Target enclosure by autonomous robots is useful formany practical applications, for example, surveillance of disaster sites. Scalability is important for autonomous robots because a larger group is more robust against breakdown, accidents, and failure. However, since the traditional models have discussed only the cases in which minimum number of robots enclose a single target, there has been no...

Recently, an alternative interval approximation F X ( ) for enclosing a factorable function f(x) in a given box X has been suggested. The enclosure is in the form of an affine interval function F X a X B i i i n ( ) = + ∑ =1 where only the additive term B is an interval, the coefficients ai being real numbers. The approximation is applicable to continuously differentiable, continuous and even d...

Literature about entropy generation analysis of a wavy enclosure is scare. In this paper. a FORTRAN cod using an explicit finite-volume method was provided for estimating the entropy production due to the natural convection heat transfer in a cosine wavy absorber solar collector. The volumetric entropy generation terms both the heat transfer term and the friction term were straightly calculated...

Additive manufacturing has become a widely utilized process in industrial, academic, and household applications. Previous studies have demonstrated that non-optimum humidity conditions can adversely impact the print quality of parts printed from plastic filaments by changing their mechanical properties, such as elastic modulus ultimate strength. This study computational fluid dynamics (CFD) app...
