I tried to simulate a circuit from MIT Power Electronics Lecture 2, and this is the simulation when it has reached periodic steady state. I added ground, original circuit didn't have one. Yellow line - v(vy, vz) - should be voltage across inductor L2. I know that the negative... Read more

I want to build something that include fans. Long story short, I am thinking of buying 8 computer case fans, 3d print a housing and install the case fans to create a specific airflow corridor. The DIY ...

Discover the latest enhancements in Simcenter Flux 2026.1, including accelerated electromagnetic simulations, improved modeling productivity, expanded engineering workflow connectivity and emerging approaches leveraging surrogate models and optimization.

For asset managers and equipment engineers, mastering Dissolved Gas Analysis (DGA) interpretation is essential, because gases like carbon monoxide and carbon dioxide are the first chemical signals that a transformer's solid cellulose insulation is overheating and degrading. Your transformer can talk, and if you know how to listen, you will hear it. Inside every oil‑filled power transformer, a sil…

Simcenter Fluxmotor 2026.1 introduces new capabilities for multiphase machine design, thermal-aware performance evaluation and enhanced connectivity across the Simcenter portfolio, helping engineers accelerate machine development from concept exploration to connected engineering workflows.

How do insulated-gate bipolar transistors (IGBT) (IGBTs) handle high currents despite the PNP region in its equivalent circuit being driven in active mode? My understanding is that active mode bipolar ...

I Built a 4-Sided Plot Area Calculator with 2D & 3D Visualization Most online plot calculators only work for simple rectangular plots. However, many real-world properties have four sides with different measurements, making area estimation much more difficult. That's why I built a 4-Sided Plot Area Calculator that allows users to enter the North, South, East, and West dimensions and instantly calc…

With the continuously increasing demand for AI and cloud computing services, data centers are growing...

I know nothing about engineering. I just wanted to satisfy my curiosity. Here is a picture (an ASCII picture of a factory with a wedge-top roof and some smoke from the chimney). > ...

I have a 3 phase star transformer circuit which is modeled in LTspice as below: I am using a 120V RMS, 60 Hz supply in each of three phases. Its peak value is 169.67V in each phase with a 120° phase ...

Traditional databases just can't keep up with high concurrency and low latency at the same time. The term "real-time" has become kind of meaningless. Everyone claims it, from batch-oriented cloud data warehouses to transactional database extensions. This makes picking the right architecture really hard without expensive trial and error. The best real-time analytics database in 2026 depends entire…

Cloudy underwater conditions can be a major problem for robotic vehicles exploring the ocean. When underwater robots land on the seafloor, inspect shipwrecks, or dig into sandy areas, they often stir up clouds of sediment that block their cameras. In many cases, operators have no choice but to wait for the water to clear before […] The post New sonar-camera system could help underwater robots nav…

Code review is a critical software engineering practice for improving software quality, enforcing coding standards and supporting knowledge sharing. Incorrect code reviews that deviate from established standards can provoke negative affect and perceptions of unfairness among code contributors, thereby impacting their code revision performance. Advancement in large language models have enabled aut…

Software development is undergoing a paradigm shift driven by Generative AI (GenAI), promised to revolutionize developer productivity. However, this rapid transformation risks exacerbating the long-standing challenge of technical debt. While current literature speculates on these risks, there is a critical absence of empirical, longitudinal evidence quantifying how widespread GenAI adoption is al…

Low-code and no-code (LC/NC) platforms enable nontechnical professionals to build software, forcing organizations to balance autonomy with oversight so initiatives align with strategic goals. This multi-case study examines how governance mechanisms in LC/NC environments shape psychological ownership and autonomy, and how these dynamics affect development outcomes. We introduce perceived controlla…

Ask someone to name the most important chip ever made and they will reach for a processor: an Intel CPU, an ARM core, maybe the microcontroller inside an Arduino. The real answer is humbler and far more widely produced. The best-selling integrated circuit in history is the 555 timer - an eight-pin part designed more than fifty years ago that is still manufactured by the billion every single year.…

The Sydney Harbour Bridge Cycleway Ramp redefines access to one of Australia's most significant pieces of public infrastructure. For decades, the northern approach to the Bridge's cycleway ended in stairs, breaking one of the city's most iconic journeys. This project replaces that stair-only access with a safe, legible and fully accessible ramp, completing a long-missing link in Sydney's cycling …
