Sizes and stiffness variations of actively deformable objects pose significant challenges on the design of compliant constant-force gripper.This paper presents a curved-beam based constant force compliant gripper which is composed of the constant force module, the bistable module, the preloading module and the linear guide.A chocolate chip cookie p
Structural anti-reflective coating and bactericidal surfaces, as well as many other effects, rely on high-aspect-ratio (HAR) micro- and nanostructures, and thus, are of great interest for a wide range of applications.To date, there is no widespread fabrication of dense or isolated HAR nanopillars based on UV nanoimprint lithography (UV-NIL).In addi
Compounding humanitarian and political crises within and across countries have been met with shrinking public resources for coordination, recovery, and mitigation.This resource constrained humanitarian environment presents opportunities for multinational a&d ej-123 corporations to supplement budgets and actively participate in new markets through c
Some populations will cope with human-induced environmental change, and others alphaville clothing will undergo extirpation; understanding the mechanisms that underlie these responses is key to forecasting responses to environmental change.In cases where organisms cannot disperse to track suitable habitats, plastic and evolved responses to environm
One of the most significant consequences of the use of post-conviction DNA testing in the criminal justice system has been the growing recognition that eyewitness identification testimony is simply not as reliable as it was previously considered to be.In approximately 75% of DNA exonerations in the United States, mistaken eyewitness identifications
