A computerized system for appointment scheduling, medical record keeping, medical billing, patient tracking, and epidemiologic data generation was developed and applied in an indigent pediatric otologic clinic. Functions used to augment appointment compliance are 1) notifying the referring physicians, agencies, and health department coordinators of failed appointments and sending medical inform...

Process migration is an useful mechanism to offer load balancing. In this context, we developed a model called MigBSP that controls processes rescheduling on BSP applications. MigBSP is especially pertinent to obtain performance on this type of applications, since they are composed by supersteps which always wait for the slowest process. In this paper, we focus on the BSP-based modeling of the ...

Disturbing effects of aircraft noise depend on the time of day at which the sound sources emerge. The reason can be seen in different human activities which vary qualitatively throughout the day. Especially in the evening and during the night people are more sensitive against noise induced disturbances which is a result of several field studies. Additionally there exists empirical evidence that...

Real world systems can be thought of as structures of activities that require resources in order to execute. Costs are reduced when resource levels are kept low, but this can lead to competition for resources that can cause poor system performance. Careful allocation of resources can improve system performance by enabling more efficient use of resources. This paper proposes that resource schedu...

This paper proposes the rescheduling of the SHA-1 hash function operations on hardware implementations. The proposal is mapped on the Xilinx Virtex II Pro technology. The proposed rescheduling allows for a manipulation of the critical path in the SHA-1 function computation, facilitating the implementation of a more parallelized structure without an increase on the required hardware resources. T...

The relationship between the (open-loop) optimization problem that is repeatedly solved online and the quality of the (closed-loop) schedule that is implemented, is poorly understood, even in the deterministic case. We investigate various attributes of the open-loop problem and the rescheduling algorithm that affect the quality of closed-loop schedules, viz. rescheduling frequency, scheduling h...

Abstract This paper presents a solution for the transmission congestion management considering voltage stability issues using optimal generation rescheduling. While practicing optimization techniques, control variables remain under their upper or lower limits but it may lead to lowered level of security after optimization. To counterbalance this adverse effect, modified objective function has b...
