In this paper, we study the weak point matching problem for a given set of n points and a class of equilateral triangles. The problem is to find the maximum cardinality matching of the points using equilateral triangles such that each triangle contains exactly two points and each point lies at most in one triangle. Under the non-degeneracy assumption, we(More)
Mobile users often connect through WiFi access points and frequently find themselves behind NATs that are built into common off-the-shelf home access points or enterprise wireless deployments. Punching a hole through the NATs to establish a P2P connection can be a challenging task for lay users. We present our system, ANT, that utilizes Audio signaling for(More)
The shape and center of mass of a part are crucial parameters to algorithms for planning automated manufacturing tasks. As industrial parts are generally manufactured to tolerances, the shape is subject to variations, which, in turn, also cause variations in the location of the center of mass. Planning algorithms should take into account both types of(More)
We study the problem of orienting a part with given admitted shape variations by means of pushing with a single frictionless jaw. We use a very general model for shape variations that is defined by two given convex polygons <formula formulatype="inline"><tex Notation="TeX">$P_I \subseteq P_E$</tex></formula>. In this model, any valid instance must contain(More)
Metrology, the theoretical and practical study of measurement, has applications in automated manufacturing, inspection, robotics, surveying, and healthcare. An important problem within metrology is how to interactively use a measuring device, or probe, to determine some geometric property of an unknown object; this problem is known as geometric probing. In(More)
Let A = {a1, a2, ..., as}, and B = {b1, b2, ..., br} be two sets of points such that s + r = n. Also let CA = {α1, α2, ..., αs} and CB = {β1, β2, ..., βr} be the capacities of points in A and B. We define minimum limited capacity matching and call it MLC-matching that matches each point ai ∈ A to at least one and at most αi points in B and matches each bj ∈(More)
OBJECTIVE The aim of this study was to investigate the comparison of massage therapy and routine physical therapy on patients with sub acute and chronic nonspecific low back pain. METHODS AND MATERIALS Thirty volunteer female subjects with a sub acute or chronic nonspecific low back pain were randomly enrolled in two groups, massage therapy and routine(More)
