An Image Fingerprint and Attention Mechanism Based Load Estimation Algorithm for Electric Power System

With the rapid development of electric power systems,load estimation plays an important role in system operation and planning.Usually,load estimation techniques contain traditional,time series,regression analysis-based,and machine learning-based estimation.Since the machine learning-based method can lead to better performance,in this paper,a deep learning-based load estimation algorithm using image fingerprint and attention mechanism is proposed.First,an image fingerprint construction is proposed for training data.After the data preprocessing,the training data matrix is constructed by the cyclic shift and cubic spline interpolation.Then,the linear mapping and the gray-color transformation method are proposed to form the color image fingerprint.Second,a convolutional neural network(CNN)combined with an attentionmechanism is proposed for training performance improvement.At last,an experiment is carried out to evaluate the estimation performance.Compared with the support vector machine method,CNN method and long short-term memory method,the proposed algorithm has the best load estimation performance.

A Brief Analysis on the Construction of Subject Image in the Self-Documentary "Small Talk"

Taiwan Residents producer Huang Hui-zhen directed the camera at her mother and herself,trying to communicate and reconcile with her mother through documentary.Different from other private record documentaries,the conflicts within the subject construction in Small Talk is no longer limited to“person to person”,“person and family”,or“parents and children”.Instead,it constructs the theme of an ordinary family struggling with a collection of social issues such as homosexuality,domestic violence,sexual assault,aboriginal Taiwan Residents culture,etc.

Images Construction of Soldiers in News Photos of World War II-Take the Example of News of China During the Period from 1942 to 1946

The news photos of News of China are important historical evidence of reflecting the historical reality of anti-fascist war.Content analysis method is used in this article to analyze the soldiers’images constructed in these news photos.From the research we can learn that the News of China presented the image of Chinese soldiers who struggled in trouble at home and abroad,and the image of the Chinese and American soldiers who united together as a whole to fight against the fascist enemy during the World War II.During the war,it inspired people’s hearts and cohesion of social forces,and laid a foundation for the progress of aid to China and the victory of the anti-fascist war.

Personal Urbanities： Domesticating the Public Domain

City and personality have never been easily associated. Historically, since classical antiquity, urban space has always been the reflection of a collective identity representing the natural inclination of human beings to live in group. However, according to Lewis Mumford, the city has been the context in which another ideal arose--the concept of personality. This ideal, according to the official history of urban design, seems to have had a very marginal role, if not as a formal or functional analogous structure. Nevertheless, looking at the physical consistence of built space--as well as its ideal formulation--it is not difficult to find some evidence of Mumford＇s theory. Therefore, the paper, through an architectural overview ranging from classical street-side benches to contemporary digital cities, aims at outlining the progressive change in the representation of urban identities from a collective to a more personal dimension. It describes how public space design, especially during the last 30 years, has redefined its strategies in order to increase the possibilities of personal intervention for users, and it focuses on the gradual shift of this discipline towards other scales, instruments and objectives, in a sudden disciplinary convergence with interior architecture and industrial design. Thus, showing how a pervasive process of domestication is nowadays transforming not only the use, but also the symbolic meaning that the public domain has traditionally had.
