The wear mechanism of plasma electrolytic nitrocarburised (PEN/C) 316L stainless steel samples was studied after a pin on disc wear test. The surface morphology of samples after application of PEN/C process was studied using scanning electron microscope technique. The sliding tracks resulting from the wear tests on the treated specimens indicated no signs of plastic deformation and adhesive wea...

BACKGROUND Suspected penicillin allergy (Pen-A) is often not verified by diagnostic testing. In third line penicillin allergy labels were associated with prescription of broad spectrum antibiotics, hospital stay duration and readmission. OBJECTIVE Assess the impact of Pen-A labels on antibiotic and health care use in primary care. METHODS A retrospective cohort study was conducted in primar...

Delimiting communities in marine habitats is diYcult because co-occurring species often have diVerent life histories and the life stages experience the environment at diVerent spatial scales. The habitat of a particular community is embedded within a larger habitat or ecosystem with many species shared between the focal community and the larger system. Pen shells (Atrina rigida) are large bival...

In the present study, the effect of intrauterine infusion of Zataria multiflora extract on the clinical endometritis was investigated. Vaginal examination, transrectal palpation and ultrasonography were used to inspect the genital tract at 30-40 days in milk and two weeks later the same approach was applied. Cows with clinical endometritis were randomly divided into three treatment gro...

A proper segmentation of pen marking enhances shape recognition and enables a natural interface for sketch-based modeling from simple line drawing tools to 3D solid modeling applications; user input is otherwise restricted to draw only one segment per one stroke. In general, the pen marking segmentation is achieved by detecting the points of high curvature-called, segmenting points-and splittin...

Sketch interactions based on interpreting multiple pen markings into a 3D shape is easy to design but not to use. First of all, it is difficult for the user to memorize a complete set of pen markings for a certain 3D shape. Secondly, the system will be waiting for the user to complete the sequence of the pen markings, often causing a certain mode error. To address these problems, we present a n...

This paper describes the Magic Pen, a modified pen that allows natural cable-less interaction with AR environments. The pen is a normal pen with bright Light Emitting Diodes (LEDs) mounted at each end. Using computer vision techniques, these LEDs are tracked in the image captured by a head-mounted camera, and the pen’s position and orientation are computed. This permits the use of image plane i...

Conceptual design is usually done with paper and pen. Notepad computers open a new way for designing pen-based user interfaces for supporting such kind of design activities. However, pen-based user interfaces have some aws, such as the recognition rate of handwritten characters, the size of memory and display, which limits the application of such kind of computers. The main idea we have is to c...

A prospective, double blind study was conducted to determine the degree of concordance of pen and palpation methods of measuring skin induration to Mantoux tuberculin tests. One hundred thirty-five skin tests were performed in patients with previously bacteriologically proved tuberculous disease. An experienced reader who was only able to see the forearm of the patient measured the induration b...

This paper describes the Tezpur University dataset of online handwritten Assamese characters. The online data acquisition process involves the capturing of data as the text is written on a digitizer with an electronic pen. A sensor picks up the pen-tip movements, as well as pen-up/pen-down switching. The dataset contains 8,235 isolated online handwritten Assamese characters. Preliminary results...
