2014 A novel chopper-buncher system is under construction for the Rehovot 14UD Pelletron. Beam dynamics calculations of that system are described. The ultimate performance for nickel ions is 100 picoseconds pulse, at a repetition rate of 4 MHz, and transmission of 15 % of the d.c. beam current.

BACKGROUND AND PURPOSE Introduction of an instrument into the working channel of ureteroscopes adversely affects flow and deflection. We evaluated the alterations in ureteroscope channel flow and deflection caused by available Nitinol(R) baskets. MATERIALS AND METHODS We compared the effects of 11 Nitinol baskets on irrigation flow and deflection of three flexible ureteroscopes (Olympus P3, A...

In fully-developed pressure-driven flow, the spreading of a dissolved solute is enhanced in flow direction due to transverse velocity variations phenomenon now commonly referred as Taylor–Aris dispersion. It well understood that characteristics dispersion are sensitive channel’s cross-sectional geometry. Here we demonstrate method for manipulation single rectangular microchannel via controlled ...

Several stiffened plates arrangements subjected to bending were configured applying the Constructal Design Method (CDM) and solved by Finite Element (FEM), aiming through Exhaustive Search (ES) technique analyze influence of transverse I-Shaped or T-Shaped stiffeners in mechanical behavior. Considering a non-stiffened plate as reference maintaining total steel volume constant, portion was deduc...

In this paper, we present a label-based approach for implementing deflection in a photonic packet network, and we introduce an algorithm for determining deflection options in a manner which eliminates looping. A general analytical model is developed to evaluate packet loss probabilities in networks with deflection. The analysis may be applied to a wide class of deflection schemes and may be app...

In this paper, two-dimensional (2D) orthotropic augmented finite element method (A-FEM) is applied to account for progressive failure of composite laminates under transverse loading, which considers all major cracking modes (delamination, fiber kinking/rupture matrix cracking). High-fidelity simulations different stacking loading are implemented. Both predicted load−deflection curves and damage...

Thin-walled workpieces, such as aero-engine blisks and casings, are usually made of hard-to-cut materials. The wall thickness is very small and it is easy to deflect during milling process under dynamic cutting forces, leading to inaccurate workpiece dimensions and poor surface integrity. To understand the workpiece deflection behavior in a machining process, a new real-time nonintrusive method...

A promising option to raising busty interchange in system communication could be Optical Burst Switched (OBS) networks among scalable and support routing effective. The routing schemes with disputation resolution got much interest, because the OBS network is buffer less in character. Because the deflection steering can use limited optical buffering or actually no buffering thus the choice or de...

Atomic force microscopy typically relies on high-resolution high-bandwidth cantilever deflection measurements based control for imaging and estimating sample topography and properties. More precisely, in amplitude-modulation atomic force microscopy (AM-AFM), the control effort that regulates deflection amplitude is used as an estimate of sample topography; similarly, contact-mode AFM uses regul...

abstract the usage of heroin is associated with a variety of neurologic disorders, including acute transverse myelitis. in this study we present a 19 year old man who was suffered from insufflated heroin after several months of abstinence, and admitted to hospital emergency department, unconscious. he responded to fluid therapy and naloxone, but could not move his legs on examination. he had fl...
