This paper deals with flexural investigation of a type steel-concrete composite beam structure able to provide an adequate bond between steel and concrete elements through the application simple reinforcement shear connector design, reinforcing bars bent into L-shapes. The cross sections involve inverted T-beam being embedded within reinforced (RC) flange slab. concentrates on elastic elastic-p...

The authors consider the determination of eigenforms a beam on elastic support parts. Elastic parts made rubber and laminated metal plates find wide use for seismic isolation bridges in earthquake-resistant construction. Determination structures is main stage when designing buildings resisting impacts. span structure girder considered as system uniformly distributed load, free vibrations which ...

Abstract At the European XFEL, we are designing a superconducting afterburner for SASE2 hard X-ray beamline. It will consist of series five undulator modules plus pre-series one called S-PRESSO. One module corresponds to two (SCU) coils 2m length phase shifter. Such an enable photon energies above 30 keV. We foresee install (SC) shifters in each keep correct delay between electron beam and beam...

This paper presents the comprehensive analytical design and numerical performance evaluation of novel millimetre-wave (mm-wave) switched-beam networks, based on the Rotman lens (RL) array feeding concept. These passive array devices have been designed for operation in the 28GHz frequency band, covering the whole 18–38 GHz frequency range. The primary objective of the work is to conduct a thorou...

We show, both theoretically and experimentally, that the propagation of optical vortices in free space can be analyzed by using the width [w(z)] of the host Gaussian beam and the inner and outer radii of the vortex beam at the source plane (z=0) as defined in [Opt. Lett.39, 4364 (2014)10.1364/OL.39.004364OPLEDP0146-9592]. We also studied the divergence of vortex beams, considered as the rate of...

The rapid growth in direct digital manufacturing technologies has opened the challenge of designing optimal micro-structures for high-performance components. Current topology optimization techniques do not work well for this type of problems and hence in this paper we propose a technique based on an implicit representation of the structural topology. The detailed microstructure is defined by a ...

In this report, emphasis is placed on issues related to selection and design of high-temperature, ion sources that have demonstrated the high ionization efficiency, species versatility, and operational reliability required at ISOL based radioactive ion beam facilities. In designing sources for ISOL applications, careful attention must be given to the following: selecting the most appropriate ma...

The concept of placing enormous Solar Power Satellite (SPS) systems in space represents one of a handful of new technological options that might provide large scale, environmentally clean base load power to terrestrial markets. Recent advances in space exploration have shown a great need for antennas with high resolution, high gain and low side lobe level (SLL). The last characteristic is of pa...

This paper features the mathematical modeling of a single input single output based Timoshenko smart beam. Further, this mathematical model is used to design a multirate output feedback based discrete sliding mode controller using Bartoszewicz law to suppress the flexural vibrations. The first 2 dominant vibratory modes is retained. Here, an application of the discrete sliding mode control in s...

The influence of the beam geometry on the quality factor and resonance frequency of resonant silicon cantilever beams vibrating in their fundamental in-plane flexural mode in water has been investigated. Compared to cantilevers vibrating in their first out-of-plane flexural mode, utilizing the in-plane mode results in reduced damping and reduced mass loading by the surrounding fluid. Quality fa...
