describe how the visual system has evolved to perceive edges. include the research of hubel & wiesel, contrast enhancement, and surface interpolation in your discussion. chegg

Answers

Answer 1

The visual system has evolved to perceive edges in order to efficiently and accurately identify objects in the environment. This ability to detect edges has been studied extensively by neuroscientists.

Hubel and Wiesel found that cells in the visual cortex of cats and monkeys respond to specific features of visual stimuli, such as orientation, movement, and spatial frequency. They discovered that certain neurons in the primary visual cortex, called simple cells, respond best to edges of specific orientations. These cells are arranged in columns that are sensitive to different orientations, creating a map of the visual field in the brain.

One way that the visual system enhances the perception of edges is through contrast enhancement. This is achieved by increasing the contrast between adjacent regions of different luminance levels, making edges more salient. This process is thought to be mediated by cells in the retina and lateral geniculate nucleus (LGN) that respond best to differences in light intensity.

True or false :roughly half of major companies in the u.s. sometimes monitor the email or voice mail of their employees on company systems

Answers

It is true. About half of the largest U.S. corporations occasionally check their employees' voicemail or email on company systems.

In general, emails sent or received through business email accounts are not regarded as private. As long as there is a legitimate business justification, employers are authorized to monitor these interactions. Many businesses support this right by informing staff members in writing—for instance, in an employee handbook—that company email is not private and that it is being monitored. Even if your organization doesn't have a formal email policy of this sort, it is likely still within its legal rights to access employee email communications sent from work accounts.

On the other hand, your corporation may have limited its ability to monitor these interactions if it takes proactive measures to preserve the privacy of employee emails.

Write a java expression to give a substring of s with the center character removed

Answers

The Java expression to obtain a substring from a string 's' with the central character removed is `s.substring(0, s.length()/2) + s.substring(s.length()/2 + 1)`.

This solution assumes that the string 's' has an odd length.

To explain further, the above Java expression works by first using the `substring` method to take the substring from the start of the string to the character just before the middle, and then concatenating this with the substring from the character just after the middle to the end of the string. The `substring` method in Java is used to extract a sequence of characters from a string. It can take two parameters: the starting index, which is inclusive, and the ending index, which is exclusive. Here, the string's length is divided by two to find the index of the middle character for odd-length strings. This middle character is then string manipulation in Java from the resulting substring.

An attacker has obtained the logon credentials for a regular user on your network. Which type of security threat exists if this user account is used to perform administrative functions

Answers

Answer:

privilege escalation.

Explanation:

An access control can be defined as a security technique use for determining whether an individual has the minimum requirements or credentials to access or view resources on a computer by ensuring that they are who they claim to be.

Simply stated, access control is the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.

Basically, authentication and authorization is used in access control, to ensure a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification

Hence, an access control list (ACL) primarily is composed of a set of permissions and operations associated with a user account or new technology file system (NTFS) file such as full control, read only, write, read and execute and modify.

In this scenario, an attacker or hacker was able to obtain the logon credentials for a regular user on your network. Thus, the type of security threat which exists if this user account is used by the attacker or hacker to perform administrative functions is privilege escalation.

Privilege escalation can be defined as a network or security threat which involves the exploitation of a design flaw, bug or unsecured configuration settings in a software program (application), operating system (OS), computer system, etc., so as to have an unauthorized access and gain more permissions, elevated rights or privileges that are normally protected from a user account or software program.

Hence, when an attacker or malicious user such as a hacker gains an unauthorized access to the privileges of another user account beyond what is intended or entitled to a user, it is known as privilege escalation.

A credit card company receives numerous phone calls throughout the day from customers reporting fraud and billing disputes. Most of these callers are put "on hold" until a company operator is free to help them. The company has determined that the length of time a caller is on hold is normally distributed with a mean of 2.5 minutes and a standard deviation 0.5 minutes. If 1.5% of the callers are put on hold for longer than x minutes, what is the value of x? Use Excel, and round your answer to two decimal places.

Answers

Answer:

3.59 minutes

Explanation:

We solve this question using z score formula

Using Excel

Z-SCORE= (DataPoint-AVERAGE(DataSet))/STDEV(DataSet)

IN EXCEL,

AVERAGE, an excel function that calculates the Average of data set

STDEV.S: calculates the standard deviation while treating the data as a ‘sample’ of a population.

STDEV.P: This function calculates the standard deviation while treating the data as the entire population.

Z score formula = x - μ/σ

x = ?? μ = 2.5 minutes σ = 0.5 minutes

We are asked : If 1.5% of the callers are put on hold for longer than x minutes, what is the value of x?

Hence, Longer than = Greater than =

100 - 1.5%

= 100 - 0.015

= 0.985 ( 98.5%)

Using Excel we calculate = z score for 98.5 percentile

= 2.1701

Z score = x - μ/σ

2.1701 = x - 2.5/0.5

2.1701 × 0.5 = x - 2.5

1.08505 = x - 2.5

x = 1.08505 + 2.5

x = 3.58505

Approximately to 2 decimal places = 3.59 minutes

Therefore, 1.5% of the callers are put on hold for longer than 3.59 minutes.

In this situation, granular application of policies and higher security are not direct consequences of having a single DNS zone, and thus do not apply.

If the organization continues with a single DNS zone for the entire organization spanning multiple geographical locations, the following are likely to happen:

1. Name resolution traffic goes to the single zone: All name resolution requests from all the geographical locations will be directed to the single DNS zone. This may lead to increased network traffic, which could affect the performance of the network.

2. Granular application of policies: It may become difficult to apply granular policies for specific geographical locations or departments. This could lead to inconsistencies in policy enforcement.

3. Centralized Management: The organization can benefit from centralized management of the DNS zone. This would enable easy management of the zone and ensure consistency in policy enforcement.

4. Higher security: A single DNS zone may lead to higher security risks as any security breaches in the zone could affect the entire organization.

5. Administrative burden: Maintaining a single DNS zone for the entire organization may result in increased administrative burden, especially if the organization is large or spread across multiple geographical locations.

What is the best way to test code?

Answers

The best way to test code is through a combination of unit tests, integration tests, and automated testing frameworks.

The best way to test code is through a combination of various testing techniques and strategies. A comprehensive testing approach typically involves unit tests, integration tests, and the use of automated testing frameworks.

Unit tests are designed to test individual units or components of code in isolation. These tests focus on specific functions, methods, or classes, verifying that they behave correctly and produce the expected output for a given set of inputs. Unit tests help catch bugs and ensure that each piece of code functions as intended.

Integration tests, on the other hand, examine how different components of a system work together. They test the interaction between various modules or services to ensure seamless integration and identify any compatibility issues. Integration tests are valuable in detecting issues that may arise when multiple components interact, such as data flow, API communication, and dependencies.

Automated testing frameworks provide a structured approach to testing by automating the execution of tests and generating reports. These frameworks streamline the testing process, enable easy maintenance of test suites, and allow for regression testing to catch potential issues introduced during code changes. They also provide code coverage metrics, which help evaluate the effectiveness of testing efforts.

By combining unit tests, integration tests, and utilizing automated testing frameworks, developers can ensure that their code is thoroughly tested, reducing the likelihood of bugs and improving the overall quality of the software.

Additionally, incorporating continuous integration and continuous delivery (CI/CD) practices further enhances the testing process by automatically running tests whenever new code changes are introduced, providing rapid feedback and allowing for quick bug detection and resolution.

explore the data frame, identify and report the missing data. how will you deal with the missing data?

Answers

To identify missing data in a data frame, you can check for null values or use visualization techniques. Dealing with missing data can involve approaches such as deletion, imputation, or using categorical indicators, depending on the extent and nature of the missing values.

To explore a data frame and identify missing data, you can use various techniques such as checking for null values, visualizing missing data patterns, or using summary statistics.

Once the missing data is identified, you can employ different strategies to deal with it. Here are some common approaches:

1. Deleting Rows or Columns: If the missing data is minimal or doesn't significantly affect the analysis, you may choose to delete the rows or columns containing missing values. However, this approach should be used cautiously to ensure that valuable information is not lost.

2. Imputation: Missing values can be replaced with estimated or predicted values based on other data points. This can be done through mean, median, mode imputation, or using more advanced techniques like regression or machine learning algorithms.

3. Categorical Indicator: If missing values occur in categorical variables, you can create a separate category or indicator variable to represent missing data. This allows the missingness to be explicitly accounted for in the analysis.

4. Multiple Imputation: In cases where missing data is more extensive, multiple imputation methods can be employed. This involves creating multiple imputed datasets, filling in missing values using statistical models, and combining the results to obtain more accurate estimates.

5. Domain Knowledge: Depending on the context and the reason for missing data, domain knowledge can help inform the best approach.

For instance, if missing values are due to non-response in a survey, understanding the survey process and potential biases can guide imputation techniques.

The choice of how to deal with missing data depends on factors like the amount of missing data, the nature of the variables, the goals of the analysis, and assumptions made about the missingness.

It is important to carefully consider the impact of each method and the potential biases introduced to ensure the validity and reliability of the analysis.
