The design of a novel volcano smoke antenna for UWB indoor applications is presented. The design method is based on a general description for the geometry of UWB monopole antennas which is capable of producing most possible shapes for these antennas. It is also compatible with different optimization methods. In addition to a volcano smoke antenna, this method is used to design two optimized mon...
Funding Information Natural Science Foundation of China, Grant/Award Number: 61532002 and 61672237 ; National High-tech R&D Program of China (863 Program), Grant/Award Number: 2015AA016404 ; Doctoral Program of Higher Education, Grant/Award Number: 20130076110008 Abstract Many complex natural phenomena with dramatic spatial and temporal variation are difficult to animate accurately with anticip...
A technique based on an adaptive filter using the least-mean-square algorithm is proposed for detection of multipath change in permanent, continuously operating GPS (CGPS) stations. The technique has been tested on some experimental data, indicating that the multipath change above the receiver noise level can be detected. Further tests have been conducted with some CGPS data from the Japanese G...
Cannabis sativa L. (cannabis) extracts, vapor produced by the Volcano vaporizer and smoke made from burning cannabis joints were analyzed by GC-flame ionization detecter (FID), GC-MS and HPLC. Three different medicinal cannabis varieties were investigated Bedrocan, Bedrobinol and Bediol. Cannabinoids plus other components such as terpenoids and pyrolytic by-products were identified and quantifi...
Cannabis sativa is a well-known recreational drug and, as such, a controlled substance of which possession and use are illegal in most countries of the world. Due to the legal constraints on the possession and use of C. sativa, relatively little research on the medicinal qualities of this plant has been conducted. Interest in the medicinal uses of this plant has, however, increased in the last ...
in this paper a new low profile substrate integrated waveguide (siw) probe-fed h-plane horn antenna structure with improved gain is proposed. the proposed antenna consists of two waveguides including a rectangular and a taper one, in which both, first and third modes of the structure are simultaneously excited leading to a uniform field distribution along the radiating aperture of the antenna a...
What is currently needed for optimal use of medicinal cannabinoids is a feasible, nonsmoked, rapid-onset delivery system. Cannabis "vaporization" is a technique aimed at suppressing irritating respiratory toxins by heating cannabis to a temperature where active cannabinoid vapors form, but below the point of combustion where smoke and associated toxins are produced. The goal of this study was t...
Cannabis vaporization is a technology designed to deliver inhaled cannabinoids while avoiding the respiratory hazards of smoking by heating cannabis to a temperature where therapeutically active cannabinoid vapors are produced, but below the point of combustion where noxious pyrolytic byproducts are formed. This study was designed to evaluate the efficacy of an herbal vaporizer known as the Vol...
