Explanation:
Actual search engines allow very advanced searches, using multiple words related with your objective will improve the results obtained. Also you can refine your search by using specific operators to include or exclude words, websites, file types or dates.
For example in Google search, using + and - will force the results to include and exclude respectively the following word. Typing several words between " (double quotes) will search specifically for that sentence, the same words and in the same order. Using filetype: will restrict results of a specific file extension, like jpg, or pdf.
There are many other operators available, you can find more information about this by looking for "advanced search operators" of your favourite search engine.
Isolation. Also is known as Lockout-Tagout. I hope this helps.
Answer:B. ARE UNCERTAIN FOR A STOCHASTIC MODEL.
Explanation:Stochastic model is a financial business model, often used by Business organisations to determine which financial decisions to make.
A stochastic model can also be described as a tool for evaluating the probability distributions of potential outcomes of certain events by giving room for random variation in one or more inputs per time. The random variation used in Stochastic model is usually relies on changes observed in historical data for a specific period of time using standard time-series techniques.
INPUT TO A QUANTITATIVE MODEL ARE UNCERTAIN FOR A STOCHASTIC MODEL.
Answer:
a) Yes
b) Yes
c) Yes
d) No
e) Yes
f) No
Explanation:
a) All single-bit errors are caught by Cyclic Redundancy Check (CRC) and it produces 100 % of error detection.
b) All double-bit errors for any reasonably long message are caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit. It also produces 100 % of error detection.
c) 5 isolated bit errors are not caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit since CRC may not be able to catch all even numbers of isolated bit errors so it is not even.
It produces nearly 100 % of error detection.
d) All even numbers of isolated bit errors may not be caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit. It also produces 100 % of error detection.
e) All burst errors with burst lengths less than or equal to 32 are caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit. It also produces 100 % of error detection.
f) A burst error with burst length greater than 32 may not be caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit.
Cyclic Redundancy Check (CRC) does not detect the length of error burst which is greater than or equal to r bits.
