A new electron monitor unit (MU) calculator program called "eMUc" was developed to provide a convenient electron MU calculation platform for the physics and radiotherapy staff in electron radiotherapy. The program was written using the Microsoft Visual Basic.net framework and has a user-friendly front-end window with the following features: (1) Apart from using the well-known polynomial curvefi...

The Goldberg construction of symmetric cages involves pasting a patch cut out of a regular tiling onto the faces of a Platonic host polyhedron, resulting in a cage with the same symmetry as the host. For example, cutting equilateral triangular patches from a 6.6.6 tiling of hexagons and pasting them onto the full triangular faces of an icosahedron produces icosahedral fullerene cages. Here we s...

Descriptions of manual function in nonhuman primates have largely focused on static precision and power grasping (as first defined by Napier,1956), while identification and description of dynamic manual function are rare and incomplete. Here, we describe several forms of in-hand movements used by chimpanzees (Pan troglodytes) when manipulating small objects. In-hand movements are defined as the...

In this paper we develop a new simple and effective isogeometric analysis for modeling thermal buckling of stiffened laminated composite plates with cutouts using level sets. We employ first order shear deformation theory to approximate the displacement field stiffeners plate. Numerical treatment trimmed objects, such as internal in terms NURBS-based presents several challenges, primarily due n...

Earlier [I], it was shown that certain reinforced holes may be designed for elastic, isotropic plane sheets that do not alter the stress state in the cut sheet, for particular types of planar loading. In this work, this methodology is extended to symmetrically laminated composite plates which are under planar loading, and additionally pure bending moments. Since these two types of loading lead ...
