Hong Kong (short films)
No full textCOMING-OF-AGE OF HONG KONG\u27S INDEPENDENT SHORT FILMS An interesting phenomenon as a result of Hong Kong\u27s handover to China in 1997 was a profusion of innovative short films by young directors who worked mostly in video. Their "shoot-on-the-run" films, made on shoestring budgets, documented the anxieties and opinions of the ordinary Hong Konger about the colony\u27s return to the mainland. Ten of these shorts, ranging from 5 to 30 minutes, were shown at the 22nd Hong Kong International Film Festival (HKIFF) in 1998 under the title \u27Digital Biography of Hong Kong, Progams I & II\u27. The \u27digital diaries\u27, as these videos were called, were commissioned by the Japanese producer Mio Hani and Stella Sze. Program I offered Howard Cheng\u27s fragmented, two-part, experimental video, The Daily Mood of Final Certainty or The House of August, about 5 characters.

Genetic algorithms with immigrants and memory schemes for dynamic shortest path routing problems in mobile ad hoc networks
No full textThis article is posted here with permission of IEEE - Copyright @ 2010 IEEEIn recent years, the static shortest path (SP) problem has been well addressed using intelligent optimization techniques, e.g., artificial neural networks, genetic algorithms (GAs), particle swarm optimization, etc. However, with the advancement in wireless communications, more and more mobile wireless networks appear, e.g., mobile networks [mobile ad hoc networks (MANETs)], wireless sensor networks, etc. One of the most important characteristics in mobile wireless networks is the topology dynamics, i.e., the network topology changes over time due to energy conservation or node mobility. Therefore, the SP routing problem in MANETs turns out to be a dynamic optimization problem. In this paper, we propose to use GAs with immigrants and memory schemes to solve the dynamic SP routing problem in MANETs. We consider MANETs as target systems because they represent new-generation wireless networks. The experimental results show that these immigrants and memory-based GAs can quickly adapt to environmental changes (i.e., the network topology changes) and produce high-quality solutions after each change.This work was supported by the Engineering

Preparation of sub-micron PZT particles with the sol-gel technique
No full textThis paper describes the production of Pb1.0Zr0.9Ti0.1 ceramic powder, by using metal organic precursors as starting materials. In this study polyvinylpyrrolidone, PVP, was used to create a PZT–PVP sol and then also added as a secondary stage to control the particle size of the powder.
Two different sol–gel routes were used to create PZT powder. Both routes gave similar primary particle sizes in the range, 30–70 nm, but different agglomerate formations. Perovskite PZT powder was created with both routes

Angular super-resolution in X-ray projection radiography using deep neural network: Implementation on rotational angiography
No full textBackground: Rotational angiography acquires radiographs at multiple projection angles to demonstrate superimposed vasculature. However, this comes at the expense of the inherent risk of increased ionizing radiation. In this paper, building upon a successful deep learning model, we developed a novel technique to super-resolve the radiography at different projection angles to reduce the actual projections needed for a diagnosable radiographic procedure. Methods: Ten models were trained for different levels of angular super-resolution (ASR), denoted as ASRN, where for every N+2 frames, the first and the last frames were submitted as inputs to super-resolve the intermediate N frames. Results: The results show that large arterial structures were well preserved in all ASR levels. Small arteries were adequately visualized in lower ASR levels but progressively blurred out in higher ASR levels. Noninferiority of image quality was demonstrated in ASR1–4 (99.75% confidence intervals: −0.16–0.03, −0.19–0.04, −0.17–0.01, −0.15–0.05 respectively). Conclusions: ASR technique is capable of super-resolving rotational angiographic frames at intermediate projection angles
