Abstract A research on RCS simulations and analysis of a diamond-shaped thermal jacket was carried out, to make jackets tanks less detectable known radar observation methods. Based the principles stealth technology, modeled. The simulation models were established by employing physical optics method (PO), monostatic characteristics at high frequency region investigated, major components affectin...

Hybrid-wetting surfaces are commonly used in enhancing dropwise condensation (DWC) because of provide high droplet mobility and small size. The shape the patterns plays a significant role determining departure size, frequency, thus, heat transfer rates, which not introduced yet. Therefore, different pattern shapes such as circle, ellipse, diamond share same area, gap distance, arrangement have ...

The field of two-dimensional filters and their design methods has known a large development due to its importance in image processing (Lim, 1990; Lu & Antoniou, 1992). There are methods based on numerical optimization and also analytical methods relying on 1D prototypes. A commonly-used design technique for 2D filters is to start from a specified 1D prototype filter and transform its transfer f...

This paper introduces a new configuration of compact, triangular- and diamond-slotted, microstrip-fed, low-profile antenna for C/X band applications on polytetrafluoroethylene glass microfiber reinforced material substrate. The antenna is composed of a rectangular-shaped patch containing eight triangles and two diamond-shaped slots and an elliptical-slotted ground plane. The rectangular-shaped ...

Dual-scale diamond-shaped gold nanostructures (d-DGNs) with larger scale diamond-shaped gold nanoposts (DGNs) coupled to smaller scale gold nanoparticles have been fabricated via interference lithography as a highly reliable and efficient substrate for surface enhanced Raman scattering (SERS). The inter- and intra-particle plasmonic fields of d-DGNs are varied by changing the periodicity of the...

The current study investigates the two-phase turbulentnanofluid flow insidein a heat exchanger tube equipped with novel type of conical turbulators having two parallel rows holes, for first time.The range Reynolds number was between 4000and20000 under turbulent regime and uniform wall temperature condition.Water is considered as base fluid TiO2 nanoparticles volume fractions of0–2.5% are added ...

Further morphological observations on the particulate components decorating the lumenal surfaces of membranes of the endocytic complex of the epithelial cells of the suckling rat ileum are presented. The particles each measure approximately 7.5 nm across and give the appearance of the capital letter H in frontal view. They consist of the enzyme n-acetyl-beta-glucosaminidase (NAG). They are arra...

A method to investigate light and radiation field congruence utilizing a commercially available amorphous silicon electronic portal imaging device (EPID) was developed. This method employed an EPID, the associated EPI software, and a diamond-shaped template. The template was constructed from a block tray in which Sn/Pb wires, 1 mm in diameter, were embedded into a diamond shaped groove milled i...

In block motion estimation, a search pattern with a different shape or size has a very important impact on search speed and distortion performance. A square-shaped search pattern is commonly adopted in many popular fast algorithms. Recently, a diamond-shaped search pattern was introduced in fast block motion estimation, which has exhibited faster search speed. Based on an in-depth examination o...
