A computational approach to the quantification of animal camouflage
… pressures have led to some astonishing camouflage strategies in the animal kingdom. Cephalopods like cuttlefish and octopus mastered a rather unique skill: they can rapidly adapt the way their skin looks in color, texture and pattern, blending in with their backgrounds. Showing a general …

Camouflage Romance: Same-Gender Romantic Relationship Quality and Effects on Military Commitment
<p>Military life comes with a host of challenges for romantic relationships. Romantic partners withstand the pressures of deployment and geographical relocations (i.e., military transitions) to support their service members’ careers and play a critical role in swaying service members’ decisions to …

Coloration, Camouflage, and Sexual Dichromatism in the Northern Pacific Rattlesnake (Crotalus oreganus)
In some viperid snakes, natural selection has shaped coloration and patterning to match local habitats, and for males to show greater warning coloration than females due to a less sedentary lifestyle. The Northern Pacific Rattlesnake (<em>Crotalus oreganus) </em>is likely the most abundant ambush …

Not all camps have camouflage: gay writing and the great South African dream
I shall be addressing the question of the constitutive importance of sexuality, and specifically of articulations and representations of homosexuality, in the self-defining national imagination of post-apartheid South Africa. I shall be concerned with ways of thinking the representation of …

Using virtual reality to investigate the visual features that determine the effectiveness of disruptive camouflage
Disruptive camouflage (DC) is a strategy by which animals utilise high contrast markings to visually break up their otherwise recognisable shape and prevent detection and possibly recognition. Edge enhancement (EE) is a phenomenon sometimes found alongside disruptive camouflage, where the contrast …

Disruptive dissolution: the ability to naturalize in the landscape
The word camouflage is derived from the 16th century French word camouflet, which translates as a practical joke in the form of a puff of smoke under one’s nose (Hartcup, 1980). As this early ‘definition’ suggests, it is an enigmatic and elusive subject. Although generally perceived as synthetic in …

Training and transfer of training in rapid visual search under high target-background similarity
… participants trained to search for targets on camouflage backgrounds (high target-background similarity) were just as quick to find the camouflaged targets from a different set of images (Boot, Neider & Kramer, 2009). This was achieved in a free viewing paradigm. The unusually robust transfer …

Tests of Adaptive Coloration Hypotheses for Madtom (Notorus) Catfishes (Siluriformes: Ictaluridae)
… 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, …

Microcultures of collaboration: entangled artistic pedagogies for students and educator
… during a contemporary art project called Sonic Camouflage. The off-campus project-based learning environment of Sonic Camouflage was shown to boost and intensify learning for all participants, with an integrated re-energising tri- role for the educator to partake in art, education, and research …

Steering Laws for Pursuit
… laws for a specific pursuit process, motion camouflage with respect to infinity. This type of guidance law renders the baseline (line connecting the pursuer and evader) parallel to a fixed line. In observations of prey pursuit trajectories of echolocating bats, it has been noted that the same …

The function of passive debris cloaking in tiny beetles (Coleoptera: Zopheridae)
… the antipredator adaptations currently known, camouflage has perhaps received the most interest. However, there has been a strong focus on larger animals that reside out in the open, but empirical evidence of camouflage in smaller litter dwelling invertebrates is lacking. Some species in these …

Sculpture as artifice: mimetic form in the environment
Can natural and artificial patterning (camouflage) intersect with organic systems and entropic forces in nature to symbiotically link a sculpture to its environment? Through practice led, theory-based research, studio investigation and field study, I will develop a sculptural earthwork called Mud …

Exploring social camouflaging in adolescents with and without autism
… and that autistic females may be more likely to camouflage than autistic males. However, research in this area is limited to autistic adults and has not typically included neurotypical comparison groups. A better understanding of camouflaging in younger individuals, and how camouflaging may be …

Fractal Modulation and Encryption

Energy conserving privacy enhancing algorithms for resource-constrained devices

Social camouflaging and mental health in adolescence: differences by sex and diagnosis
… Importantly, nonautistic individuals can also camouflage, as autistic traits are distributed throughout the general population. Some studies suggest that autistic females camouflage more than autistic males, and many studies have found that camouflaging is negatively associated with mental …
