In this paper, a class of all-metal cavity-backed slot array employing multiple layers, corporate-feed waveguide network, and coaxial-to-ridged waveguide transition is proposed.The frequency band flexibility of this class of array with a fixed aperture is demonstrated using the direct metal laser Medical and Ambulatory supplies / Wound Care sinteri
ObjectiveAmbulance-based secondary telephone triage systems have been established in ambulance services to divert low-acuity cases away from emergency ambulance dispatch.However, some low-acuity cases still receive an emergency ambulance dispatch following secondary triage.To date, no evidence exists identifying whether these cases required an emer
Mobile mapping systems are increasingly being used for the acquisition of 3D information of the environment.Although these systems are very efficient in data capturing compared to more traditional methods, the high cost of high-end accurate Accessories mobile mapping systems is a major drawback.In contrast, the much cheaper low-end mobile mapping s
To explore the contamination of heavy metals in the Shi River Basin soil in China, a high density sampling of surface soil was conducted.In this study, an Accessories absolute principal component scores multiple linear regression model (APCS-MLR) was used to identify the sources of heavy metals in the soil and quantify their amounts.The methods to
