: The photographer's awareness of the light in the scene is the key to good exposure, whether it is technically correct or an expression of creativity. The article deals with the role of light and its absence, shadow, in the field of photography. Several studies from history and the present are presented, linking the perception of light and its shadows from philosophical, artistic and technological points of view, illustrating the vastness and applicability of this field of research. Summarized studies and an eye tracking analysis of shadow perception support the author's claims about the role of light and shadow in the perception of Henri Cartier-Bresson's photographs. It is shown how shadows can reveal more to the viewer about the space surrounding the observed scene, function as individual objects, or even be used creatively to enhance the detection of focus within a photograph.

: With the progress of transportation, an increasing number of bridges are put into operation, and the assessment of bridge bearing capacity is considered a significant measure to ensure bridge safety. As a critical approach for structural monitoring, acoustic emission is widely used in engineering projects. Since the Kaiser effect is an important phenomenon in acoustic emission, it is necessary to explore the Kaiser effect of reinforced concrete structures and the determination method of the Kaiser point. In this thesis, four reinforced concrete simply supported beams were utilized for the graded loading experiment under bending loads. After accumulating acoustic emission parameters, Kaiser point was selected for preliminary evaluation. Taking Kaiser point as the midpoint, the appropriate interval was determined. According to the continuity criterion of acoustic emission signals and the quadratic fitting curve based on experimental data, the Kaiser point was corrected by following the average growth rate of acoustic emission parameters. These simply supported beams were classified into two groups. One group was used to explore the acoustic emission characteristics when the load was less than the historical maximum, while the other group was used to analyze changes in the Kaiser effect with increasing load. Finally, based on the results of the specimen inspection, the influence of initial damage on the Kaiser effect was analyzed. The research results alleviated the influence of human factors on the determination of the Kaiser point and can serve as the theoretical basis for damage monitoring based on the Kaiser effect and bearing capacity evaluation of reinforced concrete structures.

: To rapidly evaluate the seismic resilience of the bridges under construction, the construction stage seismic resilience evaluation method was proposed. Based on a case bridge of continuous girder with the cast-in-place cantilever construction method, the seismic resilience of bridges at different construction stages was researched and compared. The bridge model was established by utilizing the construction stage module in the Midas Civil finite element modelling software. The functional losses of the bridges at different construction stages were computed. The three dimensional functional surfaces of Function-Time-PGA (Peak Ground Acceleration) were drawn. The resilience indexes at different construction stages with different seismic PGAs were compared, the resilience indexes with and without consideration of the delay recovery period were compared and analysed. The research results show: 1) in the control period, the functional loss is directly proportional to the PGA, but the function and resilience indexes are inversely proportional to the PGA; 2) the seismic resilience indexes of bridges at different construction stages are vastly different; 3) the resilience indexes with and without consideration of the delay recovery period are different; for the case bridge with the delay recovery period to recovery period ratio of 20%, the difference of the resilience indexes with and without consideration of the delay recovery period can reach 17% when the seismic PGA is 1.0 g. This paper provides a new method to evaluate the seismic resilience of construction stages, and it can be used to provide suggestions for the seismic damage evaluation and post-seismic recovery scheme.
