We describe a method for bridging internet time delays in a teleoperation scenario where the the time delays are large compared to the task execution time. The method proposed uses minimum jerk motion models to predict the input from the user a time into the future that is equivalent to the communication delay. We present results from a teleoperated ball catching experiment, where we show that ...

The input output automaton model has recently been de ned in LT LT as a tool for modeling concurrent and distributed discrete event systems of the sorts arising in computer science Since its introduction the model has been used for describing and reasoning about several di erent types of systems including network resource allocation algorithms communication algorithms concurrent database system...

A two-station network with controllable inputs and sequencing control, proposed by Wein [23], is analyzed. A control is sought to minimize holding cost subject to a throughput constraint. In a Lagrangian formulation, input vanishes in the fluid limit. Several alternative fluid models, including workload formulations, are analyzed to develop a heuristic policy for the stochastic network. Both th...

We develop a scale-dependent nonlinear input-output model which is a practical alternative to the conventional linear counterpart. The model contemplates the possibility of different assumptions on returns-to-scale and is calibrated in a simple manner that closely resembles the usual technical coefficient calibration procedure. Multiplier calculations under this nonlinear version offer interval...

An Analysis of the Total Insensitivity of Input Shaping Designs Lucy Y. Pao Electrical and Computer Engineering Department University of Colorado Boulder, Colorado 80309{0425 Abstract In the modeling of exible structures, there is generally uncertainty in both the frequencies and damping constants, and it is thus important that the control methods for such systems be robust to these uncertainti...

This paper presents some thoughts on problems arising in I/O systems. Firstly, the I/O needs of processors and multiprocessors and currently-used solutions are outlined. Next, for a multiprocessor architecture with Uniform Memory Access (UMA) a set of RAID-type disks is proposed whose access model is called Uniform Disk Access (UDA). A multiport disk cache with ultra-high-rate serial links carr...

Numbers of the programs are poorly written, lacking even the most basic security procedures for handling input data from users. The input validation vulnerability can be detected by many tools but few tools can fix the flaws automatically. The security gateway can used to protect vulnerable Web sites immediately but it may induce false recognition through impersonal rule. By means of hybrid ana...

Multiple Pointing Input System(MPIS) allows concurrent manipulation of multiple pointing devices, and is targeted as a generic input system. This paper reports on an experimental evaluation on our MPIS prototype system. The system allows concurrent manipulation of multiple pointing devices. The experiment has subjects sort 8 objects on the screen in displayed order. We found that concurrent man...

Multimodal dialogue systems allow users to input information in multiple modalities. These systems can handle simultaneous or sequential composite multimodal input. Different coordination schemes require such systems to capture, collect and integrate user input in different modalities, and then respond to a joint interpretation. We performed a study to understand the variability of input in mul...

Introduction: Automatic arterial input function (AIF) selection has an essential role in quantification of cerebral perfusion parameters. The purpose of this study is to develop an optimal automatic method for AIF determination in dynamic susceptibility contrast magnetic resonance imaging (DSC-MRI) of glioma brain tumors by using a new preprocessing method.Material and Methods: For this study, ...
