In this paper, a 2 DOF haptic yawing joystick for use as the navigation input device in virtual environments is introduced. The haptic yawing joystick can perform a 360°_range yawing motion and ±100°_range pitching motion. The device can support weights of up to 26N along the x axis and 10N along the y axis with 10kHz of sampling rate. For the haptic yawing joystick, an ellipse navigation algor...

InGaAs p-i-n photodiodes will be used in the CMS tracker to receive the digital timing and control signals transmitted from the Front End Controller (FEC) boards by 1310nm wavelength lasers. These devices should be sufficiently rad-hard to survive the fluences/doses encountered in the tracker during a ten year operational period. Candidate p-i-n diodes have been irradiated, in a fully packaged,...

Multilevel inverter as compared to single level inverters have advantages like minimum harmonic distortion, reduced Electro Magnetic Interference (EMI/RFI) generation and can operate on several voltage levels. In this paper a new topology of cascaded multilevel inverter using reduced number of switches, resulting in higher output voltage levels is proposed. There are five series connected H-bri...

The point placement problem is to determine the positions of a linear set of points, P = {p1, p2, p3, . . . , pn}, uniquely, up to translation and reflection, from the fewest possible distance queries between pairs of points. Each distance query corresponds to an edge in a graph, called point placement graph (ppg), whose vertex set is P . The uniqueness requirement of the placement translates t...

Abstract— Ironically, despite the growing familiarity with composite materials and ever-increasing range of applications, use of natural fibers as reinforcement in polymeric composites for technical application has been a research subject of scientist. Pineapple leaf fibre (PALF) is one of them that have also good potential as reinforcement in polymer composite. In this present work, an experim...

Let P be a set of n points on the plane in general position. We say that a set Γ of convex polygons with vertices in P is a convex decomposition of P if: Union of all elements in Γ is the convex hull of P, every element in Γ is empty, and for any two different elements of Γ their interiors are disjoint. A minimal convex decomposition of P is a convex decomposition Γ′ such that for any two adjac...

Abstract Second and third generation single crystal (SX) Ni-based superalloys are considered to be sensitive microsegregation, incipient melting microstructural instability. Thus, their thermodynamic properties stability at high temperatures of key importance. Vapour composition consisting four species has been detected in the temperature range 1453–1573 K. This was found after studies three CM...

BACKGROUND Research on medical vocabulary expansion from large corpora has primarily been conducted using text written in English or similar languages, due to a limited availability of large biomedical corpora in most languages. Medical vocabularies are, however, essential also for text mining from corpora written in other languages than English and belonging to a variety of medical genres. The...
