Serrated Microstrip Antennas are gaining their importance in the applications of dual and multiband antenna systems. A Serrated cutting edge has many small points of contact with the material being cut. The Serrations are mainly used in the Compact Antenna Test Range (CATR) measurements for the measurement of antenna parameters. In Serrations, by having less contact area than a smooth blade or ...

This report deals with the problem of determining independent contact regions on a 3D object boundary such that a seven finger frictionless grasp with a contact point in each region assures a force-closure grasp on the object, independently of the exact position of the contact points. These regions provide robustness in front of finger positioning errors in grasp and fixturing applications. The...

Over the past decade a growing number of high resolution, three-dimensional, X-ray computed tomography images of multiphase porous media systems have become available, as have the number of algorithms to analyze both the pore space and the fluid partitioning imaged within the voids. Here we consider the measurement of fluid-fluid and fluid-solid surfaces at residual fluid conditions in a Berea ...

This paper proposes a novel extractive summarization method for speech dialogues between agents and customers in contact centers. The proposed method does not require any extra cost for applying the method such as preparing rules or creating training data. Conventional methods such as the tf*idf method, which gives importance to characteristic words in an input text, can miss the essential poin...

[1] A technique for visualizing particle transport in the interior of a porous medium is presented. The technique, which includes the construction of a translucent medium and the use of laser-induced fluorescence for particle tracking, was used to examine the behavior of a dilute suspension of negatively charged, micron-sized particles in the interior of uniform glass bead packs during one-dime...

An algorithm which helps detecting in-line potato tubers without singulation when they are mixed with clods was developed. It is particularly useful for sorting and grading purposes whether at the packhouses or the potato harvester. The algorithm scans images which include clusters of tubers and clods from left to right until it encounters a cluster. Once encountered, a scan around the peripher...

Contact lenses are used as a method of correcting refractive errors. However, their use can be associated with periods of discomfort as well as occasional pathophysiological reactions. This inaugural edition of Optometry Rounds presents the latest findings to allow Optometrists to improve the experience of their patients who wear contact lenses, as well as to share knowledge with respect to con...

For the evaluation of pedestrian protection, the European Enhanced Vehicle-Safety Committee Working Group 17 report is now commonly used. In the evaluation of head injuries, the report takes into account only the hood area of the vehicle. But recent pedestrian accident data has shown the injury source for head injury changing to the windshield and A-pillar from the hood. The head contact points...

The Symmetry Set ( ) is the closure of the locus of centers of spheres tangent to smooth surface patches in two or more loci; such bitangent spheres are called “contact spheres.” The Medial Axis ( ) is the subset of the for which all such spheres are maximal, i.e., such that no other contact spheres are contained in them.2 A classification of points was introduced by Giblin and Kimia [6, 7], wh...

This prospective observational study analyzed conchal regrowth after laser-assisted turbinectomy (LATE) in brachycephalic dogs and the mucosal contact of regrown conchae. Eighty brachycephalic dogs (41 pugs, 39 French bulldogs [FBs]) that underwent LATE because of obstructing conchae were evaluated by endoscopy 7 days and 6 mo after surgery. At 6 mo, 96% of FBs' and 65% of pugs' nasal cavities ...
