Where does Web 3 fit into, pertaining to industrial technologies ?

..One of the primary advantages is decentralized data storage and governance: Web3's distributed ledger technology (DLT) can be used to create secure and transparent platforms for storing and sharing industrial data. This can address concerns about data ownership, access control, and potential manipulation by centralized platforms. Web3 standards can create a common language for machines and data in industrial IoT, enabling seamless communication and data exchange between different devices and systems regardless of manufacturer or protocol. DLT can enable granular access control mechanisms, allowing different levels of access to specific assets for authorized users, increasing privacy and data protection..

When the wheels are coming off: Safety critical design and GSN- Goal Structured Notation

..Goal Structuring Notation (GSN) is a graphical argumentation notation used to visualize and structure arguments, particularly in safety-critical systems. It provides a clear and concise way to show how evidence supports claims, and how those claims contribute to overall safety goals. GSN diagrams facilitate collaboration and review. They can be shared and discussed among stakeholders to ensure consensus on safety arguments. While GNS system is greatly useful in designing an eVTOL aircraft, the merits go beyond aerospace or medial applications. At Azle we deploy GSN themes even for smaller electronics. It is part of our ASEE process..

How to organize world's airspace to accommodate commercial and unmanned aviation

.. Pertaining to technology, we are always in search of silver bullets. And they don't exist ! We have not yet completely defined what are the requirements for accommodating both commercial and general aviation along with advanced aerial mobility, commercial drones and recreational drones in the same operable airspace. Early solutions in this saga tried to compartmentalize the problem into data streams, information architecture, apps away from actual connectivity. However the later efforts to define connectivity went after more silver bullets, even without shying away 5G or the other tech named after a medieval king of Denmark and Norway..

What are the "Jitters" inside a computer? Examining computation architecture for safety critical applications

.. For the same processor under the same conditions, there are many other factors impacting the time of execution of the same sequence of instructions ! This can be much more pronounced if branching instructions are involved. Even without factoring a user program or an OS/RTOS scheduler, there are numerous CPU-level nuances that lead to variations and unpredictability in execution time. Electrical jitter is normally understandable in a bus system that could potentially cause communication errors. But jitter is inherent in all electronic circuits, including the digital circuits which are building blocks of any microprocessor..

Sacrificing high quality audio; at the altar of digital distribution efficiency

.. Blame psychoacoustics and the early compression algorithms that divided and "conquered" the audio in frequency domain and also in the time domain. We also forget the early struggles of a clean linear amplifier design. Most of the portable audio players depended on the so called Class-D amplifiers, those caused observable distortion. Before we characterize the distortion, we need to understand the nature of each element in the signal chain in the player at the consumption end of music. And ideal system would mimic the consumption happening live at the production end of the music..

The interdependent triad of drone delivery con-ops: Safety, Reliability and Scalability

.. It is generally ideal to view the con-ops separate from the aircraft itself. Even though the three elements of safety, reliability and scalability stem from the same attributes of the aircraft itself, this is not a sufficient condition to assure operational outcomes. The operational outcomes heavily depend on not just well defined policies and procedures, but the electronics and software systems supporting the policies and procedures. But the first domino that should never fall in the scheme is the continuous process of keeping up with the aircraft ..

AAM, Advanced Aerial Mobility: Do the so called vertiports make any sense ?

.. As it has been repeatedly established that vertical landing maneuver takes up more energy and power than vertical takeoff itself. Plus the operational definition of what constitutes a safe  vertiport operation has not been standardized, including a mention of the kind of equipage necessary such as omnidirectional range finding. It necessitates a great degree of accuracy and precision in vertical and lateral guidance to both pilot and autopilot..

Structural battery in electric aviation and causes of concern

.. There has been nothing controversial about holding highly combustible fuel in the wings of an airplane, even though the wing itself is the most critical structural part of the whole system. In additional there is fuel management subsystem with sensors and pumps automatically detecting fuel levels and balancing them out. For a highly combustible battery based system it is an entirely different argument..

Is there really a business case for startup conglomerate?

.. Modern problems stem from complex interdependency of many different technologies playing together..
