This paper investigates the performance of using multiple intelligent reflecting Ice Maker surface (IRS)-assisted communication as compared to the hybrid approach.We demonstrate that for practical scenarios with a limited amount of radiated power, the performance can be significantly enhanced by increasing numbers of IRS.Upper bounds are derived fo
Background: To compare 24-hours versus 48-hours nasal packing in terms of discomfort and effectiveness in preventing septal haematoma and bleeding after sub-mucosal resection of nasal septum.Methods: In this randomized controlled trial PHONE CASE 160 patients of symptomatic deviated nasal septum (DNS) were included.The sample was randomly divided i
Based on the historical fault data of pantograph of CRH380BL EMUs, the fault distribution law of four main fault parts was studied by using the method of reliability data analysis, and then the reliability level of pantograph system was evaluated.ADD and air supply pipe, air supply pipe line, 10-X01 relay and pantograph airbag were the four parts t
The behavior of braced steel frame structures is of special importance due to its extensive use.Also the application of active and semi-active control systems, regarding to their benefits in obtaining better seismic performance Ice Maker has increased significantly.The majority of the works on steel structures and steel connections has been done un
