Experimental observation of solidification of undercooled single phase alloys

引用

中国有色金属学会会刊：英文版 2000年第6期10卷 705-708页

作者：李金富杨根仓张雪萍周尧和 Shanghai Jiao Tong Univ Sch Mat Sci & Engn Shanghai 200030 Peoples R China Northwestern Polytech Univ State Key Lab Solidificat Proc Xian 710072 Peoples R China

The solidification process of undercooled Cu 70 Ni 30 alloy melt in a cylindrical crucible was investigated by high speed cinematography. In the experiment, nucleation location was controlled at one end of the sample by means of artificial triggering. The results show that the equiaxed dendritic crystals obtained at low undercooling form in sequential solidification, rather than simultaneously in the entire sample, and the morphology of the recalescence front frequently changes with time. If increment of undercooling results in that the dendrite growth is controlled by thermal diffusion, the primary dendrite arms propagate parallel to each other in 〈100〉, and eventually directional solidification microstructure is obtained. At higher undercooling, dendrite growth is destabilized due to solidification contraction, and the microstructure develops into fine quasi spherical grains through recrystallization, however, the massive nucleation is not found.[

Computer Systems Science & Engineering 2022年第6期41卷 875-890页

The applications of information technology (IT) tools and techniqueshave, over the years, simplified complex problem solving procedures. But thepower of automation is inhibited by the technicality in manning advanced equipment. To this end, tools deliberately combating this inhibition and advancing technological growth are the Unmanned Aerial Vehicles (UAVs). UAVs are rapidlytaking over major industries such as logistics, security, and *** others, this is a very efficient way of carrying out missions unconventional to humans. An application area of this technology is the local film industrywhich is not producing quality movies primarily due to the lack of technicalknow-how in utilizing these systems. This study therefore aim to devise an autonomous object tracking UAV system that would eliminate the complex procedureinvolved in stabilizing an aerial camera (aerial bot) midair and promote the creation of quality aerial video shooting. The study adopted Unified Modeling Language (UML) tools in modeling the system’s functionality. The traditionalServer-Client model architecture was adopted. The OpenCV library employedproved highly efficient in aiding the tracking procedure. The system provided ausable web controller which provides easy interaction between the pilot and thedrone. Conclusively, investments in UAVs would enhance creation of quality graphic contents.

Poetry and Cinema

引用

Journal of Literature and Art Studies 2012年第4期2卷 480-482页

作者： Cedric VanEenoo Bangkok University Bangkok Thailand

Poetry can be seen as a means for communicating a message in a unique vision. The same can be applied to cinema. Literature precedes the making of a film in most cases. The preparation for a movie is written in much details, be it for stories, scenes, dialogues, storyboards, or technical descriptions. In that extend, words are the genesis of cinema. Poetry is a unique way to express one＇s point of view in a metaphoric way, far from common means of communicating a message. This purpose is the one of many a film director with daring, controversial, or highly personal ideas. The study will concentrate on the link of cinema with poetry based on the concept of rhymes and rhythms.

Anatomy of a Guerrilla Film : The Making of Radius 1

引用

2005年

作者： Kobler Helmut.

ISBN: (纸本)1592009107;1592009115

"Anatomy of a Guerrilla Film: The Making of RADIUS," does something that no other how-to filmmaking book does: it teaches filmmaking principles by taking readers through the process of making a real-world guerrilla film and then lets you watch the final film - included on an accompanying DVD - so readers can actually see the results of all the decisions, compromises, setbacks, and victories. First-time filmmaker and author Helmut Kobler believes that the best way to learn is by watching other people do something and then learning from their successes and mistakes. That philosophy is the concept behind this book. Written in clear, straightforward language for the first-time or beginning filmmaker, "Anatomy of a Guerrilla Film: The Making of RADIUS," serves as a case-study for new filmmakers, allowing them to see the lessons and principles presented in the book come to life in the actual film. From start to finish, every step and process that encompasses making an independent film is covered, including preproduction, production, post production, and marketing and distribution. Different approaches to each step and process are covered, not just the approach used by the author. Behind-the-scenes footage and commentary by the author on the included DVD clearly illustrate the steps making this book the most unique and hands-on guide to guerrilla filmmaking

Style of "the Pictorial Shakespeare"—— Auteur Theory Applying to Akira Kurosawa's Work

引用

Review of Educational Theory 2018年第4期1卷 137-140页

作者： Shindy Lan The University of Manchester Manchester M139PL UK

By investigating the cinematography and thematic concerns of Akira Kurosawa's work under the auteurist criteria, it can be argued that Kurosawa is an auteur whose work possesses three distinctive authorial signatures: the active involvement of nature, the strong sense of stage-performance, the editing on movement;and the consistent visual style has corresponding meaning concerning his personal experience and socio-historical circumstances.
