In this paper, we seek to model natural human-robot interactions in human-robot teams that support adjustable autonomy and interactions. We present a theoretical characterization of interaction efficiency. We then perform case studies to validate this theoretical framework. Specifically, in one case study we compare interaction efficiency between a shared control teleoperation algorithm and tra...

A simulation method is employed to value Adustable Rate Mortgages, (ARMS). It is used to price two typical instruments: an ARM linked to a Treasury interest rate and an ARM linked to a "Cost of Funds" Index. Contractual provisions such as the margin over the index, caps and floors on the ARM's rate or on the monthly prepayment, reset frequency, and the "teaser" rate are examined for their influ...

In this paper, a novel stator current based Model Reference Adaptive System (MRAS) estimator for speed estimation in the speed-sensorless vector controlled induction motor drives is presented. In the proposed MRAS estimator, measured stator current of the induction motor is considered as a reference model. The estimated stator current is produced in an adjustable model to compare with the measu...

Fiberglass is a material that used for several products. This was chosen because it has many advantages compared to other materials, namely better resistance, relatively affordable production costs and easy shape. PT.X one of the manufacturing companies engaged in fiberglass, manufacture pipes body from vehicles. In this case study company still uses hand milling manual processing. pipe molded ...

This paper describes a hybrid simulation environment, interfaced to an adjustable autonomous software architecture, for validation and evaluation of advanced designs using dynamic interactive scenarios. The simulator provides support for "real-time" evaluation of adjustable autonomy strategies. In such evaluations, control actions by the operator interact with hardware events, including device ...

-Power quality behavior on connecting single phase fed adjustable speed drives to a grid which photovoltaic as the power generation is studied in this paper. A MATLAB/Simulink simulations are performed to investigate the existence of power quality parameter and the system problems that may be resulted from operation of this type of load. The results indicate a potential serious power quality pr...

An optical cell is described for high-throughput backscattering Raman spectroscopic measurements of hydrogen storage materials at pressures up to 10 MPa and temperatures up to 823 K. High throughput is obtained by employing a 60 mm diameter × 9 mm thick sapphire window, with a corresponding 50 mm diameter unobstructed optical aperture. To reproducibly seal this relatively large window to the ce...

This study examines the performance of a new adsorbent, hexagonal nanostructured zeolite particles (HNZP) for acetone adsorption and compares the results with that of commercial mobil synthetic zeolite-5 (ZSM-5) type zeolite. The HNZP is a pure siliceous adsorbent with different values of pore diameter and surface area being adjustable by the manufacturing condition. The results indicate that a...
