Autler-Townes splitting in two-color photoassociation of 6Li

We report on high-resolution two-color photoassociation spectroscopy in the triplet system of magneto-optically trapped 6Li. The absolute transition frequencies have been measured. Strong optical coupling of the bound molecular states has been observed as Autler-Townes splitting in the photoassociation signal. The spontaneous bound-bound transition rate is determined and the molecule formation rate is estimated. The observed lineshapes are in good agreement with the theoretical model.Comment: 5 pages, 4 figures, accepted for publication in Phys. Rev. A (Rapid Communication

Fertilization of rice plants according to the dose of their needs is one of the important things to produce an optimal rice harvest. Giving less or more fertilizer can cause rice plants not to grow optimally and even cause crop failure. The need for fertilizer doses can be determined by changing the color of the rice leaves using the Leaf Color Chart (LCC). However, obstacles in the field are challenging for novice farmers to predict fertilizer needs just by looking at the color of the leaves with the naked eye. The application of information technology is expected to help farmers, especially novice farmers, in measuring the dose of fertilizer needed for rice plants. The technology that will be applied is an electronic device that can detect the color of rice leaves and provide information for users from the measurement results through an android application on a smartphone device. The electronics modules used are the TCS320 color sensor module which functions to detect the color of objects, the Arduino UNO microcontroller module which contains ATMega128 as a data processor, and the Bluetooth module as a communication liaison between the microcontroller device and the android application on the smartphone. The test results show that the built device can function properly. All tested leaves can be classified according to the greenish level of the leaf color

The Ecology of Dynamic Body Color in the Green Anole, \u3cem\u3eAnolis carolinensis\u3c/em\u3e

Organisms capable of physiological body color change can respond rapidly to changes in their social or external environment. Given that color change is often context-dependent, studying the role of color change can provide insights into how different organisms respond to and interact with their immediate environment. Currently there are three main hypotheses which explain the adaptive significance of rapid color change, including camouflage, social signaling, and thermoregulation. Green anoles, Anolis carolinensis, are one such species that use physiological color change to rapidly shift their dorsal body color from bright green to dark brown within seconds. Thus, they may use darkening and lightening of body color to either regulate their body temperature throughout the day, or as a visual signal during intraspecific communication. Previous studies have determined the physiological mechanisms by which color change occurs in green anoles, but few naturalistic studies have determined the ecological role of dynamic color change in anoles, and fewer still have examined how males and female green anoles may differentially use color change. In this thesis, I performed two studies testing two major hypotheses for the evolution of physiological color change. In my first study I examined the relationship between body color and body temperature of green anoles, and whether this varies between the sexes, or among different substrate types. My data showed that while males choose marginally warmer substrates and more exposed perch sites than females, there was no association between body color and body temperature in either sex. In the second study I tested whether body color is used in conjunction with behavioral displays of green anoles, and if this differs between the sexes. My results showed that overall, males are far more likely to be green than females. Further, males and females differ in how they use body color during social displays. In sum, my studies found that body color change is predominantly used in behavioral displays of green anoles, and males and females differ in how they use color during social signaling. My findings also indicate that thermoregulation is likely not a primary reason for body color change in either sex, and color likely plays less of a role in thermoregulation in anoles than previously believed

Coil Gun Turret Control Using A Camera

ABSTRACT --- A conventional weapon usually by pointing to the target aimed by using hands. It is considered less effective and efficient in terms of military service because of spending lots of time to chase the target. So needed a tool to move the weapon automatically. This final project present about object tracking in a weapon and it’s turret, that will be controlled by camera. The camera is used to detect moving targets based on a particular color. In a image sequence consisting of many different objects, accompanied by a different background, this system will be able to distinguish between the target or not. Camera detection is done by taking moving images with color composition that has been determined. Then, The image resolution is resized of the smallest of camera’s resolutions, that is 320x240. Smaller image size are intended for the system’s working to be faster. Capturing image process is use segmentation object process in digital image processing which aims to separate the object region with background. The weapon that will be used, have two degrees of freedom. Maximum 360 degrees rotation in x axis, and maximum 90 degrees in y axis. Both of them using brushed DC motor. At the direction of the y- axis motion required a gear for transmitting power between motor shaft and the shaft, so the shaft is not directly connected to the motor and no distortion. Turret have been designed had four buffers as a solid foundation to bear the entire load. Communication between the camera and weapons carried out by using the cable. Turret will be controlled using the PD control which is expected to reach a position with a quick reference. Key Words: Object tracking, Digital Image Processing, Image sequence, PD (Proposional Deravative) Contro

Специфика индивидуально-авторского стиля создания цветовой сенсорной образности в поэтическом тексте: лингвокультурологический анализ

Sensory perception of the world is the ontological basis of human existence that helps an individual to be oriented in the world. It also helps one to find the path in the most difficult circumstances of social communication. This makes it relevant to pay attention to sensory mechanisms and their functions in various fields of knowledge, from psychology to linguacultural studies. In modern linguistics, the category of sensory imagery is one of the complex phenomena, based on the author’s individual sociocultural experience. This experience is especially vividly realized in a poetic text, which is the highest form of sensory expression. In a poetic text, one can single out an independent block of color information, deliberately embedded in the content by its creators as an additional visual means. At the same time, this functionality of color is determined primarily by the peculiarities of individual author’s style in the creation of sensory visual color imagery.Sensory perception of the world is the ontological basis of human existence that helps an individual to be oriented in the world.

Она же помогает ему ориентироваться и в более сложных обстоятельствах социальной коммуникации. Все это делает актуальным внимание к сенсорным механизмам и их функционированию в самых разных областях знания, от психологии до лингвокультурологии. В современной лингвистике категория сенсорной образности выступает одним из сложных феноменов, в основе своей опирающийся на индивидуальный социокультурный опыт автора. Особенно ярко данный опыт реализуется в поэтическом тексте, представляющим собой наивысшую форму чувственной экспрессии. В таком тексте можно выделить самостоятельный блок информации, передающейся с помощью цвета, сознательно вложенный в содержание его создателями в качестве дополнительного изобразительного средства. При этом подобное функционирование цвета определяется, в первую очередь индивидуально-авторскими особенностями в создании сенсорной зрительно-цветовой образности

The Use of A Feeding Assay to Test the Effects of Visual Color Contrast on Stimulus Visibility in the Lizard Anolis sagrei and the Evolution of Anolis species in the Dominican Republic

Many animals depend on color signals for communication. It has been hypothesized that signals evolve toward maximum visibility against natural backgrounds. Testing this hypothesis requires a way to assess the influence of signal/background color contrast on signal visibility. Most tests such as these rely on training, which can be very time consuming and difficult for some types of animals. We created a method for testing color contrasts using the lizard Anolis sagrei. We colored dead worms using powdered food coloring and placed them on backgrounds of varying colors and luminance. We presented stimuli in pairs that differed in contrast with the background, and determined that most individuals would choose the more visible food item first. We examined the effects of luminance and color contrast on stimulus visibility, and also tested for any inherent bias in preference for specific colors. Finally, we tested the effects of low light conditions on spectral contrast based visibility. We expected low light to reduce the effects of spectral contrast because it is known to elevate color discrimination thresholds. We found that this method is an effective approach to testing signal visibility in an animal that is difficult to study with standard conditioning techniques. We also wanted to see if dewlaps evolved towards maximum visibility in Anolis species in the Dominican Republic. We collected light habitat data, dewlap color data, and body color data on five different species of anoles in the Dominican Republic and compared the data using a tetrahedral perceptual color space program. We found that not only did the background play a role in the evolution of the dewlap color, but also species discrimination was a driving evolutionary factor in Anolis species of the Dominican Republic

The Study of using the banded anilox roller for color matching in flexography

Color matching is an important issue in the flexographic industry today because of many problems related to it. For example, there are few standards of ink and color for spot color printing. Further, there is no standardization in the communication among anilox roller suppliers and their customers concerning the specific cell volume measurement of the anilox roller. This research focused on the study of the use of the banded anilox roller as a tool for color proofing under the assumption that a spot color printed by the flexographic process actually should be produced using a banded anilox roller as a tool for color proofing. The major questions for this study were: 1. How will the anilox cell volume and line screen per inch affect the CIE LAB total color difference (AE) ? 2. Can the same color actually be produced with a AE \u3c 2 (good match) by using the same specification of anilox roller? This research was conducted by printing a spot color with two banded anilox rollers to match the original Pantone color as close as possible and using it for the reference. The data collected from each of the bands was plotted in diagrams to see the effects of cell volume and line screen per inch on the total color difference(AE). In this experiment, two ink color strengths were used. In the second experiment, three anilox rollers were tested. The same specifications were given from the particular band of banded anilox roller derived from the first experiment to give the best color match from the first run. The second experiment was to print the same spot color using the three anilox rollers and banded anilox to deter mine which would give the closest match to the original Pantone color. Samples from each of the anilox rollers were collected and measured for their total color differences (AE) as determined relative to the sample mean of press sheets selected from the second press run of the banded anilox roller. In addition, the same banded anilox from the second press run was used to run again to confirm the result. The press sheets for each of the anilox rollers was evaluated for the degree of color matching to the press sheet printed by the banded anilox from the second press run. The study results show that there is a negative linear relationship between the cell volume (BCM) and the CIE LAB total color difference (AE), and a positive linear relationship between the line screen per inch (LPI) and the CIE LAB total color difference (AE). Ink color strength also has a significant impact on the changing of the AE value. Furthermore, the same color can be produced with AE \u3c 1 ( no difference) by using the same banded anilox roller. However, only one of the three anilox rollers from different suppliers can produce the same color with the CIE LAB total color diffference (AE) \u3c 2

Color-mediated foraging by pollinators: A comparative study of two passionflower butterflies at Lantana camara

Colorful floral signaling and resulting insect foraging behaviors have only been extensively examined in hymenopteran pollinators, especially bees, in comparison to flies, beetles, and butterflies regardless of their ecological importance. Therefore, my study provides novel information by focusing on foraging behaviors of adult passionflower butterflies, Heliconius melpomene and Dryas iulia, to the color changing flowers of Lantana camara. My dissertation which is divided into four chapters, aims to explore various aspects of color mediate foraging in passionflower butterflies by combining observations in the wild with controlled field and laboratory experiments. In the first chapter I reviewed flower color development and pollinators\u27 sensory mechanisms to detect color changes to first elucidate the evolution of communication tactics from the senders (plants), and the detection mechanisms used by receivers (pollinators). In the second chapter I examined the relationship between sexual and foraging color biases of butterflies. In my third chapter I determined how color change associated with reward differences affected pollinator-plant attraction; and for my final chapter I investigated foraging movement patterns as butterflies fed on L. camara plants in their natural habitat. Overall, I presented evidence that indicated the following: 1) L. camara evolved a generalized pollination visitation system based on honest signaling―of reward quantity and quality tied to color changing visual signals acting in consort to produce a billboard effect that was easily perceived and deciphered by both passionflower butterflies; 2) experienced butterflies fed at flowers and were attracted to inflorescences that were of similar color to their wings, however, newly emerged butterflies exhibited different but species specific behaviors; 3) foraging behaviors were subject to change based on light environment, with yellow flower color eliciting feeding responses under blue light (open sky), and red elicited foraging under green light conditions (under forest canopy); 4) butterflies partitioned food resources spatially and temporally from each other, and from aggressive territorial hummingbirds; and 5) butterfly species changed the number of visits to plants, number of plants visited, and time spent foraging in order to successfully coexist with heterospecific competitors that shared the same space and food resource
