performance. Let us consider the case of a single-threaded system. According to Moore’s law‚ transistor dimensions are scaled by 30% (0.7x) every technology generation‚ thus reducing their area by 50%. This reduces the delay (0.7x) and therefore increases operating frequency by about 40% (1.4x). Finally‚ to keep electric field constant‚ voltage is reduced by 30%‚ reducing energy by 65% and power (at 1.4x frequency) by 50%‚ since active power = CV2f. Therefore‚ in every technology generation transistor density

is Linux? Which parts of the Linux operating system did each provide? Who else has helped build and refine this operating system? GNU stands for "GNU’S Not Unix"‚ and it was designed to be a UNIX-like operating system developed by Richard Stallman. Linux is the name of operating system kernel developed by Linus Torvalds. GNU’s tools aside the Linux kernel make the operating system known as “Linux” aka “GNU/Linux”. Thousands of people helped refine the operating system online. Chapter 2 1. Briefly

Operating rooms are creating a disproportionate amount of waste for the space they occupy in a hospital‚ accounting for 20-30% of all hospital waste (Kagoma et al. 1905 ). Imagine a bustling operating room: a patient is being operated on and there are surgical instruments laid out on a blue tarp-covered table. The surgeon asks a nurse for gauze and the ripping open of the package is heard‚ which is then thrown in the trash. Supply after supply is unveiled in their sterilized package‚ and one by one
