In the study described in this paper, the major components of an electronic performance support system are described and the use of scaffolding techniques within such electronic environments is explored. Four different types of scaffolding are discussed: conceptual (supportive) scaffolding, metacognitive (reflective) scaffolding, procedural scaffolding and strategic-intrinsic scaffolding. The paper also discusses some of the challenges that developers face when they plan to include scaffolding techniques as part of an electronic performance support system.

Parameter extraction and image enhancement for catadioptric omnidirectional cameras Baştanlar, Yalın; Çetin, Yasemin; Department of Information Systems (2005) In this thesis, catadioptric omnidirectional imaging systems are analyzed in detail. Omnidirectional image (ODI) formation characteristics of different camera-mirror configurations are examined and geometrical relations for panoramic and perspective image generation with common mirror types are summarized. A method is developed to determine the unknown parameters of a hyperboloidal-mirrored system using the world coordinates of a set of points and their corresponding image points on the ODI. A linear relati...
Wireless Sensing in Complex Electromagnetic Media: Construction Materials and Structural Monitoring Ozbey, Burak; DEMİR, Hilmi Volkan; Kurç, Özgür; ERTÜRK, VAKUR BEHÇET; ALTINTAŞ, AYHAN (2015-10-01) In this paper, wireless sensing in the presence of complex electromagnetic media created by combinations of reinforcing bars and concrete is investigated. The wireless displacement sensing system, primarily designed for use in structural health monitoring (SHM), is composed of a comb-like nested split-ring resonator (NSRR) probe and a transceiver antenna. Although each complex medium scenario is predicted to have a detrimental effect on sensing in principle, it is demonstrated that the proposed sensor geome...
Photoluminescence specroscopy of CdS and GaSe Seyhan, Ayşe; Turan, Raşit; Department of Physics (2003) With the use of photoluminescence (PL) spectroscopy one can able to get a great deal of information about electronic structure and optical processes in semiconductors by the aid of optical characterization. Among various compound semiconductors, Cadmium Sulfide (CdS) and Gallium Selenide (GaSe) are interesting materials for their PL emissions. Particularly, due to its strong anisotropy, investigation of GaSe necessitates new experimental approaches to the PL technique. We have designed, fabricated and used ...
Multivariate analysis: An essential for studying complex glasses Sargın, Irmak; McCloy, John S.; Beckman, Scott P. (2022-12-01) Understanding the impact of individual compositional components on the devitrification of complex multicomponent glasses, for example, 10-50+ oxides, typically requires numerous studies to examine each component's impact. Here we apply exploratory data analysis (EDA) to a heterogeneous data set of silicate glasses to determine the cations' individual and interacting effects on the crystallization of nepheline (nominally NaAlSiO4). Our data consisted of 795 simulated high-level nuclear waste glasses composed...
Cramer Rao bounds and instrument optimization for slitless spectroscopy Öktem, Sevinç Figen; Davila, Joseph (2013-05-26) Spectroscopy is a fundamental diagnostic technique in physical sciences with widespread application. Multi-order slitless imaging spectroscopy has been recently proposed to overcome the limitations of traditional spectrographs, in particular their small instantaneous field of view. Since an inversion is required to infer the physical parameters of interest from slitless spectroscopic measurements, a rigorous theory is essential for quantitative characterization of their performance. In this paper we develop...
