the database detects two deadlocked transactions. to break the deadlock, the database rolls back one of the transactions.
Answers
The best technique for detecting deadlocks is this one. Based on the transaction and their lock, this approach builds a graph. There is a deadlock if the generated graph contains a cycle or closed loop.
How do you detect deadlocks in a database?A deadlock occurs when two or more transactions are waiting endlessly for one another to release locks. One of the most dreaded issues with DBMS is deadlock, which prevents tasks from ever being completed and keeps them in the waiting state indefinitely.As an illustration, Transaction T1 has to update some rows in the grade table while holding a lock on some rows in the student table. While Transaction T1 is updating the rows of the Student table that are locked by Transaction T2, Transaction T2 is simultaneously holding locks on some rows in the Grade table.The primary issue now appears. Currently, transaction T1 is waiting for transaction T2 to release its lock, and vice versa. All activities stop and remain at a standstill. Until the DBMS recognizes the stalemate and terminates one of the transactions, it will stay in a standstill.To Learn more About deadlocks refer to:

to implement a new user based authentication solution
This solution includes granting logical access based a
physical location and proximity. Which of the following
the BEST autentication solution for George to implement
Answers
Answer:
Explanation:
There are several options for implementing user-based authentication based on physical location and proximity. One option could be to use a combination of two-factor authentication (2FA) and location-based authentication.
Two-factor authentication involves requiring users to provide two different forms of authentication in order to access a system. This could include something the user knows (e.g. a password), something the user has (e.g. a security token), and/or something the user is (e.g. a fingerprint). By requiring two forms of authentication, it increases the security of the system and makes it harder for unauthorized individuals to gain access.
Location-based authentication involves using the user's physical location as an additional factor in the authentication process. This could be done using GPS coordinates or by detecting the user's proximity to a specific location or device (e.g. using Bluetooth). By requiring users to be in a specific location in order to access the system, it adds an additional layer of security.
Combining two-factor authentication with location-based authentication can provide a strong solution for user-based authentication. However, it is important to carefully consider the specific requirements and constraints of the system and ensure that the chosen solution is appropriate and effective.

dog1.CreateLicenseNum(userId);
cout << "Dog license: " << dog1.GetLicenseNum() << endl;
return 0;
}
Answers
Answer:
To define the missing function, you can implement the CreateLicenseNum() function as follows:
void DogLicense::CreateLicenseNum(int customID) {
licenseNum = (100000 * customID) + licenseYear;
}
Once the CreateLicenseNum() function has been defined, the program can be run to generate a license number for a dog using the specified year and custom ID. For example, if the inputs 2014 and 777 are provided, the program would output the following:
Dog license: 77702014
Explanation:
In summary, to define the missing function, you can implement the CreateLicenseNum() function as shown above. This function calculates the license number by multiplying the custom ID by 100000 and adding the year of registration to the result. This allows the program to generate a unique license number for each dog based on its custom ID and the year in which it was registered.

For specific identification, the March 9 sale consisted of 60 units from beginning inventory and 190 units from the March 5 purchase; the March 29 sale consisted of 40 units from the March 18 purchase and 80 units from the March 25 purchase.
Answers
FIFO = $108,530 - $85,045 = $23,485
LIFO = $108,530 - $85,430 = $23,100
weighted average = $108,530 - $85,697 = $22,833
specific identification = $108,530 - $85,245 = $23,285
Explanation:
the inventory records are missing, so I looked for a similar question:
first we should calculate COGS:
under FIFO
March 15 sales = (660 x $60) + (55 x $57) = $42,735
September 10 sales = (275 x $57) + (110 x $45) + (160 x $65) + (185 x $61) = $42,310
total = $85,045
under LIFO
March 15 sales = (110 x $45) + (330 x $57) + (275 x $60) = $40,260
September 10 sales = (570 x $61) + (160 x $65) = $45,170
total = $85,430
under weighted average
March 15 sales = 715 x ($108,530 / 1,830) = $42,404
September 10 sales = 730 x ( / 1,830) = $43,293
total = $85,697
under specific identification
(660 x $60) + (230 x $57) + (110 x $45) + (110 x $65) + (335 x $61) = $85,245
What do you mean by FIFO ?First in, first out (FIFO) is an uncomplicated approach of inventory valuation based on the presumption that commodities acquired or created first are sold first. This implies that older inventory is distributed to customers before fresh inventory, in theory. Even if there have been recent changes in expenses, the cost of goods sold (COGS) of the oldest inventory is used to assess the value of ending inventory. More current merchandise often costs more than older stuff due to inflation. Since the lower valued items are sold first when using the FIFO approach, the ending inventory usually has a higher value.

A power cycle operates between hot and cold reservoirs at 600 K and 300 K, respectively. At steady state the cycle develops a power output of 0.45 MW while receiving energy by heat transfer from the hot reservoir at the rate of 1 MW.
(a) Determine the thermal efficiency and the rate at which energy is rejected by heat transfer to the cold reservoir, in MW.
(b) Compare the results of part (a) with those of a reversible power cycle operating between these reservoirs and receiving the same rate of heat transfer from the hot reservoir.
Answers
a) The thermal Efficiency is calculated as; 45%
The rate at which energy is rejected by heat transfer to the cold reservoir, is; 0.55 MW
b) The comparison shows that there is an increased efficiency and reduced heat rejection in the reversible power cycle working between the given two reservoirs
How to determine the thermal efficiency?We are given;
The temperature of the hot reservoir; T_h = 600 K
The temperature of the cold reservoir; T_c = 300 K
The power output; W' = 0.45 MW
The heat input from the hot reservoir; Q'_in = 1 MW
a) The thermal efficiency of the actual cycle is gotten from the formula;
η_actual = W'/Q'_in
Where;
W' is the work done
Q'_in is the heat supplied
Thus;
η_actual = 0.45/1
η_actual = 0.45 = 45%
The rate at which energy is rejected by heat transfer to the cold reservoir, Q_c , is given by the formula;
Q_c = Q'_in - W'
Thus;
Q_c = 1 - 0.45 = 0.55 MW
B) For a reversible power cycle, the maximum cycle efficiency is gotten from the formula;
η_maximum = (T_h - T_c)/(T_h)
Thus;
η_maximum = (600 - 300)/600
η_maximum = 0.5 or 50%
The rate of work done by the cycle is given by the formula;
W' = Q_in - η_maximum
W' = 0.5 MW

The _______________ feature enables smartphones to receive broadcasts from national emergency broadcast systems, such as the Emergency Alert System (EAS) in the United States.
Answers
The emergency notification feature enables smartphones to receive broadcasts from national emergency broadcast systems, such as the Emergency Alert System (EAS) in the United States.
Emergency Alert System (EAS):
The Emergency Warning System (EAS) is a national public warning system commonly used by state and local agencies to communicate critical emergency information, such as weather and AMBER warnings, to affected communities. EAS participants — radio and television stations, cable systems, satellite radio and television providers, and wireline video providers — will voluntarily issue local his alerts, but the president will address the public during a national emergency. must be given the opportunity to do so.
Most EAS alerts are issued by the National Weather Service in response to severe weather, but an increasing number of state, local, territory and tribal agencies are also broadcasting alerts. In addition, the NOAA Weather Radio All Hazards network is the only government-sponsored radio broadcast of warning information to the public and is part of EAS.
It is coordinated jointly by the Federal Emergency Management Agency (FEMA), the Federal Communications Commission (FCC), and the National Oceanic and Atmospheric Administration (NOAA). EAS regulations and standards are administered by the FCC's Public Safety and Homeland Security Bureau. All television, radio, satellite radio stations, and multichannel video program distributors (MVPDs) should participate in this system.
EAS is a front end to the Integrated Public Warning and Warning System (IPAWS) that coordinates the distribution of warning information across multiple channels, including EAS: Wireless Emergency Alerts (WEA) using Common Alerting Protocol (CAP).
