Analyzing the Capacity of Library and Information Science to Preserve Non-Fungible Tokens
Non-Fungible Tokens (NFTs) represent a new approach to ensuring authenticity of records, as well as being a medium that digital artists are flocking towards. Such a technology could prove to be incredibly useful in conducting work in the world of Library and Information Science. This research aimed to propose the beginnings of creating a set of best practices for the long-term preservation of NFTs, through interviewing LIS professionals who are experts in preservation. These interviews would attempt to garner insight on how NFTs could or couldn’t fit into pre-existing frameworks of preservation practices, and if not, how to adapt current practices to accommodate them. Due to a lack of responses, the approach of this paper shifted from primary research to a review article, still with the aim of trying to understand what accommodations may need to be made to preserve NFTs in the long term.Master of Science in Library Scienc
Pressure-distribution investigation of an N.A.C.A. 0009 airfoil with a 50-percent-chord plain flap and three tabs
Pressure-distribution tests of an N.A.C.A. 0009 airfoil with a 50-percent-chord plain flap and three plain tabs, having chords 10, 20, and 30 percent of the flap chord, were made in the N.A.C.A. 4- by 6- foot vertical tunnel. The tests supplied aerodynamic section data that may be applied to the design of horizontal and vertical tail surfaces. The results are presented as resultant-pressure diagrams for the airfoil with the flap and the 20-percent-chord tab. Plots are also given of increments of normal-force and hinge-moment coefficients for the airfoil, the flap, and the three tabs. The experimental results and values computed by analytical methods are in good agreement for small flap and tab deflections. The results of the tests indicated that the effectiveness of all three tab sizes in reducing flap hinge moments decreased with increasing flap deflection
Quantum well intermixing for the control of second order non-linear effects in GaAs/AIGaAs asymmetric quantum well waveguides
QW-intermixing was accomplished for several different multiple AQW structures using impurity-free vacancy disordering (IFVD). Unphase-matched second harmonic generation (SHG) experiments were subsequently performed with waveguides fabricated from as-grown and intermixed AQW material. No conclusive evidence was found for the existence of any AQW tensor components. This is consistent with recent calculations which predict, that for the particular AQW structures studied, the AQW non-linearities are negligible. Unphase-matched SHG was, however, observed which was attributable to the large bulk GaAs/AlGaAs d14 coefficient. Furthermore, d14 was reduced by 17% on intermixing. Since the quasi-phase-matching conversion efficiency is proportional to both the square of the magnitude of the non-linearity and the square of the modulation depth, a small but significant reduction in the large d14 coefficient such as this, could lead to useful conversion efficiencies.
Selective-area IFVD was achieved using hydrogen plasma processing to inhibit intermixing. Only partial suppression of the IFVD process was, however, achieved. The spatial resolution of the selective-area process was measured for two different MQW structures under different annealing conditions, and was found to be better than 2.2 m. The resolution of the IFVD process is therefore sufficiently good for the control of second order non-linear interactions in GaAs/AlGaAs MQW waveguides.
Periodically-intermixed waveguides were fabricated for quasi-phase-matching. These waveguides had measured losses ranging between 3.7 dB/cm and 18 dB/cm depending on the intermixing period. Phase-matching was not, however, observed in these devices. This may have been a consequence of one of several factors including, non-ideal laser tuning characteristics, the use of inaccurate intermixing periods, and a negligible modulation depth in d14. Further work is therefore necessary to establish why phase-matching was not achieved, and to improve the selective-area intermixing process. If these difficulties can be overcome and, in addition, an AQW structure can be designed with associated significant non-linearities, then SHG conversion efficiencies of several hundred %/Wcm2 may be possible
