Museums are sites of contested meaning that bring together artifacts of the other with the sense-making practices of patrons. The Dead Sea Scrolls exhibit in Charlotte, North Carolina exemplifies a similar struggle as patrons negotiate between appeals to the authority of science and appeals to the authority of the Bible. Our analysis demonstrates that religion-rather than class struggle-permeates the encoding and decoding practices there. This struggle is exacerbated in part because of the religious nature of the artifacts on display;and also because when read as a text, the site's latent discourse reinforces the collective belief among many Evangelical Christians in the accuracy of the Bible. Furthermore, the exhibit's public relations campaign, its layout and design, and the predominantly Christian background of its guests coalesce to amplify a sense of the numinous.

We proposed and demonstrated a novel time domain spectral phase encoding/decoding scheme by time domain stretching and high speed phase modulating short optical pulses. 16 chips, 40 GHz/chip optical codes have been generated and recognized successfully using long chirped fibre Bragg grating (LCFBG) as dispersive components, respectively. Transmission experiments have been carried out successfully with 2.5 Gbps over up to 50 km SMF.

Rosen's modelling relations constitute a conceptual schema for the understanding of the bidirectional process of correspondence between natural systems and formal symbolic systems. The notion of formal systems used in this study refers to information structures constructed as algebraic rings of observable attributes of natural systems, in which the notion of observable signifies a physical attribute that, in principle, can be measured. Due to the fact that modelling relations are bidirectional by construction, they admit a precise categorical formulation in terms of the category-theoretic syntactic language of adjoint functors, representing the inverse processes of information encoding/decoding via adjunctions. As an application, we construct a topological modelling schema of complex systems. The crucial distinguishing requirement between simple and complex systems in this schema is reflected with respect to their rings of observables by the property of global commutativity. The global information structure representing the behaviour of a complex system is modelled functorially in terms of its spectrum functor. An exact modelling relation is obtained by means of a complex encoding/decoding adjunction restricted to an equivalence between the category of complex information structures and the category of sheaves over a base category of partial or local information carriers equipped with an appropriate topology.

This paper presents customer participating 3D garment design methods for mass personalization. Complex fashion design is separated into garment surface modeling, pattern designing and texture mapping. Based on the modularization of the garment, we propose a component option sheet to describe the Garment surface Style (GS). Customers can choose components flexibly to construct a basic GS fast. Individual GS can be further modeled by editing the contour curves. Thus, we encode contour curves to save GS information and construct a GS library. The user can drag a favorite GS onto a 3D mannequin model and recover it by decoding the contour curves as a prototype for individual surface design. The users can also draw or drag style curves freely on a 3D triangular garment surface to design individual 3D pattern styles. Total or partial style curves encoding/decoding methods are proposed to store the 3D Pattern Style (PS), and to form a library. Customers can also choose a favorite PS and decode them on another garment surface as a prototype for individual pattern design. Through flexible choices from the garment component library, GS library, PS library, and simply dragging or drawing of contour curves and style curves, customers can easily and conveniently participate in 3D garment design for mass personalization.

We propose a novel reconfigurable optical en/decoder to generate and recognize two-dimensional (2-D) optical codes for coherent optical-code-division- multiple-access (OCDMA) application. The proposed device is based on cascaded coupled micro-ring reflectors, which can enable simultaneous tuning of the fast wavelength hopping and spectral phase encoding code patterns. The coding performance is verified by simulation.
