Types of Errors: Detection and Minimization01:12

Types of Errors: Detection and Minimization

8.7K
Error is the deviation of the obtained result from the true, expected value or the estimated central value. Errors are expressed in absolute or relative terms.
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
Systematic or...

Detection of Gross Error: The Q Test

7.1K
When one or more data points appear far from the rest of the data, there is a need to determine whether they are outliers and whether they should be eliminated from the data set to ensure an accurate representation of the measured value. In many cases, outliers arise from gross errors (or human errors) and do not accurately reflect the underlying phenomenon. In some cases, however, these apparent outliers reflect true phenomenological differences. In these cases, we can use statistical methods...

Random and Systematic Errors

11.2K
Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...

Systematic Error: Methodological and Sampling Errors

8.7K
In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...

Propagation of Uncertainty from Systematic Error01:10

Propagation of Uncertainty from Systematic Error

1.4K
The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this...

Area of Science:

  • Computer Engineering
  • Reliability Engineering
  • Space Electronics

Background:

  • Electronic equipment in harsh environments like space faces radiation threats causing permanent and transient errors.
  • Transient errors, or soft errors, are more frequent than permanent ones and manifest as control flow errors (CFEs) or data errors.
  • Existing research often assumes operating system reliability, focusing on mitigating soft errors at hardware or application levels.

Purpose of the Study:

  • To investigate the impact of soft errors on operating system components.
  • To compare the vulnerability of operating system components to soft errors against application-level components.
  • To demonstrate the benefits of enhancing operating system resilience against soft errors.

Main Methods:

  • Investigated the effects of induced soft errors on various operating system components.
  • Compared the susceptibility of OS components to soft errors with that of typical application components.
  • Evaluated the system-level tolerance gained by improving OS component endurance.

Main Results:

  • Soft errors occurring within operating system components were found to negatively impact both the OS itself and associated applications.
  • Operating system components exhibit a significant vulnerability to soft errors.
  • Mitigating soft errors at the OS level demonstrably enhances the tolerance of both OS and application components.

Conclusions:

  • The operating system is not immune to soft errors and is a critical vulnerability point.
  • Enhancing the resilience of operating system components against soft errors is crucial for overall system reliability in radiation environments.
  • Increased tolerance in OS components directly translates to improved tolerance for applications running on the system.
