answer:1. Automatic Emergency Braking (AEB) - AEB is an advanced safety system that uses radar, cameras, and sensors to detect potential collisions with other vehicles or pedestrians. The system can automatically apply the brakes if it detects an imminent collision, helping to prevent or mitigate the severity of a crash. 2. Lane Departure Warning (LDW) - LDW uses cameras or sensors to monitor a vehicle's position on the road. If the system detects that the vehicle is drifting out of its lane, it can provide an audible or visual warning to the driver, helping to prevent unintentional lane departures and subsequent collisions. 3. Blind Spot Detection (BSD) - BSD systems use sensors or cameras to monitor a vehicle's blind spots, or areas that are not visible to the driver. If the system detects a vehicle in the driver's blind spot, it can provide an alert to the driver, helping to prevent collisions during lane changes or other maneuvers.

answer:1. Planning: In this stage, the software development team identifies the project requirements and objectives, creates a roadmap for development, and estimates the budget and time required for the project. A detailed project plan is created, and the stakeholders are informed about the project timeline and the milestones. 2. Analysis: In this stage, the software development team analyzes the requirements of the project by gathering information from stakeholders, users, customers, and other relevant sources. The team identifies the functional and non-functional requirements of the software and creates a detailed functional specification document. 3. Design: In this stage, the software development team designs the software architecture and creates a high-level design document. This includes the selection of programming languages, frameworks, and technologies, as well as the user interface design, database design, and other technical specifications. 4. Development: In this stage, the software development team starts writing the code for the software as per the design document. The development process involves building, testing, and integrating the software components until the working software is ready. 5. Testing: In this stage, the software development team conducts various tests on the software to ensure that it meets the specified requirements and works as per the design. These tests include unit testing, integration testing, system testing, and acceptance testing. 6. Deployment: In this stage, the software is deployed on the production server, and the software is tested in a live environment. This involves making the software available to end-users and ensuring that it works smoothly without any glitches. 7. Maintenance: In this stage, the software development team provides ongoing support and maintenance to the software by fixing any bugs, updating software patches, and enhancing its features based on feedback from users.

answer:To modify the code to address more complex printing issues, such as uneven printing or paper jams, you can add additional conditions to the existing code or create new functions to handle these issues. Here are some steps you can take: 1. For uneven printing, you can add a condition to check if the printer head is dirty or clogged. If so, you can suggest cleaning the printer head or using a cleaning kit. 2. For paper jams, you can create a new function to handle this issue. The function can check if there is any paper stuck in the printer and provide instructions on how to remove the paper. You can also suggest checking for any torn pieces of paper or debris that may be causing the jam. Here's an example of how the code can be modified to address these issues: ``` def print_issues(ink_level, paper_supply): if ink_level <= 0: print("The problem may be caused by low ink levels. Please replace the ink cartridge.") elif paper_supply <= 0: print("The problem may be caused by an empty paper tray. Please refill the tray.") else: print("The printer is functioning properly.") # Check for uneven printing if uneven_printing(): print("The problem may be caused by a dirty or clogged printer head. Please clean the printer head or use a cleaning kit.") # Check for paper jams if paper_jam(): print("The problem may be caused by a paper jam. Please remove any stuck paper and check for torn pieces of paper or debris.") def uneven_printing(): # Code to check if printer head is dirty or clogged # Return True if printer head is dirty or clogged, False otherwise pass def paper_jam(): # Code to check if there is a paper jam # Return True if there is a paper jam, False otherwise pass ``` By adding these additional conditions and functions, the code can now handle more complex printing issues and provide more specific instructions on how to address them.

answer:To search for a specific word or phrase within a file or directory using the `grep` command, you can use the following syntax: ``` grep "word or phrase" /path/to/file ``` For example, to search for the word "fox" within a file containing the sentence "The quick brown fox jumps over the lazy dog", you can use the following command: ``` grep "fox" /path/to/file ``` This will output the entire line containing the word "fox". To replace a specific word or phrase within a file using the `sed` command, you can use the following syntax: ``` sed 's/old-word-or-phrase/new-word-or-phrase/g' /path/to/file ``` For example, to replace the word "fox" with "cat" within a file containing the sentence "The quick brown fox jumps over the lazy dog", you can use the following command: ``` sed 's/fox/cat/g' /path/to/file ``` This will replace all occurrences of the word "fox" with "cat" within the file.
