Unstable etching of Si(110) with potassium hydroxide
No full textWe present experimental data for the morphological evolution of Si(110) etched with potassium hydroxide. The observed results are interpreted using a continuum equation. The results reveal the presence of unstable etching which leads to the formation of a columnar structure on the surface. The early stage of the formation of this columnar structure can be explained by a linear theory. This instability is caused by anisotropic surface tension
Wavelet characterization of the submicron surface roughness of anisotropically etched silicon
No full textThe roughness of etched Si(1 10) surfaces in tetra-methyl ammonium hydroxide has been characterized using the wavelet transform formalism. Wavelet coefficients corresponding to the experimental surface profiles have been calculated and the roughness exponent has been derived using the scalegram method. Its value has been found to be 0.5

Describing multiple aspects of use situation: applications of Design Information Framework (DIF) to scenario development
No full textScenarios have been broadly used to describe the context of a user's experience with products. Even though multiple aspects of user experience may be embedded in scenarios, they are not generally incorporated in a structured way. This research intends to develop methods of constructing scenarios by integrating multiple aspects of use situations with a coherent and accurate structure for evaluation. We introduce Design Information Framework (DIF) as a mechanism to accommodate multiple viewpoints and to represent them for effective management of design information. This research addresses the incorporation of this framework in a structured form of scenario generation to facilitate design problem identification and analysis from holistic viewpoints.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
