A band pass filter with tilted ladder shaped patch and U-shaped geometries is proposed in this paper. Feed are connected at the end of open ended stubs. Presented filter is suitable for the application of wireless application in L-band range. A flat passband response can be achieved when it is employed to implement a bandpass filter. The resonator also exhibits attenuation poles close to the ed...

We propose that the mushroom-shaped structure of the Galactic worm GW 123.4–1.5 is created by a cloud collision with the Galactic gas disk. A hydrodynamic simulation shows that a mushroom-shaped structure is created after the cloud crosses the Galactic midplane. The lifetime of the mushroom-shaped structure is of order the dynamical time scale of the disk, ∼ 10 years. We find that the velocitie...

PCFs (Photonic Crystal Fibers) with ‘T’ – shaped core have been proposed in this paper. –shaped PCF structures analyzed using two different background materials: silica and lead silicate. A total of 3600 rotation at an interval 900 has introduced the design structures. A, B, C D 00, 900, 1800 2700 as wafer. Similarly E, F, G H similar silicate material. Numerical investigations shows ‘D’, ‘F’, ...

There is increasing interest in using cross-laminated timber (CLT) buildings because of its high strength and stiffness. In Japan, structural design guidelines for CLT were established 2016 construction mid-rise increasing. Wide-panel walls can exceed widths 10 m integrate cut-outs window door openings. However, under lateral loads, corner cracks at the openings have been most prevalent failure...

Abstract The effect of aspect ratio and baffle shape on natural convection patterns in a U-shaped cavity filled with CuO water-based nanofluid is examined detail, T-shaped attached to the cold wall. To solve coupled continuity, momentum, energy equations, finite volume method used, pressure–velocity coupling iteratively solved SIMPLE algorithm. study investigates impact Rayleigh number (10 4 –1...

Abstract The T-Shaped designer has previously been identified as a design engineer with the desirable set of skills for successful career. Twelve engineers ranging from novice to expert, were interviewed gain an understanding their skill set, how it evolved and needs evolve in order be futureproofed. With use qualitative, quantitative data development novel engineering profiling method, this pa...
