Abstract: An image captured in rain reduces the visibility quality of image which affects the analytical task like detecting objects and classifying pictures. Hence, image de-raining became important in last few years. Since pictures taken in rain include rain streaks of all sizes, single image de-raining is becoming much difficult issue to solve, which may flow in different direction and the density of each rain streak is different. Rain streaks have a varied effect on various areas of picture, and hence it becomes important for removing rain streak from rainy pictures as rainy images tend to lose its high frequency information; previously many methods were proposed for this purpose but they failed to provide accurate results. Hence we have studied and implemented a supervised machine learning method using convolutional neural network (CNN) algorithm to get more accurate result of rain streak removal from an image captured during rain and in less elapsed time by preserving high rated information of image during removal of rain streak. Keywords: CNN, elapsed time, single image de-raining, supervised machine learning, rain streaks.

AbstractThe quality of photos is highly susceptible to severe weather such as heavy rain; it can also degrade the performance of various visual tasks like object detection. Rain removal is a challenging problem because rain streaks have different appearances even in one image. Regions where rain accumulates appear foggy or misty, while rain streaks can be clearly seen in areas where rain is less heavy. We propose removing various rain effects in pictures using a hybrid multiscale loss guided multiple feature fusion de-raining network (MSGMFFNet). Specially, to deal with rain streaks, our method generates a rain streak attention map, while preprocessing uses gamma correction and contrast enhancement to enhanced images to address the problem of rain accumulation. Using these tools, the model can restore a result with abundant details. Furthermore, a hybrid multiscale loss combining L1 loss and edge loss is used to guide the training process to pay attention to edge and content information. Comprehensive experiments conducted on both synthetic and real-world datasets demonstrate the effectiveness of our method.

AbstractThe “eclipse glyph,” as it is called by most people in our field, is not referring to eclipses, but rather to the darkened sun and moon associated with heavy rainfall or darkened skies. This glyph is composed of the sun sign or moon sign (occasionally others) between two flanking fields, usually one light and one dark, and is found principally in the Postclassic divinatory almanacs of the Maya codices. Evidence for this proposal comes from iconography as well as texts. Rain pours from “eclipse glyphs” in pictures accompanied by hieroglyphic captions explicitly dealing with rain; they also appear in calendrical sequences that could not possibly be referring to eclipses. Even in the lunar or eclipse pages in theDresden Codexthat deal with solar eclipses, the texts that accompany the “eclipse glyphs” are about rain. A search of Classic-period antecedents suggests a linguistic valueyihk'in, meaning “darkened” or “darkening.”

Rain removal from pictures taken under bad weather conditions is a challenging task that aims to improve the overall quality and visibility of a scene. The enhanced images usually constitute the input for subsequent Computer Vision tasks such as detection and classification. In this paper, we present a Convolutional Neural Network, based on the Pix2Pix model, for rain streaks removal from images, with specific interest in evaluating the results of the processing operation with respect to the Optical Character Recognition (OCR) task. In particular, we present a way to generate a rainy version of the Street View Text Dataset (R-SVTD) for "text detection and recognition" evaluation in bad weather conditions. Experimental results on this dataset show that our model is able to outperform the state of the art in terms of two commonly used image quality metrics, and that it is capable to improve the performances of an OCR model to detect and recognise text in the wild.

English phrasal verbs such as ‘call off’ (a game due to rain) and (the buttons) ‘come off’ are difficult for non-native speakers to learn because the meanings of many phrasal verbs are not compositions of the meanings of each component. It was reported that the use of phrasal verbs was avoided by non-native speakers and that the mastery of collocations was hampered by a strong influence from the learner's native language. Therefore, to prevent such interference from learners’ native languages, it would be appropriate to learn phrasal verbs directly through nonverbal media such as pictures and sound. A web application was developed for the picture-based e-learning of phrasal verbs. An experiment was conducted, which consisted of a sequence of two sessions with a week-long break in between. In order to investigate the learning effectiveness, two methods were compared: one with the display of meaning with still pictures, and the other with Japanese word glosses. Two groups participated in the experiment, and each group had both methods. The only difference was the sequence of the order of the two methods. This paper reports the comparative results of the two post-tests by the two groups, discusses some of the findings, and offers several suggestions.

The paper is an attempt to analyse the photographs in the travel brochures. The brochures created by the Kerala Government are considered as sample for analysis. The photographs used in creating the brochures are to attract the targeted travellers from other countries, so it will be shown as the best representation of a place. The photoshopped images of Kathakali, rain forests and backwaters are not the real pictures of the place which becomes the prominent pictures on the Travel Brochures every year. Some latest photos are of Theyyam and the traditional Hindu art forms. The pictures are the representation of perspectives, it focuses on what we need to see and show. Photography is a deliberate attempt to show the unreal conditions and building a “reality” out of gaze. The earlier postcolonial representations of human beings are shifted to the exotic representation of nature and art forms which are exploited.

This study examines the Film Dancing In The Rain produced by Screenplay Films Legacy Pictures which tells the life of an autistic child who gets discriminated against from the surrounding environment. The purpose of the study was to examine the moral message contained in Dancing In The Rain using Roland Barthes' Semiotic Analysis. Researchers specifically examined how the background to the emergence of Dancing In The Rain, how semiotics analysis of Dancing In The Rain, and what are the moral messages in Dancing In The Rain. This study uses qualitative methods by researching film series and audience responses. The data collection techniques used are observation, interview, and documentation. The results of this study show that the background of the emergence of Dancing In The Rain is the idea of the screenwriter to make a humanist film so that the audience can see that we are not perfect or surrounded by imperfect people and in order to better appreciate imperfections. The study also found pieces of the scene that had a moral message that the authors of the analysis used Roland Barthes Semiotics Analysis. The meaning of the denotations, connotations, and myths of the film has been mentioned in the chapter's findings. The moral message contained in this film is 3, namely the message of friendship, the message of non-discrimination that is how the life of autistic children is treated in society, and the message of sincerity and sincerity in friendship.

Prosopanche panguanensis, from the Peruvian lowland rain forest, is proposed as a new species. The species is similar to Prosopanche costaricensis but differs with solitary flowers (vs. flowers in fascicles), a perigonial tube prolonged above the insertion point of the synandrium (vs. perigonial tube not prolonged), and staminodes cucullate and sessile (vs. bilobed in the apex). A description, illustrations, pictures of live specimens, and information about its habitat and distribution are given. An account on Prosopanche specimens recorded from Peru and their identity is also provided.

The secretarybird, the only species of the family Sagittariidae (Falconiformes), inhabits all of sub-Saharan Africa except the rain forests. Secretarybird, its vernacular name in many languages, may be derived from the Arabic “saqr at-tair”, “falcon of the hunt”, which found its way into French during the crusades. From the same period are two drawings of a “bistarda deserti” in a codex by the Holy Roman Emperor Frederick II (1194–1250). The original sketch obviously, together with other information on birds, came from the court of Sultan al-Kâmil (1180–1238) in Cairo. Careful examination led to an interpretation as Sagittarius serpentarius. Two archaeological sources and one nineteenth century observation strengthened the idea of a former occurrence of the secretarybird in the Egyptian Nile valley. André Thevet (1502–1590), a French cleric and reliable research traveller, described and depicted in 1558 a strange bird, named “Pa” in Persian language, from what he called Madagascar. The woodcut is identified as Sagittarius serpentarius. The text reveals East Africa as the real home of this bird, associated there among others with elephants. From there raises a connection to the tales of the fabulous roc, which feeds its offspring with elephants, ending up in the vernacular name of the extinct Madagascar ostrich as elephantbird.

‘Pictures are forming inside my brain Soon with the colours they’ll rain together and grow Then don’t you know, don’t you know, there’ll be music.’From ‘Music’ by Carole King.To explore individual narratives of a therapist’s route to entering the profession, I undertook a self-critical analysis of personal experiences, emotional understandings, and meaning making of my life prior to becoming a counselling psychologist. Pathways to entering a psychotherapeutic profession are nuanced, and idiosyncratic, so rather than the ubiquitous ‘wounded healer’ narrative being the sole applicable metaphor for my life journey, I draw out another metaphor more pertinent to my particular experience: the music of therapy.

Abstract:Seed-consuming rodents are increasingly recognized for their roles in the maintenance of tree species diversity, by acting on crucial post seed-dispersal processes. Yet, studies examining the extent to which rodents may act as secondary seed dispersers and/or predators in Madagascar's forests are limited. Thread-marking seed experiments were run to address this, using the seeds of two native large-seeded, frugivore-dispersed tree species (Abrahamia thouvenotii and Cryptocarya crassifolia), in disturbed and less-disturbed habitats in the rain forests of Ranomafana National Park, during the dry season. Data show that post-dispersal handling of seeds by rodents (predation and removal) was significantly lower in disturbed than in less-disturbed habitats (1.31–3.78 times lower; n = 2200). Also, seeds were more likely to be predated or left on the forest ground after removal than being larder- or scatter-hoarded: 27–78% of the removed seeds were found on the ground, <12% found in burrows and there was no evidence of scatter-hoarding (n = 132). Based on pictures from camera traps, the native rodent species, Nesomys rufus, was potentially responsible for seed predation and/or removal in the less-disturbed habitat; but no indication of the rodent species active in the disturbed habitat was obtained. The lack of scatter-hoarding suggests a limited role of rodents in secondary seed dispersal in this system. These findings form a preliminary account of the potential roles of rodents in post seed-dispersal processes in Madagascar's forests, but this warrants further study.

A literature review aids in comprehending and gaining further information about a certain area of a subject. The presence of haze, fog, smoke, rain, and other harsh weather conditions affects outdoor photos. Images taken in unnatural weather have weak contrast and poor colors. This may make detecting objects in the produced hazy pictures difficult. In computer vision, scenes and images taken in a foggy atmosphere suffer from blurring. This work covers a study of many remove haze algorithms for eliminating haze collected in real-world weather scenarios in order to recover haze-free images rapidly and with improved quality. The contrast, viewing range, and color accuracy have been enhanced. All of these techniques it is used in countless fields. Some of the applications that use this technology outdoor surveillance, object recognition, underwater photography, and so on.

The study of an active western disturbance which moved across north Pakistan and Jammu & Kashmir in the month of November 1986 has, been presents. The importance of this study lies in the fact that this western disturbance, which had produced widespread precipitation With heavy falls It a number of places, has occurred in a relatively dry month, November, The main emphasis In this study is about the temperature distribution of the top of the clouds associated with the disturbance as seen frOI1l the infrared satellite pictures. An attempt has been made to understand the relation between the cloud top temperatures and the resultant rainfall. Comparison has been made between the rainfall estimate using Arkin's methodology and the actual average rainfall based on rain gauge stations. It IS seen that the threshold cloud top temperature (CIT) of 235° K to give an average rainfall estimate does not give good results in this particular spell. The reasons for this anomaly have been postulated.

Coso Range rock drawings are a central subject and focus for debates positing alternative meanings and agents responsible for animal depictions in Great Basin prehistoric rock art. We present new evidence offering a middle ground between the divergent views of the ‘hunting religion, increase rites and overkill’ and the ‘shaman, visions and rain-making’ models. We argue that rock-art images, in general, possess multivocality and manifest imbricated conceptual metaphors operating on a variety of scales simultaneously. We recognize that Coso pictures, in one sense, metaphorically represent increase and renewal, human and animal fertility, and game animal magnification. Evidence for that perspective is presented including Coso bighorn with up-raised tails, ‘spirit arrows’, animals giving birth, those that appear pregnant, and an abundance of animals evidencing vitality and movement. Ritually adept shamans also appear to have often been the religious specialists or agents responsible for Coso rock art and the sources for fashioning these images were frequently visionary experiences.

As a common disease of concrete structure in engineering, cracks mainly lead to durability problems such as steel corrosion, rain erosion, and protection layer peeling, and then the building gets destroyed. In order to detect the cracks of concrete structure in time, the bending test of steel fiber reinforced concrete is carried out, and the pictures of concrete cracks are obtained. Furthermore, the crack database is expanded by the migration learning method and the crack database is shared on the Baidu online disk. Finally, a concrete crack identification model based on YOLOv4 and Mask R-CNN is established. In addition, the improved Mask R-CNN method is proposed in order to improve the prediction accuracy based on the Mask R-CNN. The results show that the average prediction accuracy of concrete crack identification is 82.60% based on the YOLO v4 method. The average prediction accuracy of concrete crack identification is 90.44% based on the Mask R-CNN method. The average prediction accuracy of concrete crack identification is 96.09% based on the improved Mask R-CNN method.

Treatment on the exposed surface to the environmental attack was studied based on biopolymer coating from waste cooking oil doped with a superhydrophilic filler of Titanium Dioxide (TiO2), known as TOP. TOP was found to affect the physical properties of the coated concrete surface in a systematic way. Contact angle measurements are interpreted with respect to nanoand micro-features existing on the surface of the water repellent superhydrophilic filler filled bio-polymer composite coating. The smooth coated surfaces of polymer filled or doped with superhydrophobic filler shows the systematic increasing static Waste Contact Angle, WCA (θst) and revealed that polymer filled superhydrophobic fillers by only 2.0 % shows the ability to form superhydrophobicity property. Scanning Electron Microscope (SEM) pictures revealed the difference between the concrete surface roughness of concrete biopolymer with and without TOP coating is to provide self-cleaning concrete biopolymer coating based on two principal ways: (1) the development of surface coating of semiconducting photocatalytic superhydrophilic. (2) If such a superhydrophilic is illuminated by light, then grease, dirt and organic contaminants will be decomposed and can easily be swept away by rain.

The aim of this research is to discover the bond of entropy and the experience of video game immersion, using an Interpretative Phenomenological Analysis (IPA) to interpret the immersive experiences of players and how this bond of entropy and immersion could be transferred on other immersive technologies. The experiment was conducted on a selection of low-entropy scenes in three video games belonging to the genre of interactive drama. Six players were selected as the sample group for this research, based on their playthrough experiences of the games Heavy Rain (2010), Until Dawn (2015) and Dark Pictures Anthology: Man of Medan (2019) on the PlayStation platform. By monitoring the levels of entropy and immersion during their playthroughs, this research explores the potential of transferring immersion through the use of entropy from digital games to other immersive technologies. According to the research highlights and through data interpretation, entropy is found to be immensely influential upon achieving and maintaining narrative, physical and emotional immersion, and its effect could be further applied to other immersive technologies sharing a common ground with digital games, which features are further examined in finer detail in the current research.

The development of a lightweight composite (LC) based on Portland cement concrete with waste lightweight aggregate (WLA) additive was carried out to improve the sustainability and environmental impact and to offer potential cost savings without sacrificing strength. Treatment of the surface of the LC exposed to environmental attack by coating with biopolymer based on waste cooking oil doped with titanium dioxide photocatalysis (TOP) with superhydrophilic property was found to affect the mechanical properties of the LC in a systematic way. The results of compressive strength showed that the composite achieved the minimum required strength for lightweight construction materials of 17.2 MPa. Scratch resistance measurements showed that the highest percentages loading of superhydrophilic particles (up to 2.5% of biomonomer weight) for LC's surface coating gave the highest scratch resistance while the uncoated sample showed the least resistances. Scanning electron microscope (SEM) pictures revealed the difference between the surface roughness for LC with and without TOP coating. TOP is also formulated to provide self-cleaning LC surfaces based on two principal ways: (1) the development by coating the LC with a photocatalytic superhydrophilic, (2) if such a superhydrophilic is illuminated by light, the grease, dirt, and organic contaminants will be decomposed and can easily be swept away by rain.

Abstract Weather mapping began in the nineteenth century when telegraphs began sending simultaneous observations of conditions at the surface of Earth to weather stations around the world. Indicating the complexity of the clouds and weather seen at a site needed a common naming system and simple symbols that were independent of language, since telegraph signals crossed international borders. The first symbols representing clouds were abstracted and stylized versions of their artistic representations in naturalistic drawings and paintings. By the end of the nineteenth century, however, photography began to replace hand-drawn illustrations. Before the advent of color film, black and white photographs were sometimes even reproduced in colored inks using new mechanical printing processes. Nineteenth-century meteorologists developed symbols for various cloud types in the form of simple lines and curves suggestive of the pictures. In contrast, weather symbols (for rain, snow, fog, hail, etc.) were drawn largely from a lexicon of nonalphabetic written symbols, such as punctuation marks. Skilled map plotters used these simple symbols, suggestive of complex weather and clouds, to transfer telegraph and Teletype codes to visually meaningful hand-produced maps. The craft of manual weather map plotting reached an apex in the 1940s–60s. With advances in digital and satellite technology and automation of surface weather observations, the symbols used in traditional weather mapping have largely disappeared from daily use.

Ranching in the 1990s involves vivid word pictures with emotions, learning, a bit of humor, and fierce independence, explained Connie, as students and resource specialists sat on hay bales in a small barn on the high desert in central Oregon. Rangeland Resource students listened, a high school English teacher listened, an Extension horticultural specialist listened, and a Bureau of Land Management ecologist listened along with the professor. A wagon wheel stood near a rusty bucket of sagebrush and bunchgrass. Doc contributed short stories, a few facts, and his perspective of the same events. As she continued, Connie looked toward Doc and wondered whether her story was pitched at about the right level of emotion; was she effectively describing their ranching experience in the 1990s? He smiled under a large grey cowboy hat as his boot rested on the wagon wheel. Everyone felt the tension. Inviting environmental advocates to their ranch … was this wise?Many experiences later, Doc says they have regained independence through collaborative learning with urban dwellers and consumers of their beef products. They welcome people with open minds toward learning. Their vision includes cattle, fish, and wildlife; the 7 inches of rain or snow that falls in winter and must be captured to sustain fish and urban dwellers in August; and sharing beliefs and values about the landscape while fish, grass, and ranchers survive.

Railway vision is an important image processing application in which pictures taken from the front of a train are used to support operational control and inspect wayside facilities. We evaluated picture-taking systems using a space and picture model - the imaginary tunnel model - in which railway space is modeled as an imaginary rectangular tunnel including a construction gauge. Position criteria and camera direction are studied based on the visible tunnel zone. We also estimated position and direction based on rail loci in camera pictures.

Abstract. Detailed characterization and classification of precipitation is an important task in atmospheric research. Line scanning 2-D video disdrometer devices are well established for rain observations. The two orthogonal views taken of each hydrometeor passing the sensitive area of the instrument qualify these devices especially for detailed characterization of nonsymmetric solid hydrometeors. However, in case of solid precipitation, problems related to the matching algorithm have to be considered and the user must be aware of the limited spatial resolution when size and shape descriptors are analyzed. Clarifying the potential of 2-D video disdrometers in deriving size, velocity and shape parameters from single recorded pictures is the aim of this work. The need of implementing a matching algorithm suitable for mixed- and solid-phase precipitation is highlighted as an essential step in data evaluation. For this purpose simple reproducible experiments with solid steel spheres and irregularly shaped Styrofoam particles are conducted. Self-consistency of shape parameter measurements is tested in 38 cases of real snowfall. As a result, it was found that reliable size and shape characterization with a relative standard deviation of less than 5 % is only possible for particles larger than 1 mm. For particles between 0.5 and 1.0 mm the relative standard deviation can grow up to 22 % for the volume, 17 % for size parameters and 14 % for shape descriptors. Testing the adapted matching algorithm with a reproducible experiment with Styrofoam particles, a mismatch probability of less than 3 % was found. For shape parameter measurements in case of real solid-phase precipitation, the 2-DVD shows self-consistent behavior.

However, in case of solid precipitation problems related to the matching algorithm have to be considered and the user must be aware of the limited spacial resolution when size and shape descriptors are analyzed. This work has the aim of clarifying the potential of 2-D-video disdrometer technique in deriving size, velocity and shape parameters from single recorded pictures. The need of implementing a matching algorithm suitable for mixed and solid phase precipitation is highlighted as an essential step in data evaluation. For this purpose simple reproducible experiments with solid steel spheres and irregularly shaped styrofoam particles are conducted. Self-consistency of shape parameter measurements is tested in 40 cases of real snow fall. As result it was found, that reliable size and shape characterization with a relative standard deviation of less than 5% is only possible for particles larger than 1 mm. For particles between 0.5 and 1.0 mm the relative standard deviation can grow up to 22% for the volume, 17% for size parameters and 14% for shape descriptors. Testing the adapted matching algorithm with a reproducible experiment with styrofoam particles a mismatch probability of less than 2.5% was found. For shape parameter measurements in case of real solid phase precipitation the 2DVD shows self-consistent behavior.

In recent years, the country has given the green light to the development of augmented reality technology. Various preferential policies have sprung up such as mushrooms after rain, and augmented reality technology has gradually been applied to all aspects of our lives. In terms of cultural relic protection, the research and protection of ancient murals are undoubtedly not the most difficult. In terms of protection, murals are very fragile, and there are many factors that need to be paid attention to, such as air humidity, temperature, microorganisms, and the shedding of mud layers. In terms of research, the study of frescoes requires a lot of careful observation, but exhaled breath or body temperature that researchers get too close to can have unforeseen consequences. Based on this, the article expounds the composition of the augmented reality technology system. Through image recognition, three-dimensional tracking registration, virtual-real combination, and other technologies, the image obtained by the camera is recognized, and then the environment where the mural is located is a virtual scene through three-dimensional tracking technology. We build and finally use the combination of virtual and real technology to make the ancient murals vividly presented in front of us for our researchers to study more conveniently. The use of Gaussian function, SURF algorithm, FREAK algorithm, RANSAC algorithm, and so on to improve the augmented reality technology system makes the presentation of ancient murals more detailed and realistic. After experiments, we came to the conclusion that the ancient murals processed by augmented reality technology are far more detailed and more complete than the pictures taken by ordinary cameras. Processing ancient frescoes is also far less time-consuming than the existing image processors.

Arabian Sea Monsoon Experiment (ARMEX) 2O02 was carried out from mid June to mid August to study the presence of off-shore trough (OST) and embedded vortices. Four cases of heavy rainfall along the west coast (rainfall exceeding 12 cm in 24 hour) of India were recorded on 14-16 June, 20-22 June, 26-28 June and 7-10 August 2002. The heavy rainfal1 event of 26-28 June was due to a low pressure system that moved from Bay of Bengal across Madhya Pradesh to Gujarat and adjoining Rajasthan. The other three heavy rainfall events were associated with the off shore trough and /or off shore vortices.
Of the various sea buoys deployed in the Arabian Sea, only one buoy located off Goa, did give hint of an OST both in strong and weak wind conditions. However, surface wind data from other buoys and QSCAT surface wind did not always support the presence of OST. The indications were very subtle and it was found difficult to observe them on the NCMRWF (National Centre for Medium Range Weather Forecasting) analysis or forecast charts. In the present study it has been observed that off shore trough may be observed in weak as well as strong monsoon conditions. However, heavy rainfall events were noticed only when the monsoon current is strong both in the Arabian Sea as well as Bay of Bengal in association with some synoptic systems. In addition, an east-west shear line in wind flow pattern extending from lower to middle or upper tropospheric levels and joining the circulation features in the Arabian Sea and Bay of Bengal has been noticed in all cases of heavy rainfall events. Meso-scale vortices/organized convection systems were also identified during heavy rainfall events on the basis of cloud features noticed in the satellite pictures and TRMM rain rate patterns.

Rainfall-induced landslides pose a significant threat to human life, destroy highways and railways, and cause farmland degradation in the Loess Plateau. From 19 June 2013 to 26 July 2013, continuous and heavy rainfall events occurred in the Tianshui area, Gansu Province. This strong rainfall process included four short-term serious rainfall events and long-term intermittent rainfall, triggering many shallow loess landslides. To improve our understanding of this rainfall process as the triggering mechanism of the loess landslides, we conducted the physical-based spatiotemporal prediction of rainfall-induced landslides. By utilizing precipitation data recorded every 12 h from the rain gauge stations and 51 soil samples from within a 50 km radius of the study area, we predicted 1000 physical-based model-calculated pictures of potential landslides, and the slope failure probability (Pf) of the study area was obtained by Monte Carlo simulations. The model was validated by the actual landslide data of the 2013 heavy rainfall event, and the effects of the precipitation process and the trigger mechanism on the landslides were discussed. The results showed that the fourth rainfall event had the best prediction ability, while the third event had the second-best prediction ability. There was a solid linear link between the antecedent precipitation (Pa) and the predicted landslide area (Pls) based on the fitting relationship, indicating that antecedent rainfall may play a significant role in the occurrence of landslides in the region. By comparing the distribution of the predicted results of the four heavy rainfall events with the actual landslide, we observed that the first two rainfall processes may not have been the main reason for slope failure, contributing only to prepare for the landslides in the later period. The superposition of the fourth and third rainfall events finally determined the spatial distribution characteristics of the landslide induced by the 2013 heavy rainfall event.

Autonomous surface vehicles (ASVs) are becoming more and more popular for performing hydrographic and navigational tasks. One of the key aspects of autonomous navigation is the need to avoid collisions with other objects, including shore structures. During a mission, an ASV should be able to automatically detect obstacles and perform suitable maneuvers. This situation also arises in near-coastal areas, where shore structures like berths or moored vessels can be encountered. On the other hand, detection of coastal structures may also be helpful for berthing operations. An ASV can be launched and moored automatically only if it can detect obstacles in its vicinity. One commonly used method for target detection by ASVs involves the use of laser rangefinders. The main disadvantage of this approach is that such systems perform poorly in conditions with bad visibility, such as in fog or heavy rain. Therefore, alternative methods need to be sought. An innovative approach to this task is presented in this paper, which describes the use of automotive three-dimensional radar on a floating platform. The goal of the study was to assess target detection possibilities based on a comparison with photogrammetric images obtained by an unmanned aerial vehicle (UAV). The scenarios considered focused on analyzing the possibility of detecting shore structures like berths, wooden jetties, and small houses, as well as natural objects like trees or other kinds of vegetation. The recording from the radar was integrated into a single complex radar image of shore targets. It was then compared with an orthophotomap prepared from AUV camera pictures, as well as with a map based on traditional land surveys. The possibility and accuracy of detection for various types of shore structure were statistically assessed. The results show good potential for the proposed approach—in general, objects can be detected using the radar—although there is a need for development of further signal processing algorithms.

A detailed description of the forests of the northern and southern macroslopes of western part of the West Sayan Ridge has been performed and differences in their forest vegetation have been analyzed.
Along the West Sayan Ridge watershed, the important botanical and geographical boundary of the Altai-Sayan Mountains occurs. Its northern macroslope belongs to the humid bioclimatic sector; bioclimatic conditions throughout the southern macroslope vary in its different parts: the central and eastern parts are resided in the semihumid sector, while the western one is settled in the «rain shadow», where vegetation is similar to the semiarid sector one. The West Sayan background vegetation type is forest.
The work is based on 120 complete geobotanical relevés made by the authors in 2019 using standard methods on test plots of 20 × 20 m. These plots had been uniformly distributed on a 300-kilometer transect crossing the northern and southern macroslopes of West Sayan’s western part. After all, 9 basic units of forest communities have been revealed, 6 of them are found to be altitudinal zone forests. These plant community positions in ecological-phytocenotic and floristic classification hierarchy have been ascertained. The altitudinal allocation and areas of altitudinal zone forests have been characterized and analyzed; the scheme of altitudinal zonation has been specified; the pictures in the text illustrate those results.
In West Sayan’s western part, the northern and southern macroslopes are shown to have different altitudinal zone boundary marks and a different set of forest communities: six types of forests follow each other from north to south throughout 300 km. The significant hierarchical level of syntaxonomic differences of altitudinal zone forests on northern and southern macroslopes supports the presence of a bioclimatic barrier. In ecological-phytocenotic classification hierarchy these differences are reflected by the rank of classes of formations (deciduous, dark coniferous, and light coniferous forests substitute each other); in floristic classification hierarchy – the rank of classes (the forests of Brachypodio–Betuletea, Asaro–Abitetea, Vaccinio–Piceetea, and Rhytidio–Laricetea substitute each other from north to south).

This study aimed to find out whether the PITR test can be used as a psychological test tool to evaluate the anger expression and perceived stress response of delinquent adolescents. The subjects of the study were 223 vocational training youths located in G city, and the study tools were a person in the rain (PITR) picture test, anger expression checklist, and perceived stress checklist. For data analysis, independent sample t-test was performed by using SPSS 25.0. The research results are as follows. First, in the response characteristics of the person in the rain (PITR) picture test for the anger expression of delinquent youths, significant differences are confirmed in the amount and intensity of rain, the intensity of wind, and the number of lightning. And in the response of coping resources, significant differences were found in the number of direct protection, adequacy of indirect protection, facial expression, and overall figure. Second, in the response characteristics of the person in the rain (PITR) picture test for the perceived stress of delinquent youths, meaningful differences resulted from the amount of rain, the strength of wind, the relationship between lightning and people, and the relationship between people and puddles. In response to coping resources, there are significant differences in the appropriateness of direct protection, the appropriateness of indirect protection, facial expression, and stroke. Based on the above research results, we could verify that the person in the rain (PITR) picture test is useful as a tool to evaluate anger expression and perceived stress in juvenile delinquents.

Severe floods/flash floods ravaged the States of Jammu& Kashmir, Haryana, Himachal Pradesh and Punjab during, (i) 2nd half of July and last half of August 1988. and (ii) 4th week of September 1988. They took place when heavy rains occurred in these States due to the interaction of mid-latitude westerly troughs with the monsoon pulses In the form of equatorial zones of maximum cloudiness (EZMC), located south of 20 N. Satellite pictures and synoptic charts suggest that:
(a) The systems which formed in July-August 1988 were fed by moisture mainly from the Arabian Sea and had tropical characteristic, and
(b) The systems which formed in SejJtember.198.8 had their moisture supply both from the Arabian Sea and the Bay of Bengal and were extra-tropical in character..
The paper describes two of these events in detail. The satellite picture3 show cloud formation resulting in heavy rains.

Abstract. Disaster-relevant authorities could make uninformed decisions due to the lack of a clear picture of urban resilience to adverse natural events. Previous studies have seldom examined the near-real-time human dynamics, which are critical to disaster emergency response and mitigation, in response to the development and evolution of mild and frequent rainfall events. In this study, we used the aggregated Tencent location request (TLR) data to examine the variations in collective human activities in response to rainfall in 346 cities in China. Then two resilience metrics, rainfall threshold and response sensitivity, were introduced to report a comprehensive study of the urban resilience to rainfall across mainland China. Our results show that, on average, a 1 mm increase in rainfall intensity is associated with a 0.49 % increase in human activity anomalies. In the cities of northwestern and southeastern China, human activity anomalies are affected more by rainfall intensity and rainfall duration, respectively. Our results highlight the unequal urban resilience to rainfall across China, showing current heavy-rain-warning standards underestimate the impacts of heavy rains on residents in the northwestern arid region and the central underdeveloped areas and overestimate impacts on residents in the southeastern coastal area. An overhaul of current heavy-rain-alert standards is therefore needed to better serve the residents in our study area.

Wheelsets are among the key components of a rail vehicle. Their task is to guide the vehicle on the track. Any damage or wear may lead to derailment and cause a crash that may cost lives of hundreds of people. Therefore, a significant problem in the designing of wheelsets is the aim of the reduction of the excessive wear of wheelsets during operation. Wear tests of wheelsets under real working conditions are hindered due to their dimensions, the cost of construction of an appropriate testing station, and technological difficulties associated with proper disassembly of the wheel from the axle, which would not lead to the impairment of the overall picture of wear. The article discusses the methodology of a study of the fretting wear of the wheel/axle interference fit model of a wheelset. Thanks to the application of the appropriate criteria of the similarity of the model to the real object, the wear pictures developed may be referred to the wheelset wheel-axle clamped joint.

The article analyzes models of metaphorical description of sounds that are relevant to M. Vinhranovsky’s individual poetic picture of the world. It is determined that the most productive type of audio metaphorization is related to the verbalization of associative sound-to-nature relationships. Its relevance is determined by the collective (secured by verbal tradition) and individual (author) experience of perceiving objects of national space, such as river, sky, water, forest, grove, trees, as well as related phenomena of nature (wind, storm, thunder, rain). and living things (birds, animals, insects). The persistence of associations in the poetic texts motivated by this experience has been consistently confirmed. The collective and individual experience of perception of the phenomena of the nature of rain, thunderstorm, rain, wind, water motivates the active use of «sound» verbs, which metaphorize the various actions and intensity of manifestation of these phenomena. The stylistic performance of common linguistic formulas with stylistically neutral verbs – carriers of the archives of ‘sounds of nature’ is traced. It is proved that an important fragment of the sound definition of the world in the national linguistic-poetic practice and in the idyllic style of M. Vinhranovsky as its symbolic fragment is the image of “silence”. Updating the “zero” manifestation of audio semantics, it creates a semantic opposition to images with the seven “sound”. The aesthetic unfolding of the image of silence in various structural metaphorical structures: verbal predicative, verbal object, oxymoronic, tautological is attested. Analyzed metaphors confirm that the aesthetized verbalization of sound impressions is one of the dominants of M. Vinhranovsky’s individual poetic phrase, in which the metaphors with the seven ‘sound’ are indisputable artistic dominants.

Intisari Beberapa penelitian terkait kejadian hujan menggunakan beberapa jenis alat seperti Micro Rain Radar (MRR) dan Disdrometer. Kombinasi kedua instrument tersebut dapat memberikan gambaran yang lebih komprehensif mengenai kejadian hujan mulai dari lapisan atas atmosfer hingga permukaan. Penelitian ini mengamati beberapa kejadian hujan pada puncak musim hujan tahun 2017 dan pergantian tahun 2019/2020 di Kawasan Puspiptek Serpong, Tangerang Selatan dengan menggunakan instrumen MRR dan Disdrometer untuk mengetahui karakteristik distribusi ukuran butir air hujan. Hasil penelitian ini menunjukkan pola sebaran butir air hujan yang berbeda, antara kejadian hujan dengan intensitas sangat lebat dan sangat ringan hingga lebat, baik pada lapisan atas atmosfer maupun permukaan. Selain itu, hasil penelitian ini menunjukkan bahwa kejadian hujan sangat lebat berasal dari kumpulan awan konvektif dengan durasi hujan selama 15-60 menit. Sedangkan, kejadian hujan ringan hingga sedang pada umumnya berasal dari kumpulan awan nimbostratus di level menengah atmosfer dengan durasi hujan sekitar 2-3 jam. Abstract Several studies used some equipment types to observe rain events, such as the Micro Rain Radar (MRR) and Disdrometer. Combining the two can provide a more comprehensive picture of rain events from the upper atmosphere to the surface. This study observed several rain events at the peak of the rainy season in 2017 and the turn of the year 2019/2020 in the Puspiptek Serpong Area, South Tangerang, using MRR and Disdrometer instruments to determine the characteristics of the droplet size distribution. This study's results indicate a different droplet size distribution pattern, between the incidence of rain with very heavy intensity and very light to dense, both in the upper atmosphere and surface. Besides, this study's results indicate that the very heavy rain events come from convective clouds with a 15-60 minutes rain duration. Meanwhile, light to moderate rain events generally come from a group of nimbostratus clouds in the medium-level atmosphere with a rain duration of roundabout 2-3 hours.

Abstract. The theory of scale similarity and breakdown coefficients is applied here to intermittent rainfall data consisting of time series and spatial rain fields. The probability distributions (pdf) of the logarithm of the breakdown coefficients are the principal descriptor used. Rain fields are distinguished as being either multiscaling or multiaffine depending on whether the pdfs of breakdown coefficients are scale similar or scale dependent, respectively. Parameter estimation techniques are developed which are applicable to both multiscaling and multiaffine fields. The scale parameter (width), σ, of the pdfs of the log-breakdown coefficients is a measure of the intermittency of a field. For multiaffine fields, this scale parameter is found to increase with scale in a power-law fashion consistent with a bounded-cascade picture of rainfall modelling. The resulting power-law exponent, H, is indicative of the smoothness of the field. Some details of breakdown coefficient analysis are addressed and a theoretical link between this analysis and moment scaling analysis is also presented. Breakdown coefficient properties of cascades are also investigated in the context of parameter estimation for modelling purposes.

Abstract. This review discusses published studies of heavy rainfall events over the Mediterranean Basin, combining them in a more general picture of the dynamic and thermodynamic factors and processes that produce heavy rain storms. It distinguishes the western and eastern Mediterranean in order to point out specific regional peculiarities. The crucial moisture for developing intensive convection over these regions can be originated not only from the adjacent Mediterranean Sea but also from distant upwind sources. Transport from remote sources is usually in the mid-tropospheric layers and associated with specific features and patterns of the larger-scale circulations. The synoptic systems (tropical and extratropical) that account for most of the major extreme precipitation events and the coupling of circulation and extreme rainfall patterns are presented. Heavy rainfall over the Mediterranean Basin is caused at times in concert by several atmospheric processes working at different atmospheric scales, such as local convection, upper synoptic-scale-level troughs, and mesoscale convective systems. Under tropical air-mass intrusions, convection generated by static instability seems to play a more important role than synoptic-scale vertical motions. Locally, the occurrence of torrential rains and their intensity is dependent on factors such as temperature profiles and implied instability, atmospheric moisture, and lower-level convergence.

The approach used in this study is a qualitative approach with the source data of this research is a text in the form of Tere Liye's Rain novel. Data collection techniques in this research is the technique of reading and writing. The result of this research is to know the potential hypogame of the disaster that happened in 2015 and the actual hipogram of novel Rain that is novel which ever published previously called Rindu. The meaning of "rain" in Tere Liye's Rain novel based on heuristic readings means that rain is closely related to natural disasters, while the meaning of "rain" in the novel Rain based on hermeneutic readings results in meaning that rain can cause feelings to a person depending on the situation they are experiencing that. Based on the role of the symbol "rain" in the formation of meaning and aesthetics it shows the existence of attachment between the formation of meaning and beauty of a text. Thus, the results of this analysis can be used as a knowledge and can be used as a picture of life in the world to think about various posisif and negative things related to the rain. Basically rain plays an important role in everyday life.

Abstract Background. Few data are available concerning incidence, clinical picture, and prognosis for pancreatic metastases of small cell lung carcinoma. In this paper we review the related literature available in English language. Conclusions. Although pancreatic metastases are generally asymptomatic, they can rarely produce clinical symptoms or functional abnormalities. The widespread use of multi-detector computerised tomography (CT) in contemporary medical practice has led to an increased detection of pancreatic metastases in oncology patients. Tissue diagnosis is imperative because radiological techniques alone are incapable of differentiating them from primary pancreatic tumours. Pancreatic metastases occur in the relative end stage of small cell lung cancer. The main complications of these lesions, although rare, are acute pancreatitis and obstructive jaundice. Early chemotherapy can provide a survival benefit even in patients with mild acute pancreatitis or extrahepatic biliary obstruction.

Limitations of observational data such as insufficient data length, incomplete, and uneven station distribution make it difficult to analyze and predict rain, so it requires supporting instruments such as satellites to provide a better and broader picture of rainfall distribution. However, it is necessary to test the accuracy of satellite data because the resolution and conditions of each region are different. This research aims to validate IMERG rain data against observation data in the 2015 El Nino period using observation rainfall data from BMKG Negara and IMERG data from GPM satellite at 12 rain points in Bali Province. The analytical method used is quantitative statistics, the calculation of errors and correlations and the comparison of the spatial pattern of the two data. The results of the analysis of the spatial pattern of the IMERG data show that, there was a decrease in rainfall from May to July, but the rainfall increased into August, and again experienced a decline entering the months of September to December where the same pattern was also shown from the results of the spatial pattern analysis on the Observation data. The decrease in rainfall in the May-December 2015 period was a strong El Nino effect as evidenced by the results of the correlation analysis of the SOI index on rainfall which showed a fairly strong correlation value, namely 0.55.The validation of IMERG data on monthly observation data showed that the average correlation was sufficient strong is 0.42 and analysis per rain post shows a weak correlation namely 0.31, which means that data IMERG is not yet accurate as an alternative to the observation rainfall data in Bali Province.

Abstract Background. Thoracobiliary fistulas are pathological communications between the biliary tract and the bronchial tree (bronchobiliary fistulas) or the biliary tract and the pleural space (pleurobiliary fistulas). Review of the literature. We have reviewed aetiology, pathogenesis, predilection formation points, the clinical picture, diagnostic possibilities, and therapeutic options for thoracobiliary fistulas. Case report. A patient with an iatrogenic bronchobiliary fistula which developed after radiofrequency ablation of a colorectal carcinoma metastasis of the liver is present. We also describe the closure of the bronchobiliary fistula with the greater omentum as a possible manner of fistula closure, which was not reported previously according to the knowledge of the authors. Conclusions. Newer papers report of successful non-surgical therapy, although the bulk of the literature advocates surgical therapy. Fistula closure with the greater omentum is a possible method of the thoracobiliary fistula treatment.

The aim of this paper is to indicate the importance of the metaphorical terminology and verbal description of music in education and performance due to inevitable role of emotions and embodiment in music experience. Metaphorical music terminology should follow the interpretative maturity, such as for the term scherzo, which would be joke for younger, but forced joke or all but prank for older musicians. For music beginners we can use extramusical verbal symbols: the pulse is represented as the stickman; major with the symbol of sun and minor with the symbol of rain; sequencing is presented with the picture of stairs; the picture of butterfly implies image-schematicity in interpreting the wave melodic contour; children understood duple meter through the picture of a soldier, while triple meter appreciated through the picture of a ballerina; staccato is experienced as a movement, but also as a visual and auditory metaphor. Multimodality plays an important role in music education, because it implies the integration of movement, sound, picture and verbal metaphors. Therefore, the musical experience is described and performance interpreted by following the direction from the emotional sound experience to its cognitive processing. Mul- timodal approach would increase associative thinking and enlarge individual associations on musical terms, which gives a better understanding of music and widens perspective in music education.
