Orchestration of Experience

The sensory experience shaped by the landscape unconsciously influences people’s emotional and mental states. Contemporary urban landscape designers prioritized the functionality of the landscape, sometimes ignoring the spiritual impact of the atmosphere created by imperceptible environmental sonic factors. Orchestration of Experience explores the connections between sound and vision in shaping people’s sensory experience of the landscape. Drawing from soundscape ecology, environmental psychology, and dynamic visualization, this study demonstrates how they are closely intertwined. Motivated by the idea that white noise can unconsciously affect people’s mental health by Michael Rutter, we question how physical and sound landscapes shape each other, how they can shape spatially charged environmental atmospheres, and how the universal experience-creating process can potentially create more immersive experiences for people who experience hearing or visual impairment. The ultimate goal of this work is to encourage new ways of sharing and engaging with the environment thus en-hancing people’s sensory experiences in the landscape

An Information-theoretic Visual Analysis Framework for Convolutional Neural Networks

Despite the great success of Convolutional Neural Networks (CNNs) in Computer Vision and Natural Language Processing, the working mechanism behind CNNs is still under extensive discussions and research. Driven by a strong demand for the theoretical explanation of neural networks, some researchers utilize information theory to provide insight into the black box model. However, to the best of our knowledge, employing information theory to quantitatively analyze and qualitatively visualize neural networks has not been extensively studied in the visualization community. In this paper, we combine information entropies and visualization techniques to shed light on how CNN works. Specifically, we first introduce a data model to organize the data that can be extracted from CNN models. Then we propose two ways to calculate entropy under different circumstances. To provide a fundamental understanding of the basic building blocks of CNNs (e.g., convolutional layers, pooling layers, normalization layers) from an information-theoretic perspective, we develop a visual analysis system, CNNSlicer. CNNSlicer allows users to interactively explore the amount of information changes inside the model. With case studies on the widely used benchmark datasets (MNIST and CIFAR-10), we demonstrate the effectiveness of our system in opening the blackbox of CNNs

Analysis and Measures of Main Influencing Factors on Cold Filter Point Test of Diesel Oil

The cold filter point is one of the important indexes to measure the low temperature performance of oil products, and the accurate measurement of the cold filter point of diesel oil has important practical significance to ensure the normal operation of the diesel engine. This paper first introduces the basic concept of cold filter point, and then analyzes the main factors affecting the test of diesel cold filter point, including the installation of cold filter point equipment, test operation process and so on. The test results show that the reliability of the test equipment and facilities and the standardization of operation have a certain influence on the cold filter point of diesel oil. Only the equipment and facilities which strictly control the cold filter point and test under the prescribed conditions can the results of the cold filter point be accurately tested

Design of Image Copy-Paste Forensics System Based on Moment Invariants

Copy-paste tampering is a common type of digital image tampering, which refers to copying a part of the image area in the same image, and then pasting it into another area of the image to generate a forged image, so as to carry out malicious operations such as fraud and framing. This kind of malicious forgery leads to the security problem of digital image. The research of digital image copy paste forensics has important theoretical significance and practical value. For digital image copy-paste tampering, this paper is based on moment invariant image copy paste tampering detection algorithm, and use Matlab software to design the corresponding tampering forensics system

Features and Applications of QR Codes

QR code refers to the expansion of another one-dimensional readable bar code based on one-dimensional bar code, which uses black-and-white rectangular pattern to represent binary data, and the information contained in it can be obtained after being scanned by the equipment. Like the previous one-dimensional bar code, two-dimensional bar code is widely used in commercial activities, especially in high-tech industry, storage and transportation industry, wholesale and retail industry and other industries that need cheap and fast labeling information for goods

Chemical and isotopic analysis in the investigation of glazes from Northern China and the Middle East, 7th-14th centuries AD

Both Chinese and Islamic glazed ceramics played a significant role in the history of ancient ceramic production. Moreover, it was innovation in glazes that made the Chinese and Islamic ceramics constantly innovative in various categories with different manufacturing techniques. This study applies chemical and isotopic analyses to investigate the manufacturing techniques and provenances of different types of glazes from Northern China and the Middle East, and extends the use of Sr isotopic analysis to investigate raw materials and glaze recipes used to making lime/alkaline glazes in Northern China and the Middle East for the first time. By chemical compositions of the lead glazes, the glazing techniques used to produce Chinese Tang Sancai lead glazes and splashed lead glazes from the Middle East have been identified. The mixture of lead oxide plus quartz/quartz sand was used for making both Chinese Tang Sancai glazes and Islamic splashed lead glazes. Besides, for the Chinese lead glazes, the trace element and lead isotopic analyses of them have been effective in grouping glazes made in different production kiln sites, and hence associating the Tang Sancai wares excavated from archaeological sites of unknown origin with their production centres. Furthermore, by comparing the lead isotopic ratios of Islamic lead glazes and those of lead ore deposits, the possible sources of lead used for making lead glazes can be determined, although more than one source was suggested due to the overlap of Pb isotopic ratios of different lead ore sources in some cases. This study is the first time that Sr isotopic analysis has been applied to the lime/alkaline glazes from Northern China and the Middle East. It has revealed that Sr isotopic compositions of lime/alkaline glazes from Northern China and the Middle East have been very effective in providing information on the glaze recipes and characteristics of raw materials used for making them. Based on Sr isotopic compositions, the case study of Nothern Chinese lime glaze has identified that the Yaozhou celadon glaze was probably produced by local ‘Fuping glaze stone’ combined with botanic ash. Besides, the case study of the Middle East alkaline glaze has suggested that the Raqqa ware glaze was probably made by ‘Cenozoic sand’ containing a certain content of limestone grains and feldspar and that botanic ash was used as a flux
