Increase of the saturation power may be approached by means of the parameter adjustment even in a uniform wiggler configuration, which is comparable to the enhancement by using a tapered wiggler. Instead of the beam-wave interaction being lengthened by the use of a wiggler taper, a substantial saturation length may be shortened by virtue of the parameter adjustment.
A kind of auxiliary device for ankle rehabilitation based on ball pin vice is designed and developed. The device has two degrees of freedom, but it can achieve approximatively the three-dimensional movement of the bionic ankle. When the device is used for auxiliary ankle rehabilitation, which only leads ankle to rotate not to move, and its structure is very simple. The ball pin pairs are adopted as...
In this paper, we present a novel approach for the intrinsic mapping of anatomical surfaces and its application in brain mapping research. Using the Laplace-Beltrami eigen-system, we represent each surface with an isometry invariant embedding in a high dimensional space. The key idea in our system is that we realize surface deformation in the embedding space via the iterative optimization of a conformal...
A free space miniature optical spectrometer is demonstrated by utilizing a hole array as the dispersive component. Tikhonov regularization method is used to make the reconstructed spectrum similar to the original one.
As research upon systematic risk around national public project in China is emerging, a contextualized model incorporating cognitive, social contextual factors as predictors to this risk-aversion and sector response have been relatively limited. The aim of this study was to apply a social-cognitive model of risk perception into concerning on government public project and we build such a structural...
The quantum Langevin analysis for QCLs show that coupling strength and dephasing rate strongly affect the linewidth of THz QCLs in incoherent resonant-tunneling transport regime, but induce insignificant influence for mid-infrared QCLs due to strong coupling.
This paper presents the design of a database system for a clothing store using PHP code and MySQL database that performs search functions for selected products. There will be a concentration on the administrator and employee login where they can access specific items in their inventory, and check who signed up for different opportunity the store offers. The system will also give customers a chance...
This paper presents a research on remote access which will show how a personal cell phone and a personal computer communicate over the Internet in order to access the hard drive as well as the desktop by the phone. There is a focus on completing several tasks on the computer from the phone such as uploading and downloading files. There is a wide range of tasks that can be completed through the phone...
We report a 9.1 GHz fiber-based RF frequency dissemination chain over 80 km. Using an improved phase noise compensation scheme, the frequency dissemination stability has been improved from 4×10−17/105 s to 1.1×10−18/105 s.
In this paper we discuss the use of wind power forecasting in electricity market operations. In particular, we demonstrate how probabilistic forecasts can contribute to address the uncertainty and variability in wind power. We focus on efficient use of forecasts in the unit commitment problem and discuss potential implications for electricity market operations.
The aim was to further validate the electrocardiographic imaging method we introduced previously — involving inverse calculation of heart-surface potential distributions from the 12-lead ECG — by comparison with data provided by single photon emission computed tomography (SPECT). To perform the electrocardiographic inverse solution, we used a torso model with 352 body-surface and 202 heart-surface...
