Engineering in the Field of Vision of Philosophy

Strategic Study of CAE 2008, Volume 10, Issue 3,   Pages 4-8

Abstract:

Through a study on materialist conception of history, it is indicated that engineering is a basic practical activity during humanity existence and development, and always a direct productivity at different historical periods. The engineering activity appeared before science activity. It is also believed that the knowledge and activity which relates to nature should be divided into three components of science, technology and engineering.The main characters of the science activity are "exploration"  and "discovery" , the main characters of the technology activity are "invention"  and " innovation" , and the main characters of the engineering activity are "integration"  and " construction" . From a point of view of modern knowledge, a related knowledge chain (knowledge network) exists among science-technology-engineering-industry. The relationship between engineering and industry is more direct and closes.The engineering is a practical activity of humanity for maintaining existence, multiplication and development, and constructing "homeland"  and "living"  well, and is also an embodiment of human wisdom and seeked "ideal" . From a point of view of philosophy, the result of the engineering activity usually embodies in constructing a new existence, i.e. an integrator of optimized construction under a certain boundary condition. Engineering integration contains various technical element integration, and also contains optimization-integration of technical element and basic elements of economics, society and management under a certain condition.Under a condition of new century, engineering is an important field of innovation activity, should be a new field of philosophy consideration. The transcendence of philosophy and engineering exists various "intermingling"  and "merging" . Therefore, engineering needs philosophy, and philosophy needs to face engineering. An interaction of engineering and philosophy is a feature raising in the Chinese engineering philosophy.

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 1,   Pages 113-122 doi: 10.1631/FITEE.2000407

Abstract: We describe a method of extraction for high-speed high-brightness targets based on a pulse array image sensor (PAIS). PAIS is a with pixels triggered by light; it can convert light into a series of pulse intervals. This method can obtain from pulse data directly by accumulating continuous pulses. The triggered points can be used to filter redundant data when the target is brighter than the background. The method takes full advantage of the rapid response of PAIS to high-brightness targets. We applied this method to extract the of high-speed turntables with different background brightness, with the sensor model and actual data, respectively. Under the sampling condition of 2×10 frames/s, the could be extracted from a high-speed turntable rotating at 1000 r/min. More than 90% of redundant points could be filtered by our method. Experimental results showed that the extraction algorithm based on pulse data can extract the information of high-brightness objects efficiently without the need to reconstruct images.
