Alternate reality games (ARGs) are a promising new approach for increasing student engagement; however, automated methods for analyzing and optimizing game play are non-existent. We captured the player communication generated by a recent STEM-focused ARG that we piloted in a Los Angeles charter high school. We used shallow sentiment analysis to gauge the levels of various emotions experienced b...

We will prove two conditions for a tangential quadrilateral to be cyclic. According to one of these, a tangential quadrilateral is cyclic if and only if its Newton line is perpendicular to the Newton line of its contact quadrilateral.

The numerical integration of discontinuous functions is an abiding problem addressed by various authors. This subject gained even more attention in the context extended finite element method (XFEM), which exact crucial to obtaining reliable results. In this scope, equivalent polynomials represent effective circumvent while exploiting standard Gauss quadrature rule exactly integrate times step f...

In the present paper, a comparison between five different shell finite elements, including the Linear Triangular Element, Linear Quadrilateral Element, Linear Quadrilateral Element based on deformation modes, 8-node Quadrilateral Element, and 9-Node Quadrilateral Element was presented. The shape functions and the element equations related to each element were presented through a detailed mathem...

conclusions it was concluded that snake bite cases in kashan are similar to other areas in iran from an epidemiological point of view, including; age distribution rates, gender and site of the bites. the existence of macrov ipera lebetina, a dangerous venomous snake, can cause a range of clinical effects among residents in central parts of iran, such as kashan area. patients and methods this re...

background: snakebite is a serious public health problem in the world. the annual incidence of snakebites ranges from 4.5-9.1 in 100,000 population in iran. with regard to diversity of envenomation profiles in different geographical parts of iran, the aim of this study was to determine the demographical data, clinical and laboratory findings, and the outcome of the snakebite victims referred to...

Subelement patterns using bisection of edges and schemes for selecting edges to be split are described for the local refinement of elements in all-quadrilateral and quadrilateral-dominant planar meshes. Subelement patterns using trisection of edges are also described for the local refinement of elements in all-quadrilateral planar meshes. These patterns and schemes are easily extendible to quad...

Abstract A polygon P is called a reptile, if it can be decomposed into $$k\ge 2$$ k ≥ 2 nonoverlapping and congruent polygons similar to . We prove that cyclic quadrilateral then trapezoid. Comparing with results of Betke Osburg we find every convex rep...
