This research studies the performance of a battery-free wireless antenna sensor for measuring crack propagation. In our previous work, a battery-free folded patch antenna was designed for wireless strain and crack sensing. When experiencing deformation, the antenna shape changes, causing shift in electromagnetic resonance frequency of the antenna. The wireless interrogation system utilizes the ...
Generally microstrip patch antenna (MPA) is used in modern communication devices and day-to-day communication is done through it. Study of literature of past few year shows that, the leading work on MPA is design compact size broadband microstrip antenna, but inherently MPA have narrow bandwidth so various techniques are engaged to enhance bandwidth. This review paper demonstrates some commonly...
Recent studies suggest that manipulation of landscape patterns is the most preferred method to reduce susceptibility of landscape to fire spread. e evaluated the effects of landscape spatial pattern and spatial heterogeneity of fuel loading on surface fire spread using the FARSITE model n Chequamegon National Forest landscape, Wisconsin. Five forest management scenarios were developed to genera...
Here we report a novel approach for preparation of a 6-day transdermal drug delivery system (TDDS) as treatment for mild to moderate Alzheimer's disease. The spray drying method was used to prepare microparticles containing the anti-Alzheimer drug, Rivastigmine, in combination with the natural polymer, chitosan, for transdermal drug delivery applications. The content of the drug was determined ...
This paper presents the electrically small U-slot loaded circular microstrip patch antenna with Complementary Split Ring Resonator (CSRR). The technique of U slot loading is used for operating antenna in dual band and CSRR technique to make antenna compact and CSRR for compactness is used. The simple circular patch antenna resonates at 5. 71 GHz with return loss of -11. 38 dB. The proposed ante...
