Mesh Generation And CFD For A Drone’s Coaxial Rotor


Our Cadence Channel Partner in Scandinavia, neptech, shares a case study investigating the interaction of a coaxial rotor system and how to optimize its efficiency. Coaxial rotor systems are appealing for multirotor drones, as they increase thrust without increasing the vehicle’s footprint. However, the thrust of a coaxial rotor system is reduced compared to having the rotors in line. It... » read more

Electric Planes Taking Off


As the aeronautics industry and aviation startups design and test zero-emissions aircraft, they are solving problems beyond just adapting to fuel sources that cut greenhouse gas emissions. Problems of weight, noise, redundancy, refueling, cost, and turnaround time are being tackled one airline seat at time. Powerful tools can help aircraft designers look at the aircraft system as a whole, fe... » read more

Replicating da Vinci’s Aerial Vehicle Design


Unmanned aerial vehicles (UAVs), the prodigy of remotely piloted vehicles, largely used for military purposes, are slowly gaining momentum in our civil lives. Some of the applications of UAVs go beyond surveillance or photography: we already have drones that are employed by farmers to monitor crops and are used in the solar industry for thermographic studies. By 2026, UAVs for both consumer and... » read more

Development Of Distributed Intelligent Systems With The Robot Operating System


Networked robotic systems are increasingly prevalent. In addition to industrial robotics now firmly ensconced in manufacturing, applications are also being developed in the areas of logistics, medical technology, and even unmanned aerial vehicles (UAV) and unmanned underwater vehicles (UUV). In general, robotic systems are still centrally controlled by a PLC based on statically planned tasks... » read more

Power/Performance Bits: July 21


AI hardware Researchers at Purdue University, University of California San Diego, Argonne National Laboratory, University of Louisville, Brookhaven National Laboratory, and University of Iowa developed hardware that can learn skills, offloading some of the energy needed by AI software. "Software is taking on most of the challenges in AI. If you could incorporate intelligence into the circui... » read more

Covid-19 Tech Bits: April 14


Modeling coronavirus spread Four teams of Finnish researchers have modeled the coughing spread of COVID-19 in tight indoor areas, such as grocery stores and public transportation systems, using a supercomputer and 3D visualization. “The aerosol cloud spreads outside the immediate vicinity of the coughing person and dilutes in the process," said Aalto University Assistant Professor Ville V... » read more

AI Roadmap: A human-centric approach to AI in aviation


Source: EASA European Union Aviation Safety Agency February 2020 "EASA published its Artificial Intelligence Roadmap 1.0 which establishes the Agency’s initial vision on the safety and ethical dimensions of development of AI in the aviation domain. The AI Roadmap 1.0 is to be viewed as a starting point, intended to serve as a basis for discussion with the Agency’s stakeholders. It... » read more

Understanding SLAM (Simultaneous Localization And Mapping)


Amol Borkar, senior product manager for AI and computer vision at Cadence, talks with Semiconductor Engineering about mapping and tracking the movement of an object in a scene, how to identify key corners in a frame, how probabilities of accuracy fit into the picture, how noise can affect that, and how to improve the performance and reduce power in these systems. » read more

Week In Review: IoT, Automotive & Security


Internet of Things Qorvo, the company whose products sent pictures back from Pluto and Arrokoth (formerly Ultima Thule) on New Horizons, is showing off a couple smart home, IoT products at CES 2020 in Las Vegas next week. The company says its new transceiver chip QPG7015M will simplify gateway IoT design because the chip can simultaneously handle all open, smart home protocols, including ZigBe... » read more
