This work describes the study of coil for Magnetic Resonance Imaging (MRI) application. Concretely, the principal objective is the design of a birdcage coil (RF coil) to use in a 7 Tesla scanner. More strength field has a better SNR and increased chemical shift effects, improving spectral fat suppression and spectroscopy. Moreover, a better SNR increases the spatial resolution or reduces the im...

A new type of rotating anticathode X-ray generator, where an electron beam of up to 60 keV irradiates the inner surface of a U-shaped Cu anticathode, has achieved a beam brilliance of 130 kW mm(-2) (at 2.3 kW). A higher-flux electron beam is expected from simulation by optimizing the geometry of a combined-function-type magnet instead of the fringing field of the bending magnet. In order to min...

This paper presents a simple structure and small size antenna design with dimensions of 43×47 mm 2 to perform an ultra-wideband (UWB) frequency range using semicircular co-planar waveguide (CPW). has been designed simulated by the computer simulation technology (CST) microwave studio suit. In this work, we (about GHz 10 GHz) feeding semi-circular compact via for input impedance 50 Ω. The CST re...

Abstract In this work, the analysis of patch antenna design at resonant frequency 2.4 GHz and 3.5 are presented. Both proposed antennas made RT Duroid 5880 designed simulated using CST Studio Suite software. The designed, their performances examined. have been based on size improvement technique to improve fabrication tolerance. characteristics both antennas’ including return loss, radiation pa...

Personalized teaching and classified training promote each student to develop in the most suitable direction. The studies on (CST) mainly target objects of CST, which refers underachievers achievers, or different groups high-quality talents like doctoral students master candidates. However, there are few research results implementation quality forecast CST. To fill up gap, this paper explores p...

Strong continuous and discontinuous shear thickening (CST DST) have been shown to be rationalized by the formation of a network frictional contacts. This continuously evolving is investigated here using k-core analysis configurations obtained based on discrete-particle simulation method. The approach identifies clusters in which each particle has at least k contacts with other particles same cl...

In this study, a new terahertz cross-shaped metamaterial bandpass filter is designed, simulated and fabricated. Among the properties of proposed filter, compared to built-in filters (especially filters), one may refer higher output transfer intensity (of almost 100%) less noise effects (unwanted frequencies) in whole range 0.1 3 THz. The simulation conducted by CST STUDIO software FDTD method. ...

Let A be an array of n elements taken from a totally ordered set. We present a data structure of size 3n+ o(n) bits that allows us to answer the following queries on A in constant time, without accessing A: (1) given indices i < j, find the position of the minimum in A[i..j], (2) given index i, find the first index to the left of i where A is strictly smaller than at i, and (3) same as (2), but...

Initially, a design study is presented for a W-band planar coupled-cavity backward wave oscillator at 94.5 GHz. It is numerically simulated using CST particle-in-cell (PIC)-3D simulator and same design validated with another PIC-3D code. Further, output powers of several BWOs combines in a typical manner which resulted power multiplication order of 2.5 times and electronic efficiency multiplica...

In this paper, computational fluid dynamics (CFD) is utilized to characterize a prototype biolistic delivery system, the biomedical device based on the contoured-shock-tube design (CST), with the aim at investigating shocks induced flow instabilities within the contoured shock tube. The shock/interface interactions, the growth of perturbation at an interface between two fluids of different dens...
