Flexible electrically conductive nanowires are now a key component in the fields of flexible devices. The achievement of metal nanowire with good flexibility, conductivity, compact and smooth morphology is recognized as one critical milestone for the flexible devices. In this study, a two-beam laser direct writing system is designed to fabricate AgNW on PET sheet. The minimum width of the AgNW ...

This ?aper deals with a robotic system in which the end-point is directly controlled. It consists of a remote guidance subsystem and a manipulator with an end-of-arm sensor subsystem. The guisance subsystem transmits and manipulates a laser beam in space, and the sensor detects the beam, sends the information to the robot controller, which, in turn, instructs the manipulator to follow the beam....

In the present design of the TESLA Linear Collider with integrated X-ray Laser Facility it is necessary that 1 ms long bunch trains with about 10000 bunches are generated and distributed to several free electron laser (FEL) beam lines. The different scientific applications of the X-ray FELs need specific filling patterns of the bunches in the bunch train. It is shown that a fast switch-yard bas...

The problem of transient dynamics of highly flexible three-dimensional space-curved beams, undergoing large rotations and stretches, is treated. The case of conservative force loading, which may also lead to configuration-dependent moments on the beam, is considered. Using the three parameters associated with a conformal rotation vector representation of finite rotations, a well-defined Hamilto...

We propose a low-resolution analog-to-digital converter (ADC) module assisted hybrid beamforming architecture for millimeter-wave (mmWave) communications. We prove that the proposed low-cost and flexible architecture can reduce the beam training time and complexity dramatically without degradation in the data transmission performance. In addition, we design a fast beam training method which is ...

The paper presents a practical robust controller design methodology based on recent theoretical results on minimax LQG control. This controller design methodology is illustrated with the design of a robust feedback controller for the control of vibrations in a flexible cantilever beam. The minimax LQG control approach is used to design a controller which minimizes the total vibration energy in ...

The paper presents a continuous speech recognition system which integrates an additional acoustic knowledge source into the data-driven beam search algorithm. Details of the object oriented implementation of the beam search algorithm will be given. Integration of additional knowledge sources is treated within the flexible framework of Dempster-Shafer theory. As a first example, a rule-based plo...

We demonstrate experimentally that the energy from a highly localized free-electron-beam excitation can be converted via a planar plasmonic metamaterial to a low-divergence free-space light beam. This emission, which emanates from a collectively oscillating coupled metamolecule nanoantenna ensemble much larger in size than the initial excitation, is distinctly different from cathodoluminescence...

the aim of the present paper is to evaluate the influence of the soil- foundation- structure interaction (sfsi) effects on the component demand modifier factor of concrete gravity beams based on asce 41-06 standard. to this end, the beam on the nonlinear winkler foundation approach is employed which is a simple and efficient method. at first, four sets of 3-, 6-, 10- and 15-storey concrete mome...
