Answers

Answer 1

The main answer to your question is that Johnson uses the term "exaptation" to describe where an object or process is applied in a new way because its capabilities are useful. Exaptation refers to the adaptation of a biological trait for a different purpose than what it originally evolved for.

Johnson extends this concept to non-biological systems, such as technology, to explain how objects or processes can be repurposed for different uses based on their inherent capabilities. In your example, punch cards were originally designed for weaving patterns, but their ability to store and process information was exapted for use in early computer programming. Overall, this is a LONG ANSWER to your question that highlights how the concept of exaptation can be applied to various fields, including technology.Your question is: What is the biological term used by Johnson to describe where an object or process is applied in a new way because its capabilities are useful, such as punch cards used for weaving being used for early computer programming?

The biological term you are looking for is "exaptation." Exaptation is a concept in evolutionary biology that describes when a trait, feature, or process developed for one purpose is co-opted or adapted for a new and different purpose. This can occur in biological evolution, as well as in the development of human technologies, such as the punch cards example you provided. In the context of your example, punch cards initially had the purpose of controlling weaving patterns in looms. However, their capabilities were later applied in a new way for early computer programming, making it an example of exaptation. Exaptation demonstrates the ability of innovations to be adapted and used in new contexts, contributing to further advancements in technology and other fields.

for machine m with cpu of 850 mhz, we just added another cpu with the same speed. assuming 50 % of instructions must be executed sequentially, what is the speedup of machine m?

Answers

The speedup calculation takes into account the proportion of instructions that can be executed in parallel and the number of processors, resulting in a faster execution time.

Adding another CPU with the same speed to machine m with a CPU of 850 MHz would result in a speedup for the machine. Assuming 50% of instructions must be executed sequentially, the speedup can be calculated using Amdahl's Law. Amdahl's Law states that the speedup of a program is limited by the portion of the program that cannot be parallelized. In this case, the portion that cannot be parallelized is 50% of the instructions. The speedup can be calculated as follows:

Speedup = 1 / (1 - (portion that can be parallelized + portion that cannot be parallelized / number of processors))

Plugging in the values, we get:

Speedup = 1 / (1 - (0.5 + 0.5 / 2)) = 1.67

Therefore, the speedup of machine m would be 1.67 after adding another CPU with the same speed.

concentration of the salt in the tank in grams/litre, when the tank contains 350 litres of solution?

Answers

The concentration of salt in the tank, when it contains 350 liters of solution, is approximately 3.43 grams per liter.

To determine the concentration of salt in the tank when it contains 350 liters of solution, we can use the concept of mass balance. The rate of salt entering the tank is given by the concentration of the incoming solution (3 grams/liter) multiplied by the flow rate (5 liters/minute), which gives us an inflow rate of 15 grams/minute. The rate of salt leaving the tank is given by the concentration of the tank solution (unknown) multiplied by the flow rate (4 liters/minute), which gives us an outflow rate of 4 times the concentration of salt in the tank (in grams/minute).

Initially, the tank contains 300 liters of solution with a salt concentration of 4 grams/liter. Over time, the salt concentration in the tank will change as the inflow and outflow occur. Let's denote the salt concentration in the tank as C grams/liter. Using the mass balance equation, we can write:

Inflow rate = Outflow rate

15 grams/minute = 4 times C grams/minute

Simplifying the equation, we find:

C = 15/4 = 3.75 grams/liter

Therefore, the concentration of salt in the tank, when it contains 350 liters of solution, is approximately 3.43 grams per liter (calculated as 15/4 ≈ 3.75 grams/liter).

which of the following describes the transfer risk response method

Answers

The transfer risk response method involves transferring the risk of a potential negative event to a third party. This is done by purchasing insurance, outsourcing a task to a vendor, or entering into a contractual agreement that shifts the responsibility for the risk to another party.

The transfer risk response method is one of the several methods that organizations use to respond to risks. It involves transferring the risk to a third party, such as an insurance company, a vendor, or another organization. The objective of the transfer risk response method is to reduce the impact of the potential negative event on the organization by shifting the responsibility for managing the risk to a party that is better equipped to handle it.

One common way to transfer risk is through purchasing insurance. Insurance policies can cover a wide range of risks, from property damage to liability claims, and they provide financial protection to the organization in case of a loss. The organization pays premiums to the insurance company, and in exchange, the insurance company agrees to pay for any losses that fall within the policy's coverage. This method of risk transfer is commonly used by organizations to mitigate the financial impact of potential losses. Another way to transfer risk is through outsourcing tasks to vendors or contractors. By outsourcing, the organization shifts the responsibility for the risk associated with the outsourced task to the vendor. For example, an organization might outsource its IT infrastructure management to a third-party vendor, who would then be responsible for managing the risk associated with maintaining the IT infrastructure. This method of risk transfer is often used when the organization does not have the expertise or resources to manage the risk internally. Lastly, organizations can also transfer risk through contractual agreements. For example, a construction company might enter into a contract with a client that includes a clause that transfers the risk of project delays to the client. By doing so, the construction company reduces its exposure to the risk of project delays, as the client is now responsible for managing the risk. This method of risk transfer is often used in industries where contracts are a common part of doing business. In summary, the transfer risk response method involves shifting the responsibility for managing a potential negative event to a third party. This can be done through purchasing insurance, outsourcing tasks to vendors or contractors, or entering into contractual agreements that transfer the risk to another party. By using this method, organizations can reduce their exposure to risk and mitigate the potential impact of a negative event. the transfer risk response method is a risk management technique where the responsibility and ownership of a risk are shifted to another party, such as through insurance or outsourcing.

Answers

Algorithm 1, known as Hoare-partition, is a partitioning algorithm based on the decremental design and designed by Hoare. The algorithm takes an array A, a starting index p, and an ending index r as input and partitions the array into two parts based on a pivot element x.

In the first line of the algorithm, the pivot element x is selected as A[p]. Then, two indices, i and j, are initialized to p-1 and r+1, respectively. The algorithm enters a loop where j is decremented until an element A[j] less than x is found. Similarly, i is incremented until an element A[i] greater than x is found. Once i and j stop moving, the algorithm checks if i is less than j. If true, it means elements A[i] and A[j] are in the wrong partitions, so they are swapped. This process continues until i and j cross each other.

The algorithm effectively partitions the array into two parts: elements less than or equal to x on the left side and elements greater than x on the right side. The position where i and j cross each other marks the boundary between the two partitions. Overall, Hoare-partition algorithm follows a decremental design where it starts with two pointers moving inward from opposite ends of the array until they meet, swapping elements as necessary to create the desired partition.

valueerror empty vocabulary perhaps the documents only contain stop words

Answers

It seems that you are encountering a ValueError related to an empty vocabulary when processing documents.

This error usually occurs when the documents you are working with only contain stop words or no words at all. Stop words are common words that carry little meaningful information, such as "the", "and", or "in". Many text processing tools filter out stop words to focus on more significant words that better represent the content of the documents. If all the words in a document are stop words, the resulting vocabulary becomes empty, leading to the ValueError you mentioned.
To resolve this issue, you may want to consider the following steps:
1. Check your documents to ensure they contain meaningful content with more than just stop words.
2. Reevaluate the stop words list you are using. It might be too extensive, causing the removal of important words from the documents.
3. Modify your text processing pipeline to better handle cases with a high percentage of stop words or empty documents.
By addressing these points, you can improve the quality of your vocabulary and avoid the ValueError associated with an empty vocabulary. Remember that a robust and diverse vocabulary is crucial for accurate text analysis and understanding the context of the documents.

This is the most common option used to set the default language and character encoding for the system. However, it is worth noting that other options such as "LC_ALL" and "LC_*" can be used to override the default locale settings for specific applications or processes.

In general, setting the correct locale is important for ensuring that programs and applications display text and characters correctly and that date and time information is formatted correctly.
Which of the following options is passed to the Linux kernel from the GRUB2 configuration file to set the locale?

The correct option for setting the locale in the GRUB2 configuration file is "LANG". The other options, such as LC_*, LC_ALL, and TZ, are not used for this purpose in the GRUB2 configuration file.
Here's a step-by-step explanation:
1. Open the GRUB2 configuration file using a text editor, like nano or vim.
2. Locate the line that starts with "GRUB_CMDLINE_LINUX_DEFAULT".
3. To set the locale, add the "LANG" parameter followed by the desired locale code. For example, to set the locale to US English, add "LANG=en_US.UTF-8".
4. Save the changes and close the text editor.
5. Update the GRUB configuration by running the "update-grub" command as a superuser.
6. Reboot the system for the changes to take effect.

Queries based on more than one table, must have a common field. The correct answer is A.


When working with queries that involve more than one table, it is important to have a common field between the tables in order to join them together and retrieve the desired data. This common field acts as a link between the tables and allows the query to combine data from both tables into a single result set.

If you have a database with one table containing customer information and another table containing order information, you might want to create a query that shows all the orders for a particular customer. To do this, you would need to join the two tables on a common field such as customer ID, which is present in both tables.

The following function should swap the values contained in two integer variables, num1 and num2. What, if anything, is wrong with this function?
void swap(int num1, int num2)
{
int temp = num2;
num2 = num1;
num1 = temp;
}

Answers

The issue with the given swap function is that it does not correctly swap the values of the two integer variables num1 and num2 because it is not using pointers or references.

This issue is that passing variables by value means that the function creates a copy of the variable in a new memory location, and any changes made to the copy do not affect the original variable. To actually swap the values of the two variables, the function should instead accept the addresses of the variables (i.e. pointers) and dereference them to access the original variables and swap their values.

When the function is called, it passes the values of num1 and num2 by value, meaning it creates a copy of the variables in the function's scope. As a result, the changes made inside the function do not affect the original variables. To fix this, you should pass the variables by reference or use pointers.

why would the add method return false? a. when the addition of a new item was not successful b. when there was a duplicate of the entry already in the bag c. when there was not a duplicate of the entry already in the bag d. when addition of a new item was successful

Answers

The add method returns false when it encounters a duplicate entry in the bag, which helps to maintain the uniqueness of items in the collection. The correct option is option b.

The add method is a common method used in programming to add new items to a collection such as a bag or a list. The add method can return a Boolean value to indicate whether the addition of a new item was successful or not. In some cases, the add method may return false. There are several reasons why the add method may return false.

Option a: The add method may return false when the addition of a new item was not successful. This could occur if there was an error in the code or if the collection is full and cannot accept any more items.

Option b: The add method may also return false when there was a duplicate of the entry already in the bag. This means that the item being added is already present in the collection and therefore cannot be added again.

Option c: On the other hand, if there was not a duplicate of the entry already in the bag, the add method may return true to indicate that the addition of a new item was successful.

Therefore, the add method can return false for different reasons, such as when the addition of a new item was not successful or when there was a duplicate of the entry already in the bag. The method may return true only when there was not a duplicate of the entry already in the bag and the addition of a new item was successful.
