lattice temperature rise on magnetization is too small to significantly affect the magnetization of Fe3O4 nanocrystals. Magnetization dynamics were studied via pump-probe Faraday rotation measurements. Optical excitation with near-infrared pulse resulted in an ultrafast demagnetization in 100fs. The energy of the excited state then relaxed through spin-lattice relaxation (SLR). Effects of surface spin and chemical tuning on the SLR were investigated by comparing the magnetization recovery timescales of nanocrystal with different particle sizes and cobalt concentration respectively. The experimental result is explained by a simple model where interior and surface spins contributed to the spin-lattice relaxation process differently. The observations suggest that spin-orbit coupling of the surface is stronger and less sensitive to stoichiometric variation than the interior spins of the nanocrystals.

In this dissertation, I present an approach for physical construction of large structures. The approach is based on the graph rotation system framework. I propose two kinds of physical structures to represent the shape of design models. I have developed techniques to generate developable panels from any input polygonal mesh, which can be easily assembled to get the shape of the input polygonal mesh. The first structure is called plain woven structures. I have developed the ?projection method? to convert mathematical weaving cycles on any given polygonal mesh to developable strip panels. The width of weaving strips varies so that the surface of the input model can be covered almost completely. When these strip panels are assembled together, resulting shape resembles to a weaving in 3-space. The second structure is called band decomposition structures. I have developed a method to convert any given polygonal mesh into star-like developable elements, which we call vertex panels. Assembling vertex panels results in band decomposition structures. These band decomposition structures correspond to 2D-thickening of graphs embedded on surfaces. These band decompositions are contractible to their original graph. In a 2D-thickening, each vertex thickens to a polygon and each edge thickens to a band. Within the resulting band decomposition, each polygon corresponds to a vertex and each band corresponds to an edge that connects two vertex polygons. Since the approach is based on graph rotation system framework, the two structures do not have restrictions on design models. The input mesh can be of any genus. The faces in the input mesh can be triangle, quadrilateral, and any polygon. The advantages of this kind of large physical structure construction are low-cost material and prefabrication, easy assemble. Our techniques take the digital fabrication in a new direction and create complex and organic 3D forms. Along the theme of architecture this research has great implication for structure design and makes the more difficult task of construction techniques easier to understand for the fabricator. It has implications to the sculpture world as well as architecture.

Abstract¡G This thesis mainly implemented an RF transmitter with high efficiency and high linearity. A Cartesian to Polar transformation was implemented by CORDIC algorithm using FPGA. By replacing the envelope detector and limiter in traditional envelope elimination and restoration transmitter, this technique not only achieves more accurate modulation quality, but also becomes more suitable for single chip system. Applying the first order delta-sigma modulation and highly efficient switching-mode DC converter, the envelope signal was amplified highly efficiently. Due to the class-E power amplifier having good linear relation between output voltage and supply voltage, the polar modulation transmitter can achieve high efficiency and high linearity simultaneously. Furthermore, this thesis purposed a new transmitter with two-terminal time-varying modulation. The IQ modulated signal was fed to the input terminal of class-E amplifier, while the envelope signal was used to amplitude modulate the voltage supply terminal. With dynamic input power control, the conversion efficiency and linearity are independent of output power in the purposed architecture. From the experimental results, while transmitting a QPSK-modulated CDMA2000 1x signal with 1.2288 Msps data rate, the transmitter achieve 48 % in drain efficiency, 47 dB in ACPR, and 6 % in EVM at the output power ranging from 10 to 22 dBm.

Detailed film cooling effectiveness distributions were measured on the stationary blade tip and on the leading edge region of a rotating blade using a Pressure Sensitive Paint technique. Air and nitrogen gas were used as the film cooling gases and the oxygen concentration distribution for each case was measured. The film cooling effectiveness information was obtained from the difference of the oxygen concentration between air and nitrogen gas cases by applying the mass transfer analogy. In the case of the stationary blade tip, plane tip and squealer tip blades were used while the film cooling holes were located (a) along the camber line on the tip or (b) along the span of the pressure side. The average blowing ratio of the cooling gas was controlled to be 0.5, 1.0, and 2.0. Tests were conducted in a five-bladed linear cascade with a blow down facility. The free stream Reynolds number, based on the axial chord length and the exit velocity, was 1,100,000 and the inlet and the exit Mach number were 0.25 and 0.59, respectively. Turbulence intensity level at the cascade inlet was 9.7%. All measurements were made at three different tip gap clearances of 1%, 1.5%, and 2.5% of blade span. Results show that the locations of the film cooling holes and the presence of squealer have significant effects on surface static pressure and film-cooling effectiveness. Same technique was applied to the rotating turbine blade leading edge region. Tests were conducted on the first stage rotor of a 3-stage axial turbine. The Reynolds number based on the axial chord length and the exit velocity was 200,000 and the total to exit pressure ratio was 1.12 for the first rotor. The effects of the rotational speed and the blowing ratio were studied. The rotational speed was controlled to be 2400, 2550, and 3000 rpm and the blowing ratio was 0.5, 1.0, and 2.0. Two different film cooling hole geometries were used; 2-row and 3-row film cooling holes. Results show that the rotational speed changes the directions of the coolant flows. Blowing ratio also changes the distributions of the coolant flows. The results of this study will be helpful in understanding the physical phenomena regarding the film injection and designing more efficient turbine blades.
