Abstract: This paper proposes a high-density array antenna utilizing narrow antenna elements to achieve high-power rectenna DC arrays. A microstrip antenna employing a narrow antenna element has a ...

Scientists have discovered a new way of creating superheavy elements by firing supercharged ion beams at dense atoms. The team believes this method could potentially help synthesize the hypothetical ...

Currently, XGBoost has a GHistIndexMatrix which stores data in CSR format; however, if the data is completely dense (no missing data such as NaNs), it optimizes this away by not reserving the extra ...

The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Two integer arrays of length L1 and L2 are passed as input. The program must print the sum of the distinct elements present in both the arrays. That is the program must print the count of integer ...

Abstract: In the present paper, the analysis of phased antenna arrays made in microstrip technology that can be arranged on an aircraft/UAV is proposed. The antenna arrays will have as a radiating ...

A new radial-line helical array (RLHA) using dual-branch helical antennas has been designed for improving the power capacity of RLHAs. The helical element is cavity-backed to lower the mutual coupling ...
