challenge for computer engineers from the start was deciding how to transfer data through the computer. The first computer, the ENIAC, required 18,000 vacuum tubes to do so, and weighed about 20 tons. Because of its huge size, its power consumption was 150,000 watts (Piguet). Evidently, size and power consumption were major issues from the start. Vacuum tubes were a continuous source of difficulty due to expenses, and the fact that they were constantly burning out. Eventually, the invention of…

Some of them are briefly discussed below: • Low cost: The fabrication procedures involved in the Vacuum assisted resin infusion process use relatively low cost equipment for the quality of composite manufactured. • High performance light weight laminates manufactured through this process are comparable to other more expensive manufacturing methods such…

Surface and center temperature of the mushroom, ambient humidity and temperature of vacuum chamber have been measured and recorded by the data logger inside the vacuum chamber (see Fig. 1).
