Cloud computing is one of the concept in virtual technology. Virtualization means that is not real but its provides the all facilities to all different users. Virtualization provides efficient solution in different number of real time applications. Cloud computing is ready to provide the services efficiently to all users. Different numbers of users are submitting the different jobs. All jobs ar...

Spatial databases are entering an era of mass deployment in various real-life applications, especially mobile and location-based services. The real-time processing of spatial queries to meet different performance goals poses new problems to the real-time and parallel processing communities. In this paper, we investigate how multiple window queries can be parallelized, decomposed, scheduled and ...

Real-time operating systems generally depend on some form of priority information for making scheduling decisions. Priorities may take the form of small integers or deadline times, for example, and the priorities indicate the preferred order for execution of the jobs. Unfortunately, most systems suffer from some degree of priority inversion where a high priority job must wait for a lower priori...

The real time data is stored in real time database. To maintain the temporal validity of real time data different real time scheduling algorithms are used. The valid data is further used for different operations in real time sensing and control system or in process control applications. The real time data values are stored in real time database at every instant of time. So previous data value b...

 An adaptive input-output linearization method for general nonlinear systems is developed without using states of the system. Another key feature of this structure is the fact that, it does not need model of the system. In this scheme, neurolinearizer has few weights, so it is practical in adaptive situations.  Online training of neuroline...

by Shengyan Hong A Cyber-Physical System (CPS) is a system where physical components and computational components are tightly integrated. Tasks in a CPS generally need to be accomplished correctly in terms of not only functionality but also punctuality. Real-time scheduling provides the methodology of determining the task execution order on a shared resource in order to make as many tasks in a ...

Scheduling in Real-time systems differs from scheduling in conventional models in two principal ways: (a) Parameter variability, (b) Existence of complex constraints between jobs. Our focus has been on variable execution times. Whereas traditional models assume fixed values for job execution time, we model execution times of jobs through convex sets. The second feature unique to real-time syste...

Mixed-criticality (MC) systems [1] allow tasks of different importance (or criticality) to be consolidated into a single system. Consolidation facilitates resource sharing (even across criticality levels) and hence bears the potential to reduce the overall amount of resources needed. However, there is a common misconception that recurs in literature about Vestal’s model: the false believe that ...
