Assessment of Self-Archiving in Institutional Repositories: Depositorship and Full-Text Availability
No full textThis research evaluates the success of open access self-archiving in several well-known institutional repositories. Two assessment factors have been applied to examine the current practice of self-archiving: depositorship and the availability of full text. This research discovers that the rate of author self-archiving is low and that the majority of documents have been deposited by a librarian or administrative staff. Similarly, the rate of full-text availability is relatively low, except for Australian repositories. By identifying different practices of self-archiving, repository managers can create new strategies for the operation of their repositories and the development of archiving policies

실리콘 CVD에서 charge에 관련된 증착 현상
No full text학위논문(박사) - 한국과학기술원 : 재료공학과, 1998.8, [ xiii, 135 p. ]This thesis consists of three major parts; ``the effect of gas phase reaction on the roughness of silicon films in HF-CVD``, ``morphological evolution of silicon films induced by charges in CVD``, and ``new approach to SSD and SENTAXY in CVD``. All of them are closely related to ``charge-related deposition phenomena in silicon CVD``.
Chapter III dealt with ``the effect of gas phase reaction on the roughness of silicon films in HF-CVD``, where the charges were introduced by the thermoemission effect of the hot-filament. For the system, combinations of the amount of the electron emission and the supersaturation ratio affected the deposition rate, the current, and finally the roughness of silicon film in a different way. Currents of 0.2 ~ 5 μwere measured in the hot filament CVD chamber for deposition of silicon. In such a highly ionizing atmosphere with the appreciable supersaturation for precipitation of silicon, it is highly probable that the charged clusters should be formed in the gas phase by ion-induced or photo-induced nucleation. The predicted nanometer silicon clusters were observed by TEM on a carbon membrane, which was placed in the hot-filament CVD chamber. The clusters for the filament temperatures of 1800℃ and 1600℃ were ~ 2 nm and 5 ~ 7 nm, respectively. Moreover, there was a linear relationship between the cluster sizes and the RMS roughness. These results, which could be explained by classical nucleation theory and Coulomb repulsion effect, leads to the following conclusion: higher electron emission enhances the gas phase nucleation with the help of the ionization process, but it prevents the charged clusters from growing to the large size, so smoother film can be deposited. Furthermore, at the constant electron emission, the gas phase with higher supersaturation ratio has lower nucleation energy barrier, and makes many small charged clusters by the ion-induced heterogeneous nucleation, thus producing smoother surface.

Transparent thin-film transistors with zinc oxide semiconductor fabricated by reactive sputtering using metallic zinc target
No full textWe have investigated transparent thin-film transistors (TTFTs) with active channel of zinc oxide (ZnO) films, reactively grown by RF magnetron sputtering using metallic zinc target. According to the ratio of oxygen to the total gas (O-2/(O-2+Ar)), inicrostructures of the films changed drastically, and especially, ZnO Films formed at 20% of O-2 had good crystallinity with larger grains. ZnO films showed above 84% transparency in the wavelength range from 400 nm to 750 nm. Our bottom-gate ZnO-TTFTs showed n-type character with field-effect mobility of about 1.5 cm(2/)Vs, an on/off ratio> 10(6), Subthreshold swing of 1.1 V/decade, and threshold voltage of 15.9 V, after annealing at 250 degrees C for 30 min in O-2 ambient.

Interactive multimedia Learning science with puzzles / Cheong Ngee Sun
No full textEducational innovation occurs in many different ways. One approach use computer technologies to enhance the learning environment. Besides, computer assisted-learning can reduce the anxiety of students and turn out to be a positive side of learning (Gates, 1997). Children are our future leaders in the coming generation. Hence, Interactive Multimedia Learning Science with Puzzles is an interactive educational learning science with puzzles in English meant for children aged 6 to 9 years old. It
comprises of an interesting storytelling with puzzles games, suitable for lower primary school (primary 1-3) for Malaysian children. It is a web based multimedia
learning - teaching and can be beneficial teaching tool for parents and teachers in educating the young children because the teaching will follow closely to the KBSR Science syllabus. Interactive Multimedia Learning Science with Puzzles is developed to promote education in a more fun, easier and relaxing environment for children to learn science. Thus, it will eventually develop their interest in learning new thing. This package comprises storytelling, quiz puzzles, & puzzles games with cartoon

C-60-mediated self-assembly of gold nanoparticles at the liquid/liquid interface
No full textC-60-mediated self-assembly of gold nanoparticles at the liquid/liquid interface in the form of a stable nanocomposite film is repoted. The metallic luster of the interfacial film results from the electronic coupling of Au nanoparticles, suggesting the formation of closely packed nanoparticle thin C films. The interfacial film of nanoparticles could be transferred to mica substrates and carbon-coated transmission electron microscopy (TEM) grids, and then studied by UV-vis, Raman spectroscopy and TEM.

Applying the NISO Metasearch Initiative Scheme to Enhance E-Resources Management at Rutgers University Library
No full textThis paper discusses problems in the management of library e-resources and attempts to identify potential solutions to the problems. By describing an e-resources enhancement project taken by Rutgers University Libraries, this paper points to the importance of providing contextually-rich metadata and reorganizing the accessibility of e-resources on a library’s website. It introduces how this Rutgers project adopted the National Information Standards Organization Metasearch Initiative to support the identification of appropriate e-collections for metaseaching. The outcomes of the project have facilitated a dynamic display of relevant e-resources to library users as an effective way of automatic access to library e-collections.Peer reviewe
A Metadata Manager's Role in Collaborative Projects: The Rutgers University Libraries Experience
No full textPurpose – This article discusses the roles and responsibilities of a metadata manager in collaborative digital projects.
Methodology – It describes the general requirements for metadata management, and introduces some scenarios in the practices of digital projects by the Rutgers University Libraries to support the generalized definition. A workflow of metadata management is illustrated.
Practical implications – With an explicit definition of the roles and responsibilities of the metadata manager, many other digital libraries that need to develop a new or optimize the existing workflow may find the Rutgers experience useful as reference.
Originality – Very few articles have explored this topic although the functions of metadata in the development of digital projects have been talked extensively.Peer reviewe
