Investigation of the Film Formation in Dynamic Air Spray Painting

To accurately predict the film thickness distribution during dynamic spraying performed with air guns and support accordingly the development of intelligent spray painting,the spray problem was analyzed numerically.In particular,the Eulerian-Eulerian approach was employed to calculate the paint atomization and film deposition process.Different spray heights,spray angles,spray gun movement speeds,spray trajectory curvature radii,and air pressure values were considered.Numerical simulation results indicate that the angle of spray painting significantly affects the velocity of droplets near the spray surface.With an increase in the spraying angle,spraying height and spray gun movement speed,the maximum film thickness decreases to varying degrees,and the uniformity of the film thickness also continuously worsens.When the spray gun moves along an arc trajectory,at smaller arc radii,the film thickness on the inside of the arc is slightly greater than that on the outside,but the impact on the maximum film thickness is minimal.Increasing air pressure expands the coating coverage area,results in finer atomization of paint droplets,and leads to a thinner and a more uniform paint film.However,if the pressure is too high,it can cause paint splattering.Using the orthogonal experimental method,multiple sets of simulation calculations were conducted,and the combined effects of spraying height,spray angle,and spray gun movement speed on the film thickness distribution were comprehensively analyzed to determine optimal configurations.Finally,the reliability of the numerical simulations was validated through dynamic spray painting experiments.

Improved Scatter Search Algorithm for Multi-skilled Personnel Scheduling of Ship Block Painting

This paper focuses on the optimization method for multi-skilled painting personnel scheduling.The budget working time analysis is carried out considering the influence of operating area,difficulty of spraying area,multi-skilled workers,and worker’s efficiency,then a mathematical model is established to minimize the completion time. The constraints of task priority,paint preparation,pump management,and neighbor avoidance in the ship block painting production are considered. Based on this model,an improved scatter search(ISS)algorithm is designed,and the hybrid approximate dynamic programming(ADP)algorithm is used to improve search efficiency. In addition,the two solution combination methods of path-relinking and task sequence combination are used to enhance the search breadth and depth. The numerical experimental results show that ISS has a significant advantage in solving efficiency compared with the solver in small scale instances;Compared with the scatter search algorithm and genetic algorithm,ISS can stably improve the solution quality. Verified by the production example,ISS effectively shortens the total completion time of the production,which is suitable for scheduling problems in the actual painting production of the shipyard.

The Study of “Imitation” Aesthetics in Ancient Painting Theory-Taking the Chinese and Western Sources as an Example

The theory of“imitation”in painting occupies a leading position in western art,which originated from the theory of“imitation”in ancient Greece,and has become one of the art theories affecting the world through the continuous development of later generations.Through the exploration of the source of“imitation”in China and the West,there are some comments on the meaning of“imitation”in Chinese classical painting theory,such as“transfer model writing”and“image form”,which is obvious differences from the west.Traditional Chinese painting is a combination of careful observation of natural things and subjective emotions to express their own aesthetic feelings,and ultimately form a vivid artistic conception.Modern imitation is borrowed from Western imitation.In fact,imitation in traditional painting has its own meaning,which contains Chinese aesthetic thought.“Imitation”aesthetics is unique in traditional Chinese painting and is the most important form of painting art.

Exploration of the Expression of Color Emotion in Oil Painting Sketch Creation

This paper deeply analyzes the expression of color emotion in oil painting sketch creation.Starting with the three basic attributes of color theory(hue,lightness,and purity),this paper discusses its emotional symbolic significance and the relationship between contrast and harmony.By interpreting the works of artists such as Van Gogh’s Sunflower,Monet’s Rouen Cathedral,and Cézanne’s Mont Sainte-Victoire,this paper shows the unique charm of different colors in conveying emotions,creating atmosphere,and expressing themes.At the same time,it is expounded that in the creation of an oil painting sketch,the effective expression of color emotion can be realized by observing nature,using subjective colors,and reasonable composition and layout of colors,so as to enhance the artistic value of the works.

Analysis of Color and Artistic Conception in Painting Art

The charm of painting,as a bright pearl in the treasure house of culture,lies in its visual language constructed through colors and lines,which conveys the artist’s unique perception of life and profound emotions.Color,as the most intuitive and expressive language in painting,is not only a simple reproduction of material colors but also a projection of the artist’s inner world.Artistic conception,as a core concept in traditional Chinese painting theory,refers to the emotional atmosphere and spiritual mood embedded in paintings.The purpose of this paper is to discuss the interaction between color and mood in painting art,to analyze the techniques of using color in different painting styles and their influence on the creation of mood,and to provide new perspectives and methods for the creation of paintings.

Color Expression and Mood Creation in Imagery Oil Painting

Oil painting is a traditional Western painting form.With the introduction of China and the influence of China’s traditional painting and aesthetics,the painting style became more distinctive,expanding a new development direction of oil painting,and thus imagery oil painting came into being.Color,as the most important element in imagery oil painting,mainly plays the role of mood creation and emotional expression.Many creators are good at injecting their thoughts and emotions into the paintings through color matching,so as to enhance the artistic expression of the paintings.This paper analyzes the color expression characteristics of imagery oil painting and explores the color expression techniques in imagery oil painting and mood creation of imagery oil painting from several aspects.

Analysis of Viewing Paintings from the Perspective of Iconography

Distinguished from purely formalistic research methods,iconography pursues the interpretation of the hidden historical and humanistic connotations behind artworks,and is a discipline that combines visual text and content analysis methods.Combining the three stages of iconography proposed by Panofsky,the paper studies Shizeng Chen’s Viewing Paintings from the perspective of iconography,summarizing the formation and change of the images and contents of the artworks in the cultural system and civilization at that time,as well as their implied ideology,and analyzing the hidden spirit of the times and the historical significance behind them,so as to expound their iconographic significance.Through an in-depth discussion at three levels:pre-pictorial iconographic description,iconographic analysis,and iconographic interpretation,the facts and surface contents reproduced in the images,the traditional level of literary,artistic,and cultural knowledge,as well as the interpretation of the potential meanings are revealed.

Painting Therapy in Cancer Care: A Descriptive Systematic Review

Background: Despite art therapy has been widely used in cancer population to improve their physical and mental health, painting therapy, as one form of art therapy, is seldom applied to adult cancer patients independently. Therefore, how painting therapy affects adult cancer patients’ health outcomes needed to be explored sufficiently. Objectives: The purpose of this review was to assess and synthesize the latest evidence of painting therapy concerning adult cancer patients, and to provide some inspiration for clinical staff. Methods: A literature research of PubMed, Web of Science, Cochrane Library, EMBASE, CINAHL, PsychoInfo, Psydex, CENTRAL, Google Scholar, British Library, CNKI, Wanfang, CQVIP electronic databases were undertaken with the following key words: art therapy, painting, drawing, cancer, neoplasm, tumor, carcinoma and oncology. A narrative synthesis was used according to PRISMA and the quality of study was assessed using acritical assessment tool. Results: Eleven papers reporting nine different research projects met the inclusion criteria. Generally speaking, painting therapy positively affected health outcomes. The impacts on patients include improvements in quality of life, coping with disease, mental health and somatic symptoms. However, inconsistency still exists. Three studies failed to show positive effects of painting therapy on post-traumatic growth, distress and coping behavior in participants. Conclusion: Robust evidence was found in rehabilitation of patients with various types of cancer. Painting therapy evidently affected cancer patients in a positive direction. However, the application of painting therapy to cancer patients needs to be explored further due to few studies on this topic.

APST-Flow: A Reversible Network-Based Artistic Painting Style Transfer Method

In recent years,deep generative models have been successfully applied to perform artistic painting style transfer(APST).The difficulties might lie in the loss of reconstructing spatial details and the inefficiency of model convergence caused by the irreversible en-decoder methodology of the existing models.Aiming to this,this paper proposes a Flow-based architecture with both the en-decoder sharing a reversible network configuration.The proposed APST-Flow can efficiently reduce model uncertainty via a compact analysis-synthesis methodology,thereby the generalization performance and the convergence stability are improved.For the generator,a Flow-based network using Wavelet additive coupling(WAC)layers is implemented to extract multi-scale content features.Also,a style checker is used to enhance the global style consistency by minimizing the error between the reconstructed and the input images.To enhance the generated salient details,a loss of adaptive stroke edge is applied in both the global and local model training.The experimental results show that the proposed method improves PSNR by 5%,SSIM by 6.2%,and decreases Style Error by 29.4%over the existing models on the ChipPhi set.The competitive results verify that APST-Flow achieves high-quality generation with less content deviation and enhanced generalization,thereby can be further applied to more APST scenes.

Chinese Sources for AfterWards:From Premodern Poetry,Paintings,and Medical Texts to Modern Novels,Film,and Documentaries

This paper focuses on Chinese sources suggested for a narrative medicine(NM)program,called AfterWards.Dr Lauren Small established AfterWards in 2014 and has been coordinating it since out of the Pediatrics Department at Johns Hopkins Medicine.In early 2019,she started giving a series of lectures and workshops about AfterWards to Chinese medical educators and clinicians in Beijing and Shanghai.She created an AfterWards Facilitator’s Guide based on Western-language sources for workshop participants.She also started to organize with Jiang Yuhong(Peking Union Medical College)a workshop for Chinese colleagues to be held at Johns Hopkins Medicine in October 2019.They invited the author to participate.The idea was hatched then to develop Chinese source materials following the AfterWards structure for an updated Facilitator’s Guide that Dr Small had initially written.A typical one-hour AfterWards session consists of a specific five-part structure:a literary text or artwork,an associated theme,discussion topics,a writing exercise,and shared reflection.While the content of the program always changes from session to session,the basic structure remains the same.This paper summarizes the types of Chinese sources and their related narrative-medicine themes that were originally selected for inclusion in the updated AfterWards Facilitator’s Guide intended for Chinese colleagues.These sources about coping with sick family members,aging,and illness ranged from the textual(classical Chinese poems on aging and diagnostic forms for training students)and visual(premodern Chinese paintings and murals of medical encounters)to the fictive(novels)and performative(contemporary Asian-American film in English and Chinese-language film and documentaries).

In traditional landscape painting in China,water has always occupied an important artistic position and space,and painters in different ages had different ways to express water.Systematically sorting out the methods of water painting in Chinese painting is of great significance for us to gain a comprehensive understanding of the artistic styles,cultures and artistic languages of different times.It is also of great reference value for those learning Chinese painting.

Aesthetic Utopia,Revolution in Daily Life and Identity Construction of Peasant Paintings

Peasant painting is a kind of painting created by farmers as creative subject,bearing rich significance.According to the historical development of peasant painting in reality,the types of meaning it carried could be divided into three types in chronological order:political ideological significance,folk life significance,and creative fashion significance.These three types of meaning gave rise to three types of aesthetic utopia,namely political aesthetic utopia,folk aesthetic utopia and fashion aesthetic utopia.The three types of aesthetic utopia reflected three forms of negation and revolution of daily life.What the political aesthetic utopia resisted was the alienation force of material desire.What folk aesthetic utopia resisted was the desire for material and the binding of political ideology.The fashion aesthetic utopia opposed the relatively narrow localism.Through these three forms of resistance,the public also constructed three identities:the interpreter of their own aesthetic interpretation of political ideology,the interpreter of their own aesthetic interpretation of real life from perspective of local feelings,and the interpreter of their own aesthetic interpretation of real life from perspective of the relationship between themselves and the world.

Discussing the Teaching of Impressionist Chinese Painting in the Context of Art and Cultural History

Ink freehand brushwork is the soul and the highest level of artistic spirit in art categories such as painting and sculpture.Sculpture art and Chinese ink painting art have their own commonalities.I attempted to investigate the stone carvings of Huo Qubing’s tomb in the Western Han Dynasty,combined with Tang Dynasty tomb carvings,which greatly helped me in the creation of Chinese ink painting art.I drew inspiration and nutrients from it,and realized what is art.What is the spirit of art?You can find the answer from it.

Exploring Taiwan’s China Landscape Painting Aesthetic Preferences Through Evaluation Grid Method and the Continuous Fuzzy Kano Model

The primary objective of this study is to apply the Evaluation Grid Method(EGM)and the continuous fuzzy Kano quality model to explore the cognitive preferences of Taiwan China residents regarding the beauty of Taiwan’s China landscape paintings.The aim is to contribute to the development of social and cultural art and promote the widespread appeal of art products.Through a literature review,consultations with aesthetic experts,and the application of Miryoku Engineering’s EGM,this paper consolidates the factors that contribute to the attractiveness of painting art products among Taiwan China residents,taking into account various aesthetic qualities.Simultaneously,the paper introduces the use of the triangular fuzzy golden ratio scale semantics,specifically the equal-ratio aesthetic scale semantics,as a replacement for the traditional subjective consciousness model.Departing from the traditional discrete Kano model that employs the mode as the standard for evaluating quality,this study applies triangular fuzzy numbers to the continuous Kano quality model to analyze the diverse preferences and evaluation standards of the public.The hope is that this research methodology will not only deepen Taiwan China residents’understanding and aesthetic literacy of painting art but also serve as a reference for the popularization of art products.

Karyotypic evolution in family Hipposideridae (Chiroptera, Mammalia) revealed by comparative chromosome painting, G- and C-banding

Comparing to its sister-family （Rhinolophidae）, Hipposideridae was less studied by cytogenetic approaches. Only a few high-resolution G-banded karyotypes have been reported so far, and most of the conclusions on the karyotypic evolution in Hipposideridae were based on conventional Giemsa-staining. In this study, we applied comparative chromosome painting, a method of choice for genome-wide comparison at the molecular level, and G- and C-banding to establish comparative map between five hipposiderid species from China, using a whole set of chromosome-specific painting probes from one of them （Aselliscus stoliczkanus）. G-band and C-band comparisons between homologous segments defined by chromosome painting revealed that Robertsonian translocations, paracentric inversions and heterochromatin addition could be the main mechanism of chromosome evolution in Hipposideridae. Comparative analysis of the conserved chromosomal segments among five hipposiderid species and outgroup species suggests that bi-armed chromosomes should be included into the ancestral karyotype of Hipposideridae, which was previously believed to be exclusively composed of acrocentric chromosomes.

PYRAMIDAL MULTIPHASE LEVEL SET FRAMEWORK FOR BRAIN TUMOR DETECTION USING GENERALIZED TECHNIQUE OF PAINTING BACKGROUND

The pyramidal multiphase level set framework （PMLSF） based on the technique of painting background （TPBG） and the Chan-Vese model can detect multiple objects on a given image. However, the boundaries of the sub-object obtained by PMLSF-TPBG are not variable since a specialcolor parameter is used in TPBG. To solve the problem, a new technique utilizing a varying parameter is proposed to ensure that PMLSF is effective for the detection of the desired boundaries of the sub-object. The interval of the variable color parameter is proved and the effects of the parameter are also discussed. Experimental results for the brain tumor detection show that different boundaries of the brain tumors can be detected with different color parameters. It is especially useful for clinical diagnoses.
