Engineering Philosophy-based Reflections on Efficient Development of Shale Gas in China

The Shale Gas Revolution began to have a significant impact on global supply and demand of natural gas; also the price trend of natural gas has been greatly affected. This phenomenon raised concerns among natural gas producers and consumers. China has abundant shale gas resources, but the development scale is small while facing problems including weak exploration and evaluation basis, overlapping royalties, complex terrestrial environment, lack of technical practices and accumulation, inadequate management and regulatory mechanisms, etc. To overcome these challenges for large-scale shale gas development, we believe that shale gas development is not only a single technical problem, but a systematic engineering demanding multidisciplinary research that will be bound to spread to humans, nature, and society. Therefore, to ensure the healthy development of China’s shale gas, it is required to coordinate global and local relationships, engineering and community relations, as well as to break up the conflicts between engineering and nature, engineering and economy, along with engineering and society.     

Techniques for cancellation of interfering multiple reflections in terahertz time-domain measurements

Algorithms are described which allow a significant reduction of the effects of multiple pulses, which originate from pulse reflections within terahertz (THz) emitters. The algorithms are based on models for the pulse propagation inside the emitter. Model parameters can be estimated from a calibration experiment using a reference signal in the absence of a sample. The parameters once estimated for a particular emitter device, can then be used to suppress the effects of multiple pulses in all measurements performed with the same emitter. The application of this method is demonstrated in the investigation of a disc sample and in the investigation of a paint layer.     

Colour combination effects in experimental rooms*

This article deals with the way colours in a room affect each other through contrast effects and reflections. The study presented is based on the visual observations of the colour appearance of three inherent colours in a sequence of experimental situations. My point of departure was a yellow, blue, and red room. The room had distinctly different colour appearances of the same inherent colours when observed at different locations. The effects of both contrasts and reflections were evident. However, reflection effects seemed to dominate the situation. In a study of small experimental rooms, different combinations of the same three inherent colours were systematically tested. Comparisons were made to examine the differences in colour appearance between monochromatic rooms and multicoloured rooms with varying colour schemes. The illumination was kept stable. In the cases studied, it was obvious how the colours in the two‐coloured rooms became more alike or “neutralized each other.” The contrast strengthening between abutting areas on the same level had distinct significance for colour appearance and perception of space. However, not in such a way that the perceived colour differences became larger in the two‐coloured room than between each monochromatic rooms. © 1999 John Wiley & Sons, Inc.

Infinite reflection models for the visual arts

Artists do not always pursue photographic realism. The image abstraction and deformation of three-dimensional scenes are methods to communicate ideas. Images are the visual interpretation of real life or imaginary scenes. This paper describes the idea of an infinite reflection model in which synthetic objects to be rendered are surrounded by closed reflective surfaces. The closed mirror surfaces create the ‘feedback’ effect which deforms objects inside the reflective space. Lens distortion effects are achieved by surrounding infinitely reflective curved surfaces. This technique provides a new visual tool for artists and graphic designers.

Naive optics: Understanding the geometry of mirror reflections.

Paper-and-pencil tasks showed that many university students believed that when laterally approaching a mirror, they would see a reflection in the mirror before it was geometrically possible. Participants failed to adequately factor in the observer's location in the room. However, when asked about the behavior of a ray of light, participants knew about the law of reflection. No differences between psychology and physics students were detected, suggesting that the phenomenon is widespread and refractory to training. The findings were replicated with observers making judgments about image locations in a real room using a pretend mirror. Possible heuristics about mirror reflection that might explain the data are discussed. Naive optics is a promising venue to further knowledge of how observers understand basic laws of physics.
