The BaTiO3 sample was made by dry pressure, it was artificial spread nickel paste on BaTiO3, and it was simulated multilayer ceramic capacitors (MLCC¡¦s) to make a sandwich structure with BaTiO3-Ni-BaTiO3 by sintered in YAGEO¡¦s laboratories. The samples have been thoroughly analysis for the interface between BaTiO3 dielectric and Ni electrode or NiO oxide, by X-ray diffractometry, scanning electron microscopy, and transmission electron microscopy. The interface between BaTiO3 and Ni has not orientation relationship as determined by selected area diffraction and it¡¦s not had dislocations in interface by two- beam image. The NiO oxide as determined by XRD and TEM, because of the thermodynamic potential of the Ni/NiO equilibrium was produced. The array of dislocations of Burgers vector is 1/2[ 10] in the interface, and Burgers vectors are 1/2[00 ], [ 1 ] as determined by high resolution images and Fast Fourier Transform simulation. Misfit dislocations along the interface occur to accommodate the lattice mismatch.

Abstract The thesis comprises two different IC design projects, which are briefly introduced as follows. The first part is the NIC (Network Interface Controller) design. The NIC implements all of the Media Access Control (MAC) layer functions for transmission and reception of packets in accordance with the IEEE 802.3 standard. The design is compatible with CSMA/CD type Local Area Network, i.e, 100/10 Mbps Ethernet. The second part is a post-amplifier for a 16Mbps infrared transceiver module. We presents a design of the post-amplifier to convert the pre-amplifier output into digital pulses such that the baseband digital codec can further translate the pulses into the format of IrDA protocols. The design of the amplifier is aimed at the VFIR (very fast infrared) which is supposed to provide a 16 Mbps data transmission rate. The circuit design is carried out by TSMC 0.35 um 1P4M CMOS technology. The simulations results of the design meet the required specification of IrDA VFIR.

This dissertation is a theoretical investigation of the thesis of Minimalist Interfaces, namely, that syntax-external linguistic interfaces that interact with the core syntactic computation and language-independent sound and concept systems play a more critical role in manipulating syntactic objects to make them legible to those systems than is currently assumed in the recent minimalist inquiry. The core theme of this thesis lies in the idea that syntax is not entirely crash-proof but could make a variety of derivational mistakes; phonological and semantic linguistic interfaces conduct a handful of independent domain-specific operations to attempt to legitimize illicit syntactic objects, if any, for the purposes of legibility at the language-external sound and concept systems. Evidence is provided that the syntax-external components use whatever resources they can to repair certain "imperfections" created by syntax but only within the range of options made available by the universal principles of syntax in tandem with the language-specific parameter values. This dissertation explores some of the ramifications and empirical consequences of this thesis based on the comprehensive description of a sizable portion of the grammar of Indonesian and Javanese collected by my fieldwork with three native Indonesian and Javanese consultants. Phenomena discussed here include the distribution of active voice morphology, P-stranding under sluicing, the denotation and morphosyntax of bare nominals, wh-in-situ questions, and reduplication asymmetries between nominal and verbal derivational affixes. These diverse ranges of phenomena in the two languages are analyzed in depth to provide converging evidence that the thesis of minimalist interface as defined above yields a deep understanding of the way the syntax interacts with the language-dependent interfaces responsible for phonological and semantic interpretation. The investigation conducted here, necessitates serious reconsideration of the commonly held view of linguistic interfaces as passive, merely ornamental components of natural language grammar ruled by the universal law of syntax.

Lacome is a multi-user cross-platform system that supports collaboration in a shared large screen display environment. Lacome allows users to share their desktops or application windows using any standard VNC server. It supports multi-user concurrent interaction on the public shared display as well as input redirection so users can control each other's applications. La-come supports separate types of interaction through a Lacome client for window management tasks on the shared display(move, resize, iconify, de-iconify) and for application interactions through the VNC servers. The system architecture provides for Publishers that share information and Navigators that access information. A Lacome client can have either or both, and can initiate additional Publishers on other VNC servers that may not be Lacome clients. Explicit access control policies on both the server side the client side provide a flexible framework for sharing. The architecture builds on standard cross-platform components such as VNC and JRE. Interaction techniques used in the window manager ensure simple and transparent multi-user interactions for managing the shared display space. We illustrate the design and implementation of Lacome and provide insights from initial user experience with the system.

Services that once required human interaction are now completed with the click of a few buttons. In general, this allows for a more streamlined process for activities such as sending messages (email or text messages), filing taxes, or even shopping for groceries. In terms of searching for hotels and travel accommodations however, this process has not proven to be the most effective as the speed and efficiency is hindered by the interface through which this information is available. Choosing a travel specific site, filling in the required fields, combing through results for the desired specifications, and then possibly repeating the process elsewhere, does not provide the ability for the user to express the entirety of their preferences for the accommodation and is therefore not an effective method for searching. Natural language search provides a more accessible and intuitive interface for accommodation searching. Instead of specifying fields that may not encompass the the entirety of the desired search, the user is able to express all of the aspects in a single, natural language, search. In this project, we propose a natural language search interface for accommodations such as hotels, hostels, or apartments. Data acquired through Amazon Mechanical Turk is used to create a system for extracting various accommodation fields. Zilyo and Expedia APIs are then queried for real-time accommodation listings. These results are then adjusted based on the specifics of the search that were not included in the original query. A natural language search of this kind is not only more accessible on the consumer end, but provides data that pertains directly to the the entirety of the intended search.

The interfacial structure of Co/Cu multilayers deposited under energetic ion bombardment has been investigated using X-ray reflectivity techniques. An ionassisted deposition system, based on unbalanced magnetron sputtering principles, has been developed in order to provide a method for the independent control of ion flux and energy. Using this system ion current densities measured at the substrate could be varied from ~30 µAcm2 to ~100 µAcm2 and average ion energies of ~50-200 eV could be selected. It was therefore possible to prepare Co/Cu multilayers under a variety of ion bombardment conditions and thus study the effect of this energetic particle bombardment on the evolution of interface structure. Samples were characterised by measuring the specular and diffuse X-ray reflectivity, using anomalous scattering effects to enhance the contrast between the cobalt and copper layers. Quantitative analysis of the specular reflection revealed the existence of variations of the interface roughness in multilayers deposited under ~200 eV ion bombardment, such that the interfaces became smoother towards the free surface. Films deposited with the highest available levels of ion flux were found to display the greatest interface smoothing effect. However, no such variation was observed when ion energies of ~50 eV were applied, although differences in the large lateral scale correlated roughness were observed between ~50 eV ion-assisted and non ion-assisted samples. The sensitivity of the interface structure to energetic bombardment during growth is thus demonstrated and the results are discussed in terms of resputtering and ion bombardment induced reordering of the growing surface. It is shown that these effects can be exploited to obtain multilayers with atomically smooth interfaces.

This thesis examines turbulent diffusion processes in rectangular and compound open channels, with particular attention to the effect of secondary flow and the relationship between eddy viscosity and eddy diffusivity. Three dimensional velocities and concentration were measured using 3 component Laser Doppler Velocimetry (LDV) combined with Laser Induced Fluorescence (LIF) from three laboratory flumes: one rectangular simple channel and a deep and a shallow compound channel.
