Abstract Safety of satellites as well spacecrafts during space missions is a primary objective to preserve the physical and virtual assets onboard. Whipple shields belong class protective equipment provided on surface satellites, sustain impacts from ultra-high speed debris, which can otherwise cause considerable damage corresponding structures. Recent works whipple are focussed determining res...

The resource-intensive automotive industry offers great potential to avoid waste through new circular business models. However, these models require technical innovations that enable the rapid dismantling of add-on parts. In this paper, we design mechanical interfaces fast and non-destructive while still fulfilling all requirements develop a general model for evaluation disassembly capability. ...

In this study, the effects of surface roughness differences vehicle coating materials (paint, paste, special applications, etc.) on aerodynamic drag coefficient were inves-tigated using finite element method. For this, forces and aerody-namic coefficients for speeds between 40-150 km/hours calculated a 1/20 scale designed by package program defining body parts front-rear window separately assig...

Children often refer to things ambiguously but learn not to from responding to clarification requests. We review and explore this learning process here. In Study 1, eighty-four 2- and 4-year-olds were tested for their ability to request stickers from either (a) a small array with one dissimilar distracter or (b) a large array containing similar distracters. When children made ambiguous requests...

A popular bumper sticker states: “There is no cloud. It’s just someone else’s computer.” Despite the loss of control that comes with its use, critical records are increasingly being entrusted to the cloud, generating ever-growing concern about the privacy and security of those records. Ultimately, privacy and security constitute an attempt to balance competing needs: privacy balances the need t...

One of the most interesting aspects of sports fans is their degree of involvement and affiliation with their favorite sports team. Indeed, perusal of the popular press suggests that sports fans reveal their connection to a favorite team in interesting ways, including wearing team apparel, displaying bumper stickers on their cars, and engaging in celebratory behaviors that range from fairly pass...
