Strategy 1
*Testing for timing, high reliability and performance.
Reasons.
Every device and system configuration must be tested including the software setup,definitions and rules must be tested with an attempt to force the system and its intergrals to fail. Every failure(if there are any) must be evaluated and errors corrected.
Strategy 2
*Measuring response levels at the lowest set point of the alarm.
Reasons.
This is to check the trigger points of the alarms in the system and the response must be recorded as well as changing the intervals of alarm triggers so as to evaluate the time taken for the alarm to respond at the lowest point of it to be triggered.

Since David wants to take pictures of people around him and also the objects far away, a standard lens would be fit for that.

Solution:
The process of transaction can guarantee the reliability of business applications. Locking resources is widely used in distributed transaction management (e.g; two phase commit, 2PC) to keep the system consistent. The locking mechanism, however, potentially results in various deadlocks. In service oriented architecture, the deadlock problem becomes even worse because multiple transactions try to lock shared resources in the unexpectable way due to the more randomicity of transaction requests, which has not been solved by existing research results. In this paper, we investigate how to prevent local deadlocks, caused by the resource competition among multiple sub-transactions of a gl obal transaction, and global deadlocks from the competition among different global transactions. We propose a replication based approach to avoid the local deadlocks, and a timestamp based approach to significantly mitigate the global deadlocks. A general algorithm is designed for both local and global deadlock prevention. The experimental results demonstrate the effectiveness and efficiency of our deadlock prevention approach. Further, it is also proved that our approach provides higher system performance than traditional resource allocation schemes.
This is the required answer.
