Green Hills Software, Inc. unveiled a minuscule embedded operating system with a ROM footprint as small as 1,600 bytes. Called µ-velOSity, the new RTOS offers a RAM footprint, as small as 1,600 bytes and service call times as low as 30 cycles. Green Hills' engineers say the new OS supports ARM technology, PowerPC host processors, as well as select Freescale ColdFire embedded controllers. They foresee its use in MP3 players, disk controllers and wireless control applications. Read more about it at http://rbi.ims.ca/ 4924-578.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
