Abstract:

A colour may have a different appearance under different viewing conditions. This causes many problems in the colour reproduction industry. Thus the importance of prediction of colour appearance has arisen. In this study, a mathematical model to predict colour appearance was developed based on the investigation of the changes of colour appearance under a wide range of media and viewing conditions. The media studied included large cut-sheet transparency films, 35mm projected slides, reflection samples and monitor colours. The viewing conditions varied were light source, luminance level and view

Reliable colour constancy by industry for colour conducted to quantify metamerism. and metamerism indices are highly desired quality control. Two experiments were the degree of colour constancy and In the colour constancy experiment, 240 wool samples were prepared and scaled using a magnitude estimation method by a panel of 5 experienced observers under sources D65, A and TL84. 2 corresponding data sets derived from the experimental results were used to test various chromatic adaptation transforms. The results clearly show that the BFD transform gave the most precise prediction than the other

Abstract:

Colours play an important role in our everyday life. Yet, it is something that we might not pay too much attention to, it is just there, even if we may have our favourite colours and likewise. However, sometimes the colours have a very specific meaning and is a medium of communication. One example of this is air traffic control systems as the one used in Sweden, Denmark, Austria, Ireland, and Croatia. However, despite using the same system, all but Denmark and Sweden use different colour schemes in the human computer interface of the radar screens. A decision was taken within the common organi

Abstract:

The colour of guppies (Poecilia reticulata) evolves as a compromise between sexual selection (favouring conspicuousness) and natural selection (favouring crypsis). However, guppies live in a variety of habitats and with a variety of predators and consequently in a variety of selective environments. I investigated how habitat and predator's visual systems affect the evolution of colour. I used regressions to assess the importance of habitat features on the evolution of colour for 29 guppy populations. I then quantified the colour of guppies living in the presence and absence of two predators. T

Male subjects (n = 90) were assigned to one of 15 treatment conditions (n = 6) as determined by the colour (blue/green, red or white) and intensity (0.1; 0.4; 1.6; 6.4 and 25.6 cd/m²) of the pre-adaptation stimuli.

Abstract:

Predators select for defensive adaptations, such as stings, toxins, and camouflage color patterns. Madtoms, Noturus, are diminutive catfishes with dorsal and pectoral stings. Thirteen of the 25 nominal species have serrated spines in the pectoral sting and a contrasting pigment pattern. Behavior of two saddled species, N. miurus and N. hildebrandi, and one uniformly colored species, N. leptacanthus, was investigated to test if the pigment pattern is camouflage. Saddle spacing and crypticity of the saddled species were measured against various substrates and were found to be unevenly spac

Alpine and sub-alpine regions were long considered free of Phytophthora species, especially Phytophthora cinnamomi due to restrictions on their growth from low temperatures. However, P. cinnamomi was isolated from a sub-alpine area ‘Barrington Tops National Park’ in the 1990s. Subsequent Australia wide surveys detected 68 Phytophthora species in Australia. Of these, 33 Phytophthora species, including P. cinnamomi, were detected in the alpine and sub-alpine areas on Kosciuszko National Park (KNP) alone. This suggested that Phytophthora species had adapted to cold environments. This project inve

Between individual behavioral variation has been described in nearly every animal taxa where it has been measured.

Despite a recent push to better understand the origins and consequences of behavioral syndromes, there still is no cohesive framework that describes this phenomenon. Here, I develop a social insect species into a model for measuring and testing behavioral syndromes at a new level of biological organization; the colony.

碩士<br>國立成功大學<br>工業設計學系<br>102<br>Smart devices are becoming increasingly important these years and human beings spent more and more time on electronic screen. Screen acts as a input and output interface at the same time, use of color on screen become a important topic too. There are two experiments in this study, the first experiment records the reaction time of participants before color adaptation, the second experiment records the reaction time of the same task after color adaptation. Color samples used in this study include three primary colors and three complex colors, size of the stimulus

博士<br>國立成功大學<br>工業設計學系<br>105<br>This study explored, under two different illumination conditions (normal daylight at D65 and low illumination), how chromatic adaptation affected the legibility, texture recognition of background threshold and then found the color threshold or texture that would not affect each other for those with color vision deficiency (CVD) and those who had normal color vision (NCV). The study mainly used the basic screen colors such as red, green, cyan and yellow and the Landolt ring system, associated with vision measurement, and formed them into experiment stimulus wit

Abstract:

<p>One of the major goals of evolutionary biology is understanding the process of species formation. There is particular interest in how selection can favor species formation through the process of reinforcement. When two diverging taxa produce maladaptive hybrids, selection will favor greater reproductive isolation between the taxa. Reinforcement often results in a pattern of reproductive character displacement, which is defined as two species having greater reproductive isolation in sympatry then in allopatry. Floral-color divergence in the native Texas wildflower, Phlox drummondii, cons

Abstract:

<p>Examining the genetic basis across repeated origins of the same phenotypic adaptation allows us to address several questions pertaining to the genetic basis of adaptation. First, whether the genes and types of mutations that are involved in adaptation are predictable. Second, whether the underlying genetic changes can constrain future evolutionary trajectories. Here, I have focused on the genetics of blue to red flower color shifts, an adaptive shift that has repeatedly occurred across angiosperms. First, I review the literature and determine the relative contribution of functional vs.

Abstract:

Apis mellifera iberiensis is a honey bee subspecies native to the Iberian Peninsula. Its adaptive potential allows the development of several phenotypes depending on the environment. The aim of this study is to understand to what extent there is local adaptation in this subspecies of Iberian Peninsula, which has proved to be highly diverse and complex at the genetic level. To this end, we established two experimental apiaries at the latitudinal extremes of Portugal (Gimonde, in the Northeast, and Zavial, in the Southwestern).

Abstract:

Multiculturalism and the merging of local communities with immigrants demands glocal policies in various sectors—especially in education. In order to successfully integrate immigrants, language acquisition is oftentimes the first initiative educators and politicians regard as one of the most essential attributes for successful and prompt integration. However, language acquisition cannot be separated from the need to bridge communities and their different values, tradition, ideologies, and identities based on their cultural heritages and religious affiliations. In order to properly respond to n

Dans cette thèse, nous abordons le contrôle moteur du mouvement du coude à travers deux approches expérimentales : une première étude psychophysique a été effectuée chez les sujets humains, et une seconde implique des enregistrements neurophysiologiques chez le singe. Nous avons recensé plusieurs aspects non résolus jusqu’à présent dans l’apprentissage moteur, particulièrement concernant l’interférence survenant lors de l’adaptation à deux ou plusieurs champs de force anti-corrélés. Nous avons conçu un paradigme où des stimuli de couleur aident les sujets à prédire la nature du champ de force
