On 12th August 2022, the U.S. Department of Bureau of Industry and Security (BIS) announced that it would cut off the supply of Electronic Computer-Aided Design (ECAD) software specially designed for the development of integrated circuits with Gate-All Around Field-Effect Transistor (GAAFET), two substrates of ultra-wide bandgap semiconductor (Gallium Oxide, Ga2O3), and diamonds, and Pressure Gain Combustion (PGC) technology.

How is your personal privacy information leaked? — Information leakage is hard to avoid. Personally, in addition to installing the national anti-fraud center app and being cautious when you transfer money. If you are an iPhone user, be sure to click “Ask App Not to Track”.

Blockchain is a combination of data blocks in a time-sequential manner and cryptographically guarantees that they cannot be tampered with and are unforgeable. The data is jointly recorded by all nodes of the system, and all nodes do not need to belong to the same organization, nor do they need to trust each other. Also, the data is jointly stored by all nodes, and each participating node can copy and obtain a complete record copy.

Blockchain technology solves the problem of trust between people and institutions so that the data communication and network communication of the Internet become real. — Blockchain technology is an important technological innovation in the field of financial technology (Fintech). As the core technology of the Distributed Ledger Technology (DLT) platform, blockchain is considered to have broad application prospects in many fields such as finance, credit reporting, Internet of Things, trade settlement, and asset management. The…

Blockchain is a shared, immutable ledger that facilitates the process of recording transactions and tracking assets in a business network. — Introduction Blockchain technology is still developing rapidly, and the relevant standards are still being normalized. A blockchain is a digital ledger that is kept by multiple interconnected computers and distributed among them. A blockchain consists of consecutive “blocks” that hold records of relevant information (amount, various recipient addresses, transaction time, location…

Interaction Overview Diagram = Activity Diagram + Sequence Diagram — The interaction overview diagram focuses on an overview of interaction control flow. It is a variant of an activity diagram where nodes represent interaction. It is very similar to the activity diagram with many nodes (start, end, judge, merge, fork, and join). Also, it introduces 2 new elements (interaction occurrence…

Timing diagrams are another form of interaction diagram. It focuses on timing constraints across different objects or actors, not just the relative order of messages. — Timing diagrams focus on the change in state or value of one or more objects along a linear time axis. It can show the interaction between events and the time and duration constraints that govern them. The concept Lifeline It represents the life cycle of an object in the interaction.

Systems engineering is an emerging discipline, which takes complex systems as the research object, and designs develop, manages, integrates, and controls complex systems over their life cycles according to certain purposes, in order to achieve the best overall effect, theory, and method. — SysML Diagram — Model-Based System Engineer (MBSE) — Overview (1) The Systems Modeling Language (SysML) is a general-purpose modeling language for systems engineering applications.
