In this paper we formulate an analytical performance model to estimate the miss ratio metric commonly used to characterize performance in real-time systems. The model accepts general distributions as inputs.

Abstract We examine firm disclosure choice when information is received on a real-time, continuous basis. use transaction-level credit and debit card sales for sample of retail firms to construct weekly measure abnormal revenue each firm. validate the informativeness this real-time information, confirming its positive correlation with returns, unexpected realizations, management forecast news. ...

Updating real-time system software is often needed in response to errors and added requirements to the software. Stopping a running application, updating the software, and then restarting the application is not suitable for systems with high availability requirements. On the other hand, dynamically updating a system may increase the execution time of the tasks, thus, degrading the performance o...

Real-time database systems are designed to handle workloads where transactions have completion deadlines and the goal is to meet these deadlines. However, many real-time database environments are characterized by workloads that are a & of real-time and standard (non-real-time) transactions. Unfortunately, the system policies used to meet the performance goals of real-time transactions often wor...
