Diamond-Like Carbon ¡]DLC¡^films were successfully deposited on the ITO substrate by electrodeposition technique. This method has several advantages in terms of low cost, rapid growth rates and simple setup. Electrodeposition of DLC thin film was carried out at low DC potential by using a mixture of acetic acid and DI water as electrolyte. The Raman spectra showed two peaks located at 1350cm-1 and 1580cm-1, which were the characterized peaks for DLC films deposited on ITO substrates. By varying the experimental parameters such as the deposited DC potential, distance of electrodes, and the concentrations of solution, the growth mechanism of deposition process was investigated, and the best quality of DLC films was also achieved. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) were used to make insight into accurately the surface morphology of DLC films related to deposited parameters In addition, according to the experimental results, it indicates that the quality of the DLC film was improved as deposited at higher DC voltage. Finally, to demonstrate the effect of annealing on the interfacial characteristics the C-V and G-V curves of MIS structures are the further works.

As information technology advances, not only affects the IT staff in dealing with the application of information technology, and its role in the work are also consequential changes; even in the flexible non-governmental organizations, institutions, and its internal information units also deeply by the traction. Therefore, IT must change as information technology, and fully upgrade the professional knowledge and information processing techniques capability of making their own role to play. In this study, the central government authority of the Kaohsiung National Tax Administration(NTAK) information platform migration, for example, explore the changing role of the NTAK case of information officers; We find that although the IT staff in particular portfolio unchanged, but actually with the National Tax the transfer of information arising from the work platform, the large changes in the content, and requirements for the role of IT staff, but also with the transfer of tax information platform of change vary. To explain in the following two points: 1. The IT sector through tax information platform for transfer of changes arising from the previous information system developers and maintainers technical support for users who change and strategy role. 2. The IT department staff within the information platform for transfer after tax arising from changes in hardware is responsible for the information of human grade or transferred to the IT professional officers with information, application system maintenance are transferred to the tax Grade or have a professional staff for the tax business, the role of changes in each other's work, have the expertise required is different.

Diamond-Like carbon (DLC) films has a lot of advantages, such as high hardness, high thermal conductivity, low expansion coefficient, low friction coefficient, high chemical stability, high impedance. These properties make the DLC films suitable for becoming an insulator in metal insulator semiconductor structure. In this study, DLC films were deposited by electro-deposition technique onto silicon (Si) substrates, in which a mixture of acetic acid and water is used as the electrolyte. The structure of the DLC films is characterized by Raman Spectroscopy. The thermal evaporation technique was used to deposit an aluminum films on the DLC/Si-substrates, to make it as the structure of metal-insulator semiconductor (MIS), and the electrical properties of the MIS were measured by semiconductor parameter analyzer. DLC films were deposited by varying the parameters of electro-deposition process included mainly as the concentration of solution, the spacing between electrode and silicon substrate, deposition temperature, and the applied voltages. The properties and film growth of DLC attributed to the effect of parameters were described in detail. Finally, an electro-deposition model is obtained to describe the growth mechanism of electro-deposition of DLC film.

Diamond-Like Carbon (DLC) films have been deposited on different substrates such as p-type Silicon substrate and ITO glass substrate. DLC thin film was electrodeposited at low DC potential using a mixture of acetic acid and DI water. The DLC film deposition parameters include DC potential, deposited temperature, solution concentration, are used to study the characteristics of DLC film in detail. In addition, the growth mechanism of deposition process is also discussed. We are to improve and to solve the edge induced effect on inhomogeneous film thickness during electrodeposition. The Raman spectra shows two peaks located near 1358cm-1 and 1580cm-1, assigned as the characteristics peaks of DLC films. That is an evidence for DLC film deposited successfully on ITO glass and Silicon substrates. Scanning electron microscopy (SEM) can make insight into accurately the surface morphology and uniformity of DLC films so as used to grow the best quality of DLC films. Finally, N-type of doped DLC films has been achieved on p-type silicon substrate to form the hetero-junction diode, and the intrinsic DLC film acts as the insulating layer for MIS structure is also obtained. The electrical characteristics of hetero-junction diode and MIS devices are presented and to be discussed in future.

Neurosurgical retraction is a procedure that involves displacing brain tissue (i.e., to expose cancerous lesions). Current tools for retraction are mostly made of stainless steel and create localized regions of pressure. These tool-tissue interactions can be harmful and lead to postoperative complications. Research on soft robots is rapidly expanding due to their ability to safely interact with human tissue. Using principles of morphological computation, origami-inspired folding patterns have been developed to control the behavior of soft robots. However, for delicate brain tissue-tool interaction, greater control through the integration of soft sensing is required by surgeons. This work presents a pressure-actuated, origami-inspired soft robot with integrated sensing for measuring force during neurosurgical retraction procedures. The robot employs a circular Miura-origami (Miura-ori) pattern, creating well-defined contraction and expansion ratios. To embed a sensing modality in the robot, individual origami unit cells are modified to become flexible capacitors. These flexible Origami Sensing Modules (OSMs) change in capacitance when force is applied due to the displacement of capacitive plates. Surgeons can therefore monitor the procedure to ensure that dangerous levels of force are not exceeded. The OSM is fabricated using a layering technique that embeds a fluidic stiffening actuator within an elastomer dielectric. Thin copper films, which form the capacitive plates, sandwich this dielectric layer. Three OSMs, connected in series, are integrated into the circular Miura-ori pattern at evenly spaced locations. The force range and sensitivity of the OSMs are analyzed through force and motion characterization experiments which give an indication of the capacitive behavior during force application and actuation of the robot. Finally, an in-vitro setup was developed to model the retraction process in the brain and demonstrate the robot’s ability to retract brain tissue and sense the distributed forces. The development of this sensing mechanism allows for both monitoring and controlling the pressure on brain tissue during robotic retraction, demonstrating the potential of soft robots in neurosurgery. / 2025-08-29T00:00:00Z

Thesis advisor: Jeremy D. Shakun / Arctic permafrost contains a substantial stock of carbon that could be released to the atmosphere as CH4 and CO2 upon thawing, making it a potentially powerful amplifier of future warming. The sensitivity of permafrost to climate change is uncertain, however, and occurs on time scales longer than those captured by the instrumental record. Speleothems – cave precipitates deposited from flowing or dripping water – in currently frozen regions record past episodes of thaw, which can be used to assess the response of permafrost to long-term warmth. Here, we present 90 uranium-thorium ages on speleothems from across the North American Arctic, sub-Arctic and northern alpine regions to reconstruct a 600-kyr permafrost history. Widespread speleothem growth supports an episode of extensive permafrost thaw during the Marine Isotope Stage 11 interglacial about 400 ka, when global temperature was only slightly warmer than pre-industrial conditions. Additional growth is evident during MIS 13, curiously, a smaller magnitude interglacial. Ice-core records of atmospheric greenhouse gases do not show elevated concentrations at these times, perhaps suggesting that the permafrost carbon pool was smaller than today or released gradually enough to be buffered by other reservoirs. / Thesis (MS) — Boston College, 2017. / Submitted to: Boston College.

To this day, the field of the information systems (IS) research, belonging to an intact field, has evolved over thirty years. Due to the rapid development of information technology, the information systems have not only influenced enterprises and personal life but also impacted on IS research field. The development of Taiwan IS research community though lags behind that of foreign countries. During the past decade, the proportion of IS research community in Taiwan has increased tremendously and the IS research community has played an important role in local information systems and accumulation of relevant knowledge about business electronics as well. However, when the researchers want to propose their research results, they will encounter several difficulties, for instance: they do not fully understand the ecology of IS research, and it is not easy for them to keep up with the trends of future development of the IS, so they just follow the trends and cannot create them by themselves. In order to transform local IS researches into becoming mainstream of international academic studies, we have to gain insights into IS ecology and diversity of IS studies. Many years earlier, there had been numerous studies about IS research community, but many of them focused on the classifications of IS studies. They did not have concise and accurate predictions, so we try to use rigid ecological modeling method to investigate IS research community in our research. This research will include the foundings, mortality, evolution, density dependence, key species of different IS research issues, and main internal and external environmental forces of IS research diversity as well in order to build the ecological model of IS studies. We hope to not only get hold of evolution and trends of IS studies but also enhance the qualities of IS studies and applications of information systems in Taiwan through this ecological model.
