Over at Worldbuilding SE, I wondered whether focusing the maximum output of a cell phone tower on a specific target could deliver enough power to cause harm, probably by heating a victim's tissue; ...

The value of resistance is 3Ω and inductor impedance is j4Ω. As far as I have learned the wattmeter measures instantaneous power but shows reading for average power. As I solved for the given values the power comes out 12W in both cases even though they are connected at different points in the circuit and I want to know why? I can't seem to figure out the reason behind this. Can someone please po…

Tokyo-based startup MW is offering homes with built-in robotic housekeeping arms, a counter to a global embrace of humanoids. MW aims to sell its first robot-equipped home in Tokyo by 2028 and build as many as 10,000 units a year by 2035, the equivalent of 5% of new homes now being built in Japan, according […]

Researchers at the NIST, UCSD et al. published a technical paper titled “Predicting Cure Evolution and Thermal Endurance of a Highly Filled Epoxy Underfill for Advanced Packaging.” Abstract Excerpt: “Epoxy underfill materials are critical to advanced semiconductor packaging by enhancing mechanical integrity, redistributing thermomechanical stresses, and improving solder-joint reliability in flip-…

At the headquarters of RENOLIT SE (Worms, Germany), construction work on a new plant for mixing formulations as part of raw materials processing — known as the “mixing plant” — is progressing. Earthworks for the project began in February this year, and the precast concrete elements are currently being installed. With a planned investment of […] The post Renolit invests €56 million in automated mi…

Samsung E&A Co., Ltd. (Seoul, South Korea) signed an Engineering, Procurement and Construction (EPC) contract with Saudi Arabia’s SABIC Agri-Nutrients Co. (Jubail, Saudi Arabia) for the SAN-7 Project. The contract is worth KRW 4.7 trillion (about USD 3.5 billion), and Samsung E&A will exclusively carry out the EPC, with completion scheduled for 2030. The signing […] The post Samsung E&A wins EPC …

Constellation’s Limerick plant has generated nuclear power in the community of Pottstown, Pa., northwest of Philadelphia, since the first of two boiling water reactors came on line 40 years ago, in 1986. The plan is to keep Limerick running for at least another 40 years, but from a control room that would look wholly unfamiliar to its 1980s-era operators. Limerick is set to get a major safety-rel…

It is 3:00 AM, database connections are dropping, and the on-call engineer is staring at a diagram routing traffic through a cluster decommissioned six months ago. The diagram looked immaculate in Notion, passed review without objection, and actively lied about production topology. Drawing boxes is cheap. Deciding whether an architecture diagram accurately reflects runtime reality after three spr…

The following problem is from a book. The filter and load of a de/de converter are as shown in Fig. 2.16. The input de voltage source is 100 V, and the required dc load voltage (the average value of ...

Most microbial life on Earth exists as biofilms, large interkingdom microbial communities living within a self-synthesised matrix of extracellular polymeric substances. These living structures are critical to the survival of all life on Earth, driving biogeochemical processes within ecosystems and performing key functions in the maintenance of animal and plant health. As powerhouses of these life…

UMBC mathematician Matthew Kvalheim has received an Air Force Office of Scientific Research Young Investigator Program Award to develop better ways of simplifying hybrid systems, like a drone swarm, humanoid robot, or aircraft. Kvalheim aims to create mathematical tools that make hybrid dynamics—which govern almost all real-world systems—easier to study and control, giving researchers a clearer “…
