This paper presents a low cycle fatigue life curve by simulating a crack in a cover plate welded moment connection. Initiation of ductile fracture in steel is controlled by growth and coalescence of micro-voids. This research used a numerical method using finite element modeling and simulation of ductile crack initiation by a micromechanical model. Therefore, a finite element model of a cover p...

Plate reconstruction studies show that the Neotethys Ocean was closing due to convergence of Africa and Eurasia toward end Cretaceous. The period around 75 Ma reflects onset continental collision between two plates as continued be taken up mostly by subduction slab beneath Eurasia. Owen transform plate boundary in northeast accommodated fast northward motion Indian relative African plate. rest ...

• The flow field is found to vary greatly downstream of the perforated plate. conjugate heat transfer affects NO formation by relocating flame. preferential diffusion intensified due two-dimensionality flow. coupling effect these factors above determines generation rate. present work examines x emission characteristics a premixed micro-combustion system with plate implemented. For this, three-d...

Here we report the development of our Next Generation Automated Multiplexed Oligonucleotide Synthesizer (NG-1536-AMOS), capable of producing 1536 samples in a single run using a multi-well filtered titer plate. With the potential to synthesize up to 3456 samples per plate, we converted the BioRAPTR Flying Reagent Dispenser into an open-well system where spent reagents are drained to waste under...

In this work, growth and assembly of the micro polyhedral zinc oxide was performed using airbubble assisted Triton X100, as a templating agent. In absence of air bubbling in the reactionsystem the nano plate zinc oxide was synthesized. The prepared samples were characterized by Xraydiffraction (XRD), field emission scanning electron microscopy (FE-SEM) and UV-Visspectrop...

The analysis of a new viscometer that takes the form of an oscillating plate, fabricated from silicon using the methods of micro-electro-mechanical-systems (MEMS) is considered. The instrument is designed principally for experimental use in the oil industry. The plate is 1.6mm wide, 2.4mm long, and 20μm thick. It is suspended from a 0.4mm thick support by 48 square cross-section legs, each of l...

For realization of micro fluid power sources applicable to microfactory or micromachines using fluid power with high power density, a resonantly-driven piezoelectric micropump with newly devised check valve unit is developed and a practical application to micro press is attempted. First, a micro sheet valve having a floating valve-body inside valve chest to increase valve-opening and to decreas...

Low-frequency noise pollution in substations has a significant impact on the physical and mental health of workers. Reduction low-frequency is an urgent problem to solve for researchers. In this paper, different structures Al 2 O 3 -polyurethane composites micro-perforated plate were constructed, effects cavity depth, perforated plate, foam position sound absorption properties comprehensively i...

This work shows zero-power shock sensing for the combination of a micro-triboelectric generator and MEMS electrostatic actuator system where mechanical to causes it produce voltage, this voltage is used actuate Micro-Electro-Mechanical-system (MEMS) switch. For first time, we present fabrication process Triboelectric-Nano-Generator (TENG) with technology. The MEMS-TENG has suspended 1.5 mm × pl...
