A file timestamp might not show the time at which a crime was committed for several reasons:

1. A file timestamp typically shows the time of the file's creation, modification, or access, but not the exact time when a crime took place. The crime could have occurred earlier or later than the timestamp.

2. The timestamp on the file could have been altered or manipulated intentionally by the person committing the crime to hide evidence or create confusion about the timeline of events.

3. The device or system where the file is stored may have incorrect or unsynchronized time settings, leading to inaccurate timestamps.

4. There might be a delay between the crime being committed and the file being created or modified, meaning the timestamp would reflect the later time rather than the actual time of the crime.

In summary, a file timestamp might not show the time at which a crime was committed due to factors such as the nature of timestamps, intentional manipulation, system errors, or delays in file creation or modification.

Answer: Therefore, the annual depreciation for each year using the double-declining-balance method is $228,000 for the first three years, $194,000 for the fourth year, and $0 for the fifth year. The book value at the end of each year is as follows: $422,000 at the end of year 1, $194,000 at the end of year 2, $228,000 at the end of year 3, $0 at the end of year 4, and $80,000 at the end of year 5.

Explanation:  To calculate the annual depreciation using the double-declining-balance method, we first need to calculate the depreciation rate, which is double the straight-line depreciation rate. The straight-line depreciation rate is calculated as follows:

Depreciation rate = (Cost - Salvage value) / Useful life

Depreciation rate = ($650,000 - $80,000) / 5 years = $114,000 per year

Double-declining-balance depreciation rate = 2 x straight-line depreciation rate = 2 x $114,000 = $228,000 per year

Using this depreciation rate, we can calculate the annual depreciation and book value at the end of each year as follows:

Year 1:

Depreciation = $228,000

Book value = Cost - Depreciation = $650,000 - $228,000 = $422,000

Year 2:

Depreciation = $228,000

Book value = Cost - Depreciation = $650,000 - $228,000 - $228,000 = $194,000

Year 3:

Depreciation = $194,000

Book value = Cost - Depreciation = $650,000 - $228,000 - $194,000 = $228,000

Year 4:

Depreciation = $228,000

Book value = Cost - Depreciation = $650,000 - $228,000 - $194,000 - $228,000 = $0

Year 5:

Depreciation = $0

Book value = Salvage value = $80,000

Security groups and role-based permissions management are both methods for controlling access to resources in a system, but they differ in their approach.

Security groups are a collection of users or entities that have the same level of access to a resource. They are typically created based on job function or department, and can be used to grant or revoke access to resources as needed. For example, a security group might be created for all employees in the finance department, and they would have access to specific financial systems and data.

Role-based permissions management, on the other hand, is a more granular approach to access control that assigns specific permissions to individual users based on their role or job function. This means that each user can have a unique set of permissions based on their specific needs. For example, a manager might have access to view and approve reports, while a regular employee might only have access to view their own reports.

In summary, security groups provide a broad level of access control based on job function or department, while role-based permissions management provides a more specific and individualized approach to access control based on user roles or job functions.

Stair pressurization is an important safety feature in hi-rise buildings. The purpose of this system is to maintain a higher air pressure inside the stairwells than the air pressure outside. This creates a pressure barrier that prevents smoke and other harmful gases from entering the stairwells during a fire or other emergency. This allows occupants to safely evacuate the building using the stairs without being exposed to smoke or other dangerous fumes. Stair pressurization is a critical component of the building's fire safety system and is required by many building codes and regulations.

A stairwell pressurisation system is mechanically designed to establish air pressure variations between adjoining areas – such as an emergency escape route and a burning room.
