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.

Intergeneric chromosome-specific painting reveals differential chromosomal transmission from Tripidium arundinaceum in sugarcane progeny

Sugarcane has recently attracted increasing attention for its potential as a source of sugar and bioethanol,so increasing its yield is essential to ensure the sugar security and bioenergy production.Intergeneric hybridization is a highly efficient method to produce new genetic variants of crop plants,particularly those species with high ploidy such as sugarcane(Saccharum spp.).Tripidium arundinaceum exhibits many desirable agronomic traits,and has been widely studied to produce hybrids with improved stress tolerance and other characteristics in sugarcane breeding.However,the genetic relationship between T.arundinaceum and Saccharum species,and the individual T.arundinaceum chromosomal compositions in sugarcane hybrids are still elusive.Here we used whole-genome single-nucleotide polymorphisms(SNPs)to ascertain the phylogenetic relationships between these species and found that T.arundinaceum is more closely related to Saccharum than Sorghum,in contrast to the previous narrow genetic analyses using chloroplast DNA.Additionally,oligonucleotide(oligo)-based chromosome-specific painting derived from Saccharum officinarum was able to distinctly identify the chromosomes of T.arundinaceum.We developed the oligo-genomic in situ hybridization(GISH)system for the first time,to unveil the novel chromosome translocations and the transmission of individual T.arundinaceum chromosomes in sugarcane progeny.Notably,we discovered that the chromosomal transmission of T.arundinaceum exhibited several different inheritance modes,including n,2n,and over 2n in the BC1 progenies.Such inheritance patterns may have resulted from first division restitution(FDR)or FDR+nondisjunction of a chromosome with the sister chromatids in the second meiosis division/second division restitution(FDR+NSC/SDR)model during meiosis.These results will be of substantial benefit for the further selection of T.arundinaceum chromosomes for sugarcane genetic improvement.

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.

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.

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 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.

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.

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.

A Painting of Nothing

Visitor:What does that painting represent(代表)?Artist:That is a horse grazing(吃草)in a pasture(牧场).Visitor:Where is the grass?Artist:The horse has eaten it.Visitor:But where is the horse?Artist:You don’t suppose(假定)she’d be fool enough to stay thereafter she’d eaten all the grass,do you? She weut off to anotherpasture.

Peculiar Characteristics of （Vietnamese） Painting Language： Oil Painting and Contributions From Notable Painters Including Le Van Mien, Thang Tran Phenh and Nam Son

This paper summarizes the painting artistry from three painters： Le Van Mien, Nam Son, and Thang Tran Phenh with the following notable characteristics： realism, impressionism, and contemporary humanism. It is visible from their works that these three artists have managed to define their ways to create arts reflecting the Vietnamese people in the period of transition between 19th and 20th Century Vietnam. Contemporary humanism has always been a great aspiration to any painter in any time period. During the life and work of painters, it is the visible themes of human beings in their work that best reflect how the artists perceive life. While considered to be the pioneering figures in Vietnamese oil painting registry of art, the three painters Le Van Mien, Nam Son, and Thang Tran Phenh all happened to favor the humanism theme in their oil painting works. There were two most commonly accepted explanations for this choice. First of all, most artistic geometry lessons for beginners often choose the human figure to be the starting model for study and creative development. Secondly, during the tram-century period when Eastern and Western cultures collided in Vietnam during the late 19th early 20th Century, humans and most notably the Confucianists were the most vivid storytellers of the day and age.

Technical Notes on Tibetan Tantric Buddhist Painting Artistic Heritage and Traditional Techniques

Among various arts and crafts in Tibet, painting appears to enjoy a uniquely crucial position in both the religious centres and the lives of ordinary Tibetan people. This paper examines the traditional techniques, methods, and materials used in Tibetan （Tantric） Buddhist painting by observing its working process at first hand, and having attended a number of its exhibitions, art workshops, and other resources both at home and overseas. The survey of the technical aspect of Tibetan painting is primarily based upon the general usage of materials, as well as the method and the usual order of their application that relates to most kinds of mural paintings in Tibet, and which are less well-known in the West This paper aims to present a rich and somewhat complicated range of methods and materials of Tibetan （Tantric] Buddhist art tradition. To its end, the author hopes it also provides more indication of its possible influence of the traditional artistic wealth in Tibet on contemporary artists working in relation to this culture.

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.

A Comparison of Watercolor Painting and Boneless Painting:From Technique to Connotation

Watercolor painting is a western painting method,which is concerned with the relationships of light and shadow as well as brightness and darkness.Chinese painting includes brush painting and ink painting;there is a special painting method that is known as“boneless painting.”This technique involves painting directly with color without outlining,and it is between brush painting and freehand brushwork.Both,boneless painting and watercolor painting are rich in color expression,and their techniques have many similarities in expressing the relationship between man and nature as well as the inner feelings of the painter.Watercolor painting was introduced to China from the West at the end of the 19th century,and it soon became a popular type of painting.The technique of brush painting in boneless painting has a history of several thousand years,from the Warring States period to the Song Dynasty.It pursues the shape of modeling and focuses on realism.Boneless painting,on the other hand,is mainly concerned with flowers and birds,between brush painting and painting with a sense of style,without outlining,directly painting flowers and leaves with colors or ink.They are both painted with brushes on paper,and they use water as a medium to mix pigments.The wet and dry intensity of watercolor painting as well as the interplay of ink and colors in Chinese painting have both developed their own unique charms.The two different types of painting represent the cultural epitomes of two different nationalities.In contemporary times,the techniques of watercolor painting and Chinese painting can be learned from each other.This paper explores the different connotations and expressions of boneless painting and watercolor painting through the combing of watercolor and Chinese painting techniques.

Discussion on the Relation between Garden Landscape Constitution and Ancient Chinese Poetry and Paintings

From the perspective of culture-based source,the author considered that the ancient Chinese poetry and paintings not only embodied the harmony and unity thought of man and nature,but also were the emotional attachment of Chinese literati.As a diverse and comprehensive aesthetic art,landscape expressed material and spiritual culture doubly,the spiritual connotation of which was inextricably linked within ancient Chinese poetry and paintings.In addition,ancient Chinese poetry and paintings can be directly used in landscape composition,such as the widely used in plaques,inscriptions,couplets,poems and inscriptions,carved beams and painted pillars,painting with words and so on.Chinese literati integrated the ethereal realm of poetry and paintings into garden art,making landscape endow with poetic charm.Therefore,the landscape revealed the traces of literature and arts in aesthetic idea and taste,pushing Chinese garden to a higher aesthetic realm.This study pointed the right way to the future of modern landscape which advocated ecological and harmonious development.

The influence of modern painting on Faulkner in Go Down, Moses

Challenging traditional Western painting rules, modem paintings depict one object from multi-angles and advocate the autonomy of art. Seldom do people know that Faulkner loved painting when he was young and modem paintings exert a subtle influence on him. In his Yoknapatawpha, William Faulkner breaks the time and space order and the consistency of plot in traditional novels, which demonstrates aesthetic effect of modem painting and embodies the allegation of modern painting that art is autonomous. This paper will analyze the deep influence of modern painting on Faulkner＇s writing techniques and language characteristics, providing a new perspective to aonreciate the art of Faulkner＇s Yoknapatawpha.

Characterization of Two Human Lung Adenocarcinoma Cell Lines by Reciprocal Chromosome Painting

Lung cancer is a leading cause of cancer death worldwide. Some lung cancer patients correlate with a gas of radon besides smoking. To search for common chromosomal aberrations in lung cancer cell lines established from patients induced by different factors, a combined approach of chromosome sorting, forward and reverse chromosome painting was used to characterize karyotypes of two lung adenocarcinoma cell lines： A549 and GLC-82 with the latter line derived from a patient who has suffered long-term exposure to environmental radon gas pollution. The chromosome painting results revealed that complex chromosomal rearrangements occurred in these two lung adenocarcinoma cell lines. Thirteen and twenty-four abnormal chromosomes were identified An A549 and GLC-82 cell lines, respectively. Almost half of abnormal chromosomes in these two cell lines were formed by non-reciprocal translocations, the others were derived from deletions and duplication/or amplification in some chromosomal regions. Furthermore, two apparently common breakpoints, HSA8q24 and 12q14 were found in these two lung cancer cell lines.
