This paper proposes a ray-model-based straight-line extraction method for the grid map of mobile robot, call RM-Line. First, edge is obtained, with help connectivity blank grid. Then, points containing complete line information, called active points, are obtained using screening model. Lastly, ray model designed to segments. We evaluate algorithm number lines, average distance from grids and ru...

This article describes the main provisions of rapid law concept idea introducing blank norms into legislation, content which is possible by accessing special databases designed to consider threats posed free circulation cryptocurrency assets greatest extent.
 These conclusions are based on analysis dangers using cryptocurrencies broad segments population, lack effective mechanisms for cont...

We have designed and fabricated a standardized specimen holder that allows the operation of a microelectromechanical system (MEMS) device inside a transmission electron microscope (TEM). The details of the design and fabrication processes of the holder are presented. The sample loading mechanism is simple and allows reliable electrical contact to eight signal lines on the device. Using a MEMS-b...

Contactless atmospheric pressure ionization (C-API) method has been recently developed for mass spectrometric analysis. A tapered capillary is used as both the sampling tube and spray emitter in C-API. No electric contact is required on the capillary tip during C-API mass spectrometric analysis. The simple design of the ionization method enables the automation of the C-API sampling system. In t...

This paper presents the design and electromagnetic characterization of a 3D-printed 2-way broadband power divider intended to work in RF band from several hundred MHz up few GHz. The is based on use helical-microstrip transmission line segments. Two different topologies tapered segments are considered prior deciding final divider. characteristic impedance profiles both analyzed by means simulat...

Although vibration monitoring is a popular method to monitor and assess dynamic structures, quantification of linearity or nonlinearity of the dynamic responses remains a challenging problem. We investigate the delay vector variance (DVV) method in this regard in a comprehensive manner to establish the degree to which a change in signal nonlinearity can be related to system nonlinearity and how...
