Non-invasive tools play a crucial role in the diagnosis, evaluation, and management of virtually all patients suspected to have or who have had cardiac arrhythmias. These non-invasive tools can help determine the clinical significance and prognostic importance of the arrhythmia and can help assess risk of serious arrhythmic consequences including death. Based on a non-invasive assessment, the need...
In this paper, a compact omnidirectional circularly polarized (CP) cylindrical dielectric resonator antenna (DRA) is presented. The DRA is excited in its TM01δ mode by a probe located at the center, giving linearly polarized (LP) omnidirectional radiation patterns. Four interleaved strips serving as a wave polarizer are placed on the top of the DRA. By tuning the strips, the LP fields can be changed...
Based on granular space, the hierarchical structure invariance and optimal approximation for proximity data are presented, and four results are obtained as follows. Firstly, an improved algorithm for computing the hierarchical structure and the related min-transitive closure of a fuzzy proximity relation are given, and the properties of key point sequence are studied by introducing the key points...
The compact wideband circularly polarized (CP) hollow dielectric resonator antenna (DRA) with an embedded vertical feed network is investigated. A printed quadrature hybrid coupler is used as the feed network. Since the footprint of the feed network is small, the design can be very compact. For demonstration, a hollow cylindrical CP DRA was designed at ∼2.4 GHz for WLAN applications. The reflection...
Multi-source heterogeneous information fusion is an extremely challenging problem because of the complex and highly irregular nature of environment. We consider decision fusion problem in the presence of m-dependent evidences in this paper. A new evidence fusion approach for decision of proactive service has introduced, which is extending of Class D-S Evidence method. We applied this approach in our...
In this study, compared with other dataset, Tropical Rainfall Measurement Mission (TRMM) helps more to investigate the relationship between post-landfall tropical cyclones (TCs) precipitation and narrow mountain effect, during pre-monsoon period in Irrawaddy Delta (ID) region. It shows that if TC rounds the mountains located north of ID region, rainfall will mainly spread over ID district. By contrast,...
