problem-oriented policing.
/
Problem-oriented policing (POP) is a policing strategy that aims to identify and prevent the underlying causes of criminal behavior. It is a proactive approach to policing that aims to reduce crime and disorder by addressing the root causes of problems in the community.
Pop was introduced by Herman Goldstein, a law professor at the University of Wisconsin-Madison, in 1979. It gained popularity in the 1990s as an alternative to traditional policing methods, which focused on responding to crime rather than preventing it. Problem-oriented policing is based on the idea that crime is not a random occurrence but is rather the result of specific underlying problems that can be identified and addressed.
The success of problem-oriented policing depends on a number of factors, including the quality of problem analysis, the effectiveness of the strategies developed to address the underlying causes of crime, and the level of collaboration between the police department and other agencies in the community. When implemented effectively, problem-oriented policing can be an effective strategy for reducing crime and disorder in communities.

Select all that apply. Which of the following problems can be solved using recursion?
a. computing factorials
b. finding the greatest common divisor of two numbers
c. doing a Binary Search
d. multiplying two numbers
e. traversing a linked list
The problems that can be solved using recursion are:
a. Computing factorials
b. Finding the greatest common divisor of two numbers
c. Doing a Binary Search
e. Traversing a linked list
Recursion is a problem-solving technique where a function calls itself to solve a smaller subproblem of the original problem. It is particularly useful for solving problems that can be broken down into smaller, similar subproblems.
In the case of computing factorials, the factorial of a number can be defined recursively as the product of that number and the factorial of its predecessor. Finding the greatest common divisor (GCD) of two numbers can be approached recursively using the Euclidean algorithm. The GCD of two numbers is the largest number that divides both of them without leaving a remainder. The algorithm repeatedly applies the property that the GCD of two numbers is equal to the GCD of one of the numbers and the remainder of their division. Binary search is a recursive algorithm that efficiently searches for a target value in a sorted array or list by repeatedly dividing the search space in half. Traversing a linked list can also be done recursively by visiting each node and recursively moving to the next node until the end of the list is reached.

After the code fragment runs, the value in the variable xyz will contain s.end(). If you resize a std::list from having 3 elements to having 6, three new elements will be constructed using the default constructor for the type of elements contained in the list and placed at the end of the list. Valid ways to create a stack include std::stack<int> st. The source-code for the methods of a template class typically goes in the .h file along with the class declaration.
1. After the code fragment runs, the value in the variable xyz will contain s.end().
The std::set container stores its elements in a sorted order, and the find() function in this code is searching for the element with the value 123.456. However, none of the inserted elements have a value of 123.456. In such cases, the find() function returns an iterator pointing to the position just after the last element in the container, which is obtained by calling s.end(). Therefore, the value of xyz will be s.end().
2. If you resize a std::list from having 3 elements to having 6, three new elements will be constructed using the default constructor for the type of elements contained in the list and placed at the end of the list.
Resizing a std::list involves changing the number of elements it contains. When increasing the size from 3 to 6, the additional elements need to be created. In this case, the default constructor for the type of elements stored in the list will be called three times to construct three new elements. These new elements will then be appended to the end of the list, resulting in a total of 6 elements.
3. Valid ways to create a stack include std::stack<int> st.
To create a stack, you can use the std::stack container adapter. The provided code snippet demonstrates the correct way to create a stack by using std::stack<int> st. This creates a stack of integers (int type). The std::stack container adapter provides a convenient interface for working with a stack data structure, including operations like push(), pop(), and top().
4. The source-code for the methods of a template class typically goes in the .h file along with the class declaration.
In C++, when working with template classes, it is common to include the implementation (source code) of the template class methods within the same file as the class declaration. Conventionally, this file has the extension .h and contains both the class declaration and the implementation. This approach is taken because templates need to be visible to the compiler at the point of instantiation, and including the implementation in the .h file allows the necessary code to be readily available during compilation. However, it's important to note that alternative approaches, such as separating the implementation into a separate .cpp file, can also be used depending on the project's requirements and design choices.

( 3 pts.) 1.2 If we store the data file in MySQL, how many blocks or pages that need for the storing? (2 pts.) (Note. Each record is a fixed length record.).
The number of blocks or pages needed to store the data file in a hard drive can be calculated by dividing the total size of the data file by the block size.
Size of each record = Size of Id (2 bytes) + Size of Name (16 bytes) + Size of Age (2 bytes) + Size of Phone (bytes) = 2 + 16 + 2 + (bytes)
Total size of the data file = Size of each record * Number of records = (2 + 16 + 2 + bytes) * 1000
Number of blocks or pages needed = Total size of the data file / Block size
1.2 If we store the data file in MySQL, the number of blocks or pages needed would depend on the storage engine being used and its internal organization. In general, MySQL uses its own storage management system to allocate disk space for storing data files. The exact calculation of blocks or pages would depend on various factors such as indexes, data types, and storage engine-specific optimizations.

Operating Systems
3. (8) How does the operating system regain control of the CPU after allowing an application process to run? 4. (8) What items are part of a process's machine state?
When the operating system allows an application process to run, it regains control of the CPU through interrupt handling and context switching. The machine state of a process includes the program counter, registers, memory allocation, and stack.
To regain control of the CPU after allowing an application process to run, the operating system relies on interrupt handling and context switching. Interrupts are signals generated by hardware or software events that cause the CPU to temporarily suspend its current execution and transfer control to the operating system. Interrupt handling routines within the operating system process these interrupts, performing necessary tasks such as handling I/O operations or responding to system calls. During a context switch, the operating system saves the machine state of the running process, including the program counter (which indicates the next instruction to be executed), registers (containing temporary data and variables), memory allocation (such as the heap and stack), and other relevant information.
It then restores the saved machine state of a different process, allowing it to continue execution. By leveraging interrupt handling and context switching, the operating system can efficiently schedule and manage multiple processes, providing each application with its fair share of CPU time while ensuring system stability and responsiveness.

To calculate the call blocking probability (B) using the Erlang fixed-point approximation approach, we need to use the method of successive substitution.
Let's start with an initial guess of θ=180 calls/minute and a tolerance limit of 0.1%. We can use the Erlang B table to find the corresponding B value for each iteration. Now, let's complete the table step by step: Iteration 1: θ = 180 calls/minute (initial guess) Using the Erlang B table, we find that for θ=180 and C=280, B=0.138.
Iteration 2: θ = 120 calls/minute (average call arrival rate) Using the Erlang B table, we find that for θ=120 and C=280, B=0.057.
Since the difference between the B values of the last two iterations is less than the tolerance limit (0.1%), we can consider the calculation complete. The call blocking probability (B) for the given cellular system is approximately 0.057.

The provided code includes a Java program that demonstrates the implementation of the bubble sort algorithm to order elements in an array. It also includes methods to populate the array with random, ordered, and inverse sorted data.
The program measures the runtime and the number of swaps required for sorting a large array in each scenario. The BubbleSortApp class serves as the main entry point for executing the program.
The ArrayBub class represents an array-based data structure and provides methods for inserting elements into the array, displaying the array contents, and performing the bubble sort algorithm. The bubble sort algorithm implemented in the bubbleSort() method compares adjacent elements and swaps them if they are in the wrong order, repeating this process until the array is sorted.
The BubbleSortApp class utilizes an instance of ArrayBub and demonstrates the sorting of a large array with 100,000 elements. It includes methods to populate the array with random data (insertRandomData()), inverse sorted data (sortLargeInverseArray()), and ordered data (sortLargeOrderedArray()).
In the main() method, the BubbleSortApp instance is created, and the sorting methods are called sequentially. The program measures the runtime using System.currentTimeMillis() before and after the sorting process, and calculates the number of swaps performed during the sorting.
By running the program, one can observe the differences in runtime and the number of swaps required for sorting different types of data. The inverse sorted data requires the most number of swaps and likely takes the longest time, while the ordered data requires no swaps but may still take some time due to the size of the array. The random data falls in between these two scenarios.

- Tentative lease terms call for payments of $475,000 at the end of each year.
- The best estimate for the value of the computer after three years of wear and tear is $300,000.
What is the NAL of the lease? Format is $xx,x×x.x×x or ($x×,x×x,x×x)
What is the IRR of the lease? Format is x.xx% or (x.xx)%
Should the organization buy or lease the equipment? Format is Buy or Lease
The HCA must install a new $1.4 million computer to track patient records in its multiple service areas. It plans to use the computer for only three years, at which time a brand new system will be acquired that will handle both billing and patient records.
It can obtain a 10% bank loan to buy the computer or it can lease the computer for three years.The initial outlay in case of leasing the computer would be the present value of the payment stream; the final payment is paid at the end of Year 3, so it is discounted three years. Since the lease payment comes at the end of the year, an annuity due factor will be applied.
Using Excel to calculate the present value of lease payment at 10% rate, we get the present value of lease payments to be $1,129,192.98.Using MACRS allowances and marginal tax rate, we can calculate the tax savings associated with buying the computer instead of leasing. With the purchase of the computer,
the MACRS tax savings in Years 1-3 will be $477,320. Using the after-tax salvage value, the company’s net outlay is $782,802.Using these values, we can calculate the Net Advantage to Leasing (NAL)
We see that the NAL is -$277,171.88, indicating that it would be cheaper to purchase the computer instead of leasing it.IRRIRR = 14.12%.

Develop a C program to decode a secret word. Your program must create the function char GetCode(int codeNo). The GetCode function works as follows: If codeNo is 1, the function must start with the integer value 31. The program must then turn on bit 6 in that value and then turn off bit 3 in that value. Define two bit masks (symbolic constants) named BIT3 and BIT6 to represent the bit mask value for those bit positions (remember, the value for bit position b is 2b). The use those bit masks when turning the bits on and off. The resulting number should be returned as a char value (use a type cast). If codeNo is 2, the function must start with the integer value 2638. Then the program must read the value in bit positions 3 through 9. The AdjustTemp function for the Electronic Thermostat example in the notes reads the temperature (nTemperature) from bit positions 3 through 10 using the bit mask TEMP (0x7F8). Your code will be similar except the bit mask value is 0x3F8. The resulting number should be returned as a char value (use a type cast). If codeNo is 3, the function must start with the integer value -79. The program must complement the number. The resulting number should be returned as a char value (use a type cast). Your main() should call the GetCode function three times, passing the parameter values 1, 2, and 3. Each time the function is called, the function returns a char value. Once all three char values are obtained, your main() should print the three char values one after another (the char for codeNo 1 followed by the char for codeNo 2 followed by the char for codeNo 3) to display the secret word.
The program to decode a secret word is given below. The program must create the function char GetCode(int codeNo).
```c
#include <stdio.h>
// Bit masks for turning on/off specific bits
#define BIT3 (1 << 3)
#define BIT6 (1 << 6)
// Function to decode the secret word based on codeNo
char GetCode(int codeNo) {
int value;
if (codeNo == 1) {
value = 31;
value |= BIT6; // Turn on bit 6
value &= ~BIT3; // Turn off bit 3
} else if (codeNo == 2) {
value = 2638;
value = (value >> 3) & 0x3F; // Read bits 3 to 9
} else if (codeNo == 3) {
value = -79;
value = ~value; // Complement the number
} else {
printf("Invalid codeNo\n");
return '\0'; // Return null character if codeNo is invalid
}
return (char)value; // Type cast the resulting number as a char
}
int main() {
char secretWord[4];
secretWord[0] = GetCode(1);
secretWord[1] = GetCode(2);
secretWord[2] = GetCode(3);
secretWord[3] = '\0'; // Null-terminate the string
printf("Secret Word: %s\n", secretWord);
return 0;
}
```
1. The program defines two symbolic constants `BIT3` and `BIT6` to represent the bit mask values for bit positions 3 and 6.
2. The `GetCode` function takes an `int` parameter `codeNo` to determine the code number for decoding the secret word.
3. Inside the `GetCode` function, different code number cases are handled using conditional statements (`if`, `else if`, and `else`).
4. For `codeNo` equal to 1, the function starts with the integer value 31. It then turns on bit 6 and turns off bit 3 by applying the bit masks `BIT6` and `~BIT3` using the bitwise OR (`|`) and bitwise AND (`&`) operators, respectively.
5. For `codeNo` equal to 2, the function starts with the integer value 2638. It then reads the bits from positions 3 to 9 by shifting the value to the right by 3 bits (`value >> 3`) and applying the bit mask `0x3F` using the bitwise AND (`&`) operator.
6. For `codeNo` equal to 3, the function starts with the integer value -79. It complements the number by applying the bitwise NOT (`~`) operator.
7. Finally, the resulting number is type casted as a `char` and returned from the `GetCode` function.
8. In the `main` function, the `GetCode` function is called three times with code numbers 1, 2, and 3. The resulting characters are stored in the `secretWord` array.
9. The `secretWord` array is printed using `printf`, displaying the decoded secret word.

Feature engineering is the process of adjusting the representation of the data to improve the efficacy of the model. In time series, data scientists construct the output of their model by identifying the variable that they need to predict at a future time (ex: future energy demand or load next month) and then leverage historical data and feature engineering to create input variables that will be used to make predictions for that future date.
For this activity, in 500-750 words, answer the following:
Discuss the main goals/benefits of performing feature engineering on Time-Series data.
Perform the following types of Features on your selected time-series dataset and report the results of each:
- Date Time Features: from the Date column, "Feature Extract" three additional columns to your data frame: one for the Year, one for the Month, and one for the Day. Show the results.
- Lag Features: use the shift function to "Feature Extract" three additional columns: same day last week, same day last month, same day last year. Show the results.
- Window Features: Use the rolling method to "Feature Extract" an additional column that shows a 2-month rolling average. Show the results.
- Expanding Feature: here, we're not considering window size. We want to consider all the values in the data frame. Use the expanding method to "Feature Extract" an additional column that shows the maximum value till date. Show the results of the data frame.
Discuss some additional insights you gained from leveraging the additional knowledge you performed in the previous step. How can this help you build a better time series forecasting solution as a data scientist?
"Feature Extract" an additional column called "Q" to show the quarterly data of your data frame by using the resample function. Show the results. Hint: call the mean of the resample function.
Perform the same step you did in step 4, but show the Yearly data in this step.
Feature engineering in time series data involves adjusting the data representation to improve the effectiveness of modeling. It aims to enhance predictive performance, interpretability, and the ability to handle seasonality, trends, non-stationarity, and external factors. In the provided activity, date time features, lag features, window features, expanding features, and resampling techniques were applied to a time series dataset.
Performing feature engineering on time series data offers several goals and benefits:
Improved Predictive Performance:
Feature engineering helps in creating informative and relevant features that capture important patterns and relationships in the data. By incorporating domain knowledge and designing appropriate features, the model can better capture the underlying patterns and improve its predictive performance.Increased Model Interpretability:
Feature engineering allows data scientists to create features that are easily interpretable and align with the problem domain. This helps in understanding the relationships between the features and the target variable, providing insights into how the model is making predictions.Handling Seasonality and Trends:
Time series data often exhibit seasonality and trends, which can impact the accuracy of predictions. Feature engineering techniques such as lag features and rolling averages can help capture and incorporate these patterns into the model, enabling it to make more accurate predictions.Handling Non-Stationarity:
Time series data may have non-stationary properties, where the statistical properties change over time. Feature engineering techniques such as differencing or detrending can help transform the data into a stationary form, making it more amenable to modeling.Incorporating External Factors:
Time series data is often influenced by external factors such as holidays, weather conditions, or economic indicators.
Feature engineering allows for the inclusion of these external factors as additional features, which can enhance the model's predictive power by capturing their impact on the target variable.
The specified feature engineering steps on the selected time series dataset:
1. Date Time Features:
Create three additional columns: Year, Month, and Day, extracted from the Date column.Show the results.2. Lag Features:
Create three additional columns: Same day last week, same day last month, and same day last year.Use the shift function to shift the values accordingly.Show the results.3. Window Features:
Create an additional column: 2-month rolling average.Use the rolling method to calculate the rolling average.Show the results.4. Expanding Feature:
Create an additional column: Maximum value till date.Use the expanding method to calculate the expanding maximum.Show the result.5. Additional Insights:
By leveraging the additional knowledge gained from feature engineering, we can observe the following insights:The lag features provide information about how the current day's value compares to the corresponding day in the previous week, month, and year.The window feature of a 2-month rolling average helps smooth out short-term fluctuations and provides a trend of the data.The expanding feature of the maximum value till date gives an indication of the overall upward or downward trend in the data.6. Quarterly Data:
Create an additional column called "Q" to show the quarterly data.Use the resample function and calculate the mean for each quarter. Show the results.7. Yearly Data:
Create an additional column called "Yearly" to show the yearly data.Use the resample function and calculate the mean for each year.Show the results.These additional features and insights obtained through feature engineering can help build a better time series forecasting solution:
The lag features capture seasonality and temporal dependencies, providing the model with valuable historical information for making predictions.The window feature smoothes out short-term fluctuations, allowing the model to focus on the overall trend of the data.The expanding feature considers the entire data history, enabling the model to understand the overall behavior and extreme values.Quarterly and yearly data provide a higher-level perspective, helping to identify long-term patterns and trends.By incorporating these features into the forecasting model, data scientists can enhance its ability to capture complex patterns, improve accuracy, and make more reliable predictions for future time points.

If its motion has a constant, but non zero acceleration, please indicated the magnitude and direction of the acceleration.
Regarding the motion of the ball in the x direction (horizontal), if there is no air resistance, the ball will have a constant velocity (zero acceleration) in the x direction. This is because there are no forces acting horizontally to change its speed or direction.
In the y direction (vertical), the ball will experience a constant, but non-zero acceleration due to the force of gravity. The acceleration due to gravity is approximately 9.8 m/s² directed downward. This means that the ball will accelerate downward with a magnitude of 9.8 m/s² throughout its motion in the y direction. acceleration: the rate at which the speed and direction of a moving object vary over time.

Suppose we are working with an error-correcting code that will allow all single-bit errors to be corrected for memory words of length 10. How long should the check bits and why?
The length of the check bits should be 4.
To allow for the correction of all single-bit errors in memory words of length 10, we need to use an error-correcting code with sufficient check bits. The check bits are additional bits added to the data bits to detect and correct errors.
In this case, we need to determine the number of check bits required to detect and correct all single-bit errors. To do so, we can use the concept of Hamming distance.
The Hamming distance between two code words is the number of positions at which the corresponding bits are different. For a code to correct single-bit errors, the minimum Hamming distance should be at least 3. This ensures that if a single bit error occurs, the received code word will be closer to the correct code word than to any other code word.
To determine the number of check bits required, we can use the formula:
2^r ≥ n + r + 1
where r is the number of check bits and n is the number of data bits. In this case, we have a memory word of length 10, so n = 10.
Let's substitute the values and solve for r:
2^r ≥ 10 + r + 1
We can start by trying different values of r until we find the smallest value that satisfies the inequality:
For r = 3:
2^3 = 8 ≥ 10 + 3 + 1
8 ≥ 14 (not satisfied)
For r = 4:
2^4 = 16 ≥ 10 + 4 + 1
16 ≥ 15 (satisfied)
Therefore, the minimum number of check bits required to allow for the correction of all single-bit errors in memory words of length 10 is 4.

what is object oriented approach in regard to develop computer systems ?
The object-oriented approach in computer systems development organizes code based on objects and classes, promoting encapsulation, inheritance, and code reuse for efficient and scalable software development.
1. In the object-oriented approach, a class is a blueprint or template that defines the properties (attributes) and behaviors (methods) of an object. Objects are created from classes, and they encapsulate data and related functionality within a single entity. Objects can communicate with each other by invoking methods and exchanging data.
2. The key principles of the object-oriented approach include which helps in developing computer systems:
Encapsulation: Objects encapsulate data and behavior together, hiding the internal details and exposing a well-defined interface.Inheritance: Classes can inherit properties and behaviors from other classes, forming an "is-a" relationship. This promotes code reuse and allows for the creation of hierarchical relationships between classes.Polymorphism: Objects of different classes can be treated interchangeably through a common interface, allowing flexibility and extensibility in the system design.Abstraction: Abstraction involves simplifying complex systems by representing essential features and hiding unnecessary details.
