background: various studies are seeking to find new methods to improve techniques of laryngeal mask airway (lma) insertion and reduce possible complications. in this study, we embarked on a clinical study to investigate the advantages of a new insertion method of laryngeal mask and to compare it with the classic method. materials and methods: two hundred patients aged 20-60 years old in 2012 we...

We consider the problem of evaluating an appointment schedule for outpatients in a hospital. Given a fixed-length session during which a physician sees K patients, each patient has to be given an appointment time during this session in advance. When a patient arrives on its appointment, the consultations of the previous patients are either already finished or are still going on, which respectiv...

Various activities that intend to enhance performance, reliability, and availability of systems are scheduled with low priority and served during system idle times. Under such conditions, idleness becomes a valuable “resource” that needs to be efficiently managed. A common approach in system design is to be non-work-conserving by “idle waiting”, i.e., delay scheduling of background jobs to avoi...

A scheduling technique is presented to minimize service delay of aperiodic tasks in hard real-time systems that employ dynamic-priority scheduling and do not allow task preemption. In a real-time scheduling process, the execution of periodic tasks can be deferred as long as this does not cause other tasks to violate their time constraints. However, aperiodic tasks that usually have urgent missi...

In this paper we present a brokerage system for making idle cpu ressources of anonymous users of the World Wide Web accessble for distributed Web-Computing. The Locust (LOw cost Computing Utilizing Skimmed idle Time) Broker collects and remarkets the aggregated ressources by means of ubiquitious Web and Java technologies and creates an electronic spot market focused on the mainstream Internet u...

although several papers have studied no-idle scheduling problems, they all focus on flow shops, assuming one processor at each working stage. but, companies commonly extend to hybrid flow shops by duplicating machines in parallel in stages. this paper considers the problem of scheduling no-idle hybrid flow shops. a mixed integer linear programming model is first developed to mathematically form...

Mobile Ad hoc Network (MANET) is a self-organized network where network is set up on the fly. Some of the issues in MANETs are routing, security, power management, bandwidth management, mobility management, etc. Correct estimation of the available bandwidth is one of the essential components for efficient network resource management and seamless mobile service provisioning of Quality of Service...
