These jobs are often with the property of deadline constraint and have to be completed within limited time. Therefore, to schedule a job with workflow (short for workflow) with deadline constraint is increasingly becoming a crucial research issue. In this paper, we, based on previous work, propose an agent-based workflow scheduling mechanism to schedule workflows that are with deadline constraint into federated cloud environment. Design and Methods: We add a workflow agent into the original framework to schedule the deadline-constraint workflow. The workflow agent can smoothly schedule workflows to the cloud system according to their required resource and automatically monitor their execution. In order to accurately predict the execution time of each task to meet deadline constraint on certain VM with given resource, we inherit the use of rough set theory to estimate execution time of task in our previous work. Result and Discussion: A heuristic algorithm that is embedded into the workflow agent is also proposed because the problem had been shown to be NP-complete. The mechanism also adopts dynamic job dispatching method to reduce the usage of VM and to improve the resource utilization. We also conducted experiments to evaluate the efficiency and effectiveness. The experimental results show that the prediction time is very close to the real execution time and can efficiently schedule multiple scientific workflows to meet the deadline constraints simultaneously. KEYWORDS cloud computing, deadline constraint, hybrid cloud, mobile agent, workflow scheduling With the rapid development of cloud computing, 1-3 a variety of applications have been partially or fully migrated from traditional computing environment to cloud. Cloud computing environment can be classified as follows 8 : public cloud, private cloud, community cloud, and hybrid cloud, in which the hybrid cloud merges both advantages of public and private cloud to integrate them together for providing various services with maximizing the utilization of private cloud and minimizing the cost of public cloud. 9 In addition, while the jobs with deadline constraint submitted to cloud environment, public cloud, based on pay-as-you-go charging model, can serve as resource pool handling dynamical and urgent requests. Therefore, exploiting hybrid cloud, the organizations

The simultaneous development of these two diseases accelerates the progression of dementia, leading to a reduction in the patient's quality of life. This is difficult for caregivers, as it causes them to shoulder a greater burden and brings greater emotional stress, resulting in their wanting to end the care relationship or even neglect or abuse patients. In addition, their own mental and physical health is also severely affected, causing them to seek medical treatment themselves. In view of this problem, we propose a cloud-based physiological sound-controlled intelligent music and blood-pressure control system to assist family caregivers of dementia patients to reduce their burden as well as their stress. We interview family caregivers regarding the benefits of this system in assisting them and find that most caregivers find the system to be helpful.

Globus Toolkit is one of the most important tools in the industry to construct grid environment. The newest version of Globus Toolkit (GT4) adopts Services Oriented Architecture (SOA) to provide grid environment based on Web Services. However, Globus Toolkit does not guarantee to reliably send and receive messages during messages passing between Web Services. Once systems crash or network fails during messages communication, it will cause the messages to be lost. For enterprise, this will make very serious effect. Furthermore, the messages communication mechanism which Globus Toolkit Java Web Services core provides is based on the changes of resource properties. In other words, it regards messages as resources properties but that is unreasonable for the perspectives of the programmers. With the rapidly growth of Internet, Message Oriented Middleware (MOM) has become the widespread used tool for delivering messages between enterprises. Sun Corporation has defined the Java Message Service Application Programming Interface (JMS API) to provide a unified interface for portability of the programs v Table of Contents Chinese Abstract ....
Implementing a Workflow Agent on Federated Cloud

In a cloud platform, the resources can be utilized more effectively and efficiently by scheduling the workflow properly. In this paper, an agent-based workflow scheduling mechanism on cloud environment is proposed. We implement a set of agents that can federate multiple clouds and automatically monitor the entire system, and manage the job if it's a workflow job. We also implement a dynamic job dispatching algorithm to reduce the VM usage amount and improve the resource utilization.
