Reconfigurable intelligent surfaces (RISs) have the potential of realizing emerging concept smart radio environments by leveraging unique properties metamaterials and large arrays inexpensive antennas. In this article, we discuss applications RISs in wireless networks that operate at high-frequency bands, e.g., millimeter wave (30-100 GHz) sub-millimeter (greater than 100 frequencies. When used networks, may a manner similar to relays. The present paper, therefore, elaborates on key...

One consideration during the design of long range controlled electrical system is sudden outage a Personal Computer (PC) caused by power failure. Frequent can damage components inside PC such that whole could be malfunction. This affect cost, time, and effort required to fix system. Usually equipped with temporary storage or UPS (uninterruptible supply) small capacity, so in immediately turned off before runs out. Therefore it necessary control shutdown automatically within certain time...

The outage probability of maximal-ratio combining (MRC) for a multiple-input multiple-output (MIMO) wireless communications system under Rician fading is given by the cumulative distribution function (CDF) largest eigenvalue complex noncentral Wishart matrix.

In the last decade, Bandung has become one of tourism destination places in Indonesia. It is reported that almost 6.7 million visitors come to 2018, and number increased by 4% per year since 2014. This rise leads establishment several toll gates as main access points throughout city. As busiest ones, Buah Batu gate frequently congested because location close southern part Bandung. To overcome this problem, a traffic regulation based on computer simulation urgently required. study, we...
