How is Miss penalty calculated in cache? You can calculate the miss penalty in the following way using a weighted average: (0.5 * 0ns) + (0.5 * 500ns) = (0.5 * 500ns) = 250ns . Now, suppose you have a multi-level cache i.e. L1 and L2 cache. Hit time now represents the amount of time […]
What is the difference between Butterworth Chebyshev I and Chebyshev II filters?
What is the difference between Butterworth Chebyshev I and Chebyshev II filters? Butterworth filter has a poor roll-off rate. For the same filter order, the stopband attenuation is higher for the Chebyshev filter. Compared to a Butterworth filter, a Chebyshev-I filter can achieve a sharper transition between the passband and the stopband with a lower […]
What does not affect stopping distance?
What does not affect stopping distance? Visibility is one of a number of factors that do not affect your braking distance per se but can inhibit your thinking distance. The longer it takes for you to spot hazards in the road, the more time will have passed before you hit the brake pedal. What will […]
What happens to the workpiece if the cutting tool is dull?
What happens to the workpiece if the cutting tool is dull? There are many effects of performing a cutting operation with a dull tool. Note that a dull tool has an increased tip radius (see Fig. 21.22 on p. 636); as the tip radius increases (the tool dulls), the cutting force increases due to the […]
How do you perform a risk assessment?
How do you perform a risk assessment? Risk assessments can be daunting, but we’ve simplified the process into seven steps: Define your risk assessment methodology. Compile a list of your information assets. Identify threats and vulnerabilities. Evaluate risks. Mitigate the risks. Compile risk reports. Review, monitor and audit. How much does a security risk assessment […]

Explanation: There are many safety precautions to consider when preparing for a recreational outing, among it are the weather if the destination, the amount of water you are going with, the equipment and […]
Does thermal conductivity depend on temperature?
Does thermal conductivity depend on temperature? The effect of temperature on thermal conductivity is different for metals and nonmetals. In metals, heat conductivity is primarily due to free electrons. In alloys the change in electrical conductivity is usually smaller and thus thermal conductivity increases with temperature, often proportionally to temperature. What is the temperature dependence […]
How do you solve a problem?
How do you solve a problem? Here are seven-steps for an effective problem-solving process. Identify the issues. Be clear about what the problem is. Understand everyone’s interests. List the possible solutions (options) Evaluate the options. Select an option or options. Document the agreement(s). Agree on contingencies, monitoring, and evaluation. How do you solve a problem […]
What number does the Lucas sequence approach?
What number does the Lucas sequence approach? Definition. Similar to the Fibonacci numbers, each Lucas number is defined to be the sum of its two immediate previous terms, thereby forming a Fibonacci integer sequence. The first two Lucas numbers are L0 = 2 and L1 = 1 as opposed to the first two Fibonacci numbers […]
Which of the following quenching media is most severe in its quenching action?
Which of the following quenching media is most severe in its quenching action? Different quenching media have different degrees of severity. Caustics are the most severe quenchants, followed by oils, then salts and, finally, gases. Which quenching media gives the fastest cooling? Brine. Brine is a mixture of water and salt. Brine cools faster than […]
