The aim of this archive is to show examples of raw LoRa and LoRaWAN stack implementation using the ISP4520 module. The ISP4520 offers a unique combination of two leading IoT radio technologies in one ...

Abstract: A broadband beamformer is proposed based on nested hexagonal arrays, hexagonal frustum filters and multirate techniques. The nested hexagonal arrays used here consist of several hexagonal ...

Multiple data sources confirm a sharp decline in Stack Overflow’s usage and content activity over the past few years. By late 2024, Stack Overflow’s core Q&A activity had receded to levels not seen ...

Today, the United States leads the world in generative AI. Its frontier labs set the pace in model development, U.S. firms control more than half of the world’s AI accelerators, and U.S. capital ...

The network will activate the awaited upgrade on 28 August. The Nakamoto update looks to transform DeFi on the Bitcoin blockchain. These developments could extend STX’s resurgence. Stacks (STX), one ...

Abstract: The terminal antenna with dual-circular polarization reported here operates around 20 and 30 GHz, that is, in the down- and uplink frequency bands of current satellite communication systems.

This post summarizes my research into placing the semantic layer within the modern data stack. I'll be presenting my research at the Semantic Layer Summit on April 26, 2023. The white paper version of ...

Recent years have seen the rapid growth of new approaches to optical imaging, with an emphasis on extracting three-dimensional (3D) information from what is normally a two-dimensional (2D) image ...

We propose a method called Node Replication (NR) to implement any concurrent data structure. The method takes a single-threaded implementation of a data structure and automatically transforms it into ...

The CS5340 performs sampling, A/D conversion and anti-alias filtering, generating 24-bit values for both left and right inputs in serial form at sample rates up to 200 kHz per channel. We used FT2232H ...
