The forecast of typhoon tracks remains uncertain and is positively related to the accuracy storm surge forecast. prediction error increases dramatically when track larger than 100 km. This study aims develop an ensemble system using parametric weather models account for uncertainty in prediction. model adopted this COMCOT-SS system. Two methods are introduced analyzed generate members study. On...

This paper analyzes fluid scale asymptotics of two models generalized Jackson networks employing the earliest deadline first (EDF) policy. One applies ‘soft’ EDF policy, where deadlines are used to determine priority but jobs do not renege, and other implements ‘hard’ EDF, renege when expire, postponed with each migration a new station. The arrival rates, distribution service capacity allowed f...

Packet networks are currently enabling the integration of traffic with a wide range of characteristics that extend from video traffic with stringent QoS requirements to the best-effort traffic requiring no guarantees. QoS guarantees can be provided in conventional packet networks by the use of proper packet scheduling algorithms. As a computer revolution, many scheduling algorithms have been pr...

The medial axis is an important shape descriptor first introduced by Blum [2] via a grassfire burning analogy. However, the medial axes are sensitive to boundary perturbations, which calls for global shape measures to identify meaningful parts of a medial axis. On the other hand, a more compact shape representation than the medial axis, such as a “center point”, is needed in various application...

Packet networks are currently enabling the integration of heterogeneous traffic with a wide range of characteristics that extend from video traffic with stringent QoS requirements to best-effort traffic requiring no guarantees. QoS guarantees can be provided in packet networks by the use of proper packet scheduling algorithms. In this paper, we propose a new priority assignment scheduling algor...

Modern embedded systems are often required to execute under stringent real-time constraints to satisfy high performance requirements. When the available computational resources are scarce, an efficient implementation of the scheduler is of crucial importance for containing system costs. In this paper, we present an efficient implementation of the Earliest Deadline First (EDF) scheduler, which i...

OBJECTIVE Traditional electroencephalogram (EEG) recorders reject low frequencies and DC and therefore cannot handle fullband EEG. Dedicated fullband recorders use non-standard file formats, because the standard format (EDF) cannot handle large DC electrode offset voltages. Both facts limit the development and use of fullband EEG. We developed a modification that allows conventional equipment t...

BACKGROUND Fluoresence microscopy is an extremely useful tool to analyze the intensity, location and movement of fluorescently tagged molecules on, within or between cells. However, the technique suffers from slow image acquisition rates and limited depth of field. Confocal microscopy addresses the depth of field issue via "optical sectioning and reconstruction", but only by further reducing th...
